Determination of Initial Shear Modulus of Woven Fabrics in Various Directions

Shear behavior is one of the most important mechanical characteristics that contribute to performance and appearance of woven fabrics. Because of the anisotropy, shear properties of woven fabric are tested in various directions. This paper describes an experimental study of shear properties of woven fabric when shear force acts on specimens that are cut at different angles to the direction of the weft. Tests are conducted on woven fabric specimens that are fastened in two parallel clamps that are placed in tensile tester. Orthogonal plain weave cotton woven fabric was used. Based on diagram of the measured values of force and corresponding vertical displacement, shear angles and corresponding shear stresses are calculated. Initial shear modulus of woven fabrics was determined experimentally and theoretically in various directions.
