Tariq [56] found that Microwave treatment plays a very significant role in the
dyeing of polyester fabric because it makes the dyeing procedure very environmentfriendly as well as time, labor and cost-effective [57]. The graphical representation of
data is given in (Fig. 15) shows that high color strength (K/S) by dyeing un-irradiated
polyester fabric (NRP) using an irradiated solution of Disperse Red 153 (RS) after
the microwave treatment for 3 min. Microwave treatment being a volumetric heating
source absorb energy directly and internally which leads to controlled, selective,
uniform and rapid heating of dye bath [26]. Previously it has been observed that it
modifies the fabric in such a way that significant interaction with dye has shown good
color strength. The surface of polyester fabric is evenly tuned after the microwave
heating due to which good color strength is obtained [58]. After microwave treated
for 3 min, the irradiation cause ruptured the cell wall and upon isolation, it causes the
breakdown of large size of colorant molecules into smaller size thereby making their
