A new chemical process developed by Empa turns cotton into a fire-resistant fabric, that nevertheless retains the skin-friendly properties of cotton.

Conventional flame retardant cotton textiles suffer from release of formaldehyde and are uncomfortable to wear. Empa scientists managed to circumvent this problem by creating a physically and chemically independent network of flame retardants inside the fibers. This approach retains the inherently positive properties of cotton fibers, which account for three-quarters of the world's demand for natural fibers in clothing and home textiles. Cotton is skin-friendly because it can absorb considerable amounts of water and maintain a favorable microclimate on the skin.

For firefighters and other emergency service personnel, protective clothing provides the most important barrier. For such purposes, cotton is mainly used as an inner textile layer that needs additional properties: For example, it must be fireproof or protect against biological contaminants. Nevertheless, it should not be hydrophobic, which would create an uncomfortable microclimate. These additional properties can be built into the cotton fibers by suitable chemical modifications.

Durability vs. toxicity
"Until now, it has always taken a compromise to make cotton fireproof," says Sabyasachi Gaan, a chemist and polymer expert who works at Empa's Advanced Fibers lab. Wash-durable flame retardant cotton in industry is produced by treating the fabric with flame retardants, which chemically links to the cellulose in the cotton. Currently, the textile industry has no other choice than to utilize formaldehyde-based chemicals – and formaldehyde is classified as a carcinogen. This has been an unsolved problem for decades. While formaldehyde-based flame retardant treatments are durable, they have additional drawbacks: The -OH groups of cellulose are chemically blocked, which considerably reduces the capability of cotton to absorb water, which results in an uncomfortable textile.

Gaan knows the chemistry of cotton fibers well and has spent many years at Empa developing flame retardants based on phosphorus chemistry that are already used in many industrial applications. Now he has succeeded in finding an elegant and easy way to anchor phosphorous in form of an independent network inside the cotton.

Independent network between cotton fibers
Gaan and his colleagues Rashid Nazir, Dambarudhar Parida and Joel Borgstädt utilized a tri-functional phosphorous compound (trivinylphosphine oxide), which has the capability of reacting only with specifically added molecules (nitrogen compounds like piperazin) to form its own network inside cotton. This makes the cotton permanently fire-resistant without blocking the favorable -OH groups. In addition, the physical phosphine oxide network also likes water. This flame retardant treatment does not include carcinogenic formaldehyde, which would endanger textile workers during textile manufacturing. The phosphine oxide networks, thus formed, does not wash out: After 50 launderings, 95 percent of the flame retardant network is still present in the fabric.

To render additional protective functionalities to the flame retardant cotton developed at Empa, the researchers also incorporated in situ generated silver nanoparticles inside the fabric. This works nicely in a one-step process together with generating the phosphine oxide networks. Silver nanoparticles provide the fiber with antimicrobial properties and survive 50 laundry cycles, too.

A high-tech solution from the pressure cooker
"We have used a simple approach to fix the phosphine oxide networks inside the cellulose," Gaan says. "For our lab experiments, we first treated the cotton with an aqueous solution of phosphorus and nitrogen compounds and then steamed it in a readily available pressure cooker to facilitate the crosslinking reaction of the phosphorus and the nitrogen molecules." The application process is compatible with equipment used in the textile industry. "Steaming textiles after dyeing, printing and finishing is a normal step in textile industry. So it doesn't require an additional investment to apply our process," states the Empa chemist.

Meanwhile, this newly developed phosphorus chemistry and its application is protected by a patent application. "Two important hurdles remain," Gaan says. "For future commercialization we need to find a suitable chemical manufacturer who can produce and supply trivinylphosphine oxide. In addition, trivinylphosphine oxide has to be REACH-registered in Europe."

A gel that releases drugs
The novel phosphorus chemistry can also be used to develop other materials, e.g. to make hydrogels that can release drugs upon changes in pH. Such gels could find application in treating wounds that heal slowly. In such wounds, the pH of the skin surface increases and the new phosphorus-based gels can be triggered to release medication or a dye that alerts doctors and nurses to the problem. Empa has also patented the production of such hydrogels.

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.

Fraunhofer Institutes pave new ways in plastics recycling

A sustainable society, the renunciation of fossil raw materials, climate-neutral processes - also the chemical industry has committed itself to these goals. For the industry, this means a huge challenge within the next years and decades. This structural change can succeed if all activities - from the raw material base to material flows and process technology to the end of a product's life cycle - are geared towards the goal of sustainable value creation. The key to this is innovation.

Plastics such as polyethylene (PE), polypropylene (PP) or polystyrene (PS), which are currently produced almost entirely from fossil raw materials, are fundamental to many everyday products and modern technologies. The carbon contained in plastics is an important resource for the chemical industry. If it is possible to better identify such carbon-containing components in waste, to recycle them more effectively, and to use them again to produce high-quality raw materials for industry, the carbon can be kept in the cycle. This not only reduces the need for fossil resources, but also pollution with CO₂ emissions and plastic waste. At the same time, the security of supply for industry is improved because an additional source of carbon is tapped.

