摘　　要：针对棉织物抗紫外线性能较差的缺点,运用微乳液法制备了纳米TiO2与纳米SiO2材料,使所制备的纳米颗粒分散性好,纳米粉体颗粒细。通过纳米粉体紫外线透过率测试,得到纳米SiO2与纳米TiO2粉体的最佳配比。对棉织物进行退浆、煮练、漂白前处理,然后运用纳米SiO2与纳米TiO2复合粉体材料对棉织物进行抗紫外线整理。整理后棉织物的抗紫外线能力增强;强度、伸长率和断裂功均有所下降,但变化幅度不大;白度有所下降;折皱回复角增加;透气性也有一定程度的下降。In view of little protection against UV radiation for which cotton fabrics can provide, prepared nano-TiO2 and nano-SiO2 by micro-emulsion method so that the resultant nanometer powder had good dispersing property and very fine particles. The optimal proportion of the nano-TiO2 and nano-SiO2 for anti-ultraviolet protection was determined through testing the ultraviolet transmissibility of the nanometer powders. After pretreatment such as desizing, scouring and bleaching, the cotton fabric was treated with the compound powders of nano-SiO2 and nano-TiO2. The treated cotton had improved anti-ultraviolet performance and exhibited a small margin drop in strength, elongation rate and break merit. The crease recovery angle increased, and the whiteness and air permeability also dropped in a certain degree.
