A warp-directional stretch fabric that defines two right faces and is formed from warp yarns defined by a nylon and fill yarns defined by an aramid. The fabric can be incorporated into a toothed belt, for example a transmission belt, to produce a belt that has enhanced structural and resistance capabilities while capable of being produced at a lower cost than prior art belts. A method of producing an improved toothed belt including the fabric is also provided.

A reinforced elastomeric article with a film layer having a microporous matrix of ultra-high-molecular-weight polyolefin compounded with a siliceous filler. The article may be a belt, hose, tire or the like. The film layer may reside on a contact surface or other surface of the article or may be embedded within the elastomeric article.

A power transmission belt having a base made of polyurethane and a textile overlay includes a first coating of a first thermoplastic material on the surface of the textile overlay. The first coating forms an impregnation, which has a melting temperature from 80 C. to approximately 145 C., penetrates at least partially into the textile. A second thermoplastic material on the first coating has a higher melting point. The first and second coatings can be applied successively to the textile overlay before casting of the polyurethane or can be overlaid as individual films or as a multi-layer film, and they may be applied to the textile overlay by heat and pressure. The coating acts to reduce abrasion and prevents the through passage of the belt polyurethane.
