The coefficient of energy dissipation, which has previously been shown to characterize the surface properties of staple fibers, is examined for cottons extracted with alcohol, mercerized, washed in a water softener, baked, and partially coated with microscopic particulates. The effect of humidity on the coefficient of energy dissipation is observed and hysteresis effects are shown to occur as the humidity is cycled. Humidity effects are discussed in terms of previously published theory on interfiber frictional behavior.
