Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines wasserdichten, atmungsaktiven Schuhwerks sowie ein wasserdichtes und atmungsaktives Schuhwerk.The invention relates to a method for producing a waterproof, breathable footwear and a waterproof and breathable footwear.

Ein wasserdichtes, atmungsaktives Schuhwerk besteht üblicherweise aus einem Außenschaft, der luft- und damit wasserdurchlässig ist, z.B. aus Leder oder aus einem textilen Material, einem Innenschaft, der ein Futtermaterial und eine wasserdichte, wasserdampfdurchlässige Funktionsschicht enthält, eine Brandsohle, die entlang ihres äußeren Randes mit dem Innenschaft und dem Außenschaft durch eine Naht verbunden ist und eine Laufsohle, die an die Brandsohle und das damit verbundene Außen- bzw. Innenschaftende so angespritzt ist, dass sowohl die Naht, die Brandsohle, Innen- und Außenschaft miteinander verbindet, als auch das Schaftende selbst von dem Laufsohlenmaterial umschlossen wird.A waterproof, breathable footwear usually consists of an outer shaft that is air and thus water permeable, e.g. of leather or of a textile material, an inner shaft containing a lining material and a waterproof, water vapor permeable functional layer, an insole which is connected along its outer edge to the inner shaft and the outer shaft by a seam and an outsole attached to the insole and the associated outer or inner end is molded so that both the seam, the insole, inner and outer shank connects to each other, as well as the shaft end itself is enclosed by the outsole material.

Ein kritisches Merkmal eines solchen wasserdichten, atmungsaktiven Schuhwerkes ist eine vollständige und dauerhafte Abdichtung der Nähte, die Teile des Innenschaftes, der eine wasserdampfdurchlässige Funktionsschicht enthält, miteinander verbinden, bzw. der Nähte die Innenschaft mit Außenschaft und/oder Brandsohle miteinander verbinden.A critical feature of such a waterproof, breathable footwear is a complete and permanent sealing of the seams, the parts of the inner shaft, which contains a water-vapor-permeable functional layer connect together or the seams connect the inner shaft with outer shaft and / or insole.

Eine Naht, die Brandsohle, Innen- und Außenschaft miteinander verbindet, ist zwar von der angespritzten Laufsohle wasserdicht umschlossen, doch hat sich gezeigt, dass der für derartige Schuhe verwendete Außenschaft, der aus Leder oder aus einem textilen Material bestehen kann, Wasser leitet. Dadurch kann Wasser im Außenschaft oder durch den Außenschaft hindurch auf der dem Innenschaft zugewandten Seite bis zum unteren Ende des Schaftes zu der Naht, die Brandsohle, Innen- und Außenschaft miteinander verbindet, vordringen und durch die durch die Naht erzeugten Nahtlöcher in der Funktionsschicht zum Futterstoff des Innenschaftes, d.h. in das Schuhinnere gelangen.Although a seam connecting the insole, inner and outer sheath is waterproofed by the molded outsole, it has been found that the outer sheath used for such shoes, which may be made of leather or of a textile material, conducts water. Thereby, water in the outer shaft or through the outer shaft on the side facing the inner shaft to the lower end of the shaft to the seam, the insole, inner and outer shank connects together, and penetrate through the seam holes created in the functional layer to the lining fabric of the inner shaft, ie get into the shoe interior.

EP 1 743 536 offenbart ein Schuhwerk, welches eine wasserdichte, wasserdampfdurchlässige Funktionsschicht umfasst, wobei hier die Verbindungen, die die Funktionsschicht betreffen, als Naht ausgeführt sind. Eine Abdichtung des Schuhwerkes entlang der Nahtstelle wird erreicht, indem im Bereich der vorgesehenen Naht zwischen die zu verbindenden Teile ein Band gelegt wird, welches nach dem Vernähen unter Hitzeeinwirkung zum Schmelzen gebracht wird und so die von der Naht erzeugten Öffnungen abdichtet. EP 1 743 536 discloses a footwear which comprises a waterproof, water-vapor-permeable functional layer, in which case the compounds which relate to the functional layer are designed as seams. A sealing of the footwear along the seam is achieved by laying a band in the region of the intended seam between the parts to be joined, which is melted after sewing under heat and thus seals the openings produced by the seam.

