From the Sector

Freudenberg Performance Materials (Freudenberg) is endorsing further sustainable products with its ECO-CHECK label introduced last year. These products comply with various environmental criteria. With immediate effect, five more solutions bear the label making the company’s commitment to sustainability visible.

Leather goods
The newly-endorsed ECO-CHECK products include one Evolon® microfilament textile application. This is a reinforcement material for leather goods that is manufactured with no solvent and no binder. It contains up to 80 percent recycled PET and is suitable for a broad range of applications. The material is produced at Freudenberg’s facility in Colmar, France, where the manufacturing process is highly sustainable: it is certified to STeP by OEKO-TEX® and fully complies with the DETOX TO ZERO by OEKO-TEX® criteria.

Healthcare applications
In the field of healthcare, the bio-based M 1714 wound pad with superior absorption for more challenging wounds has now been endorsed with the ECO-CHECK label. The dressing consists of a mix of bio-based fibers derived from natural sources and exhibits a smooth wound contact layer. The product has been evaluated for industrial compostability and conforms to ISO 13432.

Architectural applications
The sustainable TF 400 Eco F mesh fabric for textile architecture from Mehler Texnologies® now also bears the ECO-CHECK label. Its yarn is made of 100% recycled PET bottles and its characteristics are very similar to those of conventional mesh fabrics. In 2021, it was awarded first place by the Architectural Membrane Association (AMA) in the “product” category in recognition of its properties.

Shoes
In the shoe industry, the binder-free strobel insoles have been endorsed as particularly sustainable. They contain a high percentage of recycled green bottle flakes. Moreover, the insoles themselves are fully recyclable.

Filtration applications
The two layered, needle-punched nonwoven filter medium that has just been endorsed with the ECO-CHECK label has impressive sustainability characteristics. Made entirely of polyester, more than half the fibers consist of recycled material.

People in Brazil have a new ally in the fight against an invasive carrier of dengue fever – a mosquito-repellent coating developed by AkzoNobel’s Coral brand.
 
Known as Well-being Protection Anti-Mosquito, the colorless matt varnish contains an active ingredient called permethrin. Its repellent action is specifically designed to combat the Aedes aegypti mosquito, which was largely responsible for dengue cases in Brazil surging 165% during the first few months of 2022 – according to figures from the Brazilian Ministry of Health. As well as spreading dengue, Aedes aegypti can also transmit the zika and chikungunya virus.
 
When a mosquito lands on the new transparent topcoat, the permethrin is absorbed through its feet and over-excites the insect’s nervous system, causing it to disengage or fall off. Permethrin is a well-known repellent and is commonly used in fabrics for mosquito nets and protective clothing.

The effectiveness of Well-being Protection Anti-Mosquito was tested in an independent external laboratory, certified by the Brazilian Network of Analytical Laboratories in Health. All the tests took place on painted walls and ceilings in a life-size house environment and successfully proved that mosquitoes were repelled from the room after contact, with the active ingredient being retained in the varnish matrix.

Huntsman Textile Effects, a global leader in innovative solutions and environmentally sustainable products, will be at Outdoor Retailer in Denver, Colorado this week to present end-to-end solutions that enable outdoor apparel brands to achieve the functionality that outdoor adventurers crave with on-trend aesthetics and a high degree of sustainability.

Huntsman will highlight the AVITERA® SE Fast process. This technology delivers the lowest environmental impact for dyeing polyester-cellulosic (PES-CO) blends. It combines alkali-clearable TERASIL® W/WW disperse dyes and AVITERA® SE reactive dyes to cut processing time from around nine hours to just six, helping mills to reduce the water and energy required for production by up to 50% and to increase output by up to 25% or more. The new process also delivers outstanding wet-fastness to ensure that sportswear will not bleed or stain during home laundering or while in storage or transit.

EROPON® E3-SAVE is another next-generation water-saving innovation. An all-in-one textile auxiliary for PES processing, it allows pre-scouring, dyeing and reduction clearing to be combined in a single bath and eliminates the need for anti-foaming products, which shortens processing time and further saves water and energy.

