From the Sector

Toray Industries, Inc., announced that it has combined nanotechnology and fiber technology to create a cross-shaped polymethyl methacrylate (PMMA) nanopore fiber that efficiently adsorbs pathogenic proteins in the blood.

The company developed this fiber by employing its PMMA hollow fiber membrane spinning technology. Changing the nanopore size on the surface and inside the fiber makes it possible to control the types of protein that this material adsorbs. This could become a fundamental blood purification technology for a range of protein adsorption columns that cause diseases.

The fiber’s cross-shaped cross section has a larger surface area than fibers with round ones. This provides much better contact between the blood and fiber and significantly enhances protein adsorption efficiency.

Toray is the only company to have commercialized a PMMA hollow-fiber membrane artificial kidney for dialysis treatment. Its new nanopore fiber benefits from PMMA’s good protein adsorption and biocompatibility. Using the structural formation of a stereocomplex from two PMMA types entangled spirally during the spinning process to form the fiber shape, Toray made it possible for the fiber itself to develop pores of several to dozens of nanometers. Depending on the pore size, large proteins cannot go inside the pores. If they are too small, they are not trapped. This enables selective adsorption of moderately sized proteins trapped in pores.

The fiber pore sizes are adjustable to the diameters of target proteins for a range of diseases. These include inflammatory proteins in sepsis, autoantibodies in autoimmune diseases, and causative proteins in chronic illnesses. Toray’s technology is thus fundamental to developing disease-causing protein adsorption columns to purify blood.

Toray’s cross-shaped cross section suppresses inter-fiber adhesion, increasing the surface area per volume and enabling highly efficient protein adsorption. For blood purification applications, higher capacity adsorption columns increase blood removal amounts from the body, which can be especially stressful for the elderly and children. The new fiber’s highly efficient protein adsorption should contribute to compact, high-performance protein adsorption columns.

• ESD protection in harsh environments:
• Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
• Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
• Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.

Fibre Extrusion Technology Limited (FET) of Leeds, England has installed a FET-200LAB wet spinning system at the University of Manchester which will play a major part in advanced materials research to support sustainable growth and development.

• Focus on the guiding principle of "textile intelligence" and sustainability

Long before sustainability became a trend in the textile industry, Schoeller Textil AG, which has been innovating technical fabrics and smart textile finishing technologies for more than 150 years, made it its mission to develop textile innovations in harmony with nature. Now the company is undergoing an extensive rebranding, whilst unveiling its strong brand foundation in the process. The result embodies the newly defined guiding principle of “Textile Intelligence” - the development and successful implementation of innovative textiles and intelligent textile technologies.

Innovations in the textile industry must meet requirements on several levels – offering both new and optimized solutions to sociological, ecological, and economic challenges of our time. Creating this holistic added value is firmly rooted in the Schoeller brand origin and is still the top priority in textile product development today. The brand essence has thus remained the same, but it has been embodied anew.

“At the beginning of the rebranding process, it was clear to us we had to root ourselves in (Swiss) tradition in order to fully realize Schoeller’s entire brand potential and successfully explore new, digital paths,” said Antonio Gatti Balsarri, Schoeller chief commercial officer.

“The goal of the rebranding is to communicate our traditional brand values in a completely new brand presence. The result was a sharpened brand profile, a clear brand strategy and tonality, as well as a clean, modern corporate design. We will specifically address our sustainability commitment through the expansion of digital touchpoints, their cross-media use, and an increased online presence. Simplified, straightforward, sustainable - in accordance with our greatest source of inspiration: nature.”

Transparency and Sustainability
Paramount to Schoeller’s corporate identity is the full disclosure of brand principles and transparency around all business divisions. A simplified logo design was established by reducing logo elements and colors for a modern look and feel that can be produced in a much more resource-efficient manner. Schoeller’s new brand mantra of “Textile Intelligence” speaks to its company mission of more than 150 years.

Schoeller has been a bluesign system partner from the very beginning and uses the Higg Facility Environmental Module (FEM) to assess sustainable performance. In addition to environmentally-friendly manufacturing processes and careful material selection, the highest quality and sustainability standards in production also mean guaranteeing fair working conditions. Schoeller follows a Code of Conduct that guarantees transparent production chains, environmental protection, and fair working conditions.

