Long-lived lamellas for reinforcing buildings

Carbon fiber-reinforced polymer lamellas are an innovative method of reinforcing buildings. There are still many unanswered questions regarding their recycling, however. A research project by Empa's Mechanical Systems Engineering lab is now set to provide answers. Thanks to the support from a foundation, the project could now be launched.

The construction sector is responsible for around 60 percent of Switzerland's annual waste. The industry's efforts to recycle demolition materials are steadily increasing. Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

The construction sector is responsible for around 60 percent of Switzerland's annual waste. The industry's efforts to recycle demolition materials are steadily increasing. Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

Making buildings "live" longer
The reinforcing method developed by Urs Meier, former Empa Director at Dübendorf, has been used in infrastructure construction for 30 years. CFRP lamellas are attached with epoxy adhesive to bridges, parking garages, building walls and ceilings made of concrete or masonry. As a result, the structures can be used for 20 to 30 years longer. The method is increasingly being applied worldwide – mainly because it massively improves the earthquake resistance of masonry buildings.

"By significantly extending the lifespan of buildings and infrastructure, CFRP lamellas make an important contribution to increasing sustainability in the construction sector. However, we need to find a way how we can further use CFRP lamellas after the buildings are being demolished," explains Giovanni Terrasi, Head of the Mechanical Systems Engineering lab at Empa. To achieve this, he wants to develop a method for recycling CFRP lamellas. Convinced by this idea, a foundation supported it with a generous donation. The project officially launched in October.

Gentle separation
First, a mechanical process will be developed to detach the CFRP lamellas from the concrete without damaging them. Initial tests at Empa are encouraging: After the lamellas were separated from the concrete, they still had a strength of 95 percent – even if they had already been used for 30 years.

Then, the demolished CFRP lamellas shall be used to produce reinforcement for prefabricated components. Terrasi's goal: saving thousands of tons of CFRP lamellas from ending up in landfills after the demolition of old concrete structures and reuse them in low-CO2 concrete elements. After completion of the project, Giovanni Terrasi and his team – consisting of Zafeirios Triantafyllidis, Valentin Ott, Mateusz Wyrzykowski and Daniel Völki – want to produce railroad sleepers from recycled concrete, which will be reinforced and prestressed with demolition CFRP lamellas. This would give the "waste-to-be" material a second life in Swiss infrastructure construction.

Vesta Corporation: First Sustainability Report

The Tuscan tannery Vesta Corporation has presented to its stakeholders a report outlining its current commitment and future objectives, with a view to innovating, safeguarding and fostering high-end leather material processing.

Ever since it was founded in 1966 in Ponte a Egola, the Tuscan hub for the production of leather for vegetable tanned soles, Vesta has been a supplier and partner of haute couture and sportswear brands, from lightweight calf and half-calf leather, to heavy leathers made with hind and rump hide, for leatherware and shoes.

The Tuscan tannery Vesta Corporation has presented to its stakeholders a report outlining its current commitment and future objectives, with a view to innovating, safeguarding and fostering high-end leather material processing.

Ever since it was founded in 1966 in Ponte a Egola, the Tuscan hub for the production of leather for vegetable tanned soles, Vesta has been a supplier and partner of haute couture and sportswear brands, from lightweight calf and half-calf leather, to heavy leathers made with hind and rump hide, for leatherware and shoes.

To draft this Report, reference was made to the “Global Reporting Initiative Sustainability Reporting Standards” established by the Global Reporting Initiative (GRI). The information in the balance sheet refers to the year 2022 (from 1 January to 31December 2022). Wherever possible, data for the previous year are included, to allow for a comparison of data over time and to assess the trend of Vesta activities. Sustainability is an objective-driven process. This means that comparing data allows for concretely measuring the company’s progress, as it pursues this accounting process year after year.

The improvement actions already implemented by Vesta involve corporate responsibility from an environmental, social and governance perspective. An example are the improved heating and processing plants (which entails the construction of a new tumbling department based on 4.0 technology). This guarantees significant energy, water and economic savings. Along with numerous corporate certifications, the company has passed the Raw Material Traceability test with a score of EXCELLENT, as well as the Carbon and Water footprint analysis.

