From the Sector

High-performance yarns now offer almost unlimited possibilities for replacing traditional raw materials in a vast range of technical applications. Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ – finding new uses in sectors such as automotive, aviation, maritime, medical and construction, among many others.

Technical textiles are everywhere in our daily lives today, even if we may not always realize it. Some are in more obviously textile products, from sewing threads to artificial turf. But then, take cars as an example: modern vehicles are stuffed with parts made from sophisticated yarns. It’s common for producers of automotive parts now to send template material and requirement lists to Swiss Textile Machinery members, trusting their expertise and experience. Members operate development and testing centers with latest machine installations, where their experts devise customized solutions, as well as calling on the pure innovative spirit which is part of their DNA.

At the extremes
Technology drives applications beyond our current imagining in the case of Heberlein air splicers. Developed for a wide range of uses with high-strength technical fibers, they have no problems splicing aramid fibers up to 16’100 dtex, carbon up to 30’000 dtex, Dyneema up to 5’500 dtex, and glass up to 4’800 tex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of material without interfering knots.

Retech has the technology to achieve specifications for filament yarns, drawing and stretching fibers to perfection. Top heated godet rolls – many customized – are developed for high-performance fibers. Temperatures up to 400 °C can be achieved. Combining the right settings and wide speed ranges for each specific process results in unique end-products.

Fabric producers of high-end applications must avoid any quality risk. Yarn producers are well aware of this responsibility, so they use precision package winders for technical yarns, developed by Rieter’s subsidiary SSM. Taking yarns from ring twisting bobbins, its specialist finish winders can produce coarse-count technical yarns up to 50’000 dtex, offering a new level of flexibility and winding quality.

Lifestyle essentials
At first glance, motorists might fail to notice many of the technical yarns ‘hidden’ inside their cars. These products have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour, for example, arises from the choice of textile material and the special construction of the yarns used.

Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are needed for vehicle products such as tire carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.

Technical yarns also play a surprising role in our mobile devices. Tapping, scrolling and swiping are second nature for billions, with our phones and a plethora of other lifestyle essentials. Yet, how many people would know that the touch-sensitivity we take for granted on these screens is largely made possible by twisted glass fibers. Bräcker, part of Rieter’s components business, offers a selection of vertical sinter metal rings and nylon travelers for glass fiber twisting, so that mills can achieve high levels of productivity and quality.

Future unlimited
Automotive and communication technology are already important industries for Swiss Textile Machinery members, along with well-known technical textiles markets in sectors such as medical, transport and construction. Smart-wear is already noted as a field with significant potential. Naturally, members are constantly investigating other possibilities. Swiss textile machinery is already applied in energy (batteries), and plastics.

The Swiss Textile Machinery Pavilion will be at the Techtextil exhibition in Frankfurt, Germany, taking place from 21 to 24 June 2022.

According to the United Nations Conference of Trade and Development, the fashion and textile industry represents one of the major polluters of water in the world, with an estimated 93 billion cubic metres of water used per year.

On the occasion of Water Day, C.L.A.S.S. CEO and Founder Giusy Bettoni talked to Sensil® BioCare, Kornit, Ecoalf and Unesco on how their strategies and processes can preserve our most precious, yet limited resource.

Key Takeaways from the Speakers:
"The ocean is absolutely crucial for the survival of this planet, since it almost covers 71 percent of its surface. Writer Arthur Clarke once said: how inappropriate is to call this planet earth, when it is clearly planet ocean."
- Francesca Santoro, Programme Specialist at IOC UNESCO Regional Bureau for Science and Culture in Europe

"Sensil® BioCare is our solution to reduce the persistence of textile waste in the ocean. We embedded technology in it so that if any microfiber is released in the washing, they will break down faster than conventional nylon. Based on an external study, we have seen an almost 60 percent microplastic reduction in two years"
- Michelle Lea, Vice President Global Marketing at Nilit

"When it comes to our printing processes, almost no water is in use and the waste is minimal. We have never seen this before in this industry. Based on LCA tests, when compared to screen printing our "Atlas Max" printer saves up to 93 percent of water, while the "Presto" printer saves up to 95 percent of water".
- Michal Arbel, Sustainability Communication Lead at Kornit Digital

"One of the most important projects of the company is Upcycling the Oceans, with the aim of tackling the marine litter in collaboration with the fishing sector. Last year, we collected 300 tons of litter from the seabed, and we promoted circular economy by transforming the waste in products."
- Irene Diez, Director at Ecoalf Foundation

Zahnbürsten, Gitarrensaiten, Damenstrümpfe, Fallschirme: Es gibt fast nichts, was man aus Nylon nicht herstellen könnte. In den USA entwickelt, waren diese Polyamide (chemisch: Polyhexamethylenadipinsäureamid) die ersten vollständig synthetisch hergestellten Fasern. Rohstoff damals wie heute: Erdöl. Toray ist es nun gelungen, eine Nylon-510-Faser aus rein biobasierten synthetischen Polymeren herzustellen. Ecodear™ N510 ist die erste zu 100 Prozent pflanzenbasierte Nylonfaser in der Ecodear™-Produktpalette von Toray.

