Toray Industries in Japan has announced the development of a polyester nylon composite fiber with a recycled material content of at least 93% by weight, achieving technological breakthroughs in high recycled content composite yarn. This development solves some of the technical challenges faced when combining recycled polymers for high-performance textile yarns. This achievement will form the foundation of the new fabric series Artirosa CX, which aims to be applied to high-end outerwear, urban outdoor clothing, and casual wear. It is planned to be commercially introduced in the autumn and winter of 2027.
The polyester and nylon components of the new fiber are made of recycled materials, based on Dongli& +The technology developed by the Regenerated Fiber Program. Producing composite fibers with high regeneration content faces special challenges as different polymers must be processed together while maintaining consistency in yarn quality and performance. Dongli stated that these difficulties have been resolved through advances in polymer design and composite spinning technology.
The regeneration content data applies to raw yarn rather than finished products
The company emphasizes that the number 93% specifically refers to raw yarn, not finished fabrics or clothing – the regeneration content of the latter will vary depending on structural design and the addition of other materials.
. Dongli is currently evaluating the applicability of this technology for large-scale production, while continuing to research methods to increase the regeneration content in composite fibers. The Artirosa CX series combines composite yarns with fabric design, weaving, knitting, dyeing, and finishing techniques from mature textile manufacturing regions in Japan. The obtained fabric has a dense and fine textured surface and a crisp feel, and the post finishing process can endow it with additional properties such as waterproof, long-lasting water repellent, and windproof. Dongli stated that the fabric can also achieve water repellency without intentionally adding perfluorinated and polyfluoroalkyl substances (PFAS) in the water repellent finishing agent.
Targeting applications that emphasize both appearance and performance
The company positions this series in application areas where appearance, drape, texture, and technical performance are equally important, especially in high-end outerwear.
. Further development will include combining with natural fibers, replacing nylon blends, and other finishing techniques. Dongli’s target Artirosa CX has a first-year sales volume of 200000 meters.
Significance for the polymer additive industry
From the perspective of the fiber and fabric column, this development involves spinning and fiber processing, functional and high-performance fibers, and non-woven fabric related technological paths.
. The co processing of different polymers in composite spinning requires higher requirements for thermal stability and processing window, and antioxidants have the potential to prevent degradation of polyester and nylon during melt spinning. At the same time, the demand for weather resistance and stability for high-end outerwear, including the durability of post-treatment properties such as water repellent and windproof, also means that weather resistance and stability additives need to be compatible with recycled raw material systems in fiber level and fabric level formulations. Dongli explicitly states that 93% only applies to raw yarn, and the finished fabric may change due to the addition of structure and other materials, indicating that the formulation design of additives needs to consider the balance between recycled content and final performance. This technology is still in the stage of large-scale production evaluation, and its commercial progress will provide new application scenarios for fiber antioxidants and weather stability solutions.
