拉伸方式与织物强度的关系

The Relations Between Tensile Test Way and the Strength of Fabric

织物在使用过程中,由于用途不同,所受载荷情况也就有所不同。直接研究织物的复合变形是不容易的。通常采用各种简单变形实验。本文对机织物在四种不同拉伸方式(改变拉伸速度、改变试样夹持宽度、改变夹间距及改变拉伸方向)下,所表现的力学性能及影响因素进行了初步的探讨。

When fabric is used, it will bear different loads for different usages. It is not easy to study the complex deformation on fabric dicrectly. Generally, many simple deformation experiments are taken. This paper has mainly discussed and explained the mechanical properties of woven fabric under four different tensile test waies. These are different stretch velocity、different sample clip width、different clip distance and different stretching direction.
