PURPOSE: To obtain fabric rich in wearing comfortableness by imparting synthetic fiber fabric with an aqueous solution containing a polymerization initiator and a monomer mixture of a specific group-contg. vinyl compound and vinylcarboxylic acid at a specified weight ratio followed by steaming and then hygroscopicity-developing treatment.
CONSTITUTION: Synthetic fiber fabric is imparted with an aqueous solution containing (A) a monomer mixture of (1) an N-alkylolamide group-contg. vinyl compound (pref. N-methylolacrylamide) and (2) a vinylcarboxylic acid [e.g. (meth)acrylic acid] at the weight ratio (1:3)-(4:1) and (B) a polymerization initiator followed by steaming (and pref., in addition, high-frequency heating) and then pref. substituting cation such as ammonium ion for the hydrogen ion of the carboxyl group in the resulting copolymer to make hygroscopicity-developing treatment, thus obtaining the objective fabric rich in wearing comfortableness, which is suitable for sportswears or underwears.