As confirmation of its commitment to improving corporate performance levels, Vesta has been upgraded from BRONZE (2020) to GOLD in 2023, as assessed by the Leather Working Group (which measures leather manufacturers’ environmental performance for ecological production and for a systemic management of quality, environmental, safety and ethical factors).

Becoming energy-independent is a major step in the pipeline, involving the installation of a photovoltaic plant. This is complemented by the implementation of a project aimed at totally compensating its CO2 emissions for the year subject to accounting and certification. This neutrality will be achieved through the acquisition of credits deriving from projects certified by the United Nations. For example, with the construction of an important hydro-electric plant to which Vesta is contributing. With regard to production, corporate research is currently focused on developing solutions to reduce water and energy use. It is also implementing circular trends by adopting an increasing number of bio-based products, to guarantee the most sustainable end-of-life and waste management for its products.

Research to reduce shed of microplastics during laundering

A collaboration between Deakin University researchers and Australia’s largest commercial linen supplier Simba Global is tackling a critical global issue, the spread of harmful microplastics through our laundry.

Clothing and textiles are estimated to generate up to 35 per cent of the microplastics found in the world’s oceans, making them one of the biggest contributors. But there is still a lot to be learnt about the characteristics of these microplastics and exactly how and why they are generated.

Researchers at the ARC Research Hub for Future Fibres in Deakin’s Institute for Frontier Materials (IFM) have teamed up with Simba Global, a global textile manufacturing and supply company, to better understand the extent and type of microplastics shed when their products are laundered. Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global is the major linen supplier to Australia’s hospitals, hotels and mining camps, resulting in 950,000 tonnes of textile products – including bedsheets, bath towels, scrubs and much more – going through the commercial laundering process each year. It also supplies international markets in New Zealand, Singapore and the US.

“As part of our research, we will investigate potential solutions including the pre-treatment of textiles to reduce the shedding of microplastics, or even increasing the size of the plastics that break down so they can be better captured and removed by filtration during the laundering process,” Associate Professor Naebe said.

“Microplastics are now ubiquitous in the environment, they’re in the air we breathe, the food we eat and the earth we walk on. The magnitude of the problem is bigger than previously thought.

“Of serious concern is the mounting evidence that microplastics are having a negative impact on human and animal health. There are not just physical, but chemical and biological impacts.”

Associate Professor Naebe’s team have taken the first steps in the project, analysing wastewater samples from commercial laundries with high-powered electron microscopes in their Geelong laboratory, part of the largest fibres and textiles research facility in Australia.

The team recently presented a new scientific paper at the Association of Universities for Textiles (AUTEX) Conference 2023, which started the important process of formally categorising these types of microplastics, as well as developing standard terminology and testing methods.

“Because our understanding of microplastics is still in its infancy, we needed to start right at the beginning,” Associate Professor Naebe said.

“We need to have a standard definition of what is a microplastic. Up to this point that has been lacking, which makes it difficult to compare and incorporate other studies in this area.

“We are now developing a systematic method for sampling and identifying microplastics in laundry wastewater. It has been tricky to measure the different sizes, but this is important information to have. For example, there are studies that suggest some sizes of microplastics are causing more issues in certain animals.

“The next step will be establishing an essential method to prevent the release of microplastics from textile laundering. This may involve a coating on the surface of the textile or better ways to collect the waste during the washing process.”

Simba Global Executive Chair Hiten Somaia said the company had a strong focus on sustainability, driven by the business’ purpose statement.

“We are proud to partner with Deakin University in what is the first significant research into textile microplastic pollution in Australia. What we are most excited about is sharing the results of this research with all other textile markets in Australia – including clothing – and putting an end to microplastic pollution from textiles.”

HeiQ presents a complete set of tailored textile technologies that is said to improve the sleeping environment: "Unlocking Better Sleep". Therefore, HeiQ introduces a range of innovative products designed to enhance the quality of a comfortable night’s rest through sustainable and biobased solutions.

According to a recent study by the School of Architecture, Victoria University of Wellington (New Zealand), “individuals spend more than 50% of their time at home in the bedroom”. Another research from the Fatigue Countermeasures Laboratory, NASA Ames Research Center (United States), concluded that “sleep is critical to health and daytime functioning. For individuals to achieve optimal sleep, they must have access to a sleep environment that allows them to achieve quality sleep.” These are strong indicators that we should treat sleep with the highest importance that it deserves.

