Founded in January 1926, Tokyo-based Japanese chemical company Toray Industries, Inc. is known as the world's largest producer of PAN (polyacrylonitrile)-based carbon fibers. But its overall portfolio includes much more. Textination spoke with Koji Sasaki, General Manager of the Textile Division of Toray Industries, Inc. about innovative product solutions, new responsibilities and the special role of chemical companies in today's world.

Toray Industries is a Japanese company that - originating in 1926 as a producer of viscose yarns - is on the home stretch to its 100th birthday. Today, the Toray Group includes 102 Japanese companies and 180 overseas. They operate in 29 countries. What is the current significance of the fibers and textiles business unit for the success of your company?

The fibers’ and textiles’ business is both the starting point and the foundation of Toray's business development today. We started producing viscose yarns in 1926 and conducted our own research and development in nylon fibers as early as 1940. And since new materials usually require new processing methods, Toray also began investing in its own process technology at an early stage. On the one hand, we want to increase our sales, and on the other hand, we want to expand the application possibilities for our materials. For this reason, Toray also began to expand its business from pure fibers to textiles and even clothing. This allows us to better respond to our customers' needs while staying at the forefront of innovation.

Over the decades, Toray has accumulated a great deal of knowledge in polymer chemistry and organic synthesis chemistry - and this know-how is the foundation for almost all of our other business ventures. Today, we produce a wide range of advanced materials and high-value-added products in plastics, chemicals, foils, carbon fiber composites, electronics and information materials, pharmaceuticals, medicine and water treatment. However, fibers and textiles remain our most important business area, accounting for around 40% of the company's sales.

What understanding, what heritage is still important to you today? And how do you live out a corporate philosophy in the textile sector that you formulate as "Contributing to society through the creation of new value with innovative ideas, technologies and products"?

Toray has consistently developed new materials that the world has never seen before. We do this by focusing on our four core technologies: Polymer chemistry, organic synthetic chemistry, biotechnology and nanotechnology. We do this by focusing on our four core technologies: Polymer chemistry, organic synthetic chemistry, biotechnology and nanotechnology. For textiles, this means we use new polymer structures, spinning technologies and processing methods to develop yarns with unprecedented properties. We always focus on the needs and problems of the market and our customers.

This approach enables us to integrate textiles with new functions into our everyday lives that natural fibers and materials cannot accomplish. For example, we offer sportswear and underwear that absorb water excellently and dry very quickly, or rainwear and outdoor clothing with excellent water-repellent properties that feature a less bulky inner lining. Other examples include antibacterial underwear, uniforms, or inner linings that provide a hygienic environment and reduce the growth of odor-causing bacteria. People enjoy the convenience of these innovative textiles every day, and we hope to contribute to their daily comfort and improve their lives in some way.

In 2015, the United Nations adopted 17 sustainable development goals – simply known as the 2030 Agenda, which came into force on January 01, 2016. Countries were given 15 years to achieve them by 2030. In your company, there is a TORAY VISION 2030 and a TORAY SUSTAINABILITY VISION. How do you apply these principles and goals to the textile business? What role does sustainability play for this business area?

Sustainability is one of the most important issues facing the world today - not only in the textile sector, but in all industries. We in the Toray Group are convinced that we can contribute to solving various problems in this regard with our advanced materials. At the same time, the trend towards sustainability offers interesting new business approaches. In our sustainability vision, we have set four goals that the world should achieve by 2050. And we have defined which problems need to be addressed to achieve this.

We must:

1. accelerate measures to combat climate change,
2. implement sustainable, recycling-oriented solutions in the use of resources and in production,
3. provide clean water and air, and
4. contribute to better healthcare and hygiene for people around the world.

We will drive this agenda forward by promoting and expanding the use of materials that respond to environmental issues. In the textile sector, for example, we offer warming and cooling textiles – by eliminating the need for air conditioning or heating in certain situations, they can help reduce energy costs. We also produce environmentally friendly textiles that do not contain certain harmful substances such as fluorine, as well as textiles made from biomass, which use plant-based fibers instead of conventional petrochemical materials. Our product range also includes recycled materials that reduce waste and promote effective use of resources.

The TORAY VISION 2030, on the other hand, is our medium-term strategic plan and looks at the issue of sustainability from a different angle: Toray has defined the path to sustainable and healthy corporate growth in it. In this plan, we are focusing on two major growth areas: Our Green Innovation Business, which aims to solve environmental, resource and energy problems, and the Life Innovation Business, which focuses on improving medical care, public health, personal safety and ultimately a longer expectancy of life.

Innovation by Chemistry is the claim of the Toray Group. In a world where REACH and Fridays for Future severely restrict the scope of the chemical industry, the question arises as to what position chemistry can have in the textile industry. How do chemistry, innovation and sustainability fit together here?

The chemical industry is at a turning point today. The benefits that this industry can bring to civilization are still enormous, but at the same time, disadvantages such as the waste of resources and the negative impact on the environment and ecosystems are becoming increasingly apparent. In the future, the chemical industry will have to work much more towards sustainability - there is no way around it.

As far as textiles are concerned, we believe there are several ways to make synthetic materials more sustainable in the future. One of these, as I said, is materials made from plants instead of petrochemical raw materials. Another is to reduce the amount of raw materials used in production in the first place – this can be achieved, for example, by collecting and recycling waste materials from production or sales. Biodegradable materials that reduce the impact of waste products on the environment are another option worth pursuing, as is the reduction of environmentally harmful substances used in the production process. We are already looking at all of these possibilities in Toray's synthetic textiles business. At the same time, by the way, we make sure to save energy in our own production and minimize the impact on the environment.

