Abstract

The article studies the most important properties of surfactants – foaming and wetting ability, stability in a highly alkaline environment, surface activity. Spectrophotometric method showed the intensifying effect of environmentally friendly surfactants Glucopon 2015 and Carboxypav on the process of colouring natural textile materials with dichlorotriazine, vinyl sulfone and bifunctional dyes. The effect of surfactants of various structures on the state of the active dye in solution and the technical results of colouring cellulose and cotton silk fabrics has been evaluated. A synergistic effect of the solubilising action of surfactants – nonionic alkyl polyglycosides (Glucopon 215) and anionic carboxylates (Carboxypav) on active dyes was revealed.
