Definitions

  • the invention relates to a precious metal wire containing, in particular textile fabric.
  • the known catalyst nets are produced from the noble metal wires, for example by machine weaving, knitting or knitting.
  • the bending and tensile strengths and the ductility of the precious metal wires play a limiting role.
  • the bending and tensile strengths and the ductility of the precious metal wires play a limiting role.
  • the bending and tensile strengths and the ductility of the precious metal wires play a limiting role.
  • noble metal wires or metal threads are also used for a variety of other applications. For example, in fuel cells gas diffusion layers of textile fabric are used, which should have a high electrical conductivity and catalytic properties. In this case, wires made of platinum or ruthenium can be used to produce the tissue.
  • precious metal wire is used to form decorative elements in textiles and ribbons.
  • a certain thickness of the decorative element is required in order to achieve visual recognition and visual decorative effect.
  • thick threads or wires can impair the mechanical properties of the fabric, in particular its flexibility. It is also known to admit metal threads as a mark of authenticity or security in banknotes or documents.
  • the invention has for its object to provide a sheet containing or consisting of precious metal wire, and meets the high demands on strength and flexibility.
  • the noble metal wire is formed as a noble metal cord comprising a plurality of strands or a plurality of noble metal strands or a combination of strands and precious metal strands each placed around each other and / or rotated around each other are.
  • a strand here is usually a loose but frictional or positive composite of at least two, preferably at least four and more preferably at least seven precious metal strands understood. These precious metal single wires are either helically wound around each other and / or twisted around each other, as is generally known from wire and rope manufacture.
  • the noble metal cord comprises a plurality, preferably at least four, more preferably at least seven such strands, which are combined into a bundle in which the strands are frictionally or positively connected, or comprises noble metal strands or a combination of strands and Precious metal strands, which are each placed around each other and / or twisted around each other.
  • the noble metal cord comprises a bundle of at least two strands, which are each formed from a plurality of precious metal individual wires placed around one another and / or twisted around one another.
  • Such a noble metal wire in bundle form - here referred to as precious metal cord - shows a high compared to a noble metal single wire with the same radial cross-sectional area high tensile strength and higher flexibility - that is, lower flexural rigidity. These properties also affect the fabrics made from this precious metal cord or those containing the precious metal cord in the same way. This means that the fabric is more flexible and generally also stronger with the same noble metal content compared to a single wire. In addition, with the same precious metal content, the cord is thicker and looks nobler than a single wire.
  • the precious metal cord is made of precious metal or it contains a significant proportion (> 50 wt .-%) of precious metal.
  • precious metal is understood to mean the elements of the platinum group: Os, Ir, Pt, Ru, Rh, Pd and Ag, Au.
  • metal cords of other metals such as of Cu, Fe, Ni, Ti, Co, Cr, Zr, Nb, Mo, Ta, W, Al and alloys based on these metals, in particular non-ferrous metals and stainless steel being a part of such metal cords is therefore for the inventive Fabrics harmless.
  • the sheet according to the invention is flat or it extends in three spatial directions and may be made of fibers or wires or consist of a flat-shaped workpiece, in which one or more precious metal cords are embedded. Because of their low residual stress these cords do not affect the geometric shape of the sheet or little, so that this retains the desired flexibility and flexibility, even with a large cross section of the precious metal cord.
  • the strands - as well as the individual wires - either helically wound around each other and / or twisted around each other, as known from the wire rope or rope production.
  • one or more noble metal strands can also be incorporated into the noble metal cord.
  • the noble metal cord consists of exactly seven laid around each other and / or twisted strands, which are each formed from exactly seven placed around each other and / or twisted around each precious metal individual wires.
  • Stainless steel wires are known by the names "7x7 Cord” or "7x7 Strand”.
  • the noble metal individual wires used to produce the noble metal cord are as thin as possible and advantageously have a diameter in the range of 25 ⁇ to 50 ⁇ , more preferably from 30 ⁇ to 40 ⁇ .
  • a precious metal cord has proven particularly useful if it has a radial cross-section envelope, which has a diameter in the range of 250 ⁇ to 500 ⁇ , preferably in the range of 300 ⁇ to 400 ⁇ .
  • the fabric is composed, for example, of construction, functional and / or decorative threads which form a woven, knitted, knitted, knitted, braided, crocheted, felted or wrought or nonwoven fabric.
  • the construction threads are, for example, the stitch-forming threads of knitted or crocheted fabrics, the warp or weft threads on fabrics, or any joining or finishing seams.
  • Functional threads or ornamental threads have a special optical, chemical or physical effect, which may differ from that of the other threads, such as in their electrical conductivity, the catalytic effect or their aesthetic appearance.
  • Jewelery threads can also be used, for example, to produce visible seams that fulfill a pure design function.
