This method is equivalent to the international standard IWS. TM. No.112-1980 "Testing method for determination of the resistance to abrasion of textiles" (Martindale tester).
1 Application scope
This standard is mainly applicable to wool and wool blend woven fabrics and knitted fabric, as well as other non-woven fabrics; it is not applicable to synthetic fibers types of pure and blend fabrics and fluffy wool fabrics.
2 Principle
Circular specimen mutually rubs with the standard abrasive under certain pressure according to the motion trail of Lissajous curve, which results in the sample damaged.
3 Apparatus and Auxiliary Materials
3.1 Fabric plane grinding machine
3.2 Standard abrasive
It is a kind of combing plain fabrics made of hybrid wools, with the specification as follows:
