摘　　要：为有效控制酸性染料易染氨纶的上染过程并指导其染色工艺的优化,采用酸性橙Ⅱ对酸性染料易染氨纶染色,通过测定酸性染料易染氨纶在不同染色条件下的上染速率曲线,并将上染速率曲线与动力学模型进行拟合,研究酸性橙Ⅱ对酸性染料易染氨纶的染色动力学。结果表明:酸性橙Ⅱ对酸性染料易染氨纶在低pH值下具有更高的初始上染速率和上染量,提高染色温度可加快纤维上染;酸性橙Ⅱ对酸性染料易染氨纶的染色过程适合用准二级动力学模型描述,其主要通过静电吸附作用上染酸性染料易染氨纶。In order to control the dyeing course of the dyeable spandex fiber with acid dye and optimize the dyeing process,the dyeable spandex fiber was dyed by Acid Orange Ⅱ. The dyeing kinetics of dyeable spandex fiber was studied by measuring the dyeing rate curve of the dyeable spandex fiber under different dyeing conditions and fitting the curve with the kinetic model. Experiment results show that the dyeable spandex fiber has a higher initial uptake rate and higher dye uptake at a lower pH value,and a rise in temperature results in a higher dyeing rate. The dyeing course of Acid Orange Ⅱ on the dyeable spandex fiber follows the pseudo-second-order kinetic model. It is proved that the dyeable spandex fiber is dyed with Acid Orange Ⅱ mainly by electrostatic adsorption.
