Polymethylol Polycarbamates in Durable Press

Abstract
The cross-linking effectiveness of polymethylol polycarbamates for cotton fabrics has been studied by various application techniques. Poly(N,N-dimethylol) and poly (N-methyl, N-methylol) polycarbamates were compared under reaction conditions designed to give one-step and two-step cross-linking. The compounds react with cotton in high yields and impart excellent wash-wear properties without discoloration. Cotton samples cross-linked with poly(N,N-dimethylol) polycarbamates exhibit outstanding resistance to hydrolysis under acidic conditions, and their performance properties are compared to those of fabrics treated with N,N-dimethylol monocarbamates.
