Description

Die Erfindung betrifft einen textilen Haftverschluß, der aus einem Schlaufenteil und einem Hakenteil besteht, wobei die Haken des Hakenteils aus Draht gebildet sind.The invention relates to a textile fastener, which consists of a loop part and a hook part, the hooks of the hook part being formed from wire.

Durch die DE-AS 16 10 459 ist ein textiler Haftverschluß dieser Art bekannt. Dieser bekannte Haftverschluß besteht aus Metallitzen, um Temperaturen, die höher als 150 °C sind, standzuhalten. Damit jedoch diese bekannten Haftverschlüsse eine ausreichende Biegsamkeit haben, müssen sehr dünne Metalldrähte verwendet werden. Die hierfür notwendigen dünnen Metalldrähte sind jedoch wesentlich teurer als Kunststoffäden oder -garne. Auch liegt der Fertigungsaufwand dieser metallischen Haftverschlüsse erheblich über demjenigen der Haftverschlüsse aus Kunststoffäden oder -garnen.A textile fastener of this type is known from DE-AS 16 10 459. This known fastener consists of metal strands to withstand temperatures that are higher than 150 ° C. However, for these known fasteners to have sufficient flexibility, very thin metal wires must be used. However, the thin metal wires required for this are much more expensive than plastic threads or yarns. The manufacturing outlay of these metallic adhesive fasteners is considerably higher than that of the adhesive fasteners made of plastic threads or yarns.

Der Erfindung liegt daher die Aufgabe zu Grunde, einen textilen Haftverschluß zu schaffen, der nicht nur eine hohe, weit über 150 °C liegende Flammfestigkeit hat, sondern hinsichtlich des Herstellungsaufwandes und der Kosten den Haftverschlüssen aus Kunststoffäden oder-garnen im wesentlichen entspricht.The invention is therefore based on the object to provide a textile fastener which not only has a high flame resistance, which is well above 150 ° C., but essentially corresponds to the fasteners made of plastic threads or yarns in terms of production costs and costs.

Diese Aufgabe löst ein Haftverschluß mit den Merkmalen des Anspruchs 1.This object is achieved by a fastener with the features of claim 1.

Dank der Carbonfasern liegt die Flammfestigkeit des erfindungsgemäßen Haftverschlusses über 1000 °C. Dennoch ist der textile Charakter in vollem Umfang gewährleistet, da die Carbonfasern in Form von Fäden oder Garnen zur Verfügung stehen, deren textiler Charakter mit demjenigen von textilen Fäden und Garnen weitgehend übereinstimmt, weshalb auch die gleichen Fertigungsverfahren angewendet werden können, nach denen textile Haftverschlüsse aus Kunststoffäden und -garnen hergestellt werden. Der Fertigungsaufwand der erfindungsgemäßen Haftverschlüsse entspricht daher im wesentlichen dem Fertigungsaufwand textiler Haftverschlüsse aus Kunststoffäden und -garnen. Dies ist auch für eine hochautomatisierte Nähtechnik von Bedeutung. Ein weiterer, wesentlicher Vorteil des erfindungsgemäßen Haftverschlusses besteht darin, daß er chemisch gereinigt werden kann. Im Vergleich zu einem Haftverschluß, der vollständig aus Metallitzen besteht, sind ferner die wesentlich geringeren Kosten der Carbonfäden gegenüber den dünnen Metalldrähten ein wichtiger Vorteil.Thanks to the carbon fibers, the flame resistance of the adhesive closure according to the invention is above 1000 ° C. Nevertheless, the textile character is fully guaranteed, since the carbon fibers are available in the form of threads or yarns, the textile character of which largely corresponds to that of textile threads and yarns, which is why the same manufacturing processes can be used according to which textile fasteners are made Plastic threads and yarns are made. The manufacturing cost of the fasteners according to the invention therefore corresponds essentially to the manufacturing cost of textile fasteners made of plastic threads and yarns. This is also important for highly automated sewing technology. Another essential advantage of the adhesive fastener according to the invention is that it can be cleaned chemically. Compared to an adhesive fastener made entirely of metal strands, the significantly lower cost of the carbon threads compared to the thin metal wires is also an important advantage.

