Abstract

To verify the dyeing behaviors of disperse, acid dye, and metal complex dye on nylon/PET(N/P) split type microfiber in the one bath-one step dyeing, the exhaustion curves of the dyes in single and mixed dye bath were measured under different dyeing temperature and pH of dye bath. Exhaustion behaviors of disperse dye in the one bath dyeing of NIP split type microfiber with disperse dye/acid dye or disperse dye/metal complex dye were not significantly affected by dyeing temperature and pH of dyebath. Acid dye showed high temperature dependency of adsorption-desorption behavior during elevation of dyeing temperature in the one bath dyeing of N/P split type microfiber with disperse dye and acid dye. Metal complex dye in the one bath dyeing of N/P split type microfiber with disperse dye and metal complex dye showed also the temperature dependency of adsorption-desorption, but the final absorption was higher than that of acid dye in the same dyeing conditions and increased with decrease of dyebath pH. The staining of disperse dye on nylon was not effected by dyeing temperature but was decreased with the decrease of pH in the one bath dyeing of N/P split type microfiber.
