Flachenformiges HaftverschlußteilFlat shaped fastener part
Die Erfindung betrifft ein flachenformiges Haftverschlußteil für einen Haftverschluß, bei dem lösbar miteinander korrespondierende Verschlußelemente in Eingriff bringbar sind, mit einem Grundgewebe aus Kettfäden und Schußfäden und mit mindestens einem Funktionsfaden, der das Grundge- webe teilweise durchgreift und der die Verschlußelemente ausbildet.The invention relates to a flat-shaped adhesive fastener part for an adhesive fastener, in which correspondingly mutually corresponding fastener elements can be brought into engagement, with a base fabric made of warp threads and weft threads and with at least one functional thread which partially extends through the basic fabric and which forms the fastener elements.
Gewebte Haftverschlußteile, deren Kett-, Schuß- und Funktionsfäden aus textilen Fasern, aber auch aus Kunststoff- oder Metallfasern bestehen können, sind in einer Vielzahl von Ausführungsformen auf dem Markt frei er- häitlich. Die Funktionsfäden bilden dabei im Grundgewebe aus Kett- und Schußfäden schlaufenförmige Verhakungselemente aus, sofern sie aus Mul- tifilamentfäden gebildet sind. Sind die Funktionsfäden aus Monofilamentfä- den gebildet und sofern man die dahingehend geschlossenen Schlaufen aufschneidet oder thermisch voneinander trennt, entstehen dergestalt Ver- schlußhaken, die in Eingriff bringbar sind mit einem korrespondierend ausgebildeten Flausch-Schlaufenmateriäl des anderen Verschlußteils. Sofern man bei dem Auftrennvorgang die freien Schlaufenenden thermisch behandelt, beispielsweise aufschmilzt, entstehen durch das Eigenverhalten des Kunststoffmaterials pilzförmige Verschlußköpfe als Verschlußelemente. Des weiteren besteht auch die Möglichkeit, dahingehende haken- oder pilzför- mige Verschlußelemente mit filzartigen Haftverschlußteilen unter Bildung des Haftverschlusses lösbar miteinander in Eingriff zu bringen.Woven adhesive fastener parts, the warp, weft and functional threads of which can consist of textile fibers, but also of plastic or metal fibers, are freely available on the market in a large number of embodiments. The functional threads form loop-shaped hooking elements in the base fabric from warp and weft threads, provided that they are formed from multifilament threads. If the functional threads are made of monofilament threads and if the loops which have been closed are cut open or thermally separated from one another, this results in closure hooks which can be brought into engagement with a correspondingly designed loop material of the other closure part. If the free loop ends are thermally treated, for example melted, during the opening process, mushroom-shaped closure heads are produced as closure elements by the inherent behavior of the plastic material. Furthermore, there is also the possibility of hook or mushroom to releasably bring together locking elements with felt-like adhesive fastener parts to form the adhesive fastener.
Mit den dahingehend bekannten Haftverschlußsystemen lassen sich sehr gute Schälfestigkeitswerte erreichen, d.h. es sind relativ hohe Kräfte notwendig, um die flächenförmigen korrespondierenden Haftverschlußteile, die den Haftverschluß bilden, zum Lösen der Verbindung auseinander zu ziehen. Da die Verschlußelemente der korrespondierenden Verschlußteile aber eine bestimmte Orientierung zueinander einnehmen, die statistisch gesehen regelmäßig ist, hat es sich in der Praxis gezeigt, daß nach Überwinden einer Anfangshaftschwelle der Verschluß sich doch leicht lösen läßt, weil in der jeweiligen gemeinsamen Orientierung die miteinander verhakten Verschlußelemente leicht voneinander abgleiten und den Verschluß freigeben.Very good peel strength values can be achieved with the known adhesive fastener systems, i.e. relatively high forces are required to pull apart the flat corresponding corresponding fastener parts which form the fastener to release the connection. However, since the closure elements of the corresponding closure parts have a certain orientation to one another, which is statistically regular, it has been shown in practice that after an initial adhesion threshold has been overcome, the closure can be easily released, because in the respective common orientation the interlocking closure elements slide slightly from each other and release the lock.
