A frictional power transmission belt includes a compression rubber layer that includes a frictional power transmission surface at least a part of which can come into contact with a pulley and that is formed of a cured product of a rubber composition. On a surface of the frictional power transmission surface, a surface layer comprising a cured product of a rubber composition containing a polyvinyl pyrrolidone-based resin and an elastomer component is laminated.

The present invention relates to a power-transmitting friction belt having a compressed layer and a knitted fabric. The surface of the compressed layer is covered with the knitted fabric. The knitted fabric has an overlapping section in which one end and the other end of the knitted fabric overlap each other. The overlapping section has a bonding region containing a bonding component for bonding the end and the other end of the knitted fabric together.

A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, each tension member including a plurality of load carrying fibers, the plurality of load carrying fibers including a plurality of aromatic polyester based fibers. A jacket material at least partially encapsulates the plurality of tension members.
