ABSTRACT:
The instant invention deals with the alteration of solid synthetic polymers to improve the overall functional performance of the polymers. The invention also deals with a fast, clean, efficient, inexpensive method of altering the surface of textiles. The method comprises contacting a textile with a swelling agent and a base and heating to alter the textile, and then acidifying the treating bath and contacting the textile with an active substance, such as a hydrophilic polymer, to further alter the textile.