The "Waste4Future" lighthouse project therefore aims to create new opportunities for recycling plastics in order to make the carbon they contain available as a "green" resource for the chemical industry. "We are thus paving the way for a carbon circular economy in which valuable new base molecules are obtained from plastic waste and emissions are largely avoided: Today's waste becomes tomorrow's resource," says Dr.-Ing. Sylvia Schattauer, deputy director of the Fraunhofer Institute for Microstructure of Materials and Systems IMWS, which is heading the project. "With the know-how of the participating institutes, we want to show how the comprehensive recycling of waste containing plastics without loss of carbon is possible and ultimately economical through interlocking, networked processes." The outcome of the project, which will run until the end of 2023, is expected to be innovative recycling technologies for complex waste that can be used to obtain high-quality recyclates.

Specifically, the development of a holistic, entropy-based assessment model is planned (entropy = measure of the disorder of a system), which will reorganize the recycling chain from process-guided to material-guided. A new type of sorting identifies which materials and in particular which plastic fractions are contained in the waste. Based on this analysis, the total stream is separated and a targeted decision is then made for the resulting sub-streams as to which recycling route is the most technically, ecologically and economically sensible for this specific waste quantity. What cannot be further utilized by means of mechanical recycling is available for chemical recycling, always with the aim of preserving the maximum possible amount of carbon compounds. Burning waste containing plastics at the end of the chain is thus eliminated.

The challenges for research and development are considerable. These include the complex evaluation of both input materials and recyclates according to ecological, economic and technical criteria. Mechanical recycling must be optimized, and processes and technologies must be established for the key points in the material utilization of plastic fractions. In addition, suitable sensor technology must be developed that can reliably identify materials in the sorting system. Machine learning methods will also be used, and the aim is to link them to a digital twin that represents the properties of the processed materials.

Another goal of the project is the automated optimization of the formulation development of recyclates from different material streams. Last but not least, an economic evaluation of the new recycling process chain will be carried out, for example with regard to the effects of rising prices for CO₂ certificates or new regulatory requirements. The project consortium will also conduct comprehensive life cycle analysis (LCA) studies for the individual recycling technologies to identify potential environmental risks and opportunities.

For the development of the corresponding solutions, the participating institutes are in close exchange with companies from the chemical industry and plastics processing, waste management, recycling plant construction and recycling plant operation, in order to consider the needs of industry in a targeted manner and thus increase the chances of rapid application of the results achieved.

The following Institutes are involved in the Fraunhofer lighthouse project "Waste4Future":

• Fraunhofer Institute for Microstructure of Materials and Systems IMWS (lead)
• Fraunhofer Institute for Non-Destructive Testing IZFP
• Fraunhofer Institute for Materials Recycling and Resource Strategy IWKS
• Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB
• Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR
• Fraunhofer Institute for Structural Durability and System Reliability LBF
• Fraunhofer Institute for Process Engineering and Packaging IVV

The Fraunhofer Institute for Biomedical Engineering IBMT, with its long-term expertise in nanotoxicity and nanosafety testing, contributes to a new EC project for water saving solutions for textile industry. This industry uses a vast amount of water for different steps in the textile dyeing process. It also produces a lot of wastewater, which contains a range of chemicals and dyes.

Breakthrough innovations are needed in energy intensive industries to recycle water and create closed loops in industrial processes. 20% of global industrial water pollution comes from textile manufacturing. To reduce the high amount of freshwater used in textile industry, the EC-funded Waste2Fresh project will develop a closed-loop process for textile manufacturing factories in which wastewater is collected, recycled and used again. Novel and innovative catalytic degradation approaches with highly selective separation and extraction techniques will be developed, based on nanotechnology. According to the European Commission, such “closed loops“ would significantly reduce the use of fresh water and improve water availability in the relevant EU water catchment areas, as outlined in the Water Framework Directive.

Closed loop recycling system for wastewater from textile manufacturers
Waste2Fresh meets the above challenges and industry needs by developing and demonstrating (to TRL 7) a closed loop recycling system for wastewater from textile manufacturing factories; to counteract freshwater resource scarcities and water pollution challenges exacerbated by energy intensive industries which are major users of fresh water (for e.g., processing, washing, heating, cooling).

The Waste2Fresh technology is developed to reduce current use of freshwater resources and considerably increases the recovery of water, energy and other resources (organics, salts and heavy metals). The result is a 30% increase in resource and water efficiency compared to the state-of-the-art. The system will ultimately lead to considerable environmental improvements and accordingly reduce the EC and global environmental footprint.

Fraunhofer IBMT expertise in human-toxicity and -safety testing
The Fraunhofer Institute for Biomedical Engineering IBMT will be primarily responsible for performing nanotoxicity and nanosafety testing during the whole technology process (from development to demonstration), ensuring that the developed system and processes meet relevant safety regulations. The Fraunhofer IBMT collaborates with all consortium partners developing and using to develop approaches for ensuring that the developed nanomaterial-based components meet relevant health and safety standards during their use.