Um dem zu begegnen, ist in dem US-Patent 5,040,275 für einen gegossenen Haftverschlußteil bereits vorgeschlagen worden, die Verschlußelemente in sinusförmigen Bahnen anzuordnen, wobei jedes Verschlußelement aus einem U-förmigen Hakenpaar besteht, das an seinen freien Enden mit ei- nem Pilzkopf versehen ist. Ferner ist quer zur sinusförmigen Bahn zwischen den paarweise quer dazu liegenden U-förmigen Verschlußelementen ein Abstand eingehalten, so daß in den dahingehend freien Abstand die Verschlußköpfe ausweichen können, um dergestalt möglichst widerstandsfrei unter Bildung des Haftverschlusses ein korrespondierend ausgebildetes Ver- Schlußelement zwischen sich aufnehmen und verhaken zu können, beispielsweise gleichfalls in Form einer pilzartigen Hakenausgestaltung. Aufgrund des genannten sinusförmigen Verlaufs bei dem gegossenen Verschluß, bei dem die U-förmigen Hakenelemente in ein Basis-Matrix- Material eingegossen sind, ist das beschriebene rasche Abgleiten beim Öff- nen des Verschlusses entlang einer Abschälrichtung vermieden, denn die jeweilige Sinuswelle zwingt zu einem Ausweichen des korrespondierenden eingebrachten Verschlußhakens, was zu einem Hemmnis führt und mithin zu einer Erhöhung der Schälfestigkeitswerte. In einer verbesserten Ausge- staltung dieser Lösung (US 6,076,238) hat man darüber hinaus vorgesehen, die Verhakungsmuster mit den Verschlußelementen in vorgebbaren Musterbildern „chaotisch" zu gestalten; d.h. die Verschlußelemente möglichst wahllos auf dem Grundgewebe anzuordnen, um dergestalt einen vergleichbaren Effekt zu erreichen, wie mit der sinusförmigen Anordnung; allein auch der dahingehend gegossene Kunststoffverschluß läßt sich dergestalt nicht als Gewebeteil mit Kett- und Schußfäden realisieren und die Herstellung dieses bekannten Verschlusses ist aufwendig und kostenintensiv.In order to counteract this, it has already been proposed in US Pat. No. 5,040,275 for a cast adhesive fastener part to arrange the fastener elements in sinusoidal paths, each fastener element consisting of a pair of U-shaped hooks which are provided with a mushroom head at their free ends , Furthermore, a distance is maintained transversely to the sinusoidal path between the pairs of U-shaped closure elements lying transversely thereto, so that the closure heads can dodge in the free space in order to accommodate a correspondingly formed closure element between them in a manner that is as resistance-free as possible while forming the adhesive closure to get caught, for example, also in the form of a mushroom-like hook configuration. Due to the above-mentioned sinusoidal course in the cast closure, in which the U-shaped hook elements are cast in a base matrix material, the described rapid sliding when opening NEN the closure along a peeling direction avoided, because the respective sine wave forces the corresponding inserted hook to dodge, which leads to an obstacle and thus to an increase in the peel strength values. In an improved embodiment of this solution (US Pat. No. 6,076,238), provision has also been made for the interlocking patterns with the closure elements to be “chaotic” in predeterminable pattern images, ie to arrange the closure elements as randomly as possible on the base fabric in order to achieve a comparable effect in this way, as with the sinusoidal arrangement; even the plastic closure that is cast in this way cannot be realized in this way as a woven part with warp and weft threads, and the production of this known closure is complex and cost-intensive.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein flachenformiges Haftverschlußteil als gewebten Verschluß in kostengünstiger Herstellweise zu realisieren, wobei der Verschluß dennoch höhere Verhaftungswerte für die Verschlußelemente aufweist als die bisher in Webtechnik hergestellten Verschlüsse mit ihren Verschlußelementen.. Eine dahingehende Aufgabe löst ein flachenformiges Haftverschlußteil mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.Based on this prior art, the invention has for its object to realize a flat-shaped fastener part as a woven fastener in a cost-effective way of manufacturing, the fastener nevertheless has higher adhesion values for the fastener elements than the fasteners with their fastener elements previously manufactured using weaving technology solves a flat-shaped fastener part with the features of claim 1 in its entirety.
