SHEARING PROPERTIES OF THE SKEWED WOVEN FABRICS

This experimental work deals with the effects of skewness on the shearing properties of the worsted woven fabric. Shearing properties of 160 samples are measured by two methods (KES and concentrated loading methods) and the results are compared. Both methods show a positive correlation between skewness and shear rigidity indicating, as the skewness goes up the shear rigidity also increases. Correlation between shear rigidity evaluated by KES and skewness was 0.725, but new parameter (EML) extracted from the concentrated loading curve (Extension at 200 gram-load) showed more sensitivity to fabric skewness and gave a higher correlation (-0.866) to it. In other words, the concentrated loading method shows the relationship between skewness and the shear rigidity (G).
