    摘要: A highly hygroscopic polyamide fiber formed from a polyamide compound containing a polyvinylpyrrolidone (in an amount of 3-15 wt %) which is synthesized in isopropyl alcohol as a solvent, contains pyrrolidone in an amount less than 0.1 wt %, and has a K-value of 20-70. This fiber contains pyrrolidone in an amount less than 0.1 wt % of the amount of polyvinylpyrrolidone. This fiber is characterized by a yellowness index lower than 10 before dyeing, a large difference between the maximum moisture absorptivity and the standard moisture absorptivity, and a low content of water-soluble components that are subject to leaching.
