| Résumé : |
A new kind of hetero-bifunctional reactive dye containing 2-ethoxy-4-chloro-s-triazine, with better activity matching with β-hydroxyethyl sulphone sulphate at a low fixation temperature, was successfully synthesised and characterised. An ethoxy group was designed to be introduced into triazine to increase the substantivity and the reactivity of the dyes. Thereby, the fixation of mono-s-chlorotriazine/hydroxyethyl sulphone sulphate (KM-type) bifunctional reactive dyes on cotton was improved, and dyeing under mild conditions with high fixation was realised. Nineteen dyes with orange, red and blue colours were synthesised and characterised by UV-Vis and infrared spectroscopy and mass spectrometry. Synthesised dyes were dyed at 60, 75 and 90°C, respectively. Exhaustion and reactivity for all of the ethoxy-containing KM-type dyes was over 90% at the optimal temperature, and fixation was over 87%, which was higher than the ethoxy-free comparative dyes. The optimal fixation temperature of ethoxy-containing dyes was initially reduced to 75°C, and then to 60°C. Compared with comparative dyes, the wash fastness and light fastness were basically unchanged, and the wet rub fastness of the H-acid series was reduced by one grade. |
