This liquid can fix color.
Acidic dyes react with the amino groups in basic dyes to form amide bonds. Amide bonds are relatively stable chemical bonds that allow dyes to adhere firmly to fabrics. Therefore, basic dyes can be fixed with acidic liquids.
Acid fixing agent is a chemical substance widely used in the textile industry. It can fix dyes under acidic conditions, thereby improving the color and stability of textiles. When using acidic fixatives, you need to pay attention to the correct ratio and addition amount. Generally speaking, the amount and concentration of acid fixing agent should be determined according to the characteristics of specific fibers and dyes.