Dadurch, daß gemäß dem kennzeichnenden Teil des Patentanspruches 1 entweder die Schuß- und/oder die Kettfäden wellenförmig oder bogenförmig ausgebildet sind, ist die bisher in einer Richtung verlaufende lineare Orientierung an Verschlußelementen des Haftverschlusses vermieden und die bogenförmige Anordnung bringt einen definierten Widerstand der Au- ßer-Eingriff-Bewegung der korrespondierenden Verschlußelemente entgegen, so daß dergestalt die Haftkräfte im wesentlichen konstant und derart auch berechenbar sind und die Schälfestigkeitswerte sind gegenüber den bekannten Lösungen, die aus Geweben mit Kett- und Schußfäden aufgebaut sind, deutlich erhöht. Vorzugsweise ist dabei der jeweilige Teil des Bogens oder der Welle in der Art einer Sinus- oder Kosinuswelle ausgebildet.Characterized in that according to the characterizing part of claim 1 either the weft and / or the warp threads are wave-shaped or arcuate, the previously unidirectional linear orientation on closure elements of the adhesive fastener is avoided and the arcuate arrangement brings a defined resistance of the outer ßer-engagement movement of the corresponding closure elements so that the adhesive forces are essentially constant and thus also predictable and the peel strength values are compared to the known solutions, which are constructed from fabrics with warp and weft threads, increased significantly. The respective part of the arc or the wave is preferably designed in the manner of a sine or cosine wave.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Haftverschlußteils sind ausschließlich die Schußfäden bogenförmig im Grundgewebe verlaufend angeordnet, wobei der jeweilige Schußfaden in alternierender Reihenfolge einen Kettfaden übergreift und den in der Reihe unmittelbar nachfolgenden untergreift. Auf diese Art und Weise ist eine si- chere Befestigung der Schußfäden innerhalb der Grundgewebestruktur erreicht und die in einer Richtung linear verlaufenden Kettfäden stützen die Schußfäden im Grundgewebe entsprechend ab.In a particularly preferred embodiment of the adhesive fastener part according to the invention, only the weft threads are arranged in an arcuate manner in the base fabric, the respective weft thread overlapping a warp thread in an alternating sequence and reaching under the one immediately following in the row. In this way, a secure fastening of the weft threads within the base fabric structure is achieved and the warp threads running linearly in one direction support the weft threads in the base fabric accordingly.
Bei einer weiteren besonders bevorzugten Ausführungsform des erfin- dungsgemäßen Haftverschlußteils verläuft der jeweilige Funktionsfaden zumindest teilweise zwischen zwei benachbarten Kettfäden im Grundgewebe, wobei jeder vierte Schußfaden Untergriffen und die anderen Schußfäden übergriffen sind. Vorzugsweise ist dabei des weiteren vorgesehen, daß an der Stelle des Untergriffes des Grundgewebes der Funktionsfaden eine darüberliegende Schlaufe ausbildet und daß nachfolgend unmittelbar eine weitere Schlaufe ausgebildet ist.In a further particularly preferred embodiment of the touch-and-close fastener part according to the invention, the respective functional thread runs at least partially between two adjacent warp threads in the base fabric, with every fourth weft thread being under-gripped and the other weft threads being gripped. It is further preferably provided that the functional thread forms an overlying loop at the location of the undergrip of the base fabric and that a further loop is subsequently formed immediately.
Die dahingehenden Schlaufen können als Flauschmaterial dem Eingriff anderer Verhakungselemente dienen; sie können aber auch aufgeschnitten oder thermisch getrennt unmittelbar den Verschlußhaken bilden. Vorzugsweise ist dabei der Funktionsfaden aus einem Monofilamentfaden gebildet, der gegenüber Lösekräften entsprechend resistent ist und die benötigten Haft- und Lösewerte liefert für den zu erstellenden gewünschten Haftbandverschluß. Weitere vorteilhafte Ausführungsformen sind Gegenstand der sonstigen Unteransprüche.The loops in question can serve as a fleece material for the engagement of other interlocking elements; but they can also cut open or thermally separated directly form the locking hook. The functional thread is preferably formed from a monofilament thread which is correspondingly resistant to release forces and provides the required adhesive and release values for the desired adhesive tape closure to be produced. Further advantageous embodiments are the subject of the other subclaims.
Im folgenden wird das erfindungsgemäße Haftverschlußteil anhand eines Ausführungsbeispiels nach der Zeichnung näher erläutert. Dabei zeigen in prinzipieller und nicht maßstäblicher Darstellung dieIn the following the adhesive fastener part according to the invention is explained in more detail using an exemplary embodiment according to the drawing. In principle and not to scale, show the
Fig.1 das Gewebebild des erfindungsgemäßen Haftverschlußteils in Draufsicht;1 shows the fabric image of the fastener part according to the invention in plan view;
Fig.2 eine Seitendarstellung auf das flächige Haftverschlußteil nach der Fig. 1.2 shows a side view of the flat adhesive fastener part according to FIG. 1.
