Study of the effect of sliding velocity on the frictional properties of nonwoven fabric substrates

Frictional properties of nonwoven substrates have been investigated using a sliding friction apparatus. Nonwoven substrates were developed using a modern needle-punching nonwoven technology. The experiment was conducted over a range of applied normal loads. The study was aimed at understanding the effect of testing speeds on the frictional properties of needle-punched nonwoven substrates. Frictional properties were characterized using friction factors, C, n and R. Results indicate that as the speed of the testing increased, frictional resistance increased.
