Taking waste sweaters as the starting point, research on its recycling technology. First of all, through the optimization technology of yarn development, the physical method is used to actively explore and improve the performance of waste spinning yarn to meet the standard of use. Third, the waste textiles that cannot be recycled by physical methods should be treated by chemical methods to maximize the utilization rate of textiles. Dissolve wool, separate acrylic fiber, and extract keratin protein from wool with wool and acrylic blended raw materials, and obtain pure keratin membrane with certain mechanical properties by dissolving and dialysis method. It is used as functional membrane material, and the dialysate can be used as daily chemical products. Additives, etc.; surplus acrylic fiber is regenerated by wet spinning, and reasonable organic solvents and processes are explored in the entire recycling process to reduce secondary pollution during the recycling process, and provide a reference for the development of textile green recycling.

      Through the training of Daiso project, the small partners of the research group have indeed experienced many professional skills, and during market research, the whole group visited many black-heart cotton processing dens in many places. On the one hand, everyone was concerned about the messy and poor working conditions. Worry, in addition, for low-end recycled fiber, it can only be used to make low-value products such as building insulation materials or black cotton, flood control materials, and paving materials.

    Now Han Du and Zhang Zhuanhui are already working as technians, Lang Qian is doing research and development in the Ministry of Public Security in Beijing; Zhang Guicheng received a master’s degree from the Technical University of neider Rhine in Germany, and is developing higher-level studies. During the period I went to Germany Visited Guicheng and met Professor Macus Weber and Professor Busgen.
