| Résumé : |
This review concerns the application of vat dyes, sulphur dyes, azoic colorants, direct dyes and reactive dyes to both natural and man-made cellulosic fibres from aqueous dyebaths using exhaust dyeing processes and the role of added inorganic electrolyte in such dyeing processes. In this part of the paper, the various theories/hypotheses/concepts which have been proposed to account for the promotional effect exerted by added inorganic electrolyte on dye uptake are reviewed and scrutinised, from the viewpoints of the essential physico-chemical properties of the five classes of dye used and the fundamental aspects of their application. |
