-24- A rubber-reinforcing polyester fiber composed of a polyester prepared by using 30 to 150 ppm as antimony of an antimony compound and 5 to 60 ppm as germanium of a germanium compound as the polymerization catalyst. The fiber is characterized in that the terminal carboxyl group content is not larger than 25 eq/ton, diethylene glycol content (DEG) is not larger than 1.3% by weight, the intrinsic viscosity (IV) is at least 0.85, the sum (S) of the intermediate elongation and the dry heat shrinkage is lower than 8%, the product between strength and elongation (T~E) is at least (2S + 5), and the terminal modulus (TM) is not higher than 40 g/d. The polyester fiber is used as a rubber reinforcement.

Fibre en polyester de renfort de caoutchouc composée d'un polyester que l'on prépare en utilisant, comme catalyseur de polymérisation, de 30 à 150 ppm en tant qu'antimoine d'un composé d'antimoine et de 5 à 60 ppm en tant que germanium d'un composé de germanium. La fibre présente les caractéristiques suivantes: la teneur en groupe carboxyle terminal ne dépasse pas 25 eq/ton, la teneur en diéthylène glycol (DEG) ne dépasse pas 1,3 % en poids, la viscosité intrinsèque (IV) est au moins égale à 0,85, la somme (S) de l'allongement intermédiaire et le retrait à la chaleur sèche est inférieure à 8 %, le produit entre la résistance et l'allongement (T E) est au moins égal à (2S + 5), et le module terminal (TM) ne dépasse pas 40 g/d. Cette fibre de polyester est utilisée comme renfort de caoutchouc.
