Description

Die Erfindung betrifft ein Vlies mit verdichteten Ver­festigungsstellen oder Schweißpunkten od.dgl. und dazwischen befindlichen flauschigen oder lockeren Bereichen.The invention relates to a nonwoven with densified consolidation points or welding spots or the like. and fluffy or loose areas in between.

Derartige Vliese sind in zahlreichen Variationen bekannt. Sie werden aus Fasergebilden hergestellt, die mit Hilfe von Walzenpaaren unter Einwirkung von Wärme und/oder Lösungsmitteln an bestimmten Stellen verfestigt werden, wobei die Walzen dazu in der Regel gegenüber ihrer Ober­fläche hochstehende Noppen haben.Such nonwovens are known in numerous variations. They are produced from fiber structures which are solidified at certain points with the aid of pairs of rollers under the action of heat and / or solvents, the rollers generally having knobs which protrude from their surface.

In vielen Fällen ist dabei eine glatte Walze mit einer Walze kombiniert, die Noppen hat, so daß die eine Seite des Vlieses bei der Verfestigung einzelner Stellen vollständig von einer solchen Walze beaufschlagt wird und somit das Vlies auf dieser Seite eine gewisse Ver­festigung erfährt.In many cases, a smooth roller is combined with a roller that has knobs, so that one side of the fleece is fully acted upon by such a roller when individual points are solidified, and the fleece on this side is thus somewhat solidified.

Es wurde deshalb auch schon versucht, mit Walzenpaaren zu arbeiten, die jeweils sich gegenüberstehende Noppen haben, so daß das Vlies jeweils zwischen den Oberflächen der Noppen der beiden Walzen verfestigt werden sollte. Vor allem bei sehr großen Walzen ist es jedoch kaum möglich, eine derart präzise Fertigung und Lagerung der Walzen zu erreichen, daß die Noppen tatsächlich in der gewünschten Weise jeweils aufeinandertreffen. Darüber hinaus können elastische Verformungen der Walzen dazu führen, daß die Noppen nicht über die ganze Oberfläche gleichmäßig fest aneinander angedrückt werden, so daß nicht sichergestellt ist, daß alle gewünschten Stellen des Vlieses auch wirklich verfestigt sind. Macht man zu diesem Zweck aber die Noppenoberflächen entsprechend groß, werden die benachbarten Bereiche, die eigentlich locker und flauschig bleiben sollen, noch in gewissem Umfange beeinträchtigt und es entsteht somit wiederum ein Vlies, welches auch zwischen den Verfestigungsstellen eine gewisse Verminderung seiner Dicke erfährt.It has therefore already been attempted to work with pairs of rollers, each of which has opposing knobs, so that the fleece should be consolidated between the surfaces of the knobs of the two rollers. However, especially with very large rollers, it is hardly possible to achieve such precise manufacturing and storage of the rollers that the knobs actually meet each other in the desired manner. In addition, elastic deformations of the rollers can result in the knobs not being pressed firmly against one another uniformly over the entire surface, so that it is not ensured that all the desired locations of the nonwoven are actually solidified. If, however, the nub surfaces are made correspondingly large for this purpose, the neighboring areas, which should actually remain loose and fluffy, will still be impaired to a certain extent and this will in turn create a fleece, which will also experience a certain reduction in its thickness between the consolidation points.

Es besteht deshalb die Aufgabe, ein Vlies der eingangs erwähnten Art zu schaffen, welches einerseits in der erwünschten Weise an den vorbestimmten Stellen verfestigt ist, dazwischen aber flauschig und locker bleibt.There is therefore the task of creating a fleece of the type mentioned at the outset, which on the one hand is solidified in the desired manner at the predetermined points, but remains fluffy and loose in between.

Zur Lösung dieser Aufgabe ist das Vlies erfindungsgemäß dadurch gekennzeichnet, daß jeweils einander benachbarte Verfestigungsstellen gegeneinander höhenversetzt sind und die flauschigen Bereiche die Höhenunterschiede der Verfestigungsstellen überbrücken. Auf diese Weise ergibt sich insgeamt ein Vlies von relativ großer Dicke, das also fasrige lockere Bereiche hat, die nicht durch den Verfestigungsvorgang beeinträchtigt wurden, wobei das Vlies durch den Höhenversatz der Verfestigungsstellen unter Umständen sogar nach der Bearbeitung dicker als vor­her sein kann.To achieve this object, the fleece according to the invention is characterized in that adjacent consolidation points are offset in height from one another and the fluffy areas bridge the height differences of the consolidation points. In this way, the overall result is a fleece of relatively great thickness, which therefore has fibrous, loose areas which have not been impaired by the consolidation process, the fleece being able to be thicker than before, in some cases even after processing, due to the height offset of the consolidation points.

