Abstract

A textile material comprises at least two different needled base non-wovens which show a structure on at least one side produced by needle punching. The needles used are forked or crowned to a depth that ensures that they are completely filled with fibres from the entry side. Only unmixed fibres appear in the pattern, in the background and on the back. Also claimed are: (i) the initial laminating of the two layers without activating melt fibres contained in them, needling to form the structure, and then activating the melt fibres; and (ii) the initial laminating of the two layers by an adhesive layer.

Description

Technisches GebietTechnical field

Ein strukturiertes Textilmaterial aus mindestens zwei verschiedenen Basisvliesen findet insbesondere als Reinigungstextilie Verwendung.A structured textile material made up of at least two various basic nonwovens are found in particular as Cleaning textile use.

Stand der TechnikState of the art

Eine Reinigungstextilie aus einem strukturierten Textilmaterial aus mindestens zwei Basisvliesen ist aus der WO 94 23 634 bekannt. Weiterhin ist aus der WO 90 14 039 ein strukturiertes textiles Flächenmaterial bekannt, welches aus einem Vlies besteht, aus welchem eine Vielzahl von Fadenschlaufen beziehungsweise Faserenden durch Nadelung hervorgehoben sind.A cleaning textile made from a structured Textile material made from at least two base nonwovens is made from WO 94 23 634 known. Furthermore, from WO 90 14 039 structured textile surface material known, which from a fleece, from which a variety of Thread loops or fiber ends by needling are highlighted.

Ein Verfahren zur seiner Herstellung ist in der GB 2 162 213 offenbart. Dort werden die Strukturen durch Nadeln eines Vlieses hergestellt, wobei Fasern oder Filamente aus der Gegenfläche mittels Widerhaken herausgezogen werden, wodurch die Strukturen aus hauptsächlich Material der jeweils gegenüberliegenden Fläche bestehen.A process for its production is in GB 2 162 213 disclosed. There the structures are made by needling one Nonwoven manufactured, with fibers or filaments from the The counter surface can be pulled out using barbs, whereby the structures mainly made of material of each opposite surface exist.

Der Nachteil von bislang bekannten strukturierten Textilmaterialen aus mindestens zwei verschiedenen unverfestigten Basisvliesen besteht darin, daß bereits durch die Vernadelung der beiden unverfestigten Basisvliese auf der Ausstichseite ein Basisvlies in einer Mischfarbe entsteht. Auch bei der Herstellung der Strukturierungen mittels Durchnadeln der Fasern eines Basisvlieses durch das andere Basisvlies entstehen weitere Mischeffekte, die das fertige Textilmaterial unschön aussehen lassen und die spezifischen Gebrauchseigenschaften des Fasermaterials eines Basisvlieses abschwächen.The disadvantage of previously known structured Textile materials from at least two different unconsolidated base fleece consists in that already through the needling of the two unconsolidated base nonwovens a base fleece in a mixed color on the cut-out side arises. Also in the production of the structuring by needling the fibers of a base fleece through the other basic fleece, further mixing effects arise that the finished textile material look ugly and the specific usage properties of the fiber material Weaken the base fleece.

Die Aufgabe besteht darin, ein strukturiertes Textilmaterial aus mindestens zwei verschiedenen Basisvliesen zu schaffen, bei dem eine Vermischung der Fasern vermieden wird.The task is to create a structured textile material to create from at least two different basic fleeces, in which mixing of the fibers is avoided.

Darstellung der ErfindungPresentation of the invention

Erfindungsgemäß weisen die Basisvliese eine durch Nadelung von mindestens einer Seite erhaltene Struktur auf, wobei die zur Strukturnadelung verwendeten Nadeln Gabel- oder Kronennadeln sind und die Tiefe der Gabein beziehungsweise der Bärte so gewählt ist, daß sich diese beim Durchstich vollständig mit Fasern des den Nadeln zugewandten Basisvlieses füllen und wobei das Textilmaterial im Muster, im Fond und auf der Rückseite unvermischte, reine Fasern aufweist.According to the invention, the base nonwovens have a needling structure obtained from at least one side, the needles used for structural needles fork or Crown needles are and the depth of the Gabein respectively the beards are chosen so that they are at the puncture completely with fibers of the needles Fill the base fleece and the textile material in the pattern, unmixed, pure fibers in the back and on the back having.