Toray's fibers & textiles segment focuses on synthetic fibers such as nylon, polyester and acrylic, as well as other functional fibers. In recent years, there has been a clear trend on the market towards cellulosic fibers, which are also being traded as alternatives to synthetic products. How do you see this development – on the one hand for the Toray company, and on the other hand under the aspect of sustainability, which the cellulosic competitors claim for themselves with the renewable raw material base?

Natural fibers, including cellulose fibers and wool, are environmentally friendly in that they can be easily recycled and are rapidly biodegradable after disposal. However, to truly assess their environmental impact, a number of other factors must also be considered: Primarily, there is the issue of durability: precisely because natural fibers are natural, it is difficult to respond to a rapid increase in demand, and quality is not always stable due to weather and other factors.

Climatic changes such as extreme heat, drought, wind, floods and damages from freezing can affect the quantity and quality of the production of natural fibers, so that the supply is not always secured. In order to increase production, not only does land have to be cleared, but also large amounts of water and pesticides have to be used to cultivate it – all of which is harmful to the environment.

Synthetic fibers, on the other hand, are industrial products manufactured in controlled factory environments. This makes it easier to manage fluctuations in production volume and ensure consistent quality. In addition, certain functional properties such as resilience, water absorption, quick drying and antibacterial properties can be embedded into the material, which can result in textiles lasting longer in use.

So synthetic fibers and natural fibers, including cellulose fibers, have their own advantages and disadvantages – there is no panacea here, at least not at the moment. We believe: It is important to ensure that there are options that match the consumer's awareness and lifestyle. This includes comfort in everyday life and sustainability at the same time.

To what extent has the demand for recycled products increased? Under the brand name &+™, Toray offers a fiber made from recycled PET bottles. Especially with the "raw material base: PET bottles", problems can occur with the whiteness of the fiber. What distinguishes your process from that of other companies and to what extent can you compete with new fibers in terms of quality?

During the production of the "&+" fiber, the collected PET bottles are freed from all foreign substances using special washing and filtering processes. These processes have not only allowed us to solve the problem of fiber whiteness – by using filtered, high-purity recycled polyester chips, we can also produce very fine fibers and fibers with unique cross sections. Our proven process technologies can also be used to incorporate specific textures and functions of Toray into the fiber. In addition, "&+" contains a special substance in the polyester that allows the material to be traced back to the recycled PET bottle fibers used in it.

We believe that this combination of aesthetics, sustainability and functionality makes the recycled polyester fiber "&+" more competitive than those of other companies. And indeed, we have noticed that the number of requests is steadily increasing as companies develop a greater awareness of sustainability as early as the product planning stage.

How is innovation management practiced in Toray's textile division, and which developments that Toray has worked on recently are you particularly proud of?

The textile division consists of three sub-divisions focusing on the development and sale of fashion textiles (WOMEN'S & MEN'S WEAR FABRICS DEPT.), sports and outdoor textiles (SPORTS WEAR & CLOTHING MATERIALS FABRICS DEPT.) and, specifically for Japan, textiles for uniforms used in schools, businesses and the public sector (UNIFORM & ADVANCED TEXTILES DEPT.).

In the past, each division developed its own materials for their respective markets and customers. However, in 2021, we established a collaborative space to increase synergy and share information about textiles developed in different areas with the entire department. In this way, salespeople can also offer their customers materials developed in other departments and get ideas for developing new textiles themselves.

I believe that the new structure will also help us to respond better to changes in the market. We see, for example, that the boundaries between workwear and outdoor are blurring – brands like Engelbert Strauss are a good example of this trend. Another development that we believe will accelerate after the Corona pandemic is the focus on green technologies and materials. This applies to all textile sectors, and we need to work more closely together to be at the forefront of this.

How important are bio-based polyesters in your research projects? How do you assess the future importance of such alternatives?

I believe that these materials will play a major role in the coming years. Polyester is made from purified terephthalic acid (PTA), which again consists of paraxylene (PX) and ethylene glycol (EG). In a first step, we already offer a material called ECODEAR™, which uses sugar cane molasses waste as a raw material for EG production.

About 30% of this at least partially bio polyester fiber is therefore biologically produced, and the material is used on a large scale for sportswear and uniforms. In the next step, we are working on the development of a fully bio-based polyester fiber in which the PTA component is also obtained from biomass raw materials, such as the inedible parts of sugar cane and wood waste.

Already in 2011, we succeeded in producing a prototype of such a polyester fiber made entirely from biomass. However, the expansion of production at the PX manufacturer we are working with has proven to be challenging. Currently, we are only producing small sample quantities, but we hope to start mass production in the 2020s.

Originally starting with yarn, now a leading global producer of synthetic fibers for decades, you also work to the ready-made product. The range extends from protective clothing against dust and infections to smart textiles and functional textiles that record biometric data. What are you planning in these segments?

In the field of protective clothing, our LIVMOA™ brand is our flagship material. It combines high breathability to reduce moisture inside the garment with blocking properties that keep dust and other particles out. The textile is suitable for a wide range of work environments, including those with high dust or grease levels and even cleanrooms. LIVMOA™ 5000, a high quality, also demonstrates antiviral properties and helps to ease the burden on medical personnel. The material forms an effective barrier against bacteria and viruses and is resistant to hygroscopic pressure. Due to its high breathability, it also offers high wearing comfort.

Our smart textile is called hitoe™. This highly conductive fabric embeds a conductive polymer – a polymer compound that allows electricity to pass through - into the nanofiber fabric. hitoe™ is a high-performance material for detecting biosignals, weak electrical signals that we unconsciously emit from our bodies.

