Abstract
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.
