Analysis of Martindale Wear Tester

Author: Released in:2019-11-05 Click:1589

Martindale wear test refers to the Martinez method according to the standard system and its relationship with the textile products to test, and through this test to test the wear characteristics of the fabric, and wear resistance is an important indicator of textile product quality, it Directly affect the durability and use of the product, wear refers to the fabric or with other substances in the process of repeated friction, resistance to wear characteristics. And for the fabric wear test machine, that is, Martin Dyer wear tester.

Martindale wear tester test principle: round fabric sample fixed on the grinding table, and fixed with a standard friction cloth friction head for friction test. There are three assessment methods: the determination of the damage of the sample, the determination of the quality loss, the appearance of the assessment of the test method:
The test sample was rubbed against the standard friction cloth under specified pressure to determine the wear resistance of the sample after reaching a predetermined number of rotations.

Test Operation Flow:
1, the preparation of the sample
In the standard environment, tiled, no tensile state according to different standards require a period of time. Such as 24 h (G B / T 4 80 2 .2-1997), 16 h (EN ISO 12947-4: 1998)
2, the sample selection
From the whole width of the fabric on a different part of a sample, the sample should be representative. If it is a fancy fabric, the specimen shall include all the different tissues and colors of the cloth;
3, from the test machine to remove the load and load shaft;
4, remove the top plate and test fixture;
5, the device of the sample:
Loosen the retaining ring on the test fixture, hold the sample backing, and place the sample in the test fixture base. When the test fabric is not more than 500 g / m2, a piece of polyester foam is placed between the specimen and the metal plug of the specimen. If the fabric is more than 500 g / m2 or the composite fabric is used, no foam is required. The sample should be subjected to the same tension.
6, wool felt and friction cloth device:
Place the felt and the abrasive on the grinding table, place the trolley on the abrasive, then put the ring, tighten the nut, and press the ring to fix the abrasive on the grinding table.
7, the grinding head on the abrasive pressure;
8. Place the test fixture with the sample face down, place it on the base fixture, adjust the test fixture round groove to align the load shaft so that the load shaft is inserted into the circular groove of the test fixture;
9, in accordance with the standard set the number of times to start the switch, start testing, to set the number of times after the automatic shutdown:
10, remove the sample, compare the standard sample in the rating box


Operation Notes:
1, friction cloth can not be used repeatedly, every time you need to complete a test to replace a friction cloth;
2, wool felt can be used repeatedly, if the surface has been worn or has been contaminated when you need to replace, you can use double-sided;
3, insoles should first go to cloth, and then Martin Dyer wear test;
4, after the completion of the test surface of the sample with a broken, broken yarn, fluff or pilling serious, serious wear and other abnormalities, then judged to be unqualified.
5, sample preparation, we should pay special attention to cutting the edge do not produce hair changes, in order to avoid unnecessary loss of quality and appearance changes.
6, the instrument operation process attention to operational norms and personnel safety.


1, must be regularly on the instrument for external cleaning and cleaning, to ensure that the cleanliness of the test equipment
2, regularly check the test equipment to see if there are abnormal;
3, the use of personnel in the use of the process should be used in accordance with the correct use, not illegal use, so as not to damage the instrument, resulting in shorten the life of the instrument;
4, the use of personnel in the use of test equipment, the instrument should be placed well, and the appropriate cleaning equipment to ensure that the instrument clean;
5, in the case of not using the instrument, the instrument should be turned off the power, and continue to keep the instrument clean.
