The Wyzenbeek test is a standard method used to measure the abrasion resistance of textiles, particularly for upholstery fabrics. The test involves rubbing a fabric sample with a standard abrasive material and counting the number of “double rubs” (one back-and-forth motion) the fabric can withstand before showing wear. The result is indicated on a textile label as “double rubs,” providing a numerical value (e.g., 30,000 double rubs) to indicate durability. Option A (resiliency) refers to a material’s ability to recover its shape, not abrasion resistance. Option C (stain resistance) is unrelated to the Wyzenbeek test. Option D (coefficient of friction) measures surface slipperiness, not durability.
