摘　　要：化学染料对环境的污染较大,为了顺应绿色环保发展趋势,文章选用一种天然植物染料洋葱皮提取物对羊毛纤维进行染色。首先进行洋葱皮染料的提取,分析提取方式、料液比、提取液pH值、提取温度、提取时间对染料提取的影响。通过正交试验得出最佳优化工艺为利用超声波提取、乙醇质量分数为75%、料液比1∶20、pH值2、温度40℃、时间50 min。然后利用直接染色法上染羊毛,探讨染色pH值、染色时间、染色温度对染色牢度及K/S值的影响,由正交试验表明最佳条件为浴比1∶60、染色时间30 min、染色温度80℃。在最佳染色条件下,羊毛纤维的色牢度可达到4级及以上,K/S值为12.664。Due to the large pollution of chemical dyes to the environment,a natural vegetable dye was selected for the dyeing of wool fibers to comply with the trends of green environmental protection.Firstly,onion skin dye was extracted,and the effects of extraction method,solid-liquid ratio,pH value,temperature and time on dye extraction were analyzed.The optimal process was ultrasonic extraction by orthogonal experiment,and the conditions were as follows:ethanol mass fraction of 75%,solid-liquid ratio of 1:20,pH value of 2,the temperature of 40℃,and the time of 50 min.And then the wool was dyed directly,and the effects of dyeing pH,dyeing time and dyeing temperature on the color fastness and K/S value were investigated.The orthogonal experiment shows that the optimal conditions are bath ratio of 1:60,dyeing time of 30 min and temperature of 80℃.Under the optimum dyeing conditions,the color fastness of wool fiber reaches grade 4 and above,and the K/S value iS12.664.
