The Effects of Material to Solvent Ratio on the Performances of Natural Dyes Extraction

The utilization of natural dyes from natural resources in fashion industry is preferred than synthetic dyes as the natural dyes is considered as more environmentally friendly than synthetic dyes. In addition, dyes from natural resources, such as plant, are renewable resources that can be sustainably used. In recent years dye from Mangifera has been used widely as sources for yellow color in fashion industry. However, there are still more studies need to investigate the effects of solvent to material ratio during extraction process to attain a standard color that can be applied in industry. Thus, this study focused on the extraction process of dye from mangifera leaf to optimize and provide recommendation about the best solvent and the ratio of solvent to material used in the dyeing process. Experimental results showed that the best solvent for Mangifera indica extraction process is methanol. In addition, the best material to solvent ratio to obtain maximum yield was 1 : 7.
