Abstract:

Cotton fabric was treated by nano TiO2 with different crystalline structures to obtain anti-ultraviolet 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.
