Abstract
Natural dyes have attracted the world because of its ayurvedic and biological functioning characteristics. In this research, the functional bio-actives santalin from red sandal wood (RSW) powder has been isolated and exposed to MW treatment for up to 5 min. The extracts and fabrics were stimulated and used to dye at a given condition. The results revealed that 50 mL of red sandal wood extract (RSWE) at 4 pH containing 2g/100 mL of salt was employed at 65 °C for 65 min. After 4 min, MW treatment has given the highest color yield. The surface morphology of the fiber shows that the yarn surface has been modified without any chemical changes. Mordanting with chemical and biological extract at low amounts has improved shade fastness with new tints. It can be calculated that MW ray has the potential to explore colorant from crude powder in a suitable solvent under mild conditions but also reducing dyeing conditions and mordant, revealing that this green tool is cost, energy and time effective.
