摘　　要：采用性能稳定的无机物整理剂纳米羟基磷灰石对棉织物进行功能后整理,用以提高棉织物在光催化作用中的光学稳定性以及对纳米二氧化钛的吸附性,采用正交试验的方法,研究以棉织物为载体的二氧化钛光催化功能材料制备的关键技术。结果表明:采用1∶1的乙醇/水溶剂配置纳米二氧化钛分散体系,纳米粒子的分散效果最好;当分散体系中二氧化钛质量分数为3%时,制备的棉织物在紫外线照射下甲醛的分解效果最佳。Functional finishing of cotton fabric was performed by the stable mineral HAP with a view to improving the photo-catalytic stability of cotton and its adsorption of TiO2 ; the key technologies for preparation of TiO2 photo-catalytic functional material with cotton fabric as carrier were studied through orthogonal experiments. The results indicated that when the proportion of alcohol and water was 1 ： 1 in preparation of nano TiO2 disperse system, the nanoparticles had the best dispersibility; and when the mass concentration of TiO2 was 3% in the disperse system, the prepared sample cotton fabric had optimum decomposability of formaldehyde under UV irradiation.
