Abstract :A novel water-soluble zinc azaphthalocyanine containing azo groups (Azo-ZnAzaPc) was synthesized and characterized using FT-IR, 1H NMR, 13C NMR, UV–vis, MS and elemental analysis. A dyeing experiment was performed on cationic cotton fabric with this dye via exhaustion process. The dyed fabric was examined for color fastness to light, water, washing, perspiration and rubbing according to ISO standards. Antibacterial properties of the fabric were evaluated against two types of bacteria: Staphylococcus Aureus (S. Aureus) and Klebsiella Pneumoniae (K. pneumoniae) according to ASTM E2149-01 and to AATCC 100 standards. Significant reduction of K. pneumoniae bacteria, rated as 95,91 %, was observed according to ASTM E2149-01 standard. Antibacterial activities and color fastness evalution results of the azaphthalocyanine and of the similar phthalocyanine structure were presented for comparison.
