摘　　要：室温条件下白色棉府绸织物二浸二轧自制的TiO2-SiO2复合溶胶，于98—100℃水热处理20min后晾干。织物的紫外线透过率和UPF测定结果显示，复合溶胶整理后棉织物的紫外线防护性能大大提高。采用SEM、AFM和XRD对整理后棉织物进行表征发现织物上有锐钛矿型纳米TiO2生成，其粒径为30m左右。标准水洗实验证明，棉织物上原位生长的锐钛矿型纳米TiO2与织物结合牢固，10次水洗后织物的抗紫外线性能没有下降，反而有所提高。The white cotton poplin was applied with TiO2-SiO2 sol by double-dip-double-nip method at room temperature, followed by hot water （98 - 100℃ ）treatment for 20,in, and then air-dried. The testing of UV transmittance and ultraviolet protection factor （UPF） of the treated fabric showed that its UV screening property improved significantly. The SEM, AFM and XRD were used to characterize the TiO2 on the cotton fabric. It was observed that the size of anatase TiO2 on the cotton fabric was about 30 nm. The standard test to washing showed that the nano TiO2 in-situ growth on the cotton fabric had excellent fastness to washing, and after 10 washing cycles its UV screening property even enhanced instead of decreasing.
