Patent ID: 7695386

Claim:
A power transmission belt, the belt comprising an elastomeric body and at least one fabric layer, wherein the fabric layer is comprised of a fabric and a vulcanized elastomeric material, wherein the fibers in the fabric layer extend in at least one direction of the belt, wherein there are interstices between the fibers in the fabric, and wherein the belt is characterized by the interstices between the fibers in the fabric of the fabric layer containing a vulcanized elastomeric material, wherein the fabric layer is made by the vulcanization within the interstices of the fibers of an elastomeric material comprising 20-80 phcm of a liquid elastomer and a cross-linkable functionalized polyethylene, and wherein the elastomeric material has a complex dynamic viscosity of less than 5 McP (5,000 N*s/m 2 ) for at least 2 minutes at a maximum flow temperature T F .
