For the 22nd time, Composites Germany has collected current key figures on the market for fiber-reinforced plastics. All member companies of the supporting associations of Composites Germany: AVK and Composites United as well as the associated partner VDMA were surveyed.
In order to ensure that the different surveys can be compared without any problems, no fundamental changes were made to the survey. Once again, mainly qualitative data was collected in relation to current and future market developments.

Critical assessment of the current business situation
After consistently positive trends were seen in the assessment of the current business situation in 2021, this has slipped since 2022. There is still no sign of a trend reversal in the current survey. The reasons for the negative sentiment are manifold and were already evident in the last survey.

At present, politicians do not seem to be able to create a more positive environment for the industry with appropriate measures. Overall, Germany in particular, but also Europe, is currently experiencing a very difficult market environment.

However, the main drivers of the current difficult situation are likely to be the persistently high energy and commodity/raw material prices. In addition, there are still problems in individual areas of the logistics chains, for example on the main trade/container routes, as well as a cautious consumer climate. A slowdown in global trade and uncertainties in the political arena are currently fueling the negative mood in the market.

Despite rising registration figures, the automotive industry, the most important application area for composites, has not yet returned to its former volume. The construction industry, the second most important key area of application, is currently in crisis. Although the order books are still well filled, new orders are often failing to materialize. High interest rates and material costs coupled with the high cost of living are having a particularly negative impact on private construction, but public construction is also currently unable to achieve the targets it has set itself. According to the ZDB (Zentralverband Deutsches Baugewerbe), the forecasts in this important sector remain gloomy: "The decline in the construction industry is continuing. Turnover will fall by 5.3% in real terms this year and we expect a further 3% drop next year. Residential construction remains responsible for the decline, which will slump by 11% in real terms this year and continue its downward trajectory at -13% in 2024."

It is not only the assessment of the general business situation that remains pessimistic. The situation of their own companies also continues to be viewed critically. The picture is particularly negative for Germany. Almost 50% of respondents are critical of the current business situation in Germany. The view of global business and Europe is somewhat more positive. Here, "only" 40% and 35% of respondents respectively assess the situation rather negatively.

Future expectations brighten
Despite the generally rather subdued assessment of the business situation, many of those surveyed appear to be convinced that the mood is improving, at least in Europe. When asked about their assessment of future general business development, the values for Europe and the world are more optimistic than in the last survey. The survey participants do not currently expect the situation in Germany to improve.

Respondents were more optimistic about their own company's future expectations for Europe and the global market.

The participants seem to be assuming a moderate short to medium-term recovery of the global economy. The forecasts are more optimistic than the assessment of the current situation. It is striking that the view of the German region is more critical in relation to Europe and the global economy. 28% of those surveyed expect the general market situation in Germany to develop negatively. Only 13% expect the current situation to improve. The figures for Europe and the world are better.

Investment climate remains subdued
The current rather cautious assessment of the economic situation continues to have an impact on the investment climate.

While 22% of participants in the last survey still assumed an increase in personnel capacity (survey 1/2023 = 40%), this figure is currently only 18%. In contrast, 18% even expect a decrease in personnel.

The proportion of respondents planning to invest in machinery is also declining. While 56% of respondents in the last survey still expected to make such investments, this figure has now fallen to 46%.

Different expectations of application industries
The composites market is characterized by a high degree of heterogeneity in terms of both materials and applications. In the survey, the participants are asked to give their assessment of the market development of different core areas.

The expectations are extremely varied. The two most important application areas are the mobility and construction/infrastructure sectors. Both are currently undergoing major upheavals or are affected by declines, which is also clearly reflected in the survey. Growth is expected above all in the wind energy and aviation sectors.

Growth drivers with slight shifts
In terms of materials, there has been a change in the assessment of growth drivers. While the respondents in the last 9 surveys always named GRP as the material from which the main growth impetus for the composites sector is to be expected, the main impetus is now once again expected to come from CFRP or across all materials.

There is a slight regional shift. Germany is seen less strongly as a growth driver. In contrast, Europe (excluding Germany) and Asia are mentioned significantly more.

Composites index points in different directions
The numerous negative influences of recent times continue to be reflected in the overall Composites Index. This continues to fall, particularly when looking at the current business situation. On the other hand, there is a slight improvement in expectations for future market development, although this remains at a low level.

The total volume of processed composites in Europe in 2022 was already declining, and a further decline must also be expected for 2023. This is likely to be around 5% again.

It remains to be seen whether it will be possible to counteract the negative trend. Targeted intervention, including by political decision-makers, would be desirable here. However, this cannot succeed without industry/business. Only together will it be possible to maintain and strengthen Germany as a business/industry location. For composites as a material group in general, there are still very good opportunities to expand the market position in both new and existing markets due to the special portfolio of properties. However, the dependency on macroeconomic developments remains. It is now important to develop new market areas through innovation, to consistently exploit opportunities and to work together to further implement composites in existing markets. This can often be achieved better together than alone. With its excellent network, Composites Germany offers a wide range of opportunities.

The next composites market survey will be published in July 2024.

JUMBO-Textil: "For us, leadership means team development."

With its high-quality technical narrow textiles, JUMBO-Textil stands for high-tech - whether woven, braided or knitted. As an elastic specialist and solution partner, the company develops and produces individual innovations for customers worldwide. The 70-strong team must be as diverse and flexible as the products it designs. Textination spoke to industrial engineer Carl Mrusek about the current challenges facing family businesses. Carl Mrusek, who has been Chief Sales Officer (CSO) at Textation Group GmbH & Co. KG, to which JUMBO-Textil belongs, for almost a year now, is in charge of strategic corporate development as well as other areas of responsibility.

 

With its high-quality technical narrow textiles, JUMBO-Textil stands for high-tech - whether woven, braided or knitted. As an elastic specialist and solution partner, the company develops and produces individual innovations for customers worldwide. The 70-strong team must be as diverse and flexible as the products it designs. Textination spoke to industrial engineer Carl Mrusek about the current challenges facing family businesses. Carl Mrusek, who has been Chief Sales Officer (CSO) at Textation Group GmbH & Co. KG, to which JUMBO-Textil belongs, for almost a year now, is in charge of strategic corporate development as well as other areas of responsibility.

 

"In a family business, tradition is the foundation, innovation is the way forward," they say. The image of family-run companies has changed significantly in recent years - old-fashioned values and outdated business concepts have given way to a strong corporate culture, a strong sense of regional responsibility and sustainable planning. How does JUMBO-Textil combine its corporate values and traditions with a contemporary management style?

Carl Mrusek: As a family business, there is a close bond between the employees and the company and vice versa; the continuity of human relationships is important and valuable. JUMBO-Textil also has a tradition of one thing in particular: contemporary corporate management, both technically and professionally, as well as in terms of management style and values. Especially in a family business, which is often managed by the same person for decades, it is crucial to question corporate values and management style and to promote change. A company that has been operating successfully internationally for almost 115 years must be adaptable. For us, reacting quickly to changes, even anticipating them and moving forward accordingly, is at the heart of smart business practices. The specialization in elastics in the 1920s is an example of the foresighted power of change, as is the strategically important turn to technical textiles in the 1970s. A recent example is the merger with vombaur under the umbrella of the Textation Group.

The most important thing in any company is its employees. We would not be able to attract and retain them with outdated traditions and working methods. For us, the focus is not on the company management, but on joint success, and in a complex world, this is usually the result of successful cooperation and not an announcement from the boss. Leadership clearly means setting and pursuing strategic goals, but today it also means team development. Finding the best people, bringing them together and motivating them to achieve the goal.

 

Team spirit and vision development: How do you achieve this at JUMBO-Textil?

Carl Mrusek: As a team! JUMBO-Textil has systematically expanded its management team. In addition to the Managing Director, our CEO Andreas Kielholz, the Chief Operational Officer Patrick Kielholz, the Chief Financial Officer Ralph Cammerath, the Chief Technology Officer Dr. Sven Schöfer and myself as Chief Sales Officer work here. This shows that we are convinced of the idea of cooperation: We also work together on corporate development and strategic issues. The same applies to the individual teams - in organizational specialist teams or in interdisciplinary project teams. The tasks for which we are responsible may be different, but each is equally important.

 

Is that why you start the introduction of contact persons on your website with the Junior Sales Manager? And the C-level representatives are at the end?

Carl Mrusek: Yes, all JUMBO-Textil heads are the head of the company for us. All JUMBO-Textil faces represent the company. This is also reflected in the order of the contact persons on the website. Visitors should be able to quickly find the person who can help them and not find out who runs the company. That's what the legal notice is for. (laughs)

 

What is JUMBO-Textil's mission statement and vision for the future, and what needs to change in order to achieve this vision?

Carl Mrusek: We are currently working on the strategic direction of the Textation Group, which JUMBO-Textil GmbH & Co. KG and vombaur GmbH & Co. KG are part of. In this context, we have developed the Group's corporate vision and mission and updated our mission statement. This serves as a foundation for strategy development and is only sustainable if employees are involved in this process through surveys and workshops. I don't want to give too much away yet, but this much is already clear: strong teams, the right people in the right place, taking responsibility at all levels, sustainability as the basis for innovation - these will be the four cornerstones. You can already see from this: To achieve our vision, we cannot flip a switch. We must always remain open to change, always new - from product development to personnel recruitment. But as I said, we have a tradition of doing this.

 

JUMBO-Textil is not an industry specialist, but combines expertise for demanding high-tech narrow textiles. Who is in charge of challenging customer projects - do you decide in a team or rather top-down, where is the responsibility for an order placed?

Carl Mrusek: As a team, we decide which projects to implement and how to prioritize them. The corporate strategy determines the "direction of travel". In addition to the sales side, the development side of new projects also plays a decisive role. I therefore coordinate intensively with Dr. Sven Schöfer (CTO) and his team, as the focus here is on the technical development and implementation of our products. In the end, project processing is always a team effort between Sales and Development in close cooperation with Production..

 

Between above-standard pay, a 4-day week and the much-vaunted work-life balance in the current situation on the job market, companies are more likely to be in the position of applicants than vice versa. What are you doing to remain attractive as an employer for new colleagues? And how do you keep the enthusiasm of your skilled employees at a consistently high level?

Carl Mrusek: An important approach for us is education. Training young people and proving to them during their apprenticeship: JUMBO-Textil is your place to be. We therefore already start recruiting skilled workers through our school visits and school internships. As a state-of-the-art company, we offer an attractive salary level and a pleasant and healthy working environment.

Applicants today also often want to organize their working hours and work arrangements individually and flexibly, for a variety of reasons. With modern working models and thanks to our ongoing progress in digitalization, we support them wherever possible. People also want to work for a company that they can identify with. Environmental and climate protection are just as important to our employees and applicants as social standards in our supply chain. The fact that we have set ourselves ambitious goals with our sustainability strategy and are consistently pursuing them with firmly scheduled steps - our climate-neutral energy generation is a concrete example that has already been implemented. Furthermore, we vigorously encourage our business partners to respect human and employee rights and are committed to the Code of Conduct of the German textile and fashion industry. All of this helps us to recruit staff.

 

What larger, more capital-intensive companies can partially make up for with financial resources, SMEs have to manage through agility and adaptability - especially in situations of crisis. To what extent are these requirements also reflected in your organizational structure and the requirements profile for employees?

Carl Mrusek: Exactly, that is the advantage that family businesses have over large corporations: We can make decisions quickly and react on a daily basis if necessary. Hierarchies are flat and coordination processes are short. An exciting suggestion doesn't have to be prepared by agencies and coordinated across several levels before it is approved by the management and can be implemented. The go-ahead can also come immediately over lunch: "Great idea, we'll do it." In a corporate group, this fails because only very few employees have the opportunity to have lunch with the management. - And we only talk about business in exceptional cases. Most of the time, the break is about family, the weather, sports and leisure plans - lunch topics, in other words. - We need responsible team players who are willing to make a change. People who work with others on an equal footing, who are committed to the company and its goals with drive and expertise and who are keen to try new things.

 

It now takes much more than a fruit basket and a gym to motivate current and potential employees. Working in a meaningful way and participating in a climate-friendly transformation is particularly important to many people. What does JUMBO-Textil do specifically to not just quote SDGs in a statement, but to live them in everyday company life?

Carl Mrusek: We have set ourselves a specific climate target: By 2035, our administrative and production operations at our headquarters will be climate-neutral. Realistic steps have been defined to achieve this. We have already achieved an important interim goal: at our headquarters in Sprockhövel, we only use green electricity from the sun, wind and water. We offset the unavoidable emissions for our heat generation with CO2 compensation services. We are also developing more and more products from recyclable and recycled materials. Our vehicle fleet is currently being converted to purely electric or hybrid models.

