Sinosol WH reactive dyes are new type wool reactive dyes containing composite reactive groups. Because of their optimized chemical structure, they have high reactivity, good stability to acid, low hydrolyzing in alkaline medium, very good migration, levelness and reproducibility. With the pH of dyeing bath at isoelectric point and the temperature at 80-90 ℃ , they can reduce the damage to wool and keep the hand feeling of wool fiber. Their high wet fastness can meet or even exceed the IWS standards. They have the following advantages: brilliant shades, high fixation,low hydrolyzation, high light and wet fastness. They are widely used in women’s fancy knitted outwear,army service dress, worsted merino, high quality wool yarn etc, and also used in shrink-proof treated wool roducts matching the “Superwash Wool” fastness requirements.
