Abstract: PCT No. PCT/JP90/01491 Sec. 371 Date Sep. 13, 1991 Sec. 102(e) Date Sep. 13, 1991 PCT Filed Nov. 15, 1990 PCT Pub. No. WO91/07529 PCT Pub. Date May 30, 1991.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 2ROOT 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.
