Abstract

A felting of synthetic fibers having an embossed pattern that forms depressions in at least one surface of the felting is disclosed. The surface of the felting with depressions contains, in at least the area of the depressions, a layer of small hollow spheres that are bonded to one another and to the felting by means of a binding agent. The layer of hollow spheres fills up, at least partially, the depressions in the surface of the felting produced by embossing. This reinforces and strengthens the thinner areas of felting in the vicinity of these depressions. When the reinforced felting is applied to a shoe upper, for example, the resulting upper has improved stiffness and strength. Furthermore, the excessive penetration of adhesive into the felting, which can cause a spotty or uneven appearance of the reinforced upper, is prevented. Resistance to splitting and separating is likewise improved.

Description

Die Erfindung betrifft ein Vlies aus Kunststofffasern der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a nonwoven made of plastic fibers of the type mentioned in the preamble of claim 1.

Vliese der betreffenden Art werden häufig als Futter für Schuhe, insbesondere Sportschuhe, verwendet, deren Schaft aus Leder besteht, um dadurch das Oberleder zu verstärken, schwache Stellen im Oberleder auszugleichen und insgesamt einen besseren Stand der Schuhe zu erzielen. Ein für diesen Zweck verwendetes Vlies muss darüber hinaus wasserdampf- und luftdurchlässig sein.Nonwovens of the type in question are frequently used as linings for shoes, in particular sports shoes, the upper of which is made of leather, in order to strengthen the upper leather, to compensate for weak spots in the upper leather and to achieve a better standing of the shoes overall. A fleece used for this purpose must also be permeable to water vapor and air.

Ein bekanntes Vlies der betreffenden Art, das auf seiner Rückseite mit einem durch Wärme aktivierbaren Klebstoff versehen ist, hat den Nachteil, dass der wärmeaktivierbare Klebstoff bei seiner Verklebung unter Wärme und Druck dazu neigt, in das Vlies tief einzudringen, wodurch er für die Verklebung verlorengeht und wodurch ausserdem die Gefahr besteht, dass der Klebstoff so weit durchschlägt, insbesondere an dünnen Stellen des Vlieses, dass das Vlies dort stärker transparent ist als an dickeren Stellen, was zur Folge hat, dass der andersfarbige Untergrund, auf den das Vlies aufgeklebt ist, z. B. eine Leder- oder Kunstlederrückseite, durchscheint und insgesamt ein fleckiges oder ungleichmässiges Aussehen entsteht.A known fleece of the type in question, which is provided on the back with a heat-activatable adhesive, has the disadvantage that the heat-activatable adhesive tends to penetrate deeply into the fleece when it is bonded under heat and pressure, as a result of which it is lost for the bond and there is also the risk that the adhesive will penetrate so far, especially in thin areas of the nonwoven, that the nonwoven is more transparent there than in thicker areas, which has the consequence that the differently colored background to which the nonwoven is glued, e.g. B. a leather or synthetic leather back, shines through and creates a spotty or uneven appearance overall.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und ein Vlies der betreffenden Art zu schaffen, das in der Lage ist, bei Aufbringen auf die Rückseite von Schuhoberleder oder dergleichen eine Verstärkung des Oberleders und einen besseren Stand der Schuhe zu bewirken und schwache Stellen im Oberleder auszugleichen, ohne dass ein ungleichmässiges oder fleckiges Aussehen des Vlieses nach der Befestigung entsteht, dabei gleichzeitig flexibel, leicht, weich und wasserdampf- und luftdurchlässig ist.The invention has for its object to avoid these disadvantages and to create a fleece of the type in question, which is able to bring about a reinforcement of the upper leather and a better state of the shoes when applied to the back of upper leather or the like and weak spots to compensate in the upper leather without giving the fleece an uneven or spotty appearance after fastening, while at the same time being flexible, light, soft and permeable to water vapor and air.

Die der Erfindung zugrundeliegende Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebene Lehre gelöst.The object on which the invention is based is achieved by the teaching specified in the characterizing part of claim 1.

Die gemäss der Erfindung vorgesehene Schicht von Hohlkugeln hat insbesondere die Aufgabe, die im Bereich der in der Oberfläche des Vlieses in der Regel durch Prägeverfestigung unter Hitze und Druck gebildeten Vertiefungen zumindest teilweise auszufüllen und die im Bereich dieser Vertiefungen dünneren Vliesbereiche zu verstärken. Diese Verstärkung führt nicht nur zu der gewünschten erhöhten Festigkeit und damit zur Fähigkeit der Erhöhung der Steifigkeit bei Aufbringen z.B. auf die Innenseite eines Schuhoberleders, sondern verhindert auch ein Eindringen des Klebstoffes, insbesondere des Schmelzklebstoffes, in das Vlies und damit ein ungleichmässiges Durchscheinen einer andersfarbigen Unterlage, z. B. des Oberleders. Darüber hinaus hat sich gezeigt, dass die Spalt- und Aufribbeleigenschaften verbessert sind.The layer of hollow spheres provided according to the invention has the particular task of at least partially filling in the depressions formed in the surface of the nonwoven, as a rule by embossing under heat and pressure, and of reinforcing the nonwoven areas which are thinner in the area of these depressions. This reinforcement not only leads to the desired increased strength and thus to the ability to increase the rigidity when applied e.g. on the inside of a shoe leather, but also prevents penetration of the adhesive, in particular the hot melt adhesive, into the fleece and thus an uneven shining through of a differently colored base, e.g. B. the upper leather. In addition, it has been shown that the splitting and rubbing properties are improved.

