Abstract
A toothed belt construction having a tooth cover fabric providing extended useful life of the belt. The cover fabric includes waft fibers extending longitudinally of the belt, having a toughness of at least approximately 30 where the toughness is a function of the square root of the elongation of the weft yarns at break and the strength of the west yarns at break in units of grams per denier. The elongation at break is preferably in the range of approximately 20 to 45%. The strength of the weft yarns at break is preferably at least approximately 6.0 grams per densier. Woolly processed yarns of polyamide fibers have been found to be particularly advantageous in the disclosed construction.
