1.DW50 is a special cationic agent for the weight reduction of polyester.
2.DW50 is absorbed on the surface of polyester. Then it accelerates hydrolysis so that
improves the efficiency of weight reduction of alkali.
3.DW50 does not induce any deterioration of polyester fiber.
4.DW50 is so excellent in water solubility that never induces the deterioration both of
brightness and dyeing effect in the dyeing process
