| 摘 要： | 本文用高锰酸钾溶液对山羊绒纤维进行氧化防缩处理。采用正交实验分析各处理因素对山羊绒纤维毡缩体的体积、纤维强力的影响程度。通过直观分析、方差分析与F检验，实验得到：高锰酸钾浓度是影响处理后山羊绒纤维的毡缩体体积、纤维拉伸断裂强力的主要因素。在温度50℃，时间20min，高锰酸钾浓度为0.3％(w/v)，pH值为3的条件下，处理后的山羊绒纤维毡缩体体积比未处理山羊绒纤维毡缩体体积增加近1倍，防缩山羊绒单纤维的拉伸断裂强度与未处理山羊绒纤维的拉伸断裂强度基本相同。

| Abstract: | In this paper, potassium permanganate was used for oxidizing shrink-proofing of cashmere fiber. The effect of oxidizing factors on cashmere fibers felting volume and fiber strength was analyzed through orthogonal experimental. Through intuitive analysis, variance analysis and F test, experimental results showed that potassium permanganate content was main factor influencing cashmere felting volume and fiber strength. When temperature was 50℃, time 20min, potassium permanganate content was 3%, and pH=3, the fibers felting volume of oxidized cashmere was almost two times as big as that of original cashmere fibers, and tensile breaking strength of single oxidized cashmere fiber was almost as big as that of single original cashmere fiber. |
