DuPont, Sateri tie-up to bring fabrics for fashion

DuPont Sorona and Sateri’s EcoCosy have together developed a new fabric called StretchCosy. The fabric uses 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.

StretchCosy combines the mechanical stretch of Sorona stretch fibres, which gives 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, e.g. t-shirts, shirting, bottoms, jackets, dresses, hoodies and underwear. Previously, cellulosic fibres were rarely found in sportswear, due to concerns such as pilling. 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, said, “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.”
