The measurement of the resistance to abrasion of textile and other materials is very complex. The resistance to abrasion is affected by many factors, such as the inherent mechanical properties of the fibers; the dimensions of the fibers; the structure of the yarns; the construction of the fabrics; and the type of yarns or fabric. Rubbing a weighted abrasive paper in a circular motion over the test fabric tests abrasion resistance. Each circular motion is counted as one cycle
