Teijin Frontier: hybrid fiber made with plant-derived and recycled materials
An eco-friendly plant-derived polymer with a chemically recycled polyester polymer, each featuring different heat-shrinkage characteristics to enable the formation of coiled crimp yarn has been introduced by the fiber-product converting company Teijin Frontier Co., Ltd., Tokyo/Japan.
The new Solotex Eco-Hybrid high-stretch side-by-side (S/S) conjugated fiber represents a new line in Teijin Frontier’s polytrimethylene terephthalate (PTT) fiber Solotex family. Solotex Eco-Hybrid filament yarns feature extra stretchability achieved with new technology for conjugating PTT polymer and polyethylene terephthalate (PET) polymer made with chemically recycled raw material, which are then processed to create a crimp structure. Crimp structure is equivalent to that of petroleum-derived raw materials, and dyeability is achieved with optimized yarn-making conditions.
Solotex Eco-Hybrid has the same features as conventional S/S conjugated fiber made with petroleum-derived raw materials. PTT polymer is partly made with plant-derived raw materials and PET polymer is made with chemical recycled raw materials such as used PET fibers. A wide range of fineness, from 33-330 dtex, and filament yarn processing is possible. Yarns made with the new fiber are stretchable and dyeable, equivalent to those of petroleum-derived materials, and soft texture.

Oerlikon Barmag: 5 new lines for capacity expansion in China
Production capacities at the industrial yarn manufacturer Zhejiang Kingsway High-Tech Fiber Co., Ltd., Dingqiao, Haining/China, are being expanded by a further 40,000 tons/year with 5 lines from Oerlikon Barmag, Chemnitz/Germany, a subsidiary of the Oerlikon Manmade Fibers segment of Oerlikon Management AG, Pfäffikon/Switzerland.
Kingsway is already successfully manufacturing special high-quality yarns, exclusively deploying Oerlikon Barmag industrial yarn systems.
The 21 new spinning positions will be used to manufacture a broad product range: in addition to super-low-shrinkage (SLS) and high-tenacity (HT) yarn, the company also plans to produce automotive yarns for seat belts and airbags. The new systems are expected to commence manufacturing in 2021.
Lenzing: no dividend for 2019
The 76th Annual General Meeting (AGM) of the producer of cellulosic fibers, Lenzing AG, Lenzing/Austria, which was held in a virtual form via livestream due to the Covid-19 pandemic, resolved on June 18, 2020, not to distribute a dividend for the 2019 financial year. Effective from the end of the AGM, Felix Fremerey has retired from the Supervisory Board at his own request. Fremerey served on the Supervisory Board and various committees of Lenzing since 2018. The AGM elected Melody Harris-Jensbach, Chief Executive Officer of Jack Wolskin GmbH & Co.KGaA, Idstein/Germany, since November 2014, to serve on the Supervisory Board until the AGM resolving upon the 2023 financial year. In addition, the Supervisory Board mandates of Franz Gasselsberger and Patrick Prügger were extended. The subsequent constituent meeting of the Supervisory Board elected Peter Edelmann to serve as Chairman of the Supervisory Board, whereas Veit Sorger was elected to the position of Deputy Chairman.
Meridian: environmentally-friendly polyester yarns with additive technology
The yarn spinning and dyeing company Meridian Specialty Yarn Group, Inc. (MSYG), Valdese, NC/USA, is now offering polyester yarns processed with Ciclo technology, which allows polyester fibers to break down in landfills and the ocean at rates comparable to a natural fiber like wool. MSYG’s new yarns with Ciclo technology from Intrinsic Advanced Materials, LLC (IAM), Gastonia, NC/USA, can be treated with antimicrobials proven effective at reducing exposure to viral infections and have the same wearability, durability, functionality, and performance characteristics as polyester. At the same time, when thrown away, CiCLO yarns reduce the persistence of synthetic textile accumulation in landfills and synthetic fiber fragments in the ocean. The yarn is being processed in MSYG’s new manufacturing plant in Valdese, which opened in July 2019. The plant has been engineered to use a lot less water and power than comparable textile operations and generates much less effluent as a byproduct of the dyeing and drying process. The chemistry used to create Ciclo fibers is Eco Passport by Oeko-Tex certified. Extensive testing by reliable 3rd party laboratories over several years has proven that Ciclo technology fibers and yarns are effective at reducing synthetic fiber accumulation in landfills and microfiber pollution in the oceans.

Ascend: antimicrobial technology for textiles and nonwovens
A technology specially formulated to guard against the growth of mildew, fungi and other microbes to keep textiles and nonwoven fabrics fresher for longer has been introduced by the manufacturer of fiber technologies Ascend Performance Materials, Houston, TX/USA.
The technology Acteev Protect combines zinc ion technology with polyamide (PA)-based woven, nonwovens and knit fabrics. The active zinc ions are embedded into the polymer matrix, providing a long-lasting solution that does not wash away, unlike topical finishes or coatings. The PA fabrics are durable yet soft to the skin, and the nonwovens filtration media – available as nanofibers, meltblown and spunbond – efficiently keep out unwanted particles.
Additionally, the fabrics feature all the benefits of premium PA, which offer more comfort than polypropylene (PP) in single-use masks and allows knits and woven fabrics to be dyed, printed on and laundered. PA 66 resists abrasion and does not pill or shed microfibers. It has a soft hand and very good drape, and it can be dyed solid or bright colors.
Uniforms or activewear made with Acteev Protect will be durable and comfortable and can be designed to match current color trends. Because the zinc ions are embedded during the polymerization process, articles made with Acteev Protect stand up to 50 washes or more.
