摘　　要：KMnO4在强酸性环境中具有强氧化性,利用这一特点对山羊绒纤维进行防缩处理,加入焦磷酸钠螯合剂用于控制反应速度,使得处理效果更加均匀。以夹角余弦赋权法确定权重,利用模糊正交法的理论与方法处理实验数据,得出模糊综合评价值,将其作为目标函数。通过模糊数学主效应分析,得到优化条件是温度40℃,时间40 min,KMnO4 2 g/L,pH值2,焦磷酸钠4 g/L。KMnO4 has strong oxidizing properties in highlyacid,which is used for the shrink-proof treatment of cashmere.A more uniform effect can be achieved by adding sodium pyrophosphate as chelating agent to control the reaction rate.In this paper,the included angle cosine method is used to determine the empowerment weight,and the fuzzy orthogonal design theory and method to analyze the figures.The empowerment weight worked with the figures determines the fuzzy comprehensive evaluation values,which is then used for the objective function.By direct-viewing analysis of the orthogonal results obtained by fuzzy mathematical,the optimum conditions is： temperature 40 ℃,time 40 min,KMnO4 2 g /L,pH value 2,pyrophosphate 4 g /L.