Die Fig.1 zeigt ausschnittsweise eine Draufsicht auf das erfindungsgemäße flächenförmige Haftverschlußteil. Das dahingehende Haftverschlußteil läßt sich innerhalb der Bildebene sowohl in der einen wie auch in der anderen Bildrichtung beliebig verlängern und die geometrischen Abmessungen des Flächengebildes sind abhängig von den Vorgaben der Webeinrichtung, auf der das Haftverschlußteil gefertigt wird. Das Haftverschlußteil besteht aus Kettfäden 10 und Schußfäden 12, die in Queranordnung miteinander verwebt das Grundgewebe 14 für das Haftverschlußteil bilden. Des weiteren ist das Grundgewebe 14 mit Funktionsfäden 16 in der Art von Polfäden ausgebildet. Der jeweilige Funktionsfaden 1 6 bildet dann für das flächen- förmige Haftverschlußteil die einzelnen Verschlußelemente 18 aus.1 shows a section of a plan view of the sheet-like fastener part according to the invention. The relevant adhesive fastener part can be extended as desired within the image plane in both the one and in the other image direction and the geometrical dimensions of the fabric depend on the specifications of the weaving device on which the adhesive fastener part is manufactured. The adhesive fastener part consists of warp threads 10 and weft threads 12 which, when interwoven in a transverse arrangement, form the base fabric 14 for the adhesive fastener part. Furthermore, the base fabric 14 is formed with functional threads 16 in the manner of pile threads. The respective functional thread 1 6 then forms the individual closure elements 18 for the sheet-like fastener part.
Des weiteren ist in Blickrichtung auf die Fig.1 gesehen auf ihrer Oberseite mit einem Pfeil 20 die Produktionsrichtung für das Haftverschlußteil wiedergegeben. Bei der gezeigten Anordnung nach der Fig.1 sind die jeweili- gen Schußfäden 12 in der Art einer Sinus- oder Kosinuswelle bogenförmig ausgebildet und an den Kreuzungsstellen zwischen Kettfäden 10 und Schußfäden 12 verlaufen die Kettfäden 10 parallel zur Produktionsrichtung 20 sowie parallel zueinander in geradliniger Anordnung. Bei nicht näher dargestellten Ausführungsformen des erfindungsgemäßen Haftverschlußteils wäre es darüber hinaus möglich, auch die Kettfäden 10 in der Art einer Sinus- oder Kosinuswelle bogenförmig zusätzlich oder alternativ derart auszubilden. Damit die Schußfäden 12 gemäß der Darstellung nach der Fig.1 einen bogenförmigen Verlauf erhalten, weist der hierfür vorgesehene Her- Stellwebstuhl (nicht dargestellt) einen entsprechend wellenförmig ausgebildeten Webblatteinsatz auf in der Art der benötigten Sinus- oder Kosinuswelle. Mithin läßt sich der erfindungsgemäße Haftverschluß mit hoher Produktionsgeschwindigkeit in großen Mengen zur Verfügung stellen und das sinusförmige oder kosinusförmige Webblatt (nicht dargestellt) greift quer zur Produktionsrichtung 20 zur Herstellung des bogenförmigen Schußfadenverlaufs dergestalt in das jeweilige Grundgewebe 14 ein.Furthermore, the direction of production for the adhesive fastener part is shown with an arrow 20 in the direction of view of FIG. In the arrangement shown in FIG. 1, the respective against weft threads 12 in the manner of a sine or cosine wave arcuate and at the intersections between warp threads 10 and weft threads 12, the warp threads 10 run parallel to the production direction 20 and parallel to each other in a straight line. In embodiments of the fastener part according to the invention which are not shown in detail, it would also be possible to additionally or alternatively form the warp threads 10 in the manner of a sine or cosine wave. In order for the weft threads 12 to have an arcuate course as shown in FIG. 1, the manufacturing loom (not shown) provided for this purpose has a correspondingly wave-shaped weave insert in the manner of the sine or cosine wave required. The fastener according to the invention can therefore be made available in large quantities at high production speed, and the sinusoidal or cosine-shaped reed (not shown) engages transversely to the direction of production 20 to produce the arcuate weft course in the respective base fabric 14.
