Abstract-- Wool and silk fabric can be dyed with Adina Cordifolia and Acacia Arabica in absence and presence of inorganic salts or mordants for producing various shades ranging from brown, black, dark reddish brown, light yellow brown, yellow, brown etc. with improved colour fastness properties. Aqueous solution of Adina Cordifolia and Acacia Arabica shows a wavelegth of maximum absorption at 285 nm and 280 nm respectively. Addition of aluminium sulphate and ferrous sulphate to such aqueous solution caused precipitation of the individual colorants from their respective solution. Aqueous solution of Acacia Arabica does not show any fluorescence property.
