Sensil BodyFresh fabrics reduce viral activity on contact

Knitting fair according to reports, Israeli nylon manufacturer Nilit has recently developed a new type of antibacterial fiber Sensil BodyFresh, which can provide athletes and outdoor athletes with excellent odor suppression, durability and smooth comfort. The yarn is said to inhibit the growth of bacteria like Staphylococcus, St. Hominis, Micrococcus and Coryneforme bacteria, which can cause the human body to emit some unpleasant odors and discomfort.

Although the fine denier fiber can bring a smooth feel, it still has good wear resistance, and it can resist various harsh conditions. The antibacterial additives are in the polymer instead of coating, so the garment can withstand more than 20 washings and still maintain antibacterial properties.

Sensil BodyFresh yarn currently has various denier specifications and can be widely used in outdoor clothing and sportswear, with very good appearance and feel.

The additive embedded in Sensil BodyFresh yarn is said to provide long-lasting protection that does not deteriorate with laundering, indicating that the additive is not washed.

Nilit, a global leader in sustainable, premium Nylon 6.6 for apparel, reports it has received confirmation from Microbe Investigations AG (MIS), a microbiological testing services lab, that fabric made with Sensil BodyFresh demonstrated a 99.85% reduction in viral activity when tested according to ISO 18184:2019 criteria against Betacoronavirus 1 (OC43), an enveloped, positive-sense, single-stranded RNA virus. The additive embedded in the Sensil BodyFresh yarn is said to provide long-lasting protection that does not deteriorate with laundering, indicating that the additive is not washed out of the fabric.

“We originally developed Sensil BodyFresh with antibacterial and anti-odour properties to provide consumers with outstanding freshness,” says Sagee Aran, Head of Global Marketing at Nilit. “With these proven antiviral test results, our business partners can expand their Sensil BodyFresh product concepts beyond comfort and aesthetics to include enhanced protection and a positive sense of well-being.”

Sensil BodyFresh is currently used by leading apparel brands across all segments such as intimates and underwear, base layer, activewear, and legwear. By inhibiting microbial growth, fabrics stay fresher longer and require fewer launderings, Nilit explains. The benefits are built into the yarn and do not wash out or wear off for the life of the fabric, providing sustainable protection that doesn’t pollute waterways, the company adds. In addition to providing these proven antimicrobial benefits, Sensil BodyFresh is, Nilit says, responsibly made at its water and energy optimized facilities and meets Nilit’s Total Product Sustainability guidelines for long-lasting, high quality products made with respect for the planet and people.

“Consumers today appreciate long lasting, environmentally responsible, multifunctional apparel,” continues Aran. “Sensil BodyFresh offers numerous performance factors that include sustainability and well-being attributes for today’s current climate.”

Nilit says it has a broad portfolio of sustainable Sensil premium Nylon products that address water preservation, energy use reduction, pollution elimination, biodegradability, and increased use of recycled inputs. Nilit is committed to providing the industry leadership and the products that help the apparel world use more sustainable fabrics in more responsible ways, the company concludes.

“Manmade fibres are durable, versatile and cost-effective. That’s why they have become indispensable in yarn production over the past decade and now account for more than 40% of staple fibre consumption,” says textile machinery manufacturer Truetzschler. Accordingly, the German company has supported this trend by developing highly specialized machines for manmade fibres that meet constantly rising expectations for quality and efficiency – and its TC 19i is now winning over customers worldwide, Truetzschler says.

The intelligent card TC 19i for manmade fibres was launched in 2019 and is now the international benchmark for manmade fibre processing. The results from major textile markets across Asia, Europe and the Middle East speak for themselves: customers were able to increase productivity by between 20% and 100%, while also improving quality (IPI) by between 20% and 55%, adds Truetzschler.

Its processes include ring, compact, air jet, open end, core spun and siro spun technologies. Experts at Acarsoy Tekstil were initially sceptical when Truetzschler TC 19i cards were installed in the second air jet line for 100% viscose yarn (Ne 20 to 28). General manager Bülent Değirmencioğlu, as well as his team of operations and maintenance managers, were unsure whether the required level of quality could be maintained when the TC 19i operated at such high speed. However, they were able to produce 60% faster with the TC 19i, and clearer cut numbers were 50% lower than the first line. In light of these impressive results, Acarsoy is now considering modernizing its other machines too.

