Power transmission belt and method for fabricating the same

摘要

Both types of short aramid fibers and non-aramid synthetic fibers are extruded from a side face of each rib in a V-ribbed belt. The extruded section of the short aramid fiber is formed in curled shape. The extruded section of the synthetic fiber is formed in a sector gradually broadened toward its distal end with its non-melting condition maintained. The root portions of the extruded sections of both types of short fibers are raised from the side face of the rib. The extruded sections of the short aramid fibers are extruded in multiple directions, whereas the extruded sections of the synthetic fibers are extruded in a given direction. The extruded section of the short aramid fiber is formed longer than the extruded section of the synthetic fibers.
