Abstract
Acrylic fibers consisting of not more than 90 weight % of an acrylonitrile polymer and less than 10 weight % of a water-absorbing resin having a particular cross-linking density, particle diameter and degree of water-swellability, which are excellent in practical properties such as strength, elongation, color fastness, spinnability and water-absorption.