At present, the quality of T-shirt products in Knitting fair is uneven, and the homogeneity is serious. It only pays attention to style design and neglects the functions of conformal comfort, breathability and sweat, and environmental protection. In the context of consumption upgrades, "black technology fabrics" have become the core direction of consumption upgrades for T-shirts. The combination of comfort, environmental protection and personalized design is also a new demand for consumers in the Z era.

DuPont Sorona and Sateri’s EcoCosy have together developed a new fabric called StretchCosy, a blend of Sorona, a partially plant-based fibre, and Sateri’s ‘ultra-comfortable and near weightless’ EcoCosy fibres to achieve a soft material that is highly stretchable, shape-retaining and, most importantly, sustainably sourced, the companies report.

StretchCosy™ is an environmentally friendly fabric that has been used in the field of woven fabrics and knitted fabrics and has won unanimous praise from consumers and brands. Especially in the application of summer T-shirt knitted fabrics, YouZan™ fabric cooperates with the well-known KOL Shui Bingyue to launch T-shirts with a monthly sales of 1.5w+; and cooperates with domestic independent designer women's clothing brand IN AND ON to launch women's solid color T-shirts. Deliver high-tech fabric performance and high-quality lifestyle. The elasticity and shape-preserving, natural skin-friendly, dry and breathable, environmentally sustainable and other characteristics of U-Stretch™ fabrics give more possibilities for the upgrading and development of T-shirt categories.

Comfortable elasticity, excellent shape retention: The traditional cellulose fiber and spandex fabric has weak durability in terms of wearing experience, and it is easy to deform and lose shape after repeated washing. Experiments show that StretchCosy™ fabrics can still maintain a good appearance and not easily deform after repeated washing.

The natural spring-like molecular structure of SORONA® elastic fiber in the fabric, coupled with the optimization of different spinning processes, the fiber strength of the SORONA® elastic fiber is higher than that of ordinary cellulose fibers, resulting in the excellent shape retention of the fabric. And the cloth surface is smooth and clean, at the same time it has excellent wrinkle recovery performance, no matter in the warp or weft direction, it has better recovery.

Skin-friendly feel, dry and breathable: Whether it's woven or knitted fabrics, U-Stretch™ fabric always brings a soft and natural feel. The combination of the two materials gives the fabric an excellent touch and improves fabric comfort. The natural moisture absorption of Eucocel® fiber, combined with the moisture conductivity of SORONA® fiber, creates a significant moisture wicking effect for the fabric, giving consumers a natural touch like a "second skin".

Sustainable environmental benefits: The importance of sustainable fashion practices is beyond words. DuPont™ SORONA® fiber is derived from plant raw materials that can be grown repeatedly every year. The core PDO is derived from plant starch glucose, not petroleum. Compared with nylon, the process of SORONA® fiber reduces the consumption of petroleum resources by 37%, saves 30% of energy use, and reduces 63% of greenhouse gas emissions. EcoCosy® fiber comes from internationally certified natural planted forests, responsible closed-loop production, leading recognition by the Higg Index, 100% bio-based, biodegradable, and recyclable.

StretchCosy combines the mechanical stretch of Sorona stretch fibres, which is said to give it excellent stretch and long-lasting, consistent recovery, with the soft, cotton-like breathability and smooth silk-like texture of EcoCosy for an unparalleled fabric that is high-performing and well-suited for fashion and sportswear.

Created in 2019, StretchCosy is a fabric breakthrough that made it possible for natural plant-based fibres to be more extensively used in various applications, for example t-shirts, shirting, bottoms, jackets, dresses, hoodies and underwear. “Previously, cellulosic fibres were rarely found in sportswear, due to concerns such as pilling, the partners say. “The combination of Sorona and EcoCosy in StretchCosy has eliminated this concern, hinting at the future of activewear where performance combined with sustainability will be the norm.”

Tom Liu, Sateri’s Vice President for Commercial, commented: “StretchCosy marries the best of Sorona and EcoCosy. In addition to their complementary properties, both fibres are derived from plant-based materials. Sorona is partially made using renewable plant-based ingredients, while EcoCosy fibres come from certified and sustainable wood sources. The end product, StretchCosy fabric, is not only a natural and comfortable fabric, but also sustainable.”