Ein Textilmaterial mit diesen Merkmalen hat den Vorteil, daß die spezifischen Gebrauchseigenschaften des Fasermaterials eines Basisvlieses bei der Strukturierung erhalten bleiben. Im Falle verschiedener Farben der Basisvliese werden reine Farben im Muster, im Fond und auf der Rückseite erhalten. Hierdurch lassen sich auch optische Effekte erzielen.A textile material with these features has the advantage that the specific usage properties of the fiber material of a base fleece are retained during the structuring. In the case of different colors of the base fleeces, they become pure Preserved colors in the pattern, in the back and on the back. This also allows optical effects to be achieved.

Zur Erhöhung der Spaltfestigkeit können die Schmelzfasern aufweisenden Basisvliese miteinander kaschiert sein und wird die Verbindung der beiden Basisvliese durch Aktivierung der vertikal getstellten Schmelzfasern noch verstärkt. Für das Kaschieren sind im Prinzip alle bekannten Verfahren und alle bekannten Bindemittel einsetzbar, wobei jedoch diejenigen vorzuziehen sind, die eine gute Verklebung und eine geringe Versteifung des Textilmaterials geben und eine Waschbeständigkeit von mindestens 60°C, besser noch 95°C erbringen.The melt fibers can be used to increase the splitting strength having base nonwovens and will be laminated together the connection of the two base fleeces by activating the vertically placed enamel fibers are reinforced. For the In principle, lamination is all known processes and all known binders can be used, but those are preferred, which is good bonding and low Stiffen the textile material and give one Wash resistance of at least 60 ° C, better still 95 ° C provide.

Vorteilhafterweise weist mindestens ein Basisvlies Schmelzfasern auf, die in ihren Eigenschaften so ausgewählt sind, daß sie während des Kaschierens nicht aktiviert werden. Hierdurch wird es möglich, die nicht gebundenen Basisvliese durch Nadelung mit den gewünschten Strukturen zu versehen.At least one base fleece advantageously has Melting fibers based on their properties selected are that they are not activated during lamination become. This makes it possible for the unbound Basic fleeces by needling with the desired structures Mistake.

Für die Kaschierung der beiden Basisvliese kann ebenso zwischen die beiden Schmelzfasern aufweisenden Basisvliese eine Zwischenlage aus einem eine Klebung der beiden Basisvliese vermögenden Werkstoff, insbesondere ein Klebevlies, eingebracht sein und kann die Verbindung der beiden Basisvliese und der Zwischenlage durch Aktivierung der Schmelzfasern und der Zwischenlage hergestellt sein. Zwar besteht die Gefahr, daß Anteile der Zwischenlage in die Struktur mit eingenadelt werden, dies kann aber unter Umständen sogar erwünscht sein und erhöht die Spaltfestigkeit.The same applies to the lamination of the two base nonwovens between the two non-woven base fibers an intermediate layer made of a glue of the two Base nonwovens wealthy material, especially a Adhesive fleece, can be introduced and the connection of the both base fleece and the liner by activation the melt fibers and the intermediate layer. Although there is a risk that portions of the intermediate layer in the Structure with needles, but this can be done under Circumstances may even be desired and increases the Gap resistance.

Obwohl die Wahl der Seiten der zu verbindenden Basisvliese grundsätzlich für die vorliegende Erfindung egal ist, ist es vorteilhaft, wenn die Durchstichseiten der durch Nadelung von einer Seite verfestigten Basisvliese einander zugewandt sind.Although the choice of the sides of the base fleece to be connected basically does not matter for the present invention, it is advantageous if the puncture sides of the needling Base fleeces solidified on one side facing each other are.

Um die Wirkung der Strukturierungen zu verstärken, können die Basisvliese unterschiedliche Materialeigenschaften, insbesondere der Reinigungsfähigkeit aufweisen.To reinforce the effect of the structuring, you can the basic fleeces have different material properties, in particular the cleanability.