Da die Haken des Hakenteils aus Draht, vorzugsweise einem nicht rostenden Federstahlmaterial bestehen, wäre es möglich, auch das Grundmaterial des Hakenteils aus Metalldrähten herzustellen, also den vollständig aus Carbonfasern bestehenden Schlaufenteil zusammen mit einem Hakenteil zu verwenden, dessen Grundmaterial aus Drähten besteht oder Drähte enthält. Im Hinblick auf die vorstehend erwähnten Vorteile, weiche sich mit den Carbonfasern erreichen lassen, ist es jedoch in der Regel vorteilhafter, auch das Grundmaterial des Hakenteils ausschließlich aus Carbonfasern herzustellen.Since the hooks of the hook part consist of wire, preferably a non-rusting spring steel material, it would be possible to also produce the base material of the hook part from metal wires, i.e. to use the loop part made entirely of carbon fibers together with a hook part whose base material consists of wires or contains wires . In view of the advantages mentioned above, which can be achieved with the carbon fibers, however, it is generally more advantageous to also produce the base material of the hook part exclusively from carbon fibers.

Sowohl aus Fertigungsgründen als auch im Hinblick auf den textilen Charakter des flächenhaften Hakenverschlußes werden die Carbonfasern vorzugsweise in Form von Garnen verarbeitet. Sowohl der Schlaufenteil als auch der Hakenteil lassen sich dann beispielsweise nach der üblichen Webetechnik herstellen, bei welcher die Schlaufen und Haken mit Hilfe von Polfäden gebildet werden, deren Schlingen beim Hakenteil zur Bildung der Haken seitlich aufgeschnitten werden.The carbon fibers are preferably processed in the form of yarns, both for manufacturing reasons and with regard to the textile character of the flat hook fastener. Both the loop part and the hook part can then be produced, for example, by the customary weaving technique, in which the loops and hooks are formed with the help of pile threads, the loops of which are cut open laterally in the hook part to form the hooks.

Im folgenden ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im einzelnen erläutert. Es zeigen

  • Fig. 1 eine schematisch dargestellte Draufsicht auf einen Abschnitt eines bandförmigen Schlaufenteils,
  • Fig. 2 eine schematisch dargestellte Draufsicht auf einen Abschnitt des zugehörigen, bandförmigen Hakenteils,
  • Fig. 3 einen vergrößert sowie perspektivisch und schematisch dargestellten Ausschnitt aus Fig. 1,
  • Fig. 4 einen vergrößert sowie perspektivisch und schematisch dargestellten Ausschnitt aus Fig. 2.
The invention is explained in detail below using an exemplary embodiment shown in the drawing. Show it
  • 1 is a schematic plan view of a section of a band-shaped loop part,
  • 2 shows a schematically illustrated plan view of a section of the associated band-shaped hook part,
  • 3 shows an enlarged and perspective and schematic section of FIG. 1,
  • FIG. 4 shows an enlarged and perspective and schematically illustrated section from FIG. 2.

Der als Ganzes mit 1 bezeichnete Schlaufenteil eines bandförmigen Haftverschlußes besteht aus einem Grundgewebe 2 sowie über die eine Seite dieses Grundgewebes überstehenden Schlaufen 3. Das Grundgewebe 2 ist in einer bei Haftverschlüßen üblichen Webetechnik unter Bildung je eines Nährandes 4 hergestellt. In Fig. 3 sind die Kettfäden mit 5, die Schußfäden mit 6 bezeichnet. Zwischen den beiden Nährändern 4 in Richtung der Kettfäden 5 verlaufende Polkettfäden bilden die Schlaufen 3, welche, wie Fig. 1 zeigt, im Ausführungsbeispiel in Doppelreihen angeordnet sind, welche sich vom einen zum anderen Nährand 4 in Schußrichtung erstrecken. Der in Kettrichtung gemessene Abstand zweier benachbarter Doppelreihen ist größer als der Abstand zwischen den beiden eine Doppelreihe bildenden Schlaufenreihen.The loop part of a band-shaped adhesive fastener, designated as a whole by 1, consists of a base fabric 2 and loops 3 protruding from one side of this base fabric. In Fig. 3, the warp threads 5, the weft threads 6. Between the two sewing edges 4 in the direction of the warp threads 5, pile warp threads form the loops 3, which, as shown in FIG. 1, are arranged in double rows in the exemplary embodiment, which extend from one sewing edge 4 to the other in the weft direction. The distance between two adjacent double rows measured in the warp direction is greater than the distance between the two rows of loops forming a double row.

