摘　　要：银杏黄素对羊毛织物染色效果很好,生成的颜色产物在430 nm处有特征吸收峰。银杏黄素对羊毛织物的直接染色最佳工艺为:银杏黄素质量分数4%(omf),pH=5,染色温度80℃,染色时间60 min。采用媒染特别是后媒染工艺可起到增色效果,染色羊毛织物的色牢度可达到4级以上,比直接染色提高了1级以上,且染色织物具有较强的抗菌和防紫外线功效,UPF值达40以上,紫外线透过率小于5%,经20次水洗后抗菌率仍高于30%。Ginkgetin has a good dyeing effect on wool fabrics,and the generated color product has a characteris⁃tic absorption peak at 430 nm.The optimal direct dyeing process of ginkgetin on wool fabrics is as follows:ginkgetin concentration of 4%(omf),pH value 5,dyeing temperature 80℃,and dyeing time 60 min.Using mor⁃danting,especially post-mordanting,can enhance the color depth.The color fastness of dyed wool fabrics can reach Grade 4 or above,which is 1 level higher than those with direct dyeing.The dyed fabric has good antibac⁃terial and ultraviolet protection properties,with UPF value over 40 and ultraviolet transmittance less than 5%.Af⁃ter washing for 20 times,the antibacterial rate is still higher than 30%.
