Q: What is circle pilling test method?

A: Fabric sample pilling with nylon brush at a track of circle motion under a certain pressure, then rubbed relatively with a standard fabric to pilling, or with a fabric abrasive to pilling directly. This test method is suitable for chemical fiber filament fabrics and chemical fiber short fabrics, but if fabrics are used as abrasives, it can apply to fabrics easy to pilling.


Q: According to which standard the TF225 machine is made? GB/T 4802.1-2008 only? Or can make according to ISO 12945 also ?

A: It’s based on GB/T 4802.1-2008 only.  ISO 12945 is the other standard for Martindale abrasion tester TF210. They are two different test methods responding to two different machines.
