Abstract

The shaped padding body, with a polyolefine foam base material, has an outer textile fabric layer. The foam body surface is embossed, to give projections and recesses. The overlaid textile fabric rests on the projection peaks and is bonded to them, for the recesses to form channels for the escape of steam and vapour. Also claimed is a mfg. process where the textile fabric covering is bonded to the surface projections by an adhesive, a slitted thermoplastic adhesive film or through the use of a thermoplastic nonwoven.

Description

Die Erfindung betrifft einen Polsterformkörper auf Basis ei­ nes Polyolefin-Schaumstoffes, der ein Formteil aus Polyole­ fin-Schaumstoff und eine auf diesem angeordnete Lage eines Textilmaterials umfaßt, ein Verfahren zu seiner Herstellung und die Verwendung eines solchen Polsterformkörpers.The invention relates to a molded cushion body based on egg nes polyolefin foam, which is a molded part made of polyols fin foam and a layer of one arranged thereon Textile material comprises, a process for its preparation and the use of such a molded cushion body.

Polstereinlagen aus Polyolefin-Schaumstoffen sind schon seit längerer Zeit bekannt. Sie zeichnen sich neben guter schwin­ gungs- und stoßdämpfender Wirkung auch dadurch aus, daß sie an den menschlichen Körper anpaßbar sind und gute Langzeitbe­ ständigkeit gegen aggressive Chemikalien, wie Körperschweiß, haben. Andererseits haben sie jedoch den Nachteil, daß sie als Wasserdampfbarrieren und Wärmeisolatoren wirken. Dadurch wird trotz der ausgezeichneten Polsterwirkung des Polyolefin- Schaumstoffes ein unangenehmes Trageklima auf Grund der Durchfeuchtung der Schaumstoffoberfläche bei Anwendungen ver­ ursacht, wie als Rückenpolster für Rucksäcke, Schlagschutz­ polster für Sportausrüstungen (z. B. Schienbein-, Knie-, Ell­ bogen-, Schulterpolster und ähnliche Polster) oder speziell bei Einlagen für Sportschuhe, Freizeitschuhe und orthopädi­ sche Schuhe.Upholstery inserts made of polyolefin foams have been around for a long time known for a long time. They stand out next to good swine gungs- and shock-absorbing effect also characterized in that are adaptable to the human body and good long-term resistance to aggressive chemicals, such as body sweat, to have. On the other hand, they have the disadvantage that they act as water vapor barriers and heat insulators. Thereby is despite the excellent cushioning effect of the polyolefin An uncomfortable wearing climate due to the Moisturization of the foam surface in applications ver causes, like as a back cushion for backpacks, impact protection pads for sports equipment (e.g. shin, knee, ell bow, shoulder pads and similar pads) or special for insoles for sports shoes, casual shoes and orthopedics shoes.

Nach dem heutigen Stand der Technik werden daher Polsterein­ lagen aus Filzen oder aus offen- oder gemischtzelligen Schaumstoffen eingesetzt, welche jedoch den Nachteil haben, daß sie eine zu große Feuchtigkeitsmenge aufnehmen und bei Raumtemperatur zu lange Trocknungszeiten besitzen.According to the current state of the art, upholstery is therefore possible lay from felt or from open or mixed cell Foams are used, but they have the disadvantage that they absorb too much moisture and at Room drying times are too long at room temperature.

Man hat daher auch schon gelochte, perforierte oder genadelte Polsterteile (nach EP-A-0 081 070) aus geschlossenzelligen Schaumstoffen eingesetzt; diese haben jedoch wiederum den Nachteil, daß sie die entstandene Feuchtigkeit unter der Ein­ wirkung des Dampfdruckes zwar durchlassen, jedoch nicht mehr wegführen können, da sie beispielsweise bei Rucksackpolstern oder Schuheinlagen (wo etwa 80 g Wasser bei acht Stunden Tra­ gedauer entstehen) die Feuchtigkeit in ein geschlossenes System führen und die benachbarten Teile so durchnässen, daß die Aufnahmekapazität schnell erschöpft ist.So you already have perforated, perforated or needled Upholstery parts (according to EP-A-0 081 070) made of closed cells Foams used; however, these in turn have the Disadvantage that the moisture under the one Allow the effect of the vapor pressure to pass through, but no longer can lead away, for example with backpack pads or shoe insoles (where about 80 g water with eight hours of tra  time) the moisture in a closed System and wet the neighboring parts so that the absorption capacity is quickly exhausted.

