摘　　要：介绍了使用脂肪酶、过氧乙酸、过氧化氢酶对羔羊毛进行改性处理,并对实验结果进行了正交分析,得出了羔羊毛脂肪酶-过氧乙酸改性处理的最佳工艺:过氧乙酸质量浓度为4 g/L;处理溶液pH值5,温度35℃,时间35 min。研究表明,过氧乙酸质量浓度、处理液pH值、处理时间和温度对羔羊毛的拉伸强度和摩擦性能有不同程度的影响,特别是温度、过氧乙酸质量浓度2个因素对羔羊毛拉伸强度、摩擦性能影响较大。This article analysed lipase, the peracetic acid and catalase modification of lamb＇ s wool fiber, and orthogonal the experimental results analysis. Obtained the best way of the lipase and the peracetic acid modification on lamb＇ s wool fiber： the peracetie acid concentration is 4/（g·L^-1） ; pH of solution is 5 ; the processing temperature is 35℃; the processing time is 35 minutes. Research showed that the peracetic acid concentration, pH of solution, the processing time and temperature have different affects on the tensile strength and friction performance of lamb＇ s wool fiber, especially, the processing temperature and the peracetic acid concentration have greater impaction on the tensile strength and friction performance of lamb＇s wool fiber.