In Japan, Toray has developed products for electrocardiographic measurements (ECGs) that meet the safety and effectiveness standards of medical devices. And in 2016, we submitted an application to the Japanese medical administrative authorities to register a hitoe™ device as a general medical device – this registration process is now complete. Overall, we expect the healthcare sector, particularly medical and nursing applications, to grow – not least due to increasing infectious diseases and growing health awareness among the elderly population. We will therefore continue to develop and sell new products for this market.

In 1885, Joseph Wilson Swan introduced the term "artifical silk" for the nitrate cellulose filaments he artificially produced. Later, copper, viscose and acetate filament yarns spun on the basis of cellulose were also referred to as artifical silk. Toray has developed a new innovative spinning technology called NANODESIGN™, which enables nano-level control of the fineness and shape of synthetic fibers. This is expected to create functions, aesthetics and textures that have not existed before. For which applications do you intend to use these products?

In NANODESIGN™ technology, the polymer is split into a number of microscopic streams, which are then recombined in a specific pattern to form a new fiber. By controlling the polymer flow with extreme precision, the fineness and cross-sectional shape of the fiber can be determined much more accurately than was previously possible with conventional microfiber and nanofiber spinning technologies. In addition, this technology enables the combination of three or more polymer types with different properties in one fiber – conventional technologies only manage two polymer types. This technology therefore enables Toray to specify a wide range of textures and functions in the production of synthetic fibers that were not possible with conventional synthetic fibers – and even to outperform the texture and feel of natural fibers. Kinari, our artificial silk developed with NANODESIGN technology, is a prime example here, but the technology holds many more possibilities – especially with regard to our sustainability goals.

What has the past period of the pandemic meant for Toray's textile business so far? To what extent has it been a burden, but in which areas has it also been a driver of innovation? What do you expect of the next 12 months?

The Corona catastrophe had a dramatic impact on the company's results: The Corona catastrophe had a dramatic impact on the company's results: In the financial year 2020, Toray's total sales fell by about 10% to 188.36 billion yen (about 1.44 billion euros) and operating profit by about 28% to 90.3 billion yen (about 690 million euros). The impact on the fiber and textile business was also significant, with sales decreasing by around 13% to 719.2 billion yen (approx. 5.49 billion euros) and operating profit by around 39% to 36.6 billion yen (approx. 280 million euros).

In the financial year 2021, however, the outlook for the fibers and textiles sector is significantly better: So far, the segment has exceeded its goals overall, even if there are fluctuations in the individual areas and applications. In the period from April to June, we even returned to the level of 2019. This is partly due to the recovering sports and outdoor sector. The fashion apparel market, on the other hand, remains challenging due to changing lifestyles that have brought lock-downs and home-office. We believe that a full recovery in business will not occur until the travel and leisure sector returns to pre-Corona levels.

Another side effect of the pandemic that we feel very strongly, is the growing concern about environmental issues and climate change. As a result, the demand for sustainable materials has also increased in the apparel segment. In the future, sustainability will be mandatory for the development and marketing of new textiles in all market segments. Then again, there will always be the question of how sustainable a product really is, and data and traceability will become increasingly important. In the coming years, the textile division will keep a close eye on these developments and develop materials that meet customers' needs.

"Packaging made from bio-based plastics has long been established. We are now supporting the further development of these materials for new areas of application. If in the future the market also offers plant-based materials for technically demanding tasks such as vehicle construction, the bioeconomy will take a decisive step forward," explained Uwe Feiler, Parliamentary State Secretary at the Federal Ministry of Food and Agriculture, in Potsdam. The occasion was the handover of a grant to the Fraunhofer Institute for Applied Polymer Research IAP. The Fraunhofer IAP wants to develop a composite material that consists entirely of bio-based polylactic acid (PLA) and is significantly easier to recycle than conventional fiber composites.

The German Federal Ministry of Food and Agriculture (BMEL) is intensively promoting the development of biomaterials as part of its Renewable Resources funding program. More than 100 projects are currently underway, covering a wide range of topics: from plastics that are degradable in the sea to natural fiber-reinforced lightweight components for the automotive sector. The projects are supported by the Agency for Renewable Resources, the BMEL project management agency responsible for the Renewable Resources funding program.

Easier recycling of fiber-reinforced plastics
PLA is one of the particularly promising bio-based materials. The global market for this polymer is growing by around 10 percent a year. PLA is also used, among other things, as a matrix in fiber-reinforced plastics. In these mechanically resilient plastics, reinforcing fibers are embedded in a plastic matrix.

The Fraunhofer IAP project is now focusing on these reinforcing fibers: "We are further developing our PLA fibers in order to transfer them to industrial scale together with partners from industry. These fibers are ideally suited for reinforcing PLA plastics. The resulting self-reinforcing single-component composite promises great recycling benefits. Since the fiber and the matrix of PLA are chemically identical, complex separation steps are not necessary," explains Dr. André Lehmann, expert for fiber technology at Fraunhofer IAP.