Ein erfindungsgemäßes Verfahren zur Herstellung eines aus mindestens zwei verschiedenen Basisvliesen bestehenden strukturierten Textilmaterials mit durch Nadelung entstandenen ein- oder zweiseitigen Strukturen, wobei das Textilmaterial im Muster, im Fond und auf der Rückseite unvermischte, reine Fasern aufweist, besteht darin, daß eine Kaschierung der beiden Schmelzfasern aufweisenden vernadelten Basisvliese ohne Aktivierung der Schmelzfasern erfolgt, daß anschließend eine ein- oder zweiseitige Strukturnadelung erfolgt und daß die Schmelzfasern der Basisvliese nach der Strukturnadelung aktiviert werden.An inventive method for producing a existing at least two different base fleeces structured textile material with needling created one- or two-sided structures, whereby the Textile material in the pattern, in the back and on the back has unmixed, pure fibers is that a Lamination of the two enamel fibers needled base nonwovens without activation of the melt fibers takes place that then a one or two-sided Structural needling takes place and that the melting fibers of the Base fleeces are activated after the needling of the structure.

Gegenüber einem aus zwei unterschiedlichen miteinander vernadelten Vliesen bestehenden Textilmaterial hat man den Vorteil, daß die Basisvliese bis zur Strukturierung unvermischt bleiben. Die benötigte Festigkeit der Basisvliese erhält man durch getrenntes Nadeln der beiden Basisvliese vor der Kaschierung.Opposite one of two different ones Needled nonwovens existing textile material has the Advantage that the base fleece up to the structuring stay unmixed. The required strength of the Basic fleeces are obtained by needling the two separately Basic fleeces before lamination.

Ein weiteres Verfahren zur Herstellung eines aus mindestens zwei verschiedenfarbigen Basisvliesen bestehenden strukturierten Textilmaterials mit durch Nadelung entstandenen ein- oder zweiseitigen Strukturen, wobei das Textilmaterial im Muster, im Fond und auf der Rückseite unvermischte, reine Fasern aufweist, besteht darin, daß vor dem Einlauf in eine Strukturnadelmaschine zwischen die beiden Schmelzfasern aufweisenden vernadelten Basisvliese eine Zwischenlage aus einem eine Klebung der beiden Basisvliese vermögenden Werkstoff, insbesondere ein Klebevlies, eingebracht wird, daß die beiden Basisvliese und die Zwischenlage miteinander einer ein- oder zweiseitigen Strukturnadelung unterworfen werden und daß anschließend die Verbindung der beiden Basisvliese und der Zwischenlage durch Aktivierung der Schmelzfasern und der Zwischenlage hergestellt wird.Another method of making one from at least two different colored base fleeces structured textile material with needling created one- or two-sided structures, whereby the Textile material in the pattern, in the back and on the back has unmixed, pure fibers is that before the entry into a structural needle machine between the two needled base nonwovens with melt fibers an intermediate layer made of a glue of the two Base nonwovens wealthy material, especially a Adhesive fleece is introduced that the two base fleeces and the liner with one another on one or two sides Structural needling and then the Connection of the two base fleeces and the intermediate layer by Activation of the melt fibers and the liner will be produced.

Deses Verfahren eignet sich besonders für die einseitige Strukturierung. Es ist aber auch für die beidseitige Strukturierung einsetzbar, wenn durch das erste, einseitig aufgebrachte Muster soviel Stabilität erzeugt wird, daß ein zweiter Durchgang ohne Verschiebung der Lagen zueinander möglich ist.This method is particularly suitable for one-sided Structuring. But it is also for the bilateral Structuring can be used if through the first, one-sided applied pattern is so much stability that a second run without shifting the layers to each other is possible.

Zur Erlangung einer bestmöglichen Reinheit der Fasern ist das Verfahren vorteilhafterweise so zu führen, daß die zur Strukturnadelung verwendeten Gabel- oder Kronennadeln sich beim Durchstich vollständig mit Fasern des den Nadeln zugewandten Basisvlieses füllen.To achieve the best possible purity of the fibers to carry out the method advantageously so that the for Structural needles used fork or crown needles when piercing completely with fibers of the needles fill the facing base fleece.

