为提高植物染料叶绿素铜钠盐对蚕丝织物上染过程的控制，提供染色工艺优化的理论指导，本文研究了叶绿素铜钠盐上染蚕丝织物的动力学吸附过程，探讨了染色机理，并运用准一级和准二级动力学模型对叶绿素铜钠盐染色蚕丝织物的实验数据进行模拟，计算叶绿素铜钠盐染色蚕丝织物的动力学参数。结果表明：叶绿素铜钠盐在蚕丝织物上的染色符合准二级动力学模型，且在染色温度70-90℃范围内，随着染色温度的升高，染色平衡吸附量降低，染色速率常数增大，半染时间减小，扩散系数增大。

英文摘要：

In order to improve the dye up-taking process control and provide a theoretical guidance for dyeing process op- timization of the green vegetable dye sodium copper chlorophyll （SCC） on silk fabrics,the adsorption kinetics of SCC on silk fabrics and the dyeing mechanism were investigated. Pseudo first-order and pseudo second-order kinet/c models were used to fit the experimental data and the adsorption kinetic parameters of SCC on silk fabrics were studied. The results indicated that the adsorption kinetics of SCC on silk fabrics agreed very well with the pseudo second-order kinetic mod- el. In addition,with the increase of the dyeing temperature from 70 ~C to 90 ~C ,the amounts of the dye adsorbed on silk fabrics at adsorption equilibrium was decreased,the dyeing rate constant and the diffusion coefficient were increased and the half dyeing t/me was decreased.