Novel PLA fibers and films are more thermally stable
The challenge with this approach is that conventional PLA has a relatively low temperature resistance. Technical fibers can be produced most economically using the melt spinning process. The Fraunhofer IAP team is now using more thermally stable stereocomplex PLA (sc-PLA) for the fibers. The term stereocomplex refers to a special crystal structure that the PLA molecules can form. Sc-PLA fibers have a melting point that is 40 - 50 °C higher and can therefore withstand the incorporation process in a matrix made of conventional PLA. In the project, the researchers are developing and optimizing a melt spinning process for sc-PLA filament yarns. The partner in this work package is Trevira GmbH, a manufacturer of technical and textile fiber and filament yarn specialties that are in demand from automotive suppliers and contract furnishers, among others. Furthermore, the development of a manufacturing process for sc-PLA reinforced flat films is planned. The international adhesive tape manufacturer tesa SE is participating in this task, and will test the suitability of sc-PLA films as adhesive foils. In a third work package, the Fraunhofer IAP will finally process the filaments in a double pultrusion process to produce granules suitable for injection molding.

Bio-based solutions for the automotive and textile industries
The scientists led by Dr. André Lehmann are certain that the self-reinforced PLA material can conquer many new areas of application. The automotive and textile industries are already showing interest in bio-based materials that are also easier to recycle. In terms of price, PLA would already be competitive here, and now the material is also to be made technically fit for the new tasks.

Professor Alexander Böker, head of Fraunhofer IAP, says: "The steadily growing demand from industry for sustainable solutions underlines how important it is to develop biobased and at the same time high-performance materials. With our research, we are also actively driving the development of a sustainable and functioning circular economy and therefore very much welcome the support from the federal government."

When it comes to the future of motorized mobility, everyone talks about the power drive: How much e-car, how much combustion engine can the environment tolerate and how much do people need? At the same time, new powertrains place ineased demands not only on the engine, but also on its housing and the car body: Carbon fibers are often used for such demanding applications. Like the powertrain of the future, the materials on the vehicle should also be environmentally friendly. That is why recycling of carbon fibers is required. Institutes of the Zuse Community have developed solutions for this.

Carbon fibers consist almost completely of pure carbon. It is extracted from the plastic polyacrylonitrile at 1,300 degrees Celsius, using a lot of energy. The advantages of carbon fibers: They have almost no dead weight, are enormously break-resistant and sturdy. These properties are needed, for example, in the battery box of electric vehicles in structural components of a car body.

The Saxon Textile Research Institute (STFI), for instance, is currently working with industrial partners on combining the static-mechanical strengths of carbon fibers with vibration damping properties to improve the housings of electric motors in cars. The project, which is funded by the German Federal Ministry for Economic Affairs and Energy, is aimed at developing hybrid nonwovens that contain other fibers, in addition to carbon fiber, as a reinforcement. "We want to combine the advantages of different fiber materials and thereby develop a product that is optimally tailored to the requirements", explains Marcel Hofmann, head of department of Textile Lightweight Construction at STFI.

The Chemnitz researchers would therefore complement previous nonwoven solutions. They look back on 15 years of working with recycled carbon fibers. The global annual demand for the high-value fibers has almost quadrupled in the past decade, according to the AVK Industry Association to around 142,000 t most recently. "Increasing demand has brought recycling more and more into focus", says Hofmann. According to him, carbon fiber waste is available for about one-tenth to one-fifth of the price of primary fibers, but they still need to be processed. The key issue for the research success of recycled fibers is competitive applications. STFI has found these not only in cars, but also in the sports and leisure sector as well as in medical technology, for example in components for computer tomography. "While metals or glass fibers cast shadows as potential competing products, carbon does not interfere with the image display and can fully exploit its advantages", explains Hofmann.
 
Using Paper Know-How
If recycled carbon fibers can pass through the product cycle again, this significantly improves their carbon footprint. At the same time it applies: The shorter the carbon fibers, the less attractive they are for further recycling. With this in mind, the Cetex Research Institute and the Papiertechnische Stiftung (PTS), both members of the Zuse Community, developed a new process as part of a research project that gives recycled carbon fibers, which previously seemed unsuitable, a second product life. "While classic textile processes use dry processing for the already very brittle recycled carbon fibers in fiber lengths of at least 80 mm, we dealt with a process from the paper industry that processes the materials wet. At the end of the process, in very simplified terms, we obtained a laminar mat made of recycled carbon fibers and chemical fibers", says Cetex project engineer Johannes Tietze, explaining the process by which even 40 mm short carbon fibers can be recycled into appealing intermediates.

The resulting product created in a hot pressing process serves as the base material for heavy-duty structural components. In addition, the mechanical properties of the semi-finished products were improved by combining them with continuous fiber-reinforced tapes. The researchers expect the recycled product to compete with glass-fiber-reinforced plastics, for example in applications in rail and vehicle construction. The results are now being incorporated into further research and development in
the cooperation network of Ressourcetex, a funded association with 18 partners from industry and science.

Successful Implementation in the Automotive Industry
Industrial solutions for the recycling of carbon fiber production waste are being developed at the Thuringian Institute of Textile and Plastics Research (TITK). Several of these developments were industrially implemented with partners at the company SGL Composites in Wackersdorf, Germany. The processing of the so-called dry waste, mainly from production, is carried out in a separate procedure. "Here, we add the opened fibers to various processes for nonwoven production", says the responsible head of the department at TITK, Dr. Renate Lützkendorf . In addition to developments for applications e.g. in the BMW i3 in the roof or rear seat shell, special nonwovens and processes for the production of Sheet Molding Compounds (SMC) were established at TITK. These are thermoset materials consisting of reaction resins and reinforcing fibers, which are used to press fiber-plastic composites. This was used, for example, in a component for the C-pillar of the BMW 7 Series. "In its projects, TITK is primarily focusing on the development of more efficient processes and combined procedures to give carbon fiber recycling materials better opportunities in lightweight construction applications, also in terms of costs", says Lützkendorf. The focus is currently on the use of CF recycled fibers in thermoplastic processes for sheet and profile extrusion. "The goal is to combine short- and continuous-fiber reinforcement in a single, high-performance process step."

