A Study on the Eco-Friendly Natural Dye Extracted from Flowers of Landana camara L on Silk and Wool fabrics

摘要

An increased interest for natural dyes, started several years ago, on the part of the consumers, is just beginning to be felt. The present investigation was carried out to revive the old art of dyeing with natural dye obtained from flowers of Landana CamaraL. It belongs to family verbenaceae, commonly known as unnichedi. The dye has good scope in the commercial dyeing of silk and wool in garments industry. In the present study, bleached silk and wool fabrics were dyed with chemical and natural mordants. Dyeing was carried out by pre-mordanting, post mordanting and simultaneous mordatning. The dyed samples have shown good washing, light and rubbing fastness properties. The various colour changes were measured by computer colour matching software. The heavy metals like antimony, arsenic, cadmium and lead present in the extract were determined by Inductive Coupled Plasma Mass Spectrometer.
