Abstract
Cellulosic fiber-containing fabrics are made wrinkle resistant by a durable press process which comprises treating a cellulosic fiber-containing fabric with aqueous formaldehyde and a catalyst capable of catalyzing the cross-linking reaction between the formaldehyde and cellulose, heat-curing the treated cellulose fiber-containing fabric, preferably having a moisture content of more than 20% by weight, under conditions at which formaldehyde reacts with cellulose in the presence of the catalyst without a substantial loss of formaldehyde before the reaction of the formaldehyde with cellulose to improve the wrinkle resistance of the fabric.
