How does the Leather Abrasion Tester determine the performance of leather? Leather Abrasion Tester is used to test the abrasion resistance of leather. The abrasion of leather is an important cause of leather damage. 1. Judgment method There are two methods to judge the leather wear resistance index, namely the end point method and the appearance change method. 1.1 end point method: grinding away lmm leather required to rotate the number of times for the thickness index of wear resistance, write down the number of friction rotation as the wear resistance index. 2. Flat abrasion test method Test apparatus: There are many kinds of fabric flat abrasion instruments, and the one that is used a lot in the testing industry at present is Martindale Abrasion Tester , so the flat abrasion method is also often called MARTINDALE friction tester method. According to the total number of friction of the specimen broken, to determine the wear resistance of leather.
