Beschreibung
Zusammenfassung:	The present invention discloses high moisture absorption and anti-yellowing polyamide fibers and a production method thereof, wherein the fibers contain a high moisture absorption compound polyvinylpyrrolidone with a dispersion diameter of less than 2 mum, the terminal of the fiber-forming polymer polyamide molecule chain of the fibers contains 1.010-3.010 mol/g of the terminal amino group and a nitrogen-containing terminal structure, the nitrogen-containing terminal structure is formed by carrying out a chemical reaction of C2-C20 carboxylic acid and the terminal amino group of the polyamide polymer molecule chain, and the polyamide polymer is copolymerized caprolactam or copolymerized adipic acid hexane diamine obtained by adopting an aromatic dicarboxylic acid as a copolymerized monomer. The high moisture absorption and anti-yellowing polyamide fibers have characteristics of effectively yellowing inhibiting, high moisture absorption and good fiber whiteness.
