超声波在黄芩甙对羊毛针织物染色中的应用

Application of ultrasonic dyeing on wool knitting fabric with baicalin

采用超声波染色技术,黄芩甙作为染料对纯毛针织物染色。通过与常规染色进行对比实验,证明超声波染色技术可以减少染色时间,降低染色温度,染色织物的摩擦牢度、皂洗牢度和表观得色深度(K/S值)均优于常规染色。通过单因素优选实验,得出最佳超声波染色时间和染色温度,其中最佳染色时间为30 min,最佳染色温度60℃。同时,研究了媒染剂和超声波协同作用在黄芩甙纯毛织物染色中的作用,实验结果表明:超声波和媒染剂的协同作用使染色织物的表面得色深度明显提高。

This paper discusses natural dyestuff baicalin on wool fabric dyeing, using ultrasonic dyeing technology. The experiment verified the effect of ultrasonic. Ultrasonic dyeing technology can reduce the dyeing time and lower the dyeing temperature. And rubbing color fastness, washing color fastness and apparent color depth （K/S value） are better than that of conventional dyeing. By single factor optimization experiments, we can know the best ultrasonic dyeing time and the best dyeing temperature, the optimum dyeing time is 30 min, and the best dyeing temperature is 60 ℃. At the same time, the paper studies the synergistic effect in the baicalin on wool fabric dyeing. The experimental results show that the synergy can make the surface color depth of dyeing fabric improved obviously.
