Abstract
PURPOSE: Undrawn yarns that are produced by effecting melt-spinning at a specific spinning speed are drawn with hot feed rolls or a hot pin whose temperature is controlled in a specified range to produce the titled fibers without application of complicated spinning and drawing conditions, moreover with no yarn break.
CONSTITUTION: A polymer of substantially polybutylene terephthalate, that is, consisting of more than 85mol% of butylene terephthalate as a structure unit, is melt spun at 1,100W1,800m/min to give undrawn yarns. The drawing of the undrawn yarns is effected with hot feed rolls or hot pin in the drawing zone where the temperature T(°C) satisfies the equation [T0 is a temperature at which the heat-shrinkage stress becomes 0, when it is measured under the conditions where the yarn is loaded with a weight of 1/10 denier and the tomperature-rising rate is 2.5°C/sec] and T≤110 to produce the objective fibers.
