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.
