A new method to evaluate low-stress shearing behaviour of woven fabrics

The abi lity of extracti on and concentrated loading methods for measuring the shearing properties of woven fabrics has been studi ed. Forty light weight woven fabrics of different varieties have been tested by three methods, viz KES, extrac tion and a new suggested method, and the results compared. Correlation between the KES quantitative parameters and the measured features ex tracted from the curves of extract ion and new methods indicates better ability of the new method to measure the shearing properties. It is observed that the buckling zone of fabrics is the key poi nt to evaluate the shearing rigidity. In addition, the new method is capable of yielding the effect of changing producti on parameters.
