摘　　要：探讨精梳牦牛绒棉混纺针织纱的纺制工艺。简述了原色与脱色牦牛绒纤维结构和性能。利用毛纺和棉纺设备相结合的方法,将牦牛绒制成精梳牦牛绒条与精梳棉进行条混。通过各工序关键工艺参数的优选,成功纺制出混纺比为70/30、50/50、30/70的精梳牦牛绒/棉18.22tex赛络集聚针织纱;分析了混纺比对成纱性能的影响;通过切片观察纱线结构,指出牦牛绒纤维更趋向于纱体外围分布,纱体整体呈现牦牛绒包裹棉的结构。认为:随着牦牛绒纤维占比的减少,混纺纱各项性能指标均得到逐步优化。Spinning technology of combed yak cashmere and cotton blended knitting yarn was discussed. Structure and properties of unbleached and bleached yak cashmere were introduced. Combining wool spinning e- quipment with cotton spinning equipment,yak cashmere was made into combed yak cashmere sliver and blended with cotton sliver. By optimizing the key process parameters of each process, combed yak cashmere cotton 18.22 tex siro condensed knitting yarn was spun successfully. The blending ratios of combed yak cashmere and cotton were 70/30,50/50 and 30/70. The effect of blending ratio on yarn property was analyzed. According to yarn slice,the yarn structure was observed. It is pointed that yak cashmere is distributed in the periphery of the yarn. Cotton is wrapped by yak cashmere. It is considered that each performance index of blended yarn is im- proved with the decreasing of yak cashmere content.
