摘要： A method of producing a multifilament yarn from a thermoplastic polymer includes the steps of producing a majority of fluid filaments by melt-extrusion, cooling the fluid filaments to at least partly harden at a point of consolidation, guiding the hardened filaments by a yarn guiding element, sensing the tension of the hardened filaments, varying the distance between the yarn guiding element and the point of consolidation by moving the yarn guiding element in a vertical direction in response to the sensed tension, and combining the majority of hardened filaments to form at least one multifilament yarn. An apparatus for producing a multifilament yarn from a thermoplastic polymer includes a yarn guiding element being movable in a vertical direction. A drive serves to change the vertical position of the yarn guiding element with respect to a point of consolidation of the filaments. At least one sensor senses the yarn tension of the filaments. A control unit serves to control the drive in response to the sensed yarn tension to change the vertical position of the yarn guiding element.

摘要： A melt spinning apparatus that prevents filaments passing through an unstable area from contacting one another. In a melt spinning method for thinning and solidifying each molten filament F ejected from a plurality of nozzles to obtain a yarn Y comprising a plurality of filaments F, each filament F being thinned is charged to the same polarity, and when the plurality of filaments F are assembled together, charge is eliminated from them. In a melt spinning apparatus 11 having an unstable area A generated necessarily during the rapid thinning of each filament F between a spinning pack 2a of an ejecting device 2 located above and a filament converging portion B located below, a charging device 12 is provided that charges each filament F to the same polarity between the spinning pack 2a and an inlet Aa of the unstable area A; also, a static eliminating device 13 is provided that eliminates charge from each filament F between an outlet Ab of the unstable area A and the filament converging portion B.