Eco-friendly stain and rain resistance
Huntsman will also present eco-friendly finishes that repel water and stains to help garments look new for longer. Continuing its long-standing relationship with Chemours, Huntsman is highlighting Teflon™ EcoElite with Zelan™ R3 technology. The industry’s first renewably sourced water-repellent finish, it contains 63% plant-based materials and exceeds performance levels possible with traditional fluorinated technologies, preserving breathability while offering excellent water repellency and durability.

Another breakthrough for brands and mills is PHOBOTEX® RSY for outerwear. A next-generation non-fluorinated water-repellent finish, its performance is comparable to formulations based on per-fluorinated chemicals (PFCs), delivering sustainable protection that keeps the wearer dry, even in the most demanding environments. It is a perfect combination of excellent water repellency and extremely high wash durability.

Innovative odor control solutions
Huntsman will also showcase antimicrobial and odor-control solutions as part of its partnership with Sciessent. Sciessent’s latest anti-odor technology, NOBO™, has been specifically developed to reduce odors in natural and synthetic fabrics. It can be incorporated into virtually any fabric, making it ideal for everything from base layer and activewear tops to socks and underwear to hiking pants, chinos and hard shell jackets. It offers a cost-effective way to upgrade everyday garments.

In addition, the partners will also present Sciessent’s Agion Active X2®, a next-generation odor-control solution that combines advanced antimicrobial and odor-absorbing technologies to both capture and fight odor-causing bacteria, and Lava X2®, a standalone odor adsorption product and key component of Agion Active X2® that attracts, adsorbs and degrades odors for long-lasing odor protection.

• Freudenberg presents liquid absorbers for lithium-ion battery packs

The experts from Freudenberg Performance Materials (Freudenberg) will be presenting battery pack liquid absorbers, an innovative solution that makes battery systems safer, at this year's Battery Show in Stuttgart. The absorbent pads capture and store unwanted liquids inside the packs quickly and reliably. With adjustable absorption capacity and geometries, battery pack liquid absorbers ensure long-lasting battery packs. Visitors will find Freudenberg at Stand C 36 in Hall 10 from June 28 to 30.

Battery packs are the core elements of mobile and stationary lithium-ion energy storage systems. They are used in automotive and industrial applications. The performance and lifespan of these components are largely responsible for the efficiency of the energy storage system. Moisture inside the packs, such as condensation water or leaking coolant, can considerably diminish both function and lifespan. Battery pack liquid absorbers act as a safety system: the special fleece quickly takes up condensate or coolant and stores it effectively.

Standard & Poor's Global Ratings (S&P) raises its long-term rating for SGL Carbon to B- and its issue rating on its financial instruments to B. The outlook for the company is rated as stable by the renowned rating agency.

S&P Global Ratings explains the upgrade of SGL's rating with the company's improved capital structure and the reduction of net debt. The rating agency expects SGL Carbon to generate positive free cash flow in the coming years, which will support the reduction in absolute debt.

For the future development of SGL Carbon, S&P assumes an improvement in profitability based in particular on the expansion of products and materials for the future-oriented core markets of mobility, energy transition and digitalization, besides the savings from the restructuring.

"We are pleased that our operational successes and the already advanced trans-formation of SGL Carbon have been honored by the two major rating agencies - Moody's and S&P - by upgrading the ratings. We also see this as a motivation for the further development of SGL Carbon," explains Thomas Dippold, Chief Financial Officer of SGL Carbon SE.

The orders index for textile machinery for the first quarter of 2022, processed by ACIMIT, the Association of Italian Textile Machinery Manufacturers, shows a slight decrease (-4%) compared to the same period from January to March 2021. In absolute value, the index stood at 117 points (basis: 2015 = 100).

On the domestic front orders shrank by fully 22%, whereas abroad the decline was more contained (-2%). The absolute value of the index in Italy was set at 136 points. On foreign markets, the index scored a value of 114.9 points.

ACIMIT President Alessandro Zucchi commented that: “The global pandemic and Russian-Ukrainian conflict have accentuated the climate of uncertainty for the whole of the textile industry. Criticalities already present in the past year (such as a sharp rise in prices of raw materials and their scarce availability, as well as increased transport costs) are now accentuated more than ever. While orders appear to have settled on foreign markets, domestically, following a strong recovery in 2021, we now have to deal with a general negativity permeating the Italian economy.”

