摘　　要：利用硅烷偶联剂对棉织物进行改性预处理,并用轧-烘-焙及轧-烘-高压汽蒸二种工艺将纳米TiO2处理到改性棉织物上。通过扫描电镜(SEM)对棉织物进行表征,并测试了织物的抗紫外线性能和光催化性能。结果表明:采用轧-烘-高压汽蒸工艺有利于纳米TiO2在棉织物上的坚牢结合,并有较明显的耐久性;当硅烷偶联剂质量浓度为2.5 g/L时,改性棉织物经纳米TiO2处理后的耐洗性最好。在洗涤20次后,棉织物的抗紫外线性能略有下降,光催化性能和机械性能几乎无变化,白度略有提高。Tough combination between Nano-TiO2 and fabrics is the key technology in development and application of nano-functional textiles. The cotton fabric is pretreated by silane coupling agent and then treated with pad-dry-baking or pad-dry-high pressure steaming process to prepare nano-TiO2 modified cotton fabric. The surface structure of the treated fabric is observed by scanning electron microscopy （SEM）, and the changes in anti-UV properties and photocatalytic properties of the treated cotton fabric are characterized and studied. The results show that the pad-dry-high pressure steaming process is conducive to better combination between nano-TiO2 and cotton fabric and it shows excellent durability. With the concentration of silane coupling agent 2.5 g/L, the washing resistance of nano-TiO2 modified cotton fabric is the best. After 20 times washing, the treated fabric features a slight decrease in anti-UV properties, the similar photocatalytic properties and mechanical properties, as well as the improved whiteness.