As a result of the new combination possibilities for bio-based hybrid-fiber materials achieved at the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut WKI, the industrial application possibilities for renewable raw materials, for example in the automotive industry or for everyday objects such as helmets or skis, can be expanded.

By increasing the proportion of flax fiber in hybrid-fiber materials to up to 50 percent, the scientists have demonstrated that it is possible to significantly increase the biogenic proportion in composite materials. The special aspect of the tested methods: The fabrics can be individually composed with the help of a weaving machine. In this way, process steps in industrial production, in which materials first have to be merged together, can be omitted. This will achieve reductions in energy and CO2 throughout the entire production process.

Successfully woven: Different hybrid fabrics
In view of the increased demands being placed upon environmental and climate protection, science and industry are seeking sustainable alternatives to conventional materials in all branches of production. As a material, natural fibers offer a sustainable solution. Due to their low density and simultaneous high stability, natural fibers can be used to produce highly resilient light-weight-construction materials which are easy to recycle. In the “ProBio” project, scientists from the Fraunhofer WKI have therefore addressed the question as to how the proportion of natural fibers in bio-based hybrid-fiber materials can be increased as significantly as possible. A double-rapier weaving machine with Jacquard attachment was thereby utilized in order to produce the bio-based hybrid-fiber materials.

The researchers thereby focused specifically on bio-based hybrid-fiber composites (Bio-HFC). Bio-HFC consist of a combination of cellulose-based fibers, such as flax fibers, and synthetic high-performance fibers, such as carbon or glass fibers, for reinforcement. Bio-HFC can be utilized in, for example, vehicle construction. As an innovation in the “ProBio” project, the researchers interwove differing fiber-material combinations, reinforcing fibers and matrix fibers with the aid of the double-rapier weaving machine. This procedure differs from the process in which finished fabrics are layered on top of one another.

“We have combined the advantageous properties of the fiber materials within a composite material in such a way that we have been able to compensate for weak points in individual components, thereby achieving new properties in some cases. In addition, we have succeeded in increasing the proportion of bio-based fibers to up to 50 percent flax fibers, which we have combined with 50 percent reinforcing fibers,” says project team member Jana Winkelmann, describing the procedure. The bio-hybrid textiles, each consisting of 50 percent by weight carbon and flax fabric, are introduced into a bio-based plastic matrix. The composite material possesses a flexural strength which is more than twice as high as that of the corresponding composite material made from flax-reinforced epoxy resin. This mechanical performance capability can significantly expand the application range of renewable raw materials for technical applications.

With the weaving machine, the scientists have successfully combined innovative light-weight-construction composite materials with complex application-specific fabric structures and integrated functions. Reinforcing fibers, such as carbon and natural fibers, as well as multilayer fabrics and three-dimensional structures, can be woven together in a single work step. This offers advantages for industrial production, as production steps in which materials first have to be merged together can be omitted. “We have succeeded, for example, in utilizing conductive yarns or wires as sensors or conductor paths directly in the weaving process, thereby producing fabrics with integrated functions. The introduction of synthetic fibers as weft threads enables the production of bio-hybrid composites with isotropic mechanical properties,” explains Ms. Winkelmann.

Weaving technology makes it possible to create new products with a high proportion of bio-based components on a pilot scale. The project results provide an insight into the diverse combination possibilities of natural and reinforcing fibers and demonstrate opportunities for utilization not only in vehicle construction but also for everyday objects such as helmets or skis. The results will be presented within the framework of the 4th International Conference on Natural Fibers, ICNF, July 2019 in Porto, Portugal. The “ProBio” project, which ran from 1st July 2014 to 30th June 2019, was funded by the Lower Saxony Ministry of Science and Culture (MWK).

Background
Sustainability through the utilization of renewable raw materials has formed the focus at the Fraunhofer WKI for more than 70 years. The institute, with locations in Braunschweig, Hanover and Wolfsburg, specializes in process engineering, natural-fiber composites, wood and emission protection, quality assurance of wood products, material and product testing, recycling procedures and the utilization of organic building materials and wood in construction. Virtually all the procedures and materials resulting from the research activities are applied industrially.

Whether biodegradable geotextiles, wearables from thermoplastic elastomers or functional textiles from 3D printers - the scope of plastics developed at the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT is wide.

Insights into these projects were provided from October 16th - 23rd  in Düsseldorf: At the K, scientists presented their work on thermally and electrically conductive, biodegradable, bio-based compounds as well as compounds suitable for additive production.
 
Textile composites from the 3D printer
In the "AddiTex" project, plastics were developed that are applied to textiles in layers using 3D printing and give them functional properties. A special challenge in the development was the permanent adhesion: The printed plastic had to be both a strong bond with the textile and sufficiently flexible to be able to participate in movements and twists.

A flexible and flame-retardant compound was developed, which is particularly suitable for use in the field of textile sun and sound insulation, as well as a rigid compound, which is used, among other things, for reinforcing the shape of protective and functional clothing.

Geotextile filter for technical-biological bank protection
Geotextile filters for technical-biological bank protection are the focus of the "Bioshoreline" project. It stands for gradually biodegradable nonwovens, which allow a near-natural bank design of inland waterways with plants. They consist of renewable raw materials and are intended to stabilize the soil in the shore area until the plant roots have grown sufficiently and take over both filter and retention functions. The ageing and biodegradation of the fleeces begin immediately after installation, until the fleeces are gradually completely degraded.

