Abstract
Description
Schweißfaden Die Erfindung bezieht sich auf einen Schweißfaden zur Herstellung einer nahtartigen Verbindung zwischen zwei oder mehreren Lagen Materialien, der nach Einwirkung von Wärme und Druck unter Ausschmelzen der thermoplastischen Bestandteile eine Verbindung zwischen den Materiallagen berheiführt. Welding thread The invention relates to a welding thread for Creation of a seam-like connection between two or more layers of materials, which, after the action of heat and pressure, melts out the thermoplastic Components a connection between the material layers.
Alls der DAS 1 ?8 1 ist bekannt, den Schweißfaden auo Endlosfasern oder Stapelfasern aufzubauen und einem Spinn- und Zwirnprozeß herzustellen. Außerdem ist bekannt, derartige Schweißfäden auch aus monophilen Bestandteilen aufzubauen.All of DAS 1? 8 1 is known, the welding thread made of continuous fibers or to build up staple fibers and produce them in a spinning and twisting process. aside from that it is known that such welding threads can also be built up from monophilic components.
Wenn die herzustellenden Nähte elastisch sein sollen, muß neben dem thermoplastischen Bestandteil in den Zwirnverband ein durchlaufender elastischer Bestandteil enthalten sein.If the seams to be produced are to be elastic, next to the thermoplastic component in the twisted bandage a continuous elastic Be included.
Der wirtschaftlichen Produktion solcher bekannter Schweißfäden stehen erhebliche Schwierigkeiten entgegen. Das Verschweißen von Materialien, insbesondere Textilien, mit Hilfe von Schweißfäden setzt zur Erzeugung einer ausreichenden Schweißqualität ein bestimmtes thermoplastisches Fadenvolumen voraus. Häufig reicht zur Erfüllung dieser Bedingung ein einfacher Zwirn nicht ans, weshalb man gezwungen ist, entweder die Fadendicke des thermoplastischen Fadenbestandteiles zu vergrößern oder.eine sich kreuzende Umzwirnung (Criss-Cross-Verzwirnung) eines Seelenfadens durchzufuhren. Die erforderliche Volumenvergrößerung wird dabei. durch erhebliche Kostensteigerungen erkauft, was die Wirtschaftlichkeit der Schweißfaden-Verbindung in Frage stellt.The economic production of such well-known welding threads is available encountered considerable difficulties. The welding of materials, in particular Textiles, with the help of welding threads, are used to generate a sufficient welding quality a certain thermoplastic thread volume. Often enough to fulfill This condition a simple thread does not answer, which is why one is forced to either to increase the thread thickness of the thermoplastic thread component oder.eine to carry out criss-cross twisting of a core thread. The required volume increase is thereby. due to significant cost increases bought, which calls into question the profitability of the welding thread connection.
Wenn darüberhinaus die Bedingung gestellt ist, eine elastische Schweißnaht zu erzeugen, dann stellen sich der Ausführung nach der lehre der DAS 1 238 18R erhebliche Schwierigkeiten entgefflen. Es ist dem Grunde nach schon schwierig, einen Zwirn herzustellen, dessen einer Bestandteil alls Gummi oder einem anderen elastischen Material besteht, zumal im vorliegenden Fall die zusätzliche Bedingung gestellt ist, daCt der thermoplastische Fadenbestandteil mit dicht aneinanderliegenden Windungen verzwirnt sein muß. Damit die Elastizität den Gummifadens sich für den Zwirnvorgang nicht störend auswirkt, muS man die Verzwirnung bei einer langsamen Fadengeschwindigkeit vornehmen. Einem hohen konstruktiven Aufwand steht eine viel zu geringe Leistung gegenüber.If the condition is also met, an elastic weld seam to generate, then according to the teaching of DAS 1 238 18R, the implementation is considerable Troubleshoot difficulties. Basically it is difficult to find a thread to produce one component of which is rubber or another elastic Material exists, especially since in the present case the additional condition is made is that the thermoplastic thread component with tightly spaced turns must be twisted. So that the elasticity the Rubber thread for does not interfere with the twisting process, twisting has to be done with a slow one Set the thread speed. There is a lot going on in terms of design effort too low performance compared to.
Der Erfindung liegt die Aufgabe zugrunde, einen Schweißfaden zu entwickeln, der schnell und billig herstellbar ist und dessen Volumität ohne erhebliche Fostenbelastun auf die geforderten Schweißbedingungen eingestellt werden kann. The invention is based on the object of developing a welding thread which can be produced quickly and cheaply and its volume without significant post loads can be adjusted to the required welding conditions.
Diese Aufgabe wird im Sinne der Erfindung durch die Anwendung eines mit Fasern, Flocken oder dgl. aus thermoplastischem Material beflockten Fadens beliebiger Beschaffenheit als Schweißfaden gelöst. This object is achieved in the context of the invention through the application of a Any thread flocked with fibers, flakes or the like made of thermoplastic material Loosened condition as welding thread.
