A novel approach for precise determination of in-plane shear behavior of woven fabrics

The ability of a textile product to change shape under motion-based diagonal forces defines the shear behavior of a fabric and its suitability for a wearable garment design. The principal aim of this study is to introduce a new shear frame and investigate the effects of raw material and setting on in-plane shear behavior of woven fabrics. For this purpose, the mechanical properties of systematic and commercially available non-systematic fabrics were measured. A novel approach to determine the in-plane shear behavior of woven fabrics via two complementary shear frame measurements was presented. The results were also compared with a conventional method known as the bias extension method. It was established that the proposed method provides more accurate and precise results. In order to investigate the correlation between in-plane shear behavior and other mechanical properties, bending rigidity and extension ability of fabrics were measured as well. The analyses regarding the relations between selected fabric parameters showed that there are considerably high correlation coefficients. The effect of raw material and setting was likewise found out to be statistically significant.
