The tie-dyeing process is divided into two parts: tie-dyeing and dyeing. It uses yarn, thread, rope and other tools to bind, sew, tie, tie, clip, etc. to the fabric before dyeing. Its purpose is to prevent dyeing of the knotted part of the fabric, so that the knotted part maintains the original color, and the untieed part is evenly dyed. As a result, uneven shades and rich layers of color halos and wrinkles are formed. The tighter and firmer the fabric is tied, the better the anti-dyeing effect.
