Synthesis of Cu(II) and Ni(II) Azo Complex Dyes, their Application on Silk Fabrics and Screening for Antibacterial Activity

T. N. Chhowala | K. R. Desai [2]


Abstract: Our present study focuses mainly on the synthesis and dyeing of azo metal complexes on silk fibre. Silk called the Queen of fibres which is symbol of royalty due to its lustrous appearance and peach like softness. The dyeing of silk is an art form. This method produces substituted pyrazolone metal complex acid dyes in very high yield (85 %), when aqueous metal solutions are reacted with 5-Bromo-2{ [5-hydroxy-3-methyl]-1-{ [2-methyl-5-sulfophenyl) -1H-pyrazol-4-yl]diazenyl} benzoic acid ( Dye). Also along with the application of dye on fabrics, study of exhaustion of the dye-bath, study of fixation of dye on the fabrics and the study of the fastness properties of the dyed patterns was carried out. The color yield of the dye furnished over fibre was found to be excellent. The synthesized compounds have been evaluated for antibacterial activity against Pseudomonas aeruginosa, Escherichia Coli and Staphylococcus aureus.