 

Diversification and internationalization are part of every corporate strategy these days. But what do these terms mean for the management style of a medium-sized company in Sprockhövel? Do you consciously build interdisciplinary international teams?

Carl Mrusek: We live in a hyper-diverse society. This is also reflected in our company. Our teams consist of people with different international backgrounds, without us having to actively control this. The age structure is now also very mixed. We see the different perspectives as an asset, an opportunity and a success factor. We - and that ultimately means our customers and their projects - benefit from the variety of perspectives that flow into our solutions. As with many companies in the technical textiles sector, the proportion of women in some teams is still somewhat unbalanced. However, it is fortunately increasing steadily.

 

Generational change and succession planning are core issues for family-run companies. How important is it for JUMBO-Textil to professionalize its management team and to what extent is the company open to external specialists and managers?

Carl Mrusek: A company that closes its doors to external specialists and managers is also closing a door to success. That would be foolish. At JUMBO-Textil, we try to combine and balance the close ties, personal continuity and flexibility of a family-run company, the passion and innovative spirit of a start-up and the solidity and financial strength of a group. With Patrick Kielholz as COO, the next generation of the family is represented at management level, as is the external view and the diversity of perspectives provided by the other new members at C-level. The Textation Group, which also includes Patrick Kielholz's brother Kevin Kielholz, supports the company and enables it to think and act bigger than medium-sized family businesses often do. JUMBO-Textil is an elastic specialist. And what distinguishes our product also distinguishes us as an organization. We span the advantages of a family business as well as those of a start-up and a group. If I may use the image of elasticity here and not stretch it too far. (laughs)

Checking clothing using a smartphone, AI and infrared spectroscopy

Researchers at Fraunhofer have developed an ultra-compact near-infrared spectrometer suitable for recognizing and analyzing textiles. Mixed fabrics can also be reliably identified through the combination of imaging, special AI (artificial intelligence) algorithms and spectroscopy. The technology could be used to optimize recycling old clothing, so old apparel could be sorted according to type. A highly miniaturized version of the system can even fit into a smartphone. This could lead to a host of new applications for end-users in everyday life — from checking clothes when out shopping to detecting counterfeits.

Researchers at Fraunhofer have developed an ultra-compact near-infrared spectrometer suitable for recognizing and analyzing textiles.

This could lead to a host of new applications for end-users in everyday life — from checking clothes when out shopping to detecting counterfeits.

Infrared spectrometers are powerful measuring instruments when it comes to non-destructive analysis of organic materials. The Fraunhofer Institute for Photonic Microsystems IPMS in Dresden has recently developed a spectral analyzer system that recognizes and analyzes textile fabrics. The system can also reliably recognize mixed fabrics. Possible applications range from checking fabrics when out shopping to cleaning garments correctly, and even sustainable, sorted recycling. The spectrometer is so tiny, it can be integrated into a smartphone.

Researchers at Fraunhofer rely on near-infrared (NIR) spectroscopy to achieve the required reliability and accuracy when identifying textiles. The system works for wavelengths between 950 and 1900 nanometers, which is close to the visible spectrum. Advantages of near-infrared technology include being easy to use and having a wide range of applications. “We combine NIR spectroscopy with imaging and AI to achieve higher accuracy when recognizing and analyzing objects,” explains Dr. Heinrich Grüger, research scientist in the Sensoric Micromodules department at Fraunhofer IPMS.

How textile analysis works
Firstly, a conventional camera module captures an image of the garment. The AI selects a specific point from the fabric’s image data to be examined by the spectral analyzer module. Light reflected from the fabric is captured by the spectrometer module. There, it passes through an entrance slit, is transformed into parallel light beams using a collimating mirror and projected onto a grating using a scanning mirror. Depending on the angle of incidence and exit, the grating splits the light beams into different wavelengths. Light reflected from the grating is directed by the scanner mirror to a detector which captures the light as an electrical signal. An A/D converter then digitizes these signals, which are subsequently analyzed in the signal processor. The resulting spectrometric profile for the textile fabric reveals which fibers it is made from by comparing to a reference database.“ The optical resolution is 10 nanometers. This high resolution means the NIR spectrometer can also use AI to identify mixed fabrics such as items of clothing made from polyester and cotton,” says Grüger. Measuring just 10 mm × 10 mm and being 6.5 mm thick, the system is so compact it could easily be integrated into a standard smartphone.

Recycling old clothing
Grüger sees an important application for the AI-controlled spectrometer when it comes to recycling. According to the Federal Statistical Office of Germany, approximately 176,200 tons of textile and clothing waste was collected from private homes in Germany in 2021. NIR spectroscopy could improve recycling efficiency and reduce the mountain of old clothing. This would enable companies that recycle old clothing to sort it more efficiently and faster. Textiles that are still in one piece, for instance, go to the second-hand trade. Damaged textiles are sorted for recycling, and the fibers they are made from, such as linen, silk, cotton or lyocell, can be reused. Severely soiled textiles would be incinerated or processed into insulation mats, for example. Spectroscopic identifies and sorts textiles more accurately and much faster than a human can.

If NIR spectroscopy was to be integrated into a smartphone, end-users might also benefit from the Fraunhofer institute’s technology. When buying clothes, a quick check with a smartphone reveals whether that expensive silk scarf is genuinely made from silk, or whether that exclusive dress from the fashion label is not instead a counterfeit, exposed through an alternative mix of fabrics. And should the label with the cleaning instructions no longer be legible, the smartphone has a textile scanner to identify the fabric and so determine the appropriate wash cycle.

Food check and dermatology
Researchers at Fraunhofer IPMS can even envisage applications beyond the textile industry. Smartphones fitted with spectrometers might be used to provide information about the quality of groceries such as fruit and vegetables when out shopping. The technology might conceivably also be used to examine skin. A quick scan with the cell phone spectrometer could identify particularly dry or greasy patches. Perhaps applications in medical diagnostics might even be conceivable — examining patches of skin where a melanoma is suspected, for example — but this would need professional involvement too.

"After all, a spaceship is not made off the peg."

Interview with vombaur - pioneers in special textiles
Technical narrow textiles, custom solutions, medium-sized textile producer and development partner for filtration textiles, composite textiles and industrial textiles: vombaur. Digitalisation, sustainability, energy prices, pioneering work and unbroken enthusiasm – Textination spoke to two passionate textile professionals: Carl Mrusek, Chief Sales Officer (CSO), and Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles, at vombaur GmbH, which, as well as JUMBO-Textil, belongs to the Textation Group.
 

Interview with vombaur - pioneers in special textiles
Technical narrow textiles, custom solutions, medium-sized textile producer and development partner for filtration textiles, composite textiles and industrial textiles: vombaur. Digitalisation, sustainability, energy prices, pioneering work and unbroken enthusiasm – Textination spoke to two passionate textile professionals: Carl Mrusek, Chief Sales Officer (CSO), and Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles, at vombaur GmbH, which, as well as JUMBO-Textil, belongs to the Textation Group.
 
If you look back at your history and thus to the beginnings of the 19th century, you will see a ribbon manufactory and, from 1855, a production of silk and hat bands. Today you produce filtration textiles, industrial textiles and composites textiles. Although you still produce narrow textiles today, the motto "Transformation as an opportunity" seems to be a lived reality at vombaur.
 
Carl Mrusek, Chief Sales Officer: Yes, vombaur has changed a few times in its almost 220-year history.  Yet the company has always remained true to itself as a narrow textiles manufacturer. This testifies to the willingness of the people in the company to change and to their curiosity. Successful transformation is a joint development, there is an opportunity in change. vombaur has proven this many times over the past almost 220 years: We have adapted our product portfolio to new times, we have built new factory buildings and new machinery, we have introduced new materials and developed new technologies, we have entered into new partnerships – as most recently as part of the Textation Group. We are currently planning our new headquarters. We are not reinventing ourselves, but we will go through a kind of transformation process with the move into the brand new, climate-friendly high-tech space.

 

Could you describe the challenges of this transformation process?
 
Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles: A transformation usually takes place technically, professionally, organisationally and not least – perhaps even first and foremost – culturally. The technical challenges are obvious. Secondly, in order to manage and use the new technologies, appropriate expertise is needed in the company. Thirdly, every transformation entails new processes, teams and procedures have to be adapted. And finally, fourthly, the corporate culture also changes. Technology can be procured, expertise acquired, the organisation adapted. Time, on the other hand, cannot be bought. I therefore consider the greatest challenge to be the supply of human resources: In order to actively shape the transformation and not be driven by development, we need sufficient skilled workers.

 

Visiting your website, the claim "pioneering tech tex" immediately catches the eye. Why do you see your company as a pioneer, and what are vombaur's groundbreaking or pioneering innovations?

Carl Mrusek: With our unique machine park, we are pioneers for seamless circular woven textiles. And as a development partner, we break new ground with every order. We are always implementing new project-specific changes: to the end products, to the product properties, to the machines. It happens regularly that we adapt a weaving machine for a special seamless woven shaped textile, sometimes even develop a completely new one.
 
With our young, first-class and growing team for Development and Innovation led by Dr. Sven Schöfer, we repeatedly live up to our promise of "pioneering tech tex" by developing special textile high-tech solutions with and for our customers. At the same time, we actively explore new potentials. Most recently with sustainable materials for lightweight construction and research into novel special filtration solutions, for example for the filtration of microplastics. A state-of-the-art textile technology laboratory is planned for this team in the new building.

 

The development of technical textiles in Germany is a success story. From a global perspective, we manage to succeed with mass-produced goods only in exceptional cases. How do you assess the importance of technical textiles made in Germany for the success of other, especially highly technological industries?

Carl Mrusek: We see the future of industry in Europe in individually developed high-tech products. vombaur stands for high-quality, reliable and durable products and made-to-order products. And it is precisely this – custom-fit products, instead of surplus and throwaway goods – that is the future for sustainable business in general.

 

What proportion of your production is generated by being project-based as opposed to a standard range, and to what extent do you still feel comfortable with the term "textile producer"?

Johannes Kauschinger: Our share of special solutions amounts to almost 90 percent. We develop technical textile solutions for our customers' current projects. For this purpose, we are in close contact with the colleagues from our customers' product development departments. Especially in the field of composite textiles, special solutions are in demand. This can be a component for space travel – after all, a spaceship is not manufactured off the peg. We also offer high-quality mass-produced articles, for example in the area of industrial textiles, where we offer round woven tubulars for conveyor belts. In this sense, we are a textile producer, but more than that: we are also a textile developer.

 

In August, Composites Germany presented the results of its 21st market survey. The current business situation is viewed very critically, the investment climate is becoming gloomier and future expectations are turning negative. vombaur also has high-strength textile composites made of carbon, aramid, glass and hybrids in its portfolio. Do you share the assessment of the economic situation as reflected in the survey?

Carl Mrusek: We foresee a very positive development for vombaur because we develop in a very solution-oriented way and offer our customers genuine added value. This is because future technologies in particular require individual, reliable and lightweight components. This ranges from developments for the air taxi to wind turbines. Textiles are a predestined material for the future. The challenge here is also to offer sustainable and recyclable solutions with natural raw materials such as flax and recycled and recyclable plastics and effective separation technologies.

 

There is almost no company nowadays that does not use the current buzzwords such as climate neutrality, circular economy, energy efficiency and renewable energies. What is your company doing in these areas and how do you define the importance of these approaches for commercial success?

Carl Mrusek: vombaur pursues a comprehensive sustainability strategy. Based on the development of our mission statement, we are currently working on a sustainability declaration. Our responsibility for nature will be realised in a very concrete and measurable way through our new building with a green roof and solar system. In our product development, the high sustainability standards – our own and those of our customers – are already flowing into environmentally friendly and resource-saving products and into product developments for sustainable projects such as wind farms or filtration plants.

 

Keyword digitalisation: medium-sized businesses, to which vombaur belongs with its 85 employees, are often scolded for being too reluctant in this area. How would you respond to this accusation?

Johannes Kauschinger:

We often hear about the stack crisis at the present time. Based on this, we could speak of the stack transformation. We, the small and medium-sized enterprises, are transforming ourselves in a number of different dimensions at the same time: Digital transformation, climate neutrality, skilled labour market and population development, independence from the prevailing supply chains. We are capable of change and willing to change. Politics and administration could make it a bit easier for us in some aspects. Key words: transport infrastructure, approval times, energy prices. We do everything we can on our side of the field to ensure that small and medium-sized enterprises remain the driving economic force that they are.

 

 

How do you feel about the term shortage of skilled workers? Do you also take unconventional paths to find and retain talent and skilled workers in such a specialised industry? Or does the problem not arise?

Carl Mrusek: Of course, we are also experiencing a shortage of skilled workers, especially in the industrial sector. But the development was foreseeable. The topic played a major role in the decision to move together with our sister company JUMBO-Textil under the umbrella of the Textation Group. Recruiting and promoting young talent can be better mastered together – for example with cross-group campaigns and cooperations.

