Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus 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.

CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

Teinture -- Fibres textilesIndex. décimale : 667.2 Colorants et pigments Résumé : To obtain a new type of macromolecular reactive dye with high fixation and good light fastness, poly(styrene-co-maleic acid) was synthesised by co-polymerisation of styrene and maleic anhydride, then, through nitration, reduction, diazotisation and coupling reaction, novel macromolecular reactive dyes were prepared with a solubility greater than 60 g/L. The dyes were used to dye cotton fabrics; the results showed their fixation was more than 92%, and both the rub and wash fastness of the dyes were good. The light fastness of the red and blue dyes with the ethoxy group on melamine was grade 4, and for the yellow dye reached grade 5. The poly(styrene-co-maleic acid) macromolecular reactive dyes exhibit very good application prospects in practice.
