Creaseproofing Cotton by in Situ Polymerization of N-Methylol Acrylamide (NMA),Acrylamide (AM),and Tetrakis (Hydroxymethyl) Phosphonium Chloride (THPC)

Abstract

Cotton fabric was impregnated with partially methylolated acrylamide, THPC, and zinc acetate, then cured and washed. In situ polymerization was encouraged. In a second step, fabric was padded with ceric ammonium nitrate catalyst, cured, and washed. A very favorable balance of crease recovery ¹/tensile strength was obtained when condi tioned crease recovery angles (W + F) were less than 260°. However, beyond this angle, strength loss increased rapidly with increasing crease recovery and approached that of conventional treatments. If the balance of crease recovery/tensile strength is optimized, there is not sufficient phosphorus in the fabric for flameproofing.