Besonders zweckmäßig ist es dabei, wenn die Schweißpunkte oder Verfestigungsstellen in zwei gegeneinander höhen­versetzten etwa parallelen Ebenen angeordnet sind und jeweils unmittelbar nebeneinanderliegende Verfestigungs­stellen der einen Ebene zwischen sich eine Vertiefung haben, deren Grund eine Verfestigungsstelle in der paral­lenen Ebene darstellt. Auf diese Weise ergibt sich ein Vlies definierter Dicke mit guter Stabilisierung an den Verfestigungsstellen und dennoch großer Lockerheit da­zwischen. Dabei kann die Hälfte der Anzahl der Ver­festigungsstellen in der einen Ebene und die zweite Hälfte in der anderen Ebene liegen. Erreicht werden kann dies praktisch mit zwei das Vlies bearbeitenden Walzen, deren Noppen gegeneinander derart versetzt sind, daß die Noppen der einen Walze in die Zwischenräume zwischen den Noppen der anderen Walzen passen und eingreifen, dabei aber zwischen ihren Flanken einen Abstand einhalten, innerhalb welchem das Vlies unbearbeitet bleibt.It is particularly expedient if the welding points or consolidation points are arranged in two approximately parallel planes offset from one another in height in each case directly adjacent consolidation points of one level have a depression between them, the bottom of which represents a consolidation point in the parallel plane. In this way, a fleece of defined thickness is obtained with good stabilization at the consolidation points and still great looseness in between. Half of the number of consolidation points can be in one level and the second half in the other level. This can be achieved practically with two fleece-processing rollers, the knobs of which are offset from one another in such a way that the knobs of one roller fit and engage in the spaces between the knobs of the other rollers, but maintain a distance between their flanks within which the Fleece remains unprocessed.

Ein weiteres vorteilhaftes Merkmal des erfindungsgemäßen Vlieses kann darin bestehen, daß die Ausdehnung der Fläche der Verfestigungsstellen kleiner als der in einer Ebene von Verfestigungsstellen umgrenzte Zwischenraum ist und die flauschigen Bereiche können von den Verfestigungs­stellen der einen Ebene zu denen der anderen Ebene schräg verlaufen. Die Nachgiebigkeit eines solchen Vlieses nach seiner Fertigstellung quer zu seiner Haupt-Oberfläche wird somit durch diese schräg verlaufende nicht ver­festigten Bereiche erheblich gefördert, weil nicht nur die ursprünglich quer zu den Fasern verlaufende Abmessung als Verdichtungsbereich zur Verfügung steht, sondern auch der Abstand der in verschiedenen Ebenen angeordneten Verfestigungsstellen.Another advantageous feature of the nonwoven according to the invention can be that the extent of the area of the consolidation points is smaller than the space delimited in one level by consolidation points and the fluffy areas can run obliquely from the consolidation points on one level to those on the other level. The flexibility of such a fleece after its completion across its main surface is thus significantly promoted by these inclined non-consolidated areas, because not only the dimension originally running across the fibers is available as a compression area, but also the distance between the different areas Leveling points arranged.

Damit ein solches Vlies bezüglich seiner Formgebung ge­nügend stabil ist, ist es vorteilhaft, wenn die Schweiß­punkte oder Verfestigungsstellen jeweils eine Fort­setzung oder einen Übergang in die schrägliegenden flauschigen Bereiche haben und jeweils etwa kappenförmig ausgebildet sind. Dies bedeutet, daß also jeweils die allerletzten Enden der flauschigen Bereiche noch in ihrem schrägen Verlauf bereits verfestigt sind, was sich sehr einfach realisieren läßt, wenn die Noppen entsprechend stark beheizt sind, so daß eine Verfestigung auch noch etwas jenseits des Randes der Noppenoberfläche bewirkt wird, wo das Vlies immer noch relativ fest an einer solchen Noppe anliegt.So that such a fleece is sufficiently stable with regard to its shape, it is advantageous if the welding points or consolidation points each have a continuation or a transition into the oblique one have fluffy areas and are each approximately cap-shaped. This means that the very last ends of the fluffy areas are already solidified in their oblique course, which can be realized very easily if the knobs are heated appropriately, so that solidification is also effected somewhat beyond the edge of the knob surface where the fleece is still relatively tight against such a knob.

