ABSTRACT:
Cotton, or other fabric containing cellulose, is treated with acrylamide and a chemical initiator that promotes reaction of acrylamide with cellulose. The fabric, with bound acrylamide, is then treated with glyoxal and an acidic, metal salt catalyst to produce a fabric containing crosslinked cellulose. Thus, the fabric is given wrinkle resistance and durable-press properties by the treatment without using formaldehyde, free or combined, that could be released during treatment or from the treated fabric.
