Definitions

  • the invention relates to a method for melt spinning a multifilament String of threads from a polymer melt according to the preamble of claim 1.
  • the coulter becomes a Forms a variety of filaments that are extruded through die holes.
  • the coulter is pulled out of the spinning zone by a pulling agent. After the filaments of the thread sheet emerge from the nozzle bores are cooled in a cooling zone until the yarn sheet solidifies of filaments.
  • blowing is preferred used, as are known for example from DE 35 03 818. Doing so in a cooling shaft below the nozzle holes a coolant in the essentially blown radially against the thread sheet. Immediately below the A cooling shaft is formed in the cooling shaft.
  • the stretching shaft has one venturi-like deformation to one to stretch the thread sheet to generate accelerated air flow.
  • the stretching shaft is on one Vacuum source connected. In this process, the thread group cooled intensively so that the pulling force generated by the stretching does not leads to the tearing of the filaments.
  • the thread sheet In the case in which the thread sheet consists of a ring-shaped arrangement Row of nozzle bores is spun, the thread sheet is cooled also by a radially directed coolant flow, such as from EP 0 536 497 is known.
  • the filament cluster is immediately after Exit from the nozzle bores with a radial from the inside out directed cooling air flow cooled.
  • the thread sheet In the known methods, the thread sheet is cooled intensively inside the cooling zone. This gives the filaments of the thread group one crystalline pre-orientation, which the subsequent stretching and thus the determine the physical properties of the thread group.
  • An increase in Production speed in the known method thus leads inevitably changes in physical properties or insufficient cooling to filament breaks.
  • WO 00/05439 and WO 99/67450 describe a spinning device for spinning a synthetic thread, which by combining one of a plurality of individual Filaments existing filament bundle is formed.
  • WO 95/15409 describes a melt spinning process and a device for melt spinning with a cooling zone for cooling the melt at which the speed of the air flow is the surface speed of the thread is adjusted so that between the thread and the adjacent Insignificant frictional forces arise in the air layer.
  • the object is achieved by a method with the features according to claim 1 solved.
  • the invention is based on the knowledge that the solidification of the filaments the coulter of threads from the exit from the nozzle bores to solidification two mutually influencing effects is determined. It is known that when a polymer melt cools down, it starts to melt from a certain point Solidified temperature. This process depends solely on the temperature and is referred to here as thermal crystallization. When melt spinning a set of threads pulls the set of threads out of the spinneret. there pulling forces act on the filaments of the thread sheet, one cause tension-induced crystallization in the filaments. At the Melt spinning a sheet of threads thus undergo thermal crystallization and the stress-induced crystallization overlays and leads together to Solidification of the filaments.
  • the invention now provides a method in which the Filaments of the thread family are cooled in such a way that both effects Achieve higher production speeds with the same good ones physical properties can be influenced.
  • the filaments of the Thread group initially in the cooling zone, which is referred to here as the pre-cooling zone, pre-cooled without solidification of the polymer melt.
  • the Thread coulter directly into a below the pre-cooling zone and in front of a pull-off agent trained second cooling zone, which is referred to here as a post-cooling zone.
  • the filaments of the thread group are placed under the post-cooling zone Exposure to a cooling medium flow directed in the thread course until solidification cooled further, the cooling medium flow being a predetermined one Has flow rate to influence the thread friction.
  • the withdrawal tension acting on the filaments can be influenced in such a way that the voltage-induced crystallization takes place with a delay. Because the filaments the thread sheet in the pre-cooling zone essentially only in the peripheral zones are solidified, no significant withdrawal voltages from the Filaments are recorded. This means that none occurs in the pre-cooling zone essential stress-induced crystallization but only one thermally induced crystallization.
  • the thread group can be in one linear row arrangement or in a circular row arrangement spin out of the nozzle holes of several or one spinneret.
  • the cooling medium flow to influence the thread friction in an acceleration section within the post-cooling zone accelerated to the predetermined flow rate.
  • the acceleration path is preferably immediately before Solidification area of the filaments of the thread sheet is formed. So that the Post-cooling in the post-cooling zone regardless of the pre-cooling in the Influence and control the pre-cooling zone. Secondly, it is guaranteed that the accelerated cooling medium flow in one phase on the filaments of the thread family in which the filaments attack an external air friction endured without breaking the filaments.
  • the flow rate of the Coolant flow before the solidification area of the filaments at least the same or slightly higher than the running speed of the filaments.
  • the Flow rate of the cooling medium flow differs from that Filament speed preferably by a factor of 0.3 to 2.
  • the particularly advantageous method variant according to claim 4 is in particular suitable for threads with small, medium or large thread titers with higher Production speed and uniform physical properties manufacture.
  • the influencing of the voltage-induced Crystallization under essentially constant conditions performed.
  • Pre-cooling of the filaments of the thread sheet after exiting the cooling effect of the nozzle bores within the cooling zone is such adjustable that the position of the solidification area of the filaments of the thread sheet be kept within a predetermined target range within the post-cooling zone can.
  • the filaments of the thread sheet solidify in the post-cooling zone thus essentially always in the same place, so that a uniform Treatment of the filaments to influence the tension-induced Crystallization is granted.
  • the through the Cooling medium in the pre-cooling zone cooling effects can be changed be executed.

  • the cooling medium can its temperature before entering the pre-cooling zone preferably to a value be heated in the range of 20 ° C to 300 ° C.
  • a Spinning threads with relatively small filament titles becomes the cooling medium preheated to a high temperature by, for example, a heater. This is the one that starts immediately after exiting the nozzle bores thermal crystallization influenced in such a way that the filaments of the thread sheet before Entry into the post-cooling zone are not frozen.
  • Cooling medium flow possible, which solidifies the filaments of the thread sheet in leads the target area of the post-cooling zone.
  • the cooling medium is on a lower temperature set in the pre-cooling zone, so that the thermal Crystallization is so far formed before entering the after-cooling zone that the Filaments of the thread sheet have sufficient stability when the cooling medium flow is attacked exhibit.
  • a blower can be used for this purpose, for example be controllable by which the volume flow blown into the pre-cooling zone is.
  • the method according to the invention is independent of whether the cooling medium flow in the post-cooling zone by suction or by blowing is produced.
  • the process variant in which a suction flow in the After cooling zone prevails, has the advantage that the thermal crystallization in the pre-cooling zone and the stress-induced crystallization in the after-cooling zone can be influenced essentially independently of one another.
  • the process variant is to obtain adequate cooling in the post-cooling zone according to claim 10 particularly advantageous.
  • the cooling medium flow is switched off the cooling medium emerging from the pre-cooling zone and one immediately before Cooling medium supplied to the inlet of the post-cooling zone. Through that additionally supplied cooling medium is achieved that the voltage-induced Crystallization is also adjustable within wide limits and thus another Optimization of the physical properties is possible.
  • Pre-cooling of the filaments in the pre-cooling zone can also be done by an in airflow blown into the pre-cooling zone or through an air stream into the pre-cooling zone sucked in air flow.
