If an uncut woven pile fabric is to be subjected to compressive load in use its compression resilience performance becomes very crucial.In order to optimize the extent of recovery in fabric thickness when the applied force is removed,thirteen uncut woven pile fabric samples were woven and tested on KES-G5 Hand Type Compression Tester (small compress Hammer).The results show that the above parameters influence compression resilience property of the uncut woven pile fabrics,and the structural factors have a more pronounced effect as compared to effect of fibre and yarn type. 相似文献

在线实时纺织瑕疵检测的研究是目前纺织行业相当有实用价值的一个课题。与国外相比 ,目前国内在线纺织品瑕疵检测的系统还比较少。过去国内是先织布 ,然后对布进行成批的检测 ,而织布机上自动在线实时检测系统 ,是在纺织的同时进行疵点自动检测。 相似文献

Knitted fabric is very different from woven fabric due to its more complicated knitting structures. The buckling of knitted fabric sheets subjected to simple shear in the wale direction is investigated analytically in consideration of the large deformation of fabric sheet in critical configuration. The theory on instability of finite deformation is applied to the analysis. All the stress boundary conditions of knitted fabric sheet are satisfied. An equation to determine the buckling direction angle is derived. It is shown that there are two possible buckling modes, flexural mode and barreling mode. The buckling condition equations for the flexural mode and barreling mode are also obtained respectively. Numerical illustrations reveal that only the flexural mode can actually occur and the barreling mode cannot, which agrees with the experimental observations. For a permitted buckling mode on margin boundaries, the critical value of shear amount and the buckling direction angle can be determined. 相似文献

受沿经向简单剪切的织物屈曲分析 总被引:5,自引:0,他引:5
分析了织物受沿经向简单剪切时的屈曲 ,得到确定织物屈曲方向 (屈曲波的方向 )的方程 ,该方程表明织物屈曲方向与临界剪切值有关 .还证明了织物受沿经向简单剪切时会发生离面屈曲 ,并且只存在一种屈曲模态——弯曲屈曲模态 ,得到了该屈曲模态的屈曲条件及屈曲条件曲线 . 相似文献

针对在进行复杂织物建模过程中,会遇到织物组织无序移动,造成建模效果不好等问题,提出了基于约束神经网络的三维织物运动建模方法。通过分析织物运作中特征点运动的对应关系,构造了一个可用于对织物形变进行准确估计的约束神经网络,添加可以对三维织物运动参数进行控制的约束关系,完成复杂无序运动下的三维织物计算机模拟。实验结果表明,本文的方法能够较好地模拟三维织物,取得了较好的效果。 相似文献
