PURPOSE:To obtain the subject textile fabric excellent in W&W disposition and good in touch feeling with its mechanical strength retained, by imparting a textile fabric containing cellulose-based fibers with a resin followed by conducting a vapor treatment with formaldehyde gas. CONSTITUTION:A textile fabric containing cellulose-based fibers is imparted with about 2-15wt.% of a resin reactive with cotton fibers followed by drying and then conducting a vapor treatment with formaldehyde gas at 100-160 deg.C for 20-120min (esp. 140-155 deg.C for 30-70min) to obtain the objective textile fabric excellent in crease resistance and W&W disposition and good in touch feeling with its mechanical strength, i.e., tear strength and tensile strength, retained. The resin is e.g. glyoxal-based polymer, dimethylol dihydroxyethyleneurea polymer, dimethylolurone polymer, water-soluble urethane polymer having blocked isocyanate group capable of regenerating two or more isocyanate groups. Addition of a polyhydric alcohol (e.g. glycerin, ethylene glycol) to the formaldehyde gas further improve the crease resistance of this textile fabric. |
