摘　　要：为了解助剂对毛用活性染料上染壳聚糖纤维的影响,研究了匀染剂阿白格B和元明粉对壳聚糖染色性能的影响。结果表明,阿白格B、元明粉的加入不影响毛用活性染料上染壳聚糖纤维的染色动力学模型,但是会使上染速率、反应速率常数和扩散系数下降,半染时间t_(1/2)延长,具有缓染作用;匀染剂和元明粉的加入均能提高染色织物的均匀性,阿白格B不会降低上染率,而元明粉会降低上染率。In order to understand the effect of auxiliaries on the dyeing of chitosan fiber with wool reactive dyes,the effects of leveler Albegal B and sodium sulfate on the dyeing properties of chitosan fiber were studied.The results showed that the addition of Albegal B and sodium sulfate did not affect the dyeing kinetic model of chitosan fiber with wool reactive dyes,but it would reduce the dye uptake rate,reaction rate constant and diffusion coefficient,and increased the half-dyeing time t_(1/2),which had a retarding effect.The addition of leveler and sodium sulfate could improve the uniformity of dyed fabrics,and Albegal B would not reduce the dye uptake,while sodium sulfate would reduce the dye uptake.
