ABSTRACT:
Zwitterions are employed as catalysts in a chemical finishing process to treat cellulosic textiles with crosslinking agents and produce easy-care properties in the finished materials. The process comprises treatment of the textile material, such as cotton fabric, by impregnating it with a solution containing a cellulose-crosslinking agent and, as catalyst a zwitterion, alone or in combination with a magnesium salt, drying and curing the fabric. Said finished fabrics are characterized by an unusual combination of useful, desirable properties--smooth-drying appearance, wrinkle resistance, serviceable strength, and inoffensive formaldehyde release.
