Wyzenbeek test assesses fabric’s resistance for abrasion (mostly used in North America).
A fabric sample is placed in the Wyzenbeek machine. The fabric is rubbed in a back and forth motion on a cylinder covered in either cotton fabric or wire screen. The fabric sample is assessed at certain intervals to identify yarn breakage appreciable wear, colour loss and loss of pile.
The test is completed when 2 yarns are broken or when the appearance of the fabric has substantially changed.
This is the general classification:

Wire Screen (residential):
– Light Duty (3.000 double rubs),
– Medium Duty (9.000 double rubs)
