Abstract

The supply channels lie in a plane at right angles to that of the clothes hanger-shaped distribution channel. They join into the feed channel. The nozzle head is implemented for melt-blowing of fibers. Air-blasting channels are located on either side of the nozzle bores. These supply flat hot air jets (curtain jets) below the nozzles, orientated at acute angles with respect to each other.

Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Mehrkomponentenfäden aus unterschiedlichen Kunststoffen, insbes. für ein Vlies, bestehend aus einem Breitschlitzwerkzeug mit Zufuhrkanälen für die Kunststoffschmelzen und mit einem einem Speisungskanal nachfolgenden Kleiderbügelverteilerkanal und aus einem dem Austrittsspalt des Kleiderbügelverteilerkanals nachgeschalteten Düsenkopf mit einer Vielzahl von Düsenbohrungen, die in einer längs des Austrittsspaltes verlaufenden Reihe angeordnet sind.The invention relates to a device for producing Multi-component threads made of different plastics, esp. for a fleece, consisting of a wide slot tool with feed channels for the plastic melts and with one following a feed channel Hanger distribution channel and from an exit gap the nozzle head downstream of the hanger distribution channel with a variety of nozzle bores that run in a longitudinal of the outlet gap extending row are arranged.

Bei bekannten Vorrichtungen der genannten Art (DE-A-197 50 723) ist die Anordnung regelmäßig so getroffen, daß die Kunststoffschmelzen erst kurz vor den Düsenbohrungen zusammengeführt werden, um Vermischungen zu verhindern. Das ist in konstruktiver Hinsicht sehr aufwendig, weil für jede der Kunststoffschmelzen ein getrennter Kleiderbügelverteilerkanal - der diesen Namen aufgrund seiner Form trägt - erforderlich ist und im Anschluß daran unzählige Bohrungen aufweisende Verteilerplatten für die individuelle Zuführung der Kunststoffschmelzen zu den einzelnen Düsenbohrungen vorgesehen sind. Der Düsenkopf ist als Spinndüsenkopf mit mehreren parallelen Düsenbohrungsreihen ausgebildet. Hiermit können zwar zu gleicher Zeit viele Fäden hergestellt werden, diese weisen aber einen verhältnismäßig großen Durchmesser auf, was einer anschließenden Legung feinfädiger Vliese entgegensteht. Sollen die Mehrkomponentenfäden auch noch gekräuselt werden, ist zudem eine sehr energieintensive Nachbehandlung mit Heißluft erforderlich. In known devices of the type mentioned (DE-A-197 50 723) the arrangement is regularly made so that the plastic melts just before the nozzle holes be brought together to prevent mixing. The is very complex in terms of construction, because for everyone the plastic melts a separate hanger distribution channel - of this name because of its shape carries - is necessary and afterwards countless Distribution plates with holes for the individual Feeding the plastic melts to the individual Nozzle holes are provided. The nozzle head is as Spinneret head with several parallel rows of nozzle bores educated. Many can do this at the same time Threads are made, but they have one relatively large diameter on what one subsequent laying of fine-thread nonwovens. Should the multi-component threads also be crimped is also a very energy-intensive after-treatment with hot air required.

Zur Herstellung von feinen Kunststoffäden ist es zwar auch schon bekannt (DE-C-40 36 734), das sogenannte Meltblownverfahren einzusetzen, bei dem der Düsenkopf als Meltblowndüsenkopf mit beidseits einer Reihe von Düsenbohrungen vorgesehenen Blasluftzuführungseinrichtungen zum Zuführen von unterhalb der Düsenbohrungen spitzwinklig gegeneinander geführten Heißluftflächenstrahlen ausgebildet ist, durch die die Fäden zu verhältnismäßig kleinen Durchmessern heruntergezogen werden. Für die Herstellung von Mehrkomponentenfäden sind diese Maßnahmen bisher nicht in Betracht gezogen worden.It is also for the production of fine plastic threads already known (DE-C-40 36 734), the so-called meltblown process use where the nozzle head as Meltblow nozzle head with a row of on both sides Blower air supply devices provided nozzle holes for feeding from below the nozzle bores at an acute angle against each other directed hot air surface jets is through which the threads become relatively small Diameters are pulled down. For the production So far, these measures are not of multi-component threads have been considered.

