What is the principle of burnt-out printing?

General burn-out printing process is carried out on polyester-cotton blended fabrics. Corrosion of cotton fibers produces a transparent mesh pattern, which forms a contrasting print, embossed three-dimensional, and elegant print fabric.

Cotton, hemp, rayon, viscose fiber and other plant fibers have alkali resistance, but the acid resistance is poor; wool, silk and other animal fibers have acid resistance, but the alkali resistance is poor; polyester and other synthetic fibers are both resistant Alkaline, acid resistance. By utilizing these chemical properties, various blended fabrics or cross-fabric and core-spun yarn fabrics composed of these fibers are subjected to corrosion processing to form a burnt-print fabric.
