A Comparative Study on Effect of Shade Depth on Various Properties of Cotton Knitted Fabric Dyed with Reactive Dyes

This paper aims to scrutinize the change in physical and chemical properties of cotton knitted fabric with a variety of shade depth (1% to 8%) dyeing with reactive dyes. Shade percentage is an important factor which has various impacts on 100% cotton knitted fabric. The technical factors of GSM, color fastness to rubbing, bursting strength test, color fastness to wash, and color fastness to perspiration of cotton knitted fabric are influenced by various shade percentage (1% to 8%). The cotton knitted bleached fabric which was dyed with Remazol Red RR reactive dye and auxiliaries with different shade percentage, then measured GSM & their fastness properties. It was observed that after increasing the shade percentage on cotton knitted fabric, GSM was increased but bursting strength is decreased. On the other hand, color fastness to rubbing, wash and perspiration is decreased repeatedly.