  • the sheet is formed in a preferred embodiment as a fabric in which at least a portion of the construction or functional threads made of glass, ceramic, basalt, carbon, natural fibers or synthetic fibers or combinations thereof.
  • the inorganic fibers such as the fibers of glass, ceramic, basalt or carbon explicitly mentioned above, are often brittle and may be provided with a plastic sheath to facilitate processing to the fabric. Irrespective of this, when using the noble metal cord together with such fibers, it is generally advantageous to finally embed the textile fiber composite in a plastic matrix or to subsequently provide it with a plastic lacquer layer.
  • Particularly suitable for this purpose are sprayable plastics such as epoxy resins, polyetheretherketone (PEEK), polyoxymethylene (POM) or styrene-acrylonitrile (SAN).
  • Carbon fibers are commercially available in different diameters. They consist of individual fibers with diameters of 5 to 8 ⁇ , of which 1000 are combined into strands - so-called "Rowings.” For use with precious metal cords according to the invention Rowing types of 1 K to 12 K are particularly suitable K stands for 1000 individual fibers.
  • This textile composite is characterized by a particularly high strength and flexibility. It can be provided as a dry fiber composite semi-finished product, for example in roll form. For applications in which it depends on a higher flexural rigidity or dimensional accuracy of the fabric, such as in technical molded parts, the textile composite may also be impregnated with a polymerizable, flowable matrix material, such as a resin. After shaping and curing of the matrix material, the desired molded part is obtained.
  • the textile composite can also be coated with a film of a polymerizable matrix material. After forming and curing, the film forms a dense, smooth surface layer on the fiber composite.
  • the diameters of the carbon and / or glass fibers and the noble metal cord are the same. Deviations of the diameters by a maximum of 20% - related to the larger of the two diameters - are acceptable.
  • the natural fibers or synthetic fibers which may also be (spun) threads, preferably consist of linen, hemp, jute, sisal, coconut, cotton, wool, animal hair, silk, viscose, modal, cupro, acetate, Polyester, polyamide, polyimide, aramid, polyacrylonitrile, polytetrafluoroethylene, polyethylene, polypropylene, polyvinyl chloride or polyurethane.
  • the fabric is executed in a preferred embodiment as a garment.
  • the precious metal cord forms only part of the textile and serves, for example, as a functional or decorative element in the form of a thread or a connecting, decorative or finishing seam.
  • the sheet may also be formed as paper, leather, fur, plastic or fiber-reinforced carbon, in which the precious metal cord is incorporated as a functional or decorative element.
  • the sheet is in this case as a flat or three-dimensionally shaped workpiece made of a flexible base material, in which one or more precious metal cords are incorporated.
  • a flat or three-dimensionally shaped workpiece made of a flexible base material, in which one or more precious metal cords are incorporated.
  • the problem of warping or loss of flexibility arises when wires are incorporated which have a significantly different bending stiffness compared to the base material.
  • the flexibility and bending stiffness of the precious metal cord creates a low residual stress within the fabric and can be easily adapted to the given requirements by the bundle shape and size.
  • the precious metal cord functions to ensure the security and authenticity of documents, such as certificates or banknotes or in terms of meeting visual and aesthetic requirements, such as markings or visually appealing deposits in flat construction parts or as a conclusion or decorative stitching on leather or fur products.

insbesondere textiles Flächengebilde  in particular textile fabric
Beschreibung description
Die Erfindung betrifft ein einen Edelmetalldraht enthaltendes, insbesondere textiles Flächengebilde. The invention relates to a precious metal wire containing, in particular textile fabric.
Stand der Technik Der Einsatz von Edelmetalldraht zur Herstellung von Maschenware, insbesondere Netze aus edelmetallhaltigen Drähten, ist für Katalysator-Anwendungen seit langem bekannt. Beispielsweise werden für die Katalyse der Ammoniakverbrennung für die Salpetersäureherstellung Katalysator-Netze aus Platin-Rhodium-Drähten mit Dicken zwischen 60 und 120 μιτι verwendet. Die katalytische Wirkung hängt von der Größe der frei zugänglichen Edelmetall-Oberfläche ab, wobei aber gleichzeitig ein das Katalysator-Netz durchströmender Gasstrom einem möglichst geringen Strömungswiderstand begegnen soll. Die Belegungsdichte des Netzes mit Edelmetalldraht und die Drahtdicke sind hierbei relevante Parameter. PRIOR ART The use of precious metal wire for the production of knitwear, in particular netting made of wires containing noble metal, has been known for a long time for catalyst applications. For example, catalytic networks of platinum-rhodium wires with thicknesses between 60 and 120 μιτι be used for the catalysis of ammonia combustion for the production of nitric acid. The catalytic effect depends on the size of the freely accessible noble metal surface, but at the same time a gas stream flowing through the catalyst network should encounter the lowest possible flow resistance. The density of the network with precious metal wire and the wire thickness are relevant parameters here.
