Fluorescent yellow 10GN and fluorescent red G are commonly used two disperse fluorescent dyes. From the perspective of fluorescence reflectivity and colored light, the influences of pH were analyzed in the process of dyeing and finishing, and also the color matching performances of fluorescent yellow 10GN, color blue B, fluorescent red G and disperse red CBN-T were analyzed. Results show that the fuorescent reflectivity and color shade of fluorescent yellow 10GN are not high for the pH dependency, as long as in weak acid dye bath conditions there will be relatively good dyeing;fluorescent reflectivity and color shade of Fluorescence red G is higher for pH dependency, with the reduction of pH, it's fluorescent reflectivity also decreased, and it’s color tended to blue;Fluorescent yellow 10GN and colour blue B spell bright blue, bright green, Fluorescence red G and disperse red CBN-T spell to bright red, bright orange, the two groups are all easy to colour combination, so choosing the appropriate heating rate and heat preservation is very important to dyeing.
