ABSTRACT:
A process for producing a polymeric-type film in the surface of cellulosic fibers is disclosed. Cellulosic fibers are irradiated in the colored area of a radiofrequency plasma of ammonia for a period of about 10 minutes to 2 hours in a reactor designed to admit ammonia between electrodes at a rate such that all of the ammonia molecules have been activated to plasma. A polymer coating is formed in the surface of the cellulosic fibers that is alkali resistant, water-repellent and improves the wrinkle recovery of the fabrics.
