Leather wear testing is an important means of assessing the durability and wear performance of leather materials in use. By performing different types of wear tests on leather, it is possible to understand its resistance to abrasion, its durability and how it performs in actual use. Below are a few common types of wear tests on leather:
1. Martindale Method (Martindale Abrasion Test):
The Martindale method is a commonly used abrasion test for leather and is also applicable to other textile materials. During the test, an abrasion head with a specific shape is used to apply a specific pressure to the leather sample and rub it in a circular motion. The duration of the test and the material and weight of the abrasion head will vary depending on the requirements of the application. The results of the test are usually expressed in terms of the number of cycles of friction that the material is subjected to. 2.
2. Wyzenbeek Abrasion Test:
The Wyzenbeek method is also a commonly used method for leather abrasion testing. During the test, a specially shaped abrasion head is used to apply friction to a sample of leather in a linear reciprocating motion. The test continues until the leather shows significant wear or breakage. The result of the test is expressed in terms of the number of friction cycles experienced by the material. 3.
3. Taber Method (Taber Abrasion Test):
The Taber method is a widely used method for abrasion testing, including leather materials. The test uses a rotating disk covered with an abrasive material (e.g. sandpaper or rubber), which is brought into contact with a sample of leather and a certain amount of pressure is applied. As the disk rotates, the abrasive material rubs against the leather and the test lasts for a certain period of time. The results of the test are usually expressed in terms of the number of cycles of friction or the amount of abrasion experienced by the material.
4. Wear Testing Machine:
Wear testing machines use specialized wear manipulation equipment to test the wear of leather samples. These machines usually simulate actual use, such as walking wear on leather shoes or rubbing on car seats. The robotic equipment simulates the wear and tear of actual use by constantly rubbing, scraping or squeezing the leather sample. The results of the test can be the degree of wear, surface damage or cracking.
5. Manual wear test:
Manual abrasion testing is a simple method of simulating the wear and tear of leather by rubbing it manually. This usually involves rubbing or brushing a sample of leather using sandpaper, brushes, whetstones or other abrasive materials. Testers can assess the wear of the leather by visual inspection and touch.
Each of these leather abrasion test methods has its own characteristics, and the appropriate test method can be selected to suit the specific application and needs. Standardized test procedures and relevant standards should be followed when conducting the tests to ensure the accuracy and comparability of the test results.
