Which concerning batches of dyed knitted fabric with respective utility consumption has been investigated in this research. To obtain the level and magnitudes of deviation, three batches of cotton knitted fabric dyed with turquoise color having the same recipe, as well as the same condition, were examined. The ailment of shade on different stages of knit dyeing with turquoise color also reported. Process chemicals, parameters, process flow, and visual analysis on the lightbox as well as spectrophoto meter analysis of all three samples were supplemented. Besides color strength as well as utility and time consumption of each batch have an inclusive investigation.
