Abstract
This invention provides a method for the treatment of cellulose containing fabrics with inorganic phosphorylating agents to obtain durable press or smooth drying fabrics. The method involves treating the cellulose-containing material with 8-16% of an inorganic phosphate, 16-32% of urea, 0.5-2.0% of a catronically emulsified polyethylene fabric softener, 0-6% of a polyacrylate or suitable polymer emulsion (glass transition temperature: -20.degree. to -43.degree. C.), and then drying the fabric at 60.degree.-100.degree. C. for 3-7 minutes. The fabric is crosslinked to obtain durable press or smooth drying properties by curing at 160.degree.-170.degree. C. for 3-9 minutes.