Der Erfindung liegt das technische Problem zugrunde, mit einer konstruktiv einfachen Vorrichtung der eingangs genannten Art Mehrkomponentenfäden hoher Feinheit herzustellen.The invention is based on the technical problem with a structurally simple device at the beginning mentioned type to produce multi-component threads of high fineness.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß die Zufuhrkanäle in einer zur Ebene des Kleiderbügelverteilerkanals senkrechten Ebene in den Speisungskanal zusammengeführt sind und daß der Düsenkopf als Meltblowndüsenkopf mit beidseits der Reihe der Düsenbohrungen vorgesehenen Blasluftzuführungseinrichtungen zum Zuführen von unterhalb der Düsenbohrungen spitzwinklig gegeneinander geführten Heißluftflächenstrahlen ausgeführt ist.The solution to this problem according to the invention consists in that the feed channels in a to the level of Hanger distribution channel in the vertical plane Feed channel are merged and that the nozzle head as a meltblow nozzle head on both sides of the row Blower air supply devices provided nozzle holes for feeding from below the nozzle bores at an acute angle hot air surface jets directed against each other is.

Die Erfindung geht hierbei zunächst von der Erkenntnis aus, daß auch Mehrkomponentenfäden hoher Feinheit nach dem Meltblownverfahren hergestellt werden können. Führt man dabei die Kunststoffschmelzen bereits am Eingang des Breitschlitzwerkzeuges gleichsam in mehreren Schichten nebeneinander, so treten überraschenderweise auf dem gemeinsamen Wege durch den Kleiderbügelverteilerkanal bis zu den Düsenbohrungen praktisch keine Vermischungen der Kunststoffschmelzen auf, so daß auf aufwendige Verteilerplatten vollständig verzichtet werden kann. Handelt es sich bei den Kunststoffen um solche mit stark unterschiedlichem Dehnungs- bzw. Schrumpfungsverhalten für erhöhte Krimpeigenschaften, kann sogar auf eine energieintensive Nacherwärmung verzichtet werden, weil deren Aufgabe automatisch von den Heißluftflächenstrahlen übernommen wird. In gleicher Weise können die Heißluftflächenstrahlen auch zum Spleißen der Mehrkomponentenfäden eingesetzt werden, um eine noch größere Feinheit (bis 1 µm) zu erreichen.The invention starts from the knowledge that that even multi-component threads of high fineness after Meltblown processes can be produced. One leads the plastic melts already at the entrance of the Wide slot tool in several layers, as it were side by side, so surprisingly occur on the common paths through the hanger distribution channel practically no mixing of the nozzle bores Plastic melts on, so that on expensive Distribution plates can be completely dispensed with. Are the plastics strong? different expansion or shrinkage behavior for increased crimp properties, can even on a energy-intensive reheating can be dispensed with because their task automatically from the hot air surface jets is taken over. In the same way, the Hot air blasting also for splicing the multi-component threads used to make an even bigger one To achieve fineness (up to 1 µm).

Nach bevorzugter Ausführungsform sind die Zufuhrkanäle mit Einstellorganen für die Zufuhrrate der jeweiligen Kunststoffschmelze versehen. Im übrigen ist es für eine hohe Produktionsgeschwindigkeit günstig, wenn im Übergangsbereich vom Kleiderbügelverteilerkanal zum Meltblowndüsenkopf eine sich über die gesamte Kopflänge erstreckende, zur Ebene des Kleiderbügelverteilerkanals erstreckende Kanalverbreiterung vorgesehen ist.According to a preferred embodiment, the supply channels are included Adjustment elements for the feed rate of the respective Plastic melt provided. For the rest, it is for one high production speed cheap if in Transition area from the hanger distribution channel to Meltblow nozzle head over the entire length of the head extending to the level of the hanger distribution channel extending channel widening is provided.
