ABSTRACT:
Fine polyethylene terephthalate fiber having a monofilament denier of not more than about 4 deniers is spun at a high spinning speed of not less than 7,000 m/min, the polyethylene terephthalate filaments extruded from a spinneret having a plurality of spinning holes being passed through a heating zone provided beneath the spinneret and then being bundled by a bundling guide positioned beneath the point of completion of filament fining, which point exists within or below the heating zone. The obtained fiber has a highly improved dyeability.
