Textile fabrics are highly anisotropic and therefore have strong mechanical properties. When there is deviation Angle fabric samples in the cutting, there is a kind of extreme, textile sample tension loading direction will be stretched to 45 ° direction in relation to the direction of the Lord. Then, once loaded, the yarn in the sample will not stay at both ends, so the yarn must establish its internal tension through the friction of the yarn at the interleaving point.

Through samples of yarn is pulled out and the result of the fracture in the machining process for the overall strength of fabric, the fabric strength by the offset direction Angle theta, function of sample width W and length L, and other factors known to affect. In addition, in the same sample, when the main parameters such as sample width W change, the intensity generating mechanism and fault type will also be different.

Note extension:

Anisotropy: refers to all or part of the chemical, physical and other properties of substances change with the change of direction, showing different properties in different directions. Anisotropy is a common property in materials and media and varies greatly in scale from crystals to various materials in daily life to earth media. It is worth noting that anisotropy and heterogeneity are two different ways of describing matter, which are not equivalent.