Bei diesem Schuhwerk sind die Nähte durch das geschmolzene Band zwar zuverlässig abgedichtet, aber insbesondere bei der Naht die Außen- und Innenschaft und gegebenenfalls auch die Brandsohle verbindet, kann immer noch Feuchtigkeit in den Außenschaft eindringen. Außerdem ist die Verarbeitung des in EP 1 743 536 offenbarten Schuhwerkes relativ aufwändig, da beim Nähen ständig nachgefasst werden muss, damit das schmelzbare Band in der gewünschten Position verbleibt.In this footwear, the seams are reliably sealed by the molten tape, but especially in the seam, the outer and inner shank and possibly also the insole connects, moisture can still penetrate into the outer shaft. In addition, the processing of in EP 1 743 536 revealed footwear relatively complex, since during sewing must be constantly followed so that the fusible band remains in the desired position.

Dokumente EP0464800 , WO9300837 und WO0024280 offenbaren wasserdichte, atmungsaktive Schuhwerke und ihre Herstellungsverfahren unter Verwendung von thermoplastischen Materialien und Klebstoffen.Documents EP0464800 . WO9300837 and WO0024280 disclose waterproof, breathable footwear and its manufacturing processes using thermoplastic materials and adhesives.

Aufgabe der vorliegenden Erfindung ist es daher, ein weiter verbessertes Verfahren zur Herstellung eines wasserdichten, atmungsaktiven Schuhwerkes sowie ein wasserdichtes, atmungsaktives Schuhwerk zur Verfügung zu stellen.The object of the present invention is therefore to provide a further improved process for producing a waterproof, breathable footwear and a waterproof, breathable footwear.

Diese Aufgabe wird gelöst durch ein Verfahren zur Herstellung eines wasserdichten, atmungsaktiven Schuhwerkes, wobei das Schuhwerk einen Außenschaft mit einer Innenseite, einer Außenseite und einem unteren Ende und einen Innenschaft mit einem unteren Ende, eine Brandsohle mit einer umlaufenden Außenkante sowie eine Laufsohle umfasst, dadurch gekennzeichnet, dass entlang des unteren Endes des Außenschaftes ein Band aus einem thermoplastischen Material um das Ende des Außenschaftes gelegt wird, so dass sich das Band aus einem thermoplastischen Material von der Außenseite des Außenschaftes über das untere Ende des Außenschaftes bis zur Innenseite des Außenschaftes erstreckt,
dass das Band aus einem thermoplastischen Material am Außenschaft fixiert wird und der Innenschaft mit dem Band aus einem thermoplastischen Material durch eine Naht verbunden wird und dass nach dem Vernähen das Band aus einem thermoplastischen Material zumindest im Bereich der Naht zum Schmelzen gebracht wird.This object is achieved by a method for producing a waterproof, breathable footwear, wherein the footwear comprises an outer shaft having an inner side, an outer side and a lower end and an inner shaft with a lower end, an insole with a circumferential outer edge and an outsole characterized in that along the lower end of the outer shaft a band of thermoplastic material is placed around the end of the outer shaft so that the band of thermoplastic material extends from the outer side of the outer shaft to the lower end of the outer shaft to the inner side of the outer shaft,
that the band of a thermoplastic material is fixed to the outer shaft and the inner shaft is connected to the band of a thermoplastic material by a seam and that after sewing, the band of a thermoplastic material is melted at least in the region of the seam.

Durch das erfindungsgemäße Verfahren wird einerseits eine doppelte Abdichtung des unteren Schuhbereiches erzielt, da das Band aus einem thermoplastischen Material auf beiden Seiten des Außenschaftes vorliegt und andererseits wird eine schnelleres Verarbeiten des Schuhes ermöglicht, da das Band bereits am Außenschaft fixiert ist und ein Nachfassen des Bandes beim Nähen entfällt.By the method according to the invention a double sealing of the lower shoe area is achieved on the one hand, since the band is made of a thermoplastic material on both sides of the outer shaft and on the other hand, a faster processing of the shoe is made possible, since the band is already fixed to the outer shaft and a follow-up of the tape when sewing is omitted.