Die Schicht von kleinen Hohlkugeln kann die Vertiefungen in der Oberfläche des Vlieses ganz oder teilweise ausfüllen. Grundsätzlich ist es im Rahmen der Erfindung durchaus möglich, auf beiden Seiten des Vlieses eine Schicht gemäss der Erfindung vorzusehen, insbesondere dann, wenn sich auch auf beiden Seiten Vertiefungen in der Oberfläche befinden. Im Bereich der erhabenen Stellen zwischen den Vertiefungen kann die Schicht von kleinen Hohlkugeln sehr dünn sein, sie kann dort sogar ganz entfallen, jedoch wird sie aus fertigungstechnischen Gründen auch dort meist vorhanden sein.The layer of small hollow spheres can completely or partially fill the depressions in the surface of the fleece. In principle, it is entirely possible within the scope of the invention to provide a layer according to the invention on both sides of the nonwoven, in particular if there are also depressions in the surface on both sides. In the area of the raised areas between the depressions, the layer of small hollow spheres can be very thin, it can even be omitted there entirely, but it will usually also be present there for manufacturing reasons.

Um die Wasserdampf- und Luftdurchlässigkeit der Schicht von kleinen Hohlkugeln zu gewährleisten, ist es zweckmässig, wenn das Bindemittel für die Hohlkugeln durchgehend Zwischenräume aufweist. Dies lässt sich in einfacher Weise durch eine entsprechend vorsichtige Dosierung des Bindemittels erreichen. Ist gemäss einer Weiterbildung der Erfindung die Schicht von kleinen Hohlkugeln mit einer Schicht von Klebstoff versehen, so weist auch dieser zweckmässigerweise Zwischenräume zu dem gleichen Zwecke auf.In order to ensure the water vapor and air permeability of the layer of small hollow spheres, it is expedient if the binder for the hollow spheres has gaps throughout. This can be achieved in a simple manner by metering the binder appropriately and carefully. If, according to a development of the invention, the layer of small hollow spheres is provided with a layer of adhesive, then this also expediently has gaps for the same purpose.

Eine besonders zweckmässige Weiterbildung der Erfindung besteht darin, dass die Hohlkugeln aus thermoplastischem Material bestehen. Dadurch ist es möglich, mittels einer heissen und glatten Walze die kleinen thermoplastischen Hohlkugeln zu verformen und so die Oberfläche des Vlieses zu glätten. Um zu vermeiden, dass dabei das Vlies selbst verformt wird, wenn es aus thermoplastischem Material besteht, ist es zweckmässig, dass der Schmelzpunkt der thermoplastischen Hohlkugeln niedriger liegt als der des Materials des Vlieses.A particularly expedient development of the invention is that the hollow spheres consist of thermoplastic material. This makes it possible to use a hot and smooth roller to deform the small thermoplastic hollow spheres and thus smooth the surface of the fleece. In order to avoid that the fleece itself is deformed when it is made of thermoplastic material, it is expedient for the melting point of the thermoplastic hollow spheres to be lower than that of the material of the fleece.

Weitere vorteilhafte Weiterbildungen und Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen und aus der nachfolgenden Beschreibung eines Ausführungsbeispiels.Further advantageous developments and details of the invention result from the subclaims and from the following description of an exemplary embodiment.

Die Zeichnung zeigt einen Teilschnitt durch ein Ausführungsbeispiel gemäss der Erfindung, bei dem ein Vlies 1 aus thermoplastischen Fasern auf beiden Oberflächen Vertiefungen 2 und 3 aufweist, die durch Heissprägung im Bereich der Vertiefungen gebildet sind, um so die thermoplastischen Fasern des Vlieses miteinander zu verkleben oder zu verschweissen. Im Bereich der Vertiefungen 2 und 3 sind also dünne Stellen 4 des Vlieses 1 gebildet.The drawing shows a partial section through an exemplary embodiment according to the invention, in which a fleece 1 made of thermoplastic fibers has depressions 2 and 3 on both surfaces, which are formed by hot stamping in the region of the depressions, so as to bond the thermoplastic fibers of the fleece to one another or to weld. Thin areas 4 of the fleece 1 are thus formed in the region of the depressions 2 and 3.

Auf der die Vertiefungen 2 aufweisenden Oberfläche des Vlieses 1 befindet sich eine Schicht von kleinen Hohlkugeln 5 aus Vinylidenchlorid-Copolymerisat, die durch ein Bindemittel 6 miteinander und mit dem Vlies 1 so verbunden sind, dass zwischen den kleinen Hohlkugeln 5 freie, durchgehende Zwischenräume gebildet sind. Die Schicht von kleinen Hohlkugeln 5 füllt die Vertiefungen 2 weitgehend aus und ist im Bereich der erhabenen Stellen 7 zwischen den Vertiefungen 2 nur sehr dünn. Auf der dem Vlies 1 abgewandten Seite der Schicht von Hohlkugeln 5 befindet sich eine Schicht 8 von Schmelzklebstoff, der ein punktförmiges Muster bildet.On the surface of the fleece 1 having the depressions 2 there is a layer of small hollow spheres 5 made of vinylidene chloride copolymer which are bonded to one another and to the fleece 1 by means of a binder 6 such that free, continuous spaces are formed between the small hollow spheres 5 . The layer of small hollow spheres 5 largely fills the depressions 2 and is only very thin in the region of the raised points 7 between the depressions 2. On the side of the layer of hollow spheres 5 facing away from the fleece 1 there is a layer 8 of hot-melt adhesive which forms a point-like pattern.
