Dyeing and finishing parameters are important factors which have various impacts on cotton knitted two thread fleece and 1x1 rib fabrics respectively. Various technical properties like physical, dimensional and dyeing properties of 1x1 rib and two thread fleece knitted fabric after different wet processing stages and sequences have been influenced by dyeing and finishing parameters. For this purpose, it was taken two types of knitted fabrics such as 32 (S) , 1×1 Rib and 13 (S) , 28 (S) two

The pretreated fabrics were then dyed and finished to ready to stitch fabrics. At the end of each process stage, samples were collected and analyzed for various physical properties. In every state except dyeing, weight has successively decreased. Total weight loss found for 1x1 rib is 9.59% and for two thread fleece is found 11.49%. Tensile strength also decreased in each stage except in dyeing. Total strength loss found for 1x1 rib is 43.31% and for two thread fleece is 32.72%. Shrinkage has found in both length wise and width wise direction. Length wise shrinkage for 1x1 rib is found -3.35% and in width wise is found -3.50%. For fleece fabric, length wise shrinkage is found -3.25% and in width wise is found -2.70%. The abrasion resistance of different stages for 1x1 rib and fleece fabric are same in dry state. But at dyeing stage, test result is found a little different from other stages at wet state assessment. The results show that, the properties of the fabric changes to a considerable extent after each stage of wet processing. The finishing process whether the dyed fabric is padded with softener and dried in a dryer alters fabric properties to a considerable extent. It improves fabric handle and imparts a soft feel to fabric.