Unter dem unteren Ende des Außenschaftes, bzw. dem unteren Innenschaftes ist das dem Sohlenbereich zugewandte Ende zu verstehen.Under the lower end of the outer shaft, or the lower inner shaft is to be understood the sole area facing the end.

Unter einer Naht im Sinne der Erfindung ist eine Verbindung von Flächengebilden unter Verwendung eines Fadens zu verstehen.Under a seam according to the invention is a compound of fabrics using a thread to understand.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens weist der Innenschaft an der dem Außenschaft zugewandten Seite eine wasserdichte, wasserdampfdurchlässige Funktionsschicht auf. Besonders bevorzugt umfasst der Innenschaft ein Futter und eine wasserdichte, wasserdampfdurchlässige Funktionsschicht, wobei die wasserdichte, wasserdampfdurchlässige Funktionsschicht mit dem Futter ein Laminat bildet.
In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens weist der Außenschaft an der Innenseite, d.h. an der dem Innenschaft zugewandten Seite, eine wasserdichte wasserdampfdurchlässige Funktionsschicht auf.In a preferred embodiment of the method according to the invention, the inner shaft has a watertight, water vapor permeable functional layer on the side facing the outer shaft. Particularly preferably, the inner shaft comprises a lining and a waterproof, water vapor permeable functional layer, wherein the waterproof, water vapor permeable functional layer forms a laminate with the lining.
In a further preferred embodiment of the method according to the invention, the outer shaft has on the inner side, ie on the side facing the inner shaft, a watertight, water-vapor-permeable functional layer.

Die Funktionsschicht erstreckt sich bevorzugt bis zum unteren Innenschaftende, wenn der Innenschaft die Funktionsschicht aufweist und bis zum unteren Außenschaftende, wenn der Außenschaft die Funktionsschicht aufweist.The functional layer preferably extends to the lower inner shaft end when the inner shaft has the functional layer and to the lower outer shaft end when the outer shaft has the functional layer.

Das Band aus einem thermoplastischen Material wird um das untere Ende des Außenschaftes herumgelegt, so dass das untere Außenschaftende durch das Band eingefasst wird. Das um das Außenschaftende herumgelegte Band wird am Außenschaft bevorzugt durch eine Naht fixiert, wobei dadurch, dass das Band um das Außenschaftende herumgelegt ist, die Naht das Band an der Außenseite des Außenschaftes, den Außenschaft und das Band an der Innenseite des Außenschaftes durchdringt. Diese Art der Fixierung ist am besten geeignet, um ein Verrutschen des Bandes während der Schuhverarbeitung und dadurch verursachtes ständiges Nachfassen von Schaft und Band zu vermeiden.The band of thermoplastic material is wrapped around the lower end of the outer shaft so that the lower outer shaft end is bordered by the band. The band wrapped around the outer shaft end is preferably fixed to the outer shaft by a suture, with the suture penetrating the band on the outer side of the outer shaft, the outer shaft and the band on the inner side of the outer shaft, by laying the band around the outer shaft end. This type of fixation is best suited to avoid slippage of the band during shoe processing and thereby caused continuous re-grasping of the shaft and band.

Das Band kann das untere Außenschaftende derart einfassen, dass das Band am unteren Außenschaftende anliegt und der Außenschaft lediglich geringfügig um die Dicke des Bandes verlängert ist. In dieser bevorzugten Ausführungsform durchdringt die Naht, die das Futter mit dem Band aus einem thermoplastischen Material verbindet, das Band an der Außenseite des Außenschaftes, den Außenschaft, das Band an der Innenseite des Außenschaftes und das Futter.The band may surround the lower outer end of the shaft such that the band abuts the lower outer shaft end and the outer shaft is extended only slightly by the thickness of the band. In this preferred embodiment, the seam which penetrates the liner with the thermoplastic band penetrates Material connects, the band on the outside of the outer shaft, the outer shaft, the band on the inside of the outer shaft and the lining.

