Analysis of Tearing Mechanism of Fabrics

After the clothes are worn over a period of time, the yarn in the fabric becomes thinner due to friction, so that the local yarns in the fabric are cracked. In the course of the use of the textile, if the long-term localized load, it may reach its strong limit and be torn to form cracks, so that the fabric is damaged; if the fabric is hooked, or the fabric is partially held, The fabric will also be torn in half; the fabric is subject to such damage, often referred to as tearing. In the use of military garments, children's clothing, tents and umbrella fabrics and the performance testing of coated fabrics, the tear strength of the woven fabric needs to be tested. At present, the more common fabric tear strength test method is a single seam method, trapezoidal method and drop weight method, single seam tear breaking mechanism and the factors that affect the tear strength.     In the single seam method tear, the fabric cracks at the formation of a force triangle. When t
