机织物弯曲性能的研究是纺织科学研究和工业应用中的一个重要问题。织物的不同行为，如悬垂性，舒适性和处理，可以理解本研究。织物的弯曲刚度取决于几个因素，如组织几何形状、纱线的弯曲刚度和纱线密度。本文采用能量法对不同斜纹平纹结构的机织物抗弯刚度进行了估计。机织物结构一般分为刚性、半刚性和柔性三种不同的截面长度。在此基础上，提出了平纹和斜纹织物弯曲性能的双组分和三组分预测模型。然后，基于雪莉仪测量了织物的弯曲性能和单位面积重量这一物理性能。除了使用双组分模型观察到的平纹织物抗弯刚度的实验值与预测值存在较大差异外，实测值与预测值吻合较好，验证了理论模型获得抗弯刚度的正确性。因此，采用计算刚性截面长度与柔性截面长度之比（R1）的假设，提出了平纹织物的修正模型。
Abstract The study of bending behavior of woven fabrics is an important issue in textile scientific researches and its industrial applications. Different behavior of fabrics such as drape, comfort, and handling can be understood by this study. Bending rigidity of fabric depends on several factors such as weave geometry, bending rigidity of yarn, and yarn density. In this study, estimation of bending rigidity of woven fabric with different twill and plain structures, have been carried out using energy method. Generally, the woven fabric structure is divided into three different section lengths i.e. rigid, semi-rigid, and flexible sections. Thereafter, bi-component and tri-component models for predicting bending behavior of plain and twill woven fabric have been presented. Then, bending properties of fabric based on Shirley apparatus as well as weight per area as a physical property were measured. Good agreement between measured and predicted values, validated our theoretical models for obtaining bending rigidity, except considerable differences observed between experimental and predicted values using bi-component model of plain fabric. Therefore, using assumptions in calculation of the ratio of rigid section length to flexible section length (R1), the modified model of plain fabric has been proposed.
