Cotton fabrics were dyed with natural coloring matter extracted from curcuma longa (turmeric) using traditional heating method and power ultrasonic method. Factors affecting dyeing properties such as pH values, salt conc., temperature, time of dyeing bath and ultrasonic power were studied. Environmentally friendly mordants were used through pre-mordanting, post mordanting, simultaneous mordanting methods. The fastness properties including light, washing, and perspiration for dyed and mordanted fabrics were assessed. Color strength (K/S)& color data CIE lab (L*, a*, b*) were measured for dyed cotton fabrics before and after dyeing and mordanted cotton fabric.
