摘要
将溶胶-凝胶法应用于纺织品抗紫外整理当中,可以在纺织品表面形成一层薄膜,对紫外线有良好的屏蔽作用.本文采用溶胶-凝胶法,将钛酸四丁酯作为前驱体制备二氧化钛水溶胶,研究了钛酸四丁酯、水、螯合剂、催化剂的用量和反应时间等因素对制备过程的影响;采用激光粒度仪测定二氧化钛水溶胶的粒径分布,用稳定时间评价二氧化钛水溶胶的稳定性,并优化其制备工艺,得到最佳工艺条件:n[钛酸四丁酯]∶n[螯合剂]∶n[催化剂]∶n[水]=1∶5.5∶1.66∶90,室温下反应1 h.通过测定紫外线透过率并计算UPF值来评价织物的抗紫外线性能,结果显示整理后涤棉织物的UPF达到60,具有良好的抗紫外性能.
Sol-gel method was used in textiles finishing and would form a kind of thin film on the base of textiles, so the textiles would obtain anti-ultraviolet performance. In this paper, TiO2 hydrosol was prepared by sol-gel method with Ti(OBu) 4 as precursors. The influence of reaction time, the dosage of Ti(OBu) 4, water, chelant and catalyst on the preparation was studied. Laser particle sizer was employed to determine size distribution of titanium dioxide hydrosol and stabilization time to evaluate the stability of titanium dioxide hydrosol, and the preparation process was optimized. The optimum conditions were as the following : n [ tetrabutyl titanate ] : n [ chelator ] : n [ catalyzer ] : n [ wa- ter] = 1:5.5: 1.66:90 and the reaction time was one hour, the temperature was room temperature. The study used Martindale pilling test method to measure the pilling grade and evaluated the performance of anti-ultraviolet by measuring the ultraviolet transmittance and calculating the UPF values. The UPF value of polyester/cotton fabric treated by the optimum TiO2 hydrosol could reached 60, which means a remarkable anti-ultraviolet property.
