摘　　要：优化了藏区紫草茸色素的提取工艺,并用于藏区羊毛的染色,对染后性能进行分析。得到紫草茸色素的最优提取工艺为提取溶剂乙醇和水的体积比为60∶40,固液比1∶10,温度70℃,时间1.0 h,pH=7。紫草茸色素对藏区羊毛的染色行为符合准二级动力学吸附模型,为化学吸附。紫草茸色素染羊毛的提升力好,适宜染深色,同时染色羊毛具有防紫外线效果。The extraction process of lac dye in Tibetan areas is optimized,and it is used for dyeing of Tibetan wool,and the dyeing performance is analyzed.The optimal extraction process for lac dye is the volume ratio of ethanol to water in the extraction solvent of 60∶40,the solid-liquid ratio of 1∶10,the temperature of 70 ℃,the time of 1.0 h,and the pH of 7.The dyeing behavior of lac dye on Tibetan wool conforms to a quasi second-order kinetic adsorption model,which is chemical adsorption.Lac dye shows good building-up property on wool fabric and is suitable for dyeing dark colors.The wool dyeings have anti-ultraviolet effect.
