Core-sheath fibers are useful as textile reinforcing materials in rubber items having rubber adhesion of 180 to 260 N/2 cm. The fiber core is a high-melting (co)polyester and the sheath is a high-melting unsaturated copolyester. The high-melting unsaturated copolyester is made from at least one unsaturated dicarboxylic acid coconstituent, which contains at least 2 mole-%, based on dicarboxylic acid components, of alkylmaleic acid, having a 1 to 18 carbon atom alkyl group; alkylenesuccinic acid having a 1 to 18 carbon atom alkylene group; or their polyester-forming derivatives.
