In summary, the present application uses PLA fiber to replace conventional polyester fiber used in traditional cotton-polyester denim to create a new type of environmentally friendly and comfortable denim fabric. PLA fiber is a new type of biodegradable material derived from renewable plant resources. It uses corn, wheat and other starch-containing agricultural products as raw materials. It saves more water and pesticides than cotton fiber in the production process, and has good biodegradability. It is a recognized environmentally friendly material. PLA has superior performance, good elasticity, drape, good hand feel, good curling and curling stability, natural antibacterial, quick drying, excellent moisture removal ability, and can be made into a fabric with moisture absorption and quick drying function when combined with cotton fiber.
