Main Application:
Martindale Abrasion Tester_Martindale Abrasion Tester_Fabric Flat Grinding Instrument is used in textile, footwear, clothing and other industries, suitable for testing the abrasion resistance and pilling degree of knitted fabrics, woolen fabrics, imitation leather, synthetic leather, etc. under pressure.

Test principle:
1. Under a certain pressure, the round fabric sample is mixed with a standard Lissajous abrasive. The motion trajectories of the curves rub against each other, resulting in damage to the sample, and the abrasion resistance of the fabric is expressed by the number of times the sample is damaged.
2. Under a certain pressure, the circular sample is rubbed against the fabric of the same material in the movement trajectory of the Lissajous figure. After reaching the specified number of revolutions, the pilling level of the sample is evaluated.

4. Travel range: horizontal: 60.5 ± 0.5 mm, vertical: 24 ± 0.5 mm
5. Effective friction diameter of the grinding block:
Type A 200g (1.96N) friction head (9kPa)¢28.8 -0.084mm
Type B 155g (1.52N) friction head (12kPa)¢90 -0.10mm

7. Relative moving speed between holder and grinding table: 20-70r/min (adjustable)

Test procedure:
1. Cut a sample from the flat part of the sample. If it is an insole, it must be cut to the transfer part;
2. Remove the load and load shaft from the testing machine;
br />3. Remove the top plate and testtop position;
4. Sample device: loosen the fixing ring on the test fixture, remove the sample pressing piece and put the sample into the test fixture base, put a piece of sample gasket between the sample and the test fixture base, then put the sample gland on the sample gasket and fix it with a fixing ring; br />5. Wool felt and friction cloth device: loose Open the fastening screw and fix the fastening ring, put the wool felt on the base and spread the friction cloth, press a 2.5kg pressure plate in the center of the friction cloth, replace the fastening ring and tighten the fastening screw ;
6. Reinstall the top plate, insert the load shaft (12KPA) through the round hole of the top plate;
7. Place the test fixture with the sample facing down on the base fixture and adjust the circular shape of the test fixture The groove is aligned with the load axis so that the load axis is in the circulargroove of the test fixture is inserted;
8. According to the default setting times, start the switch, start the test and stop automatically after reaching the set times.

1. The friction cloth cannot be used repeatedly, and a friction 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 the Martindale abrasion test is carried out;
4. The test is completed If the surface table of the final sample shows abnormal phenomena such as wear, broken yarn, fluff, severe pilling and severe wear, it will be judged as non-qualified.
5. Pay attention to the balance of the test machine during the test.
6. During the test, all materials should be prepared before the power of the test machineenabled.
7. After turning on the power of the testing machine, set the number of tests to run.
8. During the test, pay close attention to whether the test equipment is installed correctly.
