Shear rigidity of woven fabrics is an important property that defines the behaviour of fabrics when they are required to conform to three dimensional forms, including the human body in the case of apparel textiles or preforms and prepregs used for production of fibrous polymer composite components. Typically, shear rigidity is measured using complicated and expensive equipment. This paper presents the study of the influence of weave patterns on the shear behaviour of fabrics using a simple and precise testing method. The shear behaviour of eleven cotton fabrics in total, utilizing different weaving patterns and different yarn densities was investigated. Specimens of different dimensions were also tested to determine the influence of the specimen dimensions on the measured characteristics. The investigation resulted in a correlation between the shear behaviour and the different weaving patterns. Specifically, it was shown that weave patterns that are closer to the plain weave (firm weaves) are more restricting to the yarn rotation than loser weave patterns. Furthermore, the results show the relationship between shear behaviour and specimen dimensions as well as yarn density. Increasing the length of the specimens (the dimension of the specimen parallel to the direction in which the shearing force is applied) or decreasing the width of the specimens (the dimension of the specimen vertical to the force application) also leads to an increase of the shear rigidity.

机织织物的剪切刚度是一项重要属性，它定义了织物在需要符合三维形式时的行为，包括服装织物或用于生产纤维聚合物复合材料组件的预成型坯和预浸料坯等人体的三维形状。通常，剪切刚度是使用复杂且昂贵的设备测量的。本文使用一种简单而精确的测试方法来研究编织图案对织物剪切性能的影响。利用不同的编织方式和不同的纱线密度，共研究了11种棉织物的剪切行为。还测试了不同尺寸的样品，以确定样品尺寸对所测量特性的影响。调查结果表明，剪切行为与不同的编织方式之间存在相关性。具体地，已经表明，与平纹组织（牢固组织）相比，较平纹组织（牢固组织）更受制于纱线的旋转，而不是落纱组织组织。此外，结果显示了剪切行为与样本尺寸以及纱线密度之间的关系。增加样品的长度（平行于剪切力方向的尺寸）或减小样品的宽度（垂直于作用力的尺寸）也会导致样品长度的增加。剪切刚度。结果表明，与平纹组织相比，较平纹组织（坚固组织）更受纱线旋转的限制。此外，结果显示了剪切行为与样本尺寸以及纱线密度之间的关系。增加样品的长度（平行于剪切力方向的尺寸）或减小样品的宽度（垂直于施加力的尺寸）也会导致样品长度的增加。剪切刚度。结果表明，与平纹组织相比，较平纹组织（坚固组织）更受纱线旋转的限制。此外，结果显示了剪切行为与样本尺寸以及纱线密度之间的关系。增加样品的长度（平行于剪切力方向的尺寸）或减小样品的宽度（垂直于施加力的尺寸）也会导致样品长度的增加。剪切刚度。
