摘　　要：选取3只不同类型的紫外线吸收剂(二苯甲酮类紫外线吸收剂UV-1、苯并三唑类紫外线吸收剂UV-2和三嗪类紫外线吸收剂UV-3)上染涤纶织物,测试其上染率和各种热力学、动力学参数,通过比较三种紫外线吸收剂对涤纶的平衡吸附量、上染速率常数、扩散系数、半染时间、分配系数、亲和力、染色热和熵变值等,发现UV-1较UV-2和UV-3对涤纶的上染速率、扩散系数快,平衡吸附量较高,半染时间较短;与UV-2、UV-3相比,UV-1对涤纶的上染亲和力更大,染色热、熵值的绝对值更大。Three UV-absorbers（benzophenone type UV-1,benzotriazole UV-2 and triazine UV-3） are chosen to dye on polyester fabrics.Their uptakes on the fabrics and some kinetics and thermodynamics parameters are measured.Through comparison of equilibrium adsorption,dyeing rate,diffusion coefficient,time of half dyeing,distribution coefficient,dyeing affinity,heat of dyeing and values of entropy change and so on,it is found that UV-1 has more equilibrium adsorption,higher dyeing rate and diffusion coefficient than UV-2 and UV-3.It also reveales that UV-1 has larger dyeing affinity,heat of dyeing and values of entropy change than UV-2 and UV-3.
