reactive dye friction fastness improver for dark fabric



 The active, vulcanized, direct and indigo dyes are particularly low when they are dyed thick and dark on cellulose fibers, especially in the case of large black, red and green blue, which are often lower than grade 1, while the textile products exported to Europe and the United States require more than grade 3 to improve the stability of the products to salt and alkali and to reduce the shortage of the structure of the products themselves. Therefore, the environmentally friendly wet rubbing fastness agent has been specially developed.
