ABSTRACT:
A non-formaldehyde polymerization-crosslinking treatment for cotton or other cellulose-containing fabrics resulting in a fabric with good durable press, wrinkle recovery, and other mechanical properties. Unsaturated monomers having two or more carboxyl groups are used in a polymerization-crosslinking treatment at a pH below about 3. The preferred system uses maleic acid and itaconic acid comonomers, potassium persulfate as a free radical initiator, and sodium hypophosphite as an esterification catalyst. A high quality durable press cotton fabric may be produced which does not release formaldehyde during processing, storage, or consumer use.
