Abstract
Woven fabric for use in a power transmission belt. The fabric has a warp of shrinkable yarns obtained by aligning and twisting individual shrinkable mixed twisted yarns. Alternatively, the warp may be formed of more than two mixed twisted yarns mixed in a ratio of greater than 1:15 of elastic yarns formed of polyurethane fibrous yarns oriented at more than 10%, or rubber yarns and other fibrous yarns. The weft is made alternatively of twisted yarns or monofilament yarns. The fabric has excellent shrinkability, wear resistance, and crack resistance.
