Low temperature soaping agent TY-1128 is a low-temperature anti staining soaping agent launched by our company after dyeing with reactive dyes. It can significantly reduce the frequency of water washing and soap washing, save water and energy, and shorten the process flow; It has strong dye affinity and is used to remove hydrolysis products of reactive dyes and unfixed dyes, keeping the hydrolysis products in the dye bath to prevent re staining of fabrics. Reducing the soap washing temperature for blended fabrics can also achieve good results, improving the soap washing fastness and sweat stain fastness of dyed fabrics.
