摘　　要：利用KMnO4在饱和NaCl溶液中的强氧化性对山羊绒纱线进行正交氧化处理,研究山羊绒纱线的防缩工艺。以纱线断裂强力、毡缩率和白度为测试指标,分析温度、时间、KMnO4用量和助剂等因素对处理后山羊绒纱线各项性能的影响。通过正交试验确定了山羊绒纱线防缩处理最佳工艺为:温度40℃,处理时间30min,KMnO4质量分数为2%(按织物质量计算的质量分数),助剂浓度为6mL/L。Potassium permanganate in saturated NaCl solution is used to shrink-proofing treatment cashmere yams. The breaking strength and felt shrinkage rate of the treated cashmere yarns were tested, and the effects of treatment temperature, time, the content of potassium permanganate and additives concentration on all the above properties of the cashmere yarn were analyzed. By an orthogonal test and comprehensive analyze obtained the optimal craft of cashmere yarns acidic potassium permanganate shrink processing is ： the temperature was 40 ℃, the processing time was 30 min, potassium permanganate concentration was 2% （ o. w. f） , additives content was 6 mL/L.
