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 ...
