| 摘要 |
Cellulosic materials such as cotton fabrics, preferably preimpregnated with an amide such as urea, are treated with formaldehyde vapor, formed into garments and cured in the presence of a catalyst to impart durable press and wrinkle recovery characteristics to such garments. The required curing catalyst may be furnished either by impregnating the fabrics with an aqueous solution of a weakly acid salt such as zinc chloride after exposure of the fabric to formaldehyde and before garment fabrication therefrom, or by furnishing a gaseous catalyst such as sulfur dioxide to the chamber in which the garments fabricated from the formaldehyde-treated fabric are cured.