For the hazard assessment of the developed nanomaterials, the Fraunhofer IBMT will perform a set of in vitro toxicity studies using commercially available human cell lines. The results of this toxicity studies will be the basis for the development of relevant safety procedures for handling and using the developed recycling technology.

• Spanish entrepreneur Carmen Hijosa is nominated for European Patent Office (EPO) prize European Inventor Award 2021 for her sustainable alternative to leather
• Development of a process for turning pineapple leaves into a soft, durable and versatile natural material
• Environmentally-friendly alternative supports local farming communities and is sought after by major international fashion brands

The European Patent Office (EPO) announces that Spanish entrepreneur Carmen Hijosa has been nominated in the "SMEs" category of the European Inventor Award 2021 for developing a leather alternative made from pineapple leaf fibres. Her innovative textile uses a waste resource and can be produced with less impact on the environment compared with making cow leather. Hijosa has been commercialising her invention through her London-based SME since 2013, and today her natural leather alternative supports farming communities and cooperatives in the Philippines and is sought after by major international fashion brands.
 
The winners of the 2021 edition of the EPO's annual innovation prize will be announced at a ceremony starting at 19:00 CEST on 17 June which has this year been reimagined as a digital event for a global audience.

Inventing a natural textile from waste pineapple leaf fibre  
Conventional leather production is controversial, given the vast resources needed to raise cattle for slaughter, the risk of pollution posed by the chemical-heavy tanning process, and the often dire working conditions in tanneries. Hijosa experienced the reality of global leather production first-hand while working as a World Bank textile design consultant in the Philippines in 1993.

Moved by the negative environmental and social impacts of the local leather production process, she decided to develop a sustainable textile that was suitable for export and made better use of Filipino skills and raw materials. “Pineapple leaf fibres are very strong, fine and flexible, and have been used in the Philippines for 300 years in traditionally hand-woven textiles,” explains Hijosa. “I began to think: ‘What if I make a mesh with these pineapple leaf fibres, which is not unlike leather – a mesh of fibres?’.”
She set out to replicate leather’s mesh of collagen fibres, diving into a 12-year research and development process that involved completing several textile degrees, setting up a company and refinancing her house to keep researching and complete her PhD, before successfully creating the textile called Piñatex and perfecting its production. This involves stripping the cellulose fibres from leaves and first manufacturing textile grade fibres. These are then processed into a non-woven mesh textile, which is further enhanced and softened into a leather alternative.

The raw material that forms the base of Hijosa’s textile is a by-product of pineapple harvesting in the Philippines, offering an additional income to farmers and using an otherwise discarded resource. This waste source is significant with the world’s top ten pineapple producing countries creating enough leaves to potentially replace more than 50% of the world’s leather output with Hijosa’s material. Piñatex also requires much less water than textiles such as cotton, which consumes over 20 000 litres of water per kilogram. What is more, it is produced using fewer chemicals and less CO2 compared with leather production, further enhancing the sustainability credentials of Hijosa’s textile.

Innovation offering consumers more sustainable choices
In 2011, Hijosa filed a patent application for the textile and its production, before founding Ananas Anam as a start-up in 2013 to launch Piñatex commercially. For her, this part of the process was essential: “The IP was a pivotal part for securing funds, securing the product’s future and its market potential.” Today, she remains Chief Creative & Innovation Officer and is at the forefront of new developments in plant-based, waste-based textiles. Her pioneering work has positioned the company as a market leader at a time where consumers are starting to push for more sustainable choices.

Since 2013 the turnover of Hijosa’s company has roughly doubled every year through to 2019 and grown by 40% in 2020. It employs around 10 staff in its London site and works with factories in the Philippines and Spain, as well as the biggest Filipino pineapple-growing collective, which comprises 700 families who benefit from an additional income by supplying waste leaves. Piñatex is currently used by almost 3.000 brands in 80 countries. It can be found in a growing range of products – from trainers to jackets, car interiors, handbags and even in the world’s first all-vegan hotel suite.

A range of other plant-based alternatives to leather exist or are in development – based on anything from apple cores to mushrooms – highlighting the trend towards plant and waste-based textiles. The combined global leather (animal and synthetic) market was valued at EUR 374 billion in 2017, and although real leather is becoming scarce and therefore expensive, the overall market is predicted to grow at a Compound Annual Growth Rate of 5.40% until 2025. Although recent volcanic eruptions near their factories in the Philippines and pandemic-related restrictions have temporarily slowed production, Hijosa says the company’s outlook remains strong as consumers are starting to push for more sustainable choices.

Dr. Carmen Hijosa
… was born in Salas, Asturias, Spain, on 17 March 1952. After moving to Ireland at the age of 19, Hijosa co-founded the luxury leather manufacturing company Chesneau Leather Goods in 1977. There, she also served as director of design and sold to high-end clients such as Harrods. After running the company for 15 years, she began working as a textile consultant for the World Bank, as well as at research institutes in Germany and Ireland on EU-funded projects in the 1990s, bringing her textile design expertise to developing markets. In 1993, the World Bank asked her to consult on the Philippine leather industry. Seeing the industry’s negative environmental and social impact, she was driven to develop a sustainable alternative (a leather replacement derived from pineapple leaves). From 2009 to 2014, Hijosa completed a PhD in textiles at the Royal College of Art in London, further developing her prototype textile. In 2013, she founded the company Ananas Anam Ltd. to commercialise the leather alternative. Carmen Hijosa holds one European patent, EP2576881, granted in 2018.