The ongoing conflict in Ukraine, together with successive pandemic lockdowns in the main market for textile machinery manufacturers, namely China, have undermined the confidence of Italian companies in the sector. “I believe 2022 will be a transition year for the industry, as we await a calming international economic scenario. In the meantime,” adds Zucchi, “our association continues to work to strengthen the positioning of Italy’s textile machinery industry worldwide through promotional initiatives in collaboration with Ministry of Foreign Affairs and International Cooperation and Italian Trade Agency.”

The latest of these initiatives was carried out at the end of April, with the opening of an Italian technology training center for textile machinery in Mongolia, a Country that ranks among the world’s leading producers of raw cashmere. ACIMIT’s president concludes that, “With the training center starting its operations, our sector is laying the foundations for further business opportunities in an emerging market. I’m certain the initiative will bear a return in terms of image not only for individual Italian companies who are participating by supplying machinery, but on the entire Italian textile machinery sector as a whole.”

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.

• New technology for marine composites proven to reduce time and cost in manufacturing through out-of-autoclave processing

Hexcel Corporation (NYSE: HXL) has developed a new technology for out-of-autoclave (OoA) processing that delivers a game-changing reduction in process time and cost for marine manufacturers without compromising mechanical performance. Hexcel has leveraged its experience in aerospace and wind energy to develop its new G-Vent technology for OoA processing of highly loaded, thick section marine structures such as masts, foils, and wind-assisted ship propulsion (WASP) components. Hexcel’s full range of marine prepregs are now available with integrated G-Vent technology, reducing the requirement for debulking steps and ensuring extremely low porosity (<1%) irrespective of the laminate thickness.

To evaluate the new technology, Hexcel completed a test program with Q.I. Composites, a world leader in non-destructive testing in performance marine applications. The program evaluated HexPlyÒ 40- layer prepreg samples prepared with G-Vent technology. Carbon fiber panels made with no debulking revealed approximately three times less porosity than those using a typical 10-minute debulk with every second ply. Ultrasonic and CT scan analysis by Q.I. Composites confirmed the void content results with porosity levels in line with state-of-the-art autoclaved carbon prepreg foils. Key tensile, compressive and interlaminar shear strength results were also higher for the G-Vent panels.

“We evaluated the quality of thick laminates produced with G-Vent and found that they are comparable to laminates made in an autoclave as per best practice in the market,” said Stefano Beltrando, CEO, Q.I. Composites. “Even more impressive, they were achieved with no debulking.” Tom James, Business Development Manager at Hexcel, said, “We are absolutely delighted with the feedback from Q.I. that confirms our own test data and positions G-Vent technology as a leading OoA process enabler for high-performance thick laminate structures. G-Vent provides a faster and more cost-effective manufacturing route for large marine structures with absolutely no compromise in mechanical performance.”

Sitip confirms for the third year its partnership with SCOTT Racing Team in the production of the team uniform created in collaboration with ROICA™ EF of Asahi Kasei and Rosti.

The partnership was born in 2019 and celebrated during Ispo 2020, which returns for the third consecutive year to re-propose an exclusive and special uniform, designed to be extremely performing but also, and entirely, eco-sustainable.

Starting from the performance requirements of athletes, who need highly technical fabrics extremely breathable, comfortable on the skin, resistant and with perfect shape retention able to support them in competitions, Sitip has chosen the fabrics of its Native Sustainable Textiles line - technology which applies to fabrics produced with recycled yarns and chemicals with low environmental impact, implementing the GRS (Global Recycle Standard) standard, with Asahi Kasei’s premium ROICA™ EF stretch yarn.

This line includes NATIVE-BICIMANIA and NATIVE-PIRATA, two GRS-certified recycled polyester fabrics chosen for the production of the uniform shirt, enriched by Microsense Soft Performance technology - able to guarantee the product a delicate softness and maximum comfort on the skin.

This year the absolute novelty is represented by the shorts, for a complete uniform: made with the NATIVE-THUNDERBIKE POWER fabric, designed for high performance sports, in recycled polyamide and always with the ROICA™ EF yarn by Asahi Kasei.
