Figure 2 bath using zinc + hydrose as reducing agent, the reduction decreases reduction throughou potential increases up to 10 min, and then steadily from 15 min to 30 min. The potential is found to be steady the operation in the dye bath containing FeSO, + hydrose combination as reducing agent. This is due to the effective reduction capacity of both FeSO, and hydrose in the vat dye bath. FeSO, + hydrose is 2.530 (strengt fabric using zinc + hydrose strength 55.67%) and for dyed 0.523 (strength 20.51%). Hence, t he cotton fabric dyed with vat similar effect as that of the dyed strength 100 %). h 99.17%), for dyed is 2.168 (strength 85.00%), for dyed fabric using FeSO, is 1.421 fabric using zinc is he depth of shade of dye using FeSO, + hydrose (strength 99.17 %) combination shows fabric using hydrose