 

If you had to describe a central personal experience that has shaped your attitude towards the textile industry and its future, what would it be?

Johannes Kauschinger: A very good friend of my family pointed out to me that we live in an area with a very active textile industry, which at the same time has problems finding young talents. I visited two companies for an interview and already on the tour of each company, the interaction of people, machines and textiles up to the wearable end product was truly impressive. In addition, I was able to learn a profession with a very strong connection to everyday life. To this day, I am fascinated by the wide range of possible uses for textiles, especially in technical applications, and I have no regrets whatsoever about the decision I made back then.

Carl Mrusek: I came into contact with the world of textiles and fashion at a young age. I still remember the first time I went through the fully integrated textile production of a company in Nordhorn with my father Rolf Mrusek. Since then, the subject has never left me. Even before I started my studies, I had made a conscious decision to pursue a career in this industry and to this day I have never regretted it, on the contrary. The diversity of the special solutions developed in the Textation Group fascinates me again and again.

Composites Germany: Investment climate cloudy

  • Results of the 21st Composites Market Survey
  • Critical assessment of the current business situation
  • Future expectations turn negative
  • Expectations for application industries vary
  • Growth drivers with only slight shifts
  • Composites index points in different directions

This is the 21st time that Composites Germany (www.composites-germany.de) has identified the latest performance indicators for the fibre-reinforced plastics market. The survey covered all the member companies of the umbrella organisations of Composites Germany: AVK and Composites United, as well as the associated partner VDMA.

As before, to ensure a smooth comparison with previous surveys, the questions in this half-yearly survey have been left unchanged. Once again, the data obtained in the survey is largely qualitative and relates to current and future developments in the market.

The survey covered all the member companies of the umbrella organisations of Composites Germany: AVK and Composites United, as well as the associated partner VDMA.

As before, to ensure a smooth comparison with previous surveys, the questions in this half-yearly survey have been left unchanged. Once again, the data obtained in the survey is largely qualitative and relates to current and future developments in the market.

Critical assessment of current business situation
After consistently positive trends were evident in the assessment of the current business situation in 2021, this slipped in 2022. For the third time in a row, the current survey shows pessimistic assessments. The reasons for the negative mood are manifold. However, the main drivers are likely to be the still high energy and commodity prices. In addition, there are still problems in individual areas of the logistics chains as well as a restrained consumer climate. Despite rising registration figures, the automotive industry, the most important application area for composites, has not yet returned to its former volume. This also illustrates the change in strategy of European OEMs to move away from volume models towards high-margin vehicle segments. The construction industry, the second central area of application, is currently in crisis. Although the order books are still well filled in many cases, new orders are often not forthcoming. High in-terest rates and material costs combined with a high cost of living are placing a heavy burden on private construction in particular. A real decline in turnover of 7% is currently expected for the construction industry in 2023.

The assessment of the business situation of their own company is also increasingly pessimistic. The picture is particularly negative for Germany. Almost 50% of respondents (44%) are critical of the current business situation. The view of global business and Europe is somewhat more positive. Here, "only" 36% and 33% of the respondents respectively assess the situation rather negatively.

Future expectations turn negative
Following the rather pessimistic assessment of the current business situation, future business expectations also turn negative. After an increase in the last survey, the cor-responding indicators for the general business situation are now clearly pointing down-wards. The respondents are also more pessimistic about their own com-pany's future expectations.

The participants apparently do not expect the situation to improve in the short term. It is also noticeable here that the view of Germany as a region is more critical in relation to Europe and the global economy. 22% of the respondents expect a negative develop-ment in Germany. Only 13% expect the current situation to improve. The indicators for Europe and the world are better.

Investment climate clouds over
The currently rather cautious assessment of the economic situation and the pessimistic outlook also have an impact on the investment climate.
Whereas in the last survey 40% of the participants still expected an increase in person-nel capacity, this figure is currently only 18%. On the other hand, 12% even expect a decline in the area of personnel.

The share of respondents planning to invest in machinery is also declining. While 71% of respondents in the last survey expected to invest in machinery, this figure has now fallen to 56%.
 
Expectations of application industries differ
The composites market is characterised by strong heterogeneity, both in terms of materials and applications. In the survey, the participants were asked to give their assessment of the market development in different core areas. The expectations are extremely varied.

The weaknesses already described in the most important core markets of transport and construction/infrastructure are clearly evident. Growth is expected above all in the wind energy and aviation sectors. Expectations about future market developments, on the other hand, are significantly more positive than the figures presented here might suggest.

Growth drivers with only slight shifts
The paradigm shift in materials continues. While in the first 13 surveys the respondents always named CFRP as the material from which the main growth impulses for the com-posites sector are to be expected, the main impulses are now assumed to come from GRP or across all materials. There is a slight regional shift. At present it is mainly North America that is expected to provide the main growth impulses for the industry. Europe and Asia are losing ground slightly.

Composites index points in different directions
The numerous negative influences of recent times are now also reflected in the overall composites index. All indicators are weakening. Both the current and the future assessment are turning negative.  

The total volume of composites processed in Europe in 2022 was already slightly down compared to 2021. After a good first quarter of 2022, there is currently a clear cooling of activity. It remains to be seen whether it will be possible to counteract the negative development. Targeted intervention, including by political decision-makers, would be desirable here. However, this cannot succeed without industry/business. Only together will it be possible to further strengthen Germany's position as a business location and to maintain or expand its position against the backdrop of a weakening global economy. There are still very good opportunities for composites to expand their market position in new and existing markets. However, the dependence on macroeconomic developments remains. The task now is to open up new market fields through innovations, to consistently exploit opportunities and to work together to further implement composites in existing markets. This can often be done better together than alone. With its excellent network, Composites Germany offers a wide range of opportunities.

Point of View: Let’s end fast fashion

Focusing on short-term profit isn’t sustainable. So what can we do to move in the right direction: favour resilience over efficiency in all industries.

We buy cheap products knowing we’ll need to replace them soon. We throw out used items rather than repairing or re-using them. Our employers plan in terms of financial quarters despite hoping to remain relevant and resilient longer-term. Even countries prioritise short-term economic output, focusing on gross domestic product (GDP) above any other indicator.

But does this way of living, working and weighing decisions make sense in the 21st century?

Our global obsession with economic short-term efficiency – and how to transform it – is a conundrum that Professor of Sustainability Management Minna Halme has been thinking about for most of her career. Even as a business school student, she felt flummoxed by how focused her classes were on short-term goals.

Focusing on short-term profit isn’t sustainable. So what can we do to move in the right direction: favour resilience over efficiency in all industries.

Our employers plan in terms of financial quarters despite hoping to remain relevant and resilient longer-term. Even countries prioritise short-term economic output, focusing on gross domestic product (GDP) above any other indicator.

But does this way of living, working and weighing decisions make sense in the 21st century?

Our global obsession with economic short-term efficiency – and how to transform it – is a conundrum that Professor of Sustainability Management Minna Halme has been thinking about for most of her career. Even as a business school student, she felt flummoxed by how focused her classes were on short-term goals.

'It was about selling more, about maximising shareholder profits, about economic growth – but not really asking, Why? What's the purpose of all this?'

Halme says. 'Even 20-year-old me somehow just felt that this was strange.

'What are we trying to do here? Are we trying to create a better economy for all, or most, people? Whose lives are we trying to improve when we are selling more differently-packaged types of yoghurt or clothes that quickly become obsolete?'

Halme has devoted her career to studying these questions. Today, she is a thought leader in innovative business practices, with recognitions including serving on Finland's National Expert Panel for Sustainable Development and on the United Nation's Panel on Global Sustainability.

Her ultimate goal? Pioneering, researching and advocating for alternative ways of thinking that prioritise values like long-term economic sustainability and resilience – alternatives that she and other experts believe would provide more lasting, widespread benefit to all.

How traditional indicators have failed
One way in which our preference for economic efficiency shapes how we measure a country's overall well-being or status is GDP. This isn't the fault of the originator of the modern concept of GDP, who specifically warned against using it in this way in the 1930s.

'GDP was never meant to tell us about the wellbeing of the citizens of a country,' Halme says. Seventy-five years ago, however, it was easy to conflate the two. Many countries were more committed to redistributing their wealth among their citizens, and population surveys show that until the 1970s, GDP often correlated with general wellbeing.

But with the rise of increasingly heedless free-market capitalism, this became less the case – and GDP's shortcomings became all the more apparent. 'We are in a situation where the wealth distribution is more and more trickling up to those who already have capital. Those who don't have it are in declining economic positions,' Halme says. In fact, the richest 1% of the global population now own nearly half of the world's wealth.

Some governments, such as Finland's, do take indicators of environmental and social progress into account. 'But none is considered as important for decision-making as GDP,' Halme says – and GDP is also considered the arbiter of a government's success. It is that attitude that, through her work advising the Finnish government on sustainability practises as well as in her own research, Halme is trying to shift.

Where industries have failed
Our often-exclusive focus on the economy – and, in particular, on making profits as quickly and efficiently as possible – doesn’t provide a clear picture of how everyone in a society is faring. Worse yet, it has encouraged industries to act with a short-term view that makes for longer-term problems.

Fast fashion is one example. At the moment, supply chains for clothing – as for most other goods – are linear. Raw materials come from one place and are transformed step by step, usually at different factories around the world, using materials, energy and transport that are “cheap” because their high environmental costs aren’t included. They are ultimately purchased by a consumer, who wears the product temporarily before discarding it. To expand profit margins, the industry pushes fast-changing trends. A shocking amount of this clothing ends up in landfill – some of it before it's even been worn.

As the COVID lockdowns showed, this kind of linear supply system isn't resilient. Nor is it sustainable.

Currently, fashion is estimated to be the world's second most polluting industry, accounting for up to 10% of all greenhouse gas emissions. Aalto University researchers have reported that the industry produces more than 92 million tonnes of landfill waste per year. By 2030, that is expected to rise to 134 million tonnes.

Cutting fashion's carbon footprint isn't just good for the environment; it will help the longer-term prospects of the industry itself. 'With this kind of wrong thinking about efficiency, you're eroding the basis of our long-term resilience both for ecology and for society,' Halme says.

Getting out of this trap, she and other researchers say, requires a complete paradigm shift. 'It's really difficult to just tweak around the edges,' she says.

Towards resilience
For several years, Halme researched and studied ecological efficiency, looking at ways that businesses could make more products with a smaller environmental impact. But gradually she realised this wasn't the answer. Although businesses could innovate to have more efficient products and technologies, their absolute use of natural resource use kept growing.

'I began to think, "If not efficiency, then what?"' Halme says. She realised the answer was resilience: fostering ways for systems, including the environment, to continue and even regenerate in the future, rather than continuing to degrade them in the present.

The solution isn’t more of anything, even ‘sustainable’ materials. It’s less.

'The only way to fix fast fashion is to end it,' Halme and her co-authors write. This means designing clothes to last, business models that make reuse and repair more accessible, and prioritising upcycling. Recycling systems also need to be overhauled for when an item really is at the end of its life – particularly regarding blended synthetic fibres, which are difficult to separate and break down.

This would upend the current focus on short-term revenue above all else. And, says Halme, it is one more example of how we need better ways to measure the success of these industries, taking into account factors like resilience and sustainability – rather than just short-term profits.

And while individuals can make an impact, these changes ultimately have to be industry-led.

'Textiles are a good example, because if they break quickly, and if you don't have repair services nearby, or if the fabrics are of such lousy quality that it doesn't make any sense to repair them, then it's too much trouble for most people,' Halme says. 'So most solutions should come from the business side. And the attempt should be to make it both fashionable and easy for consumers to make ecologically and socially sustainable choices.'

What will it take?
The ultimate challenge, says Lauri Saarinen, Assistant Professor at the Aalto University Department of Industrial Engineering and Management, is how to shift towards a more sustainable model while keeping companies competitive. But he believes there are ways.

One option is to keep production local. 'If we compete with low-cost, offshore manufacturing by doing things more locally, and in a closed loop, then we get the double benefit of actually providing some local work and moving towards a more sustainable supply chain,' Saarinen says. For example, if clothing were produced closer to consumers, it would be easier to send garments back for repair or for brands to take back used items and resell them.

Local production is yet another example of the need to rethink how we measure societal success. After all, outsourcing and offshoring in favour of cheaper production may appear to cut costs in short term, but this is done at the expense of what Halme and other experts argue really matters – longer-term economic viability, resilience and sustainability.

Shifting towards this kind of thinking isn't easy. Still, Saarinen and Halme have seen promising signs.

