PURPOSE: To impart a cellulose-based textile fabric or sewn product with easy- care properties, permanent-press effect and wrinkleproofness without leaving any unreacted crosslinking agent such as free formaldehyde therein. CONSTITUTION: A cellulose-based textile fabric comprising 100% cotton is scoured, bleached and mercerized, and then impregnated with a treatment liquid containing a crosslinking agent reactive with the cellulose fibers such as an epoxy resin, and if necessary, made into a sewn product. Subsequently, a catalyst such as hydrogen chloride in the form of vapor or mist is adsorbed to the resultant fabric or sewn product followed by conducting a heat treatment to effect crosslinking of the cellulose fibers without leaving any unreacted crosslinking agent therein. |
