【摘要】 选用提纯的弱酸性艳红10B对牛奶蛋白纤维染色,并与羊毛、大豆蛋白纤维进行比较,绘制上染速率曲线和吸附等温线。通过测定牛奶蛋白纤维的染色热力学(亲和力、染色热、染色熵)以及动力学(扩散系数D、半染时间t1/2、染色速率常数K)数据,说明牛奶蛋白纤维的染色性能。研究结果表明,70℃和90℃时初染率都以牛奶蛋白纤维为最,大豆蛋白纤维次之,羊毛最小;70℃时牛奶蛋白纤维的半染时间最短;牛奶蛋白纤维90℃上染速率曲线先升后降,主要原因是染料的解析;提纯的弱酸性艳红10B在牛奶蛋白纤维上的吸附属于Nernst分配型吸附,大豆蛋白纤维趋向于Langmuir型,而羊毛的吸附等温线类型比较复杂。更多还原
