Abrasion tests are carried out with different devices and methods. The Martindale test is a abrasion test in which threads are worn through on flat fabrics or bare wear occurs in pile fabrics. “Martindale’s” name refers to the equipment used for these internationally recognized abrasion tests. The test result is expressed in number of revolutions that the device has made. For example, up to three broken threads in a fabric, or visible pile failure in a pile fabric.
Abrasion tests are also assessed for damage such as pinholes, discoloration, pilling, grip and surface change.
The ABREX abrasion tester is a soft-chemo-mechanical fingertip and hand abrasion tester. The simulation of the abrasive movement corresponds with an accuracy of 99% to use in practice.
Some features are:
- The wear tests are performed at an angle of 45°.
- A dynamically and pneumatically actuated viscoelastic fingertip, rubs or presses with a given pressure on a surface
- The Abrex fingertip makes a tumbling and rubbing motion on a sample. An abrasion test cloth is placed between the sample and the finger. For example, dirt, dandruff, oil, sweat, or different types of test fluids are applied to this test cloth.
- The fingertip can make a contact movement or swipe on the surface.
Examples of application in practice:
- Control panels and control buttons
- Plastic cards such as access passes, credit cards, and the like
- Household equipment
- Leather and leather objects
- Securities, passports, and the like