The flagship products leading this positive change are the 100% biobased cosmetic technology HeiQ Skin Care, the plant-based deodorizer HeiQ Mint (botanical freshness), the dual action cooling solution HeiQ Cool, and HeiQ Allergen Tech that reduces exposure to inanimate allergens through active probiotics. These biobased innovations are set to redefine the sleep experience and contribute to overall well-being.

HeiQ Skin Care is the most recent addition to HeiQ’s portfolio - a synbiotic textile finish promoting a balanced microbiome for glowing skin. Unlike conventional products, HeiQ Skin Care utilizes pre- and probiotics integrated into a biobased matrix, offering long-lasting cosmetic benefits. It is particularly suited for products that are in direct and long contact with skin, such as pillowcases, duvet covers or bed sheets, acting as a cosmetic care session during sleep.

With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.

New test kit for textile microfibre shedding

In cooperation with testing provider Hohenstein, Under Armour is launching a new fiber-shed test kit. It will help textile companies along the supply chain to develop lower shed materials during product development. The companies carry out the test themselves in-house using the test kit or can commission Hohenstein as a testing service provider.

The kit is a one-off purchase, after which users can buy additional materials from project partner James Heal. By using the new kit, Under Armour can reliably assess the quality and shed rate of the materials from suppliers.

For Hohenstein customers, the test kit is a useful addition to their microplastics tests. It is a quick and relatively inexpensive preliminary test that ensures better early-stage results for the end product.

During the production, wear and laundering of synthetic and natural fabrics, fibre shedding occurs in varying degrees. Hohenstein and Under Armour expect that their test method will help the industry better understand and reduce its contribution to the microfibre problem.

Self-driven and sustainable removal of oil spills in water using textiles

Researchers at the ITA, the University of Bonn and Heimbach GmbH have developed a new method for removing oil spills from water surfaces in an energy-saving, cost-effective way and without the use of toxic substances. The method is made possible by a technical textile that is integrated into a floating container. A single small device can remove up to 4 liters of diesel within an hour. This corresponds to about 100 m2 of oil film on a water surface.
 
Despite the steady expansion of renewable energies, global oil production, oil consumption and the risk of oil pollution have increased steadily over the last two decades. In 2022, global oil production amounted to 4.4 billion tons! Accidents often occur during the extraction, transportation and use of oil, resulting in serious and sometimes irreversible environmental pollution and harm to humans.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

For many technical applications, unexpected solutions come from the field of biology. Millions of years of evolution led to optimized surfaces of living organisms for their interaction with the environment. Solutions - often rather unfamiliar to materials scientists and difficult to accept. The long-time routine examination of around 20,000 different species showed that there is an almost infinite variety of structures and functionalities. Some species in particular stand out for their excellent oil adsorption properties. It was shown that, e.g., leaves of the floating fern Salvinia molesta, adsorb oil, separate it from water surfaces and transport it on their surfaces (Figure 1, see also the video of the phenomon.).

The observations inspired them to transfer the effect to technical textiles for separating oil and water. The result is a superhydrophobic spacer fabric that can be produced industrially and is therefore easily scalable.

The bio-inspired textile can be integrated into a device for oil-water separation. This entire device is called a Bionic Oil Adsorber (BOA). Figure 2: Cross-section of computer-aided (CAD) model of the Bionic Oil Adsorber. The scheme shows an oil film (red) on a water surface (light blue). In the floating cotainer(gray), the textile (orange) is fixed so that it is in contact with the oil film and the end protrudes into the container. The oil is adsorbed and transported by the BOA textile. As shown in the cross-section, it enters the contain-er, where it is released again and accumulates at the bottom of the container. See also the video regarding the oil absorption on the textile, source ITA).
 
Starting from the contamination in the form of an oil film on the water surface, the separation and collection process works according to the following steps:

  • The BOA is introduced into the oil film.
  • The oil is adsorbed by the textile and separated from the water at the same time.
  • The oil is transported through the textile into the collection container.
  • The oil drips from the textile into the collection container.
  • The oil is collected until the container is emptied.

The advantage of this novel oil separation device is that no additional energy has to be applied to operate the BOA. The oil is separated from the surrounding water by the surface properties of the textile and transported through the textile driven solely by capillary forces, even against gravity. When it reaches the end of the textile in the collection container, the oil desorbs without any further external influence due to gravitational forces. With the current scale approximately 4 L of diesel can be separated from water by one device of the Bionic Oil Adsorber per hour.

