Die Erfindung betrifft eine Verbundstoffbahn aus mindestens drei, durch Schweißstellen miteinander verbundenen Schichten. Unter Schichten sind Bahnen von Folien, Schaumstoffen oder textlien Flächengebilden wie Gewebe, Gewirke, Geflechte oder Vliesstoffe zu verstehen. Sie sind durch Verschweißen,also durch stellenweise Verklebung benachbarter Schichten infolge eines zeitweiligen Einflusses von Wärme und evtl. auch von Druck,miteinander verbunden.The invention relates to a composite web of at least three layers connected to one another by welding points. Layers are sheets of foils, foams or flat textiles such as woven, knitted, braided or woven fabrics Understanding nonwovens. They are caused by welding, i.e. by gluing adjacent layers in places a temporary influence of heat and possibly also pressure.

Gebraucht werden solche Verbundstoffbahnen, wenn der textile Charakter im Sinne von DIN 60 000 (Januar 1969) überwiegt, hauptsächlich für Bekleidungszwecke. Sie dienen dann der Verbesserung des Komforts, und zwar vor allem unter dem Gesichtspunkt der Hygiene, indem sie aufgrund ihrer porösen lufteinschließenden Struktur hauptsächlich gegen Kälte schützen.Such composite webs are used if the textile character in the sense of DIN 60 000 (January 1969) predominates, mainly for clothing purposes. They then serve to improve comfort, especially from the point of view hygiene by mainly protecting against cold due to their porous air-enclosing structure.

Eine derartige textile Verbundstoffbahn aus mehreren durch Schweißstellen miteinander verbundenen Schichten ist in dem deutschen Gebrauchsmuster mit dem Aktenzeichen G 81 28 386.5 beschrieben. Dabei wurden alle Schichten durchgehend von der einen zu der anderen Seite der Bahn an der Schweißstelle erwärmt, bis die thermoplastischen Polymeren genug klebrig geworden sind, und dann zusammengedrückt. Dadurch verlor die Verbundstoffbahn an dieser Stelle ihre vorteilhafte poröse, lufteinschließende Struktur vollständig. Sie wird praktisch kompakt; ihre Dicke wird um mindestens die Hälfte reduziert. Damit verschlechtert sich drastisch ihre Isolationsfähigkeit. Es entstehen sogenannte "Kältebrücken". Ein weiterer Nachteil der durchgehenden Schweißnaht ist, daß sie den Griff deutlich verhärtet.Such a textile composite web of several layers connected to one another by welds is in the German utility model with the file number G 81 28 386.5. In doing so, all layers were consistently supported by the one is heated to the other side of the web at the weld point until the thermoplastic polymer has become tacky enough are, and then squeezed. As a result, the Composite web at this point its advantageous porous, air-enclosing structure completely. It becomes practical compact; their thickness is reduced by at least half. This drastically deteriorates their insulation ability. So-called "cold bridges" arise. Another disadvantage of the continuous weld is that it clearly feels the grip hardened.

Trotz dieser Nachteile ist man - aufgrund der prinzipiellen Vorteile des Verschweißens wie zum Beispiel Sauberkeit, Schnelligkeit und keine zusätzlichen Hilfsstoffe - an einer Ausweitung seiner Anwendung interessiert. Hinderlich dabei ist unter anderem, daß mit zunehmender Dicke der Schichten bei einigen Schweißverfahren Schwierigkeiten auftreten, zum Beispiel beim Wärmeimpulsverfahren. Denn hierbei werden die zu verschmelzenden Thermoplasten von außen her erwärmt. Dabei eine optimale Verteilung der Wärme über die ganze Schweißstelle zu erreichen, wird umso schwieriger, je dicker der thermoplastische Stoff ist, zumal er meistens ein schlechter Wärmeleiter ist.Despite these disadvantages, one is - due to the basic advantages of welding, such as cleanliness, Speed and no additional auxiliary materials - interested in expanding its application. A hindrance is, inter alia, that with increasing thickness of the layers difficulties arise in some welding processes for Example with the heat pulse method. Because here the to be fused thermoplastics heated from the outside. Thereby an optimal distribution of the heat over the whole welding point The thicker the thermoplastic material, the more difficult it is to achieve, especially since it is usually a poor conductor of heat is.

