Description

technical field [0001] The invention relates to a test device and a test method for dynamic breaking strength of simulated yarn. Background technique [0002] Yarn strength test is an important index to measure the quality of yarn products, and it can indirectly reflect the mechanical properties of fabrics. However, due to the complexity of the technological process in the subsequent processing of the yarn into a fabric, after the yarn is formed into a fabric, there is a certain angle between the yarn and the yarn, which causes the fabric to be affected during use. Under the action of a force of uncertain direction and magnitude, the fabric rapidly fatigues and breaks the ring. This makes it particularly important to simulate the dynamic breaking strength test of yarn. [0003] At present, the existing yarn dynamic breaking strength measurement equipment adopts the imported CTT yarn comprehensive quality evaluation system, which can measure the dynamic friction coefficient...
