Abstract:

To obtain the behavior of pilling of plain knitted wool fabric, the modified Martindale abrasion tester was adopted to measure the number of pills on the surface of the fabric and worn-off, getting the total number of pills. The experimental results showed that with the abrasion rub n≥13000, the number of pills on the surface was not obviously changed and developed steadily due to the balance between the increase of new pills, which was approximately linear, and the decrease of pills worn-off. The worn-off pills curve was likely to be a smooth S-shaped curve, which is leveled at both ends. The total number of pills was monotonically increasing, however, there was an obvious saturation point. In the platform region, the number of pills on the surface was steady and the morphology of pills was basically unchanged. However, the volume of pills was firstly decreased and then increased. The weight and the density of pills were monotonously increased. The platform region was the most stable region for pilling test.
