Application
It removes wax, pectins and other impurities from natural fibers Such as cotton and linen, so that the fibers become purer and looser, which is conducive to subsequent dyeing and printing.
It increases the gloss, strength and adsorption capacity of cotton fabric and improves the dyeing property and appearance quality of fabric.
It provides suitable pH conditions for dyeing and color fixing to ensure the dyeing effect. It helps some dyes to fully dissolve and disperse in the dye solution to ensure the uniformity of dyeing.
In the post-dyeing treatment, it helps to remove the unfixed dye from the surface of the fabric and improves the dyeing fastness and color brightness.
