From the Sector

The substance graphene can become increasingly important as a component in textile catalysts when purifying water from textile dyeing as has been shown in a recently completed doctoral project at the University of Borås.

In his project, Milad Asadi, a new doctor in Textile Technology, has modified conventional yarn by encapsulating iron particles in graphene and developed a multifunctional smart e-textile. The focus was on developing a method for purifying wastewater from textile dyeing. The smart e-textile acts as a catalyst that causes the substance hydrogen peroxide to be formed, which is needed in order to break down pollutants in wastewater.

The project has generated a complete textile reactor for the treatment of wastewater through the so-called electro-Fenton technology, which is mainly used industrially to purify wastewater. The novelty of the technology is to use the properties of both graphene and iron, which is the main catalyst.

“Previous research has mainly been about the treatment of wastewater by using chemicals to break down the textile dyes. My project is the first where graphene, which is electrically conductive, is used to encapsulate iron. The e-textile can also be used several times, unlike when chemicals are used and which are then rinsed off. The challenge in the project was to scale up the technology so that the treated yarn can be fed into automatic knitting machines”, explained Milad Asadi.

The e-textile catalyst can be reused and hydrogen peroxide is formed internally inside the reactor, which reduces the use of biological catalysts, making the technology more sustainable compared to chemical methods.

Genomatica (Geno) alongside longtime collaborator Aquafil [ECNL:IM] successfully completed the first demonstration scale production runs for plant-based nylon-6. The material is intended to reshape the $22B nylon industry, enabling brands to meet demand from consumers for sustainable everyday materials from apparel to automotive parts to carpets. Geno and Aquafil have produced the first several tons of plant-based nylon-6 building block caprolactam, have converted it to nylon-6 polymer, and are now in the process of transforming it for evaluation in nylon applications such as yarns for textile and carpet and engineering plastics as part of pre-commercial quantities from demonstration production taking place in Europe.

The companies have been collaborating to first produce pilot-scale quantities of plant-based nylon-6 and have now advanced to produce pre-commercial quantities at demonstration scale which will help determine the final design of future commercial plants. The material will go to leading global brands and their value chain partners who are eager to explore and develop renewable products, create showcase goods and test feedback with customers.

Plant-based nylon-6 is Geno’s third major product line on a path to commercialization. The company has executed high impact deals with a range of brands to accelerate the global commercialization of sustainable materials, with the potential to reduce greenhouse gas emissions by 100 million tons in upcoming years. Recent milestones advancing the sustainable materials transition include: a collaboration with lululemon (NASDAQ: LULU) to bring plant-based materials into lululemon’s products, a production milestone with partner Covestro (OTCMKTS: COVTY) for plant-based HMD used in sustainable coatings, and a partnership with Asahi Kasei (OTCMKTS: AHKSY) and a newly formed venture with Unilever (NASDAQ: UL) to commercialize and scale plant-based alternatives to feedstocks like palm oil or fossil fuels, to make key ingredients used in everyday cleaning and personal care products.

• Commitment for a sustainable fashion industry

RadiciGroup participated in the third edition of PHYGITAL SUSTAINABILITY EXPO, which took place on 11 and 12 July in Rome. The event was focused on the ecological transition of fashion and design brands through technological innovation.

During the “narrated fashion show”, at the archaeological site of the Museo Dei Fori Imperiali, two sustainable garments by RadiciGroup were shown: the first completely recyclable ski suit made with recycled nylon and the Yamamay swimsuit made with polyester yarn obtained from recycling of plastic bottles.

Yamamay chose the sustainable polyester yarn Repetable® by RadiciGroup, for its new green beachwear proposal, with the aim of combining beauty and sustainability. Repetable is an innovative polyester yarn obtained through a process of recycling plastic bottles. Compared to virgin polyester, Repetable allows lower CO₂ emissions (-45%), lower water consumption (-90%) and lower energy consumption (-60%), while guaranteeing high performance. The new line “Edit” by Yamamay, which includes the swimsuit made with Repetable, has already been on the market since the end of last May.

The participation of RadiciGroup in the PHYGITAL SUSTAINABILITY EXPO represents further confirmation of the Group commitment to creating a fashion industry that is increasingly respectful of the environment, thanks to the involvement of all the players in the supply chain, which are most sensitive to sustainability.

On the occasion of the Techtextil fair in Frankfurt, the Chairman of VDMA’s Walter Reiners-Stiftung Foundation, Peter D. Dornier, has awarded prizes to seven successful young engineers.

To demonstrate its journey and evolution in contemporary style, Bemberg™ has collaborated with MagnoLab to develop a project that resulted in contemporary cut I-shirts presented both in sheer and blends with other certified fibers, including GOTS cottons and RWS wools, capable of enhancing both the hand of the final garment and the performance of the yarn.

The project conceived for Pitti Uomo 102 stems from the spirit of Bemberg™ and fits perfectly into the philosophy of MagnoLab, whose mission is to carry out projects related to environmental responsibility through a joint and participatory approach of partners, and to create value by developing innovative products and processes with rapid testing cycles, according to a lean management model.

As a leading company in the collecting, sorting, reselling and recycling of post-consumer textile waste, TEXAID has enabled the recycling of post-consumer textile waste into new textiles and clothing. After two years of development, the company has developed a fabric including 50 % of post-consumer textile waste from used clothing, collected and prepared for recycling by TEXAID.

Today’s linear system of «take – make – waste» needs to change. New textiles are produced, used and discarded instead of putting them to a second use. The production of new textiles requires natural resources that are limited, and the current system has a significant negative impact on our planet. The transition to a circular system, where garments are kept in use for longer, is an opportunity to harness untapped potential around customer loyalty, economic growth, and ecological sustainability.

