Abstract

The material with a looped surface structure, as a contact closure with a material with a hooked structure, has a fibre or filament layer as a bulked fibres/filaments or a web of kinked or crimped fibres or filaments. Their bulk character is formed wholly by the geometric structure of the layer without any additional working. Two groups of narrow and parallel linear bonding zones intersect to form lozenge-shaped cushions with a looped surface structure.

Description

Die Erfindung betrifft ein Schlaufenmaterial einer Haken-Schlaufen-Verbindung nach dem Oberbegriff des Anspruchs 1.The invention relates to a loop material of a hook-loop connection according to the preamble of claim 1.

Zum Verschließen von Babywindeln waren bisher Adhäsionsverschlüsse üblich. Diese lassen sich zwar mehrfach öffnen und schließen, sind aber sehr empfindlich gegen Verschmutzung. Inzwischen wurden auch Haken-Schlaufen-Verbindungen bei Babywindeln eingesetzt. Diese Verbindungen werden auch als Klettverschlüsse bezeichnet.Adhesive closures were previously used to close baby diapers common. These can be opened multiple times and close, but are very sensitive to pollution. In the meantime, hook and loop connections have also been made in baby diapers used. These connections are also called Velcro fasteners designated.

Derartige Verschlüsse bestehen aus einem Flächengebilde, das eine Vielzahl kleiner mit Widerhaken versehener Stachel trägt und einem weiteren Flächengebilde, das mit Schlaufen versehen ist. Bei Kontakt der beiden Flächengebilde haken sich die Stacheln mit Ihren Widerhaken an den Schlaufen fest, so daß die beiden Flächengebilde zusammenhaften. Da die Stachel mit den Widerhaken elastisch sind, lassen sich die beiden Flächengebilde auch wieder trennen. Die Aushebekräfte sind relativ gering, während die Scherkräfte sehr groß sind. Da die Befestigung rein mechanisch erfolgt, ist eine Verschmutzung durch Flüssigkeit, Fett oder Emulsionen unschädlich für die Wirkungsweise.Such closures consist of a flat structure, the carries a variety of small barbed spikes and another fabric that has loops is. When the two fabrics come into contact, they hook Spines with your barbs firmly on the loops so that the two fabrics stick together. Since the sting with the barbs are elastic, the two fabrics can be also separate again. The lifting forces are relative low, while the shear forces are very large. Since the Fastening is done purely mechanically, is contamination through liquid, fat or emulsions harmless to the Mode of action.

Die sichere Funktion einer Haken-Schlaufen-Verbindung erfordert es, daß die Haken und die Schlaufen aneinander angepaßt sind, daß auch die Schlaufen eine ausreichende Festigkeit besitzen, damit sie beim Lösen des Verschlusses nicht zerstört werden und daß eine hohe statistische Sicherheit dafür gegeben ist, daß Haken mit Schlaufen auf einer vorgegebenen Fläche eine Verbindung eingehen.The secure functioning of a hook-loop connection requires it that the hooks and the loops matched to each other are that the loops also have sufficient strength, so that it does not destroy when the lock is released be given and that a high statistical certainty for it is that hooks with loops on a given area to connect.

Aus der EP 0 341 993 A1 ist ein Schlaufenmaterial bekannt, bei dem auf einer Trägerschicht eine Faserschicht aus glatten Fasern befestigt ist. Die Befestigung erfolgt durch schmale linienartige, parallel verlaufende Bondingbereiche. Die Fasern sind dabei alle einheitlich ausgerichtet und die Bondingbereiche verlaufen quer zur Ausrichtung der Fasern. Bei einer alternativen Ausgestaltung sind die Bondingbereiche unterbrochen und jeweils um die Hälfte ihres gegenseitigen Abstandes versetzt.A loop material is known from EP 0 341 993 A1, in which a fiber layer made of smooth on a carrier layer Fibers is attached. The attachment is made by narrow line-like, parallel bonding areas. The fibers are all aligned uniformly and the bonding areas run perpendicular to the orientation of the fibers. At In an alternative embodiment, the bonding areas are interrupted and each by half their mutual distance transferred.

Wegen der exakt einheitlichen Ausrichtung der Fasern ist es erforderlich, daß auch die Haken der Haken-Schlaufen-Verbindung entsprechend ausgerichtet sind, damit eine Verbindung zustandekommen kann. Sonst könnte der Fall eintreten, daß nur ein kleiner Teil der Haken die Schlaufen hintergreifen kann.Because of the exact uniform alignment of the fibers it is required that the hook of the hook-loop connection are aligned accordingly so that a connection can come about. Otherwise the case could occur that only a small part of the hooks reach behind the loops can.