Das Band kann allerdings auch so um das untere Außenschaftende herumgelegt werden, dass sich das Band zwar weiterhin von der Außenseite des Außenschaftes über das untere Ende des Außenschaftes bis zur Innenseite des Außenschaftes erstreckt, aber das Band zum Rand des unteren Außenschaftendes beabstandet ist und so eine Außenschaftverlängerung bildet. In dieser bevorzugten Ausführungsform durchdringt die Naht, die den Innenschaft mit dem Band aus einem thermoplastischen Material verbindet, nur das Band und den Innenschaft und nicht den Außenschaft.However, the band may be wrapped around the lower outer shaft end so that the band continues to extend from the outer side of the outer shaft to the lower end of the outer shaft to the inner side of the outer shaft, but the band is spaced from the edge of the lower outer shaft end, and so on Exterior shaft extension forms. In this preferred embodiment, the seam connecting the inner shaft to the thermoplastic material band penetrates only the band and the inner shaft and not the outer shaft.

Als Band können die dem Fachmann bekannten Nahtabdichtungsbänder verwendet werden, die beispielsweise bei Bekleidung verwendet und durch Aufbügeln auf die Naht angebracht werden können. Diese Bänder weisen eine Schmelztemperatur im Bereich von 120°C bis 150 °C auf. Durch die bevorzugte Verwendung eines niedrigschmelzenden Materials mit einer Schmelztemperatur im Bereich von 60 bis 85 °C ist eine Abdichtung der Nähte besonders einfach zu erreichen, auch wenn das Band zwischen den durch die Naht zu verbindenden Teilen vorliegt. Durch die niedrigen Schmelztemperatur im Bereich von 60°C bis 85°C ist ein Schmelzen des Bandes und eine Abdichtung der Naht insbesondere auch an schlecht zugänglichen Stellen gewährleistet.
Das Bandmaterial mit einer Schmelztemperatur von 60°C bis 85°C wird ausgewählt aus der Gruppe, bestehend aus Copolyamide, Polyurethane, Copolymere aus Polyurethan, olefinische Copolymere, beispielsweise Ethylenterpolymer, Copolymere aus Acrylaten und Ethylenvinylacetat-terpolymer.As a band, the seam sealing tapes known to those skilled in the art can be used, which can be used for example in clothing and can be applied to the seam by ironing. These tapes have a melting temperature in the range of 120 ° C to 150 ° C. By the preferred use of a low melting point material having a melting temperature in the range of 60 to 85 ° C, sealing of the seams is particularly easy to achieve, even when the tape is present between the parts to be joined by the seam. Due to the low melting temperature in the range of 60 ° C to 85 ° C, a melting of the tape and a seal of the seam is ensured, especially in poorly accessible places.
The ribbon material having a melting temperature of 60 ° C to 85 ° C is selected from the group consisting of copolyamides, polyurethanes, copolymers of polyurethane, olefinic copolymers, for example, ethylene terpolymer, copolymers of acrylates and ethylene vinyl acetate terpolymer.

Das für das erfindungsgemäße Verfahren eingesetzte Band ist bevorzugt ein Film oder ein textiles Flächengebilde, z.B. ein Vlies, Gewebe oder Gewirke oder Kombinationen davon.The strip used for the method according to the invention is preferably a film or a textile fabric, for example a nonwoven, woven or knitted fabric or combinations thereof.

Bevorzugt ist das Band an mindestens einer Seite mit einer bei Raumtemperatur klebrigen Schicht versehen ist, so dass eine Vorfixierung möglich ist.Preferably, the tape is provided on at least one side with a sticky at room temperature layer, so that a prefixing is possible.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens ragt das untere Ende des Innenschaftes über das untere Ende des Außenschaftes hinaus und Innenschaft und Brandsohle werden durch eine Naht verbunden, wobei die Naht Innenschaft und Brandsohle durchdringt. Besonders bevorzugt ist diese Naht als Strobelnaht ausgeführt.In a further preferred embodiment of the method according to the invention, the lower end of the inner shaft protrudes beyond the lower end of the outer shaft and inner shaft and insole are connected by a seam, wherein the seam penetrates the inner shaft and insole. Particularly preferably, this seam is designed as a stitching seam.