Die bekannten Katalysator-Netze werden aus den Edelmetall-Drähten beispiels- weise durch maschinelles Weben, Stricken oder Wirken gefertigt. Bei diesen Fertigungsmethoden spielen die Biege- und Zugfestigkeiten und die Duktilität der Edelmetalldrähte eine begrenzende Rolle. So sind zum Beispiel zum Verstricken von Drähten aus bestimmten Platin-Rhodium-, Platin-Palladium-Rhodium-, Palladium-Nickel-, Palladium-Kupfer- und Palladium-Nickel-Kupfer-Legierungen nur Edelmetalldrähte mit Durchmessern zwischen 50 bis 120 μιτι und Zugfestigkeiten zwischen 900 und 1050 N/mm2 geeignet. Dicker Edelmetalldraht vermindert die Flexibilität des Netzes. Metalldrähte oder Metallfäden werden auch für eine Vielzahl anderer Anwendungen eingesetzt. So werden beispielsweise in Brennstoffzellen Gasdiffusionsschichten aus textilem Gewebe eingesetzt, das eine hohe elektrische Leitfähigkeit und katalytische Eigenschaften haben soll. Dabei können Drähte aus Platin oder Ruthenium zur Herstellung des Gewebes eingesetzt werden. The known catalyst nets are produced from the noble metal wires, for example by machine weaving, knitting or knitting. In these production methods, the bending and tensile strengths and the ductility of the precious metal wires play a limiting role. Thus, for example, for entangling wires of certain platinum-rhodium, platinum-palladium-rhodium, palladium-nickel, palladium-copper and palladium-nickel-copper alloys only noble metal wires with diameters between 50 to 120 μιτι and tensile strengths between 900 and 1050 N / mm 2 . Thick precious metal wire reduces the flexibility of the network. Metal wires or metal threads are also used for a variety of other applications. For example, in fuel cells gas diffusion layers of textile fabric are used, which should have a high electrical conductivity and catalytic properties. In this case, wires made of platinum or ruthenium can be used to produce the tissue.
Zur Herstellung flexibler Abschirmungen gegen elektromagnetische Felder - wie etwa in Verpackungsmaterial oder in Kleidungsstücken - ist es bekannt, Kupferdrähte in elektrisch leitenden, textilen Flächengebilden als elektrische Leitkontakte einzustricken, einzuweben, einzuwirken oder einzunadeln. Die dabei verwen- deten Metallfäden müssen sehr dünn sein, um die Flexibilität des Textils zu gewährleisten. Sie sind daher nahezu unsichtbar. For the production of flexible shielding against electromagnetic fields - such as in packaging material or in garments - it is known to inject copper wires in electrically conductive, textile fabrics as electrical contacts, weave, act or einzunadeln. The metal threads used must be very thin to ensure the flexibility of the textile. They are therefore almost invisible.
In der Schmuckfertigung wird Edelmetalldraht zur Ausbildung dekorativer Elemente in Textilien und Bändern eingesetzt. Hierfür ist eine gewisse Dicke des Schmuckelements erforderlich, um eine visuelle Erkennbarkeit und optisch dekorative Wirkung zu erreichen. Dicke Fäden oder Drähte können jedoch die mechanischen Eigenschaften des Flächengebildes, insbesondere dessen Biegsamkeit beeinträchtigen. Es ist auch bekannt, Metallfäden als Echtheits- oder Sicherheitskennzeichnung in Banknoten oder Urkunden einzulassen. In jewelery production, precious metal wire is used to form decorative elements in textiles and ribbons. For this purpose, a certain thickness of the decorative element is required in order to achieve visual recognition and visual decorative effect. However, thick threads or wires can impair the mechanical properties of the fabric, in particular its flexibility. It is also known to admit metal threads as a mark of authenticity or security in banknotes or documents.