Prototypes of the geotextile filters are currently being tested. Female scientists evaluate the plant mass formed above and below ground with and without geotextile filters as well as the influence of the soil type on plant growth and the biological degradation of the filter.

Wearables made of thermoplastic elastomers
In addition, Fraunhofer UMSICHT is developing novel, electrically conductive and flexible compounds that can be processed into thermoplastic-based bipolar plates. These plastics are highly electrically conductive, flexible, mechanically stable, gas-tight and chemically resistant and - depending on the degree of filling of electrically conductive additives - can be used in many different ways. For example, in electrochemical storage tanks (batteries), in energy converters (fuel cells), in chemical-resistant heat exchangers or as resistance heating elements.

Another possible field of application for these plastics: Wearables. These portable materials can be produced easily and cheaply with the new compounds. It is conceivable, for example, to form garments such as a vest by means of resistance heating elements. The idea behind this is called Power-to-Heat and enables the direct conversion of energy into heat.

Over the past ten years or so, our family-owned company based in rural Baden-Wurttemberg has changed from a classic textile printing company into a system supplier. A central precondition for this is our knowledge of our own strengths. We rely on proven printing solutions. We do not rush into exchanging them with the latest trend. Instead, we examine whether another, innovative application can be found for them. Or whether one it is possible to combine the tried and tested with a new approach. For example, we were able to solve electronic requirements by printing technology. This area is our second focus. I am a Master of electronic engineering and completed my apprenticeship at Bizerba, a worldwide leading specialist in industrial weighing and labeling technologies. My wife brought me to the textile industry.

In which product area do market and customers challenge you in particular? And on which socially relevant areas do you see a particularly great need for innovation in the upcoming 10 years? What is your assessment that textile finishing will be able to offer solutions?
Mobility is an issue that will be of great concern to all of us in the coming years. In this area trump is what brings little weight, can be produced in a resource-saving way and is easy to shape. All these requirements are met by textile carrier materials and composites. However, textiles as a pure material are still not well-known in public and in our target industries. This understanding should be promoted.

Were fashion and clothing yesterday and do hybrid product developments like your ceramic-coated high-tech fabrics represent the future? When would the company name have to be adjusted, and how long will you keep your broad range of products and services?
In any case, it is true that the textile market, especially the clothing sector, is becoming smaller and smaller in Germany, while the market for technical textile solutions is growing. Of course, this also has an impact on our business and our priorities. Textiles are now found in so many products - we would never have dreamed about before!

As far as the company name is concerned, we have discussed it extensively. We decided to keep it because it is still right. The textiles we talk about are mostly a functional material, but they still remain textiles. And the technology with which we manufacture our high-tech coatings continues to be the printing technology ...

"Without innovation no future" - In five years time, you celebrate the company’s 50th anniversary, with which fundamental corporate decisions will you then have secured the future of your customers and employees?
You already mentioned the landmark decision: "Innovation, innovation, innovation." We can secure our future through innovation only. This means that we must constantly question ourselves and be prepared to be widely interested in attending trade fairs and exhibitions and find out what people are looking for.

Innovation manager or tinkering: What does it mean for a medium-sized family business high up on the Swabian Alb having to profile on specialties in the niche? What advantages do you see compared to large companies?
The Swabian Alb is a traditional textile region. In 1980, about 30,000 people worked here in the textile industry. In 2005 it was barely a sixth. There is not much else left to do than to look for profitable niches and to show a clear profile. Perhaps the special thing about it is that we are not alone in this. Basically, all successful textile companies in our region have undergone a similar process.

As a small - and owner-managed - company, we have the shortest and fastest decision-making channels. That makes us more flexible than a big company. A budget is not questioned five times, but it is decided. If we make a trial, we can evaluate it in the evening and react the very next day. If something doesn't work, we don't need a meeting – then that's it.

At the same time, we do not automatically have a budget for research and development. We first have to carve this out elsewhere. And we do so in the knowledge that it can also be for the trash can. Within the framework of this budget, entrepreneurs have the greatest possible freedom.

To break new ground means decisiveness, overcoming fears - and thus the courage to fail. Not every project can succeed. Which entrepreneurial decision are you particularly glad to have made in retrospect? What makes you proud?
That's easy (Michael Steidle laughs)! We have realized a company’s request that has driven us for months, which in the end has also awakened personal ambition. That was the introduction to these technical coatings, the key and door opener for technical textiles in general. In doing so, I revived old resources, almost by chance. Meaning: my knowledge in electronics. That's when I realized that with a textile you can do completely different things. When you see the finished product on sale after two or three years, it makes the whole team proud!

Every man for himself, God for us all: With which sectors in the textile industry and from neighboring sectors do you want to get closer cooperation beyond competitive borders? For which higher-level problems do you consider this to be indispensable?
Actually, it is not so much a matter of competitive boundaries - cooperation with innovative competitors would always be good for the end product, but that is the case in every industry!

For us, cooperation with other companies in the textile chain is important, i.e. the upstream company. Let’s assume that I am looking for a special fabric for my coating, which in turn has to be made from a special yarn. Then I am already dependent on two companies. Fortunately, we have innovative companies right on our doorstep. But sometimes we have to go further to find the right partner. Characteristics such as willingness to take risks, a common entrepreneurial interest and a passion for the final product are enormously important in a successful cooperation.