Water-repellent and more: coating textiles sustainably with chitosan

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners in the HydroFichi project have researched how this can be done: A technology has been developed to provide fibers with the desired properties using biotechnological processes and chitosan.

The manufacture of textiles is, even nowadays, still largely characterized by the use of chemicals: biotechnological processes, enzymes and renewable raw materials have so far played a subordinate role. For example, at present chiefly perfluorinated chemicals are used when finishing textiles to obtain water- and oil-repellent properties. These are harmful to health and also only degradable to a small degree, which is why they remain in the environment for so long.

The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB has been researching sustainable biobased alternatives for some time. In the HydroFichi project – short for Hydrophobic Finishing with Chitosan – which was completed at the end of January 2021, researchers at the institute developed a way of producing chitosan from waste streams and using the biopolymer not only as a sizing agent in the processing of yarns, but also for the functionalization of textiles in the finishing process.

Chitosan from waste for environmental protection, medical purposes or textiles
Chitosan is a renewable raw material that is derived from chitin; after cellulose, it is the second most common naturally occurring biopolymer. Sources of the nitrogen-containing polysaccharide can be crab shells from fishing waste, insect skins and shells that result from the production of animal feed, or – as a vegan variant – the cell walls of mushrooms. The structure of the two molecules is very similar; the only difference is an acetyl group, which is removed when it is converted to chitosan. Chitin is insoluble in water and most organic solvents. Chitosan is also not readily soluble; however, the addition of mild acids makes the biopolymer water-soluble and it can therefore be used as a textile auxiliary.

In order to isolate chitosan from a particular waste stream, chitin must first be obtained from the starting materials by means of demineralization and deproteinization and then its derivative chitosan. The properties of chitosan can be individually adapted by choosing the appropriate conditions. The biomolecule produced in this way can be used directly in a wide variety of practical applications – for example as a flocculant in wastewater treatment or as a drug carrier in medicines.

There are also numerous conceivable uses for chitosan in the textile industry. In sizing, for example, the efficiency of the natural substance has proved convincing in pilot scale tests carried out by the German Institutes of Textile and Fiber Research Denkendorf. Here, the effectiveness was shown in the significantly lower roughness of the yarns after weaving textile fabrics. The values achieved with chitosan from insects were comparable to those from commercial crab shells. In the future, this fact will enable completely new possibilities of extraction in line with the bioeconomy.

As a renewable raw material, chitosan replaces fossil chemicals
“Our aim in the HydroFichi project was to provide the textile industry with a raw material for a wide variety of applications that can be obtained from renewable educts, at the same time avoiding chemicals that damage the environment and health,” explains project manager Dr. Achim Weber, deputy head of the innovation field Functional Surfaces and Materials at Fraunhofer IGB. “In addition to simple coating with chitosan, which protects the fibers, we were also able to use the substance as an anchor molecule to create cross-linking points for a wide variety of functional groups and thus to provide textiles with specific properties such as making them water-repellent. Chitosan can therefore function as a matrix material or template at the same time, and this can be done with a wide variety of fiber materials.”

The finishes were evaluated using standardized tests, but also with specially designed test stands and methods. For example, measurements on treated textiles showed contact angles of over 140°. This means that the fabrics are very water-repellent and confirms that the processing of the textiles has been successful. In a next step, the technology developed at the IGB is to be transferred from the laboratory scale to the much larger pilot scale in order to make the sustainable biomolecule ready for market use as quickly as possible, for example in the sports and outdoor sector.

For the first time biotechnological processes in textile finishing
In the project, the IGB scientists and four partners from the textile industry – the German Institutes of Textile and Fiber Research Denkendorf (DITF), J.G. Knopf's Sohn GmbH, Helmbrechts, and Textilchemie Dr. Petry, Reutlingen – were able for the first time to establish biotechnological processes in raw material extraction and finishing that have proven to be compatible with all textile processes. So far, this is a unique selling point in the finishing of textiles. “We have all recognized the great potential of chitosan for efficient hydrophobization and as a functional carrier. And, thanks to the good cooperation, we were able to successfully establish techniques for tailor-made functionalization of textiles,” adds Dr. Thomas Hahn, who conducts research in the innovation field of Industrial Biotechnology at the IGB. “In addition, other fields of application for the biopolymer are very promising. That is why we initiated the follow-up project ExpandChi immediately after HydroFichi, in which together with our partners techniques are to be developed to use biobased chitosan as a functional carrier to replace other synthetic polymers, for example for a special anti-wrinkle or flame-retardant coating. The textile industry is very interested in utilizing such a sustainable biomolecule as quickly as possible.“

The “HydroFichi” project was funded by the German Federal Ministry of Education and Research (BMBF) under promotional reference 031B0341A; the follow-up project “ExpandChi”, which began in February 2021, is funded under promotional reference 031B1047A.

