The aim of this paper was to compare the efficiency of two type of electrolyte in the dyeing of cotton fabrics with reactivedyes. Factors affecting dye ability such as salt concentration, and fastness performances such as alkaliconcentrationwerestudied. The colouryield K/S and colour fastness of the dyed fabric using sodium sulfate were comparable to thoseobtained with sodium chloride. However, the exhaustion and the fixation timewere shorter and the diffusion coefficient waslower in the case of sodium sulfate.
