China Garment Industry Technological Progress and Contribution Awards 2023
China Garment Industry Technological Progress and Contribution Awards recognise industry enterprises for their technological innovation practices and outstanding technological achievements that have valuable applications for promotion.
Green Machine is a polyester and cellulose recycling system by hydrothermal treatment and dissolution treatment on cotton and polyester blends. Through decomposing cotton into cellulose powders, it enables the separation of the polyester fibres from the blends. The quality of the polyester fibres is maintained, permitting fibre-to-fibre recycling. Recycled cotton cellulosic powder will be used in re-spinning and agriculture. Based on the research result of phase I development, this project aims to develop the Green Machine into a complete treatment process and an industrial set-up.
Through separation of the blended textile, Green Machine recovers PET fibre for re-spinning, while converts cotton fibre into cellulosic powder for a number of uses, including the re-producing of cellulose composite fibre, cellulosic superabsorbent polymer for cotton farming (Absorboost), and PFC-free function durable water-repellent (DWR) surface finish, hence fulfilling the goal of “end-to-end recycling” where post-consumer textiles are recovered as the raw materials of the production cycle.