Bei der Fertigung des jeweiligen Flächengebildes als auch bei seiner spezifischen Anwendung können hohe Kräfte auf den Metalldraht einwirken. Daher liegt grundsätzlich ein besonderes Augenmerk auf der Biege- und Zugfestigkeit des Drahtes, aber auch auf der Flexibilität. Dies sind jedoch widerstreitende Anforderungen; es ist schwierig, gleichzeitig hohen Anforderungen an die Festigkeit und an die Flexibilität zu genügen. Technische Aufgabenstellung In the production of the respective fabric as well as in its specific application, high forces can act on the metal wire. Therefore, there is always a special focus on the bending and tensile strength of the wire, but also on the flexibility. However, these are conflicting requirements; It is difficult to meet high demands on strength and flexibility at the same time. Technical task
Der Erfindung liegt die Aufgabe zugrunde, ein Flächengebilde anzugeben, das Edelmetalldraht enthält oder aus diesem besteht, und das hohen Anforderungen an Festigkeit und Flexibilität genügt. Allgemeine Darstellung der Erfindung The invention has for its object to provide a sheet containing or consisting of precious metal wire, and meets the high demands on strength and flexibility. General presentation of the invention
Diese Aufgabe wird hinsichtlich des eingangs genannten Flächengebildes erfindungsgemäß dadurch gelöst, dass der Edelmetalldraht als Edelmetall-Kordel ausgebildet ist, die mehrere Litzen oder mehrere Edelmetall-Einzeldrähte oder eine Kombination von Litzen und Edelmetall-Einzeldrähten umfasst, die jeweils umeinander gelegt und/oder umeinander verdreht sind. This object is achieved in terms of the aforementioned sheet structure according to the invention that the noble metal wire is formed as a noble metal cord comprising a plurality of strands or a plurality of noble metal strands or a combination of strands and precious metal strands each placed around each other and / or rotated around each other are.
Unter einer Litze wird hier ein in der Regel loser aber reib- oder formschlüssiger Verbund aus mindestens zwei, vorzugsweise mindestens vier und besonders bevorzugt mindestens sieben Edelmetall-Einzeldrähten verstanden. Diese Edelme- tall-Einzeldrähte sind entweder helixartig umeinander gelegt und/oder umeinander verdrillt, wie dies aus der Draht und Seilherstellung allgemein bekannt ist. Under a strand here is usually a loose but frictional or positive composite of at least two, preferably at least four and more preferably at least seven precious metal strands understood. These precious metal single wires are either helically wound around each other and / or twisted around each other, as is generally known from wire and rope manufacture.
Die Edelmetall-Kordel umfasst mehrere, vorzugsweise mindestens vier, besonders bevorzugt mindestens sieben solcher Litzen, die zu einem Bündel zusam- mengefasst sind, in dem die Litzen reib- oder formschlüssig verbunden sind, oder sie umfasst Edelmetall-Einzeldrähte oder eine Kombination von Litzen und Edelmetall-Einzeldrähten, die jeweils umeinander gelegt und/oder umeinander verdreht sind. Besonders bevorzugt umfasst die Edelmetall-Kordel ein Bündel mindestens zweier Litzen, die jeweils aus mehreren, umeinander gelegten und/oder umeinander verdrehten Edelmetall-Einzeldrähten gebildet sind. Ein derartiger Edelmetalldraht in Bündelform - hier als Edelmetall-Kordel bezeichnet - zeigt eine im Vergleich zu einem Edelmetall-Einfachdraht mit gleicher radialer Querschnittsfläche hohe Zugfestigkeit bei gleichzeitig höherer Flexibilität - das heißt, geringerer Biegesteifigkeit. Diese Eigenschaften wirken sich auch auf die aus dieser Edelmetall-Kordel gefertigten oder die Edelmetall-Kordel enthal- tenden Flächengebilde in gleicher Weise aus. Das bedeutet, das Flächengebilde ist bei gleichem Edelmetallgehalt im Vergleich zu einem Einfachdraht flexibler und in der Regel auch fester. Außerdem ist bei gleichem Edelmetallgehalt die Kordel dicker und wirkt edler als ein Einzeldraht. Die Edelmetall-Kordel besteht aus Edelmetall oder sie enthält einen nennenswerten Anteil (>50 Gew.-%) an Edelmetall. Unter„Edelmetall" werden hier die Elemente der Platingruppe: Os, Ir, Pt, Ru, Rh, Pd sowie Ag, Au verstanden. Die flexi- bilitätswahrende oder -erhöhende Wirkung ist auch bei Metallkordeln aus ande- ren Metallen zu erwarten, wie etwa aus Cu, Fe, Ni, Ti, Co, Cr, Zr, Nb, Mo, Ta, W, AI und Legierungen auf Basis dieser Metalle, wobei insbesondere Buntmetalle und Edelstahl zu nennen sind. Ein Anteil an derartigen Metallkordeln ist daher für das erfindungsgemäße Flächengebilde unschädlich. The noble metal cord comprises a plurality, preferably at least four, more preferably at least seven such strands, which are combined into a bundle in which the strands are frictionally or positively connected, or comprises noble metal strands or a combination of strands and Precious metal strands, which are each placed around each other and / or twisted around each other. Particularly preferably, the noble metal cord comprises a bundle of at least two strands, which are each formed from a plurality of precious metal individual wires placed around one another and / or twisted around one another. Such a noble metal wire in bundle form - here referred to as precious metal cord - shows a high compared to a noble metal single wire with the same radial cross-sectional area high tensile strength and higher flexibility - that is, lower flexural rigidity. These properties also affect the fabrics made from this precious metal cord or those containing the precious metal cord in the same way. This means that the fabric is more flexible and generally also stronger with the same noble metal content compared to a single wire. In addition, with the same precious metal content, the cord is thicker and looks nobler than a single wire. The precious metal cord is made of precious metal or it contains a significant proportion (> 50 wt .-%) of precious metal. The term "precious metal" is understood to mean the elements of the platinum group: Os, Ir, Pt, Ru, Rh, Pd and Ag, Au.The flexibility-preserving or increasing effect is also to be expected with metal cords of other metals, such as of Cu, Fe, Ni, Ti, Co, Cr, Zr, Nb, Mo, Ta, W, Al and alloys based on these metals, in particular non-ferrous metals and stainless steel being a part of such metal cords is therefore for the inventive Fabrics harmless.
