The so-called garment waste refers to the products processed by domestic garment manufacturers according to foreign materials, samples or foreign samples and domestic materials, including the defective products that can't be seen from the fabric, specifications and colors, the redundant or saved fabrics, the "export-to-domestic" garments returned from abroad without defective products, and some garments rejected after inspection. China garment manufacturing enterprises undertake more than half of the global garment processing tasks. However, foreign brands usually adopt the method of "processing with supplied materials" when placing orders. In order to ensure the production of enough qualified products, of course, the ration of imported materials will definitely exceed the order requirements. However, after the manufacturer delivers the goods according to the order, there will always be some surplus, and this part of the goods will become "tail goods".
