Abstract
Provided is a composite fiber comprising an ethylene-vinyl alcohol copolymer and a thermoplastic polymer. The composite fiber is acetalized with a dialdehyde such that the ethylene-vinyl alcohol copolymer has a melting point in a specified range, whereby the composite fiber does not cause serious stickings between the filaments when dyed, sewn or ironed and is excellent in hydrophilic property, resistance to soiling, antistatic property and the like. The composite fiber is thus very suitable for clothing use.
