Abstract
Cotton fabric was dyed with Liyuan Blue FL-RN reactive dye. The dye exhaustion and fixation percentages were calculated for all light, medium and dark shades. The dye shows very good exhaustion and fixation properties. Dyed samples were tested for light fastness property as per international standards. The results indicates the dye has a good light fastness property. The effect of UV absorber was studied in order to improve light fastness property. Cationic UV absorber CANFIX SUN was applied on the dyed cotton fabric by exhaust method. The results show that the color depth was similar after UV absorber treatment. In all the cases the use of UV absorber improved the light fastness of dyed fabrics as compared to untreated dyed samples.
