Abstract
In this study, cotton fabric specimens were pre-mordanted using Sn, Al, Cu, Cr, and Fe, and subsequently dyed using cochineal, maintaining the pH of the dye bath constant using pH buffer solutions of 4, 5, 6, 7, and 8. In the cases of Al, Cr, and Sn mordanting, the dye-uptake was well accomplished in the acidic range of pH 4 and 5. However, the dye-uptake was not accomplished in the range over pH 6. In the cases of Cu and Fe mordanting, however, the pH value did not affect the dye-uptake and the dyeability in the alkaline range was not decreased remarkably. In the case of non-mordant, the dye-uptake was not accomplished at all, and the Cu and Fe mordanting gave rise to the best dyeability. In the cases of non-mordanting and Al, Cu mordanting, there was no change in the
