A rubber-polyester composite comprising a rubber and a core-and-sheath heterocomponent fiber wherein the fiber core is formed from a linear polyester derived from an alkyl glycol and an aromatic diacid, and wherein the fiber sheath is formed from a compatibilizing acid-terminated or isocyanate-terminated polyester. The fiber sheath may also be composed of a blend of a thermoplastic elastomer and the compatibilizing polyester.

Rubber-polyester composites including a functionally terminated

Bilayer filaments and fused cords thereof are described. The product is particularly useful for tire cord and filaments include a core of a partially crystalline, oriented polymer and a shell or sheath formed of a blend of robber and a relatively low melting polymer. A particularly preferred embodiment includes a poly(ethylene terephalate) core as well as a sheath of copolyester blended with poly(styrene-elastomer-styrene) elastomer.

Heterofilament and fused cord thereof

The present invention is generally directed to multi-component rubber-polyester composites including a sidechain containing copolyester as a compatibilizing component.

Rubber-polyester composites including a sidechain containing copolyester

Multi-component composites containing a linear polyester of an alkyl glycol and an aromatic diacid as one component, rubber as a second component, and a third component which is a compatibilizing polyester (polystyrene copolymer).