Demgemäß besteht die Erfindungsaufgabe darin, die bekannten Verbundstoffbahnen mit ihren von der einen zur anderen Seite durchgehenden, jeweils alle Schichten erfassenden Schweißstellen hinsichtlich ihrer Isolierung und ihres GriffesAccordingly, the object of the invention consists in the known Composite sheets with theirs from one side to the other continuous welds covering all layers with regard to their insulation and their grip

zu verbessern. Darüberhinaus soll eine Möglichkeit aufgezeigt werden, wie auch dicke Schichten mit verringerten Schwierigkeiten bezüglich der Wärmeleitung miteinander verschweißt werden können.to improve. In addition, a possibility is to be shown, as well as thick layers with reduced difficulties can be welded to one another with regard to heat conduction.

Diese Aufgaben werden durch die in den Patentansprüchen angegebene Erfindung gelöst. Sie besteht hauptsächlich darin, daß die Schweißstellen jeweils nicht alle Schichten miteinander verbinden. Besteht also zum Beispiel ein Verbundstoff aus drei Schichten, so verbinden nicht alle Schweißstellen jeweils alle drei Schichten, sondern ein Teil der Schweißstellen verbindet die Mittelschicht nur mit der einen Außenschicht und der andere Teil verbindet sie nur mit der anderen Außenschicht.These objects are given by the claims Invention solved. It consists mainly in the fact that the welds do not each have all layers together associate. So if, for example, a composite consists of three layers, not all welds connect every three layers, but some of the welds only connect the middle layer to one Outer layer and the other part only connects them to the other outer layer.

Vorteilhafte Ausführungsarten der Erfindung gemäß Anspruch werden in den Unteransprüchen 2 bis 6 beschrieben. Die Erfindung wirkt sich besonders vorteilhaft aus, wenn der Verbundstoff nur textile Flächengebilde enthält, da hierbei eine durchgehende Schweißstelle besonders nachteilig ist, verglichen mit einem Verbundstoff, der z.B. nur Folien enthält. Von besonderer Bedeutung sind aber auch Verbundstoffe aus textlien und nichttextilen Flächengebilden, wie z.B. Folien, wenn der textile Charakter überwiegt, d.h. die textile Materialbeschaffenheit der Oberfläche und/oder die für den textlien Anteil typischen physikalisch-technologischen Eigenschaften entscheidend sind für den Verbundstoff. Die nichttextile Schicht,ζ.B. eine Folie, übt nur eine zusätzliche Funktion aus; sie macht den Verbundstoff z.B. undurchlässig für Wind und Wasser oder bietet Schutz gegen Entflammung und Hitze. Der textile Charakter des Verbundstoffes bleibt vor allem dann erhalten, wenn nicht-textile Schichten von geringer Dicke und hoher Geschmeidigkeit mitverwendet werden.Advantageous embodiments of the invention according to claim are described in subclaims 2 to 6. The invention has a particularly advantageous effect if the composite material only contains flat textile structures, since this is a continuous one Welding point is particularly disadvantageous compared to a composite material that contains only foils, for example. Really important But there are also composites made of textiles and non-textile fabrics, such as foils, if the textile Character predominates, i.e. the textile material properties of the surface and / or that which is typical for the textile part Physico-technological properties are decisive for the composite. The non-textile layer, ζ.B. a slide, only has an additional function; it makes the composite material impermeable to wind and water or offers protection against inflammation and heat. The textile character of the composite is retained especially when it is non-textile Layers of low thickness and high suppleness can also be used.