Das erfindungsgemäße Flächengebilde ist eben oder es erstreckt sich in drei Raumrichtungen und kann aus Fasern oder Drähten gefertigt sein oder aus einem flächig ausgeformten Werkstück bestehen, in das eine oder mehrere Edelmetall- Kordeln eingelassen sind. Wegen ihrer geringen Eigenspannung beeinträchtigen diese Kordeln die geometrische Gestalt des Flächengebildes nicht oder wenig, so dass dieses auch bei großem Querschnitt der Edelmetall-Kordel die gewünschte Biegsamkeit und Flexibilität behält. The sheet according to the invention is flat or it extends in three spatial directions and may be made of fibers or wires or consist of a flat-shaped workpiece, in which one or more precious metal cords are embedded. Because of their low residual stress these cords do not affect the geometric shape of the sheet or little, so that this retains the desired flexibility and flexibility, even with a large cross section of the precious metal cord.
In einer bevorzugten Ausführungsform der Edelmetall-Kordel sind die Litzen - wie auch die Einzeldrähte - entweder helixartig umeinander gelegt und/oder umeinander verdrillt, wie aus der Drahtseil- oder Seilherstellung bekannt. In a preferred embodiment of the noble metal cord, the strands - as well as the individual wires - either helically wound around each other and / or twisted around each other, as known from the wire rope or rope production.
Im Bündel können neben den genannten Litzen auch ein oder mehrere Edelme- tall-Einzeldrähte in die Edelmetall-Kordel eingearbeitet sein. In the bundle, in addition to the strands mentioned, one or more noble metal strands can also be incorporated into the noble metal cord.
Bei einer besonders bevorzugten Ausführungsform ist vorgesehen, dass die Edelmetall-Kordel aus genau sieben umeinander gelegten und/oder umeinander verdrehten Litzen besteht, die jeweils aus genau sieben umeinander gelegten und/oder umeinander verdrehten Edelmetall-Einzeldrähten gebildet sind. So aufgebaute Drähte aus Edelstahl sind unter den Bezeichnungen„7x7 Cord" oder„7x7 Strand" bekannt. In a particularly preferred embodiment, it is provided that the noble metal cord consists of exactly seven laid around each other and / or twisted strands, which are each formed from exactly seven placed around each other and / or twisted around each precious metal individual wires. Stainless steel wires are known by the names "7x7 Cord" or "7x7 Strand".
Im Hinblick auf eine möglichst hohe Flexibilität des Flächengebildes sowie einer bei Katalysatoranwendungen bevorzugt großen Oberfläche des Edelmetalls sind die zur Herstellung der Edelmetall-Kordel eingesetzten Edelmetall-Einzeldrähte möglichst dünn und haben vorteilhafterweise einen Durchmesser im Bereich von 25 μιτι bis 50 μιτι, besonders bevorzugt von 30 μιτι bis 40 μιτι. With regard to the highest possible flexibility of the sheet as well as a surface of the noble metal which is preferably large in the case of catalyst applications, the noble metal individual wires used to produce the noble metal cord are as thin as possible and advantageously have a diameter in the range of 25 μιτι to 50 μιτι, more preferably from 30 μιτι to 40 μιτι.
In dem Zusammenhang hat sich eine Edelmetall-Kordel besonders bewährt, wenn diese eine ihren radialen Querschnitt Umhüllende aufweist, die einen Durchmes- ser im Bereich von 250 μιτι bis 500 μιτι, vorzugsweise im Bereich von 300 μιτι bis 400 μηη hat. In this context, a precious metal cord has proven particularly useful if it has a radial cross-section envelope, which has a diameter in the range of 250 μιτι to 500 μιτι, preferably in the range of 300 μιτι to 400 μηη.
