摘　　要：为提高天然染料高粱红在锦纶织物上的染色性能,有效控制其上染过程、预测染色效果、指导染色工艺的优化,用高粱红色素进行染色吸附动力学研究,选择准一级和准二级动力学模型对高粱红色素在锦纶织物上的染色数据进行拟合,计算其染色动力学参数,并探讨电解质和表面活性剂对高粱红在锦纶织物上染色动力学的影响。结果表明:高粱红色素在锦纶织物上的染色过程适合用准二级动力学模型描述,且上染速率随着温度的升高而增大,但半染时间却随之有所减少;电解质的加入降低了高粱红的上染速率和平衡上染量,添加不同表面活性剂对上染速率和平衡上染量有不同的影响。In order to improve the dyeing properties,dye up-taking control,dyeing result prediction and dyeing process optimization of the natural dyes Sorghum Red on nylon,the adsorption kinetic experiments were carried out,and the dyeing mechanism was investigated.Pseudo first-order and pseudo second-order kinetic models were selected to examine the adsorption kinetic data.Some dyeing kinetic parameters of Sorghum Red on nylon fabric were studied,and the influence of dyeing of the electrolyte and surfactants were explored.The results indicated that the adsorption kinetics of Sorghum Red on nylon fabrics could be described by the pseudo second-order kinetic model.The dyeing rates increased with temperature rising,but the half dyeing time reduced with temperature rising.Dyeing rate and the adsorbed at equilibrium were reduced with addition of electrolyte,and illustrated different changes with different surfactants.
