Extraction of Natural Dye from Ficus cunia and Dyeing of PolyesterCotton and Wool Fabric Using Different Mordants, with Evaluation ofColour Fastness Properties

摘要

Due to the various side-effects of synthetic dye, a need has been felt to discover the new dye yielding plants and optimization of various conditions of dyeing. Ficus cunia was proved to be the good dye yielding plant and wide range of color shades were obtained when different mordants were used with different mordanting methods. Leaves of this plant were used for dyeing wool and polyester cotton (PEC) using different mordants, viz. Potassium Aluminium Sulphate, Ferrous Sulphate, Stannous Chloride and Tannic Acid along with one natural mordant. The natural dye extract gave different shades using different natural and synthetic mordants. The washing, rubbing and light fastness properties of dyed samples were assessed and good to excellent fastness grades were obtained.