Das Flächengebilde setzt sich beispielsweise aus Konstruktions-, Funktionsund/oder Schmuckfäden zusammen, die ein Gewebe, Gestricke, Gewirke, Gestick, Geflecht, Gehäkel, eine Filz- oder Walkware oder ein Vlies bilden. Bei den Konstruktionsfäden handelt es sich beispielsweise um die maschenbildenden Fäden von Gewirken oder Gestricken, um die Kett- oder Schussfäden bei Geweben oder um etwaige Verbindungs- oder Abschlussnähte. The fabric is composed, for example, of construction, functional and / or decorative threads which form a woven, knitted, knitted, knitted, braided, crocheted, felted or wrought or nonwoven fabric. The construction threads are, for example, the stitch-forming threads of knitted or crocheted fabrics, the warp or weft threads on fabrics, or any joining or finishing seams.
Funktionsfäden oder Schmuckfäden kommt eine besondere optische, chemische oder physikalische Wirkung zu, die von derjenigen der übrigen Fäden abweichen kann, wie etwa in ihrer elektrischen Leitfähigkeit, der katalytischen Wirkung oder ihrer ästhetischen Anmutung. Schmuckfäden können beispielsweise auch zur Herstellung sichtbarer Nähte dienen, die einer reine Designfunktion erfüllen. Functional threads or ornamental threads have a special optical, chemical or physical effect, which may differ from that of the other threads, such as in their electrical conductivity, the catalytic effect or their aesthetic appearance. Jewelery threads can also be used, for example, to produce visible seams that fulfill a pure design function.
Dabei sind alle oder mindestens ein Teil der Konstruktions-, Funktions- oder Schmuckfäden aus der Edelmetall-Kordel gebildet. Eine optische Einlage aus Edelmetall entfaltet ihre ästhetische Wirkung im Flächengebilde erst bei hinreichender Dicke. Mit der Dicke nehmen aber auch Eigenspannung und Biegesteifigkeit zu, die zu unerwünschter Verformung des Flächengebildes führen können. Diesen Nachteil vermeidet der Einsatz der Edelmetall-Kordel gemäß der Erfindung, da diese wegen ihrer hohen Flexibilität auch bei Dicken, die eine hinreichende visuelle Erkennbarkeit und dekorative Wirkung gewährleisten, eine geringe Eigenspannung erzeugt. Des Weiteren wird bei gleichem Edelmetallgewicht eine höhere Wertigkeit durch den größeren Durchmesser erzielt, was im Vergleich mit einem Draht entsprechender Dicke Material kosten einspart. Das Flächengebilde ist bei einer bevorzugten Ausführungsform als Textilerzeugnis ausgebildet ist, in dem mindestens ein Teil der Konstruktions- oder Funktionsfäden aus Glas, aus Keramik, aus Basalt, aus Kohlenstoff, aus Naturfasern oder aus Kunstfasern oder aus Kombinationen davon besteht. Die anorganischen Fasern, wie etwa die oben ausdrücklich genannten Fasern aus Glas, Keramik, Basalt oder Kohlenstoff sind häufig spröde und können mit einer Umhüllung aus Kunststoff versehen sein, um die Verarbeitung zu dem texti- len Flächengebilde zu vereinfachen. Unabhängig davon ist es beim Einsatz der Edelmetall-Kordel zusammen mit derartigen Fasern in der Regel vorteilhaft, den textilen Faserverbund abschließend in eine Kunststoffmatrix einzubetten oder nachträglich mit einer Kunststoff-Lackschicht zu versehen. Geeignet dafür sind insbesondere spritzbare Kunststoffe wie Epoxid-Harze, Polyetheretherketon (PEEK), Polyoxymethylen (POM) oder Styrol-Acrylnitril (SAN). In this case, all or at least part of the construction, functional or jewelry threads are formed from the precious metal cord. An optical insert made of precious metal unfolds its aesthetic effect in the fabric only with sufficient thickness. With the thickness but also increase internal stress and bending stiffness, which can lead to undesirable deformation of the fabric. This disadvantage avoids the use of the noble metal cord according to the invention, since these produce a low residual stress due to their high flexibility even at thicknesses which ensure adequate visual recognition and decorative effect. Furthermore, with the same precious metal weight a higher value is achieved by the larger diameter, which saves costs in comparison with a wire of appropriate thickness material. The sheet is formed in a preferred embodiment as a fabric in which at least a portion of the construction or functional threads made of glass, ceramic, basalt, carbon, natural fibers or synthetic fibers or combinations thereof. The inorganic fibers, such as the fibers of glass, ceramic, basalt or carbon explicitly mentioned above, are often brittle and may be provided with a plastic sheath to facilitate processing to the fabric. Irrespective of this, when using the noble metal cord together with such fibers, it is generally advantageous to finally embed the textile fiber composite in a plastic matrix or to subsequently provide it with a plastic lacquer layer. Particularly suitable for this purpose are sprayable plastics such as epoxy resins, polyetheretherketone (PEEK), polyoxymethylene (POM) or styrene-acrylonitrile (SAN).
