Abstract

1. Heat-resistant sewing thread consisting of a thread association with two or more individual threads or yarns, characterized in that the largely twist-free thread association contains components which, as a result of liquefaction by heat which is possible only once, effect permanent adhesive bonding of the thread association, if appropriate with simultaneous mechanical compression.

Description

Gegenstand der Erfindung ist ein zusammengefaßter Faden, bestehend aus 2 oder mehreren verschiedenen Materialkomponenten, die ohne oder nur mit geringer Drehungsgebung durch thermische oder/und mechanische Verbindung zusammenverbunden sind und die sich auch bei einer nachfolgenden chemischen oder/und thermischen Einwirkung nicht mehr auflösen bzw. trennen.The subject matter of the invention is a combined thread, consisting of 2 or more different material components, which are connected together with little or no twisting by thermal and / or mechanical connection and which no longer dissolve even in the event of a subsequent chemical or / and thermal action or separate.

Zur Erreichung einer festen, bleibenden Verbindung mehrerer einzelner parallelisierten (gefachten) Fadenkomponenten gleicher oder ungleicher Materialien werden diese bisher in altbekannter Weise zusammengedreht, ein Vorgang, der mit der Bezeichnung "Zwirnen" bekannt ist.In order to achieve a firm, permanent connection of several individual parallelized (fanned) thread components of the same or different materials, these have hitherto been twisted together in a well-known manner, a process known as "twisting".

Dieser Vorgang "Zwirnen", gleichgültig nach welchem bekannten Zwirnsystem ausgeführt, ist wegen der nur relativ geringen Produktionsgeschwindigkeit teuer.This "twisting" process, regardless of which known twisting system is carried out, is expensive because of the relatively low production speed.

Es wurden daher bereits verschiedene andere Verbindungsmöglichkeiten vorgeschlagen, mit denen anstelle der Zwirnung die Zusammenfassung und bleibende Verbindung mehrerer Einzelfasern oder -fäden erreicht werden kann.Various other connection options have therefore already been proposed, with which the combination and permanent connection of several individual fibers or threads can be achieved instead of twisting.

Es wurde vorgeschlagen, die einzelnen Fasern- oder Fadenkomponenten gegenseitig zu verkleben; ein Vorgang, der in der Fachsprache mit dem Begriff "Bondieren" bezeichnet wird. Es wurde ferner vorgeschlagen, die zusammengefaßten einzelnen Faser- oder Fadenteile mit Druckluft zu verwirbeln, so, daß sie sich gegenseitig verkrallen und sich damit zu einem Faden verbinden. Als weiterer Vorschlag ist bekannt geworden, die einzelnen Fäden bzw. Fasern in ihrer Materialart verschieden zu wählen und zwar so, daß ein Fadenteil für eine thermische Klebverbindung geeignet ist. Eine solche thermische Klebverbindung kann gemäß diesem Vorschlag dadurch erfolgen, daß der thermisch verklebbare bzw. verschweißbare Fadenanteil zur Herbeiführung der Klebwirkung erwärmt wird; d.h. der noch offene Fadenverband wird durch erhöhte Temperatur und ggf. gleichzeitige mechanische Pressung dadurch zusammen verbunden, daß der schmelzbare Fadenanteil flüssig oder zumindest angeteigt sich mit dem oder den anderen Fadenteilen fest verbinden und so einen zusammenverklebten Gesamtfaden bildet.It has been proposed to glue the individual fiber or thread components to one another; a process that is referred to in technical terms as "bonding". It has also been proposed to swirl the combined individual fiber or thread parts with compressed air so that they claw each other and thus combine to form a thread. As a further proposal, it has become known to select the individual threads or fibers differently in their type of material, in such a way that a thread part is suitable for a thermal adhesive connection. Such a thermal adhesive connection can be made according to this proposal by heating the thermally bondable or weldable thread portion to bring about the adhesive effect; ie the still open thread assembly is connected together by elevated temperature and, if necessary, simultaneous mechanical pressing, in that the fusible thread portion is liquid or at least pasted firmly connected to the other thread part (s) and thus forms an overall thread which is stuck together.

