External forces cause deformations on fabrics and define their mechanical properties. . In this study, woven fabrics having different weave types with different weft settings and their shear properties such as shear angle, breaking load, and extension at bias direction were investigated by bias-extension test. A new geometrical model was proposed to predict the shear angle of deformed fabrics from bias-extension test results. An experimental study was also carried out and shear angle of fabrics was measured on captured images of deformed fabrics. It was found that the shear angle results found by the new geometrical model were close to experimental results. Besides, tensile properties of fabrics along warp and weft directions were tested. Breaking load and extension results of bias-extension and tensile tests were discussed statistically depending on the structural parameters. It was observed that the direction of the force and structural properties of fabrics affect the load-extension results.
