Abstract:

In this paper, hemicyanine fluorescent dye, namely, trans-4-[p-(N,N-diethylamino) -styryl]-N-methyl pyridinium bromide (DEASPBr), was synthesised and applied to the dyeing of acrylic fabric using the traditional cationic dyeing procedure. The absorption spectra of the novel dye were studied under various pHs, and the dyeing properties, fluorescent reflectance, and colorimetric properties were also explored. The results showed that the adsorption mechanism of DEASPBr on acrylic fibre was in good accordance with the Langmuir type, and the dye had an obvious fluorescent effect. In addition, according to the EN-471 standard, the dye could meet the requirements of the fluorescent orange dye for high visibility warning clothing in terms of chromaticity co-ordinates and luminance factors when its concentration was limited in the appropriate range.
