Description

Technical Field

[0001] This utility model relates to the technical field of yarn testing equipment, and in particular to a yarn abrasion resistance testing device. Background Technology

[0002] Yarn abrasion resistance testing is an important method for evaluating the abrasion resistance of yarns, and is commonly used in textile quality control and research and development. An abrasion tester is an instrument specifically designed to test the abrasion resistance of yarns. It assesses the abrasion resistance of yarns by subjecting yarn samples to friction against a friction cloth under specific pressure. Test results are typically expressed as the number of friction cycles or the abrasion resistance index.

[0003] In existing yarn abrasion resistance testing equipment, the test yarn is usually wound around a winding post for connection and fixation. During the test, the connection is prone to loosening, and the yarn length is not easy to control, which affects the testing efficiency. In addition, the counterweight at the end of the yarn lacks a reasonable height control structure. If its position is too high or too low, it will cause errors in the test results and greatly reduce the accuracy of the test results. Utility Model Content
