Dyeing performance of anti-ultraviolet cotton fabric treated with nano TiO_2

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.
