Through the friction inner plate 48 and the friction outer plate 49, wear detection can be carried out to test and measure the ability of the fabric to resist wear and abrasion.

[0035] When the device is in use: first open the pressure plates 13 on both sides to place the textile fabric flatly into the fixing groove 2501, then close the pressure plates 13 and the fixing plates 25, and rotate the twist cap 28 to strengthen the fixation; then start the servo motor 15 to rotate the rotating shaft 7 to drive the supporting slider 3, and the supporting slider 3 moves away from the servo motor 15 to start stretching the textile fabric. When the textile fabric breaks, the tension sensor 29 obtains the maximum tension to obtain the tensile strength, and at the same time records the position of the probe 4 on the scale 6 when it breaks to obtain the maximum stretching length, and then measures the length of the fabric when it returns to its original state to obtain the stretching resilience; when measuring the tensile strength, rotate the rotating rod 32 to measure the strength and durability of the fabric when it is folded or bent. The puncture needle 47 is moved to the top of the fabric, and the servo motor 3 21 is started. The rotating shaft 3 40 drives the lifting slider 39 to descend. The puncture needle 47 squeezes the textile fabric. The pressure sensor 46 records the maximum puncture pressure and obtains the puncture strength. The friction inner plate 48 and the friction outer plate 49 clamp the textile fabric. The blocking rod 17 is adjusted to the appropriate position, and the servo motor 2 19 is started to make the reciprocating slider 37 move back and forth. After one round trip, the data of the counter 20 is increased by one. At the same time, the friction inner plate 48 and the friction outer plate 49 rub against the textile fabric. When the fabric is damaged, the reading of the counter 20 is recorded to measure the ability of the fabric to resist wear and abrasion, which is convenient for evaluating the wear resistance.
