Anti-wrinkle and no shrinkage, sensitive to temperature changesTextiles with memory functions are being developed all over the world, said Ye Xiaoyun, associate professor of the Department of Textiles and Clothing at the Hong Kong Polytechnic University: "Japanese companies have invented a polyurethane-based polymer Diaplex film with shape memory function to make sports clothing, which can sense the temperature of the human body or the environment.
Change, the molecular chains in the film are arranged differently, so as to keep warm in winter and breathable and perspiration in summer
