Application
It can be used as acid dye and dyeing aid;
Adjust the pH value of the dye solution.
Help control the pH of the dye solution to create a suitable chemical environment for the combination of dye and fiber.
It is used to vat dyes and promote dyeing reactions. It helps to enhance the adhesion stability of the dye on the fiber, so as to improve the fastness of washing resistance and friction resistance after dyeing.
Promote fiber bulking to make the structure of the fiber become loose, which is conducive to the penetration and diffusion of dyes, thereby improving the uniformity and depth of dyeing.
