Load carrying cord and power transmission belt incorporating the load carrying cord

摘要

A load carrying cord for a power transmission belt. The load carrying cord has a plurality of strands made up of fiber filaments of ethylene-2,6-naphthalate. Each strand has a denier of 500 to 1500. The fiber filaments in each strand are first-twisted in a first direction. The plurality of strands are combined by final-twisting in a second direction oppositely to the first direction. The resulting load carrying cord has a denier of 3,000 to 10,000.