In Finland, for example, Halme points to the start-up Menddie, which makes it easy and convenient to send items away for repairs or alterations. She also highlights the clothing and lifestyle brand Marimekko, which re-sells its used items in an online secondhand shop, and the Anna Ruohonen label, a made-to-measurecollection and customer on-demand concept which creates no excess garments.

It's these kinds of projects that Halme finds interesting – and that, through her work, she hopes to both advocate for and pioneer.

At the moment, she says, these changes haven't yet added up to a true transformation. On a global scale, we remain far from a genuine shift towards longer-term resilience. But as she points out, that can change quickly. After all, it has in the past. Just look at what got us here.

'The pursuit of economic growth became such a dominant focus in a relatively short time – only about seven decades,' she says. 'The shift toward longer-term resilience is certainly possible. Scientists and decision-makers just need to change their main goal to long-term resilience. The key question is, are our most powerful economic players wise enough to do so?'

As part of her research, Halme has led projects pioneering the kinds of changes that the fashion industry could adapt. For example, along with her Aalto colleague Linda Turunen, she recently developed a measurement that the fashion industry could use to classify how sustainable a product really is – measuring things like its durability, how easily it can be recycled, and whether its production uses hazardous chemicals – which could help consumers to decide whether to buy. Her colleagues curated a recent exhibition that showcased what we might be wearing in a sustainable future, such as a leather alternative made from discarded flower cuttings, or modular designs to get multiple uses from the same garment – turning a skirt into a shirt, for example.
 
Because all of this requires longer-term thinking, innovation and investment, industry is reticent to make these shifts, Halme says. One way to encourage industries to change more quickly is with regulation. In the European Union, for example, an updated set of directives now requires companies with more than 500 employees to report on a number of corporate responsibility factors, ranging from environmental impact to the treatment of employees. These rules won't just help inform consumers, investors and other stakeholders about a company's role in global challenges. They’ll also help assess investment risks – weighing whether a company is taking the actions necessary to be financially resilient in the long-term.

Wearable Connector Technology - Benefits to Military, Medicine and beyond

What comes to mind when you think about “wearable technology?” In 2023, likely a lot, at a time when smartwatches and rings measure heart rates, track exercise and even receive text messages. Your mind might even drift to that “ugly” light-up sweater or costume you saw last Halloween or holiday season.

At the Wilson College of Textiles, though, researchers are hard at work optimizing a truly new-age form of wearable technology that can be proven useful in a wide range of settings, from fashion and sports to augmented reality, the military and medicine.

Currently in its final stages, this grant-funded project could help protect users in critical situations, such as soldiers on the battlefield and patients in hospitals, while simultaneously pushing the boundaries of what textiles research can accomplish.

At the Wilson College of Textiles, though, researchers are hard at work optimizing a truly new-age form of wearable technology that can be proven useful in a wide range of settings, from fashion and sports to augmented reality, the military and medicine.

Currently in its final stages, this grant-funded project could help protect users in critical situations, such as soldiers on the battlefield and patients in hospitals, while simultaneously pushing the boundaries of what textiles research can accomplish.

“The goals set for this research are quite novel to any other literature that exists on wearable connectors” says Shourya Dhatri Lingampally, Wilson College of Textiles graduate student and research assistant involved in the project alongside Wilson College Associate Professor Minyoung Suh.

Ongoing since the fall of 2021, Suh and Lingampally’s work focuses on textile-integrated wearable connectors, a unique, high-tech sort of “bridge” between flexible textiles and external electronic devices. At its essence, the project aims to improve these connectors’ Technology Readiness Level — a key rating used by NASA and the Department of Defense used to assess a particular technology’s maturity.

To do this, Lingampally and her colleagues’ research examines problems that have, in the past, affected the performance of wearable devices.

Sure, these advances may benefit fashion, leading to eccentric shirts, jackets, or accessories — “to light up or change its color based on the wearer’s biometric data,” Lingampally offers — the research has roots in a much deeper mission.

Potential benefits to military, medicine and beyond
The project is funded through more than $200,000 in grant money from Advanced Functional Fabrics of America (AFFOA), a United States Manufacturing Innovation Institute (MII) located in Cambridge, Massachusetts. The mission of AFFOA is to support domestic manufacturing capability to support new technical textile products, such as textile-based wearable technologies.

A key purpose of the research centers around improving the functionality of wearable monitoring devices with which soldiers are sometimes outfitted to monitor the health and safety of their troops remotely.

Similar devices allow doctors and other medical personnel to remotely monitor the health of patients even while away from the bedside.

Though such technology has existed for years, it’s too often required running wires and an overall logistically-unfriendly design. That could soon change.

“We have consolidated the electronic components into a small snap or buckle, making the circuits less obtrusive to the wearer,” Lingampally says, explaining the team’s innovations, which include 3D printing the connector prototypes using stereolithography technology.

“We are trying to optimize the design parameters in order to enhance the electrical and mechanical performance of these connectors,” she adds.

To accomplish their goals, the group collaborated with NC State Department of Electrical and Computer Engineering Assistant Research Professor James Dieffenderfer. The team routed a variety of electrical connections and interconnects like conductive thread, epoxy and solder through textile materials equipped with rigid electronic devices.

They also tested the components for compatibility with standard digital device connections like USB 2.0 and I2C.

Ultimately, Lingampally hopes their work will make wearable technology not only easier and more comfortable to use, but available at a lower price, too.

“I would like to see them scaled, to be mass manufactured, so they can be cost efficient for any industry to use,” she explains.

In a bigger-picture sense, though, her team’s work is reinforcing the far-reaching boundaries of what smart textile research can accomplish; a purpose that stretches far beyond fashion or comfort.

Pushing the boundaries of textiles research
Suh and Lingampally’s work is just the latest breakthrough research originating from the Wilson College of Textiles that’s aimed at solving critical problems in the textile industry and beyond.

“The constant advancements in technology and materials present immense potential for the textile industry to drive positive change across a range of fields from fashion to healthcare and beyond,” Lingampally, a graduate student in the M.S. Textiles program, says, noting the encouragement she feels in her program to pursue innovation and creativity in selecting and advancing her research.

Additionally, in the fiber and polymer science doctoral program, which Suh does research with, candidates focus their research on a seemingly endless array of STEM topics, ranging from forensics to medical textiles, nanotechnology and, indeed, smart wearable technology (just to name a few).

In this case, Suh says, the research lent itself to “unexpected challenges” that required intriguing adaptations “at every corner.” But, ultimately, it led to breakthroughs not previously seen in the wearable technology industry, attracting interest from other researchers outside the university, and private companies, too.

“This project was quite exploratory by nature as there hasn’t been any prior research aiming to the same objectives,” Suh says.

Meanwhile, the team has completed durability and reliability testing on its textile-integrated wearable connectors. Eventually, the group would like to increase the sample size for testing to strengthen and validate the findings. The team also hopes to evaluate new, innovative interconnective techniques, as well as other 3D printing techniques and materials as they work to further advance wearable technologies.

DITF: Newly developed concept for chemical protective suits

A newly developed concept for chemical protective suits is designed to make use more comfortable and safer for the user. New materials and an improved design increase wearer comfort. The integration of sensor technology enables the monitoring of vital functions.

In the event of hazards from chemical, biological or radioactive substances, chemical protective suits (CSA) protect people from physical contact. CSAs consist of breathing apparatus, head protection, carrying frames and the suit itself. This adds up to a weight of around 25 kg. The construction of a multi-coated fabric makes the CSA stiff and provides for considerable restrictions in freedom of movement. As a result, the emergency forces are exposed to significant physical stress. For this reason, the total deployment time when using a CSA is limited to 30 minutes.

The construction of a multi-coated fabric makes the CSA stiff and provides for considerable restrictions in freedom of movement. As a result, the emergency forces are exposed to significant physical stress. For this reason, the total deployment time when using a CSA is limited to 30 minutes.

In a joint project with various companies, institutes and professional fire departments, work is currently underway to completely redesign both the textile material composite and the hard components and connecting elements between the two. The goal is a so-called "AgiCSA", which offers significantly more comfort for the emergency forces due to its lighter and more flexible construction. The DITF subproject focuses on the development of a more individually adaptable, body-hugging suit on the one hand, and on the integration of sensors that serve the online monitoring of important body functions of the emergency personnel on the other.

At the beginning of the project, the DITF received support from the Esslingen Fire Department. They provided a complete CSA that is used as standard today. This could be tested at the DITF for its wearing properties. The researchers in Denkendorf are investigating where there is a need for optimization to improve ergonomic wearing comfort.

The aim is to construct a chemical- and gas-tight suit that fits relatively closely to the body. It quickly became clear that it was necessary to move away from the previous concept of using woven fabrics as the basic textile material and think in terms of elastic knitted fabrics. In implementing this idea, the researchers were helped by recent developments in the field of knitted fabric technology in the form of spacer fabrics. By using spacer textiles, many of the requirements placed on the base substrate can be met very well.

Spacer textiles have a voluminous, elastic structure. From a wide range of usable fiber types and three-dimensional design features, a 3 mm thick spacer textile made of a polyester pile yarn and a flame-retardant fiber blend of aramid and viscose was selected for the new CSA. This textile is coated on both sides with fluorinated or butyl rubber. This gives the textile a barrier function that prevents the penetration of toxic liquids and gases. The coating is applied to the finished suit by a newly developed spraying process. The advantage of this process over the conventional coating process is that the desired elasticity of the suit is retained.

Another innovation is the integration of a diagonal zipper. This makes it easier to put on and take off the suit. Whereas this was previously only possible with the help of another person, the new suit can in principle be put on by the emergency responder alone. The new design is modeled on modern dry suits with diagonal, gas-tight zippers.
The new AgiSCA also features integrated sensors that allow the transmission and monitoring of the vital and environmental data of the emergency worker as well as their location via GPS data. These additional functions significantly enhance operational safety.

For the hard components, i.e. the helmet and the backpack for the compressed air supply, lightweight carbon fiber-reinforced composite materials from Wings and More GmbH & Co. KG are used.
The first demonstrators are available and are available to the project partners for testing purposes. The combination of current textile technology, lightweight construction concepts and IT integration in textiles has led to a comprehensive improvement of a high-tech product in this project.
 
BMBF project "Development of a chemical protection suit with increased mobility for more efficient operational concepts through increased autonomy of the emergency forces (AgiCSA)".
The project addresses the objectives of the Federal Government's framework program "Research for Civil Security 2018-2023 and the funding measure "SME-innovative: Research for Civil Security" of July 3, 2018.

The impact of textile production and waste on the environment

  • With fast fashion, the quantity of clothes produced and thrown away has boomed.

Fast fashion is the constant provision of new styles at very low prices. To tackle the impact on the environment, the EU wants to reduce textile waste and increase the life cycle and recycling of textiles. This is part of the plan to achieve a circular economy by 2050.

Overconsumption of natural resources
It takes a lot of water to produce textile, plus land to grow cotton and other fibres. It is estimated that the global textile and clothing industry used 79 billion cubic metres of water in 2015, while the needs of the EU's whole economy amounted to 266 billion cubic metres in 2017.

To make a single cotton t-shirt, 2,700 litres of fresh water are required according to estimates, enough to meet one person’s drinking needs for 2.5 years.

To make a single cotton t-shirt, 2,700 litres of fresh water are required according to estimates, enough to meet one person’s drinking needs for 2.5 years.

The textile sector was the third largest source of water degradation and land use in 2020. In that year, it took on average nine cubic metres of water, 400 square metres of land and 391 kilogrammes (kg) of raw materials to provide clothes and shoes for each EU citizen.

Water pollution
Textile production is estimated to be responsible for about 20% of global clean water pollution from dyeing and finishing products.

Laundering synthetic clothes accounts for 35% of primary microplastics released into the environment. A single laundry load of polyester clothes can discharge 700,000 microplastic fibres that can end up in the food chain.

The majority of microplastics from textiles are released during the first few washes. Fast fashion is based on mass production, low prices and high sales volumes that promotes many first washes.

Washing synthetic products has caused more than 14 million tonnes of microplastics to accumulate on the bottom of the oceans. In addition to this global problem, the pollution generated by garment production has a devastating impact on the health of local people, animals and ecosystems where the factories are located.

Greenhouse gas emissions
The fashion industry is estimated to be responsible for 10% of global carbon emissions – more than international flights and maritime shipping combined.

According to the European Environment Agency, textile purchases in the EU in 2020 generated about 270 kg of CO2 emissions per person. That means textile products consumed in the EU generated greenhouse gas emissions of 121 million tonnes.

Textile waste in landfills and low recycling rates
The way people get rid of unwanted clothes has also changed, with items being thrown away rather than donated. Less than half of used clothes are collected for reuse or recycling, and only 1% of used clothes are recycled into new clothes, since technologies that would enable clothes to be recycled into virgin fibres are only now starting to emerge.

Between 2000 and 2015, clothing production doubled, while the average use of an item of clothing has decreased.