Ferner ist aus der EP 0 765 616 A1 ein Schlaufenmaterial für eine Haken-Schlaufen-Verbindung bekannt, bei der ein Gewebe verwendet wird. Auf der einen Seite des Gewebes werden durch eine zusätzliche Behandlung, wie Nadelstanzen oder eine Wasserstrahlbehandlung Schlaufen erzeugt, die miteinander verfangen sind. Auf der anderen Seite des Gewebes wird durch Wärmeeinwirkung eine Verfestigung erreicht. Diese Art der Erzeugung von Schlaufen ist wenig materialschonend und ermöglicht nicht, die Schlaufenweite gezielt zu bemessen. So besteht die Gefahr, daß ein Teil der Fasern zerstört wird oder daß einige Schlaufen so groß werden, daß sie keine Befestigungsfunktion mehr übernehmen können.Furthermore, EP 0 765 616 A1 describes a loop material for a hook-loop connection known in which a fabric is used. On one side of the fabric are through an additional treatment, such as needle punching or a water jet treatment Creates loops that get caught together are. On the other side of the fabric is through Exposure to solidification reached. This kind of generation of loops is not very gentle on the material and enables not to measure the loop width specifically. So there is the danger that part of the fibers will be destroyed or that some loops become so large that they have no fastening function can take over more.

Ferner ist noch aus der WO 92/20 250 ein mehrschichtiges Material bekannt, das aus einer Trägerschicht, einer Distanzschicht und einer Verhakungsschicht besteht. Die Fasern der Verhakungsschicht sind nicht als Schlaufen geformt und bilden daher nicht selbst das nötige Volumen, in das Haken zunächst eindringen müssen, um Fasern hintergreifen zu können. Vielmehr wird dieses Volumen von der Distanzschicht zur Verfügung gestellt. Ferner ist die Streckbarkeit der Verhakungsschicht in Längsrichtung kleiner als dies bei einer Schlaufenschicht der Fall wäre. Bei der beschriebenen Schichtfolge Trägerschicht - Distanzschicht - Verhakungsschicht führt dies zu einer für Sandwichmaterialien üblichen erhöhten Steifigkeit.Furthermore, WO 92/20 250 is a multi-layer material known, that of a carrier layer, a spacer layer and there is a hooking layer. The fibers of the Interlocking layers are not shaped and form as loops therefore do not put the necessary volume into the hook first have to penetrate in order to reach behind fibers. Much more this volume is available from the spacer layer posed. Furthermore, the stretchability of the interlocking layer in the longitudinal direction smaller than this with a loop layer would be the case. With the described layer sequence, carrier layer - Spacer layer - interlocking layer leads to this an increased stiffness common for sandwich materials.

Der Erfindung liegt die Aufgabe zugrunde, ein flexibles Schlaufenmaterial einer Haken-Schlaufen-Verbindung zu schaffen, das besser an die zu befestigenden textilen Trägermaterialien angepaßt ist und auch bei kleinen Kontaktflächen eine hohe Befestigungssicherheit bietet.The invention has for its object a flexible To create loop material of a hook-loop connection, the better to the textile carrier materials to be attached is adapted and even with small contact areas offers high fastening security.

Diese Aufgabe wird bei einem Schlaufenmaterial nach dem Oberbegriff des Anspruchs 1 durch die im kennzeichnenden Teil angegebenen Merkmale gelöst.This task is done with a loop material according to the generic term of claim 1 by those specified in the characterizing part Features resolved.

Der Herstellungsprozeß des erfindungsgemäßen Schlaufenmaterials geht von einer Vliesbildungstechnologie aus, so daß übliche Maschinen der Nonwoven-Industrie zur Herstellung von textilen Flächengebilden verwendet werden können. Übliche Vliese sind jedoch nicht ohne weiteres geeignet, als Schlaufenmaterial zu dienen. Dies wird bei der Erfindung erst dadurch erreicht, daß Fasern oder Filamente verwendet werden, die aufgrund ihrer geometrischen Struktur zu einer voluminösen Schicht führen und daß diese Schicht über besonders gestaltete Bondingbereiche mit der Trägerschicht verbunden ist, die ausreichend große verhakungsfähige Flächenbereiche hinterlassen. Aufgrund ihrer geometrischen Gestaltung bauschen sich die Fasern oder Filamente nämlich auf und widersetzen sich zwischen den Bondingbereichen dem Andruck an die Trägerschicht. Dadurch bleibt das Faser- oder Filamentvolumen zwischen den Bondingbereichen erhalten, wobei die Fasern oder Filamente durch die zweiseitige Verbindung mit der Trägerschicht an den Bondingbereichen automatisch zwischen diesen Verbindungen zu Schlaufen werden.The manufacturing process of the loop material according to the invention is based on a nonwoven technology, so that usual Machines of the nonwoven industry for the production of textiles Sheets can be used. Usual fleeces are not suitable as loop material to serve. This is only achieved in the invention by that fibers or filaments are used due to their geometric structure to a voluminous Lead layer and that this layer over specially designed Bonding areas is connected to the carrier layer, the leave sufficiently large areas that can be hooked. Bulge due to their geometric design the fibers or filaments namely open and resist between the bonding areas the pressure on the carrier layer. This keeps the fiber or filament volume between receive the bonding areas, the fibers or Filaments through the two-sided connection with the carrier layer at the bonding areas automatically between them Connections become loops.

