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).

| Résumé : |
This paper presents results on the use of trisodium nitrilo triacetate, a biodegradable alkaline organic salt, for pad–steam dyeing of cotton with reactive dyes as a replacement for conventionally used inorganic electrolyte and alkali. Two widely used dyes, CI Reactive Red 147 and CI Reactive Blue 250, were used in the study. The colour yield, dye fixation and ultimate colour fastness achieved by using trisodium nitrilo triacetate were closely comparable with those obtained by using inorganic electrolyte and alkali. The tensile breaking force and wrinkle recovery angle of the dyed fabrics were also measured and were slightly improved when using organic salt. Additionally, the dyeing effluent showed reductions in total dissolved solids content with trisodium nitrilo triacetate. |
