UV irradiation is useful tool to improve the dyeing behavior of polyester fabric using
disperse dye [17].
A uniform and eco-friendly heating source, based on ultraviolet radiation has
auspiciously improved the disperse dyeing of polyester fabrics said Shahid [67]. She
found that good color strength and fastness properties could be obtained. If Disperse
Yellow 211 (DY 211) is used to dye polyester fabric under the influence of ultraviolet
treatment up-to 80 min. So, ultraviolet-treated polyester (RP) for 30 min. gives good
color strength by dyeing fabric at 70 °C using 70 mL of un-irradiated dye solution
(NRS) of pH 8 in the presence of 2% of dispersant. While for the dye bath of pH 11,
good color strength obtained by dyeing irradiated polyester (RP) for 45 min. using