The Carl Meiser GmbH & Co. KG - started in the early 1950s as a day- and nightwear manufacturer. Over the last 20 years the company has become a specialist in the field of technical textiles. With its brand nopma Technical Textiles the company is present as developer and producer of textile solutions via coatings. The main products are nopma anti-slip - textiles with anti-slip effect, nopma adhesion - adhesive pre-coated films, spacer fabrics and substrates for lamination in automotive interiors, nopma ceramics - abrasive more resistant textile surfaces and nopma silicones - silicone coatings on textile surfaces.

Textination talked to the managing director, Jens Meiser, who joined the company in 2005, realigned the division and developed it into a service provider, about his plans and objectives.

Founded in 1952, Carl Meiser GmbH & Co.KG has changed from a day- and nightwear manufacturer to an innovator in the field of technical textiles, presenting themselves as a specialist for plastic-based coating processes. If you had to introduce yourself in 100 words to someone who does not know the company: What has influenced you most in this development process and what makes you unique?
Innovation is the new normal - This has been true for the textile industry not just since Sars CoV-2. Our industry was one of the first to be disrupted in the early 1990s and has always been subject to constant change. This urge for further development, which is essential for survival, has left its mark on us intensively and has enabled us to manage huge leaps in innovation in recent years

Today we regard ourselves as an innovative development and production service provider with a focus on textile coating. We develop and produce almost exclusively customized special solutions.

Through the combination of coatings on textiles these hybrid materials receive completely new properties.

You manufacture exclusively at your location in Germany. Why? Have you never been tempted to set up subsidiaries in other countries, for example to benefit from lower wage levels?
Today we supply global supply chains from our headquarter in southern Germany. Although we produce in a high-wage country, much more important for us are know-how and the drive of our team to create something new. Globalization will continue to be the key to success in the future. Therefore, subsidiaries in North America and Asia could be very interesting for us in the medium- and long-term perspective. However, this is still too early for us.

You use CIP and Kaizen techniques intensively in your company. How did a Japanese concept come about in the Swabian Alb?
KAIZEN, the change for the better, are actually German virtues. The urge to improve and optimize things is in all of us. Due to the continuous improvement process we do not stand still but evolve constantly. Besides, there is the personal affinity to Japan. A look at another culture simply opens the horizon. And if you additionally recognize parallels in the working methods, it’s even better. 

10 years ago, you turned your attention to new markets: aviation, automotive, protection, caravan and furniture manufacturing, to name just a few. Some of these segments have collapsed significantly during the Covid 19 pandemic. What market development do you expect in the medium term and what consequences will this have for your company?
Of course, the aviation or automotive industry, for example, have substantial problems during or due to the Covid-19 pandemic. Quite honestly, many of these problems existed before. They were further tightened, as if a fire accelerator has been used. Of course, these cut-backs are also hitting us hard economically. But we are pursuing long-term goals. As a medium-sized company, you have to have the resilience to continue on your path. Thanks to our specialisation and the split of our industrial sectors, which we drive forward every day, we manage to decouple ourselves more and more from economic developments in individual industries. For our customers this is a great advantage of relying on a very stable partner with long-term orientation.

We are positive about the future. Megatrends like sustainability, digitization and ongoing globalization will lead to new business models in the above-mentioned sectors, as in many others, and to renewed growth. Our coatings on textiles and flexible woven materials can contribute a wide range of solutions to this. If, for example, materials become lighter with identical usage properties or suddenly become biodegradable, because of biodegradable plastics, many new opportunities will arise.

Tailor-made instead of solutions for major customers: The topic of individualization down to batch size 1 is making up a large part of the discussion today. In 2015, you opened a large development laboratory where you have a wide range of testing technologies for textiles and plastics available. What do you think about individual product solutions, and in which application areas have you successfully implemented them?
In principle, we do not use any standards. We live individualization with the smallest possible batch sizes. In our field, we do not manage batch size 1, but we start with MOQs of 300 running meters at process-safe series production. We have very few finished products, and above all we have no collections. Our development laboratory is the key for this. Together with our customers we have the possibilities to realize very lean development processes.

Even on a laboratory scale, we can develop and test new products within just a few hours. We then strive to scale up to production at a very early stage in order to obtain production series results. This way, we offer our clients speed and power that represent a special potential for our partners.

You register important input factors in the production process and evaluate them in monthly environmental analyses. What are these factors in concrete terms and to what extent have their analyses already changed production operations? How do you define environmental management for your company?
For us, environmental management means a holistic approach. In principle, we operate production units and manufacture products that consume many resources. Due to the high production volumes, this continues to accumulate. Because of this, it is self-understanding that we record and evaluate our input and output flows and derive measures from them. This makes economic sense, but is also necessary because of our responsibility for our environment. Specifically, these are energy consumption values, consumption data of primary chemicals, electricity load peaks, our Co2 footprint, just to name a few. This consideration has changed us in many areas. Today we operate a power plant with gas condensing technology, our free roof areas are greened or carry photovoltaic modules, we offer our employees and visitors electric filling stations and finally we have converted the entire power supply of our factory to environmentally friendly hydroelectric power.

