摘要
采用甜菜红色素对双蛋白纤维进行染色，探讨染色温度、时间、pH值、氯化钠和染料用量对双蛋白纤维的染色性能的影响，分析甜菜红色素对双蛋白纤维的染色热力学，测试染色织物的色牢度。甜菜红色素对双蛋白纤维的优化染色工艺为：甜菜红1．5％，pH=2—3，染色温度30℃，染色时间90min；甜菜红色素在双蛋白纤维上的吸附符合Langmuir吸附模型。
Dyeing of double protein fibers is carried out with betalain from beet. The influences of dyeing temperature, time, pH value and dosage of sodium chloride and betalain on dyeing properties of double protein fibers are discussed. The dyeing thermodynamics of double protein fiber with the betalain is analyzed and the color fastness of the dyed fabric is determined. The results show that the optimal dyeing process is betalain1. 5 %, pH 2 -3, dyeing at 30 ℃for 90 rain. The adsorption of be- talain on double protein fibers meets the Langmuir adsorption model.
