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20 min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30 nm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。

Abstract: The white cotton poplin was applied with TiO_2-SiO_2 sol by double-dipdouble-nip method at room temperature,followed by hot water(98~(100 ℃))treatment for 20 min,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 TiO_2 on the cotton fabric.It was observed that the size of anatase TiO_2 on the cotton fabric was about 30 nm.The standard test to washing showed that the nano TiO_2 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.
