    摘要: A power transmission belt comprising a body comprising an elastomeric material and having tensile members running in a longitudinal direction, the body having a pulley engaging region having a profile; the pulley-engaging region comprising a fibrous nonwoven fabric material; characterized in that the fibers of the nonwoven material comprise acrylic fibers. The acrylic fibers are preferably micro-fibers of less than about 1.5 dpf and having an average diameter of 13.5 microns or less and an average length of about 1 to about 10 mm. The nonwoven material may be commingled with the elastomeric material in the pulley engaging region. Up to about 75% by weight of the fibers of the nonwoven material may comprise non-acrylic fibers such as other synthetic fibers, natural fibers, or cellulosic fibers.
