Polyester is used as the core, which is coated or blended with cotton, acetic acid, viscose, hemp and other fibers to weave into a fabric. Then according to their different properties of acid stability, the acid slurry on the above-mentioned fabrics is charred and its non-acid resistant fibers (ie, cotton, acetic acid, viscose, hemp, etc.) retain their acid-resistant fiber polyester, which becomes translucent. The pattern, this process is called burn-in printing. In the printing of the printing paste, it can also be printed with white paint as the burn-out part of the edge, or acid-resistant disperse dyes added in the acid, so that the pattern portion of the polyester coloring; or the first printed coating as anti-printing paste, Then overcoating the yoghurt to produce an anti-printing effect on the printed part of the coating; or before the burn-out, the fabric will be first dyed and then burnt, etc.; the resulting flower shape will be colorful.