In einer weiteren bevorzugten Ausführungsform verbindet die Naht, die das Band aus einem thermoplastischen Material und den Innenschaft verbindet, auch die Brandsohle mit dem Band und dem Innenschaft, d.h. diese Naht durchdringt das Band aus einem thermoplastischen Material, den Innenschaft und die Brandsohle.In a further preferred embodiment, the seam connecting the band of thermoplastic material and the inner shaft also connects the insole with the band and the inner shaft, i. this seam penetrates the band of thermoplastic material, the inner shaft and the insole.

Des weiteren ist es bevorzugt, dass das untere Ende des Außenschaftes, das untere Ende des Innenschaftes und die Brandsohle durch eine Naht verbunden werden, wobei die Naht das Band an der Außenseite des Außenschaftes, den Außenschaft, das Band an der Innenseite des Außenschaftes, den Innenschaft und die Brandsohle durchdringt. Besonders bevorzugt ist diese Naht als Strobelnaht ausgeführt.Furthermore, it is preferable that the lower end of the outer shaft, the lower end of the inner shaft and the insole are connected by a seam, wherein the seam of the band on the outer side of the outer shaft, the outer shaft, the band on the inside of the outer shaft, the Inner shaft and the insole penetrates. Particularly preferably, this seam is designed as a stitching seam.

Nach Vernähen des Außenschaftes, des Innenschaftes und der Brandsohle, wird auf die Naht Hitze aufgebracht, wonach das Band schmilzt und die von der Naht erzeugten Öffnungen abdichtet.After sewing on the outer shaft, the inner shaft and the insole, heat is applied to the seam, after which the band melts and seals the openings created by the seam.

Die Laufsohle kann dann angeklebt oder angespritzt werden. Bei Schuhen mit angespritzter Sohle reicht die Hitze der Schmelze, die nach dem Anspritzen das Sohlenmaterial bildet, aus, um das Band zum Schmelzen zu bringen, wodurch die durch die Naht entstandenen Öffnungen abgedichtet werden.The outsole can then be glued or molded. For molded sole shoes, the heat of the melt, which forms the sole material after injection, is sufficient to melt the tape, thereby sealing the apertures formed by the seam.

Die erfindungsgemäße Aufgabe wird ebenfalls gelöst durch ein Verfahren zur Herstellung eines wasserdichten, atmungsaktiven Schuhwerkes, wobei das Schuhwerk einen Außenschaft mit einem unteren Ende, einer Innenseite und einer Außenseite und einen Innenschaft mit einem unteren Ende, eine Brandsohle mit einer umlaufenden Außenkante sowie eine Laufsohle umfasst, wobei das untere Außenschaftende über das untere Innenschaftende hinausragt, dadurch gekennzeichnet,
dass entlang des unteren Endes des Außenschaftes ein Band aus einem thermoplastischen Material um das Ende des Außenschaftes gelegt wird, so dass sich das Band aus einem thermoplastischen Material von der Außenseite des Außenschaftes über das untere Ende des Außenschaftes bis zur Innenseite des Außenschaftes erstreckt, wobei sich das Band auf der Innenseite des Außenschaftes mindestens bis zum unteren Innenschaftende erstreckt,
dass das Band aus einem thermoplastischen Material am Außenschaft fixiert wird und anschließend der Außenschaft und der Innenschaft um die Brandsohleaußenkante gelegt werden, so dass das untere Außenschaftende und das untere Innenschaftende an der Brandsohlenunterseite vorliegen und dass das Band aus einem thermoplastischen Material zum Schmelzen gebracht wird.The object according to the invention is also achieved by a method for producing a waterproof, breathable footwear, wherein the footwear comprises an outer shaft with a lower end, an inner side and an outer side and an inner shaft with a lower end, an insole with a peripheral outer edge and an outsole , wherein the lower outer end of the shaft protrudes beyond the lower inner end of the shaft, characterized
a band of a thermoplastic material is placed around the end of the outer shaft along the lower end of the outer shaft so that the band of thermoplastic material extends from the outer side of the outer shaft to the lower end of the outer shaft to the inner side of the outer shaft the band extends on the inside of the outer shaft at least to the lower inner end of the shaft,
that the band of thermoplastic material is fixed to the outer shaft and then the outer shaft and the inner shaft are placed around the insole outer edge, so that the lower outer end and the lower inner end are on the insole bottom and that the band is melted from a thermoplastic material.