Europeans use nearly 26 kilos of textiles and discard about 11 kilos of them every year. Used clothes can be exported outside the EU, but are mostly (87%) incinerated or landfilled.

The rise of fast fashion has been crucial in the increase in consumption, driven partly by social media and the industry bringing fashion trends to more consumers at a faster pace than in the past.

The new strategies to tackle this issue include developing new business models for clothing rental, designing products in a way that would make re-use and recycling easier (circular fashion), convincing consumers to buy fewer clothes of better quality (slow fashion) and generally steering consumer behaviour towards more sustainable options.

Work in progress: the EU strategy for sustainable and circular textiles
As part of the circular economy action plan, the European Commission presented in March 2022 a new strategy to make textiles more durable, repairable, reusable and recyclable, tackle fast fashion and stimulate innovation within the sector.

The new strategy includes new ecodesign requirements for textiles, clearer information, a Digital Product Passport and calls companies to take responsibility and act to minimise their carbon and environmental footprints

On 1 June 2023, MEPs set out proposals for tougher EU measures to halt the excessive production and consumption of textiles. Parliament’s report calls for textiles to be produced respecting human, social and labour rights, as well as the environment and animal welfare.

Existing EU measures to tackle textile waste
Under the waste directive approved by the Parliament in 2018, EU countries are obliged to collect textiles separately by 2025. The new Commission strategy also includes measures to, tackle the presence of hazardous chemicals, calls producers have to take responsibility for their products along the value chain, including when they become wasteand help consumers to choose sustainable textiles.

The EU has an EU Ecolabel that producers respecting ecological criteria can apply to items, ensuring a limited use of harmful substances and reduced water and air pollution.

The EU has also introduced some measures to mitigate the impact of textile waste on the environment. Horizon 2020 funds Resyntex, a project using chemical recycling, which could provide a circular economy business model for the textile industry.

A more sustainable model of textile production also has the potential to boost the economy. "Europe finds itself in an unprecedented health and economic crisis, revealing the fragility of our global supply chains," said lead MEP Huitema. "Stimulating new innovative business models will in turn create new economic growth and the job opportunities Europe will need to recover."

Interview on the trade fair landscape for floor coverings in Germany

The effects of the Corona pandemic were felt in almost all areas of social and economic life. The trade fair industry in particular was severely affected, with many events cancelled or postponed. With the return to normality, the question arises as to what significance leading trade fairs will have in the post-Corona era and how the competition between different organisers will develop.

Interview on the trade fair landscape for floor coverings in Germany

The effects of the Corona pandemic were felt in almost all areas of social and economic life. The trade fair industry in particular was severely affected, with many events cancelled or postponed. With the return to normality, the question arises as to what significance leading trade fairs will have in the post-Corona era and how the competition between different organisers will develop. For its KLARTEXT interview series, Textination talked to Ms Sonia Wedell-Castellano, Global Director of DOMOTEX Events.

 

After DOMOTEX was unable to take place in 2021 and 2022 due to the pandemic, the trade fair returned in 2023 with a successful event. Nevertheless, the number of exhibitors has almost halved compared to 2020. How do you assess the future importance of leading trade fairs after the industry had to come to terms with online meetings and travel restrictions for a long period of time?

I think it is important to remember that this was the first DOMOTEX since the outbreak of the pandemic, and at a time when the global economic situation is rather difficult. Of course, this situation has made some companies reluctant to participate in DOMOTEX 2023, so we have not yet been able to welcome all companies back as exhibitors at the show. In addition, there were still significant travel restrictions in place at the beginning of the year, for example in China, which simply made it more difficult for our exhibitors to participate in a trade fair abroad. As far as our expectations for the next event are concerned, I can say that many companies - even those that did not exhibit this year - have communicated their interest in wanting to be back at DOMOTEX 2024.
 
We are certain that leading trade fairs and exhibitions in general will continue to be of great importance in the future! You may be able to cultivate existing customers at digital events, but you can't generate new ones. The focus of DOMOTEX is on products you can touch, on the haptic experience on site. You can't transfer that to the digital world. Even the chance encounters at the stand or in the halls do not happen digitally. But a trade fair thrives on personal encounters, personal exchanges. Business is done between people, not between screens. Both exhibitors and visitors have told us quite clearly that they want and need DOMOTEX to be a trade fair where people are present.

 

The degree of internationalisation among DOMOTEX visitors was between 62 and 67 percent in the last three years of the event before the pandemic; in 2023 it even reached 69 percent. Would you agree that leading international trade fairs in Germany are now primarily only important for export-oriented companies? And what does that imply for the economic efficiency of trade fairs?

Certainly, leading international trade fairs in Germany are particularly interesting for export-oriented companies, but not exclusively. That doesn't change anything at all about the profitability of trade fairs. We generate our turnover with all our exhibitors, regardless of whether they are export-oriented or only interested in the Germany-Austria-Switzerland region. That's why satisfied exhibitors are very important to us. And an exhibitor is satisfied when he can do good business or make good contacts at our fairs. It's more and more about the right quality of visitors, less about the quantity. In any case, all our exhibitors very much welcome international visitors!

 

For the 2024 edition, Deutsche Messe has announced that its DOMOTEX concept has been changed to focus on different areas each year: Carpet & Rugs in the odd-numbered years and Flooring in the even-numbered years. Flooring covers wood and laminate flooring, parquet, design flooring, resilient floor coverings, carpets, outdoor flooring and application and installation technology. Carpet & Rugs stands for hand-made carpets and runners as well as for machine-woven carpets.

Yet you say that the Carpet & Rugs segment in particular needs an annual presentation platform, while the flooring segment would like to see DOMOTEX every two years as the central platform for the industry due to longer innovation cycles. Doesn't that actually mean that floor coverings are only in Hannover every other year, but carpets continue to exhibit annually in Hannover? Could you clarify that?

DOMOTEX - Home of Flooring will take place in 2024 and in all even years: This is a DOMOTEX with all exhibitors as we know them from the past. So, from herringbone parquet to outdoor coverings, oriental carpets and contemporary designs - everything, under one roof. In the odd years, i.e. from 2025, there will then be DOMOTEX - Home of Carpets and Rugs, with a focus on suppliers of fitted carpets. The background to this is that the hard flooring industry had wanted DOMOTEX to be held every two years. After this year's DOMOTEX, the suppliers of wall-to-wall carpets have again clearly spoken out in favour of an annual platform. With our new focus model, we are meeting the needs that the market has expressed to us.

 

Messe Frankfurt has declared a new product segment for next year's Heimtextil - interestingly, under the name Carpets & Rugs. While the watchword at DOMOTEX in the even year 2024 is Flooring, Heimtextil offers an alternative trade fair venue for carpets. How do you assess this situation - do exhibitors now have to choose between Hannover and Frankfurt and what does this mean for the split concept?

No, exhibitors from the carpet sector will not have to choose between Hannover and Frankfurt in future - because DOMOTEX is and will remain the home of the entire industry, even in the even years! At DOMOTEX, Home of Flooring means, as I explained earlier, that we present the entire spectrum of floor coverings and carpets. But what is even more important is that we have been told by exhibitors and many visitors that the market does not want to be split up any further. Through the many (small) events, the flooring industry is only competing with itself. To put it bluntly: if only some of the exhibitors take part in ten events, it can't really work. The critical mass is missing. A trade fair is only as good as its participants and they often don't have the time to visit several events.    

 

Another innovation for DOMOTEX is the country focus. What do you expect from this and why did you choose "Insight Italy" for 2024?

With our new special presentation, we want to arouse the curiosity of our visitors - especially retailers, architects and contractors - and highlight the international character of DOMOTEX. After all, what could be more exciting than getting to know a country in depth?  

That is why the INSIGHT concept will in future feature a different country at each DOMOTEX - Home of Flooring. Special exhibition areas will showcase innovations and products, present partnerships with designers and universities, and stage trends. In addition, the conference will provide insights into the respective market and references.  
In 2024, we will start with Italy, a very design-savvy and creative country from which many trends come.

 

Deutsche Messe wants to strengthen the Hannover venue for the leading trade fair DOMOTEX and to hold additional fairs only in Shanghai and in Gaziantep. There will be no Carpet Expo in Istanbul. What influence does the changing entrepreneurial landscape in terms of production countries and markets have on your international concept?

First of all, it must be noted that the business landscape for carpets has not changed in Turkey. Here, only the associations have decided to organise a carpet fair in Istanbul in the future. The background is the continuing visa problem for Turkish exhibitors in Germany as well as the immensely high inflation in Turkey, which makes foreign participation extremely costly for Turkish companies. We would have liked to organise a carpet fair in Istanbul together with the Turkish associations, but not at any price and not on their terms alone. Hannover is and will remain the international platform for DOMOTEX, and we will continue to strengthen this location.

But of course, we also keep an eye on the global market and keep our eyes and ears open at all times, for all our brands, by the way. It was only in this way that DOMOTEX asia/Chinafloor in Shanghai was able to develop into what is now a very successful event. The potential was there, we were in the right place at the right time. If we hadn't seized the opportunity at the time, there would still be a strong floor coverings trade fair in Shanghai - but it would be run by one of our competitors and it wouldn't be called DOMOTEX today.

Many thanks to Ms Sonia Wedell-Castellano for the KLARTEXT.

Cheaper method for making woven displays and smart fabrics

Researchers have developed next-generation smart textiles – incorporating LEDs, sensors, energy harvesting, and storage – that can be produced inexpensively, in any shape or size, using conventional industrial looms used to make the clothing worn every day.
 
An international team, led by the University of Cambridge, have previously demonstrated that woven displays can be made at large sizes, but these earlier examples were made using specialised manual laboratory equipment. Other smart textiles can be manufactured in specialised microelectronic fabrication facilities, but these are highly expensive and produce large volumes of waste.

Researchers have developed next-generation smart textiles – incorporating LEDs, sensors, energy harvesting, and storage – that can be produced inexpensively, in any shape or size, using conventional industrial looms used to make the clothing worn every day.
 
An international team, led by the University of Cambridge, have previously demonstrated that woven displays can be made at large sizes, but these earlier examples were made using specialised manual laboratory equipment. Other smart textiles can be manufactured in specialised microelectronic fabrication facilities, but these are highly expensive and produce large volumes of waste.

However, the team found that flexible displays and smart fabrics can be made much more cheaply, and more sustainably, by weaving electronic, optoelectronic, sensing and energy fibre components on the same industrial looms used to make conventional textiles. Their results, reported in the journal Science Advances, demonstrate how smart textiles could be an alternative to larger electronics in sectors including automotive, electronics, fashion and construction.

Despite recent progress in the development of smart textiles, their functionality, dimensions and shapes have been limited by current manufacturing processes.
“We could make these textiles in specialised microelectronics facilities, but these require billions of pounds of investment,” said Dr Sanghyo Lee from Cambridge’s Department of Engineering, the paper’s first author. “In addition, manufacturing smart textiles in this way is highly limited, since everything has to be made on the same rigid wafers used to make integrated circuits, so the maximum size we can get is about 30 centimetres in diameter.”

“Smart textiles have also been limited by their lack of practicality,” said Dr Luigi Occhipinti, also from the Department of Engineering, who co-led the research. “You think of the sort of bending, stretching and folding that normal fabrics have to withstand, and it’s been a challenge to incorporate that same durability into smart textiles.”
Last year, some of the same researchers showed that if the fibres used in smart textiles were coated with materials that can withstand stretching, they could be compatible with conventional weaving processes. Using this technique, they produced a 46-inch woven demonstrator display.

Now, the researchers have shown that smart textiles can be made using automated processes, with no limits on their size or shape. Multiple types of fibre devices, including energy storage devices, light-emitting diodes, and transistors were fabricated, encapsulated, and mixed with conventional fibres, either synthetic or natural, to build smart textiles by automated weaving. The fibre devices were interconnected by an automated laser welding method with electrically conductive adhesive.
 
The processes were all optimised to minimise damage to the electronic components, which in turn made the smart textiles durable enough to withstand the stretching of an industrial weaving machine. The encapsulation method was developed to consider the functionality of the fibre devices, and the mechanical force and thermal energy were investigated systematically to achieve automated weaving and laser-based interconnection, respectively.

The research team, working in partnership with textile manufacturers, were able to produce test patches of smart textiles of roughly 50x50 centimetres, although this can be scaled up to larger dimensions and produced in large volumes.
 
“These companies have well-established manufacturing lines with high throughput fibre extruders and large weaving machines that can weave a metre square of textiles automatically,” said Lee. “So when we introduce the smart fibres to the process, the result is basically an electronic system that is manufactured exactly the same way other textiles are manufactured.”
The researchers say it could be possible for large, flexible displays and monitors to be made on industrial looms, rather than in specialised electronics manufacturing facilities, which would make them far cheaper to produce. Further optimisation of the process is needed, however.