Es ist daher Aufgabe der Erfindung, Polstereinlagen aus ge­ schlossenzelligen Polyolefin-Schaumstoffen zur Verfügung zu stellen, welche gute Wasserdampf-Ableitefähigkeit und gute Durchlüftbarkeit besitzen und daher hohen Tragekomfort bei der Anwendung als Rucksackpolster, Schlagschutzpolster, Schuheinlagen und orthopädische Polsterteile gewährleisten. Die erfindungsgemäßen Polstereinlagen sollen einerseits die ausgezeichneten typischen Grundeigenschaften eines geschlos­ senzelligen Polyolefin-Schaumstoffes, wie hohe Wasserdampf­ dichte, vernachlässigbare Wasseraufnahme, hohe Isolierfähig­ keit, gute Langzeitpolsterwirkung sowie spezifische gute ver­ arbeitungstechnische Eigenschaften, wie ausgezeichnete ther­ mische Verformbarkeit und Verschweißbarkeit beibehalten, aber andererseits die Fähigkeit haben, die ständig vom menschli­ chen Körper produzierte Schweißabsonderung zuverlässig abzu­ führen und der Körperoberfläche ein angenehmes trockenes Klima zu bieten.It is therefore an object of the invention to cushion pads from ge closed-cell polyolefin foams are available represent what good water vapor drainage ability and good Can be ventilated and is therefore very comfortable to wear use as a backpack pad, impact protection pad, Ensure shoe inserts and orthopedic upholstery parts. The cushion inserts according to the invention should on the one hand excellent typical basic properties of a closed cellular polyolefin foam, such as high water vapor dense, negligible water absorption, high insulation capacity speed, good long-term cushioning effect and specific good ver engineering properties, such as excellent ther Mix formability and weldability maintained, however on the other hand, have the ability to be constantly sweat produced by the body reliably lead and the body surface a pleasant dry Climate.

Diese Aufgabe wird erfindungsgemäß mit Hilfe eines Polster­ formkörpers auf Basis eines geschlossenzelligen Polyolefin- Schaumstoffes, der ein Formteil aus Polyolefin-Schaumstoff und eine auf diesem angeordnete Lage eines Textilmaterials umfaßt, gelöst, der dadurch gekennzeichnet ist, daß das Form­ teil eine mit Erhebungen und Vertiefungen versehene geprägte Oberflächenstruktur hat und daß das Textilmaterial auf den Erhebungen der Oberflächenstruktur aufliegt und mit diesen verbunden ist, während die Vertiefungen der Oberflächenstruk­ tur das Abführen von Wasserdampf bewirkende Kanäle bilden.This object is achieved with the aid of a cushion molded body based on a closed-cell polyolefin foam, which comprises a molded part made of polyolefin foam and a layer of textile material arranged thereon, which is characterized in that the molded part is one with elevations and depressions provided embossed surface structure and that the textile material rests on the elevations of the surface structure and is connected to them, while the depressions of the surface structure form the channels leading to the removal of water vapor.

Der Erfindungsgegenstand wird nachstehend unter Bezugnahme auf die beigefügten Figuren ausführlicher beschrieben. The subject of the invention is described below with reference described in more detail on the accompanying figures.  

