摘　　要：用不同结晶结构的纳米TiO2对棉织物进行抗紫外线整理,然后用红花红色素染色,并观察耐光色牢度。结果表明:经纳米TiO2抗紫外线整理的棉织物其K/S值小于整理前的棉织物;金红石型纳米TiO2整理棉织物的K/S值高,光老化时色差值变化较小,与整理前棉织物的色差值相近;随着聚乙二醇(PEG)分子质量的增大以及TiO2/PEG含量的增加,K/S值减小,光老化时色差值变化大;在CIE和孟塞尔(Munsell)表色系中,也表现出相同的染色性能。Cotton fabric was treated by nano TiO2 with different crystalline structures to obtain antiultraviolet performance,and then subjected to dyeing with Safflower red dye.The light fastness of the dyed fabric was observed.The results indicated that the K /S value of cotton fabric treated with nano TiO2 is less than that of untreated sample.The cotton fabric treated with Rutile-nano TiO2 had higher K /S value,and less photo-aging color difference than the cotton fabric before treatment.Increasing the molecular weight of polyethylene glycol （PEG） and TiO2 /PEG content,the K /S value decreased and photo-aging color difference increased.In CIE and Munsell Systems,they showed the same dyeing performance.
