摘　　要：采用硅改性法对TiO2/ZnO复合粉体进行表面改性。通过在聚酯中添加改性TiO2/ZnO复合粉体形成共混体系,对TiO2/ZnO复合粉体的抗紫外性及其与聚酯共混纺丝后改性涤纶纤维的力学性能进行了研究。研究表明,经过表面改性后的改性剂最佳质量分数为0.1%,TiO2和ZnO粉体的添加量为1∶1时抗紫外线的效果最好,且粉体添加量越大,纤维的力学性能下降越多。After TiO2/ZnO composite powder was modified by SiO2 on its surface, the mixed system was prepared by addition of the TiO2/ZnO composite powder to polyester. The ultraviolet resistance of TiO2/ZnO composite powder and the mechanical properties of PET/TiO2/ZnO composite fiber were characterized in this paper. The ultraviolet resistance was strongest when the amount of the modifying agent was 0.1% and mass ratio of TiO2 and ZnO was 1. The mechanical property of fiber was decline with the increasing powder content.
