摘　　要：针对纺织品整理时直接使用纳米粒子存在易团聚、分散较困难的问题,采用溶胶凝胶法制备纳米TiO2溶胶,再将其制成织物整理剂。用整理剂对棉织物进行整理(浸轧法),用XRD、扫描电镜(SEM)和X射线能谱仪对制得的TiO2及整理前后的织物进行表征,并测试整理后织物的抗紫外线性能及其他服用性能。结果表明:制得的TiO2为锐钛矿晶型;整理后的棉织物具有优异的抗UV性能;UPF值达到50+级别。标准水洗(皂洗)实验结果显示,50次洗涤后织物的UPF值稍有下降,但仍可保持在50+水平。整理后棉织物的断裂强力没有下降,透气性基本不受影响。In order to overcome some drawbacks of using nano particles in textile finishing, such as aggregation of the particles and difficulty in dispersion, nano-TiO2 sol was prepared by sol-gel method. And further a fabric-finishing agent was produced with the TiO2 sol. The cotton fabric was treated with the TiO2 finishing agent by dip-padding proceess. The XRD, SEM and X-ray energy spectrum were used to characterize the prepared TiO2 and cotton fabrics before and after finishing with TiO2 solution. Also, the anti-ultraviolet performance and wearability of the finished fabric were tested. Results showed that prepared TiO2 is an anatase crystal. The treated fabrics possess excellent anti-UV property and therating of ultraviolet protection factor （UPF） attains 50 ＋ . The standard test to washing （soaping） shows that the UPF value decreases slightly after 50 washing cycles, but it still retains 50 ＋ . The tensile strength of the treated cotton fabric did not drop and the permeation of the fabric changed little.