“Zero Textile Waste” becomes a targeted brand strategy. While the production of textiles and textile technologies is continuously being optimized to preserve resources, the manufacturing processes are often costly and complex. To this end, Schoeller offers new approaches to efforts around Zero Waste in the industry. Its new online shop, “Schoeller re-Fabric” sells textile remnants from production directly to designers and smaller productions to increase its overall production volume efficiency and avoid textile waste.

• Presenting Sustainable Apparel Solutions

Freudenberg Performance Materials Apparel (Freudenberg) will be part of the Performance Days from November 03 to 04, 2022 in Munich, Germany. The specialist in woven, knitted, weft and nonwoven interlinings will showcase the latest sustainable products for sportswear, workwear, sportive fashion and athleisure collections.

Freudenberg will showcase its full range of European and global products being part of its House of Sustainability, Active Range and the comfortemp® brand offering high-performance thermal insulation for outdoor and active wear.

Freudenberg Performance Materials Apparel’s House of Sustainability strives to minimize the company’s footprint by reducing the environmental impact of the company’s manufacturing processes to a minimum. At the same time, Freudenberg maximizes its handprint by developing products enabling customers to manufacture more efficiently and sustainably or to consume fewer valuable resources. This initiative is based on seven product pillars with more than 500 sustainable products, among them recycled general interlinings, recyclable, energy-saving or biodegradable materials, sustainable cotton, nature-based solutions and recycled thermal insulations and linings.

Being part of the House of Sustainability, Freudenberg’s Active Range stands for high-performance solutions for stretch active and outdoor active wear including interlinings, tapes, linings, bonding solutions and measuring tools. Most materials of this portfolio are made of at least 70% recycled materials and thus cater to customers’ sustainability goals.

The identification of profitable new niche markets has been central to the success and continuous expansion of Germany’s Dolinschek, a leading knitting, dyeing and finishing specialist, located in Burladingen in Baden-Württemberg.

“There is so much more to textiles than just clothing,” says Theo Dolinschek, who runs the company with his brother Erwin. “We handle many different technical materials such as automotive components, geotextiles and wallcoverings, but also those for more unusual applications such as inlays for extractor hoods, cut protection fabrics and even wool felts which are employed as insulation on wind turbines.

“We have also recently started to produce compression stockings in a variety of colours, because not everyone wants them black, beige or skin coloured. The most important product areas for us now are in sportswear, corsetry and lingerie, as well as orthopedic and medical products, workwear and protective clothing, but in addition, many other technical applications.”

The Dolinschek brothers moved their business to the historic site of the former Ambrosius Heim textile company in Burladingen in 2001 in order to expand. At the time, the company – founded by their father in 1980 as a textile wholesaler before moving into dyeing – employed just 13 people. Within a year, the company had bought additional space at the site.

Now, with Theo in charge of technology and sales, and Erwin responsible for production, the company employs almost 100 people and operates on an integrated site of 35,000 square metres.

In 2005, a laminating department was established by the company and since 2012 investment in knitting machines has been ongoing.

“The further we went into vertical integration, the more of our own products we were able to position on the market and so we were also able to make ourselves more independent,” says Theo. “We have continued to develop and today we can produce high-quality fabrics for many fields, with 42 knitting machines, 36 dyeing machines, three stenter frames and many other production and processing machines.”

Dolinschek has also developed its own proprietary TMG dyeing machines which have subsequently been successfully sold to many other companies all over the world. There are currently 11 of these machines  in operation at the Burladingen site and around 45 installed at other companies.

For finishing technology, however, the company relies on Monforts, and has installed a new seven chamber Montex TwinAir stenter range with a Montex®Coat coating unit in knife execution, enabling the coating of dimensionally stable knitted fabrics with polyurethane or acrylate. Another unique feature is the Teflon-coated (non-stick) transportation belt through the system.

The Montex line is also equipped with integrated heat recovery and exhaust gas purification to ensure the most resource-efficient processing available on the market. The exhaust air goes from the Monforts heat recovery system into an existing air/water heat recovery system and then into an electrostatic precipitator.

Highly-intuitive Monforts Qualitex visualisation software allows all machine functions and process parameters to be assessed and controlled easily.

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.
