Synthesis and Application of Azo Disperse Reactive Dyes derived from p-Aminobenzaldehyde
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 5
Abstract
Disperse reactive dyes were synthesized by diazotizing p-aminobenzaldehyde and coupling with different substituted pyridones and 2-naphthol. The dyeing performance of the dyes was assessed on polyester, nylon, cotton and wool fabrics. The dyes obtained gave various shades of yellow with good depth, brightness and leveling properties on the fabrics. The dyed fabric showed fairly good to very good light fastness and very good to excellent fastness to washing, hot pressing and rubbing. The dyebath exhaustion on the polyester, nylon, wool and cotton fabrics was found to be very good and fixation on wool was better than on cotton fabric.