“The flexibility of these textiles is absolutely amazing,” said Occhipinti. “Not just in terms of their mechanical flexibility, but the flexibility of the approach, and to deploy sustainable and eco-friendly electronics manufacturing platforms that contribute to the reduction of carbon emissions and enable real applications of smart textiles in buildings, car interiors and clothing. Our approach is quite unique in that way.”

The research was supported in part by the European Union and UK Research and Innovation.

  • General economic developments are dampening mood in composites industry
  • Future expectations are optimistic
  • Investment climate has remained stable
  • Varying expectations for application industries
  • Growth drivers have remained unchanged
  • Composites Index is pointing in different directions

This is the 20th time that Composites Germany has identified the latest performance indicators for the fibre-reinforced plastics market. The survey covered all the member companies of the umbrella organisations of Composites Germany: AVK and Composites United, as well as the associated partner VDMA.  

General economic developments are dampening mood in composite industry
Like all industries, the composite industry has been affected by strong negative forces in recent years. The main challenges over the last few years have been the Covid pandemic, a shortage of semiconductors, supply chain problems and a sharp rise in the price of raw materials. Furthermore, there have been numerous isolated effects that added to the pressure on the industry.

The main challenges during the past year were primarily a steep increase in energy and fuel prices and the cost of logistics. In addition, the war in Ukraine put a further strain on supply chains that had already been weakened.

Overall, the stock market prices for both electricity and petroleum products are currently showing a clear downward trend. However, the significantly lower prices have not yet percolated from manufacturers and buyers to the end customer.

The aforementioned effects have further dampened the mood in the composites industry. The index assessing the current general business situation in Germany and Europe has dropped even further than before. However, the assessment of the global situation is somewhat more positive.

Despite this generally negative assessment of the current situation, companies are moving in a somewhat more positive direction in the assessment of their own business situations. The companies that were surveyed rated their own positions more positively than in the last survey.

Future expectations are optimistic
The expectations on future market developments are showing a very positive picture. After a significant drop in the last survey, the indicators for the general business situation are now displaying a clear upward trend again. Moreover, respondents were far more optimistic about their own companies’ future prospects.

Investment climate remaining stable
The investment climate has remained at a stable level. Nearly half of the companies surveyed are planning to employ new staff over the next six months. As before, about 70% of respondents are either considering or planning machine investments. Unlike in the previous survey, this value has remained almost unchanged.

Varying expectations for application industries
The composites market is highly heterogeneous in terms of both materials and applications. In the survey, respondents were asked to assess the market developments of different core areas. Expectations turned out to be extremely diverse.

The most important application segment for composites is the transport sector. The number of new registrations of passenger cars has been declining in recent years. This is where we can see OEMs moving away from volume models and opting for more profitable mid-range and premium segments. In this year’s survey, this shows itself in relatively cautious expectations for this segment.

The currently rather pessimistic outlook for the construction industry is leading companies to expect major slumps in this sector, in particular. The building sector, in particular, often reacts rather slowly to short-term economic fluctuations and has long been relatively robust towards the aforementioned crises. Now, however, it seems that this area, too, is being affected by negative influences.

The pessimistic outlook on the sports and leisure sector can be explained by a rather pessimistic view of consumer behaviour.

Expectations about future market developments, on the other hand, are significantly more positive than the figures presented here might suggest.

Growth drivers still stable
As before, the current survey shows Germany, Europe and Asia as the global regions expected to deliver the most important growth stimuli for the composites segment, with Europe playing a key role for many of the respondents.

Where materials are concerned, we are seeing a continuation of the ongoing paradigm shift. Whereas, in the first 13 surveys, respondents always believed that the composites segment would receive its prevailing growth stimuli from CRP, there is now an almost universal expectation that the most important stimuli will be coming from GRP or from all the materials.

Composites Index points in different directions
Despite the many negative influences that have occurred recently, composites appear to be in good shape for the future. Thanks to excellent market developments in 2021, they have almost reached their pre-pandemic level. The outlook for market developments in 2022 have not been finalised but are showing a less positive trend for last year.

Nevertheless, there are many indications to suggest that the generally positive development of the composite industry over the last few years is set to continue. In the medium term, structural changes in the transport sector will open up opportunities for composites to gain a new foothold in new applications. Major opportunities can be seen in areas of construction and infrastructure. Despite the rather weak market situation, these areas offer enormous opportunities for composites, due to their unique properties which predestine them for long-term use. The main assets of these materials are their durability, their almost maintenance-free use, their potential for use in lightweight construction and their positive impact on sustainability. Furthermore, one major growth driver is likely to be the wind industry, provided that it meets the politically self-imposed targets for the share of renewable energies in power consumption.

Overall, the Composites Index shows a restrained assessment of the current situation, whereas the assessment of the future situation is clearly positive. Respondents are apparently optimistic about the future, reflecting the assessment mentioned above: Composites have been used in industry and in serial production for several decades and, despite numerous challenges, they are set to provide immense potential for exploring new areas of application.

The next Composites Market Survey will be published in July 2023.

6 out of 10 consumers pay attention to sustainability criteria when shopping

ESG aspects are most important to consumers when it comes to food and clothing. Young people in particular demand information and transparency: sustainability labels, certifications and reports ensure trust. For retailers and manufacturers, sustainability is becoming a must.

Under what conditions are the cows kept whose milk I drink? Does the manufacturer of my new T-shirt tolerate child labor? Does the retailer I trust deal fairly with employees and business partners? The majority of Germans ask themselves questions like these before making a purchasing decision. When shopping, 59 percent of consumers always or at least frequently pay attention to the ecological, economic or social sustainability of retailers and manufacturers. Among those under 35, the figure is even hugher with two-thirds, and among those over 55, one in two. These are the findings of a representative survey of 1,000 people in Germany commissioned by the auditing and consulting firm PwC Germany.

ESG aspects are most important to consumers when it comes to food and clothing. Young people in particular demand information and transparency: sustainability labels, certifications and reports ensure trust. For retailers and manufacturers, sustainability is becoming a must.

When shopping, 59 percent of consumers always or at least frequently pay attention to the ecological, economic or social sustainability of retailers and manufacturers. Among those under 35, the figure is even hugher with two-thirds, and among those over 55, one in two. These are the findings of a representative survey of 1,000 people in Germany commissioned by the auditing and consulting firm PwC Germany.

Sustainability is no longer a question of "if", but "how".
"Sustainability has become mainstream in recent years. For companies, paying attention to sustainability in their supply chains has already become a must," comments Dr. Christian Wulff. The Head of Retail and Consumer Goods at PwC Germany is convinced that companies will already have to give good reasons in the near future if they do not pay attention to the environment, social aspects and good corporate governance when producing a product. "The issue of sustainability is therefore no longer a question of whether, but of how," the retail expert continues.

Sustainability includes various aspects in the three areas of environment, social and sustainable governance (ESG). In the case of environmental sustainability, the focus is on issues relating to animal welfare - such as the conditions in which animals are kept or animal testing - and the use of recyclable materials. 40 percent of Germans would like to be informed about this before making a purchase. In the social sphere, the majority of respondents would like to know whether retailers and manufacturers comply with human rights (58 percent) - for example, whether they tolerate forced or child labor in their value chains. In terms of governance, one in two respondents would like to know about supply chains and be able to trace products before making a purchase.

Sustainability is particularly important for food
How closely consumers look at sustainability also depends on the product: For example, sustainability is particularly important to them when it comes to food. 81 percent of Germans pay attention to at least one of the three ESG criteria when buying food, i.e. environment, social issues or good corporate governance. But these criteria are also relevant when buying textiles: As many as 63 percent say they look at how sustainably the item was produced when buying clothing or shoes. While environmental aspects play the biggest role for food (62 percent), consumers are paying more attention to social aspects for clothing, shoes and accessories (52 percent).

Almost every second person has recently switched to sustainable products
The growing importance of ESG aspects in the purchasing behavior of German consumers is also evidenced by the shifts toward buying sustainable products. The trend toward sustainable products is clearest in the case of food: 45 percent of respondents state that they have consciously switched to more sustainable products within the past two years. By contrast, only 17 percent admit to switching (back) to less sustainable products, with one in three stating a lack of financial resources as the reason.

For just under half of those surveyed, a possible switch to more sustainable products would be supported by better availability in stationary retail. Legal regulations are also seen as helpful, both in terms of product labeling (38 percent) and for the production process (37 percent). More eye-catching product placement in stores would also help (37 percent).

Young people in particular demand transparency and education
Consumers' need for transparency in ESG matters is significant: According to the survey, almost three quarters of Germans obtain information about environmental sustainability issues at least occasionally. Two-thirds research aspects of social sustainability. A good half regularly find out about sustainable corporate governance.

Age has a major influence on how intensively people deal with the issue: While 80 percent of 16- to 24-year-olds find out about the environmental aspects of a product before buying it, only 59 percent of those over 65 do. "Younger people in particular are actively informing themselves and demanding transparency around ESG criteria," sums up Christian Wulff.

Consumers want information on packaging and online
To meet this need for information, the PwC expert advises manufacturers and retailers to provide detailed information about ESG aspects of products, especially online. "Keeping the associated, significantly increasing flood of data up to date at all times is increasingly becoming a challenge for companies that can only be solved by significant investments in new technologies."

Consumers agree on what companies can do to lend more credibility to their sustainability activities: A solid two-thirds consider recognized sustainability labels, certifications or independently audited sustainability reports to be suitable for credibly communicating activities in terms of ESG. "The results of our survey show that labels and independent certifications are very important in gaining the trust of customers. It is therefore worthwhile to have ESG measures confirmed by external organizations," says Christian Wulff.

Retailers and manufacturers should focus on transparency
"Manufacturers and retailers are faced with the task of ensuring a high level of transparency with regard to the sustainability of their products. This calls for honesty, but also creativity: In the case of fashion, for example, it is conceivable to trace the individual stages of the supply chain in detail and to show the costs incurred in the process. In this way, consumers can understand exactly how a price comes about," concludes Christian Wulff.

... and they actually can be recycled: Wind Turbine Blades

The Danish company Continuum Group ApS with its subsidiary companies in Denmark (Continuum Aps) and the UK (Continuum Composite Transformation (UK) Limited) wants to give end-of-life wind blades and composites a new purpose, preventing them going to waste. The goal is to reduce the amounts of CO2 emitted to the atmosphere by the current waste streams, delivering a value to Europe’s Net Zero efforts.

Continuum states that it ensures all wind turbine blades are 100% recyclable and plans to build industrial scale recycling factories across Europe.

Net zero is the phrase on everyone’s lips, and as 2030 rapidly approaches we constantly hear updates about wind energy generating renewable energy that powers millions of European homes – but what happens when those turbine blades reach the end of their lifespan?

Net zero is the phrase on everyone’s lips, and as 2030 rapidly approaches we constantly hear updates about wind energy generating renewable energy that powers millions of European homes – but what happens when those turbine blades reach the end of their lifespan?

Currently the general answer is to put them into landfill or co-process them into cement, but neither is planet friendly. Many countries in Europe look to ban landfill from 2025, so this option is likely to be eliminated in the near future.

Continuum provides an alternative: When the end of their first life arrives, Continuum recycles them into new, high performing composite panels for the construction, and related industries. The vision of the Danes: Abandon the current landfilling, and drastically reduce CO2 emitted during currently applied incineration & co-processing in cement factories by 100 million tons by 2050, via their mechanical composite recycling technology and their industrial scale factories.  

The technology is proven, patented, and ready to go, says Reinhard Kessing, co-founder and CTO of Continuum Group ApS, who has spent more than 20 years of research and development in this field, and advanced the reclamation of raw materials from wind blades and other composite products and transformation of these materials into new, high performing panel products.

By working with partners, Continuum’s cost-effective solution covers end-to-end logistics and processes. This spans from the collection of the end-of-life blades through to the reclamation of the pure clean raw materials and then the remanufacturing of all those materials into high value, highly performing, infinitely recyclable composite panels for the construction industry or the manufacture of many day-to-day products such as facades, industrial doors, and kitchen countertops. The panels are 92% recycled blade material and are said to outperform competing products.

Nicolas Derrien: Chief Executive Officer of Continuum Group ApS said: “We need solutions for the disposal of wind turbine blades in an environmentally friendly manner, we need it now, and we need it fast, and this is where Continuum comes in! As a society we are rightly focussed on renewable energy production, however the subject of what to do with wind turbine blades in the aftermath of that production has not been effectively addressed. We’re changing that, offering a recycling solution for the blades and a construction product that will outperform most other existing construction materials and be infinitely recyclable, and with the lowest carbon footprint in its class.”

