Conclusions
The optimized radiation condition is irradiated powder & irradiated cotton (RP/RC).
Optimum dyeing conditions are 60 C, pH 10 and 30 min.
Low irradiation time for dye solution aswell as for cotton fabric is more effective to get good colour strength and bluer shade. It is found that UV radiation not only improves the colour strength of dye solution but also enhances the colour fastness properties.
