Wool Dyeing

The study of the interaction between nonionic surfactants and acid dyes is very important in clarifying the mechanism of wool dyeing and colors preservation and also for the washing conditions determination. This paper presents the spectrophotometric and tensiometric data of the interaction between the alkyl polyglucosides surfactants class with new synthesized dye, from the class of azoic dyes derived from 3H-aza-1-oxa-2H-tioxo-5,8-fenalendisulfonic acid. A multiplicity of transitions is observed, when the surface tension of aqueous solutions of nonionic surfactant (APG) in the presence of the acid dye, which interacts strongly with nonionic surfactant to from a dye-surfactant complex, is measured at a constant concentration of the dye and plotted as a function of surfactant concentration. The formation of some surfactant- dye complexes was made evident in the different molecular ratios in the submicellar zone compared to the micellar zone of concentration of the surfactant. There au different equilibrium in the system which compete one another over a large scale of surfactant concentration (adsorption, micellization, small complex formation, large complex �mixed micelles formation).
