ACT Voluntary
Abrasion
Guideline for
Knit Fabrics

The surface wear of a fabric caused by rubbing and contact with another fabric.

Low Traffic / Private Spaces – Knit Upholstery Fabrics
ASTM D4157 (ACT approved #10 Cotton Duck)
15,000 double rubs Wyzenbeek method

ASTM D4966 (12 KPa pressure)
20,000 cycles Martindale method

Notes:
ACT studies indicate that results of multiple abrasion tests performed on some fabric structures may vary significantly – as much as 60 percent or more.

Double rubs exceeding 100,000 are not meaningful in providing additional value in use and not predictive of significant extension of a fabric’s service life.

There is no correlation between Wyzenbeek and Martindale results.

For more information please refer to abrasion white papers on the ACT website.
