黄芩甙对羊毛针织物的染色工艺

Effect of natural plant-baicalin on wool dyeing

采用黄芩甙对羊毛针织物进行染色。利用单因素实验,选用不同黄芩甙染色浓度、不同染色温度、不同染色时间用浸渍法进行染色,通过测定染色织物的摩擦牢度,日晒牢度,皂洗牢度和K/S值,并综合考虑确定最佳工艺条件。黄芩甙对毛织物染色最佳工艺条件为:黄芩甙用量8%(owf)、染色温度70℃,染色时间50 min。固色选择硫酸亚铁和稀土氯化钕作为媒染剂对毛织物进行处理,通过分析媒染剂对各项牢度和K/S值的影响,确定最佳媒染剂为稀土氯化钕,稀土氯化钕的最佳用量为0.8%(owf)。

This paper mainly studies the natural plant-baicalin dyes on wool fabric dyeing capacity. Using the impregnate method and the single-factor analysis for different concentrations of baicalin, color depth, dyeing time and dyeing temperature, it tests and analyses the color fastness of the dyed fabric. The results show the optimal concentration of baicalin is 8% （owf） , dyeing time is 50 min, the best dyeing temperature is 70 ℃ , using the influence of mordant FeSO4 and rare earth chloride for dyeing of wool fabric and the optimum concentration. Base on the test results, the color fastness and color depth of dyed wool fabric, the best neodymium chloride is 0. 8% （owf）.
