Anthocyanin from red tamarind, Tamarindus indica var. rhodocarpa as a potential natural pigment for use in textile industry
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2017, Vol 23, Issue 1
Abstract
Tamarindus indica var. rhodocarpa (red tamarind) is one of the fruits rich in anthocyanins and these pigments can be used as natural dye for dying fabrics instead of synthetic dyes which are harmful. This study has been carried out to utilise the natural pigment of this fruit as a colourant in the textile industry. The dying ability of the fruit is obtained by dying it on a bleached cotton fabric with and without the use of mordant. The colour absorption values (K/S) were calculated using the Kubelka- Munk equation from reflectance values Tannic acid and ferrous sulphate were used as pre and post mordants respectively. On spectrophotometrical analysis, increased colour intensity was observed on the fabric which has been treated with mordant. The mordanting process resulted into varied values of (% STR-WSUM) colour strength, red/green value (a*), yellow/blue value (b*) chroma (C*) and hues (H*) with significant changes in lightness values (L*).