In diesen zeigt Fig. 1 eine Ausführungsform des Formteils aus Polyolefin-Schaumstoff mit einer geprägten Noppenstruktur. Darin bedeutet 1 die Erhebungen (Noppen), 2 die Vertiefungen der Struktur und 3 das Formteil aus Polyolefin-Schaumstoff. Fig. 3 zeigt das Formteil aus Polyolefin-Schaumstoff 3 mit geprägter Oberflächenstruktur, die Vertiefungen der Struktur 2 mit der aufkaschierten Lage des Textilmaterials 4.In these FIG. 1 shows an embodiment of the molding of polyolefin foam having an embossed knob structure. Therein 1 means the elevations (knobs), 2 the depressions of the structure and 3 the molded part made of polyolefin foam. Fig. 3 shows the molding of polyolefin foam 3 with an embossed surface structure, the depressions of the structure 2 with the laminated layer of the textile material 4.

Fig. 2 zeigt das diskontinuierliche Herstellungsverfahren (Methode A), Fig. 2 shows the batch production method (method A),

Fig. 4 zeigt das kontinuierliche Herstellungsverfahren (Methode B). Fig. 4 shows the continuous manufacturing process (method B).

Der in dem erfindungsgemäßen Polsterformkörper vorliegende Polyolefin-Schaumstoff ist vorzugsweise geschlossenzellig. Dafür eignen sich nach üblichen bekannten Methoden erhaltene geschlossenzellige Polyolefin-Schaumstoffe, die auch einen geringen Anteil an offenen Zellen aufweise können, solange dies die Polsterwirkung bzw. die Wirkung der Wasserdampf-Un­ durchlässigkeit nicht beeinträchtigt.The present in the molded cushion body according to the invention Polyolefin foam is preferably closed-cell. For this purpose, those obtained by customary known methods are suitable closed cell polyolefin foams that also have a can have a low proportion of open cells, as long as this is the cushioning effect or the effect of the water vapor Un permeability not impaired.

Als Grundmaterial für den Schaumstoff werden Polyolefine oder Olefin-Copolymere eingesetzt. Beispiele für geeignete Poly­ olefine sind Homopolymere von Ethylen, wie Polyethylen niede­ rer Dichte, Polyethylen mittlerer Dichte, und Polyethylen ho­ her Dichte, mittels Metallocen-Katalysatoren erhaltene Poly­ olefine, Homopolymere und Copolymere von Propylen, Copolymere von Ethylen mit anderen Olefinen mit 3 bis 8 Kohlenstoff­ atomen, Ethylen-Vinylacetat-Copolymere, Ethylen-Butadien- Copolymere, Ethylen-Vinylchlorid-Copolymere, Ethylen-Acrylat- Copolymere, z. B. Ethylen-Butylacrylat-Copolymere, Ethylen- Methylacrylat-Copolymere, und Propylen-Methacrylat- Copolymere. Die Polyolefine haben vorzugsweise ein mittleres Molekulargewicht von 10.000 bis 100.000.Polyolefins or are used as the base material for the foam Olefin copolymers used. Examples of suitable poly olefins are homopolymers of ethylene, such as low polyethylene rer density, medium density polyethylene, and polyethylene ho density, poly obtained by means of metallocene catalysts olefins, homopolymers and copolymers of propylene, copolymers of ethylene with other olefins of 3 to 8 carbon atoms, ethylene-vinyl acetate copolymers, ethylene-butadiene Copolymers, ethylene-vinyl chloride copolymers, ethylene-acrylate Copolymers, e.g. B. ethylene-butyl acrylate copolymers, ethylene Methyl acrylate copolymers, and propylene methacrylate Copolymers. The polyolefins are preferably medium Molecular weight from 10,000 to 100,000.

Der eingesetzte Polyolefin-Schaumstoff kann mit üblichen Zu­ satzstoffen, wie Farbmitteln, Pigmenten, Porenbildnern, Anti­ oxidationsmitteln, Vernetzungshilfsmitteln und Flammschutz­ mitteln versehen sein. The polyolefin foam used can with usual Zu Substitutes such as colorants, pigments, pore formers, anti oxidizing agents, cross-linking aids and flame retardants be provided with means.  

