Abstract: Natural dye containing Lawsone that imparts yellowish-green colour on to the cotton fabric has been extracted using water, alum and methanol from non-irradiated and irradiated henna powder through UV source. The effect of treatment time, temperature and salt concentration on the dyeing of cotton fabric has been studied using CIELab system for the optimization of dyeing conditions. Different mordants, such as copper sulphate and ferrous sulphate, have been employed for the improvement in colour fastness properties of the irradiated dyed cotton fabrics. It is observed that the UV radiation not only enhances the colour strength of dye on cotton fabric but also improves the fastness properties of pre-irradiated cotton fabrics.
