ANTIMICROBIAL POLYAMIDE BLEND FIBER WITH HETEROGENEOUS DENIER AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a blend yarn with heterogeneous deniers comprising an antimicrobial polyamide fiber capable of expressing good antimicrobial activities, hardly expressing a color change (coloring) and reducing the antimicrobial activities even after an alkaline processing and expressing dry feeling, soft feeling and bulky feeling in its woven and knit fabrics and provide its production. SOLUTION: This antimicrobial polyamide blend fiber with heterogeneous deniers is a blend yarn comprising a thick denier yarn having >=2.5 de monofilament denier and a thin yarn having <=1.5 de monofilament denier and the rate of the thick yarn in the blend yarn is 20-95 wt.% and that of the thin yarn is 5-80 wt.%. The thick and thin yarns comprise a polyamide resin containing 0.1-5.0 wt.% of fine particles of zinc oxide in which the surfaces are coated with a coupling agent and having <=2.0 color difference of coloring after an alkaline treatment.