Bei der Ausführungsform nach der Fig.1 sind aber nur die Schußfäden 12 bogenförmig im Grundgewebe 14 verlaufend angeordnet, wobei der jewei- lige Schußfaden 12 in alternierender Reihenfolge einen Kettfaden 10 übergreift und den in Reihe unmittelbar nachfolgenden untergreift. Der jeweilige Funktionsfaden 1 6 verläuft zumindest teilweise zwischen zwei benachbarten Kettfäden 10 im Grundgewebe 14, wobei bei der in der Fig. 1 gezeigten Anordnung in der Reihe dabei jeder vierte Schußfaden 12 untergrif- fen und die anderen Schußfäden 12 übergriffen sind. An der Stelle des jeweiligen Untergriffs des Grundgewebes 14 bildet der Funktionsfaden 16 eine darüberliegende Schlaufe 22 aus, wobei nachfolgend unmittelbar eine weitere Schlaufe 24 ausgebildet ist, so daß eine Art V-Bindung verwirklicht ist. Es sind hier aber auch andere Bindungsarten denkbar, beispielsweise das Einbinden des Funktionsfadens 1.6 in W-förmiger Art od. dgl..In the embodiment according to FIG. 1, however, only the weft threads 12 are arranged in an arc-shaped manner in the base fabric 14, the respective weft thread 12 engaging over a warp thread 10 in an alternating sequence and reaching under the one immediately following in a row. The respective functional thread 1 6 runs at least partially between two adjacent warp threads 10 in the base fabric 14, whereby in the arrangement shown in FIG. 1, every fourth weft thread 12 engages underneath and the other weft threads 12 are overlapped. At the location of the respective undergrip of the base fabric 14, the functional thread 16 forms an overlying loop 22, a further loop 24 being formed immediately thereafter so that a type of V-bond is realized is. However, other types of binding are also conceivable here, for example incorporating functional thread 1.6 in a W-shaped manner or the like.
Die genannten Schlaufen 22,24 bilden die Verschlußelemente 18 und blei- ben die Schlaufen 22,24, wie dargestellt, geschlossen, entsteht dergestalt eine Art Flausch-Haftverschlußteil, wobei haken- oder pilzartige Verschlußelemente in die dahingehenden Schlaufen 22,24 eingreifen können, um dergestalt einen lösbaren Haftverschluß zu erhalten. Es besteht aber ' auch die Möglichkeit, die Schlaufen- 22,24 aufzuschneiden, so daß derge- stalt dann ein Verschlußhaken entsteht, der mit korrespondierendem Vliesoder Flauschmaterial eines anderen, nicht näher dargestellten Verschlußteils verhakbar ist. Sofern man den Trenn- oder Schneidvorgang thermisch durchführt, und insbesondere die freien Schlaufenenden dann noch weiter erhitzt, schrumpfen die Enden zusammen und bilden dabei pilzartige Ver- schlußköpfe aus, so daß die Verschlußhaken auch pilzförmig (nicht dargestellt) sein können. Auch ist es dergestalt möglich, kombinierte Verschlüsse, also solche mit haken- und schlaufenförmigen Elementen auf einem gemeinsamen Grundgewebe 14 zu erzeugen.The loops 22, 24 mentioned form the closure elements 18 and, as shown, the loops 22, 24 remain closed, a type of fleece adhesive closure part is created in this way, hook or mushroom-like closure elements being able to engage in the loops 22, 24 in question to get a detachable fastener. But there is' also possible to cut the loop-22.24, so that derge- Stalt then a locking hook is created, that of another, the closure part is not shown is hooked with corresponding nonwoven or fleece material. If the cutting or cutting process is carried out thermally, and in particular the free ends of the loops are then heated still further, the ends shrink and form mushroom-like locking heads, so that the locking hooks can also be mushroom-shaped (not shown). It is also possible in this way to produce combined closures, that is to say those with hook-shaped and loop-shaped elements on a common base fabric 14.
