The dyeing properties of two aminostyrylpyridinium salts, fluorescent dyes, for acrylic fabrics were investigated by following the cationic dyeing process. The influence of the hydroxyl groups of dye molecule on the dyeing properties were analyzed, and the results showed that the exhaustion value and partition coefficient value decreased a lot when there were two hydroxyl groups attached to the end of dye molecule. The reflectance of the dyed acrylic fabrics with these two fluorescent dyes is higher than 100 % in 600 - 700 nm. Moreover, the chromaticity of dyed acrylic fabric was calculated according to the EN-471 standard (2003) and the chromaticity of dyed acrylic fabric with DEASPI could meet the requirements of color of fluorescent orange.

Keywords:Acrylic fabric; Fluorescent dye; Aminostyrylpyridinium salt; Dyeing
