| Résumé : |
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. |
