How to Perform Leather Abrasion Resistance Test?

The Martindale abrasion test is a method that simulates the degree of wear and tear that leather is subjected to in everyday use. It assesses the abrasion resistance of a leather material by simulating a repetitive process of rubbing and abrasion in a laboratory using a specific test apparatus. The following are the basic steps of the Martindale Abrasion Resistance Test:

 

1. Sample Preparation: Prepare a sample of the leather to be tested. Cut the sample into the appropriate size and shape, usually round or square. Ensure that the thickness and texture of the sample corresponds to the leather in the actual application.

 

2. Sample fixing: Fix the sample in the test apparatus, usually a Martindale abrasion tester. Ensure that the surface of the sample is smooth and free from loose parts.

 

3. Test condition setting: Setting the parameters of the test, such as test speed, bearing pressure, etc.. These parameters can be determined according to specific test requirements and standards.

 

4. Friction Head Installation: Installation of a friction head of suitable material into the friction head position of the test instrument. The friction head is usually made of standardized abrasive paper or fabric.

 

5. Commencement of Test: The test instrument is started, bringing the friction head into contact with the sample and subjecting it to periodic rubbing and friction.

 

6. Observe and record: The wear resistance of the sample is evaluated by continuously observing and recording the friction and abrasion during the test. Common evaluation indexes include the number of times of abrasion, the degree of abrasion, and so on.

 

7. Result analysis: Data analysis and comparison based on test results. Test samples can be compared with control samples or with standard requirements to assess the wear resistance of the samples.

The Martindale Abrasion Test is a commonly used and reliable method of testing the abrasion resistance of leather. It can provide information on the abrasion resistance and life prediction of a material to guide product design and selection. Of course, there are other different abrasion resistance test methods available, and the choice of method needs to take into account factors such as the nature of the material, the test requirements and the standard regulations.
