Abstract
The current study deals with the soaked wool fabrics were dyed with natural dyes extracted from the bark of Symplocos racemosa. The optimization was carried out for the different variables; concentration of dyematerial, time for extraction of dye, dyeing time, concentration of mordants methodsof mordanting. Out of the three methods of mordanting, the best shades for dye was obtained using pre-mordanting with lemon juice and vinegar andpost-mordanting with aqueous leaves extract of Rhus parviflora and aqueous leaves extract of Erythrina suberosa . The colour fastness tests indicated that all samples change in colour on exposure to light. The light coloured samples were affected more rapidly as compared to the dark ones. The Lodh bark dyed samples exhibited fairly excellent fastness to light and the results of washing fastness tests showed that dyed samples had good to excellent fastness to washing. Keywords: Symplocos racemosa (Lodh), Erythrina suberosa, Rhus parviflora, Wool fabrics, Fastness, Herbal mordants, Natural dye.
