Martindale Abrasion Testing Machine
1. Martindale abrasion tester applies to: test appearance change(pilling degree/class) of the textiles.
Standards: GB/T4802.2, ASTM D4970, ISO12945-2 ect.
Theory: at a given pressure, circular fabric specimen and the same material, carrying out friction Lissajous trajectory graph, after achieved the required rotation, evaluate the pilling degree of the specimen.
2. Tester also applies to: test the performance of fabric wearing resistance.
Standards: GB/T13775, ASTM D4966, ISO12947 etc.
Theory: circular fabric sample at a certain pressure, rubbing with the standard abrasive according to Lisa if (Lissajous) curve’s trajectory, leading to specimen damaged, use the times of specimen damaged to represent fabric abrasion wear resistance.
