A study has been made of the effect of relative humidity on the pilling performance of wool knitwear. Reducing the relative humidity from 80% to 11% gives a five-fold reduction in peak pilling of samples using the Atlas random tumble pilling tester. The tester itself has been found to alter the regain of samples with a consequent change in the pilling properties of samples, depending on the duration of the test and the use or not of a compressed air injection into the test sample.