Das in Form einer Lage auf der geprägten Oberflächenstruktur angeordnete Textilmaterial kann eine beliebige Struktur, wie eine gewebte, gewirkte oder eine Vliesstruktur haben. Vor­ zugsweise besitzt es eine Vliesstruktur. Das Textilmaterial sollte eine möglichst niedrige Wasseraufnahme aufweisen. Vor­ teilhafte Fasern, die diese Forderung erfüllen, sind daher Synthesefasern, wie Polypropylen- oder Polyesterfasern.This in the form of a layer on the embossed surface structure Arranged textile material can have any structure, such as have a woven, knitted or non-woven structure. Before preferably it has a fleece structure. The textile material should have the lowest possible water absorption. Before Partial fibers that meet this requirement are therefore Synthetic fibers such as polypropylene or polyester fibers.

Als Polyolefin-Schaumstoff eignen sich Schaumstoffe, in denen das Polyolefinharz vernetzt oder unvernetzt ist. Eine geziel­ te Vernetzung hat den Vorteil, daß eine gleichmäßige Zell­ struktur bei der Verschäumung erreicht wird. Wie erwähnt eig­ nen sich erfindungsgemäß Polyolefinschaumstoffe, die mit Hilfe üblicher Methoden erhalten worden sind.As a polyolefin foam, foams are suitable in which the polyolefin resin is cross-linked or uncross-linked. A targeted te networking has the advantage that a uniform cell structure is achieved during foaming. As mentioned According to the invention, polyolefin foams which are produced with Have been obtained using conventional methods.

Zur Herstellung der erfindungsgemäßen Polstereinlagen wird der Polyolefin-Schaumstoff entweder in der Form des fertigen Polsters oder, bevorzugt in Form einer Schaumstoffbahn zu­ nächst mit Hilfe einer üblichen Wärmequelle erhitzt und somit erweicht und unter Ausnutzung der thermischen Verformbarkeit des erweichten Schaumstoffes mittels eines Prägewerkzeuges, wie eines Prägestempels oder einer Prägewalze mit einer ge­ prägten Oberflächenstruktur versehen, die ein Muster aus Er­ hebungen und Vertiefungen aufweist. Im Anschluß an die Prä­ gung wird eine Bahn des Textilmaterials aufgelegt und mit den Erhebungen entweder thermisch oder mit Hilfe eines Klebmit­ tels verbunden.To produce the cushion inserts according to the invention the polyolefin foam either in the shape of the finished one Upholstery or, preferably in the form of a foam sheet next heated using a conventional heat source and thus softens and takes advantage of thermal deformability the softened foam using an embossing tool, such as an embossing stamp or an embossing roller with a ge embossed surface structure that a pattern from Er has elevations and depressions. Following the pre a web of textile material is placed on top and with the Elevations either thermally or with the help of an adhesive connected.

Dabei sollte die durch Prägen erzielte Oberflächenstruktur derart sein, daß zwischen den Erhebungen Kanäle gebildet wer­ den, welche die Wirkung haben, Feuchtigkeit mit Unterstützung der Körperwärme nach außen zum Rand des Polsters zu transpor­ tieren, wo die Feuchtigkeit dann verdampfen kann. Eine solche Prägestruktur ist beispielsweise die in Fig. 1 gezeigte Nop­ penprägung. The surface structure achieved by embossing should be such that channels are formed between the elevations, which have the effect of transporting moisture to the edge of the cushion with the aid of body heat, where the moisture can then evaporate. Such an embossing structure is, for example, the nub embossing shown in FIG. 1.

Nach dem Aufkaschieren der Textilbahn auf die Erhebungen (Noppen) des Schaumstoffes entstehen Lüftungskanäle, welche die Feuchtigkeit dank dem thermischen und Feuchtigkeitsgefäl­ le sehr schnell und wirksam vom menschlichen Körper und der Schaumstoffoberfläche nach außen wegführen.After laminating the textile web onto the elevations (Nubs) of the foam, ventilation ducts are created the moisture thanks to the thermal and moisture gradient le very quickly and effectively from the human body and the Guide the foam surface outwards.

