Martindale abrasion tester

Scope of application:
This instrument is used for pilling test and fabric abrasion resistance test on fabric, skin, simulated skin, carpet, non-woven fabric, etc. Sample holders with pneumatic or manual systems for 4 or 6 test heads.

Product description:
This instrument is suitable for testing the pilling degree of substances such as GB/T4802.2, ASTM D4970, ISO12945-2, etc The principle: under a given pressure, the round sample is rubbed against the fabric of the same material with the trajectory of the Lissajous figure, and after reaching the specified number of revolutions, the pilling level of the sample is evaluated. It is also suitable for the abrasion resistance test of GB/T13775, ASTM D4966, ISO12947 and other fabrics. The principle: Under a certain pressure, the round fabric sample rubs against the standard abrasive according to the movement trajectory of the Lissajous curve, resulting in damage to the monster.The abrasion resistance of the fabric is expressed by the number of times the sample is damaged performance.
