<p>A power transmission belt comprising a polyester tensile cord having a heat shrinkage at 100° C. of less than 1% and/or a heat shrinkage at 150° C. of less than about 1.5% and/or a dimensional stability index of less than about 6%. The belt has a heat shrinkage after 24 hours at 100° C. of less than 1%. The polyester may be that sold under the trade name A360 or A363 by Performance Fibers, Inc. or equivalent polyethylene terephthalate. The tensile cord is particularly suited for use in V-belts for variable speed drives.</p> |