Das Verbinden des geprägten Polsterformkörpers mit der Textilbahn kann mit Hilfe eines Klebstoffes, mit Hilfe eines thermoplastischen Klebevlieses oder mit Hilfe eines ge­ schlitzten thermoplastischen Klebefilms erfolgen. Alternativ ist es auch möglich, die Verbindung zwischen der Bahn des Textilmaterials und dem Polyolefin-Schaumstoffkörper unter der Einwirkung von Wärme und Erweichen der Oberfläche zu be­ wirken.The connection of the embossed molded cushion body with the Textile web can be made with the help of an adhesive, with the help of a thermoplastic adhesive fleece or with the help of a ge slotted thermoplastic adhesive film. Alternatively it is also possible to make the connection between the web of the Textile material and the polyolefin foam body under the action of heat and softening the surface Act.

Die endgültige Verformung zu dem gewünschten Formkörper erfolgt vorzugsweise nach dem Prägen und Kaschieren, kann aber auch gleichzeitig mit dem Prägen und dem Kaschieren des Textilmaterials erfolgen. Dabei muß Sorge getragen werden, daß die Wasserdampf leitenden Kanäle, welche von den Vertiefungen der Prägestruktur gebildet worden sind, erhalten bleiben.The final deformation to the desired molded body is preferably done after embossing and laminating but also at the same time as embossing and concealing the Textile material take place. Care must be taken that the water vapor conducting channels, which from the Wells of the embossed structure have been obtained stay.

Das Herstellungsverfahren kann diskontinuierlich oder auch kontinuierlich erfolgen.The manufacturing process can be discontinuous or else done continuously.

Gemäß der in Fig. 2, Methode A dargestellten diskontinuierli­ chen Ausführungsform wird eine Schaumstoffbahn zunächst er­ hitzt, danach in die Prägeform transportiert, in der die Prä­ gung unter Bildung einer geprägten Oberflächenstruktur er­ folgt. Die geprägte Struktur wird erneut erhitzt, wonach die Textilbahn auf die erhitzte Prägestruktur aufgelegt und soweit angepreßt wird, daß die Kaschierung erfolgt. Dabei wird das Textil nur mit den Erhebungen der Prägestruktur verbunden. According to the discontinuous embodiment shown in FIG. 2, method A, a foam web is first heated, then transported to the embossing mold, in which the embossing follows to form an embossed surface structure. The embossed structure is heated again, after which the textile web is placed on the heated embossed structure and pressed so far that the lamination takes place. The textile is only connected to the elevations of the embossed structure.

Die kontinuierliche Herstellungsmethode ist als Methode B in Fig. 4 gezeigt. Fig. 4 zeigt ein kontinuierliches Verfahren, bei welchem anschließend an die erfolgte Prägung die Prägespitzen nochmals kurz erhitzt, oder mit Klebstoff beschichtet werden und das Textil nur mit diesen Prägespitzen verbunden wird. Das kontinuierliche Verfahren kann vollständig "Inline", d. h. in einem automatisierten Verarbeitungsablauf durchgeführt werden; dies bezieht sich ebenso auf die Konfektionierung der Einzelteile aus der Bahnenware, wie das Zuschneiden durch Schneiden oder Stanzen, sofern die Stückzahlen dies erlauben. Dadurch ergeben sich erhebliche zusätzliche Kosteneinsparungen.The continuous manufacturing method is shown as Method B in FIG. 4. FIG. 4 shows a continuous process in which the embossing tips are briefly heated again after the embossing has been carried out, or are coated with adhesive and the textile is connected only to these embossing tips. The continuous process can be carried out completely “inline”, ie in an automated processing sequence; this also applies to the assembly of the individual parts from the sheet goods, such as cutting to size by cutting or punching, if the quantities allow this. This results in considerable additional cost savings.