Together with your customers, universities, specialist institutes and research institutes, porject-related you work on market-ready solutions. Do you think Germany is a good breeding ground for innovative entrepreneurs? What should happen to stay successful in international competition?
The cooperation with the institutes makes perfect sense; after all, it is their task to carry out research for companies that cannot shoulder such assignments on their own. This includes testing facilities as well as applying for funding, which is only possible in cooperation with research institutes. However, they are public institutions and therefore per se have a different objective than a company: We need to bring a promising idea to market as soon as possible so that it generates a return. A research institute does not have this pressure.

And Germany as a location? Germany is a brilliant location! But we have an infrastructure bottleneck: I mean roads and internet connections as well as access to funding or venture capital. That does not exist in Germany in the true sense anyway. Finding investors for an idea is therefore extremely difficult.

Let me give you an example: Over the years, I have received around 14,000 euros in subsidies for a coating innovation. An American entrepreneur had a very similar idea. He was able to raise about $ 35 million within three years through venture capital, crowd funding, and grants. In the end, he did not even know what he should spend the whole money on!

In addition, for us as a company in Germany, the large, open economic area of Europe is important!

You are the first textile printing company to be certified for screen printing as well as for rotary and rouleaux printing according to the GOTS standard. How important do you consider such certification as a unique selling point in the competition?
Such certifications are important because we work with clients in the upper and premium segments. Especially in times in which - undoubtedly justified - ever greater demands are placed on sustainable business and also the external presentation receives a steadily growing attention, we can support our clients this way. We therefore offer different printing methods, all of which are certified. One thing we have to be aware of is, that if we - and all the other members of the textile chain – charge the additional costs, the price mark-up would be so enormous that nobody would accept it anymore.

How do you feel about the willingness to perform of the succeeding generation? And who would you recommend to join the textile industry and to whom would you dissuade from it?
We work a lot with students and interns. Every year we give two students the opportunity to work and research in our company for their master's thesis. With these young talents, we often experience great commitment and the ambition to bring their own project to a meaningful completion. At the same time, it is difficult for us to fill our apprenticeships; the idea of working eight hours daily, five days a week seems daunting.

And who would I recommend to join the textile industry? For decades, we vehemently discouraged our offspring from working in the textile industry, because one said it has no future ... As a true high-tech industry, it is interesting for engineers, process engineers, chemists or electronic engenieers. Very important: for people with visions! If you are looking for the classic textile industry you have to be prepared to work worldwide and you will not be unemployed. Many companies are desperately looking for plant managers or managing directors for their non-European branches.

 

• Premiere: “Process live” format
• Lightweight Technologies Forum to present hybrid lightweight construction
• Trade fair kick-off event: International Composites Congress (ICC)

In the competition of lightweight construction and design materials, composites are among the winners – automotive engineering, aerospace, wind energy, boatbuilding and construction can no longer do without glass- and carbon-fibre reinforced plastics (GFRP & CFRP). Nevertheless, the greatest impetus right now is coming from the composites industry itself: technological advancements in the process chain. From 6 to 8 November, COMPOSITES EUROPE in Stuttgart will drive home that point.

Trade fair visitors will meet more than 350 exhibitors from 30 countries who in Stuttgart will present state-of-the-art technology and the potential of fibre-reinforced composites – in the exhibition area as well as in numerous event areas, lecture forums and themed tours.

With the new “Process live” format, coordinated processing and manufacturing processes will become the visible focus of this year’s COMPOSITES EUROPE. Mechanical and plant engineering companies will get together in group exhibits to showcase their technologies in live interactions – thus enabling visitors to experience sub-processes presented in a larger context.

Partnerships in the process chain accelerate growth in the industry
Among others, the cutting specialists Gunnar (Switzerland), the composites automation experts Airborne (Netherlands) and the gripping systems providers Schmalz (Germany) will join forces to create a combined production cell in a process-safe depiction of the entire value chain from roller materials to the finished layer structure of a composite component. In this setup, interlocking hardware components are fully connected with each other via software. “Cooperation among processors is getting closer and closer. These partnerships within the process chain are accelerating the growth of the composites industry; that’s what we want to show with the new ‘Process live’ format”, says Olaf Freier, event director of COMPOSITES EUROPE.

Lightweight Technologies Forum: Platform for multi-material lightweight construction
Besides the optimisation of the process chain, industry research today is heavily focused on the use of GFRP and CFRP in multi-material systems. The Lightweight Technologies Forum will once again demonstrate how composites play to their strengths alongside other materials in the material mix for hybrid structural components. A total of 16 exhibitors will present materials, tools and exhibits here – from fillers to bonding agents and presses for laminating different materials to semi-finished hybrid products.

In various presentations, experts will provide an overview of new products in manufacturing and joining technology as well as applications and lightweight engineering references from the automotive, aerospace and construction sectors. Support for the Lightweight Technologies Forum is provided by the German Federal Ministry for Economic Affairs and Energy.

From digitalisation to recycling: Know-how in the supporting programme
A presentation programme, themed tours and special areas complete the COMPOSITES EUROPE lineup. Manufacturing technology, recycling, digitalisation and thermoplastics will be central themes in the programme of the COMPOSITES Forum, which will also feature exhibitors presenting application examples from automotive engineering, aerospace, construction, mechanical engineering, wind energy and shipbuilding.

Themed guided tours, meanwhile, will lead visitors straight to the stands of selected exhibitors ready to explain the latest innovations in fibreglass, thermoplastics, automotive engineering, wind energy and construction.

Special areas and group stands to highlight new ideas
Hosting the special area “Industry meets Science”, the Institute of Plastics Processing (IKV), the leading European research institute for plastics technology based in Aachen, will showcase developments in process technology, design, quality assurance and repair.

