ABSTRACT:
The acetals, 2,3-dihydroxy-1,1,4,4-tetramethoxybutane, 3,4-dihydroxy-2,5-dimethoxytetrahydrofuran, and glyceraldehyde dimethylacetal, when applied to cotton fabric by conventional pad-dry-cure procedures using special combined acid catalysts, were found to crosslink cellulose hydroxy groups at a very rapid rate (e.g., 20 seconds at 160.degree. C.), thereby imparting improved wrinkle recovery in the range of that required for durable press finishing. Cotton fabrics treated with these acetals have the advantage of no formaldehyde release.
