Analysis of the change in lea strength, weight loss percentage and wash fastness properties of 100 percent cotton reactive dyed yarn with various shade depth (1% to 4%) is carried out to represent correlation between the specified yarn properties with shade depth change in two different yarn counts. It is observed that increase in shade depth increases the yarn lea strength but shows a decreasing rate in wash fastness and weight loss (%). Finer yarn shows wash fastness rating of 4/5 whereas coarser yarn shows higher value in weight loss (%) and yarn lea strength.