Solche weitgehend drehungslos zusammen verbundenen Garne und Fäden können in den verschiedensten Anwendungsbereichen verarbeitet werden. Sie zeigen gegenüber gezwirnten Fäden bzw. Zwirnen bei einer Reihe von Anwendungsfällen keine Nachteile. Wenn jedoch diese so zusammengefaßten, also weitgehend drehungslosen Fäden einer starken Reib-oder Zugbeanspruchung oder insbesondere einer hohen thermischen Beanspruchung ausgesetzt werden, sind diese gemäß den vorbeschriebenen Techniken durchgeführten Verbindungen oft nicht genügend. Eine hohe Fadenbeanspruchung erfolgt z.B. zwangsläufig beim Nähvorgang, soweit dieser mit den dafür bekannten Nähmaschinen durchgeführt wird. Beim Nähen mit Nähmaschinen wird der Faden durch die im Verlauf der Nahtbildung häufigen Wechselvorgänge in der Festigkeit stark beansprucht und durch die schnelle Stichfolge der Nadel in das Nähgut so stark erhitzt, daß Temperaturen bis zu 400°C und mehr aufkommen. Für solche erhöhten Kraft-Dehnungs- und insbesondere Temperaturbeanspruchungen sind Fäden, wie sie mit den vorstehenden, bis jetzt bekannten Verfahren hergestellt werden können, nicht oder nicht optimal geeignet.Such largely twistlessly connected yarns and threads can be processed in a wide variety of applications. They have no disadvantages compared to twisted threads or twisting in a number of applications. However, if these threads, which are summarized in this way, that is to say largely without rotation, are subjected to strong friction or tensile stress or, in particular, to high thermal stress, they are often not sufficient in accordance with the techniques described above. A high thread stress occurs e.g. inevitably during the sewing process, insofar as this is carried out with the sewing machines known for this. When sewing with sewing machines, the thread is subjected to high stresses due to the frequent changes in strength during the course of the seam formation and heated so strongly by the rapid sequence of the needle into the material that temperatures of up to 400 ° C and more arise. For such increased force-stretching and in particular temperature stresses, threads as can be produced with the above, previously known methods are not or not optimally suitable.

Gegenstand der Erfindung ist ein zusammengefaßter Faden, bestehend aus 2 oder mehreren verschiedenen Materialkomponenten, die durch thermische oder/und mechanische Verbindung so zusammenverbunden sind, daß sie ohne oder nur mit geringer Drehungsgebung einen weitgehend fest zusammenverbundenen Fadenkörper bilden, mit der Maßgabe, daß ein oder mehrere Fadenanteile in diesem Fadenverband bei einer thermischen Behandlung sich ganz oder annähernd verflüssigen und dabei den Fadenverband ggf. vermittels einer gleichzeitig mechanisch wirkendenverpressung fest zusammen verbinden mit der Sonderheit, daß der thermisch verflüssigende Fadenanteil aus einem nur einmal thermisch verflüssigbaren Material besteht.The invention relates to a summarized thread, consisting of 2 or more different material components, which are connected together by thermal and / or mechanical connection so that they form a largely firmly connected thread body without or with little rotation, with the proviso that one or several thread portions in this thread bundle liquefy completely or approximately during a thermal treatment and thereby firmly connect the thread bundle, if necessary, by means of simultaneously mechanical pressing, with the special feature that the thermally liquefying thread portion consists of a material that can only be thermally liquefied once.

Ein solcher fest zusammengefaßter, aus 2 oder mehreren Fadenkomponenten bestehender, weitgehend drehungsloser Faden kann für alle Anwendungsfälle verwendet werden. Zufolge der erfindungsgemäßen einmaligen thermischen Plastifizierbarkeit des den Fadenverband zusammenklebenden Fadenanteiles kann ein solcher Faden sowohl gefärbt wie auch vernäht werden, da die dabei zwangsläufig aufkommenden hohen Temperaturen sowohl beim Färben wie insbesondere beim Nähden den Fadenverband nicht mehr auflösen können.Such a firmly combined, largely twistless thread consisting of 2 or more thread components can be used for all applications. As a result of the unique thermal plasticizability of the thread portion gluing the thread bandage according to the invention, such a thread can be both dyed and sewn, since the inevitably occurring high temperatures can no longer dissolve the thread bandage both during dyeing and especially during sewing.