Ecodear™ N510 richtet sich an High-End-Märkte, wo Kunden großen Wert auf Nachhaltigkeit legen. Die Fasern sind in erster Linie für Sport- und Outdoor-Bekleidung gedacht, können aber auch in leichter Unterwäsche sowie Spitzenstoffen verarbeitet werden.

Toray plant den Verkaufsstart von Textilien aus Ecodear™ N510 für Herbst/Winter 2023. Bis Ende März 2023 soll das Produktionsvolumen 200.000 Meter betragen und bis März 2026 auf 600.000 Meter anwachsen. Der Verkauf von Ecodear™ N510-Fasern soll dann im Herbst/Winter 2024 starten, bis März 2024 erwartet das Unternehmen eine monatliche Produktion von drei Tonnen.

Toray entwickelte Ecodear™ N510 durch Polymerisieren und Spinnen von Sebacinsäure aus Rizinusöl und Pentamethylendiamin aus Mais. Im Gegensatz zu anderen Nylonsorten auf rein pflanzlicher Basis hat Ecodear™ N510 einen hohen Schmelzpunkt und eine hervorragende Dimensionsstabilität. Außerdem ist es genauso stark und hitzebeständig wie Nylon 6. Unternehmen können so nachhaltige Produkte herstellen, ohne bei den Eigenschaften Abstriche machen zu müssen.

Für Toray ist Ecodear™ N510 aber nur der Anfang. Das Unternehmen arbeitet bereits an dünneren und leichteren Fasern sowie an Varianten mit einer anderen Form des Faserquerschnitts, was Textilien besondere Eigenschaften verleihen wird. Damit erschließt Toray neue Anwendungen für Bekleidung und technische Materialien und unterstützt die Transformation zu einer nachhaltigen Gesellschaft. Die Toray-Gruppe hat sich das Ziel gesetzt, bis 2050 Kohlenstoffneutralität zu erreichen und zur Lösung von Umweltproblemen auf der ganzen Welt beizutragen.

Legend has it that a sailor brought his beloved a seaweed from distant seas as a gift. The woman, wanting to preserve its beauty, replicated the design and holes with needle and thread. And so lace was born. Since that moment, lace has lived within the walls of churches and castles, visited race tracks and catwalks, changing shape and color according to seasons and times.

Among the companies involved in writing a new chapter in the history of lace, Iluna Group definitely stands out. Founded in 1970 from an idea of its founder Luigi Annovazzi, over the years Iluna has responded to the challenges posed by the market in terms of technology and sustainability.

Since 2017 Iluna has been using only sustainable and certified ROICA™ stretch yarns from the ROICA Eco-Smart™ family, while the percentage of sustainable references has risen from 3% in 2018 to 52% in 2021.

Two Italian companies committed to the transition to an ecological industry and presented the results of their collaboration at the Blue of a Kind shop in Milan. A union of intent that has led to a partnership initially born remotely, in the middle of the difficulties of recent years, finally set off through the live painting performance by Erik Varusio. The artist from Vicenza, well-known in the world of fashion and illustration, has customized a selection of Blue of a kind’s t-shirts using the sustainable Officina+39's Recycrom™ dyestuff.

Revolution of existing
Blue of a kind is meant to be not just a fashion company, rather a community built around an idea: to combine uncompromised style, contemporary fit and products with a valuable heritage, and a sustainable production process. The products are made exclusively from vintage products handcrafted with the use of scrap fabrics and surplus, thanks to a network of suppliers all over Europe, which makes it possible to find the best vintage garments and stock, ultimately becoming the raw material to lead a luxury revolution, chic yet sustainable.

Fashion and sustainable chemicals
The mission of Blue of a kind perfectly matches with the technologies of Officina+39, a Biella-based company for which the word “waste” becomes synonymous with opportunity, a source for creating something new, encouraging circularity and reducing environmental impact. From this vision comes to be Recycrom™, a revolutionary and sustainable dyestuffs range, patented, which employs recycled used clothing, fibrous material, and textile scraps: its full range of pigment powders is obtained through a cutting-edge upcycling process that involves textile fibers from used clothing and manufacturing waste for dyeing and printing on cotton, wool, nylon or any cellulosic and natural fiber or blend.