Martin Dronfield, Chief Commercial Officer of Continuum Group ApS and Managing Director of Continuum Composite Transformation (UK) Ltd, adds: “We need wind energy operators & developers across Europe to take a step back and work with us to solve the bigger picture challenge. Continuum is offering them a service which won’t just give their business complete and sustainable circularity to their operations but help protect the planet in the process.“

Each Continuum factory in Europe will have the capacity to recycle a minimum of 36,000 tons of end-of-life turbine blades per year and feed the high value infinitely recyclable product back into the circular economy by 2024/25.

Due to an investment by Climentum Capital and a grant from the UK’s ‘Offshore Wind Growth Partnership’, Continuum are planning for the first of six factories in Esbjerg to be operational by the end of 2024 and for a second factory in the United Kingdom to follow on just behind it. After that they are looking to build another four in France, Germany, Spain, and Turkey by 2030.

As part of their own pledge to promote green behaviour, Continuum have designed their factories to be powered by only 100% green energy and to be zero carbon emitting environments; meaning no emissions to air, no waste fluids to ground, and no carbon fuel combustion.

Fraunhofer: Optimized production of nonwoven masks

Producing infection control clothing requires a lot of energy and uses lots of material resources. Fraunhofer researchers have now developed a technology which helps to save materials and energy when producing nonwovens. A digital twin controls key manufacturing process parameters on the basis of mathematical modeling. As well as improving mask manufacturing, the ProQuIV solution can also be used to optimize the production parameters for other applications involving these versatile technical textiles, enabling manufacturers to respond flexibly to customer requests and changes in the market.

A digital twin controls key manufacturing process parameters on the basis of mathematical modeling. As well as improving mask manufacturing, the ProQuIV solution can also be used to optimize the production parameters for other applications involving these versatile technical textiles, enabling manufacturers to respond flexibly to customer requests and changes in the market.

Nonwoven infection control masks were being used in their millions even before the COVID-19 pandemic and are regarded as simple mass-produced items. Nevertheless, the manufacturing process used to make them needs to meet strict requirements regarding precision and reliability. According to DIN (the German Institute for Standardization), the nonwoven in the mask must filter out at least 94 percent of the aerosols in the case of the FFP-2 mask and 99 percent in the case of the FFP-3 version. At the same time, the mask must let enough air through to ensure that the wearer can still breathe properly. Many manufacturers are looking for ways to optimize the manufacturing process. Furthermore, production needs to be made more flexible so that companies are able to process and deliver versatile nonwovens for a wide range of different applications and sectors.

ProQuIV, the solution developed by the Fraunhofer Institute for Industrial Mathematics ITWM in Kaiserslautern, fulfills both of these aims. The abbreviation “ProQuIV” stands for “Production and Quality Optimization of Nonwoven Infection Control Clothing” (Produktions- und Qualitätsoptimierung von Infektionsschutzkleidung aus Vliesstoffen). The basic idea is that manufacturing process parameters are characterized with regard to their impact on the uniformity of the nonwoven, and this impact is then linked to properties of the end product; for example, a protective mask. This model chain links all relevant parameters to an image analysis and creates a digital twin of the production process. The digital twin enables real-time monitoring and automatic control of nonwoven manufacturing and thus makes it possible to harness potential for optimization.

Dr. Ralf Kirsch, who works in the Flow and Material Simulation department and heads up the Filtration and Separation team, explains: “With ProQuIV, the manufacturers need less material overall, and they save energy. And the quality of the end product is guaranteed at all times.”

Nonwoven manufacturing with heat and air flow
Nonwovens for filtration applications are manufactured in what is known as the
meltblown process. This involves melting down plastics such as polypropylene and forcing them through nozzles so they come out in the form of threads referred to as filaments. The filaments are picked up on two sides by air flows which carry them forward almost at the speed of sound and swirl them around before depositing them on a collection belt. This makes the filaments even thinner: By the end of the process, their thickness is in the micrometer or even submicrometer range. They are then cooled, and binding agents are added in order to create the nonwoven. The more effectively the temperature, air speed and belt speed are coordinated with each other, the more uniform the distribution of the fibers at the end and therefore the more homogeneous the material will appear when examined under a transmitted light microscope. Lighter and darker areas can thereby be identified — this is referred to by experts as cloudiness. The Fraunhofer team has developed a method to measure a cloudiness index on the basis of image data. The light areas have a low fiber volume ratio, which means that they are less dense and have a lower filtration rate. Darker areas have a higher fiber volume and therefore a higher filtration rate. On the other hand, the higher air flow resistance in these areas means that they filter a smaller proportion of the air that is breathed in. A larger proportion of the air flows through the more open areas which have a less effective filtration effect.

Production process with real-time control
In the case of ProQuIV, the transmitted light images from the microscope are used to calibrate the models prior to use. The experts analyze the current condition of the textile sample and use this information to draw conclusions about how to optimize the system — for example, by increasing the temperature, reducing the belt speed or adjusting the strength of the air flows. “One of the key aims of our research project was to link central parameters such as filtration rate, flow resistance and cloudiness of a material with each other and to use this basis to generate a method which models all of the variables in the production process mathematically,” says Kirsch. The digital twin monitors and controls the ongoing production process in real time. If the system deviates slightly from where it should be — for example, if the temperature is too high — the settings are corrected automatically within seconds.

Fast and efficient manufacturing
“This means that it is not necessary to interrupt production, take material samples and readjust the machines. Once the models have been calibrated, the manufacturer can be confident that the nonwoven coming off the belt complies with the specifications and quality standards,” explains Kirsch. ProQuIV makes production much more efficient — there is less material waste, and the energy consumption is also reduced. Another advantage is that it allows manufacturers to develop new nonwoven-based products quickly — all they have to do is change the target specifications in the modeling and adjust the parameters. This enables production companies to respond flexibly to customer requests or market trends.

This might sound logical but can be quite complex when it comes to development. The way that the values for filtration performance and flow resistance increase, for example, is not linear at all, and they are not proportional to the fiber volume ratio either. This means that doubling the filament density does not result in double the filtration performance and flow resistance — the relationship between the parameters is much more complex than that. “This is precisely why the mathematical modeling is so important. It helps us to understand the complex relationship between the individual process parameters,” says ITWM researcher Kirsch. The researchers are able to draw on their extensive expertise in simulation and modeling for this work.

More applications are possible
The next step for the Fraunhofer team is to reduce the breathing resistance of the nonwovens for the wearer without impairing the protective effect. This is made possible by electrically charging the fibers and employing a principle similar to that of a feather duster. The electric charge causes the textile fabric to attract the tiniest of particles which could otherwise slip through the pores. For this purpose, the strength of the electrostatic charge is integrated into the modeling as a parameter.

The Fraunhofer researchers’ plans for the application of this method extend far beyond masks and air filters. Their technology is generally applicable to the production of nonwovens — for example, it can also be used in materials for the filtration of liquids. Furthermore, ProQuIV methods can be used to optimize the manufacture of nonwovens used in sound-insulating applications.

Circular Economy: It could all be so simple... or not

Interview with Henning Wehland & Robert Kapferer, Circularity Germany

Interview with Henning Wehland & Robert Kapferer, Circularity Germany

I'm a very curious guy by nature. That's why I offered to help out at a well-known hot dog station in Münster (Germany) this year, to draw attention to the shortage of staff in the gastronomy. I wrote an article about it on LinkedIn, which was in turn reacted to by Ines Chucholowius.
From her profile, I could see that she is a consultant for strategic marketing and communication in the textile industry. Not entirely serious, she offered me a job in her office. Like pushing a button, the pictures in my mind set in: Textile industry, exciting! Merchandising, contacts in the industry, collaborations, and I agreed to a short chat, at the end of which we spoke on the phone and arranged to meet.
 
She told me about her website TEXTINATION.de. And we were already involved in an exciting, heated exchange about perception and truth in the textile industry. Without further ado, we left it at that and I went home with a chunk of new information about an exciting field. Our dialogue on social media continued and eventually Ines offered me the chance to feed my die-hard curiosity with the support of TEXTINATION.de. I could write a blog on the site, about people, products, service providers, producers, startups or trends that interest me, to add to my half-knowledge about the textile industry.

Textile waste into the front ... new T-shirt out the back
During this exchange and a long brainstorming session, certain terms kept tickling my attention:
Circular economy, recycling, recyclable material loops. Circular Economy, Recycling, Recyclables. Even though there are many different definitions and some even distinguishing between different aspects: the former thought from waste that flows back into production as a secondary raw material, a more modern approach avoiding waste already in production - the general consensus is really only that circular economy is a cycle in which waste is used as a source for something new.

Sounds like useful additions for all areas of the manufacturing real economy to me. Ines introduced me to Robert Kapferer: He runs a startup called Circularity Germany in Hamburg. His company, founded in 2021 and consisting of Robert and another partner, is an offshoot of the Dutch-based company Circularity B.V. Its founder Han Hamers, with a degree in child psychology and a professional background in the textile dyeing industry, had the idea five years ago for a production facility that spins new yarn exclusively from textile production waste and old textiles turning it into T-shirts, polo shirts and sweatshirts.
Whether this works, and if so, how, is what I wanted to find out, and Ines and I arranged to meet Robert for a 90-minute online conference.

Robert, originally an industrial engineer, comes from a less sustainable industry. He worked for 11 years as managing director for AVECO Material und Service GmbH, where he was responsible for the workwear of more than 50,000 employees.

At the beginning of our conversation, he emphasizes that a moment in January 2021 changed his life and from then on, he wanted to dedicate himself to the topic of circular economy with all his might. That was when he met Han Hamers, who inspired him to found Circularity Germany. His enthusiasm and passion for the subject sound credible, and he begins to describe the differences between chemical and mechanical recycling methods. In summary, the mechanical process of shredding and the subsequent spinning shortens the fibers and thus restricts their properties for further processing. The advantage lies primarily in the comparatively uncomplicated, fast and more cost-efficient process. In the chemical variant, chemical waste remains, but the processed materials are broken down again into their basic building blocks in such a way that they have almost all the same properties as a so-called virgin raw material. Circularity Germany stands for the mechanical process.

And then comes the sentence that gets all our attention: "We've advanced a spinning technology so much that it relies exclusively on waste-based raw materials."
This sentence almost doesn't stand out because Robert still talks - quite excitingly - about the fact that they are planning a production and manufacturing facility where everything from knitting yarn to relatively fine thread can be spun and then further processed into fabric. And here Ines and I ask intensively: Essential requirements for industrial production still seem to be unresolved, and necessary processes are still in the planning stage. For example, the question of whether to work with pre-consumer or post-consumer waste. Pre-consumer waste is cutting waste from the production of clothes, which corresponds to about 10% of the processed material. Post-consumer waste we know as used textiles.

As long as production still takes place in India, Circularity currently uses mainly pre-consumer waste. These come exclusively from sewing factories in the Tirupur region in the south of India. When using used textiles, which exist in large quantities in Germany (according to a study, 28-40% of all garments produced are thrown away unworn), Circularity produces blended yarns of cotton and polyester. The company does not offer pure cotton yarns.

Textiles are treated with chemicals to varying degrees - workwear in particular cannot do without them. The fact that Han Hemers is also collecting used textile stocks from the Dutch army in order to reintroduce them renewed into the consumer cycle is therefore not reassuring. Military clothing has to be finished with all kinds of additives.

Therefor I ask how he can dispel doubts in a consumer’s mind like mine, with a healthy half-knowledge of mask deals and greenwashing, that a well-intentioned vision will be followed by a dark awakening. This concern cannot yet be resolved after the conversation.

We limit ourselves to what is planned: Robert has the dream of reversing the globalized process of textile production. He wants to end the decoupling of cotton growing regions and far-flung production such as Asia with subsequent shipping of ready-made goods to Europe. In the future, existing used textiles and/or cutting wastes are to be collected on site, recycled and processed locally into new textiles.

I believe him in having this dream. However, some of my questions about sustainability remain unanswered - which is why I have my doubts about whether the idea is currently capable of performing and competing.
What are the reasons for this? For one thing, I think it's always difficult to do necessary pioneering work. Especially when listening to smart comments at the regulars' table that large companies are already working intensively on the principle of circular economy. But sometimes, apart from the term "circular economy" and a vague commitment to it, not much remains.

Circularity Germany is committed to developing a technology based exclusively on waste. The interview points out that this also includes making production more environmentally friendly and eliminating transport routes, which further reduces the burden on the environment. When all the requirements for realizing this dream have been met and a product that is competitive in terms of both quality and price can be launched on the market, it is up to the consumer to decide. Here one would have the credible argument of sustainability and a socially and environmentally fair process. Circularity would then not have to worry about PR.

