Herein we report our study on wool dyeing with natural alizarin in a vat system using the Argan's pulp. Natural alizarin was extracted from the Rubia tinctorum plant using enzymatic hydrolysis and alkaline solution. In order to assess the role of the reducer in the dyeing process, we tested one dye bath without reducer containing just alizarin extract and sodium carbonate solution at pH 8. In the vat preparation using these components, we used Argan's pulp as the reducer. Under relatively soft dyeing conditions for wool (60°C and pH 8) dyeing in the vat system realized a higher degree of dye fixation and wash fastness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