“The global sports apparel market is forecasted to reach around USD 208 billion in 20251. Combined with the rise of the athleisure fashion movement and an increase of stay-at-home workouts due to the COVID-19 pandemic, demand for clothing that is high performing yet comfortable is expected to continue growing. StretchCosy embodies these characteristics, a win-win situation for sustainable clothing,” the fibre brands added.

Renee Henze, Sorona Global Marketing Director, said: “It is encouraging to see members of the same industry come together to collaborate for the better good. Our partnership with Sateri in creating StretchCosy combines innovation from both fibre offerings into a superior product that we believe not only will exceed consumer expectations but is kinder to the environment.”

StretchCosy has apparently been well-received by fabric manufacturers and various brands, including Shui Bing Yue, In & On, and famous women’s fashion brand Eifini. Such feedback has prompted both companies to formalise and deepen the strategic partnership with the introduction of StretchCosy, and confidently look forward to a greater success across segments in the near future.

As far as Knitting fair knows, Naia Renew fibre is said to be traceable with certified biodegradability that captures the value of hard-to-recycle materials that would otherwise be destined for landfill.

Eastman, the producer of sustainably sourced Naiaä cellulosic fibre, has introduced its new Naia Renew portfolio, sourced from 60% wood pulp and 40% recycled waste plastics. Naia Renew cellulosic fibre is said to be traceable with certified biodegradability that captures the value of hard-to-recycle materials that would otherwise be destined for landfills. It can be produced at scale to deliver sustainability without compromise to the fashion world, Eastman reports.

Naia™ is sourced from sustainably managed pine and eucalyptus forests and plantations. Eastman's entire forestry supply chain adopts FSC® Forest Stewardship Council® procurement standards, including controlled wood procurement procedures.Eastman and its wood pulp suppliers hold FSC® Forest Stewardship Council® (C140711) and/or PEFC™ Forest Certification System Recognition Scheme™ Chain of Custody certification. In addition, Eastman also cooperates with the non-profit environmental protection organization Canopy to show long-term support for sustainable forest management.

Naia™ cellulose fiber adopts a safe closed-loop production process, and the solvent used in the process is recycled into the system and recycled. Reduce the environmental impact by optimizing the production process. From trees to fibers, Naia™ has only a very low environmental footprint, and the third-party certified life cycle assessment results meet the ISO 14044 standard. Naia™ is biodegradable in freshwater and soil environments, and compostable in industrial environments, and has obtained the "OK biodegradable" and "OK compostable" certifications awarded by TÜV AUSTRIA. Recently, Naia™ staple fiber obtained the “OK compostable” certification for the home environment.

“Naia Renew enables a circular economy for the fashion industry and helps brands meet their eco-conscious goals,” said Ruth Farrell, global marketing director of textiles for Eastman. “We’re transforming what a fabric can be and do to meet the sustainability demands of our customers and to create a world where brands and consumers can be in fashion without compromising on quality and performance.”

Available as both a filament yarn and a staple fibre, Naia Renew offers clear advantages over other materials, Eastman adds. Naia Renew filament features a silky hand, rich lustre and fluid drape and is used to create fashionable womenswear garments, while Naia Renew staple fibre is inherently soft and quick drying, with reduced pilling properties, making it ideal for everyday casual wear.

According to Eastman, fully circular, Naia Renew is produced with a low carbon footprint in a closed-loop process where solvents are safely recycled back into the system for reuse. The fibre is made from wood pulp sourced from certified forests, and the recycled plastics feedstock is generated via Eastman’s patented carbon renewal technology (CRT). CRT is an integrated, molecular recycling technology that breaks down waste plastics, such as post- consumer carpet fibre and plastic packaging materials into basic molecular building blocks for the manufacture of new products including fibres. Eastman says it is a truly circular solution creating value from waste.

Naia is actively collaborating across the value chain for Naiaä Renew and will have announcements regarding brand partnerships soon.

“Our vision is to make sustainable fashion accessible for everyone,” Farrell added. “We all need to play our parts to help fix the future and work together to protect our planet’s precious resources for the next generations. With Naia Renew, you can take an active role in conserving resources and fostering innovation, while demonstrating a passion for sustainability that resonates with consumers worldwide.”
