Description

Die Erfindung betrifft ein gewebtes Textilgebilde, bestehend aus einer oberen Weblage und einer unteren Weblage, die an ihren Rändern zumindest teilweise miteinander verbunden sind, wobei Kettfäden und Schußfäden miteinander verwebt sind, und die Schußfäden eine größere Elastizität als die Kettfäden aufweisen.The invention relates to a woven textile structure consisting of an upper weave and a lower weave, which are at least partially connected to one another at their edges, wherein Warp threads and weft threads are woven together, and the weft threads have greater elasticity than the warp threads have.

Solche Textilgebilde, die zur Herstellung von Bezügen, wie Sitzmöbelbezügen, Kissenbezügen oder dergleichen, oder von Taschen, etc. verwendet werden können, werden herkömmlicherweise dadurch hergestellt, daß entweder zwei gleichbemessene, z. B. rechteckige, Textilstücke zuerst gewebt, später aufeinandergelegt und dann an drei Seiten aneinandergenäht werden, oder daß ein längeres, gewebtes, z. B. rechteckiges, Textilstück um eine Umlegelinie umgeklappt und dann entlang seiner beiden Seitenkanten vernäht wird, um ein sackartiges Textilgebilde zu erhalten, dessen weitere Verarbeitung vom Endprodukt abhängt. Such textile structures that are used to manufacture covers, such as seat covers, cushion covers or the like, or bags, etc. can be used conventionally manufactured in that either two equal, z. B. rectangular, textile pieces first woven, later placed on top of one another and then sewn together on three sides, or that one longer, woven, e.g. B. rectangular, piece of textile folded over a folding line and then is sewn along its two side edges to obtain a sack-like textile structure, the further processing depends on the end product.

Die herkömmlichen Herstellungsverfahren weisen jedoch eine Reihe von Nachteilen auf:

  • So ist es zu einer exakten mustermäßigen Aufeinanderlegung zweier Textilstücke oder Umlegung eines Textilstückes notwendig, sehr genau zu arbeiten, was zeit- sowie arbeitsaufwendig und somit kostenintensiv ist und somit zu einem teuren Endprodukt führt.
  • Zudem ist eine genähte Verbindung zwischen einer oberen und einer unteren Weblage, insbesondere bei hohen Beanspruchungen der Textilgebilde, sei es einmalig, beispielsweise beim Ausschäumen zum Herstellen eines Kissens oder beim Streifen eines Bezugs über einen Sitzmöbelrahmen, oder durch häufiges Benutzen, nicht ausreichend fest, sondern führt oft zu einem mangelhaften Endprodukt.
  • Auch gibt es empfindliche Därme und empfindlich Strukturen, wie beispielsweise Netzstrukturen, die durch Nähen nicht zuverlässig miteinander verbunden werden können, so daß das Textilgebilde dann von verminderter Qualität ist.
    • However, the conventional manufacturing processes have a number of disadvantages:
  • For example, it is necessary for an exact pattern-based stacking of two pieces of textile or folding of a piece of textile to work very precisely, which is time-consuming and labor-intensive and therefore cost-intensive and thus leads to an expensive end product.
  • In addition, a stitched connection between an upper and a lower weave layer, especially when the textile structures are subjected to high loads, be it unique, for example when foaming to make a cushion or when a cover is slipped over a seating frame, or through frequent use, but not sufficiently strong, but often leads to a defective end product.
  • There are also sensitive intestines and sensitive structures, such as, for example, mesh structures, which cannot be reliably connected to one another by sewing, so that the textile structure is then of reduced quality.

    • Aus der US-PS 3,286,739 ist ein Verfahren zur Herstellung von nahtlosen Taschen für Kleidungsstücke bekannt. Dabei wird ein Stoff hergestellt mit einem Muster aus ersten Gewebebereichen, die aus zwei übereinander liegenden Hohlgeweblagen bestehen und durch zweite, einlagige Gewebebereiche verbunden sind, so daß die Taschen durch Schneiden des Stoffes in den einlagigen Bereichen gewonnen werden. Zur Verstärkung der einlagigen Bereiche werden vorzugsweise thermoplastische Garne verwendet, welche nach dem Schneiden thermoplastisch miteinander verbunden werden.US Pat. No. 3,286,739 describes a method for producing seamless bags for clothing known. A fabric is made with a pattern from the first fabric areas, which consist of two superimposed hollow fabric layers and second, single-layer fabric areas are connected so that the pockets by cutting the fabric in the single-layer areas be won. Thermoplastic materials are preferably used to reinforce the single-layer areas Yarns used, which are thermoplastic bonded together after cutting become.

