Popis: Removal of hydrolysed reactive dye is an important stage in cotton dyeing as it affects the exploitation and hygienic properties of textile products. As a major consumer of water and chemicals, this work process is being studied from the point of view of saving natural resources and environmental protection. In this paper, studied was the effect of washing agents on the basis of surfactants with different ionogenicity as well as pure water on the removal of hydrolyzed reactive dyes having different functional groups. The obtained results suggest that clean water with a larger bath ratio (1:30) and a washing time of 30 min can be an effective remover for hydrolysed monoreactive dye. In the removal of the hydrolysed bifunctional dye, beside the bath ratio and washing times, the concentration of surfactants can also have a significant effect on the process efficiency.