With nopma, you have been building up a brand for the technical textiles industry since several years and communicate this via an Individual website parallel to Carl Meiser GmbH & Co. KG. How did this brand name come about and what is the product portfolio behind it?
This is the name of a first technical textile product from the 1990s. It was a textile - coated with dots. Dots on a knitted fabric. NOPMA. My father created this brand.

In 2016 you invested in an additional production line for nopma products and were able to start a directly serial delivery in the NAFTA area. How do you currently assess the market opportunities for North America and Mexico?
We continue to see opportunities in globalization and thus on the North American market also. However, these markets are still severely affected by the pandemic and there are major distortions. When these return to normal, we surely will see more success on these markets again.

As an innovation leader, Meiser offers solvent-free PU adhesive systems as pre-coatings for lamination. How do you assess the importance of such innovations in the context of REACH?
These innovations offer our customers the opportunity to decouple themselves from the pressure REACH triggers in some industries. However, we also have some products that have been developed newly in recent months. This keeps us busy, but also creates opportunities to open up new market segments.

How have you felt about the corona era to date - as a company and personally? What would you on no account want to go through again and what might you even consider maintaining on a daily basis?
I think this time has also strengthened us as a society, as people and even as entrepreneurs. Each crisis you go through makes you a little more relaxed for the unforeseen, but also more motivated to achieve your goals. In my opinion, there have been a lot of positive things in the last few months. Suddenly, for example, digitalization tools have become accepted in our everyday lives, and I feel that people are paying more attention to others again. Hopefully this will stay this way.

The futuristic "tube" escalator at the Elbphilharmonie Concert Hall is just as impressive as the building itself and the longest escalator in western Europe. In August, a start-up based in Cologne installed an UV technology that keeps the handrails clean at all times. At the same time, you presented an antiviral functional coating that can be applied to all textiles in the form of yard goods. How does this work and for what purposes will this technology be suitable?
We have already been working with antimicrobial finishing techniques for many years. This already started with the swine flu in 2009/2010, when we made initial contacts with a young start-up and launched a development. Due to a lack of market interest, however, this had to be discontinued after a few months. Today we are experts in the field of "antimicrobial equipment by means of coatings". We were also able to build up an enormous amount of knowledge on the subject of approval and biocide regulation. Today, we can support our customers holistically in these areas. The function by skin-compatible active substances from the cosmetics sector with a vesicle booster can kill viruses and bacteria within a few minutes.
Since the pandemic has shown us the enormous importance of a new level of hygiene, the applications are very diverse and differentiated. We have already realized the use in personal protective equipment, work furniture, vehicles and for example gloves. In principle, every application is predestined where textile carriers are exposed to many touches by different persons in high frequency. Here our nopma products offer a new level of protection and hygiene.

To break new ground means decisiveness, overcoming fears - and thus the courage to fail. Not every project can succeed. In retrospect - about which entrepreneurial decision are you particularly glad to have made it?
We fail again and again. This is part of the game. But it has never happened that we did not learn anything. The pandemic situation is another good example. In spring we accepted our corporate responsibility for our society and were one of two companies in Baden-Württemberg to achieve certification for FFP protective masks. Since we did not want to participate in the revolver market at that time, we offered these products only to the public sector at favourable pre-crisis prices. However, the decision makers could not make up their minds for weeks and did not order. This disappointed our whole team very much at that time. Today we have overcome this and have taken a lot of knowledge with us from this development.

NEW HIGH-TECH FIBERS AND YARNS FOR THE SPORTS AND LEISURE MARKET 

With its trade fair premiere at this year's ISPO Munich at the end of January, a newcomer in the sportswear and outdoor market has achieved a well-received appearance: For the first time in Europe, the Japanese company I.S.T Corporation presented its new high-tech fiber and a spinning technology with amazing possibilities at their booth with extensive augmented reality technology. In the sports industry, I.S.T is only known to a few, although there have been first cooperations with well-known manufacturers such as Patagonia in the last seasons.

The CEO and president, Ms. Toshiko “Toko” Sakane, answered Textination's questions. She has been running the company - founded by her father - since November 2016. After completing her bachelor's degree in sociology / human sciences, she worked in the office of the House of Representatives of the Japanese Parliament and the former Japanese Minister of Health and Social Affairs. Later she was managing director of the I.S.T Corporation in Parlin, New Jersey, USA, founded in 2000 - a manufacturer of unique, high-temperature resistant resin materials.

I.S.T is a Japanese company with a comparatively young history. Originally founded in 1983 as an R&D company, you are now also based in the United States and in China. If you had to introduce yourself in 100 words to someone who doesn't know the company: What makes you unique?
I.S.T Corporation is an R&D-oriented Japanese material company with the claim to "invent technologies that no one can imitate". What makes us uniquely competent is our integrated process of material development, innovating our own in-house production methodologies and advancing production technologies. Through this end-to-end cycle, we can achieve various advantages including developing complete original products, securing best quality assurance, and, most importantly, letting us discover new innovations. I.S.T is committed to keep innovating new technologies so they can contribute to enriching people’s lives more.   

