| 摘 要： | 基于圆形截面纱线的平纹织物模型，依据几何学，推导出平纹织物折皱弯曲变形计算方程，提出表征织物松紧结构的新指标——织物密度放松值γ．通过数值计算表明，织物折皱变形与织物密度放松值γ呈线性递减的关系，且挤紧结构状态的平纹织物的纱线最外层最大变形率达到40．75％．

| Abstract: | Based on the plain fabric woven by yams with a circular cross-section, the calculation equations of creasing deformation value are obtained by using the geometry principle and a new index is presented, that is, releasing value of fabric density T which reflects the tightness of a fabric. The calculation results show that the creasing deformation value has a negative linear relation with the releasing value of fabric density T- Further- more, it is also shown that, when a plain fabric is in the state of jamming, the maximum outer deformation rate of the warp yam in the fabric is up to 40. 75%. |
