摘要/Abstract

摘要： 活性染料/D5悬浮体系可实现活性染料无盐节水染色，为提高对该工艺下活性染料在棉织物上染过程的控制及染色工艺优化的理论指导作用，用C.I.活性红195进行染色吸附动力学实验，探讨其染色机理。运用准一级动力学模型和准二级动力学模型对C.I.活性红195的在传统水浴和D5悬浮体系染色实验数据进行模拟，计算C.I.活性红195在两种染色条件下的染色动力学参数。结果表明，C.I.活性红195在传统水浴和D5悬浮体系对棉织物的染色均符合准二级动力学模型。活性染料/D5悬浮体系染色平衡吸附量显著高于传统水浴染色，半染时间显著下降，染料在短时间内几乎完全上染。

Abstract: The advantages of reactive dye/D5 suspending system dyeing are water-saving and salt-free, for improving the dye up-taking control, and dyeing process optimization of the reactive dye on cotton, the adsorption kinetic experiments were carried out by C.I. reactive 195, and the dyeing mechanism was investigated. Pseudo first-and second-order kinetic models were used to examine the adsorption kinetic data, some dyeing kinetic parameters of reactive dye/D5 suspending system dyeing and conventional reactive dyeing were studied. The results indicated that the adsorption kinetics of reactive dye/D5 suspending system dyeing and conventional reactive dyeing were found to follow the pseudo second-order kinetic model. The new dyeing process can increase the amounts of dye adsorbed at equilibrium and reduce half-dyeing time.

Key words: reactive dye, adsorption, dye/D5 suspending system, cotton, kinetics
