%X Colored effluents from the textile industry contribute significantly to water pollution, posing a serious environmental challenge. Reducing water pollution is a key focus in the EU's goal of achieving climate neutrality by 2050. In line with this, the idea of reusing the same dyebath for multiple dyeing cycles in textile industry is suggested. Therefore, in this study, two azo pyridone dyes with enhanced water solubility are synthesized, fully characterized and used for dyeing fabrics of different chemical compositions. Firstly, the affinity of dyes towards different fabrics is screened by using multifiber fabric, and thereafter individual fabrics are dyed following the principles of sustainable dyeing. The fabrics dyed in each cycle are further analyzed for color strength. The results demonstrate the feasibility of reusing the same dyebath up to four times, significantly reducing the concentration of synthetic dye in the final wastewater.