  • It seems unlikely that a functionalized knitted spacer textile is cheaper than a conventional nonwoven, like it is commonly used for oil sorbents. However, since it is a functional material, the costs must be related to the amount of oil removed. In this respect, if we compare the sales price of the BOA textile with the sales prices of various oil-binding nonwovens, the former is 5 to 13 times cheaper with 10 ct/L oil removed.
    Overall, the BOA device offers a cost-effective and sustainable method of oil-water separation in contrast to conventional cleaning methods due to the following advantages:
  • No additional energy requirements, such as with oil skimmers, are necessary
  • No toxic substances are introduced into the water body, such as with oil dispersants
  • The textiles and equipment can be reused multiple times
  • No waste remains inside the water body
  • Inexpensive in terms of the amount of oil removed.
  • The team of researchers from the ITA, the University of Bonn and Heimbach GmbH was able to prove that the novel biomimetic BOA technology is surprisingly efficient and sustainable for a self-controlled separation and automatic collection of oil films including their complete removal from the water. BOA can be asapted for open water application but also for the use in inland waters. Furthermore, it is promising, that the textile can be used in various related separation processes. The product is currently being further developed so that it can be launched on the market in 2-3 years.

CarboScreen: Sensor monitoring for complex carbon fibre production

Felix Pohlkemper and Tim Röding from Institut für Textiltechnik (ITA) of RWTH Aachen University are developing a technology with their start-up CarboScreen GmbH that makes complex carbon fibre production controllable through sensor monitoring. With the help of CarboScreen technology, it should be possible to double the production speed from the current 15 m/min to 30 m/min in the medium term. The doubling of production speed alone could result in an increase in turnover of up to €37.5 million per year and production plant. Felix Pohlkemper and Tim Röding were awarded third place in the AVK Innovation Award 2023 in the Processes and Procedures category for this ground-breaking development. The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

Felix Pohlkemper and Tim Röding from Institut für Textiltechnik (ITA) of RWTH Aachen University are developing a technology with their start-up CarboScreen GmbH that makes complex carbon fibre production controllable through sensor monitoring. With the help of CarboScreen technology, it should be possible to double the production speed from the current 15 m/min to 30 m/min in the medium term. The doubling of production speed alone could result in an increase in turnover of up to €37.5 million per year and production plant. Felix Pohlkemper and Tim Röding were awarded third place in the AVK Innovation Award 2023 in the Processes and Procedures category for this ground-breaking development. The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

The production of carbon fibres is highly complex. In the current state of the art, however, the manufacturing process is only monitored manually by semi-skilled workers. However, even minimal fibre damage during production leads to a reduction in the quality of the carbon fibre. In extreme cases, it can also lead to plant fires. To ensure production quality, the production speed is currently limited to a maximum of 15 m/min. In fact, the production speed of the systems could be higher. The sensor-based online monitoring of Carbo-Screen makes it possible to increase the production speed to 30 m/min in the medium term. As a result of the increased production volume per system, the specific production costs of the carbon fibre are reduced, which can result in lower prices.

A reduced sales price would make it possible to use carbon fibres and their composite materials even more widely in traditional markets such as aerospace technology and wind energy, as well as for mass production in the automotive industry.

The CarboScreen online monitoring system is currently being developed for industrial use. It is to be validated at an industrial plant in 2024. CarboScreen GmbH was founded as part of EXIST funding and offers AI-supported sensor systems for carbon fibre production. The sensor technology continuously monitors the fibre throughout the entire production process. Deviations are detected automatically.

The winners of the AVK Innovation Award are honoured annually by the AVK Industrievereinigung Verstärkte Kunststoffe. Companies, institutes and their partners are honoured in three categories: products and applications, processes and procedures, and research and science.

Tampon for men aiming to reduce gender dysphoria

Tampon for Men by Finnish hygiene product brand Vuokkoset aims to alleviate the distress transgender men feel related to menstruation. The creative partner behind the idea is TBWA\Helsinki. The product was launched during the international Transgender Awareness Week and sparked a discussion in Scandinavia of the inclusivity of the health and wellness industry.

