技术纺织品具有在载荷下通过剪切而变形的能力，这使它们与薄片状材料（如纸）区别开来。这种特殊的特性有助于它们变形并呈现出它们想要创造的复杂部件的形状。产业用纺织品的剪切性能对其悬垂性、柔韧性和处理性能有很大影响。本文研究了针脚（即有无针脚）、试验速度和施加的预拉力等因素对0/90°技术纺织品剪切性能的影响，以形成参考试验。为此，要准备两种不同形状的0/90°技术纺织品样品，并对其进行格里斯画框测试。观察到针脚的存在对织物的临界剪切角和最大剪切力有很大的影响。试验速度和预拉伸力的增加也增加了试件所受的剪切力。随着试验速度的增加，临界剪切角逐渐减小，预张紧力的大小对临界剪切角没有影响。
Technical textiles have the ability to deform under load by shearing, which distinguishes them from thin sheet materials such as paper. This particular property helps them to deform and take the shape of the complex part that they were intended to create. Draping, flexibility and handling of technical textiles are greatly affected by their shearing behaviour. In this paper, the influence that factors such as stitch (i.e., presence or absence of it), testing speed and the pre-tension force applied have on the shear behaviour of 0/90∘ technical textile is studied to form a reference test. To achieve this, 0/90∘ technical textile samples in two different forms are prepared and subjected to the Trellis picture frame test. It was observed that the presence of stitch greatly affected the critical shear angle and the maximum shear force experienced by the textile. Increase in testing speeds and pre-tension force also increased the shear force experienced by it. However, the critical shear angle decreased with the increase in testing speed, while the value of pre-tension force applied had no effect on the critical shear angle.
