TY2-20 Perspiration fastness enhancer

Reactive dyes are a popular choice for cotton fabrics due to their excellent wash fastness and level-dyeing properties. However, a significant challenge arises with certain colors like turquoise blue, pink, and light grays: poor light-perspiration composite fastness.

When cotton garments dyed with these reactive colors come into contact with human sweat and are then exposed to sunlight, they tend to fade. This is caused by a photochemical oxidation reaction triggered by amino acids in sweat, leading to customer complaints and failed quality tests.