Research has shown that 93% of transgender men have experienced gender dysphoria related to menstruation. With a tampon designed for men, Vuokkoset sparked a vivid conversation in Finland during the International transgender awareness week (Nov 13 to 19, 2023) with an aim to change perceptions of menstruation and reduce the distress it causes to transgender men.

“Marketing has a huge role in shaping the world around us. As Finland’s leading creative agency and the leading global agency collective, we have an immense responsibility in actively making the world more inclusive. Vuokkoset is a brand that shares this value base and was brave enough to put the campaign together with us in just four short weeks” says Heidi Taina, creative director from TBWA\Helsinki.

Trans men and non-binary individuals may still have menstrual cycles, regardless of hormone therapy choices. This highlights the diversity in experiences related to menstruation among different gender identities.

"When I was young, menstruation felt not only strange but somehow wrong. Our culture does not really acknowledge the diversity of menstruating individuals" says DEI consultant and face of the campaign Dakota Robin, who has been through the gender affirming process himself.

The Tampon for Men will be available as a limited edition in Finland and wider distribution will begin in early 2024. Total sales proceeds are donated to Trasek ry, an organization focused on gender diversity and sexual health. A fully gender-neutral tampon product by Vuokkoset is also being considered.

"Menstrual products - from visuality, advertising to store location - are strongly feminine. It’s time to acknowledge the diversity of menstruating individuals" says Sanna Karhu, CEO of Delipap Oy, the company that manufactures Vuokkoset products.

"This is definitely a step in the right direction. By changing attitudes and broadening perspectives, we can also remove discrimination against gender minorities," concludes Dakota Robin.

It also highlights where new methods, that support the shift away from animal testing, are needed.

To further improve chemical safety in the EU, scientific research needs to deliver data that is relevant to regulating chemicals. In order to enhance the regulatory relevance of scientific data, ECHA has identified the following areas as priorities for research:

  • Hazard identification for critical biological effects that currently lack specific and sensitive test methods: i.e. developmental and adult neurotoxicity, immunotoxicity and endocrine disruption
  • Chemical pollution in the natural environment (bioaccumulation, impact on biodiversity, exposure assessment)
  • Shift away from animal testing (read across under REACH, move away from fish testing, mechanistic support to toxicology studies e.g. carcinogenicity)
  • New information on chemicals (polymers, nanomaterials, analytical methods in support of enforcement)

Background
The European Partnership for the Assessment of Risks from Chemicals (PARC), is a seven-year EU-wide research and innovation programme under Horizon Europe which aims to advance research, share knowledge and improve skills in chemical risk assessment.

ECHA’s role in PARC is to make sure that the funded scientific research addresses current challenges related to chemical risk assessment and adds value to the EU’s regulatory processes.

The key areas of regulatory challenge report can be seen as an evolving research and development agenda aiming to support and inspire the Partnership for the Assessment of Risks from Chemicals (PARC) and the wider research community. The list of research needs is not exhaustive. The next update to the report is expected in spring 2024.

DITF: Pleated textile tube for ventilation of surgical fields

The German Institutes of Textile and Fiber Research Denkendorf (DITF) will be exhibiting at the MEDICA medical technology trade fair in Düsseldorf from November 13 to 16, 2023. At the joint stand of Baden-Württemberg International, a new development will be shown, that can reduce infections during operations.

These nosocomial infections occur when surgical wounds are contaminated by microbes. They can lead to serious complications. The task of the contract development was to create a porous ring tube that reduces the risk of contamination during operations. Germ-free air is introduced into the operating field via the so-called airflow ring, thereby shielding pathogenic germs.

The tube is knitted from polyester and folded. This pleating ensures that the circular shape remains stable, but the tube is still flexible. The outside of the tube is coated so that the air is directed into the inner area of the airflow ring. The ring is attached to the skin with a biocompatible adhesive so that it fits tightly on curved areas of the body such as the face or around joints. The position of the ring can be easily changed.

Archroma celebrates Century of Sulfur Dye Innovation

Archroma celebrated 100 years of sulfur dye innovation at its manufacturing and research hub in Castellbisbal, near Barcelona in Spain.

The milestone was marked at an on-site ceremony attended by more than 250 guests, including authorities from the Catalan government, senior Archroma leaders from Spain and overseas, current and former staff, key customers and suppliers and other important stakeholders.

