摘　　要：选用双氧水/甲酸对羊毛进行预处理,达到低温染色的目的。通过甲酸与双氧水协调作用,改变羊毛表层结构,使羊毛染色的温度,由传统的沸染降低到70℃,通过单因素实验、正交试验,优化工艺条件,最后得出最佳预处理工艺为:双氧水体积浓度60 mL/L,甲酸体积浓度70 mL/L,60℃水浴中保温40 min,浴比1∶100,预处理试样在70℃下染色上染百分率达到96.52%。Abstract：Dyeing properties of wool fiber pretreated with hydrogen peroxide/formic acid can be improved and the wool fiber can be dyed in low temperature. Through the coordination function of formic acid and hydrogen peroxide, the new method can change the surface structure of wool fiber, anddecreased the dyeing temperature form the conventional boiling dyeing to 70 ℃. The process and formula were optimized through single-factor and orthogonal tests, the optimum conditions were： hydrogen peroxide 60 mL/L, formic acid 70 mL/L, at 60 ℃ water bath in the thermal insulation 40 min, bathratio 1： 100, and the dye uptake of the pretreated sample could be rasied to 96.52%.
