Abstract

PURPOSE: Fiber that is mainly composed of ethylene terephthalate units with a specific birefringence, crystal orientation function, amorphous molecule orientation, intrinsic viscosity and terminal carboxyl concentration, thus being suitably used for industrial purposes, because of its high elasticity, low shrinkage and high durability.
CONSTITUTION: The objective fiber has more than 90mol% content of ethylene terephthalate units, 170W195×10-3 optical birefringence, more than 0.93 crystal orientation function fc, less than 0.92 amorphous molecule orientation parameter, less than 145Å long period, less than 8.0% shrinkage/intrinsic viscosity ratio at 150°C and less than 25 eq/106g terminal carboxyl concentration. This polymer is obtained by effecting low-temperature polymerization and/or terminal-blocking polymerization to prepare a low polymerization-degree polymer and subjecting it to solid-phase polymerization to give, e.g., a polymer of 0.70W1.20 intrinsic viscosity and 10W15 eq/106g terminal carboxyl concentration. The polymer is melt spun at a relatively low temperature under other appropriately selected con ditions to give the objective fiber.
