The ability of reactive dye molecules (CI Reactive Red 180 and CI Reactive Yellow 23) to undergo self‐association and to associate with different surfactants has been examined spectrophotometrically. The stability constants K DS of the dye‐surfactant complexes were calculated at dye:surfactant ratios varying from 1:0 to 1:10 and for different surfactant types (anionic, zwitterionic, nonionic and cationic). Dye uptake on viscose fibre observed for a dye:surfactant molar ratio of 1:0.5 was found to be related to K DS values.
