ABSTRACT:
The use of 4,4'-azobis(4-cyanovaleric acid) and its salts as water-soluble free radical initiators, and simultaneously or alternatively the addition of catalytic amounts of tetrakis(hydroxymethyl)phosphonium sulfate as a polymerization accelerator, in the sequential polymerization and acid-catalyzed grafting of N-methylolacrylamide on cotton textiles from a single treating bath in a padding and two-stage heat curing operation, is disclosed. The cotton textiles as treated are free from discoloration and excessive tendering produced by peroxide-type initiators, and these textiles exhibit increased smooth drying performance, abrasion resistance and strength relative to textiles treated conventionally with dimethyloldihydroxyethyleneurea to comparable wrinkle recovery angles.
