How are the results of a Wyzenbeek test indicated on a textile label?

The Wyzenbeek test is a standard industry method (ASTM D4157) used to measure the abrasion resistance of a textile, primarily for upholstery. The test involves a machine that rubs a cotton duck abradant or a wire screen back and forth across the surface of the test fabric. One complete back-and-forth motion is counted as a single "double rub." The test is concluded when the fabric shows noticeable wear, such as two yarn breaks. The resulting number of double rubs indicates the fabric's durability and suitability for different levels of use (e.g., residential, commercial, heavy-duty).

A. As resiliency: This measures a fabric's ability to spring back after being compressed, which is a different performance characteristic than abrasion resistance.

C. As stain resistance: This evaluates a fabric's ability to repel or release soil and stains, a property measured by separate, distinct testing methods.

D. As coefficient of friction: This is a measurement of the slipperiness between two surfaces and is not the unit used to report abrasion resistance from this test.

Standard Test Method for Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder Method). In Section 11

"Report

" the standard specifies that the test results must include the "average number of cycles (double rubs) to the end point."

"The Wyzenbeek test results are reported in the number of double rubs (one back-and-forth motion)..." (p. 218).

explaining that the Wyzenbeek method quantifies abrasion resistance in terms of double rubs

which are then used to classify fabric durability for specific end uses.
