Abstract

Tufted, woven or knitted surface covering, consisting of a textile carrier formed from a nonwoven or from a fabric and of pile yarns which are knitted with metal filaments and needled into the carrier and which are tied in the carrier by means of a back coating, in which the textile carrier (1) has an imprint of soot and/or graphite and/or metal bound by means of a binder and of a grading curve of 10 microns to 2 mm, incorporated in or added to the carrier by surface carbonisation. In addition, the pile yarns (2) can be tied in the carrier (1) by means of a coating of a binder, for example resin, containing soot and/or graphite and/or metal. To produce a light- coloured surface covering, a light or colourable covering layer (5), for example a covering nonwoven, is needled onto the impregnated carrier. Metal filaments and/or carbon fibres can also pass through the impregnated carrier (1). In the production process, the textile carrier is first made and thereafter is impregnated by immersion in or spraying with a liquid containing the soot or the graphite or metal, whereupon the needling of the pile fibres and their tying in the carrier take place in a way known per se.

Description

Gegenstand der Erfindung ist eine getuftete, gewebte oder gewirkte Flächenverkleidung aus einem von einem Vlies oder Gewebe gebildeten textilen Träger und mit Metallfäden und/oder Kohlenstoff-Fasern durchwirkten Florfäden, die in den Träger eingenadelt und mittels einer Rückenbeschichtung in den Träger eingebunden sind.The invention relates to a tufted, woven or knitted surface cladding made of a textile backing formed by a nonwoven or woven fabric and pile threads knitted with metal threads and / or carbon fibers, which are needled into the backing and integrated into the backing by means of a back coating.

Die elektrostatische Aufladung der im wesentlichen aus Kunststoffmaterial bestehenden getufteten Flächenverkleidungen ist nach wie vor ein nur unbefriedigend gelöstes Problem. Zu ihrer Beseitigung oder wenigstens Verringerung ist es bekannt, in die Flächenverkleidung jedenfalls partiell mit Metallfäden durchwirkte Florfäden einzunadeln und den Träger vor der Aufbringung der die Einbindung der Florfäden in den Träger bewirkenden Rückenbeschichtung mit einem Metallgewbe zu hinterlegen, mit dessen Hilfe nach der Verlegung der Flächenverkleidung - beispielsweise mittels Schrauben - eine Erdung herbeigeführt wird. Mit Hilfe dieser bekannten Flächenverkleidungen kann die elektrostatische Aufladung nur ungenügend vermindert werden. Dies hat seine Ursache einerseits darin, daß das elektrische Potential nur im unmittelbaren Umfeld der vereinzelt eingewirkten Metallfäden abgeleitet wird, in den übrigen Zonen jedoch erhalten bleibt. Die wesentliche Ursache für die ungenügende Ableitung des Potentials ist jedoch darin zu sehen, daß zur Gewährleistung einer ausreichenden Einbin dung der Florfäden in den Träger nur relativ weitmaschige Metallgewebe als Hinterlegung verwendet werden können, so daß ein leitender Kontakt der Metallfäden mit dem Gewebe nur zufälling und dementsprechend selten erfolgtist, der weitaus größere Teil der eingewirkten Metallfäden dagegen wirkungslos bleibt.The electrostatic charging of the tufted surface cladding, which essentially consists of plastic material, is still an unsatisfactorily solved problem. In order to eliminate or at least reduce it, it is known to at least partially thread piles through which the ply threads are interwoven with metal threads and to deposit the backing with a metal fabric before applying the backing coating that binds the piles in the carrier, with the aid of which after laying the ply covering - for example by means of screws - earthing is brought about. With the help of these known surface claddings, the electrostatic charge can be reduced insufficiently. This is due on the one hand to the fact that the electrical potential is only dissipated in the immediate vicinity of the isolated metal threads, but is retained in the other zones. The main reason for the insufficient derivation of the potential can be seen in the fact that to ensure sufficient involvement The pile threads in the carrier can only be used as a relatively wide-meshed metal mesh, so that conductive contact of the metal threads with the mesh is accidental and, accordingly, seldom, but the far larger part of the metal threads acted on remains ineffective.

