Abstract

There are many advantages of dyebath-reuse, including less water to heat, less effluent to treat, and a reduced consumption of energy, dyes, and chemical auxiliaries. Because of the potential economic and environmental advantages involved in this process, clearly it is deserving of further investigation. Dyebath-reuse using pH-sliding system has been investigated in the dyeing of polyamide with a single acid dye in a previous study. (omitted)
