ABSTRACT
Ash solutions derived from vegetation have been known for their good mordanting action. They are used as finishing agents because they are able to promote dye uptake. It is expected that the types of ash solutions may have been different worker by worker since the workers have employed easy-to-get plants, when we reviewed old literature. However, the ash solutions are being used without clear distinctions between their characteristics. In this study, camellia ash solution and rice straw ash solution were prepared according to traditional methods. Using these solutions as mordanting agents, natural dyeing experiments with Caesdpinia Sappan were peformed. Following the dyeing procedure, the effect of the type of ash solution on the color of the dyed fabric was evaluated. The results showed that the ash solution mordanting effect us not dependent upon the components of the ash solution. It was also demonstrated that the mordanting effect was not based on the action of the metallic ions in the ash solution. The pH values of the ash solutions were adjusted in order to investigate the effect of changes in ash solution alkalinity on the dyeing process. The pH values ranged from neutral or weak acidity to the alkaline range in order to evaluate the characteristics of the mordanting tv the ash solutions.