Der vorliegenden Erfindung liegt als Aufgabe die Schaffung einer getufteten Flächenverkleidung mit einem durchgehend über die gesamte Fläche gleichmäßig geringen Oberflächen- und Durchgangswiderstand zugrunde, bei dem die Gefahr des Entstehens einer elektrostatischen Aufladung somit praktisch vollständig vermieden ist. Die Erfindung besteht darin, daß der textile Träger mit einer Impretur aus einem mittels eines Bindemittels gebundenen leitfähigen Material versehen ist.It is an object of the present invention to provide a tufted surface covering with a surface and volume resistance that is uniformly low throughout the entire surface and in which the risk of electrostatic charging is thus practically completely avoided. The invention consists in that the textile carrier is provided with an imprint made of a conductive material bound by means of a binder.

Durch die Erfindung ist eine textile getuftete Flächenverkleidung geschaffen, bei der der Träger in seiner Gesamtheit einen geringen Oberflächenwiderstand und damit eine hohe Leitfähigkeit besitzt, wobei die Florfäden bei jeder Durchnadelung selbst in ummittelbar leitendem Kontakt mit dem Träger stehen. Eine sich bildende elektrostatische Aufladung wird somit unmittelbar in das Trägergewebe abgeleitet und kann über das Trägergewebe bzw. Trägervlies geerdet werden.The invention provides a textile tufted surface covering in which the carrier as a whole has a low surface resistance and thus a high conductivity, the pile threads being in direct conductive contact with the carrier with each needling. An electrostatic charge that forms is thus dissipated directly into the carrier fabric and can be grounded via the carrier fabric or carrier fleece.

Vorteilhaft besteht die Impretur aus Ruß und/oder Graphit und/oder Metall einer Sieblinie von 10 um bis 2 mm, die durch Oberflächenkarbonisierung in bezw. an den Träger ein- bezw. angelagert sind, wobei zur weiteren Verbesserung einerseits Florfäden zusätzlich zur Impretur des textilen Trägergewebes bezw. Trägervlieses in dem Träger mittels einer Beschichtung aus einem mit Ruß und/oder Graphit und/oder Metall gefüllten Bindemittel, beispielsweise Harz. eingebunden und/oder in den Träger Metallfäden eingearbeitet sein können. Zur Herstellung einer hellfarbigen Flächenverkleidung ist vorteilhaft auf den imprägnierten Träger eine helle bezw. einfärbbare Deckschicht, beispielsweise ein Deckvlies, aufgenadelt.Advantageously, the imprint consists of soot and / or graphite and / or metal with a sieve line of 10 .mu.m to 2 mm. to the wearer. are attached, whereby for further improvement pile threads on the one hand in addition to the interpretation of the textile Carrier fabric or Carrier fleece in the carrier by means of a coating of a binder filled with carbon black and / or graphite and / or metal, for example resin. integrated and / or metal threads can be incorporated into the carrier. To produce a light-colored surface cladding, a light bezw is advantageously on the impregnated carrier. dyeable cover layer, for example a cover fleece, needled.

Die Herstellung der erfindungsgemäßen getufteten Flächenverkleidung erfolgt vorteilhaft in der Weise, daß zunächst der textile Träger hergestellt und gegebenenfalls mechanisch, chemisch oder thermisch verfestigt und danach die Impretur durch Tauchen in einen oder Besprühen mit einer den Ruß bezw. das Graphit oder Metall enthaltenden Flüssigkeit in bezw. an den textilen Träger ein- oder angelagert wird, worauf in an sich bekannter Weise das Einnadeln der Florfasern und deren Einbindung in den Träger erfolgt. Als Tauchbad bzw. Sprühflüssigkeit kommt hierbei vorteilhaft eine Harzsispersion mit hohen Binde- und molekularkinetischen Kräften zum Einsatz.The tufted surface cladding according to the invention is advantageously produced in such a way that the textile backing is first produced and, if appropriate, mechanically, chemically or thermally solidified, and then the imprint is immersed in or sprayed with the soot. the liquid containing graphite or metal in or. is incorporated or attached to the textile backing, whereupon the pile fibers are needled and integrated into the backing in a manner known per se. A resin dispersion with high binding and molecular kinetic forces is advantageously used as the immersion bath or spray liquid.

