Wear test classification by wear modes

The wear modes are different and the abrasion test instrument can be divided into three categories: plane abrasion, flex abrasion and fold abrasion.   1. Plane abrasion refers to the abrasion on the flat surface of specimen to test it resistance to abrasion. This mode simulates the wear situation of elbows and hips against clothes. At present, the most used instrument is Mardindale Abrasion Tester. Common standards are ASTM D4966, ISO 12947, GB/T 21196.   2. Flex abrasion refers to the abrasion of specimen flexed under a certain of tension force. It simulates the wear situation of elbows and hips against clothes. Common standards are Common standards are.   3. Fold abrasion is the wear-resisting fastness test of the rim of folded textiles. It simulates the wear situation of collar, sleeve and leg opening. It bends the fabric at 180 °, fold and iron. The folding line section grinds with the abrasives to cause wear loss.   The test conditions of the three test instruments are different, and the test results cannot be substituted for each other.
