Relevant knowledge of Martindale abrasion test Corresponding to Xiangke models: XK-3060 Martindale abrasion tester, MARTINDALE abrasion tester Test purpose: To test the degree of frictional resistance of substances under a certain pressure. Test scope: This test method is applicable to all kinds of fabric materials. Test equipment: XK-3060 Martindale abrasion tester Test conditions: room temperature (23 ± 2°C) Parameter requirements: 1. Load: 12KPa 2. Test times: 20,000 times for fabric, 40,000 times for liner and 25,000 times for Lixin fabric . Test steps: 1. The sample is parked in the laboratory environment for more than 8 hours. 2. Cut a piece of sample from the flat part of the sample. If it is an insole, it must be cut to the transfer printing area. 3. Remove the load and load shaft from the test machine. 4. Remove the top plate and test fixture. 5. Sample device: Loosen the fixing ring on the test fixture, take out the sample pressing, insertthe sample into the test fixture base, put a sample gasket between the sample and the test fixture base, and then put the sample press on the specimen spacer and secure it with a retaining ring. 6. The device of wool felt and friction cloth: loosen the fixing screw and the fixing ring, put the wool felt on the base and spread the friction cloth, press a 2.5 kg pressure plate in the center of the friction cloth, replace the fixing ring and Tighten the setscrews. 7. Replace the top plate and insert the load shaft (12KPa) through the round hole in the top plate. 8. Place the test fixture with the sample facing down on the base fixture, adjust the circular groove of the test fixture to align with the load axis, and insert the load axle into the circular groove of the test fixture. 9. Set the number of times according to the standard, turn on the switch and start the test. 10. After reaching the set number of times, it will automatically stop en the sample is removed to determine the result. Note: 1. The rubbing cloth cannot be used repeatedly, and a rubbing cloth must be replaced each time a test is completed. 2. Wool felt can be used repeatedly until the surface is worn or stained. 3. The insole must be dressed first and then subjected to the Martindale abrasion test. Result calculation or evaluation: 1. If the surface of the sample after the test shows abnormal phenomena such as abrasion, broken yarn, severe pilling or pilling and severe wear, it will be judged as non-qualified.
