  Extraction of natural dye from Whitfieldia lateritia plant and its application on cotton fabric was studied. In this research, natural dye was extracted from the leaves of Whitfieldia lateritia using 1% alkali as solvent. The dye extract was analyzed in the area of fabric dyeing using a mixture of alum and tannic acid as mordant, and sodium dithionite as reducing agent. UV-Vis spectroscopy, FTIR spectroscopy and colour fastness to washing, perspiration and daylight were also carried out. It was revealed that Whitfieldia lateritia dye is a direct dye since it dyed cotton fabric without the aid of a mordant. However, the application of mordant improved the colour fastness of the dyed cotton fabric. UV-Vis and FTIR spectroscopy confirmed the possible presence of some percentages of flavonoids, polyphenols and tannins in the dye... Read More»
