Random Tumble is the device that accurately defines the characteristics of fabric pilling and fuzzing. The test consists of random falls in coated chambers, with the objective of causing physical friction in samples. For this, steel rotors constantly rotate inside the individually lit chambers in order to cause drop in test fabrics moving against the cork lining.
