DuPont Biomaterials has taken the development of the Sorona fibres, created by the company from renewable plant sources instead of traditional petrochemical ingredients, to the next level with variants designed for trousers and jeans, seamless apparel and swimwear. The new development took place in order to provide the apparel designers with sustainable, high-performance fibres and fabric options for their collections.
The sorona fibres are exceptionally soft; possess comfort stretch and recovery and also have chlorine and UV resistance. The production of the fibre uses 30% less energy and cuts the CO2 emissions by 63% compared to synthetic fibres like nylon. The apparel made from the fibre can be easily blended with a variety of cellulosic fibres like cotton, wool or rayon to create fabrics with excellent recovery and a natural touch. Said to be ideal for seamless underwear, sports T’s and leisure wear, draw textured yarn (DTY) with Sorona also has a cotton-soft feel; while air jet textured yarn (ATY) is colourfast after several washes and exposure to UV. The filament fibre used for the swimwear combines soft hand with UV and chlorine-resistant performance that stands up to colour fading after frequent uses and has a built-in wrinkle release performance.