Auch dieses Verfahren zeichnet sich dadurch aus, dass das untere Außenschaftende durch eine schmelzbares Band eingefasst und so eine doppelte Abdichtung des unteren Außenschaftendes erreicht wird. Der oftmals wasserleitende Außenschaft, durch den Wasser bis zum unteren Außenschaftende gelangen kann, wird sicher abgedichtet. Dadurch, dass sich das schmelzbare Band an der Außenschaftinnenseite mindestens bis zum Ende des Innenschaftendes erstreckt, ist ebenfalls gewährleistet, dass keine Feuchtigkeit unterhalb des unteren Innenschaftendes bis ins Schuhinnere dringen kann. Das ist insbesondere dann von Bedeutung, wenn der Innenschaft die Funktionsschicht aufweist. Durch das schmelzbare Band werden Außenschaft, Innenschaft und Brandsohle verklebt und auf weitere Nähte zur Verbindung dieser Komponenten kann verzichtet werden.
Bevorzugt weist der Innenschaft an der dem Außenschaft zugewandten Seite eine wasserdichte, wasserdampfdurchlässige Funktionsschicht auf. Alternativ kann der Außenschaft an der Innenseite, d.h. an der dem Innenschaft zugewandten Seite, eine wasserdichte wasserdampfdurchlässige Funktionsschicht aufweisen.
Die Erfindung betrifft ebenfalls ein wasserdichtes, atmungsaktives Schuhwerk, umfassend einen Außenschaft mit einem unteren Ende, einen Innenschaft mit einem unteren Ende, eine Brandsohle mit einer umlaufenden Außenkante sowie eine Laufsohle, wobei der Innenschaft an der dem Außenschaft zugewandten Seite eine wasserdichte, wasserdampfdurchlässige Funktionsschicht aufweist, dadurch gekennzeichnet, dass sich entlang des unteren Endes des Außenschaftes ein Band aus einem thermoplastischen Material befindet, das am Außenschaft fixiert ist, und das sich von der Außenseite des Außenschaftes über das untere Ende des Außenschaftes bis zur Innenseite des Außenschaftes erstreckt
Bevorzugt ist dieses wasserdichte, atmungsaktive dadurch gekennzeichnet, dass sich das Band bis in die Nahtlöcher der Funktionsschicht erstreckt und den Zwischenraum zwischen Faden und Nahtloch füllt.
Die Erfindung wird anhand der folgenden Figuren näher erläutert. Die Figuren zeigen bevorzugte Ausführungsformen der vorliegenden Erfindung.

This method is also characterized in that the lower outer end of the shaft is enclosed by a fusible band, thus achieving a double sealing of the lower outer shaft end. The often water-conducting outer shaft, through which water can reach the lower outer shaft end, is securely sealed. By virtue of the fact that the fusible band extends on the outer shaft inside at least to the end of the inner shaft end, it is likewise ensured that no moisture can penetrate below the lower inner shaft end into the interior of the shoe. This is particularly important if the inner shaft has the functional layer. Through the fusible band are outer shaft, inner shaft and Glued insole and further seams to connect these components can be omitted.
The inner shaft preferably has a watertight, water vapor permeable functional layer on the side facing the outer shaft. Alternatively, the outer shaft on the inside, ie on the inner shaft facing side, have a waterproof water vapor permeable functional layer.
The invention also relates to a waterproof, breathable footwear comprising an outer shaft with a lower end, an inner shaft with a lower end, an insole with a circumferential outer edge and an outsole, wherein the inner shaft has a waterproof, water vapor permeable functional layer on the side facing the outer shaft characterized in that along the lower end of the outer shaft is a band of a thermoplastic material fixed to the outer shaft and extending from the outer side of the outer shaft to the lower end of the outer shaft to the inner side of the outer shaft
Preferably, this waterproof, breathable is characterized in that the band extends into the seam holes of the functional layer and fills the space between the thread and the seam hole.
The invention will be explained in more detail with reference to the following figures. The figures show preferred embodiments of the present invention.