Die Erfindung ist nachstehend anhand der beigefügten Zeichnung beispielsweise erläutert.The invention is explained below with reference to the accompanying drawing, for example.

Die in der Zeichnung wiedergegebene getuftete Flächenverkleidung besteht aus einem im Beispielsfalle von einem Vlies gebildeten textilen Träger 1 und mit Metallfäden durchwirkten Florfäden 2, die in den Träger 1 eingenadelt und mittels einer Rückenbeschichtung in den Träger eingebunden sind. Der textile Träger 1 ist mit einer Impretur aus einem leitfähigen Material versehen, das vorzugsweise von Ruß und/oder Graphit und/oder Metallpulver einer Sieblinie von 10 um bis 2 mm gebildet ist und durch Oberflächenkarbonisierung oder mittels eines Bindemittels, beispielsweise einem Harz, in bezw. an den Träger ein- bezw. angelagert ist. Im Beispielsfalle sind zur weiteren Erhöhung der Leitfähigkeit die Florfäden 2 in dem Träger 1 mittels einer Beschichtung 4 eingebunden, die in einer der Impretur entsprechenden Weise aus einem mit Ruß und/oder Graphit und/oder Metall gefüllten Bindemittel besteht und auf den bereits die Florfäden enthaltenden Träger 1 aufgebracht wird. Auf die Schicht 4 ist eine weitere, der üblichen Rückenbeschichtung entsprechende Schicht 3 aus Latex oder Polyurethanschaum aufgebracht.The tufted surface covering shown in the drawing consists of a textile backing 1 formed by a nonwoven in the example and web threads 2 knitted with metal threads, which are needled into the backing 1 and integrated into the backing by means of a back coating. The textile backing 1 is made of a conductive material Provide material, which is preferably formed of soot and / or graphite and / or metal powder with a sieve line of 10 .mu.m to 2 mm and by surface carbonation or by means of a binder, for example a resin, in or. to the wearer. is attached. In the example, to further increase the conductivity, the pile threads 2 are integrated in the carrier 1 by means of a coating 4 which, in a manner corresponding to the interpretation, consists of a binder filled with carbon black and / or graphite and / or metal and on which the pile threads already contain Carrier 1 is applied. A further layer 3 of latex or polyurethane foam corresponding to the usual back coating is applied to layer 4.

Im dargestellten Beispiel ist auf den imprägnierten Träger eine helle Deckschicht 5, beispielsweise ein Deckvlies aufgenadelt, die jedoch im Falle der Herstellung einer dunkelfarbigen Flächenverkleidung entbehrlich ist. Die Erdung erfolgt durch Verschrauben der Flächenverkleidung mittels einer gegebenenfalls mit einer Metallscheibe unterlegten Schraube 6 gegen eine gebäudefeste Leiterplatte 8 an einer beliebigen nicht störenden Stelle, wobei die Entfernung einer nicht leitfähigen (isolierenden) Rükkenbeschichtung nicht erforderlich ist. Es genügt zu einer ausreichenden Ableitung und damit zur Verhinderung des Aufbaus einer Spannung alleine der Kontakt der Schraube und gegebenenfalls Unterlegscheibe zu den Metallfäden im Flor zu dem leitfähigen Träger 8. In the example shown, a light-colored cover layer 5, for example a cover fleece, is needled onto the impregnated support, but this is unnecessary in the case of producing a dark-colored surface covering. The grounding is carried out by screwing the surface cladding against a building-fixed circuit board 8 at any non-disturbing point by means of a screw 6, optionally underlaid with a metal washer, the removal of a non-conductive (insulating) back coating not being necessary. It suffices for sufficient dissipation and thus to prevent the build-up of a voltage simply by the contact of the screw and, if appropriate, the washer with the metal threads in the pile with the conductive carrier 8.
