Abstract

The present study was carried out to revive the old art of dyeing with natural dye from flowers of Lantana camara Linn. It belongs to family Verbenaceae, commonly known as unnichedi. The dye has good scope in the commercial dyeing of cotton in textile industry. In the present investigation, bleached cotton fabrics were dyed with different chemical mordants. Dyeing was carried out by pre-mordanting, post mordanting and simultaneous mordanting. Fastness properties of the dyed samples were determined by standard IS methods. The dyed samples have shown good washing, light and rubbing fastness properties. The various colour changes were measured by computer colour matching software. The range of colour developed on dyed samples were evaluated in terms of (L*a*b*) CIELAB coordinates and the dye absorption on the cotton was studied by using K/S values. An ICPMS study was also performed for the dye extract. This study has proved that, heavy metals such as antimony, arsenic, cadmium and lead were not present in the dye extract.