It needs to be given time and, above all, attention. But perhaps the industry should get involved right here and now, and invest in startups like this and make sure that problems are cleared out of the way. Because one thing has become clear to us in this conversation:

It could all be so simple. Circular economy is achievable, but the road there is still costly and rocky. That's why we wish Robert and his team every success and, above all, perseverance. Thank you for the interview.

Wearables for healthcare: sensors to wear

Stylish sensors to wear 
With sensors that measure health parameters and can be worn on the body, we do let technology get very close to us. A collaboration between Empa and designer Laura Deschl, sponsored by the Textile and Design Alliance (TaDA) of Eastern Switzerland, shows that medical monitoring of respiratory activity, for example, can also be very stylish – as a shirt.

A collaboration between Empa and designer Laura Deschl, sponsored by the Textile and Design Alliance (TaDA) of Eastern Switzerland, shows that medical monitoring of respiratory activity, for example, can also be very stylish – as a shirt.

The desire for a healthy lifestyle has triggered a trend towards self-tracking. Vital signs should be available at all times, for example to consistently measure training effects. At the same time, among the continuously growing group of people over 65, the desire to maintain performance into old age is stronger than ever. Preventive, health-maintaining measures must be monitored if they are to achieve the desired results. The search for measurement systems that reliably determine the corresponding health parameters is in full swing. In addition to the leisure sector, medicine needs suitable and reliable measurement systems that enable efficient and effective care for an increasing number of people in hospital and at home. After all, the increase in lifestyle diseases such as diabetes, cardiovascular problems or respiratory diseases is putting a strain on the healthcare system.

Researchers led by Simon Annaheim from Empa's Biomimetic Membranes and Textiles laboratory in St. Gallen are therefore developing sensors for monitoring health status, for example for a diagnostic belt based on flexible sensors with electrically conductive or light-conducting fibers. However, other, less technical properties can be decisive for the acceptance of continuous medical monitoring by patients. For example, the sensors must be comfortable to wear and easy to handle – and ideally also look good.

This aspect is addressed by a cooperation between the Textile and Design Alliance, or TaDA for short, in eastern Switzerland and Empa. The project showed how textile sensors can be integrated into garments. In addition to technical reliability and a high level of comfort, another focus was on the design of the garments. The interdisciplinary TaDA designer Laura Deschl worked electrically conductive fibers into a shirt that change their resistance depending on how much they are stretched. This allows the shirt to monitor how much the subjects' chest and abdomen rise and fall while they breathe, allowing conclusions to be drawn about breathing activity. Continuous monitoring of respiratory activity is of particular interest for patients during the recovery phase after surgery and for patients who are being treated with painkillers. Such a shirt could also be helpful for patients with breathing problems such as sleep apnea or asthma. Moreover, Deschl embroidered electrically conductive fibers from Empa into the shirt, which are needed to connect to the measuring device and were visually integrated into the shirt's design pattern.

The Textile and Design Alliance is a pilot program of the cultural promotion of the cantons of Appenzell Ausserrhoden, St.Gallen and Thurgau to promote cooperation between creative artists from all over the world and the textile industry. Through international calls for proposals, cultural workers from all disciplines are invited to spend three months working in the textile industry in eastern Switzerland. The TaDA network comprises 13 cooperation partners – textile companies, cultural, research and educational institutions – and thus offers the creative artists direct access to highly specialized know-how and technical means of production in order to work, research and experiment on their textile projects on site. This artistic creativity is in turn made available to the partners as innovative potential.

The sixth BMW Group Supplier Innovation Awards were presented at the BMW Welt in Munich on 17 November 2022. The coveted award was presented in a total of six categories: powertrain & e-mobility, sustainability, digitalisation, customer experience, newcomer of the year and exceptional team performance.

Bcomp won the BMW Group Supplier Innovation Award in the Newcomer of the Year category. Following a successful collaboration with BMW M Motorsport for the new BMW M4 GT4 that extensively uses Bcomp’s powerRibs™ and ampliTex™ natural fibre solutions and BMW iVentures recently taking a stake in Bcomp as lead investor in the Series B round, this award is another major step and recognition on the path to decarbonizing mobility.

“Innovations are key to the success of our transformation towards electromobility, digitalisation and sustainability. Our award ceremony recognises innovation and cooperative partnership with our suppliers – especially in challenging times,” said Joachim Post, member of the Board of Management of BMW AG responsible for Purchasing and Supplier Network at the ceremony held at BMW Welt in Munich.

BMW first started to work with Bcomp’s materials in 2019 when they used high-performance natural fibre composites in the BMW iFE.20 Formula E car. From this flax fibre reinforced cooling shaft, the collaboration evolved and soon after, the proprietary ampliTex™ and powerRibs™ natural fibre solutions were found successfully substituting selected carbon fibre components in DTM touring cars from BMW M Motorsport. By trickling down and expanding into other vehicle programs, such developments highlight the vital role that BMW M Motorsports plays as a technology lab for the entire BMW Group. This continues in the form of the latest collaboration with Bcomp to include a higher proportion of renewable raw materials in the successor of the BMW M4 GT4.

With the launch of the new BMW M4 GT4, it will be the serial GT car with the highest proportion of natural fibre components. Bcomp’s ampliTex™ and powerRibs™ flax fibre solutions can be found throughout the interior on the dashboard and centre console, as well as on bodywork components such as the hood, front splitter, doors, trunk, and rear wing. Aside from the roof, there are almost no carbon fibre reinforced plastic (CFRP) components that were not replaced by the renewable high-performance flax materials. “Product sustainability is increasing in importance in the world of motorsport too,” says Franciscus van Meel, Chairman of the Board of Management at BMW M GmbH.

Bcomp is a leading solutions provider for natural fibre reinforcements in high performance applications from race to space.

The company started as a garage project in 2011 with a mission to create lightweight yet high performance skis. The bCores™ were launched and successfully adopted by some of the biggest names in freeride skiing. The founders, material science PhDs from École Polytechnique Fédérale de Lausanne (EPFL), used flax fibres to reinforce the balsa cores and improve shear stiffness. Impressed by the excellent mechanical properties of flax fibres, the development to create sustainable lightweighting solutions for the wider mobility markets started.

Flax is an indigenous plant that grows naturally in Europe and has been part of the agricultural history for centuries. It requires very little water and nutrients to grow successfully. In addition, it acts as a rotational crop, thus enhancing harvests on existing farmland. Neither cultivation nor processing of the flax plants requires any chemicals that could contaminate ground water and harvesting is a completely mechanical process. After harvesting the entire flax plant can be used for feed, to make oil and its fibres are especially used for home textiles and clothing. The long fibre that comes from the flax plant possesses very good mechanical properties and outstanding damping properties in relation to its density, making it especially suited as a natural fibre reinforcement for all kinds of polymers.

The harvesting and processing of flax takes place locally in the rural areas it was grown in. Using European flax sourced through a well-established and transparent supply chain it allows to support the economic and social structure in rural areas thanks to the large and skilled workforce required to sustain the flax production. When it comes to the production of technical products like the powerRibs™ reinforcement grid, Bcomp is investing in local production capacities close to its headquarters in the city of Fribourg, Switzerland, thus creating new jobs and maintaining technical know-how in the area. The production is built to be as efficient as possible and with minimal environmental impact and waste.

Further strengthening the local economy, Bcomp aims to hire local companies for missions and with the headquarters being located in Fribourg’s “Blue Factory” district, Bcomp can both benefit from and contribute to the development of this sustainable and diverse quarter.

Textile Electrodes for Medtech Applications

  • Successful financing round for Empa spin-off Nahtlos

Nahtlos, an Empa spin-off, has received 1 million Swiss francs in a first round of financing from a network of business angels from Switzerland and Liechtenstein and from the Startfeld Foundation. With this funding, Nahtlos aims to drive the market entry of its newly developed textile-based electrode for medical applications.

  • Successful financing round for Empa spin-off Nahtlos

Nahtlos, an Empa spin-off, has received 1 million Swiss francs in a first round of financing from a network of business angels from Switzerland and Liechtenstein and from the Startfeld Foundation. With this funding, Nahtlos aims to drive the market entry of its newly developed textile-based electrode for medical applications.

Over the past two years, Nahtlos, an Empa spin-off, has developed novel textile-based electrodes for recording heart activity (electrocardiogram, ECG) – for example, to detect atrial fibrillation – and for electrostimulation therapies, for example, to preserve the muscle mass in paralyzed patients. Textile-based electrodes enable gentle and skin-friendly application, even if the electrodes have to be worn for several days or even weeks. The textile electrode is thus the first alternative to the gel electrode, which was developed 60 years ago and is still considered the standard for medical applications today.

Nahtlos founder and former Empa researcher Michel Schmid and co-founder and business economist José Näf have further developed the textile-based technology, which was developed and patented at Empa in various projects funded by Innosuisse, among others. The goal was to produce a product for long-term medical applications that reliably records ECG signals for up to several weeks, achieves a high level of patient acceptance and is cost-effective for the healthcare provider. Today, the patent for textile-based electrode technology is owned by Nahtlos after reaching a milestone.

Financing by business angels and Startfeld Foundation
Schmid and Näf were looking for investors to certify their product, set up production and develop the market – and recently found what they were looking for: In a seed financing round, the two young entrepreneurs were able to acquire 1 million Swiss francs from business angels from Switzerland and Liechtenstein as well as from the Startfeld Foundation. Nahtlos was supported in setting up its company by Startfeld, the start-up promotion arm of Switzerland Innovation Park Ost (SIP Ost), in the form of coaching, consulting and early-stage financing. Nahtlos is also based in the Innovation Park Ost, where innovations are initiated and accelerated through collaboration between start-ups, companies, universities and research institutions.

Together with Empa and Nahtlos, SIP Ost was present at OLMA this year. Visitors could learn live and on the spot about Empa's research activities in the field of Digital Health as well as about the Nahtlos technology and its textile electrodes for health monitoring.

Sustainability in 3D Printing: Components made of Natural Fibers

3D printing has been in use in architecture for a while, and now it is to become ecologically sustainable as well: Together with partners, the LZH is researching how to produce individual building elements from natural fibers using additive manufacturing.

3D printing has been in use in architecture for a while, and now it is to become ecologically sustainable as well: Together with partners, the LZH is researching how to produce individual building elements from natural fibers using additive manufacturing.

In the project 3DNaturDruck, architectural components such as facade elements shall be created from natural fiber-reinforced biopolymers in 3D printing. To this end, the scientists will develop the corresponding composite materials from biopolymers with both natural short fibers and natural continuous fibers and optimize them for processing with the additive manufacturing process FDM (Fused Deposition Modeling). The project partners' goal is to enable smart and innovative designs that are both ecological and sustainable.
 
The goal: highly developed components made from sustainable materials
Within the project, different natural fiber-reinforced biopolymer composites will be investigated. The partners are researching both processing methods with very short natural fibers, such as from wood and straw, and a method for printing continuous fibers from hemp and flax in combination with biopolymers. The LZH then develops processes for these new materials and adapts the tools and nozzle geometries of the FDM printer. A pavilion with the 3D-printed facade elements is planned as a demonstrator on the campus of the University of Stuttgart.
 
The project partners want to explore how additive manufacturing can be used to simplify manufacturing processes for architectural components. Natural fiber-reinforced biopolymers are particularly suitable for producing components with complex geometries in just a few steps and with low material and cost requirements. With their research, the partners are also working on completely new starting conditions for the fabrication of newly developed architectural components: For example, the topology optimization of components according to their structural stress can be easily implemented with additive manufacturing.

Enabling the natural fiber trend in architecture also using additive manufacturing
There is great interest in the use of natural fibers in structural components in architecture and construction because natural fibers have several advantages. They have good mechanical properties combined with low weight and are widely available. As a renewable resource with in some cases very short renewal cycles, they are also clearly a better ecological alternative than synthetic fibers.

In additive manufacturing, large-format elements for the architectural sector have so far mostly been manufactured with polymers based on fossil raw materials. Research in the project 3DNaturDruck should now make the use of natural fibers in architecture possible for additive manufacturing as well.

About 3DNaturDruck
The project 3DNaturDruck is about the design and fabrication of 3D-printed components made of biocomposites using filaments with continuous and short natural fibers.

The project is coordinated by the Department of Biobased Materials and Materials Cycles in Architecture (BioMat) at the Institute of Building Structures and Structural Design (ITKE) at the University of Stuttgart. In addition to the LZH, project partners include the Fraunhofer Institute for Wood Research Wilhelm-Klauditz-Institut (WKI) and the industrial companies Rapid Prototyping Technologie GmbH (Gifhorn), ETS Extrusionstechnik (Mücheln), 3dk.berlin (Berlin) and ATMAT Sp. Z o.o. (Krakow, Poland).

The project is funded by the German Federal Ministry of Food and Agriculture through the Fachagentur Nachwachsende Rohstoffe e.V. under the funding code 2220NR295C.
