To exclude defects essential to a spinning and weaving textile material such as a high affinity for oils, problems about fouling during washing or coiling around with static electricity and an unpleasant feeling for a wearer with a hydrophilic finishing agent.
This improved type spun and woven fiber having a hydrophilic finishing agent is produced by a method comprising steps for applying an aqueous solution containing an anhydride-based graft copolymer to a fiber web and drying the fiber web at a temperature sufficient to cure the anhydride-based graft copolymer. The anhydride-based graft copolymer is a reactional product of an ethylenically unsaturated monomer with an anhydride monomer selected from maleic anhydride and itaconic anhydride, a polyglycol having a monofunctional value and hydroxyl or amine terminal groups or a polyglycol having >5,000 weight-average molecular weight, at least one terminal hydroxyl group and a polyfunctional value and a radical initiator.
