摘要
通过原位乳液聚合制备了TiO2粒子表面接枝率为13.5%的PBA/TiO2接枝复合胶乳,以其为整理剂,通过浸轧对棉织物进行抗紫外线整理。研究表明,经PBA/TiO2接枝复合整理剂整理的棉织物具有优异的抗紫外线性能和耐洗性能。扫描电镜观察发现,经PBA/TiO2整理的棉纤维表面TiO2粒子附着量大,分散更均匀。认为是纳米TiO2粒子表面存在的PBA接枝聚合物抑制了TiO2在棉纤维表面的团聚倾向,提高了TiO2与纤维聚合物的相容性和结合牢度,因而经接枝整理剂整理的棉织物具有良好的抗紫外线性能。
Poly（butyl acrylate）/TiO2（PBA/TiO2） grafting composite latex with grafting percentage of 13.5% was prepared by in-situ emulsion polymerization, and the ultraviolet resistant finishing of eotton fabric was performed with this grafting composite latex via dip padding. The results showed that the treated cotton fabric has excellent ultraviolet resistant property and washing resistance. Large amount of TiO2 was successfully attached onto the surface of cotton fabric and evenly distributed, as observed by SEM. It was considered that the presence of PBA grafting composite on the surface of TiO2 nanoparticles inhibited the agglomerating tendency of TiO2 on the surface of cotton fiber so that the compability and adhesion of TiO2 with fiber were enhanced, imparting the finished cotton fabric good ultraviolet resistant property.