Beflockte Fäden sind an sich bekannt (DRP 1 057 0595. Derartige Fäden werden jedoch zu einem anderen Zweck herestellt, nämlich einen pelzartigen Effekt bei den aus solchen Fäden hergestellten Gegenständen zu erzeugen. Es ist auch bekannt, thermoplastische Flocken, nämlich Polyamidflocken, zum elektrostatischen Beflocken von Fä.chenerzeugnissen zu verwenden (DA.s 1 277 193). Auch in diesem Falle erfolgt die Beflockung mit diesen Fasern nicht der thermopl.astischen Eigenschaft wegen. Flocked threads are known per se (DRP 1 057 0595. Such threads however, they are made for a different purpose, namely a fur-like effect in the objects made from such threads. It is also known thermoplastic flakes, namely polyamide flakes, for electrostatic flocking of fan products to be used (DA.s 1 277 193). Also in this case takes place flocking with these fibers is not due to the thermoplastic elastic properties.
Durch die erfindungsgernäße Anwendung wird demgegenüber ein ganz neues Problem gelöst, nämlich durch die Wahl der Flocken größe und Flockendichte das Volumen des bpfRockten Fadens so zu dimensionieren, daß solche beflockten Laden als Schweißfäden mit gewünsehter Schweißqualität eingesetzt werden können. Wenn die Schweiß naht einen dünnen Schweißfaden voraussetzt, dann kann man den Flockenträger mit staubartigen Flocken aus thermoplastischem Material beschichten. Setzt die Schweißnaht hingegen einen besonders voluminösen Schweißfaden voraus, dann wird man dementsprechend große Flocken bevorzugen. By contrast, the application according to the invention makes a whole new problem solved, namely by the choice of flake size and flake density the volume of the bpfocked thread to be dimensioned so that such flocked shutters can be used as welding threads with the desired welding quality can. If the sweat requires a thin welding thread, then you can coat the flake carrier with dust-like flakes of thermoplastic material. If, on the other hand, the weld seam requires a particularly voluminous welding thread, then you will prefer accordingly large flakes.
Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, daß der Flockenträger aus einem elastisch dehnbaren Material, z.B. Gummi, besteht. Mit einem derartig herxestellten Schweißfaden werden die Nachteile der vorbekannten Schweißfadenherstellung gänzlich vermieden. Fjfr die Beflockung ist es unerheblich, welche Beschaffenheit der Flockenträger besitzt.An advantageous embodiment of the invention is that the The flake carrier is made of an elastically stretchable material, e.g. rubber. With a Welding threads produced in this way have the disadvantages of the previously known welding thread production completely avoided. For the flocking, it is irrelevant which texture the flake carrier possesses.
Mithin kann ein Flockenträger aus Gummi in derselben billigen Weise wie ein Trager aus einem anderen Material beflockt werden. Auf diese Weise kann man elastische gesiehwei.rte Nähte mit einem geringen Kostenaufwand erzeugen, wobei sich gegenüber dem Stand der Technik eine zusätzliche Verbilligunr dadurch ergibt, daß die verwendeten Flocken praktisch aus Abfall hergestellt und verarbeitet werden können.Thus, a flock carrier made of rubber can be used in the same inexpensive manner flocked like a carrier made of a different material. That way you can one can produce elastic gesiehwei.rte seams at a low cost, with Compared to the state of the art, this results in an additional reduction in price, that the flakes used are practically made from waste and processed can.
Im Rahmen von Ausgestaltungen der Erfindung kann man den Flockenträger beispielsweise aus Gummi, Naturkautschuk, Naturlatew, synthetischen Elastomersn herstellen, wenn man auf Nachgiebigkeit des Schweißfadens Wert legt. Kommt es auf diese Elastizität nicht an, dann kann ein Trägerfaden beliebiger Beschaffenheit verwendet werden. Als Beflockung eignen sich Flocken, Fasern, Staub oder dgl. aus zum Beispiel Polypropylen, Polyäthylen, Polyamid, Polyvynylchlorid, Polyacrylnitril, Mischpolymerisaten und dgl. Im besonderen empfiehlt es sich, solche Materialien zu verwenden, deren Flocken bei ca. 120 - 2400 C schmelzbar sind.In the context of embodiments of the invention, the flock carrier can be used for example made of rubber, natural rubber, natural latew, synthetic elastomers if you value the flexibility of the welding thread. It comes up these If there is no elasticity, a carrier thread of any kind can be used will. Flakes, fibers, dust or the like, for example, are suitable as flocking Polypropylene, polyethylene, polyamide, polyvinyl chloride, polyacrylonitrile, copolymers and the like. In particular, it is recommended to use such materials, their Flakes can be melted at approx. 120 - 2400 C.
