Fig. 23 Effect of ultraviolet treatment time on dyeing of polyester fabric using Disperse Yellow

bath does not affect. Hence for UV irradiation an exposure for 15 min. of polyester
fabric should be given to get desired results. Good color strength was obtained for
60 min. using a dyeing bath of pH 7 keeping material-to-liquor ratio 1:70 by using
6 g/100 mL of dispersant (Fig. 24). The colorfastness agencies of shade made at
optimal condition reveal that good to fair fastness agencies were obtained after the
treatment of microwave radiation (Table 16).
Adeel et al. [17] observed the role of UV radiation on dyeing of polyester fabric
using Disperse Orange 25. Their studied that good color strength was obtained by
using irradiated dye solution on un-irradiated polyester using disperse dye at different
optimized dyeing conditions. Fastness characteristics of dyed fabric reveal that shade
made at optimized dyeing conditions enhanced the fastness agencies from good to
excellent under the influence of the treatment of UV radiation. They concluded that