The Castellbisbal site traces its roots back to 1921, when Joan Cardoner Vidal founded a dye manufacturing company that was eventually bought by Sandoz, which was subsequently acquired by Clariant, and later, SK Capital to create Archroma. Its breakthroughs have helped sulfur dyeing technology become a staple in the production of denim, casual wear and workwear fabrics over the past 100 years, with excellent color fastness and cost-efficiency.

Home to a leading research center that has contributed numerous innovations, Castellbisbal is particularly known for the creation of Archroma’s DIRESUL® RDT range in the 1980’s, which entered the market as the first low sulfide pre-reduced sulfur dyes.

15 member companies of Swiss Textile Machinery Association at upcoming ITMA Asia + CITME

In China, the textile industry is forward-looking and resilient – with a healthy appetite for new technologies and a determination to keep its leading position. Sustainability is increasingly coming into focus, so there is a growing demand for recycling technologies, as well as automated solutions and digitalization. Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association, is clear: “China is the main market for a large number of our association members.” On top of growing consumer demand and technological capabilities, the latest ambitious five-year plan will drive further development of the Chinese textile industry in world markets, and Swiss companies will work with all stakeholders to enable its success.

Market proximity
Swiss companies realized many years ago that geographical proximity is the key to success. Stäubli has started to set up offices in Chinese cities since 1998 and counts 12 locations today, to serve the whole country. In 2002, Itema established a centralized local branch which today has 160 employees in various functions. Loepfe has expanded its presence by creating an independent local business unit to overcome the 9,000 km distance by air, while Uster Technologies has had a Chinese subsidiary since 1982, with offices and service stations in different provinces. Luwa set up its offices and workshop in Shanghai in 1997. Rieter established a presence in mainland China in 2005, driven by a strong commitment to expanding the country’s know-how and expertise – and ten years later opened an advanced research center. All Swiss companies with serious business goals in China have made similar commitments to connect with customers and maintain strong relationships.

Understanding Chinese customers
Swiss companies also understand that Chinese customers require dedicated attention, and that speed is more essential than ever in delivering both machines and services.
Manufacturers in China are seeking cost-effective solutions to remain competitive, while consumers are looking for value in their purchases. Companies need to develop solutions that provide tangible economic benefits to their clients. Furthermore, energy savings have become paramount in China, due to the government's commitment to environmental sustainability and reduced carbon emissions. “Businesses are adopting more energy-efficient processes and technologies to meet stringent energy conservation and emission reduction targets,” says Peter Schnickmann, Managing Director at Luwa Air Engineering (Shanghai). He notes an investment trend for solutions helping Chinese companies cut operational costs and minimize their carbon footprint.

To enhance the reputation of both companies and products – and boost the image of the entire industry – the environmental impact needs to decrease. Priorities are saving water and waste, as well as reducing, replacing or completely eliminating the use of harmful substances. China has a strong demand for environmental-friendly solutions and sustainable technologies.

Customer-oriented in weaving
The huge number of Chinese fabric producers calls for an immense volume of weaving machinery to be supplied by international and local providers. Swiss machinery manufacturers hold an impressive share of this business.
Chinese weavers require advanced technology, with increasingly higher standards of efficiency. In weaving preparation, latest solutions match the speed, quality and reliability now wanted. Weaving machines too offer the eco-efficiency, performance, and ease of use needed, with innovations that extend the scope of sustainable weaving, and open-platform systems configurable to weavers’ specific operations. A huge increase in demand for technical textiles in recent years has been driven by applications such as carbon fiber, aramid and glass fiber.

Profitable in spinning
China’s competitive advantages come from its large-scale and integrated manufacturing capabilities, along with the use of advanced automation and digitization technologies. Spinners aim to capitalize on extended market opportunities, with more economical production. The latest air-jet spinning machines serve these goals, allowing exceptionally low production costs per kilogram of yarn, coupled with high flexibility and reliability. Sustainable yarns are in great demand.

The automation trend in spinning mills focuses on connecting production processes. Data is used to ensure the highest quality standards, most efficient raw material usage, reduction of waste, and energy savings. To make spinning mills more competitive, latest solutions combine cutting-edge hardware, data-enabled software and renowned textile expertise.

DITF: Lignin coating for Geotextiles

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.
