Abstract: PURPOSE:To obtain yarn having high strength by one process, by extruding a polymer from a spinneret into a pressurized atmosphere, cooling and solidifying the extruded polymer in it once, drawing it under heating, pulling it from a sealing part into an atmosphere at normal pressure. CONSTITUTION:A thermoplastic polymer capable of being subjected to melt spinning is extruded in a molten state from the spinneret 7 into the column S of pressurized atmosphere set directly under it, cooled and solidified by the heat exchanger part Sa at the top of the column S, drawn under heating by the heating zone 35 set at the middle part of the column S, pulled out from the seling part 24 set at the bottom part of the column S, sent through the godet rollers 30a and 30b, and wound round the winder 33. Favorably the pressure of the column S is >=1kg/cm , preferably >=3kg/cm higher than normal pressure.

Abstract: PURPOSE:To obtain the titled fibers having high strength and good uniformity, by melt extruding a thermoplastic polyester polymer through a spinneret, cooling the extruded filaments to the glass transition temperature or below, and hot drawing the cooled filaments in a heating zone where a heated gas passed through a wire net and rectified is passed. CONSTITUTION:A thermoplastic polyester polymer, e.g. polyethylene terephthalate, is melt extruded through a spinneret, and the resultant filaments (Y) are cooled once to the glass transition temperature or, below passed further through a heated zone, e.g. a heated cylinder 1, and hot drawn in the heated zone. In the process, a heated gas at 10-80Nl/min flow rate is supplied from a heated gas supply part 3 and introduced into the heated zone while passed through a wire net 4 of 20 mesh or above and rectified, and the filament yarn is taken off at >=3,000m/min taking off speed to give the aimed fibers.
