Polyester fibers having both a high strength and a high modulus prepared from ethylene terephthalate polyester, and having an intrinsic viscosity of not less than 1.0 and an initial tensile modulus is not less than 130 g/d, said intrinsic viscosity being determined in a mixed solvent of p-chlorophenol and tetrachloro ethane (3:1) at 30.degree. C. Processes for producing the fibers are also disclosed.