Shared goals
Both companies firmly believe that the present and future of the fashion industry lies in circularity and upcycling without compromise. The sector has been hit hard in recent years by the pandemic and the difficulty in finding raw materials, but opportunities have been generated to think about new partnerships and initiatives, to focus on available resources and real needs, and to invest in sustainable technologies for change.
Being part of this change is the goal shared by Blue of a kind and Officina+39, starting with concrete contributions and more transparent, sustainable, durable and quality products.

• RadiciGroup and DKB introduce the first “circular” ski suit
• A garment made of yarn obtained from recycled materials and designed with end-of-life recyclability in mind, without compromising style, design and technical performance.
• RadiciGroup Ski Club athletes will be the first ambassadors of this sustainability project

The first truly sustainable ski suit, featuring Italian style and design and a zero-kilometre supply chain, is finally here. Two Bergamo companies of excellence played the leading roles in the conception and realization of this highly innovative fashion-sport garment: RadiciGroup, a world leading producer of chemical intermediates, polyamide polymers, high-performance engineering polymers and advanced textile solutions, and DKB, a company specializing in technical sportswear with the same brand name.

The ski suit, consisting of jacket and trousers, is fashioned with a fabric made of RENYCLE, a RadiciGroup yarn obtained from mechanically recycled polyamide (nylon), which affords notable savings in energy and water consumption, as well as lower CO2 emissions. In addition, the suit’s padding and numerous accessories, such as zippers, Velcro, buttons and thread, are also made of polyamide.

This achievement was made possible by the great teamwork of RadiciGroup and DKB on the research and development of chemically compatible materials that can be used in special applications requiring high technical performance. The end result is an almost mono-material garment that significantly facilitates end-of-life recycling. It can be more easily converted into polymers for use in the manufacture of ski boot components and bindings, in addition to applications in the automotive and furnishing industries, or in any other sector requiring the characteristics of high performance polyamides.

The ski suit by RadiciGroup is thus an all-round application of ecodesign and circular economy principles to fashion and garment making, which justifies the claim “Una sostenibilità all’altezza delle nostre montagne” [Sustainability worthy of our mountains] written in a logo patch on the inside of the jacket.

“I am particularly proud of this achievement, a synthesis of my passion and effort,” said Angelo Radici, president of RadiciGroup. “I’ve always loved mountaineering and skiing, and, together with my collaborators, I work hard at our company day in and day out to find innovative solutions that improve the sustainability of our industry. This ski suit is concrete proof of the fact that textiles and apparel can be made sustainable without compromising on comfort, design, looks or performance. I will never get tired of repeating that collaboration among the firms along the production chain is crucial to manufacturing goods with an ecodesign approach, considering their end-of-life recyclability and, thus, potentially giving them unlimited durability. Upstream producers, like us, gladly share our know-how in materials chemistry and experience in recycling with our downstream partners, so that, together, we can find sustainable and viable solutions in the various sectors where we operate.”

• Focus now on digital fair platform

The PERFORMANCE DAYS team regrets having to cancel at short notice the physical edition of PERFORMANCE DAYS which was scheduled to take place on December 1-2, 2021 at the Messe München exhibition center. Right up until today, the event organizers of PERFORMANCE DAYS were in the final stages of preparations for the fair. The goal of being able to realize a fully booked fair with a portfolio like in pre-pandemic times seemed to be within reach. The political regulations agreed in Bavaria from November 19, 2021 and the heavily restricted constraints associated with an incidence of 1000 have far-reaching consequences for PERFORMANCE DAYS. As a result of the current sharp rise in the number of infections in Munich, the planned winter edition must now be cancelled as a precaution. The focus now is now completely on the digital fair on December 1 and 2, 2021.

The new measures are scheduled to come into effect in Munich from the middle of this week, which would lead to very short-term changes. The organizers of PERFORMANCE DAYS therefore see themselves in the responsibility to enable a minimum of planning security as well as a responsible handling of the given situation with this decision.

