Fig. 14 Effect of MW treatment before a and after bleaching b and mercerization c followed by
dyeing using Reactive Black WNN (Black 5)
penetration of molecules into the fibers which are gathered in form of clusters [54].
Upon washing with cold and hot water most of the dye molecules are stripped off
and low K/S observed. So after mercerization 4 min. of MW treatment should be
given to the fabric using irradiated dye solution to give good results (Fig. 14c). In this
comparison, it had been found that before and after bleaching the MW treatment has
improved its dyeing behavior and should be used for dyeing. This fabric pretreated
by microwave treatment can not only reduce the time, cost energy as well as labor but
also give acceptable results. The colorfastness agencies of fabric has been assessed
after the dyeing at optimal conditions, enhanced good to excellent due to the effect
of microwave radiation treatment (Table 11).
10 Effect of Microwave Treatment on Disperse Dyeing
of Polyester Fabric
Muneer et al. [55] studied the effect of MW treatment on dyeing of the polyester
fabric using Disperse Orange 25 dye at 80 °C for 25 min. This study revealed that
good tinctorial strength was obtained by dyeing irradiated polyester fabric with irradiated disperse dye solution. Fastness properties evaluated onto shade developed at
optimized condition the microwave treatment has excellent potential to improve the
substantive behavior of polyester fabric using disperse dye.
