Abstract

Textile substrates are printed in a variety of styles, including direct, discharge, resist, and so on. The dye of a ground-dyed fabric is released from the desired design or pattern in the discharge style of printing. This discharge might result in either a white or colorful pattern. Because of its emphasis on patterns with diverse colors on a dark backdrop, discharge printing is becoming increasingly popular in both local and foreign markets. It was discovered that a design might be bleached off or discharged from an already piece painted material using chemical techniques. Printers may create elaborate and precise patterns using this discharge method. The chemicals used to discharge the dyes are classified as either oxidative or reductive agents.
