摘　　要：探讨不同紧度组织配置下机织物的平面形态特点。选取两种不同紧度的组织配置成正方形方格织物,以组织松紧比、纬纱密度、区域宽度为变化因子,计算织物区域扩约系数,建立了各因子与扩约系数的相关曲线。结果表明:方格织物扩约系数随织物组织松紧比的增大而增大,随纬纱密度的增大而先增大后减小,方格宽度对扩约系数有明显的影响。认为织物紧组织区域向松组织区域扩约需克服纱线的抗弯阻力。Flat shape property of woven fabric in different tightness weave configuration was discussed. Square plaid was configured and selected in two different tightness weave. Ratio between weave looseness and tightness, weft density and zone width were selected as change factors, fabric zone sphincter was calculated. Related curve was estab- lished among factors and sphincter coefficient. The result shows that the sphincter is increased as fabric ratio between weave looseness and tightness adds. The factor is increased then reduced as weft density increases. The factor is affected by grid width obviously. It is considered that bending resistance should be overcome when fabric tightness weave zone is expanding to looseness weave zone.
