Martindale Abrasion Test Method , Martindale Test for Fabrics

Summary:

Martindale abrasion tester subjects a circular specimen (38mm in diameter, and effective diameter is 28.8mm) to a defined load and rubs against an abrasive medium (i.e. standard fabric) in a translational movement tracing a Lissa-jous figure. The specimen holder, containing either specimen or abrasive medium depending on which method is being used, is additionally freely rotatable around its own axis perpendicular to the plane of the horizontal. The evaluation of the abrasion resistance of the textile fabric is determined from the inspection interval to breakdown, the mass loss the test specimens, assessment of the appearance change.

Standards: GB/T21196-2007,GB/T4802.2-2008,GB/T13775,FZ/T20020,ASTM D4970,ISO12945-2ASTM D4966,ASTM D3886,ISO12947,JIS L1096,IWS,TM196,TM112,M&S.

Application: Used for testing the performance of the wearing resistance, abrasion, appearance change (pilling degree/class) of the textiles and membrane materials.
