ASTM D4970, ISO12945-2 Martindale Abrasion And Pilling Tester

Test principle

The circular fabric sample is rubbed against the standard abrasive according to the trajectory of the Lisajous curve under a certain pressure, causing the sample to be damaged, and the abrasion resistance of the fabric is indicated by the number of wear resistance of the sample.

The sample and a certain friction material are subjected to low-pressure continuous commutation friction, and the degree of wear and pilling can be compared with standard parameters. The instrument adopts the movable sample fastening component, which can take out a certain friction sample at any time without affecting other samples, not only realizes the rapid and independent detection of the sample, but also ensures the accuracy of the synchronous measurement of the friction.