To move away from the linear system and enable products to be made out of post-consumer textile waste, TEXAID invested in the textile-to-textile recycling and product development.

Collaboration enables recycling
After two years of research, product development, and most important, building partnerships in the value chain, TEXAID has been able to develop a fabric made of 100 % recycled fiber in close collaboration with our value chain partners.

The fabric is a blend of 50 % post-consumer textile waste that TEXAID has collected in Germany and Switzerland. White cotton textiles which cannot be worn, have been sorted out in a sorting facility in Apolda, Germany. The other 50% is made from ocean-bound plastic waste which is plastic with a high risk of entering the ocean which has been saved and recycled by Unifi. The fabric and bag have been produced in Italy. The cotton material has been shredded by Marchi & Fildi in Biella, IT, who then spun the recycled cotton and recycled polyester fibers into a yarn. This yarn has been woven into a fabric by Tessitura Casoni.T.F.C.

Through this proof of concept, it has been showcased that making fabrics of 100 % recycled content and with 50 % of post-consumer textiles is possible. TEXAID is looking for strong industry partners to push high-value textile to textile recycling technologies in joint projects like these.

Albini Group, historic manufacturer of high-end shirting fabrics, meets C.L.A.S.S. Eco Hub, international platform for the promotion and development of innovative and sustainable textiles. Two groundbreaking companies joining forces in the name of ethical and technological development through the C.L.A.S.S. Material Hub, the section dedicated to fibers, threads, yarns and fabrics that are changing the fashion and textile industry.  The values in which Albini Group believes and the strong sensitivity to environmental issues have led the company to also address the issue of the risk of toxic and harmful chemicals in a systemic way, integrating into the production cycles activities and controls aimed at gradually eliminating their presence, with the clear objective of protecting man and the environment.

Three main research areas - innovative fibers and yarns, sustainable dyes and green chemistry - united by the task of transferring cutting-edge technologies through open innovation. Among the new projects presented is "Off the Grain," born from the collaboration with Riso Gallo, a leading rice producer in Italy. It is a new type of dye derived from the processing of a particular variety of black rice: the boiling water of the rice, which can no longer be used for the food industry, is transformed into a natural dye, resulting in significant water savings during the dyeing process.

"Grounded Indigo" is a natural textile dyestuff, born from the search for dyeing practices that are more responsible to people and the environment. For this project, ALBINI_next chose to collaborate with Stony Creek Colors, an American producer of the world's only 100% plant-based indigo that is USDA BioPreferred certified.

The third project, called "HempFeel," is an innovative hemp oil-based finishing, tipically used for cosmetic products. ALBINI_next was the first company to apply it to fabrics of different weights, compositions and structures. HempFeel replaces silicones usually used in finishing, thus reducing the release of microplastics and giving fabrics a soft and durable hand.

"When discussing values related to creativity, next-generation production and commitment to ethics and traceability, Albini is an extremely important point of reference." says Giusy Bettoni, founder and CEO of C.L.A.S.S. "This is why we are delighted with its inclusion within our Material Hub, alongside its colleagues of the responsible innovation movement. Follow us on this new common path. Next- generation solutions and nice surprises will not be missed."

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC – technological quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

• ROICA™ V550 by Asahi Kasei for its responsible RF (Residual Free) line

Innova Fabrics, the Italian manufacturer of knitted fabrics for apparel, underwear and sports, confirms its choice of ROICA™ by Asahi Kasei, the Japanese leader of premium stretch fiber, for its new responsible line RF (Residual Free).

Despite the deep-rooted history of the company's team in the world of textiles, Innova Fabrics is a reality that is not afraid to innovate with a focus on environmental sustainability. As a result of its push for local production and attention to third-party sustainability certifications (including OEKO-TEX Standard 100, one of the world's best-known labels for textiles tested for harmful substances), Innova Fabrics continues its promise of responsibility with an enrichment of its conscious proposals. In the last season, Innova has increased its smart proposition by launching the RF (Residual Free) line, with the aim of reducing the impact of microplastics residues produced by the fashion industry. This is possible thanks to the combination of two responsible ingredients: SENSIL® Biocare by Nilit and ROICA™ V550 by Asahi Kasei.

SENSIL® BioCare is the premium, sustainable nylon 6.6 fiber enriched with a special technology that helps reduce the persistence of textile waste in the ocean and landfills by acting during and after the product's life cycle. Therefore, if the microplastics in SENSIL® BioCare garments are released during washing, they will decompose much faster than conventional Nylon 6.6 fibers, reducing textile waste. ROICA™ V550, part of the ROICA Eco-Smart™ family, is the premium, sustainable stretch yarn that degrades without releasing harmful substances into the environment, according to the Hohenstein's environmental certification. ROICA™ V550 also carries the Gold Level Material Health certificate from the Cradle-to-Cradle Product Innovation Institute, which evaluated the yarn's impact on human and environmental health. The strong relationship established between Innova Fabrics and ROICA™ by Asahi Kasei is a long-standing one: from the very beginning, the textile company chose ROICA™ as its main reference for premium stretch, using ROICA Colour Perfect™ in most of its articles. Having experienced the innovation of the ROICA™ line dedicated to high-quality color, Innova decided to opt for the ROICA Eco-Smart™ line as part of the extension of its environmentally conscious line.

Thanks to the constant synergy with its premium partner in innovative and responsible stretch, Innova continues its path towards a textile and fashion industry that respects the planet, without forgetting profit. And this is just the beginning. Innova Fabrics pieces containing SENSIL® BioCare and ROICA™ V550