Mit der Ausgestaltung nach Anspruch 3 wird vor allem eine erhöhte Bindefestigkeit zwischen den einzelnen Schichten erzielt. Das bindende Polymere kann auf unterschiedliche Art in den Schichten verteilt sein; z.B. es kann darin als Mantel-Komponente einer Bikomponentenfaser des Kern-/Mantel-Typs oder als Faser in einer Fasermischung enthalten sein.With the embodiment according to claim 3, an increased bond strength between the individual layers is achieved in particular. The binding polymer can be distributed in the layers in different ways; E.g. it can be used in it as a jacket component a bicomponent fiber of the core / sheath type or as a fiber in a fiber blend.

Besonders vorteilhaft ist es, wenn Schichten zwei verschiedene Polymere mit unterschiedlichen Schmelzbereichen enthalten, z.B. Polyamid 6 und Polyamid 6.6. Dadurch wird vor allem sowohl eine gute Verklebung durch die Komponente mit dem niedrigeren Schmelzbereich als auch eine weitgehende Erhaltung der Faserstruktur der höherschmelzenden Komponente erreicht.It is particularly advantageous if layers contain two different polymers with different melting ranges, e.g. polyamide 6 and polyamide 6.6. This ensures above all a good bond through the component with the lower melting range as well as an extensive retention of the fiber structure of the higher melting component is achieved.

Es gibt mehrere Möglichkeiten, die beanspruchte Verbundstoffbahn herzustellen. Das erfindungsgemäße Verfahren besteht j darin, daß das Schweißwerkzeug nicht jeweils auf alle Schichten einwirkt. Von zum Beispiel insgesamt vier Schichten werden an einer zu verschweißenden Stelle die zwei Mittelschichten nur mit der einen Außenschicht durch das Heizelement erwärmt und dann mit dem erforderlichen Druck miteinander verbunden. An einer anderen Stelle werden dann die Mittelschichten nur mit der anderen Außenschicht verschweißt.There are several ways of producing the claimed composite web. The method according to the invention exists j in that the welding tool does not act on all layers. For example, a total of four shifts will be on At a point to be welded, the two middle layers are only heated with the one outer layer by the heating element and then connected to each other with the required pressure. At another point then the middle classes are just with welded to the other outer layer.

Dieses Verfahren wird erfindungsgemäß dadurch ermöglicht, daß die Schichten vom Einlauf der Bahnen in die an sich bekannte Vorrichtung zur Herstellung bekannter geschweißter Verbundstoffe bis zum Schweißwerkzeug durch zwei Vorrichtungselemente auseinandergehalten werden, wobei die Elemente kammartig gestaltet sind und die Längsachsen ihrer Zähne parallel angeordnet/ aber seitlich gegeneinander verschoben sind. Wird eine Bahn oberhalb dieser Elemente in die Vorrichtung eingeführt, dann verhindern die kammartigen Elemente, daß sich alleAccording to the invention, this method is made possible by that the layers from the entry of the webs in the known device for the production of known welded Composites to the welding tool through two fixture elements be kept apart, the elements are designed like a comb and the longitudinal axes of their teeth parallel arranged / but shifted laterally against each other. If a web is fed into the device above these elements, then the comb-like elements prevent all of them

drei Schichten berühren. Die Zähne der Elemente erlauben nur den direkten Kontakt von zwei Bahnen an einer bestimmten Stelle. Die dritte Bahn wird durch sie ferngehalten,bis das Schweißwerkzeug passiert ist. Bevorzugt werden die Elemente seitlich soweit gegeneinander verschoben, daß die Zähne des einen Elementes die Zwischenräume zwischen den Zähnen des anderen Elementes voll überdecken.touch three layers. The teeth of the elements only allow direct contact between two tracks at a certain point. The third web is kept away by it until the welding tool has happened. Preferably, the elements are laterally shifted against each other that the teeth of one Element completely cover the spaces between the teeth of the other element.

