ABSTRACT:
A woven fabric for covering a tooth part formed on a belt body of a synchronous belt is woven with a lengthwise yarn and a widthwise yarn. The lengthwise yarn is made of a crimped yarn of synthetic fiber or a covering yarn in which a crimped yarn of synthetic fiber is wound around an elastic cord yarn. The widthwise yarn is made of a spun yarn of synthetic fiber or meta-linked type aromatic polyamide fiber. The widthwise yarn expose more to the woven fabric surface than the lengthwise yarn. Thus, the belt life is lengthened and the noise reduced.
