摘　　要：为了提高纯棉针织物持久的抗紫外性能,采用溶胶-凝胶法,分别以钛酸正四丁酯、正硅酸乙酯为前驱物,制得纳米TiO2溶胶和SiO2溶胶,将纳米TiO2溶胶和纳米SiO2溶胶按体积比为2∶1配置成纳米TiO2/SiO2复合溶胶,对纯棉针织物进行抗紫外整理。采用CARY50型紫外-可见-近红外分光光度计对整理前后的织物进行紫外光透过率测试,且用JIS洗涤方法检测抗紫外线耐久性,并对织物整理前后的白度、顶破强度等性能进行测试和分析。结果表明:经复合溶胶整理的纯棉针织物具有更好的抗紫外效果且经过30次水洗后,抗紫外性能良好;整理后,纯棉针织物的服用性能变化较小,基本上保持了织物原有的风格和性能。In order to improve durable ultraviolet(UV)resistance of the cotton knitted fabric,nano-TiO2 sol and nano-SiO2 sol were prepared by sol-gel method using N-tetrabutyl titanate,and Ethyl orthosilicate as precursor separately.Nano-TiO2 sol and nano-SiO2 sol are arranged in a volume ratio of 2∶1 to nano-TiO2/SiO2 composite sol,the cotton knitted fabrics were treated by anti-ultraviolet finishing.The UV transmittance of the fabric before and after finishing was tested by CARY50 UV-Vis-NIR spectrophotometer.The durability of the finishing effect was tested by JIS washing method,and the properties of whiteness and bursting strength before and after finishing of the fabrics were tested and analyzed.The results show that the cotton woven fabrics with composite sol finishing have better anti-ultraviolet effect and good UV resistance after 30 times of washing.After finishing,the comfortability of cotton knitted fabrics changes little,basically maintaining the original style and features of fabrics.
