Abstract:

This work investigates the effect of warp and weft density on the bending properties of polyester viscose woven fabrics. 25 lightweight woven fabrics of different densities were produced and evaluated with three methods; KES, extraction, and a newly-suggested method. The test results of the three methods were compared. A correlation between the quantitative parameters of the three methods indicates that the concentrated loading method is better able to show the effect of warp and weft density increase. It is observed that as the density (warp and weft / cm) increases, so the buckling zone of the fabric under concentrated tensile loading moves up (the buckling phenomenon occurs late). In other words, the specification of the buckling zone of the fabric is dependent upon the changes in warp or weft density. It also shows that the post-buckling slope increases due to the increase in warp or weft density. In addition, the ending slope decreases as the fabric density increases.