    Die EP 0 408 467 A1 offenbart ein Verfahren zur Herstellung von Beuteln durch Weben auf einer konventionellen Webmaschine mit vier Webschäfte. Bei diesem Verfahren entsteht ebenfalls ein gewebter Stoff, der aus sich abwechselnden ein- und zweilagigen Bereichen besteht. EP 0 408 467 A1 discloses a method for producing bags by weaving on a conventional weaving machine with four heald frames. This procedure also creates a woven fabric consisting of alternating one and two-layer areas.

    Aus der EP 0 363 490 A1 sind nahtlos gewebte Airbags, jeweils ausgeschnitten aus einem ersten rohrformigen Bereich mit quer zur Längsrichtung desselben verlaufenden zweiten Bereichen, bekannt.EP 0 363 490 A1 describes seamlessly woven airbags, each cut out of a first tubular region with transverse to the longitudinal direction of the same extending second regions known.

    In der US-PS 4,205,709 ist ein gattungsgemäßes Textilgebilde zur Aufnahme von Akkumulatorelementen offenbart. Dabei dienen erste, zweilagige Bereiche zur Aufnahme der aktiven Masse der Akkumulatoren und sind durch zweite, einlagige Bereiche voneinander getrennt. Der Kettund/oder Schußfäden sind aus Metalldrähten ausgebildet, oder eine der Weblagen der zweilagigen Bereiche besteht aus Metalldrähten, während die andere Weblage der zweilagigen Bereiche aus einem anderen Material besteht. Um eine konvexe Form einer der beiden Weblagen in einem zweilagigen Bereich zu erreichen, wird die Verwendung von Materialien verschiedener Elastizität vorgeschlagen.US Pat. No. 4,205,709 describes a generic textile structure for holding accumulator elements disclosed. The first two-layer areas serve to absorb the active mass of the accumulators and are separated from one another by second, single-layer areas. The warp and / or Weft threads are made of metal wires, or one of the woven layers of the two-layer Areas consist of metal wires, while the other weave of the two-layer areas another material. To a convex shape of one of the two layers of weave in one To achieve double-layer area, the use of materials of different elasticity proposed.

    Aufgabe der Erfindung ist es, das gattungsgemäße Textilgebilde dahingehend weiterzuentwickeln, daß die Nachteile des Stands der Technik überwunden werden, insbesondere das Textilgebilde automatisch, kostengünstig und qualitativ hochwertig herstellbar wird.The object of the invention is to further develop the generic textile structure in such a way that that the disadvantages of the prior art are overcome, in particular the textile structure is automatically, inexpensively and of high quality.

    Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die unelastischen Kettfäden dünner als die elastischen Schußfäden sind.According to the invention, this object is achieved in that the inelastic warp threads are thinner than the elastic wefts are.

    Dabei ist erfindungsgemäß bevorzugt, daß die beiden Weblagen an den Rändern über eine Webverbindung verwebt oder mit einer Kantendrehverbindung verbunden sind.It is preferred according to the invention that the two weave layers on the edges over a Web connection are woven or connected with an edge twist connection.

    Bevorzugt ist vorgesehen, daß die Kettfäden ein Titer von 450 dtex aufweisen.It is preferably provided that the warp threads have a titer of 450 dtex.

    Ferner wird mit der Erfindung vorgeschlagen, daß die Schußfäden aus Därmen gebildet sind. It is also proposed with the invention that the weft threads are formed from intestines.

    Dabei kann vorgesehen sein, daß das Textilgebilde von einem durch eine sack- oder schlauchartige Ausbildung gekennzeichnet ist.It can be provided that the textile structure from one through a sack or hose Training is marked.

    Schließlich kann vorgesehen sein, daß das Textilgebilde von einem Möbelbezug, einem Kissenbezug oder einer Tasche umfaßt ist.Finally, it can be provided that the textile structure of a furniture cover, a pillow case or a bag is included.

    Der Erfindung liegt somit die überraschende Erkenntnis zugrunde, daß ein kostengünstiges und qualitativ hochwertiges Textilgebilde, wie ein Möbelbezug, ein Kissenbezug, eine Tasche oder dergleichen, herstellbar ist, indem bei dem Textilgebilde in exakter mustermäßiger Zuordnung der oberen Weblage zur unteren Weblage unelastische Kettfäden, welche dünner als die elastischen Schußfäden sind, mit diesen Schußfäden miteinander verwebt sind. Dies ist mit folgenden Vorteilen verbunden:

