【摘要】 众所周知，过量的紫外线辐射会引起皮肤病，甚至会引发皮肤癌。近些年，由于臭氧层的破坏，特别是在两极，出现了巨大的臭氧层空洞，而且这种趋势仍在增加，这势必造成人们的担忧。因此，提高棉织物防紫外线辐射性能便显得尤为重要。本文研究的是纳米TiO₂对棉织物的防紫外线辐射性能。主要工作如下：（1）以钛酸丁酯和乙醇为原料，通过改变原料配比，pH值，温度等条件，采用溶胶-凝胶法制备纳米TiO₂，优化其制备工艺；并通过XRD分析，得出煅烧温度与产物的晶型有关。（2）将纳米ZnO和Al₂O₃与纳米TiO₂进行物理包覆；然后分别采用阳离子表面活性剂、阴离子表面活性剂、非离子表面活性剂、两性表面活性剂四种不同类型表面活性剂对纳米TiO₂表面改性，研究其改性后纳米TiO₂在水中的分散性和紫外吸收情况；并研究了表面活性剂间的复配性能，寻求出表面活性剂复配最佳配比。研究表明，先经过纳米ZnO包覆再加入十六烷基三甲基溴化铵-IW按照最佳配比复配改性，整理到棉织物上，可获取最佳抗紫外织物。（3）对白色和有色织物进行抗紫外整理，研究整理液浓度、粘合剂、焙烘温度、焙烘时间等整理工艺对织物的白度、断裂强力、抗紫外能力的影响，并通过织物耐洗性的分析，找出了最佳织物整理工艺。更多还原

【Abstract】 As you know, it is bad for your body to receive much ultraviolet ray. Much ultraviolet radiation do damage to skin, even lead to cancer of skin. In recent years, the ozone layer is damaged and it becomes thiner and thiner. There are two huge holes on both poles. The ozone layer over our country is also obviously becoming thinner and thinner. As a result, cotton fabrics need the anti-ultraviolet functional finishing. Anti-uv properties of nanometer TiO₂ on the treated cotton fabrics is studied in this paper.The major work includes the following aspects:（1） Nanometer TiO₂ is prepared with sol-gel process ,and process was optimized by using tetra-butyl titanate and ethanol as the raw materials, and by changing the conditions sush as raw material ratio , pH value and reaction temp. The curing temperature is related to crystalline phase through XRD technique.（2） Nanometer TiO₂ is modified with physical process as nano-ZnO and Al₂O₃, organic process as anion, cation, non-ionic, zwitterion surfactant. The influences on surface modification of dispersion properties and absorbance of ultraviolet ray is studied. Research cotton fabrics via the anti-ultraviolet finishing by the two types surfactant. We find that the surface modification with cetyl three methyl amine bromide and IW surfactant of nano—ZnO/TiO₂ has excellent anti-ultraviolet properties.（3） White and colour Cotton fabrics of anti-ultraviolet finishing. The concentration of finishing agent , bonding agent and the curing temperature and time has influence on the whiteness value the draw strength and the transmission percentage of ultraviolet ray of the treated cotton fabrics .And the washing—resistant of the treated cotton fabrics is studed to find the excellent finishing art.更多还原