Kohlenstofffasern sind im Handel in unterschiedlichen Durchmessern erhältlich. Sie bestehen aus Einzelfasern mit Durchmessern um 5 bis 8 μιτι, von denen jeweils 1000 zu Strängen - sogenannten„Rowings" - zusammengefasst sind. Für den Einsatz mit Edelmetall-Kordeln gemäß der Erfindung sind Rowing-Typen von 1 K bis 12K besonders geeignet, wobei K für 1000 Einzelfasern steht. Carbon fibers are commercially available in different diameters. They consist of individual fibers with diameters of 5 to 8 μιτι, of which 1000 are combined into strands - so-called "Rowings." For use with precious metal cords according to the invention Rowing types of 1 K to 12 K are particularly suitable K stands for 1000 individual fibers.
Bei einer besonders vorteilhaften Ausführungsform des erfindungsgemäßen Flä- chengebildes bilden Fasern aus Kohlenstoff und/oder Glas mit Edelmetall-Kordel einen flächigen Textilverbund. In a particularly advantageous embodiment of the invention Flächenchen image form fibers of carbon and / or glass with precious metal cord a flat textile composite.
Dieser Textilverbund zeichnet sich durch eine besonders hohe Festigkeit und Flexibilität aus. Er kann als trockenes Faserverbundhalbzeug beispielsweise in Rollenform bereitgestellt werden. Für Anwendungen, bei denen es auf eine höhere Biegesteifigkeit oder Formtreue des Flächengebildes ankommt, wie beispielsweise bei technischen Formteilen, kann der Textilverbund auch mit einem polymerisierbaren, fließfähigen Matrixmaterial getränkt sein, wie beispielsweise einem Harz. Nach Formgebung und Aushärten des Matrixmaterials wird das gewünschte Formteil erhalten. This textile composite is characterized by a particularly high strength and flexibility. It can be provided as a dry fiber composite semi-finished product, for example in roll form. For applications in which it depends on a higher flexural rigidity or dimensional accuracy of the fabric, such as in technical molded parts, the textile composite may also be impregnated with a polymerizable, flowable matrix material, such as a resin. After shaping and curing of the matrix material, the desired molded part is obtained.
Alternativ oder ergänzend dazu kann der Textilverbund auch mit einer Folie aus einem polymerisierbaren Matrixmaterial belegt werden. Die Folie bildet nach Formgebung und Aushärten eine dichte, glatte Oberflächenschicht auf dem Faserverbund. Alternatively or additionally, the textile composite can also be coated with a film of a polymerizable matrix material. After forming and curing, the film forms a dense, smooth surface layer on the fiber composite.
Im Hinblick auf eine einfache Verarbeitbarkeit sind die Durchmesser der Fasern aus Kohlenstoff und/oder Glas und der Edelmetall-Kordel im Idealfall gleich. Abweichungen der Durchmesser um maximal 20 % - bezogen auf den jeweils größe- ren der beiden Durchmesser - sind aber akzeptabel. Ideally, for ease of processing, the diameters of the carbon and / or glass fibers and the noble metal cord are the same. Deviations of the diameters by a maximum of 20% - related to the larger of the two diameters - are acceptable.
Besonders bewährt haben sich erfindungsgemäße Textilverbünde aus Edelmetall- Kordel und Kohlenstofffasern. Textile composites of noble metal cord and carbon fibers according to the invention have proven particularly useful.
Bei den Naturfasern oder Kunstfasern, bei denen es sich auch um (gesponnene) Fäden handeln kann, bestehen vorzugsweise aus Leinen, Hanf, Jute, Sisal, Ko- kos, Baumwolle, Wolle, Tierhaar, Seide, Viskose, Modal, Cupro, Acetat, Polyester, Polyamid, Polyimid, Aramid, Polyacrylnitril, Polytetrafluoräthylen, Polyethylen, Polypropylen, Polyvinylchlorid oder aus Polyurethan. The natural fibers or synthetic fibers, which may also be (spun) threads, preferably consist of linen, hemp, jute, sisal, coconut, cotton, wool, animal hair, silk, viscose, modal, cupro, acetate, Polyester, polyamide, polyimide, aramid, polyacrylonitrile, polytetrafluoroethylene, polyethylene, polypropylene, polyvinyl chloride or polyurethane.