Vor allem bei Kombination der vorbeschriebenen Merkmale und Maßnahmen ergibt sich ein Vlies, welches eine größere Dicke erhalten kann, als wenn es zwischen sich berühren­den Noppen verfestigt würde oder die Verfestigung zwischen einer glatten Walze und einer solchen mit Noppen erfolgen würde. Durch die Verlegung der Verfestigungsstellen je­weils in zwei verschiedene Höhenlagen ergibt sich gleich­zeitig eine relativ feste und widerstandfähige äußerste Oberfläche eines solchen Vlieses, gegenüber welcher die lockeren und flauschigen und saugfähigen Bereiche etwas nach innen versetzt sind, was auch der Lagerfähigkeit und dem Transport sowie der Lebensdauer eines solchen Vlieses zugute kommte.A combination of the features and measures described above results in a nonwoven which can have a greater thickness than if it were consolidated between touching knobs or if the bond between a smooth roller and one with knobs would take place. By laying the consolidation points at two different altitudes, a relatively firm and resilient outermost surface of such a fleece results at the same time, compared to which the loose and fluffy and absorbent areas are offset somewhat inward, which also affects the shelf life and transport as well as the service life of a such fleece benefited.

Nachstehend ist die Erfindung mit ihren ihr als wesent­lich zugehörenden Einzelheiten anhand der Zeichnung noch näher beschrieben.The invention is described in more detail below with its details that are essential to it, using the drawing.

Es zeigt in schematisierter Darstellung:

  • Fig. 1 einen Längsschnitt eines Teiles des Berühr­bereiches zweier mit gegensinnig angeordne­ten Noppen versehener Walzen und einem da­zwischen befindlichen Vlies, welches in unterschiedlichen Höhenlagen Verfestigungs­stellen erhält, während die dazwischen befindlichen Bereich locker und flauschig bleiben,
  • Fig. 2 ein erfindungsgemäßes Vlies nach seiner Fertigstellung und
  • Fig. 3 ein Vlies, welches nach herkömmlicher Methode gefertigt wurde.
It shows in a schematic representation:
  • Fig. 1 shows a longitudinal section of part of the contact area of two rollers provided with oppositely arranged knobs and a fleece located between them, which receives consolidation points at different altitudes, while the in between area remains loose and fluffy,
  • Fig. 2 shows a fleece according to the invention after its completion and
  • Fig. 3 is a fleece, which was manufactured by a conventional method.

Ein Vlies 1 ist mit verdichteten Befestigungsstellen 2 oder Schweißpunkten und dazwischen befindlichen flauschigen oder lockeren Bereichen 3 versehen. Während bei konventionell gefertigten Vliesen gemäß Fig. 3 die Verfestigungsstellen 2 und die flauschigen Bereiche 3 praktisch in einer Ebene liegen, so daß ein solches Vlies nach seiner Fertigstellung relativ dünn ist, ist bei dem erfindungsgemäßen Vlies gemäß Fig. 3 vorgesehen, daß jeweils einander benachbarte Verfestigungsstellen 2 gegeneinander höhenversetzt sind und die flauschigen Bereiche 3 die Höhenunterschiede dieser Verfestigungsstellen 2 überbrücken. Beim Vergleich der Figuren 2 und 3 erkennt man deutlich, daß dadurch ein Vlies 1 von beachtlicher Dicke gefertigt werden kann, wel­ches also auch eine entsprechend gute Polster- oder Saug­wirkung haben kann. Gleichzeitig liegen aber die Ver­festigungsstellen 2 jeweils an den einander gegenüberlie­genden Oberseiten und schützen somit das Vlies 1.A fleece 1 is provided with compressed fastening points 2 or welding spots and fluffy or loose areas 3 located between them. 3, the consolidation points 2 and the fluffy areas 3 lie practically in one plane, so that such a nonwoven is relatively thin after its completion, the nonwoven according to the invention according to FIG. 3 provides that adjacent to each other Solidification points 2 are offset in height from each other and the fluffy areas 3 bridge the height differences of these consolidation points 2. A comparison of FIGS. 2 and 3 clearly shows that a fleece 1 of considerable thickness can thereby be produced, which can therefore also have a correspondingly good cushioning or suction effect. At the same time, however, the consolidation points 2 each lie on the opposite top sides and thus protect the fleece 1.