Your slogan is: make the impossible possible. In which markets and from which industries do you feel particularly challenged? And with which product innovations for the textile industry do you think you can move the most?
I.S.T’s focus is sporting goods and apparel industry because materials used in this industry demand a wide variety of functionalities and are likely used in extreme conditions. We find it challenging and exciting to offer our advanced innovations. As for the textile industry, we believe our KARL KARL™ spinning technology offers a new great solution for winter active inner wears because it offers all the functions they want, such as warmness, being light-weighted, and easy-care.

A central guideline of the company is the motto "Inventing technologies no-one can copy". Patent protection and a consistent brand policy characterize your activities in the market. But patents can expire and brands can be copied, what makes you uncopiable?
A patent or brand can be copied. However, what makes it impossible to copy us is that our core technologies are embedded throughout our integrated process of material development, in-house production methodologies and advancing production technologies. For example, our KARL KARL™ technology is spinning technology that offers multiple functionalities in one yarn and also can be applied to all different types of and hybrid yarns.
There are some other companies that claim their yarns having a similar function with ours, but those are single function and in a particular type of yarn. This is the most fundamental and significant difference between technologies and competitors. Other companies may be able to copy a single function from us, but it will never be the same as our products that are the results of layers and layers of our integrated innovations.
          
Initially focused on selling technology, you are now a major fiber producer yourself. In addition, you have expanded your portfolio in the past 15 years - for example in the wool market - through acquisitions in Japan and China. Where do you see I.S.T as a player in the textile sector in 2030?
Just as you see a GORE-TEX tag on any outerwear, I would like to see brand names produced by I.S.T on every sports and fashion apparel and people instantly recognize it as the sign of most advanced functional materials.

For the first time you attended ISPO Munich 2020 in January as an exhibitor to present the high-tech fiber IMIDETEX® and new KARL KARL™ yarns to the sporting goods and outdoor industry. What is so special about these two products and what makes them so suitable for use in these markets?  
IMIDETEX®, made of 100% polyimide resin and commonly used in outer space, has possess various advantageous characteristics that other existing super fibers couldn’t overcome, including it being high UV resistant, heat resistant, low water absorption, and has a high tensile strength.
Examples of possible applications for the outdoor market as in composites, would include highly resistive but also durable golf shafts or tennis rackets that can minimize the impact sent to players, and a bicycle that can absorb the shock from the ground throughout a long and competitive race. As for textile, it makes an incredibly durable sail that endures an unforgiving sun. Finally, as yarns IMIDETEX® makes a light-weighted but super strong ropes that people can trust their lives with. IMIDETEX® can provide great performances in extreme natural conditions.
KARL KARL™ is the patented spinning technology that multiplies one core thread with another thread. By expanding the yarn structure itself, it achieves lightness and warmness, which are two seemingly opposite characters to coexist. This technology can be applied to wool, cotton, silk, polyester, nylon … plus there are endless possibilities of developing new yarns by combining different characteristic yarns.
These materials by I.S.T are unrivaled and present infinite possibilities for richer designs in sports fashion scenes.

In a world in which great value is placed on nature and natural materials, man-made fibers are not always welcome. On your website you postulate, I.S.T contributes to the people around the world through chemistry for a better life style. Which aspects make a good case for that?
Our brand-new product, faux-fur, made with KARL KARL™ technology is a good example of our contribution to keep the good balance of natural and synthetic.
The real fur is fashionable but it’s a symbol of animal abuse nowadays. To conserve the nature, our KARL KARL™ faux-fur offers an alternative to fashion, while preventing polluting the ocean from using micro fibers.    

In which socially relevant subject areas do you see a particularly great need for innovation and action during the next 5 years? What is your assessment that your company will be able to offer solutions for this with its products?
We believe that light-weight is a major key factor for better lives and the planet because it allows to save energies and expand the performances.
As the first step, we are bringing in our light-weight technologies, such as IMIDETEX® composites and KARL KARL™ technology, to sporting gears and apparels to support our active lifestyle before extending those technologies to all other markets that can benefit from them.

There are various definitions for sustainability. Customers expect everything under this term - from climate protection to ecology, from local on-site production to the exclusion of child labor etc. What do you do to bring this term to life for your company and what activities or certifications do you rely on?
I.S.T's taking this subject seriously in any aspects. We aggressively approach to research and develop technologies and materials that can support human lives and planet, as well as bringing in sustainable methods and materials to our operations. For instance, we are developing a yarn making from cellulose taken out of used papers without using any harmful chemicals to humans. Also, we invested in a state-of-the-art low emission production facility to make Polyimide materials.
We are RWS (Responsible Wool Standard) certified yarn spinner as far as wool is concerned and we are using RWS certified wool fiber. As for polyester, we are using GRS (Global Recycled Standard) certified recycled polyester and as for cotton, we are using organic cotton fiber. Moreover, our company values producing materials that last forever and not to produce any wastes and/or one-time use materials.
          