Das Volumen der rautenförmig begrenzten Schlaufenkissen ermöglicht es den Haken des Verbindungselementes, in die Schicht eindringen und die Fasern oder Filamente hintergreifen zu können. Außerdem bleibt die Flexibilität des Materials erhalten.The volume of the diamond-shaped loop cushions allows it the hook of the connecting element into which Penetrate the layer and reach behind the fibers or filaments to be able to. In addition, the flexibility of the material remains receive.

Beim Thermobonding werden die Fasern oder Filamente weder in ihren freien Bereichen beschädigt noch gestreckt. Die Schlaufenlänge wird somit nicht vergrößert, so daß ein unerwünschtes Spiel zwischen ineinandergreifenden Haken und Schlaufen vermieden wird. With thermal bonding, the fibers or filaments are neither in their free areas damaged still stretched. The loop length is therefore not enlarged, so that an undesirable Game between interlocking hooks and loops is avoided.

Die schmalen linienartigen, parallel verlaufenden Bondingbereiche können durchgehend oder unterbrochen sein. Bei unterbrochenen Bondingbereichen bleibt ein größerer Teil des ursprünglichen Volumens der Faser- oder Filamentschicht erhalten. Allerdings kann bei kurzen Fasern dann eventuell ein Befestigungspunkt an der Trägerschicht fehlen. Bei durchgehenden Bondingbereichen ist dagegen die Wahrscheinlichkeit sehr groß, daß die Fasern beidseitig an der Trägerschicht befestigt sind.The narrow line-like, parallel bonding areas can be continuous or interrupted. When interrupted Bonding areas remain a larger part of the original Obtained volume of the fiber or filament layer. In the case of short fibers, however, an attachment point may then be used missing on the carrier layer. With continuous Bonding areas, on the other hand, are very likely large that the fibers attached to the carrier layer on both sides are.

Die Faserschicht kann durch ein kardiertes Gelege oder ein kardiertes Flor gebildet sein, bei dem die Fasern während des Herstellungsprozesses eine Vorzugsrichtung in Maschinenrichtung erhalten haben. Die schmalen linienartigen, parallel verlaufenden Bondingbereiche sind dann jeweils im spitzen Winkel zur Vorzugsrichtung der Fasern angeordnet. Dadurch wird sichergestellt, daß die Ausrichtung der Bondingbereiche mit großer Wahrscheinlichkeit schräg zur Ausrichtung des größten Teils der Fasern erstreckt, wodurch ein sehr hoher Anteil der Fasern beidseitig an der Trägerschicht befestigt wird. The fiber layer can be a carded scrim or a be carded pile, in which the fibers during the Manufacturing process a preferred direction in the machine direction have received. The narrow line-like, parallel then running bonding areas are each in the tip Angle to the preferred direction of the fibers arranged. Thereby ensures that the alignment of the bonding areas most likely obliquely to the orientation of the most of the fibers stretch, creating a very high Proportion of fibers attached to the carrier layer on both sides becomes.

Die Dicke des Fasergeleges oder Faserflors ist größer als 0,15 mm. Außerdem ist das Flächengewicht des Fasergeleges oder Faserflors ist größer als 8 g pro Quadratmeter. Damit ist sichergestellt, daß die Widerhaken der Stachel auch die Fasern sicher hintergreifen können.The thickness of the scrim or batt is greater than 0.15 mm. In addition, the basis weight of the fiber fabric is or fiber pile is greater than 8 g per square meter. In order to it is ensured that the barbs of the sting also the Can safely reach behind fibers.

Ferner ist die Feinheit der Fasern größer als 1,7 dtex. Damit wird eine ausreichende Festigkeit erreicht, um wenigstens 2 Öffne- und Schließzyklen zu ermöglichen.The fineness of the fibers is also greater than 1.7 dtex. In order to sufficient strength is achieved to at least 2 To enable opening and closing cycles.

