The study investigated relative color exhaustion of cotton for three different knitted structures (single jersey, rib, and fleece) in the same dyebath. The knitted structures were produced from the yarn of same size. Reactive dyes with three fundamental colors such as red, yellow, and blue were used in the dyeing process simultaneously based on industrial practice. After dyeing all the knitted structures in the same bath, CIELAB values were obtained from all of them and statically analyzed by ANOVA. However, the purpose was to see if there was any difference in color pick-up for different fabric structures. The second part of the study comprised of rib and fleece dyeing with the adjusted recipe based on CIELAB values. In this case, single jersey was considered as the target swatch. Results revealed that adjusted recipe worked well for optimizing the process to get uniform color for all three types of knits. Developed adjustment technique can be used advantageously by the professionals from industry as well as academia.