Ausführung der ErfindungImplementation of the invention

Ausgehend von zwei in Fig. 1 dargestellten unterschiedlichen vernadelten Basisvliesen 1, 2 mit dem gewünschten Gewicht und den gewünschten Materialeigenschaften stellt man zunächst ein Laminat aus beiden Vliesen 1,2 her. Dieses Laminat besteht somit aus zwei Lagen reinen Materials.Starting from two different ones shown in FIG. 1 needled base fleece 1, 2 with the desired weight and the desired material properties first a laminate from both nonwovens 1, 2. This Laminate therefore consists of two layers of pure material.

Die beiden Basisvliese 1,2 sind miteinander kaschiert, wobei eine Klebezone 3 vorhanden ist. Die Klebezone 3 kann auch ein Klebevlies sein.The two base nonwovens 1, 2 are laminated together, whereby there is an adhesive zone 3. The adhesive zone 3 can also be an adhesive fleece.

Beim Kaschierprozeß wird eine Aktivierung der in den Basisvliesen 1,2 enthaltenen Schmelzfasern vermieden, sodaß anschließend die Herstellung der Strukturen 4 durch Nadelung erfolgen kann.In the lamination process, an activation of the in the Basis fleece 1,2 contained melt fibers avoided, so then the manufacture of the structures 4 by needling can be done.

Die Srukturen werden auf einer Strukturierungsnadelmaschine, z.B. Dilo, Di-Loop oder andere, mittels Gabel- oder Kronennadeln erezugt. Dabei ist die Tiefe der Gabeln beziehungsweise der Bärte auf das Faserangebot des Vlieses auf der Einstichseite abzustimmen, damit diese sich ganz mit den Fasern dieses Vlieses füllen.The structures are made on a structuring needle machine, e.g. Dilo, Di-Loop or others, using fork or Crown needles raised. Here is the depth of the forks or the beards on the fiber range of the fleece vote on the puncture side, so that this completely with fill the fibers of this fleece.

Anschließend wird das strukturierte Laminat thermofixiert. Dabei werden die im Basisvlies enthaltenen Schmelzfasern aktiviert. Sie verbinden die übrigen Fasern miteinander und erhöhen die Festigkeit der Basisvliese.The structured laminate is then heat set. The melt fibers contained in the base fleece activated. They connect the other fibers together and increase the strength of the base fleece.

Da beim Vernadeln der einzelnen Basisvliese und beim Strukturnadeln des Laminats Schmelzfasern entsprechend ihres Anteils in der Fasermischung quer durch das Material genadelt werden erhöht sich nach deren Aktivierung die Querstabilität oder Spaltfestigkeit des Textilmaterials.Because when needling the individual base fleeces and when Structural needles of the laminate melt fibers according to their Proportion in the fiber mixture across the material to be needled increases after their activation Cross stability or splitting strength of the textile material.

Bei Verwendung eines zwischen den Basisvliesen 1,2 angeordneten Klebevlieses 3 ist es möglich, die beiden Basisvliese 1,2 mit dem Klebevlies 3 zusammen in die Strukturnadelmaschine einlaufen zu lassen und alle drei Lagen miteinander durch Nadelung zu strukturieren.When using a between the base fleece 1,2 arranged adhesive fleece 3, it is possible to use the two Basic fleece 1,2 together with the adhesive fleece 3 in the Let the structural needle machine break in and all three Structuring layers with each other by needling.

Bei ausreichender Festigkeit des Laminats gegen Verschiebung der einzelnen Lagen durch die eingenadelte Struktur 4 ist es möglich, das Laminat zu wenden und erneut der Maschine zuzuführen.If the laminate is sufficiently strong against displacement of the individual layers through the needled structure 4 possible to turn the laminate and machine again feed.

