Management of bitter bush weed (Chromolaena odorata) by natural dyeing of silk using metallic mordants
Author(s): Saurabh and Shahnaz Jahan
Abstract: Bitter bush is an alien, noxious and aggressive weed, which has destructing effects on the agricultural crops, forests, and other exposed areas. This weed can be used as a profitable source of eco-friendly natural dye, as potential use of it as dye source can also solve the problem of its invasion which is otherwise very difficult. The process of silk dyeing with twigs of Bitter Bush was optimized to produce varying shades of dye on silk fabric by using selected metallic mordants. Colour fastness of dyed and mordanted samples to light, washing, crocking and perspiration was also evaluated. Different variables viz. concentration of dye material, extraction time, dyeing time, mordants concentration and method of mordanting were optimized based on percentage of absorption of dye by the silk fabric as well as percentage of marks obtained by the dyed sample through visual evaluation. Colour fastness of samples was found satisfactory, so bitter bush dye can be profitably used for dyeing of silk fabric.
