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 as
well 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.