Wie insbesondere die Darstellung nach der Fig.2 zeigt, kann ein einzelner Schußfaden 12 auch aus einem Schußfadenpaar bestehen oder mehrfädig sein. Dies gilt auch für die Kettfäden 10, die gemäß der Querschnitts- oder Ansichtsdarstellung nach der Fig.2 in alternierende Reihenfolge jeweils ein Paar an Schußfäden 12 übergreifen, um nachfolgend einen Untergriff dieses Schußfadenpaares 12 vorzunehmen. Der jeweilige Funktions- oder Polfaden 16 übergreift dabei unter Auslassung jeweils eines Schußfadenpaares 12 die beiden darauffolgenden Schußfadenpaare 12 in der gezeigten Reihe. Wie sich des weiteren aus den beiden Abbildungen ergibt, untergreift die jeweils weitere Schlaufe 24 für einen Untergriff des Grundgewebes 14 einen Schußfaden 12, der in Blickrichtung auf die Fig. 1 gesehen um zwei Kettfäden 10 und zwei Schußfäden 12 seitlich versetzt von der Stelle ange- ordnet ist, wo die vorangehende Schlaufe 22 ihre Lage auf dem Grundgewebe 14 hat. Auf dem Grundgewebe 14 sind also die Schlaufen der ersten Art 22 und der weiteren Art 24 versetzt zueinander angeordnet, wobei die Schlaufen der ersten Art 22 im wesentlichen geschlossene O-förmige Schlaufen ausbilden und die Schlaufen der weiteren Art 24 sind V- oder U- förmig ausgebildet. Ein sog. Rapport für einen Funktionsfaden 16 wiederholt sich in Richtung der Schußfäden 12 nach fünf Kettfäden 10. Ferner können die Fadensysteme aus textilen Fasern bestehen, bevorzugt aber sind sie aus einem Kunststoffmaterial, insbesondere Nylon oder Polypropylen - Material gebildet. Ferner besteht auch die Möglichkeit, metallische Faden- Systeme für den aufgezeigten erfindungsgemäßen Verschluß zumindest teilweise zu verwenden.As the illustration according to FIG. 2 shows in particular, a single weft thread 12 can also consist of a pair of weft threads or be multi-threaded. This also applies to the warp threads 10, which, in accordance with the cross-sectional or view representation according to FIG. 2, overlap a pair of weft threads 12 in alternating order in order to subsequently under-grip this weft thread pair 12. The respective functional thread or pile thread 16 overlaps the two subsequent weft thread pairs 12 in the row shown, omitting one pair of weft threads 12. As can also be seen from the two figures, the further loop 24 engages under a weft thread 12 for a grip under the base fabric 14, which, viewed in the direction of FIG. 1, is offset by two warp threads 10 and two weft threads 12 laterally offset from the point arranges where the preceding loop 22 has its position on the base fabric 14. On the base fabric 14, the loops of the first type 22 and the further type 24 are thus arranged offset from one another, the loops of the first type 22 forming essentially closed O-shaped loops and the loops of the further type 24 being V-shaped or U-shaped educated. A so-called repeat for a functional thread 16 is repeated in the direction of the weft threads 12 after five warp threads 10. Furthermore, the thread systems can consist of textile fibers, but they are preferably formed from a plastic material, in particular nylon or polypropylene material. Furthermore, there is also the possibility of at least partially using metallic thread systems for the closure according to the invention shown.
Durch die wellenförmige Anordnung der Schußfäden 12 ist erreicht, daß beim Abschälen und mithin beim Lösen des Verschlusses über die korre- spondierend versetzte Anordnung der Schlaufen 22,24 - auch als Hakenmaterial ausgebildet - in Abschälrichtung ein erhöhter Widerstand entgegensteht, was das Verschlußkraftverhalten begünstigt und somit hohe Haft- sowie Schälfestigkeitswerte für den Verschluß ergibt. In Abhängigkeit der Ausgestaltung des gewählten Verschlusses ist es dar- über hinaus möglich, die Haftwerte.für den Verschluß weitestgehend konstant einzustellen, so daß immer mit ein und derselben Lösekraft der Haftverschluß gelöst werden kann. The wave-shaped arrangement of the weft threads 12 means that when peeling and thus when the closure is released via the correspondingly offset arrangement of the loops 22, 24 - also designed as a hook material - there is an increased resistance in the peeling direction, which promotes the closing force behavior and thus results in high adhesive and peel strength values for the closure. Depending on the design of the selected fastener, it is also possible to set the adhesive values for the fastener as constant as possible so that the fastener can always be released with one and the same release force.
