Wyzenbeek Abrasion Method
topic
The Wyzenbeek machine oscillates a fabric specimen back and forth against a cotton duck or wire screen abradant under tension, recording double rub count to first yarn failure or surface breakdown; warp and weft directions are tested separately to reveal anisotropic wear behaviour.
Role
Dominates upholstery durability specification in North American markets, providing a complementary dataset to Martindale results that reflects unidirectional oscillatory abrasion patterns typical of seating contact zones.
