Nitrogen heterocyclic fluorescent compounds and their possible dyeing pathway on acrylic fabrics was investigated. Their chemical spectral properties, including fluorescence and ultraviolet-visibility, were evaluated in this work. The colour fastness properties of these dyes attributable to light reflection and washing were examined. The CIE L*, a* and b* values after the dyeing process were studied and the colour fastness properties were also determined. Two quinoline derivatives showed stronger fluorescence properties and were also demonstrated to be non-cytotoxic towards human HaCaT skin keratinocytes at a reasonable dose. These results led to speculation that these two compounds could be further used as dyes in various textile applications. Coloration Technology
