HOLPOSON® Color Keep-Sweat
Color Keep-Sweat is a color fastness enhancer developed to remove the unstable disperse dyes on polyester or polyester/Spandex blended fabrics.
When polyester/Spandex knitted/woven fabric is dyed with disperse dyes, the Spandex elastic yarn will absorb a lot of dyes and cause serious staining. The disperse dyes on Spandex are usually difficult to remove, and they will remain in the fibers after reduction cleaning, which will lead to the decrease of dyeing fastness and other problems. When Color Keep-Sweat is added in the conventional reduction cleaning, the unstable disperse dyes on the polyester and Spandex can be removed effectively. Eventually, dyed materials with good fastness can be obtained.
