精梳棉羊绒紧密纺针织纱的纺制

摘要

探讨精梳棉羊绒紧密纺针织纱的工艺配置.针对羊绒纤维质量比电阻较高的特性,分析了影响其纺纱生产的各种因素,通过优化开清棉工序打手速度,减少有效纤维损伤,并采取防黏卷措施；梳棉工序优选梳理针布,纤维得到充分梳理,尽可能减少生条棉结和短绒含量；合理配置并条、粗纱、细纱工序的定量、速度、隔距以及紧密纺的集聚张力、负压等工艺参数,最终顺利纺制出精梳棉羊绒紧密纺针织纱,其成纱质量可满足高档针织纱的使用要求.%Processing of spinning combed cotton cashmere compact knitting yarn was discussed. According to property of higher fiber mass specific resistance, factors of effecting spinning production were analyzed. Beater speeds were optimized in opening and picking process to reduce effective fiber injury, anti-sticky measures were adopted. In carding process, card clothing was optimized to ensure fiber carding, neps and short fiber content of card sliver were reduced as much as possible. Processing parameter was selected rationally,including weight per unit,speed and gauge in drawing, roving, spinning process, compact tension and negative pressure et al. Finally combed cotton cashmere compact knitting yarn can be spun successfully,the yarn quality can reach high-grade knitting yarn use demands.
