As we all know, the phenomenon that the residual crack is torn due to the concentrated load of the local yarn in the fabric is called the tearing phenomenon of the fabric; for example: the fabric is hooked by an object, and the local yarn is stressed to cause the fabric to form cracks; Being held and torn in half.
There are several ways to assess the tear strength of fabrics stipulated in the standard:
A: Pendulum method
B: Pants method (including single tongue method and double tongue method)
C: Trapezoid method
D: wing method
Criteria for assessing tearing strength test