Where do you get your inspiration from to research certain technologies or products? Which orders or inquiries from the textile supply chain play a decisive role?
You may think that our life is already filled with things and there isn’t a thing that we cannot get in this world. And yes, we have everything. Yet there are some functions you wish you had in addition to full of those things.
The original idea of developing KARL KARL™ technology was that we wanted to adapt functions like lightness, warmness, quick-drying and easy-care that synthetic fibers have, into natural fibers such as wool and cotton because, obviously natural fibers are much friendlier to human and the earth than petroleum-based fibers.
We believe in and keep our corporate missions: “Develop and manufacture products no others have tried before” and “Handle high-value added products”. Our inspirations for R&D come from our belief, “bringing a wish into a reality”. We do not get an inspiration from others. Our innovations inspire customers and the market.

Breaking new ground means willingness to make decisions, overcoming fears - and thus courage to fail. Not every project can succeed. In retrospect, which entrepreneurial decision are you particularly happy to have made?
Actually, for us, there is no such thing as failed projects because we never give up until each and every project becomes successful.
By carrying on our original corporate missions of “Develop and manufacture products no others have tried before” and “Confront difficulties” that my father, the founder of I.S.T, established almost forty years ago, I.S.T members including myself have learned the joy of overcoming problems and of feeling the victory.
When I took over the business, I have set my goal to “move forward to the global market to inspire the world with our technologies”.
Most recently, by making the decision to enter the sporting gears and apparel market and receiving very positive responses at the ISPO Munich 2020, I’m very pleased that we have made one step forward toward my goal.

TREND REPORT

• Winter sports trends for 2020/2021
• The winter sports industry is increasingly focusing on sustainability
• ISPO Munich (January 26 to 29) to showcase next season’s products

Health will be one of the next decade’s megatrends. The sports industry is, for its part, one of the growth drivers, not least because society now views fitness as a synonym for health. In the future, athleticism will have an ever greater bearing on our everyday lives.

“Medical fitness” refers to ensuring both a sporty lifestyle and the right medical care tailored to the individual needs. Winter sports are also set to assume a challenging yet important role in the future as a vehicle for teaching values within society. Veit Senner, Professor of Sports Equipment and Sports Materials at the Technical University of Munich, says: “Sports must be used as an emotional Trojan Horse for teaching skills and in particular for teaching values.”

There are also other challenges that will need to be faced in the next few years: Children and adolescents need to be encouraged to lead more active lifestyles and our aging population needs to be kept fit and mobile for as long as possible. Senner believes that winter sports could hold the key for today’s youth: “We need to demonstrate the kinds of educational content and values that can be taught through sports.” Attractive products and services therefore need to be created for children. The latest winter sports trends and pro ducts will be showcased at ISPO Munich from January 26 to 29.

Textile manufacturers are giving the winter sports industry an eco-boost
Swedish label Klättermusen impressed the ISPO Award jury so much with its first fully compostable down jacket “Farbaute” that they named it the Gold Winner in the Outdoor category and the winner of the ISPO Sustainability Award.

The first 100% biodegradable down jacket biologically decomposes on the compost heap after around three months (all apart from the zippers and a few snap fasteners which can be removed and reused).

When washed it does not release any microplastics into the environment. Norwegian clothing manufacturer Helly Hansen is launching a new membrane technology for winter 2020/2021 which can be produced without any additional chemicals. The microporous Lifa Infinity membrane is made using a solvent-free process and, together with a water-repellent Lifa outer material, provides extremely impressive protection from the elements. Helly Hansen’s new Lifa Infinity Pro technology also uses the spinning jet dyeing process whereby the color pigments are already injected during the fiber production process. This can save up to 75% water. What’s more, no harmful wastewater is produced.

The winter sports industry is increasingly focusing on sustainability
“The really big trend is for biopolymer fabrics and materials,” says Senner. “The idea is to replace the many different types of plastics that are used in the sports industry with biopolymers.” Together with his team, he is working hard to conduct in-depth research in both areas. This is a trend which French ski brand Rossignol has also identified, whereby it has focused on the use of raw and recycled materials for the production of its new Black Ops Freeride skis. The Black Ops Sender TI model was crowned the winner in its category by the ISPO Award jury.

Alpina Sports is also exploring new ecological avenues and launching a completely sustainable back protector made from 100% sheep’s wool, obtained exclusively from sheep in Switzerland and Norway. The back protector, which consists of three layers of pressed sheep’s wool, meets the standards for protection class 1 and boasts all the impressive properties that the natural material has to offer: In icy temperatures it remains supple, can both warm and cool the wearer, and is odorless. The ISPO Award jury chose Alpina Sports’ “Prolan Vest” as the “Product of the Year”* in the Snowsports Hardware category.

Swedish label Spektrum uses plant-based polymers made from castor oil as well as corn and recycled polyester for its ski and snowboard goggles. The ISPO Award jury was extremely impressed with both the ecological aspects and the execution and named the “Östra Medium” model the Gold Winner.
