This paper investigates the application of dye extracted from Tamarindus Indica (bark) in an aqueous solution and used to dye cotton fabric. Application of colours on textiles was achieved conventionally by using natural dyes which are environment friendly. A revival of commercial interest in natural dyes has opened several research avenues. In the present study, the natural dye were extracted from the bark of Tamarindus Indica on cotton fabric has been studied and the study was been carried out to optimize dye extraction prepared in aqueous medium and dyeing conditions for cotton fabric. The effect of variables on extraction and dyeing in terms of pH (4-10), temperature (30oC -100oC) and duration (30-90 minutes) were studied. The dyed cotton samples were subjected to fastness tests and colour strength. Colour fastness property investigations included wash, rubbing, perspiration, light fastness performance and antimicrobial activity. The dyed fabric showed good wash, rubbing, perspiration and moderate light fastness properties. K/S values of the dyed fabrics were also evaluated and the effect of mordant type with different mordanting methods on dyeing was studied and mordanted samples showed better K/S values improved with gallnut compared to alum. Dyed samples showed enhanced colour values, fastness properties and antimicrobial activity with mordants, this outcome specifies dye extracs from the bark of Tamarindus Indica it has potential for use in the textile industry.
