Abstract
An easy and direct method was adopted for dyeing unmodified polypropylene (PP) fabric using pigment dyes blue15 and green 7 in aqueous medium. The dyes are based on copper and are used for dyeing PP at high temperature (100-115 °C). The dyeing parameters include dye concentration, dyeing time and temperature were studied. Color strength (K/S) and colorimetric data (L*, a* and b*) are evaluated at specific λmax. In addition washing and light fastness were determined for PP dyed fabric. Antibacterial activity of pigments blue15 and green 7 dyed PP fabric against S-aureus, E-coli and C-candida were evaluated by optical density method. SEM and EdX were performed for PP dyed fabric with pigment blue 15. PP dyed fabric with pigment dyes is useful for making staff coat uniforms, patients and others products such as mattress covers, bed sheets in clinics and hospitals. This medical dyed PP fabric will prevent propagation of diseases in these medical places and the excess can be exported abroad.
