摘要:
Polyester fibers having both a high strength and a high modulus prepared from an 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°C. Processes for producing the fibers are also disclosed.