Fig. 2 macht dabei deutlich, daß die Schweißpunkte oder Verfestigungsstellen 2 in zwei gegeneinander höhenver­setzten, etwa parallelen Ebenen angeordnet sind. Jeweils nebeneinanderliegende Verfestigungsstellen 2 der einen Ebene haben dabei zwischen sich eine Vertiefung 4, deren Grund eine Verfestigungsstelle 2 in der parallelen Ebene darstellt oder aufweist. Auf diese Weise ergibt sich, daß die Hälfte der Anzahl der Verfestigungsstellen 2 in der einen Ebene und die zweite Hälfte in der anderen Ebene liegt.Fig. 2 makes it clear that the welding points or consolidation points 2 are arranged in two mutually vertically offset, approximately parallel planes. In each case adjacent consolidation points 2 of one level have between them a depression 4, the bottom of which represents or has a consolidation point 2 in the parallel plane. In this way it follows that half of the number of consolidation points 2 in the one level and the second half is on the other level.

Die Ausdehnung der Fläche der Verfestigungsstellen 2 ist dabei kleiner als der in einer Ebene jeweils von solchen Verfestigungsstellen 2 umgrenzte Zwischenraum und die flauschigen Bereiche 3 verlaufen von den Verfestigungs­stellen 2 der einen Ebene zu denen der anderen Ebene schräg. Auf diese Weise können sie wesentlich größere Ver­formungswege aufnehmen, so daß also die Weichheit und Geschmeidigkeit des erfindungsgemäßen Vlieses 1 gegenüber einem konventionellen Vlies gemäß Fig. 3 erheblich er­höht ist.The extent of the area of the consolidation points 2 is smaller than the space delimited in each plane by such consolidation points 2 and the fluffy areas 3 run obliquely from the consolidation points 2 on one level to those on the other level. In this way, they can absorb much larger deformation paths, so that the softness and suppleness of the fleece 1 according to the invention is considerably increased compared to a conventional fleece according to FIG. 3.

In Fig. 1, wo die Entstehung dieser höhenversetzten Ver­fetigungsstellen 2 jeweils zwischen Noppen 5 und 6 und diesen jeweils gegenüberliegenden Walzenflächen 7 darge­stellt sind, erkennt man ferner, daß die Verfestigungs­stellen 3 jeweils eine Fortsetzung oder einen Übergang 3a in die schrägliegenden flauschigen Bereiche 3 haben und dadurch jeweils etwa kappenförmig ausgebildet sind. Sie haben dadurch eine relativ gute Steifigkeit und können dazu beitragen, daß die in Fig. 2 dargestellte Form des Vlieses relativ beständig ist.In Fig. 1, where the emergence of these vertically offset fastening points 2 are each shown between knobs 5 and 6 and these opposite roller surfaces 7, it can also be seen that the hardening points 3 each have a continuation or a transition 3a into the inclined fluffy areas 3 and are thereby each approximately cap-shaped. As a result, they have a relatively good rigidity and can contribute to the shape of the fleece shown in FIG. 2 being relatively stable.

Ein weiterer Vorteil dieser Anordnung und Form des Vlieses besteht noch darin, daß bei einem Druck etwa senkrecht zu den Ebenen, in denen die Verfestigungsstellen 2 liegen, die lockeren und flauschigen Bereiche 3 sogar gestaucht und in ihrer eigentlichen Dicke evtl. noch vergrößert werden, so daß ihre Saugfähigkeit sogar noch etwas zunehmen kann.Another advantage of this arrangement and shape of the fleece is that at a pressure approximately perpendicular to the planes in which the consolidation points 2 are located, the loose and fluffy areas 3 are even compressed and possibly increased in their actual thickness, so that their absorbency can even increase somewhat.

Ein weiterer Vorteil der gegeneinander höhenversetzten Ver­festigungs- oder Schweißstellen 2 und der dazwischen befind­lichen flauschigen Bereiche besteht noch darin, daß dieses Vlies in einem einzigen Arbeitsgang, nämlich bei seiner Ver­festigung und punktuellen Verschweißung in diese Form ge­bracht werden kann und eine nachträgliche Prägung des Vlieses vermieden wird, bei welcher die Gefahr bestünde, daß gerade flauschige Bereiche verpresst und verknickt werden könnten und somit ihr Volumen verlieren würden.Another advantage of the stiffening or welding points 2 offset from one another in height and the fluffy areas located between them is that this Fleece can be brought into this form in a single operation, namely during its solidification and spot welding, and subsequent embossing of the fleece is avoided, in which there is a risk that fluffy areas in particular could be pressed and buckled and would thus lose their volume.

Insbesondere bei kappenförmiger Ausbildung der Schweiß- oder Verfestigungsstellen 2 ergibt sich dabei ein Vlies, welches zusätzlich zu seinen flauschigen und federnden Eigenschaften und seinem großen Gesamtvolumen auch noch besonders stabil ist.Particularly in the case of a cap-shaped formation of the welding or hardening points 2, this results in a fleece which, in addition to its fluffy and springy properties and its large overall volume, is also particularly stable.
