Main purpose
The instrument is used for testing the wear resistance of yarn and various ropes in dry and wet conditions.
Technical characteristics
The instrument is used for testing the wear resistance of yarn and various ropes under dry and wet conditions, and is controlled by a computer for testing and data processing. Through testing, the average wear resistance of the yarn, coefficient of variation of wear resistance, maximum value, minimum value, etc. can be displayed.
