[0002] When jeans are produced, it is necessary to desizing the black cloth with a layer of indigo coloring dye on the surface. Indigo coloring dye is used to facilitate processing, transportation and sewing in jeans. The removal of the indigo coloring dye on the skin, followed by rinsing and sanding, so that the jeans produced have an old feeling, and the fabric is soft and comfortable to wear. However, the existing treatment processes are directly in the formed jeans. Soak in (potassium permanganate, oxalic acid, etc.), and finally polish it with pumice stone. Although the processed jeans have a sense of oldness and softness, the color or color is not beautiful, and because the formed jeans are sewn with needles and threads, they will not be cleaned in potion. During the soaking process, there will be shrinkage, and the denim pants after coming out will have fine wrinkles at the junction, which cannot meet the pursuit of high quality