The exhibitors at the “Bio-Based Composites Pavilion”, which will again be set up in cooperation with the nova-Institute, will reflect the development of the market for green composites. The focus will be on application options of wood-polymer composites (WPC), natural fibre composites (NFC), bio-based thermoplastics and thermosets for composites, and bio-based plastics.

Moreover, numerous young companies will thrill visitors with fresh ideas: the industry newcomers will present themselves at a group stand funded by the Federal Ministry for Economic Affairs and Energy (BMWi). They will cover a wide range of topics from semi-finished carbon-fibre products to metal foams to production lines for multi-material 3D fibre laminates.

Even the automotive experts of tomorrow will have their own forum at the trade fair: under the banner of “Formula Student”, students and apprentices will show visitors racecars they themselves have designed.

Kick-off event: 4^th International Composites Congress (ICC)
The International Composites Congress (ICC) will once again kick off COMPOSITES EUROPE. In a series of presentations starting the day before the trade fair (5 and 6 November), international experts at the event with the headline topic “Composites – On the Path to Becoming a Key Industry?” will speak about and discuss applications, materials, process technologies and market prospects.

Offshore expansion and onshore repowering ensure growth

• Wind theme day with guided tour November 29th
• Lectures about material trends

With an investment volume of EUR 14 billion in the offshore sector alone, the European wind power industry has set a new record high in the first half of 2016. This figure and the view on the still open approval procedures in this segment as well as the onshore upcoming generational change from existing to modern facilities (repowering) show that the potential for growth is far from being exploited. Also in America as well as in Asia and the Pacific area a new emerging wind energy sector is also driving demand for fiber composites. The COMPOSITES EUROPE exhibition will be showing in Dusseldorf from November 29th to December 1st 2016 the latest trends and developments.

Theme Day: Wind meets Composites

Sector specialists such as Gaugler & Lutz, DD Compound, 3D Core, LAP and Power & Composite Technology will be showing current technologies at the COMPOSITES EUROPE, latest machine tools and manufacturing processes for the wind power industry. A highlight for all wind experts: On November 29th will be the theme day „Wind meets Composites" at the fair. This day will be sponsored by GUNNAR International, Weissenberger, Hexion and SAERTEX. Engineers of aerodynamics, materials science, lightweight construction and production technology will be able to exchange ideas with purchasers, exhibitors and wind energy specialists in the composite sector. The focus will be, among other things, on topics such as the influence of material selection, on design, weight, stability, processing or production processes as well as on certification, standardization and automation in rotor blade construction.
 
Guided theme walks

An optimal overview of exhibitors' offer on the topic wind is given to visitors by the opportunity of taking part at guided tours. Here they will specifically directed to various exhibitors from the wind segment, where they can get within 10 minutes information about their products and innovations.

JEC World, the largest international composites show, opened at the new Paris Nord Villepinte venue for the first time. Its content, design and scenery were the object of much admiration. New records have been reached this year, with a total surface of 62,000 sqm, 1,300 exhibitors and 36,946 professional visits in attendance. One of the show’s new features consisted of the “Planets”, four new display areas totalling  more than 1,800 sqm.

A World of Difference
JEC Group presents composites in a completely different style
According to JEC Group President and CEO Mrs Frédérique Mutel, the unanimous reaction to the show was pride in the composites industry and delight at JEC Group’s showcasing of it. “The JEC teams have indeed done a wonderful job at presenting composites to the world in the most impressive way,” she said. “An enormous range of products and technologies were presented, shared and showcased at JEC World 2016. Composite materials continue to become more widespread. In a world where energy savings and recyclability are sought, composites seem to stand out as one of the best answers. Innovative solutions must be found for current and upcoming challenges in terms of higher performance, lower weight, reduced costs and processing time, and of course, addressing the pressing matters of environmental concerns.”

This year’s event also featured the launch of four Innovation Planets, each one addressing a specific end-user market (the Aero Planet, the Auto Planet sponsored by Hexion, the Sports Planet and the Sustainable Planet). These areas were very popular ones, where attendees could see, touch and experience Innovative composite parts, observe demos, and ask questions about the innovations.

New name, new venue for the comfort of all attendees
To truly reflect the global dimension of the exhibition, which included participants from more than 100 countries, the event has taken on a more suitable name, “JEC World”. For the convenience of exhibitors and visitors, it has also moved northward from the southern part of Paris, in order to be closer to Paris Charles de Gaulle Airport, train stations and many other connecting opportunities. The total surface has
increased to 62,000 sqm, offering visitors and exhibitors a bigger show with enhanced features to improve the visiting experience. These include a new mobile application, Internet connections on the entire floor, a concierge service open to all, and digital touch screens.

High-level content delivered by JEC Expertise
Over the three days, participants were able to gather a wealth of information from the 11 top-notch conferences, some of them organized in partnership with Inovev, Cetim, e-Xstream, Stanford University, Onera, Composites Innovation Cluster, AZL and Dassault Systemes. The 30 technical sales presentations and the 40+ presentations on the “Planets” also covered a vast range of current and future composite topics.

A large delegation of Korean visitors and exhibitors showed up to proudly represent the Republic of Korea, the event’s Country of Honour. They showcased their latest advances, particularly in carbon, proving to the world that they have become a key player in the composite industry.

Other noteworthy events included the JEC Innovation Awards with its 29 prizewinners; the Automotive Composites Circle; the Live-Demo zones; the Composites in Action areas; and the 1,950 B2B Meetings that were organized.

The popularity of the event keeps on growing, which is very encouraging for next year’s session. Many exhibitors have already confirmed their participation.