Für die Kombination eines solchen erfindungsgemäßen ganz oder weitgehend drehungslosen Fadens können alle an sich bekannten Faser- und Fadenmaterialien sowie deren Mischungen verwendet werden, wenn zur erfindungsgemäßen einmaligen Klebverbindung ein entsprechendes, nur einmal schmelzbares Fadenmaterial hinzugenommen ist. Die Faden- bzw. Faserverbindung im zusammengefaßten Fadenverband kann erfindungsgemäß auch durch die Zuführung eines solchen, nur einmal thermisch anteig- bzw. verflüssigbaren Stoffes, z.B. in Pulver oder flüssiger Form, erfolgen. Hierzu können alle an sich bekannten Techniken, z.B. Tauchen, Düsenbesprühung usw. angewandt werden.For the combination of such a completely or largely rotation-free thread according to the invention, all known fiber and thread materials and their mixtures can be used if a corresponding thread material which can only be melted once is added to the unique adhesive connection according to the invention. The thread or fiber connection in the combined thread structure can also be carried out according to the invention by supplying such a substance that can only be thermally pasted or liquefied once, for example in powder or liquid form. All techniques known per se, for example diving, nozzle spraying, etc. can be used for this.

Dieser erfindungsgemäß nur einmal thermisch-verflüssigbare, den Fadenverband zusammenverbindende Faden oder Stoff bzw. Material kann den übrigen Fadenanteilen zugeordnet verschieden gewählt werden. Es können z.B. Epoxy-oder Polyester-Harze sein, also sog. Zweikomponentenharze, die nach einer einmal stattgehabten thermischen Behandlung aushärten. Solche Harze sind z.B. mit der Artikelbezeichnung DD-Harze bekannt geworden. Erfindungsgemäß können es auch Desmofen- oder Desmodur-Harze sein. Je nach Wahl der übrigen Fadenanteile und der letztlichen Fadenverwendung können es z.B. auch Polypropylen oder Polyamid oder Polyäthylen-Fäden oder Pulver solchen Materials sein, das zur einmaligen thermischen Verbindung verwendet wird.This thread or fabric or material, which is thermally liquefiable only once and connects the thread assembly according to the invention, can be selected to be different depending on the other thread components. For example Epoxy or polyester resins, so-called two-component resins, which cure after a thermal treatment that has taken place once. Such resins are e.g. became known with the article name DD resins. According to the invention, it can also be Desmofen or Desmodur resins. Depending on the choice of the remaining thread components and the final thread usage, e.g. also be polypropylene or polyamide or polyethylene threads or powder of such material that is used for the one-time thermal connection.

Die Erfindung ist nicht an die Verwendung der vorstehend beispielsweise aufgeführten Stoffe bzw. chemischen Materialien gebunden; die Erfindung umfaßt vielmehr ein Verfahren das geeignet ist, mehrere gleiche oder verschiedene Einzelfäden oder eine entsprechende Anzahl Fasern durch thermische und ggf. gleichzeitige mechanische Behandlung so zusammen zu verbinden, daß eine nachfolgende Auflösung durch erneute Temperatureinwirkung ausgeschlossen bleibt, gründend auf den Umstand, daß die thermisch verklebfähigen Fäden oder Materialkomponenten nur eine einmalige thermische Veränderung zulassen.The invention is not tied to the use of the substances or chemical materials listed above, for example; Rather, the invention comprises a method which is suitable for combining several identical or different individual threads or a corresponding number of fibers by means of thermal and possibly simultaneous mechanical treatment in such a way that subsequent dissolution due to renewed exposure to temperature is excluded, based on the fact that the threads or material components that can be thermally bonded only allow a single thermal change.
