The Martindale method is the most frequently used method to determine the abrasion resistance of textile fabrics, especially upholstery fabrics.
The method simulates natural wear and tear on a seat cover by rubbing a sample of the test fabric with a given weight against a standard woolen fabric . The test apparatus works at 5,000 intervals. The number of wear (measure: Martindale) of these so-called abrasion cycles , which leads to wear on two threads, is measured . The following applies: the higher the value, the more durable the material.
The national textile institutes specify wear rates for different areas of application of textiles, here are some examples:
| soft upholstery [Martindale] |
hard upholstery [Martindale] |
|
|---|---|---|
| Private use | 10,000 | 15,000 |
| Office use | 25,000 | 35,000 |
| Public transport | 30,000 | 40,000 |
200,000–500,000 Martindales are required for control stations for the police, rescue services, etc.
