Abstract

The present invention relates to a textile cord comprising at least two yarns, each yarn comprising multiple filaments, wherein each filament comprises polyethylene furanoate reinforced by carbon nano material and/or boron nitride nano material. These textile cords are particularly useful as tire reinforcements. Moreover, the present invention is directed to a polymeric composition comprising (1) polyethylene-2,5-furan dicarboxylate and (2) a carbon nano material or a boron nitride nano material. This polymeric composition can optionally be further comprised of one or more additional polyesters, such as polyethylene terephthalate or polyethylene naphthalate. This invention is further directed to a rubber component comprising said cords coated with rubber and to tires and other rubber products comprising such cords.
