摘要
采用乙醇回流法提取诃子有效成分,并研究诃子提取液染色及媒染后真丝织物的抗紫外线辐射性能。结果表明:诃子最佳提取工艺参数为乙醇体积分数50%,温度50℃,固料比1∶40,时间2h;诃子提取液对织物的染色优化条件为提取液体积分数为30%～50%,温度80℃,pH4,时间40min,且染色后真丝织物的UPF值达到27.4;进一步经铝离子媒染后,UPF值增加到37.9;经过30次水洗之后,直接染色以及媒染织物的UPF值仍保持在20以上。表明诃子提取液染色后织物具有良好的抗紫外线性能。
This article uses ethanol refluxing method to extract effective ingredients of terminalia chebula and researches anti-ultraviolet performance of silk fabric after mordant dyeing with extracts of terminalia chebula. The results showed： the optimum extraction parameters of terminalia chebula is that the volume fraction of ethanol 50 %, temperature 50 %, ratio of material 1 ： 40, time 2 h; the optimized dyeing condition of extraction in terminalia chebula is the volume fraction 30 %-50 %, temperature 80 ℃, pH 4, time 40 min, and the UPF of silk fabric is 27.4 after dyeing; after further post mordant dyeing of aluminum ion, the UPF goes up to 37.9; after 30 times water wash, UPF of direct dyeing and dyeing fabric remains above 20. This indicated that the extraction of terminalia chebula had good anti-ultraviolet performance after dyeing.
