Abstract

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.

摘要

外力会导致织物变形并定义其机械性能。。在这项研究中，通过偏斜延伸试验研究了具有不同纬线设置的不同织造类型及其剪切特性（如剪切角，断裂载荷和偏斜方向延伸）的机织织物。提出了一种新的几何模型，根据偏斜延伸试验结果预测变形织物的剪切角。还进行了实验研究，并在变形织物的捕获图像上测量了织物的剪切角。结果发现，新几何模型得到的剪切角结果与实验结果接近。此外，还测试了织物在经向和纬向的拉伸性能。根据结构参数统计地讨论了偏压-拉伸和拉伸试验的断裂载荷和拉伸结果。观察到，力的方向和织物的结构特性会影响载荷-延伸结果。
