摘　　要：以原位乳液聚合制得的聚丙烯酸丁酯PBA/TiO2复合胶乳为整理剂,通过浸轧对棉织物进行功能整理,并与经TiO2水分散液、PBA胶乳与TiO2分散液共混物、黏合剂VTECO与TiO2分散液共混物等3种不同整理剂整理的棉织物进行功效和服用性能比较。结果发现,在相同的整理工艺下,经自制PBA/TiO2复合胶乳整理的棉织物表面TiO2粒子尺寸较小,分散较好,织物表面附着层较薄、较均匀,纱线内纤维间黏连较少,因而经相应整理的棉织物具有较好的抗紫外线和抗老化性能,且对棉织物原有的白度、手感等服用性能影响较小,这与PBA/TiO2复合胶乳整理本质上实现的是对纱线内单纤维的均匀薄型包覆有关。Poly（butyl acrylate） /TiO2（PBA /TiO2） composite latex prepared by in-situ emulsion polymerization was used to finish cotton fabric via dip padding,and the functionality and wearability of the finished cotton fabric was compared with those of the other three cotton fabrics treated by mixed finishing dispersions（aqueous TiO2,PBA latex ＋ TiO2,binder VECO ＋ TiO2） on similar finishing process.The results indicated that under similar treating conditions,the TiO2 particles are small,well and evenly dispersed on the fiber surface of PBA /TiO2-treated cotton fabric,forming a thin film with little fiber to fiber adhesion inside the yarn.In essence,the single fiber coverage by PBA /TiO2 coating is realized,thus it has less influence on the wearability such as whiteness and handle.
