Synthesis of zinc phthalocyanine dyestuffs containing some different substituents and colouration of textile materials

Main objective of this thesis is to use metallophthalocyanines (M: Zn, Co, Ni, Cu) containing eugenol firstly for colouration in textile and to investigate color measurement analyses, fastness and antibacterial properties of the colored fabrics. It is expected that antibacterial properties of eugenol and metal ion can be combined in one phthalocyanine structure. Therefore, metallophthalocyanines (M: Zn, Co, Ni, Cu) with tetra and okta peripheral eugenol substituents were synthesized respectively in according to (Şaşmaz et al., 1999a; 1999b). Metallophthalocyanines (M: Zn, Co, Ni, Cu) without substituent were also synthesized in according to (Harikumar, 1990) for comprehending substituent's effect on antibacterial test results. Suspensions of the pigments were prepared with assistance of a convenient dispersant using zirconia ball milling method. Then their particle size distributions were characterized by a laser diffraction particle size analyzer. Cotton fabrics were coloured with pigment printing and then rubbing fastness and light fastness of fabrics were tested according to ISO 105×12 and ISO 105 B02 test methods respectively. Colour strength (K/S values), L*, a*, b*, C*, h values measurements were performed. Antibacterial properties of the fabrics were investigated according to ASTM E2149-01 test method. All synthesized phthalocyanine pigments showed various levels of antibacterial activity against Staphylococcus aureus and Klebsiella pneumoniae bacteria on cotton. Antibacterial protection was achieved only via colouration with these pigments without any additional antibacterial finishing process. In future, potential the coloured antibacterial fabrics may be used in military, healthcare, work/uniforms, domestic products and sports apparel, especially in medical textiles.