Die Schnittlänge der Fasern ist wenigstens das zweifache des Größenabstandes benachbarter Verbindungslinien. Die stellt sicher, daß nahezu alle Fasern an wenigstens zwei Stellen mit anderen Fasern verbunden sind.The cutting length of the fibers is at least twice the Distance between adjacent connecting lines. That poses sure that almost all fibers have at least two points other fibers are connected.

Das Material der Fasern kann ein thermoplastisches Material, insbesondere Polypropylen oder Polyethylen sein.The material of the fibers can be a thermoplastic material, in particular polypropylene or polyethylene.

Die Schlaufenlänge innerhalb einer zwischen umgrenzenden Verbindungslinien liegenden Eingriffsfläche ist größer als 0,5 mm.The length of the loop within a connecting connecting line lying engagement surface is greater than 0.5 mm.

Die Trägerschicht kann ihrerseits mit einem zu befestigenden Material verbunden sein. Dieser Fall kommt z. B. bei Hygieneprodukten in Betracht, bei denen nur eine begrenzte Fläche zur Befestigung verwendet wird. Durch die erfindungsgemäßen Ausgestaltung des Schlaufenmaterials wird erreicht, daß auch kleine Flächenbereiche, die mit dem Schlaufenmaterial besetzt sind, eine gute Befestigungssicherheit gewährleisten.The backing layer can in turn be fastened with one Material. This case comes z. B. in hygiene products considered where only a limited area is used for attachment. By the invention Design of the loop material is achieved that too small areas covered with the loop material are, ensure good fastening security.

Weiterhin kann die Trägerschicht bedruckbar und/oder beleimbar sein.Furthermore, the carrier layer can be printed and / or glued be.

Neben Babywindeln ist das Schlaufenmaterial auch für Verschlüsse an Inkontinenz-Windeln, Bekleidung, Schutzanzügen, Verpackungen und technischen Anwendungen anwendbar.In addition to baby diapers, the loop material is also for closures on incontinence diapers, clothing, protective suits, Packaging and technical applications applicable.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung beschrieben, das in der Zeichnung dargestellt ist.An exemplary embodiment of the invention is described below, which is shown in the drawing.

Die Zeichnung zeigt eine Draufsicht auf Schlaufenmaterial, das aus einem ursprünglich unverfestigten Flor aus zufällig abgelegten Stapelfasern besteht. Die Stapelfasern haben etwa eine Länge von 40 mm. Dieser Flor wurde anschließend einem Kalandrierprozeß unterzogen, wobei an durchgehenden Verbindungslinien 10 die Fasern untereinander und mit einer Trägerschicht verbunden, d.h. thermobondiert wurden.The drawing shows a top view of loop material, that happened from an originally unconsolidated pile deposited staple fibers. The staple fibers have about a length of 40 mm. This pile then became one Calendering process, with continuous connecting lines 10 the fibers with each other and with a carrier layer connected, i.e. were thermobonded.

Dadurch ergeben sich rautenförmig begrenzte Schlaufenkissen, die als Eingriffsflächen 12 für die mit Widerhaken versehenen Dorne einer Hakenfläche dienen.This results in lozenge-shaped loop cushions, the as engagement surfaces 12 for those barbed Spikes serve as a hook surface.

Fig. 2 zeigt einen vergrößerten Querschnitt durch das Schlaufenmaterial nach Fig. 1. Auf einer Trägerschicht 14, die eine Folie, ein Gewebe oder ein Vlies sein kann, ist ein Flor aus kardierten, gekräuselten Stapelfasern 16 durch Thermobonding befestigt. Aufgrund dieser geometrischen Struktur der Fasern 16 bauschen sich diese auf und bilden ein im Vergleich zum Materialeinsatz ihrer Fasern wesentlich größeres Volumen. Trotz des Thermobonding, bei dem die Fasern zusammenschmelzen und außerdem mit der Trägerschicht verschmelzen, bleibt das Volumen zwischen den Bondingbereichen 10 weitgehend erhalten. Dort sind die Fasern 16 weiterhin aufgebauscht und bilden Schlaufen, in die Haken einer Hakenschicht einhaken können.Fig. 2 shows an enlarged cross section through the loop material 1. On a carrier layer 14, the one Foil, a fabric or a fleece can be a pile carded, crimped staple fibers 16 by thermal bonding attached. Because of this geometric structure of the fibers 16 these puff up and form a compared to the Material use of their fibers much larger volume. Despite the thermal bonding, in which the fibers melt together and also merge with the carrier layer, that remains Volume between the bonding areas 10 largely preserved. There, the fibers 16 are further puffed up and form Loops that can hook into a hook layer.
