Abstract
Acetals of glyceraldehyde, when applied to cotton fabric by conventional pad-dry-cure procedures using special combined acid catalysts, were found to crosslink the cellulose hydroxyl groups at a very rapid rate (e.g., 10 seconds at 170.degree. C.), thereby imparting improved wrinkle recovery. In particular, the aldehydes studied were the diethyl and dimethyl acetals of glyceraldehyde. The best results were obtained with glyceraldehyde dimethyl acetal.
