The Comparison Between Chemical and Natural Extraction In Textile Dyeing With Indigofera

Abstract

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. Vat dyes are known to be the most solid dye with high endurances compared to other textile dyes according to how the colour will fade caused by acid or alkaline substances. The fermentation process of Indigofera dye could be done using chemical or natural ingredients. Sodium Hydrosulphite could be used in chemical fermentation, while Javanese brown sugar is used in natural fermentation for Indigo dye. This study uses comparative method with material experimental approach. Comparison between the use of Indigofera dye with natrium hydrosulphite fermentations and Indigofera dye with Javanese brown sugar fermentations will be analyzed. this study is purposed to find the advantages and disadvantages in both Indigofera dye substances made of brown sugar fermentation in the vatting process and hydrosulfite fermentation in the vatting process. the results of this study can be used as references in dyeing textile using indigofera for business people, craftsmen, artists, and students in developing their product designs.
