Evaluation of color measurement from test samples and transmission, an indicator of dye exhaustion, from final dyebath was focused on reproducibility of color from dyeing to dyeing and maximum dye exhaustion. Experimental effects were 1) pH of dyebath, 2) high dyeing temperature for the test fabric, an acetate tricot, and 3) time at the high dyeing temperature.
