Effect of Cationic UV Absorber on Light Fastness Property of Reactive Dye

摘要

This article focuses on the improvement in light fastness of reactive dyed fabric. Cotton fabric was dyed with Liyuan Yellow F S reactive dye and cationic UV absorber CANFIX SUN was subsequently applied by exhaust method in order to improve light fastness property. The light fastness property of the dyed samples before and after the treatment using UV absorber was tested as per international standards. The results show that for all light, medium and dark shades the dye exhaustion and fixation percentages were very good. In light fastness property, the dE value (change in colour) of the dyed sample after treatment is smaller in contrasting to that one before treatment which the tone changed to blue and bright direction. It states that this UV absorber improved the light fastness of dyed fabrics.
