1、Martindale flat abrasion method
Test instrument: Martindale abrasion tester
Martindale flat abrasion method and taber abrasion method test leather wear resistance comparison analysis
Test principle.
The circular specimen in the specimen jig, under the specified load, with Lissajous (Lissajous) graphic plane movement and abrasive (i.e. standard fabric) for friction, the specimen jig can be freely rotated around its axis perpendicular to the horizontal plane, according to the total number of friction of the broken specimen, to determine the abrasion resistance of leather.
Test method.
The test will be a certain size of test sample in the specified pressure and standard abrasive contact with each other, and make the test sample to Lishajou trajectory relative to the abrasive movement, so that the test sample subject to multi-directional uniform wear.
2、Taber abrasion method
Test apparatus: taber wear apparatus tester
Comparative analysis of wear resistance of leather tested by Martindale and taber abrasion methods
Test principle.
Pre-grinding 25 rpm, the specimen to be tested is placed on the horizontal platform of the TABER abrasion testing machine and rotated, two grinding wheels are given a specific pressure to press on the test piece optionally, the axes of the grinding wheels are parallel to the horizontal plane, one grinding wheel facing outwards and the other facing inwards, all changes in the test piece are recorded within a certain period of time.
