Abstract

The aim of coloration for a textile material is to achieve high-quality dyed fabric with good levelness, fastness, and ecological and economical process. In this study, the potential use of molasses as an ecological reducing agent was evaluated for CI Leuco Sulfur Black 1 with respect to the redox potential values of the dyeing liquid, dyeability, fastness values, and waste liquid parameters. It was concluded that molasses can be used instead of commercial products in the exhaustion method and is easily applicable for bulk processes in dyeing mills. Furthermore, the color yield can be improved by increasing the absorption value and impregnation temperature and by using mercerized fabric in the pad-dyeing method.