Bei einem derartigen Textilerzeugnis, das aus unterschiedlichen Faser- oder Drahtwerkstoffen gefertigt ist, ergibt sich häufig das Problem des Verziehens be- reits bei der Herstellung oder auch erst im Verlauf des bestimmungsgemäßen Einsatzes, wenn sich die Fasern oder Drähte in ihrer Flexibilität und Biegesteifig- keit zu sehr unterscheiden. Bei der Einarbeitung biegesteifer Drähte leidet zudem die Flexibilität des gesamten Flächengebildes. Diese Schwierigkeiten vermeidet die Erfindung, da die Flexibilität und Biegesteifigkeit der Edelmetall-Kordel durch die Bündelform- und -große einfach an die gegebenen Anforderungen angepasst werden kann. Zudem zeigt die Edelmetall-Kordel auch bei vergleichsweise großem Querschnitt eine hohe Flexibilität und erzeugt damit eine geringe Eigenspannung innerhalb des Textilerzeugnisses. Dadurch lässt sie sich auch in Ver- bindung mit Faser- oder Drahtwerkstoffen gänzlich anderer Art reproduzierbar zu verziehungsfreien, flexiblen Textilerzeugnissen verarbeiten. In the case of such a fabric, which is manufactured from different fiber or wire materials, the problem of warping already arises during manufacture or only during the intended use when the fibers or wires are flexible and flexurally stiff too different. The incorporation of rigid wires also suffers the flexibility of the entire fabric. These difficulties avoid the invention, since the flexibility and bending stiffness of the precious metal cord can be easily adapted by the bundle shape and size to the given requirements. In addition, the precious metal cord shows a high flexibility even with a comparatively large cross-section and thus produces a low residual stress within the textile product. As a result, it can also be Bonding with fiber or wire materials of entirely different kind reproducibly to distortion-free, flexible textile products.
Das Textilerzeugnis ist in einer bevorzugten Ausführungsform als Bekleidungsstück ausgeführt. Die Edelmetall-Kordel bildet dabei nur einen Teil des Textils und dient darin beispielsweise als Funktions- oder Schmuckelement in Form eines Fadens oder einer Verbindungs-, Schmuck- oder Abschlussnaht. The fabric is executed in a preferred embodiment as a garment. The precious metal cord forms only part of the textile and serves, for example, as a functional or decorative element in the form of a thread or a connecting, decorative or finishing seam.
Alternativ dazu, kann das Flächengebilde auch als Papier, aus Leder, aus Fell, aus Kunststoff oder aus faserverstärktem Kohlenstoff ausgebildet sein, in wel- ehern die Edelmetall-Kordel als Funktions- oder Schmuckelement eingelagert ist. Alternatively, the sheet may also be formed as paper, leather, fur, plastic or fiber-reinforced carbon, in which the precious metal cord is incorporated as a functional or decorative element.
Das Flächengebilde liegt hierbei als ebenes oder dreidimensional geformtes Werkstück aus einem flexiblen Basismaterial vor, in welches eine oder mehrere Edelmetall-Kordeln eingearbeitet sind. Auch bei dieser Art von Flächengebilde stellt sich das weiter oben bereits erörterte Problem des Verziehens oder der Fle- xibilitätseinbuße, wenn Drähte eingearbeitet werden, die eine im Vergleich zum Basismaterial deutlich unterschiedliche Biegesteifigkeit haben. Die Flexibilität und Biegesteifigkeit der Edelmetall-Kordel erzeugt eine geringe Eigenspannung innerhalb des Flächengebildes und kann durch die Bündelform- und -große einfach an die gegebenen Anforderungen angepasst werden. Hierbei kommen der Edelmetall-Kordel beispielsweise Funktionen in Bezug auf die Gewährleistung der Sicherheit und Echtheit von Dokumenten, wie Urkunden oder Banknoten oder in Bezug auf die Erfüllung optischer und ästhetischer Anforderungen zu, wie etwa als Markierungen oder optisch ansprechende Einlagerungen in flächigen Konstruktionsteilen oder als Abschluss oder Schmucknähte bei Leder- oder Fellwaren. Ausführungsbeispiel The sheet is in this case as a flat or three-dimensionally shaped workpiece made of a flexible base material, in which one or more precious metal cords are incorporated. In the case of this type of fabric, too, the problem of warping or loss of flexibility, which has already been discussed above, arises when wires are incorporated which have a significantly different bending stiffness compared to the base material. The flexibility and bending stiffness of the precious metal cord creates a low residual stress within the fabric and can be easily adapted to the given requirements by the bundle shape and size. Here, the precious metal cord, for example, functions to ensure the security and authenticity of documents, such as certificates or banknotes or in terms of meeting visual and aesthetic requirements, such as markings or visually appealing deposits in flat construction parts or as a conclusion or decorative stitching on leather or fur products. embodiment
