▎ 摘　　要

NOVELTY - Power transmission belt (200) comprises a belt body, a tensile cord embedded in the belt body, and a jacket (216) defining a pulley contact surface, where the jacket has been treated on at least the pulley contact surface with an aqueous dip comprising a dispersion of polyetheretherketone (PEEK), an epoxy, and a rubber latex and dried. USE - The power transmission belt is used as tooth cover jacket on synchronous belt. ADVANTAGE - The power transmission belt provides improved textile to rubber adhesion for belt components and/or improved wear resistance for belt jackets. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an aqueous fabric treatment for a synchronous belt jacket comprising an epoxy, a rubber latex, and an aqueous PEEK dispersion. DESCRIPTION OF DRAWING(S) - The drawing shows a fragment view of the power transmission belt. 200Belt 212Tooth rubber 213Adhesion layer 214Teeth 215Land 216Tooth jacket 217Fabric 218Tensile member 219Surface treatment 220Back side 222Back rubber 224Back jacket
