To determine how well a fabric can withstand wear and tear from repeated use like sitting or rubbing a double rub test is performed.

  • One double rub = one back-and-forth motion (like someone sitting down and getting up).

  • The test is done using a mechanical arm on a machine, usually the Wyzenbeek or Martindale tester, depending on the standard.

  • Fabric is rubbed until there is noticeable wear, such as thread breaks or pilling.
