Abstract: A drawn yarn having a durable mechanical and thermal stability in practical use is produced from a fiber-forming polymer by means of a single continuous process. A yarn(Y) extruded from a spinneret (1) is first introduced into a liquid bath (2) for cooling and subsequently to a hot chamber (6) filled with pressurized steam (13) for heat-treatment, in which the yarn (Y) is drawn against a resistance caused by the liquid bath (2). The vessel (3) for the liquid bath (2) is provided with a yarn exit path (4) adapted to allow the passage of the yarn (Y) but inhibit the leakage of the liquid (2) and to remove concomitant liquid from the yarn. The hot chamber (6) is provided with inlet and outlet paths (7,7') for the yarn(Y) also adapted to allow the passage of the yarn but inhibit the leakage of the steam (13). The system is suitable for producing for industrial use a yarn composed of thicker individual filaments.

Abstract: A process and an apparatus for simultaneously drawing and false-twisting a thermoplastic synthetic yarn, in or by which an undrawn or a partially drawn yarn is drawn under a dry hot condition in false-twisted condition of the yarn derived by twist transmitted from a false-twister, and immediately thereafter is heat-set under a wet hot condition prior to untwisting.The apparatus includes a yarn heater, which comprises a dry heater (3') disposed on the side of a feeding device (2) for the undrawn or partially drawn yarn, and a wet heater (3") disposed on the side of a false-twister (5) along the yarn running direction.By the process and apparatus, it is possible to sufficiently heat the yarn in a short heat-treating distance, without permitting to take place a substantial increase of external leakage of steam from the heater and a reduction of the mechanical strength of a textured yarn.

Abstract: This invention relates to a method and an apparatus for producing a polyester fiber involving the steps of cooling a plurality of polyester fibers melt-spun from a spinneret (2) to a temperature below a glass transition point, taking up the fibers at a take-up speed of less than 4,000 m/min by a non-heated first godet roller (7), heat-stretching the fibers in a normal-pressure steam atmosphere at a temperature above a glass transition point of the polyester fiber (first heat-treating apparatus (8)) between the first non-heated godet roller (7) and a second non-heated godet roller (10), and heat-treating the fiber in a pressurization steam atmosphere at above 105 DEG C (second heat-treating apparatus (9)).

Abstract: PURPOSE: To provide a cooler for melt-spinning synthetic fiber where a cooling tube having the exhaustion part at its bottom is connected to the lower part of the ejector to promote the heat exchange between the cooling air and the melt-spun fiber yarn and attain satisfactory cooling. CONSTITUTION: The yarn 2 melt-spun from the spinneret 1 is passed through a cooling unit 10 comprising an ejector 6, a cooling tube 7 and a exhauster 8 and taken up with a godet roller 9. The cooling air fed from an inlet 6b to the ejector flows down in the cooling tube along the tube axis to sufficiently effect heat exchange with the yarn 2 and exhausted from an outlet 8b.

Abstract: PURPOSE:To provide a method for producing thick denier polyester filaments not having dyeing irregularity, having sufficient mechanical properties and a sufficient thermal shrinkage constant and good in tension and stiffness at a low cost. CONSTITUTION:This method for spinning and drawing thick denier polyester filaments having a single filament fineness of >=3.5 denier comprises extruding a melted polyester from a spinneret 1, cooling and so solidifying the extruded filaments, imparting water to the filaments in an amount of >=3% per weight of the filaments, taking up the filaments with a non-heated first godet roller 5 at a take-up rate of 2000-4000m/min without winding up the filaments, heating and drawing the filaments with a first thermally treating device 6 having a steam atmosphere of atmospheric pressure and set between the first godet roller 5 and a non-heated second godet roller 7, thermally treating the drawn filaments with a second thermal treating device 8, and subsequently winding up the filaments.