Die Erfindung wird im folgenden anhand schematischer Zeichnungen näher erläutert:The invention is explained in more detail below with reference to schematic drawings:

In Figur 1 soll der prinzipielle Aufbau des erfindungsgemäßen Verbundstoffes durch eine Schnittansicht der Quer- und Längsseite dargestellt werden. Der Verbundstoff besteht aus insgesamt drei Schichten, einer oberen Schicht I7 einer mittleren Schicht 2 und einer unteren Schicht 3. In der Schweißnaht 4 sind die Schichten 1 und 2 miteinander verklebt, während die Schicht 3 an dieser Stelle nicht verklebt ist. In der Schweißnaht 5 sind die Schichten 2 und 3 miteinander verbunden. Die Schicht 1 liegt an dieser Stelle ungebunden darüber.In Figure 1, the basic structure of the composite material according to the invention is to be shown by a sectional view of the transverse and longitudinal side. The composite consists of a total of three layers, an upper layer I 7, a middle layer 2 and a lower layer 3. In the weld 4, the layers 1 and 2 are glued together, while the layer 3 is not glued at this point. In the weld 5, the layers 2 and 3 are connected to one another. Layer 1 is unbound at this point.

In Figur 2 soll das erfindungsgemäße Herstellungsverfahren dargestellt werden. Sie zeigt eine Schnittansicht durch die erfindungsgemäßen kairor.artigen Vorrichtungs-Elemente 5 und 6 in Fahrtrichtung.

der Schweißnähte ergibt sich im wesentlichen aus dem Abstand der Zähne des kammartigen Elementes.of the weld seams results essentially from the distance between the teeth of the comb-like element.

Selbstverständlich können anstelle der Schichten 1/ 2 und jeweils mehrere Schichten eingesetzt werden/ z.B. jeweils zwei Schichten oben, drei Schichten in der Mitte und eine Schicht unten.Of course, instead of layers 1/2 and Several layers are used in each case / e.g. two layers on top, three layers in the middle and one Layer down.

Bei der Herstellung des erfindungsgemäßen Verbundstoffes können die bisherigen Erfahrungen insbesondere bezüglich der Ausgangsstoffe (z.B. Art, Anzahl, Reihenfolge und Dicke der Schichten; Art der eingesetzten Polymere und der Zusätze) voll genutzt werden. Auch die Schweiß-Verfahren sind im wesentlichen unverändert.In the production of the composite according to the invention the previous experience, especially with regard to the starting materials (e.g. type, number, sequence and Thickness of the layers; Type of polymers used and additives) can be used to the full. Even the welding process are essentially unchanged.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß im Verbundstoff keine durchgehenden Schweißstellen vorhanden sind und damit keine Kältebrücken. Der Griff wird weniger stark verhärtet, da die Schweißnähte weniger dick sind. Das Herstellungsverfahren erlaubt die Verwendung auch dicker Schichten, da ja jeweils nur ein Teil aller Schichten verschweißt wird und dementsprechend die Wärme nur durch einen Teil der Schichten geleitet werden muß. Die erfindungsgemäßen Verbundstoffe eignen sich aufgrund ihrer Vorteile insbesondere zur Herstellung von Bekleidung. Bevorzugte Einsatzgebiete sind: Sport-Bekleidung, Winter-Bekleidung, Morgenröcke, Regenmantel, Windeln und Matratzenüberzüge.The advantages achieved by the invention are in particular that there are no continuous in the composite There are welds and therefore no cold bridges. The handle is hardened less because of the welds are less thick. The manufacturing process also allows thick layers to be used, since only part of all layers is welded and accordingly the heat is only conducted through part of the layers must become. The composite materials according to the invention are particularly suitable for production because of their advantages of clothing. Preferred areas of application are: sports clothing, winter clothing, dressing gowns, raincoats, Diapers and mattress covers.