  • Bei, insbesondere komplizierten, Mustern ist eine exakte mustermäßige Orientierung der Weblagen zueinander automatisch gewährleistet, was preisgünstig zu einem optisch einwandfreien Textilgebilde führt.
  • Wenn das Zusammenfügen der Ränder nicht durch Nähen, sondern durch Weben erfolgt, wird Faden für Faden eine feste Verbindung zwischen der oberen Weblage und der unteren Weblage erreicht, so daß das Textilgebilde hohe Spannungen aufnehmen kann.
  • Empfindliche Därme, die durch Nähen nicht zuverlässig miteinander verbunden sind, beispielsweise in Netzstrukturen, sind bei dem erfindungsgemäßen Textilgebilde einfach miteinander verwebt.
    • The invention is therefore based on the surprising finding that an inexpensive and high-quality textile structure, such as a furniture cover, a pillow case, a bag or the like, can be produced by inelastic warp threads in the textile structure in exact pattern assignment of the upper weave to the lower weave are thinner than the elastic weft threads are interwoven with these weft threads. This has the following advantages:
  • In the case of, in particular complicated, patterns, an exact pattern-oriented orientation of the weaving layers with respect to one another is automatically guaranteed, which leads to an optically perfect textile structure at low cost.
  • If the edges are joined together not by sewing but by weaving, a firm connection between the upper weave layer and the lower weave layer is achieved thread by thread, so that the textile structure can absorb high tensions.
  • Sensitive intestines that are not reliably connected to one another by sewing, for example in mesh structures, are simply woven together in the textile structure according to the invention.

    • Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel der Erfindung anhand von schematischen Zeichnungen im einzelnen erläutert ist. Dabei zeigt:

    Figur 1
    eine Draufsicht auf einen Abschnitt eines erfindungsgemäß hergestellten sackartigen Textilgebildes; und
    Figur 2
    eine Schnittansicht des in Figur 1 gezeigten Textilgebildes entlang der Verbindungslinie B-II.
    Further features and advantages of the invention result from the following description, in which an embodiment of the invention is explained in detail with the aid of schematic drawings. It shows:
    Figure 1
    a plan view of a portion of a bag-like textile structure produced according to the invention; and
    Figure 2
    a sectional view of the textile structure shown in Figure 1 along the connecting line B-II.

    Das in den Figuren 1 und 2 gezeigte Textilgebilde 1 besteht aus einer oberen Weblage 2, einer unteren Weblage 3 und einer Webverbindung 4 längs dreier Kanten der beiden Weblagen 2, 3 und weist somit eine sackartige Gestalt aufThe textile structure 1 shown in FIGS. 1 and 2 consists of an upper weave layer 2, one lower weave layer 3 and a weave connection 4 along three edges of the two weave layers 2, 3 and thus has a sack-like shape

    Das Textilgebilde 1 läßt sich wie folgt herstellen:

  • In einer Webmaschine mit einer Schaftmaschine, die beispielsweise vierundzwanzig Webschäfte aufweist, werden in bekannter Weise übereinanderliegende Einzel-Gewebelagen zum Herstellen der oberen Weblage 2 und der unteren Weblage 3 gewebt und gleichzeitig in der Webmaschine, in exakter mustermäßiger Aufeinanderorientierung, an den in Kettrichtung verlaufenden beiden Kanten Faden für Faden miteinander verwebt. Dies kann durch den gezielten Einsatz von Webschäften erreicht werden.
  • Der Abschnitt der Webverbindung 4, der senkrecht zur Kettrichtung verläuft, kann dann durch entsprechendes Hoch- bzw. Herunterführen der für die obere Weblage 2 bzw. für die untere Weblage 3 verwendeten Kettfäden unter Einschießen einiger Schußfäden hergestellt werden.
  • Das Zuschneiden durch entsprechende Querschnitte kann entweder noch beim Textilhersteller oder aber später beim Hersteller des Endprodukts, beispielsweise beim Möbelhersteller oder Taschenhersteller, vorgenommen werden.
    • The textile structure 1 can be produced as follows:
  • In a weaving machine with a dobby, which has, for example, twenty-four heald frames, individual fabric layers lying one above the other are woven in a known manner to produce the upper weave layer 2 and the lower weave layer 3 and at the same time in the weaving machine, in an exact pattern-oriented orientation, on the two running in the warp direction Edges thread by thread woven together. This can be achieved through the targeted use of heald frames.
  • The section of the weave connection 4 that runs perpendicular to the warp direction can then be produced by appropriately raising or lowering the warp threads used for the upper weave layer 2 or for the lower weave layer 3 while shooting in some weft threads.
  • The cutting through appropriate cross-sections can be carried out either at the textile manufacturer or later at the manufacturer of the end product, for example at the furniture manufacturer or bag manufacturer.

    • Die in der vorstehenden Beschreibung, in den Zeichnungen sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in jeder beliebigen Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein. Those disclosed in the foregoing description, in the drawings, and in the claims Features of the invention can be used individually or in any combination for the Realization of the invention in its various embodiments may be essential.
