摘　　要：为了获得具有防紫外线性能的棉织物,采用溶胶⁃凝胶法制备含纳米银粒子的TiO2溶胶,并对棉织物进行了整理。借助红外光谱分析仪、热重分析仪、扫描电镜等仪器测试织物的结构与性能。利用罗丹明B溶液对整理前后棉织物的光催化活性进行了测试比较。结果表明:整理后的棉织物紫外线防护系数达到40以上,且具有一定的耐水洗性,同时对罗丹明B的吸附降解率达80%以上。认为:纳米银掺杂TiO2溶胶整理棉织物具有较好的防紫外线性能和光催化活性。In order to obtain cotton fabrics with ultraviolet-proof property,sol-gel method was adopted to pre⁃pare TiO2 sol with Nano silver particles.And it was used for cotton fabric finishing.Fabric structure and properties were tested by testers like infrared spectrometric analyzer,thermogravimetry,scanning electron microscope and so on.Rhodamine B solution was adopted to test the photocatalytic activity of the cotton fabric before and after finishing.The test results showed that the ultraviolet protection coefficient of the cotton fabric after finishing was reached above 40.And it had a certain washability.Meanwhile,the absorption degradation rate on Rhodamine B was up to 80%.It is considered that the cotton fabric finished by Nano silver doped TiO2 sol has better ultraviolet-proof proper⁃ty and photocatalytic activity.
