| Summary: | Control of the warp and weft yarn tension is an important factor. In this research, effect of warp yarn tension variations on the quality of greige and dyed woven fabrics was investigated. Six fabric samples (three Plain and three Twill weaves) were woven on shuttle loom at varied warp yarn tension. The fabric samples were then pre-treated and dyed (Drimarene Red Cl 5B, 3% owf) using laboratory singeing machine and HT dyeing machine. Greige fabric quality such as fabric inspection, fabric length, fabric width, GSM (Gram per Square Meter), EPI (Ends per Inch), PPI (Picks per Inch), and dyed fabric quality such as L*, a*, b*, C, h o , (K/S) ?max and fastness properties were assessed according to the standard. It has been observed that fabric samples, both Plain and Twill weave; woven at improper warp yarns tension gives rejected greige fabric quality and 1-7% lower (K/S) 550nm values as compared to the fabric weave at requisite warp yarn tension such as 38-39cN for Plain fabric and 78cN for Twill fabric for 42x38 and 64x36 tex construction. Hence, among other weave faults, warp yarn tension variation has influence on the greige fabric quality as well as caused improper and uneven dyeing behavior. |
