This test device is of great significance in the textile industry and can be used for quality control, product development and research.

[0003] After searching, the patent number is CN205786102U, which discloses a cotton yarn tensile testing device. When the cotton yarn is broken, the tensile meter displays the tensile value. A travel grating sensor is set to control the sliding motor on the left to slide left and right, a counter is set to count the number of stretching times, and a pressure sensor is set to sense the contact pressure of the yarn with it. When the pressure is zero, the yarn is broken, thereby prompting the end of the test. It is very convenient, efficient and easy to operate, and suitable for production. However, when the existing cotton yarn tensile testing device is in use, the two ends of the cotton yarn are easily detached from the device during the stretching process, resulting in the termination of the test, which greatly affects the efficiency of the tensile test.
