Detailed explanation of Martindale Abrasion Tester used in textile and clothing testing experiments

Martindale Abrasion Test refers to the test of textile products according to the Martindale method standard system and its relationship, and through this test to test the abrasion resistance of fabrics, and abrasion resistance is an important factor in the quality of textile products Index , which directly from affects the durability and use effect of the product. Abrasion resistance refers to the characteristics of resistance to wear between fabrics or in the process of repeated friction with other fabrics. The machine used to test the abrasion resistance of fabrics is the Martindale Abrasion Tester.

Martindale Abrasion Tester is mainly used for textile abrasion test and widely used in textile and leather industry. The test experiment of abrasion resistance is also a classic test method, which has different requirements for different international markets. The Latin American market, the European market and thefor example, domestic market are not just the same, here is the engineer\'s summary of Standard Group (Hong Kong) Co. , Ltd. Various types of standards commonly used in the world for Martindale abrasion testers are listed for reference.

Testprincipe van Martindale Abrasion Tester

Under a certain pressure, rub the movement trace of the Lissajous figure and after reaching the specified number of revolutions, evaluate the pilling level of the sample.

Test Procedure Martindale Abrasion Tester

1. The sample sits for more than 8 hours; 2. Cut a piece of steel from the flat part of the steel. If it is an insole, it must be cut to the transfer part;

3. Take it off the test machine Lower the load and the load shaft;

4. Remove the top plate and the test fixture;

5. Remove the device from the sample: loosen the fixing ring on the test fixture, remove the test fixture For sample compression, place the sample in the test fixture base, place a sample gasket between the sample and the test fixture base, then put the sample compression piece on the sample gasket and fix it with a fastenerstigingsring;

6. Installation of wool felt and rubbing cloth: Loosen the fixing screw to fix the fixing ring, place the wool felt on the base and spread the rubbing cloth, press a pressure of 2.5 kg plate in the center of the rubbing cloth, replace the fixing ring and tighten the fixing screws;

7. Replace the top plate, insert the load shaft (12KPA) through the round hole of the top plate

 8. Insert 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, so that the load axis fits into the circular groove of the test fixture;

9. Set the number of times according to the standard, start the switch, start the test, and stop automatically after reaching the set number of times.

Precautions for Martindale Abrasion Tester

1. The friction cloth cannot be used repeatedlyused. test is completed, a new Replace a friction cloth;

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 perform wear test;

4. After the test is completed, if the surface table of the sample shows abnormal phenomena such as wear, broken yarn, fluff, severe pilling and severe wear, it will be judged as non-qualified.