“Exceptional situations require exceptional decisions – making these all the more difficult. After experiencing a very successful and surprisingly well-attended fair with the Functional Fabric Fair by PERFORMANCE DAYS in Portland, Oregon last week, we have tried everything possible up to the last moment and firmly believed that we would finally set a further positive milestone with the physical edition of PERFORMANCE DAYS in Munich. We fulfilled all the requirements, updated our hygiene concept several times to comply with the dynamically changing measures and took all the necessary precautions for a safe event. Unfortunately, current developments do not allow us to host the trade fair event next week, since the undisputed top priority is the protection and health of our visitors. Now our focus turns to the full implementation of the Digital Fair on December 1 and 2, 2021”, explains Marco Weichert, CEO of PERFORMANCE DAYS

Focus on digital platform
The PERFORMANCE DAYS team is now investing all its efforts into implementing the Digital Fair on December 1 and 2, 2021. As part of THE LOOP, those interested have the opportunity as of now to view online the fabric innovations and news for the Winter Season 2023/24, this year’s Focus Topic “Sustainable Nylon” and the latest color trends. In the Marketplace, visitors will be able to view the numerous exhibitor products, including the PERFORMANCE FORUM’s curated sustainable fabric highlights. In order to present the fabrics to visitors as realistically as possible in terms of feel, design and structure in digital form, the PERFORMANCE FORUM has been equipped with new 3D-technology, including innovative tools such as 3D images, video animations and downloadable U3M files. Throughout the Digital Fair, exhibitors and fair visitors can look forward to extensive networking opportunities. For example, as part of the extensive digital supporting program on December 1, with various expert talks, discussion rounds and speakers via livestream, moderated by Charles Ross live from the studio. On December 2, the “sustain & innovate” conference on this year’s Focus Topic “The Sustainable Future of Nylon” will kick off with discussions and panels, moderated by Astrid Schlüchter, Editor-in-Chief of SAZsport and SPORTSFASHION by saz.  

A very special thank you goes out to the entire PERFORMANCE DAYS community with its exhibitors, visitors and partners for their active support, trust, loyalty and understanding in these still extraordinary times. The team looks forward to the Digital Fair on December 1 and 2, 2021 and further ahead to meeting you all personally on April 27 and 28, 2022 at the summer edition of PERFORMANCE DAYS live in Munich.

RadiciGroup demonstrates the feasibility of industrial-scale production of polyamides (nylon) starting from bio adipic acid obtained from renewable raw materials, including waste oil and by-products of the oil industry. Potential application sectors for the process and products are textile/fashion, automotive, design, electrical and electronics.

The research was conducted through the Ulysses project and experimentation was performed in collaboration with research centres and universities. Partial funding was received from the Region of Piedmont, within the scope of the “Call for Proposals IR2 (Industrialization of research results)”. The ambitious, innovative multiyear project was launched in March 2018 and stemmed from RadiciGroup's desire to increase the sustainability of its products, whilst delivering the same quality and performance as required by product standards. What is more, the Group wanted to meet the demand coming from its various strategic sectors, in line with the European targets for the development of low-emission businesses and a circular economy.

• A paper published in ACS Applied Materials Interfaces details effectiveness, describes protocol for future testing

An international team of scientists and engineers from the University of Cambridge, the Icahn School of Medicine at Mount Sinai, ResInnova Labs and Ascend Performance Materials has found that a nylon fabric embedded with zinc ions successfully inactivated 99% of the viruses that cause COVID-19 and the common flu.

Face masks, protective clothing and filters are used to slow the spread of viruses. But poor-quality masks can harbor active viruses from infected wearers, posing a transmission risk.

“A major challenge is absorption and inactivation,” said Vikram Gopal, Ph.D., co-senior author and chief technology officer at Ascend Performance Materials. “Respiratory viral illnesses, such as COVID-19, and the flu, are transmitted through droplets and aerosols. Polypropylene, the material in commonly used disposable masks, is a hydrophobic plastic and does not absorb moisture. Instead, the viruses can sit on the surface of the mask, posing a transmission risk when the mask is handled.”

Cotton also has problems, Dr. Gopal said. “Cotton effectively absorbs moisture, but it doesn’t inactivate the virus – again, posing a transmission risk,” he said. In the paper published in ACS Applied Materials Interfaces, the researchers described how a fabric made of nylon 6,6 embedded with active zinc ions absorbed virus-containing moisture droplets and effectively inactivated the particles. The fabric produced a 2-log, or 99%, reduction of virus particles in one hour.

The research team also was able to demonstrate that nylon with active zinc ions remains stable over time, keeping its virus-inactivating properties after 50 washes. “The study shows how nylon textile fabric with zinc outperforms the widely used cotton and polypropylene materials at virus absorption and inactivation,” Dr. Gopal said. The findings have significant implications for future development of PPE, Dr. Gopal said. “Pathogen-free PPE does more than just cut down the risk of transmitting the virus,” Gopal said. “By making PPE washable and reusable, you reduce the need for single-use products, keeping hundreds of millions of masks out of landfills.”