Anschließend werden in einem Arbeitsgang die Schmelzfasern in den beiden Basisvliesen aktiviert und ebenso das Klebevlies für die Laminierung der beiden Basisvliese 1,2. Dies ist dann ohne weiteres möglich, wenn man die Schmelzfasern und das Material des Klebevlieses entsprechend der benötigten Aktivierungsbedingungen aufeinander abstimmt.The melt fibers are then processed in one operation activated in the two basic fleeces and likewise that Adhesive fleece for the lamination of the two base fleeces 1,2. This is easily possible if you have the Melt fibers and the material of the adhesive fleece accordingly the required activation conditions are coordinated.

Beide Vorgehensweisen erlauben dann, mittels zwei Strukturierungsprozessen in beide Seiten des Textilnaterials Strukturierungen 5,6 einzubringen, Fig. 2. Diese Strukturierungen 5,6 können längs verlaufende unterbrochene Streifen sein, die zur Vermeidung einer Übernadelung einen seitlichen Sicherheitsabstand d von mindestens 5 mm aufweisen.Both approaches then allow two Structuring processes in both sides of the textile material Introduce structures 5,6, Fig. 2. This Structurings 5,6 can be interrupted in the longitudinal direction Stripes that are a to avoid needling lateral safety distance d of at least 5 mm exhibit.

Die Strukturierungen 5 sind von der dem Betrachter zugewandten Seite auf die dem Betrachter abgewandte Seite genadelt, sodaß nur Schlitze sichtbar sind.The structures 5 are different from that of the viewer facing side on the side facing away from the viewer needled so that only slits are visible.

Die Strukturierungen 6 sind von der dem Betrachter abgewandten Seite auf die dem Betrachter zugewandte Seite genadelt, sodaß hier die über das Basisvlies hervorstehenden Faserbüschel sichtbar sind.The structures 6 are different from those of the viewer opposite side to the side facing the viewer needled, so that the protruding from the base fleece here Tufts of fibers are visible.

Insbesondere bei der Herstellung von farbreinen Mustern aus zwei unterschiedlich gefärbten Basisvliesen hat sich die Erfindung bewährt. Wird in ein Laminat aus zwei thermofixierbaren farbigen Nadelvliesen mit einer Strukturnadelmaschine einseitig ein Muster eingenadelt, so entsteht abhängig von der gewählten Einstichseite der Strukturnadeln bei beispielsweise einem roten und einem blauen Nadelvlies folgendes Produkt: Einstichseite rot Einstichseite blau Musterung/Strukturierung rot blau Fond um die Musterung blau rot Rückseite rot blau The invention has proven itself in particular in the production of pure-color patterns from two differently colored base nonwovens. If a pattern is needled on one side in a laminate of two heat-fixable colored needle felt with a structure needle machine, the following product is produced depending on the selected stitching side of the structure needles, for example with a red and a blue needle felt: Stitch side red Puncture side blue Patterning / structuring red blue Fund around the pattern blue red back red blue

Alle Farben sind unvermischt.All colors are unmixed.

Wenn man beidseitig strukturiert, also über die Breite des Materials beide Seiten im Wechsel in Streifensektoren in zwei Arbeitsgängen strukturvernadelt, dann erhält man ein Produkt, das abwechselnd, entsprechend dieser Streifensektoren auf der Ober- und Unterseite strukturiert ist.If you structure on both sides, i.e. across the width of the Materials alternating in stripe sectors in both sides two steps needling, then you get one Product that alternates, according to this Strip sectors structured on the top and bottom is.

Dabei ist die Strukturierung auf der einen Seite rot, auf der anderen blau. Die Farbe des Fonds und der Rückseite ist dann jeweils so wie in der vorstehenden Tabelle aufgezeigt.The structure is red on one side the other blue. The color of the fund and the back is then as shown in the table above.

Die unstrukturierten Abstände 7 der Breite d zwischen den gegenseitigen Streifensektoren 5,6 entsprechen in der Farbe den Basisvliesen vor ihrer Zuführung in die Strukturnadelmaschine.The unstructured distances 7 of width d between the mutual stripe sectors 5,6 correspond in color the basic nonwovens before they are fed into the Structural needle machine.
