1. What is discharge printing?

Discharge printing is a technique where a special paste is applied to dyed fabric to remove color in specific areas, creating patterns or designs. Instead of adding color, this process utilizes a chemical agent in the paste, which reacts with the dye to strip it away. This results in a design that has a contrasting base color without the need for additional dyes.

2. How does discharge printing work?

The process begins by dyeing the fabric in a specific color. Once the fabric is dried, a discharge printing paste, crafted by a specialized discharge printing paste manufacturer, is applied to the areas where the design is desired. The paste contains agents that react with the dye. After applying the paste, the fabric is often heat-treated to activate the chemical reaction, which removes the dye in those specific spots. This method allows for vibrant designs on a colored fabric background.