Sowohl die Kettfäden 5 als auch die Schußfäden 6 und die die Schlaufen 3 bildenden Polkettfäden bestehen aus einem Carbonfasergarn, beispielsweise einem unter dem Warenzeichen « SIGRAFILSPO » auf dem Markt erhältlichen gezwirnten Garn.Both the warp threads 5 and the weft threads 6 and the pile warp threads forming the loops 3 consist of a carbon fiber yarn, for example a twisted yarn available on the market under the trademark “SIGRAFILSPO”.

Der zugehörige Hakenteil 7 hat ein Grundgewebe 8, das wie das Grundgewebe 2 des Schlaufenteils 1 unter Bildung je eines Nährandes 9 nach einer bekannten Webtechnik hergestellt ist, wobei ebenso wie bei dem Schlaufenteil sowohl die - Kettfiäden 10 als auch die Schußfäden 11 aus einem Carbonfasergarn bestehen. Im Ausführungsbeispiel handelt es sich um das gleiche Garn, aus dem der Schlaufenteil 1 gewebt ist.The associated hook part 7 has a base fabric 8, which, like the base fabric 2 of the loop part 1, is produced with the formation of a sewing edge 9 according to a known weaving technique, whereby, like the loop part, both the warp threads 10 and the weft threads 11 consist of a carbon fiber yarn . In the exemplary embodiment, it is the same yarn from which the loop part 1 is woven.

Zwischen den beiden Nährändern 9 verlaufen in Kettrichtung Polkettfäden, die aus einem nicht rostenden Federstahl bestehen und zunächst Schlaufen bilden, die anschließend zur Bildung von Haken 12 im Bereich des einen Schlaufenschenkels aufgeschnitten werden. Die Haken 12 sind wie die Schlaufen 3 jeweils in Doppelreihen angeordnet, die sich in Schußrichtung vom einen zum anderen Nährand 9 erstrecken, und auch hier ist der Abstand zwischen benachbarten Doppelreihen größer als zwischen den beiden Hakenreihen, welche jeweils eine Doppelreihe bilden.Between the two sewing edges 9 run in the warp direction pile warp threads, which consist of a stainless spring steel and initially Form loops, which are then cut open to form hooks 12 in the area of one loop leg. The hooks 12, like the loops 3, are each arranged in double rows which extend from one to the other sewing edge 9 in the weft direction, and here too the distance between adjacent double rows is greater than between the two rows of hooks, which each form a double row.

Sowohl der Schlaufenteil 1 als auch der Hakenteil 7 haben einen textilen Charakter, so daß sie wie textile Haftverschlüsse verarbeitet, insbesondere angenäht werden können. Ihre Flammfestigkeit liegt jedoch weit über derjenigen von textilen Haftverschlüssen, nämlich über 1000 °C.Both the loop part 1 and the hook part 7 have a textile character, so that they can be processed like textile adhesive fasteners, in particular sewn on. However, their flame resistance is far higher than that of textile fasteners, namely above 1000 ° C.

Alle in der vorstehenden Beschreibung erwähnten sowie auch die nur allein aus der Zeichnung entnehmbaren Merkmale sind als weitere Ausgestaltungen Bestandteile der Erfindung, auch wenn sie nicht besonderes hervorgehoben und insbesondere nicht in den Ansprüchen erwähnt sind.All of the features mentioned in the above description and also the features that can only be inferred from the drawing are further refinements of the invention, even if they are not particularly emphasized and in particular are not mentioned in the claims.
