Scope of application:
This instrument is suitable for testing the abrasion resistance and pilling degree of knitted fabrics, wool textiles, artificial leather, synthetic leather, etc. under pressure.

working principle:
Under a certain pressure, the circular fabric sample and the standard abrasive rub each other according to the motion track of Lissajous curve, causing the sample damage. The wear resistance of the fabric is expressed by the wear resistance times of the sample damage.

Standards:
GB/T 21196.1-2007 Textiles - Determination of Abrasion Resistance of Fabrics by Martindale Method - Part 1
GB/T 21196.2-2007 Textiles - Determination of Abrasion Resistance of Fabrics by Martindale Method - Part 2
