Technical details :
Random tumble pilling tester determines the resistance of textile fabrics both woven and knitted to the formation of pills and other related surface changes. The pills that occur during normal usage of fabric are simulated in test condition. This is done by random rubbing motion by tumbling test specimen in cylindrical test chamber with cork liners. The degree of fabric pilling is evaluated by comparing test specimen with standard photographs .They are rated 1-5 – 1 being very severe pilling and 5 no pilling.
