Description

Technical field:

[0001] The invention relates to a method for extracting fibers from waste materials, in particular to a method for extracting cotton fibers from waste cotton elastic gauze. Background technique:

[0002] Cotton elastic gauze is spun into cotton elastic yarn by adding spandex elastic yarn in the warp process, and made into pure cotton elastic cloth. A certain amount of waste is inevitably produced in the production process. Since the waste contains about 3% spandex yarn, Therefore, this kind of waste cotton elastic gauze cannot be reused and processed, which will inevitably cause the waste cotton elastic gauze to be difficult to be effectively utilized. If the waste cotton elastic gauze is not handled properly, it will cause environmental pollution. Therefore, cotton fibers are extracted from waste cotton elastic gauze The technology can make textile waste be effectively recycled and comprehensively utilized to make up for the shortage of textile cotton f...
