Indigo is categorized as a vat dyes, which is needs to pass a fermentation phase in the extraction process before it could be used as a textile dye due to its lack of fastener substances. Fermented dyes are known to be the most solid dye with high endurances compared to other textile dyes according to how the color will fade caused by acid or alkaline substances. The fermentation process of Indigofera dye could be done using chemical or natural ingredients. Natrium Hydrosulphite could be used in chemical fermentation, while Javanese brown sugar is used in natural fermentation for Indigofera dye. In this study, comparison between the use of Indigofera dye with natrium hydrosulphite fermentations and Indigofera dye with Javanese brown sugar fermentations will be explained, by using experimental methods. The results of this dyeing experiment from using two kind of reductors, will be analysed to learn each of its advantages and disadvantages.
