Abstract
Description
Es ist bekannt, daß textile Flächengebilde aus synthetischen und/oder nativen Fasern oder Fäden stromlos naßchemisch metallisiert werden können.It is known that textile fabrics made of synthetic and / or native fibers or threads can be electrolessly metallized by wet chemical means.
Es ist außerdem bekannt, daß man auf einer Kunststoffoberfläche abgeschiedene Metallschichten auf galvanischem Wege verstärken kann (R.Weiner, Kunststoff-Galvanisierung, Eugen G. Leutze Verlag, 1973).It is also known that metal layers deposited on a plastic surface can be galvanically reinforced (R.Weiner, Kunststoff-Galvanisierung, Eugen G. Leutze Verlag, 1973).
Eine galvanische Verstärkung von textilen Flächengebilden analog der Kunststoffgalvanisierung ist ebenfalls möglich. Diese führt erwartungsgemäß zu Verklebungen der Fäden an ihren Berührungspunkten, was eine brettartige Versteifung des Materials zur Folge hat.Galvanic reinforcement of textile fabrics analogous to plastic galvanization is also possible. As expected, this leads to the threads sticking together at their contact points, which results in a board-like stiffening of the material.
überraschender Weise wurde nun festgestellt, daß bei einer geringfügigen galvanischen Verstärkung, insbesondere in kontinuierlicher Fahrweise, von mit einer Metallauflage beschichteten textilen Flächengebilden bei niedrigen Amperestärken trotz partieller Verklebung der Fäden die textilen Eigenschaften erhalten bleiben. Die kritische Menge des galvanisch abgeschiedenen Metalls hängt sowohl von den physikalischen Eigenschaften des Metalls wie Härte, Dichte, Duktilität und Kristallinitätsgrad, als auch von denen des textilen Trägermaterials wie E-Modul, Kristallinitätsgrad und Molmasse ab.Surprisingly, it has now been found that with a slight galvanic reinforcement, in particular in a continuous manner, of textile fabrics coated with a metal coating at low Ampere strengths despite partial gluing of the threads, the textile properties are retained. The critical amount of the electrodeposited metal depends on the physical properties of the metal such as hardness, density, ductility and degree of crystallinity, as well as on those of the textile carrier material such as modulus of elasticity, degree of crystallinity and molecular weight.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die vorzugsweise mit Ni, Cu, Sn, Zn, Pb, Au, Ag, Pd, Pt und Cd auf galvanischem Wege verstärkten Fäden, Fasern und textilen Flächengebilde ausgezeichnete thermische und elektrische Leitfähigkeit aufweisen. Weiter ist überraschend, daß die erfindungsgemäß erhaltenen Produkte hervorragende Verträglichkeit in Thermoplasten bzw. Duroplasten aufweisen.The advantages achieved by the invention are, in particular, that the threads, fibers and textile fabrics, which are preferably galvanically reinforced with Ni, Cu, Sn, Zn, Pb, Au, Ag, Pd, Pt and Cd, have excellent thermal and electrical conductivity. It is also surprising that the products obtained according to the invention have excellent compatibility in thermoplastics or thermosets.
Die kontinuierliche galvanische Verstärkung wird vorzugsweise unter Warenbewegung durchgeführt, beispielsweise indem das metallisierte, galvanisch zu verstärkende Textilgut im Galvanobad so über Rollen geführt wird, daß seine Transportrichtung mindestens zweimal, vorzugsweise mehrfach wechselt. Ein Verkleben an den Garn- bzw. Maschenkreuzungspunkten durch zu große Metallabscheidung wird so verhindert.The continuous galvanic reinforcement is preferably carried out with movement of the goods, for example by guiding the metallized textile material to be galvanically reinforced in the electroplating bath so that its direction of transport changes at least twice, preferably several times. This prevents sticking at the yarn or stitch crossing points due to excessive metal separation.
Die zu verstärkende Metallschicht kann stromlos naßchemisch etwa gemäß DE-OS 2 743 768, oder auf eine beliebige andere Weise aufgebracht werden, z.B. durch Aufdampfen oder "Spattern" nach dem Kathodenstrahlverfahren.The metal layer to be reinforced can be applied electrolessly, wet-chemically, for example in accordance with DE-OS 2 743 768, or in any other way, for example by vapor deposition or " S pattern " using the cathode-ray method.
Gegenstand der vorliegenden Erfindung ist daher ein Verfahren zur Herstellung metallisierter textiler Flächengebilde, wie Gewebe, Gewirke, Vliese, Filze usw. aus nativen oder synthetischen Fäden oder Fasern, dadurch gekennzeichnet, daß man das textile Flächengebilde mit einer elektrisch leitenden Metallschicht überzieht und diese Metallschicht auf galvanischem Wege verstärkt.The present invention therefore relates to a process for the production of metallized textile fabrics, such as woven fabrics, knitted fabrics, fleeces, felts, etc., from native or synthetic threads or fibers, characterized in that the textile fabric is coated with an electrically conductive metal layer and this metal layer galvanically reinforced.
Die zu verstärkende Metallschicht ist in weiten Grenzen variierbar. Sie sollte jedoch einerseits einen gleichmäßigen Stromfluß gewährleisten, andererseits aus wirtschaftlichen Gründen möglichst dünn sein. Daher werden Metallauflagen von 1 bis 20 g Metall/m textiles Flächengebilde bevorzugt.The metal layer to be reinforced can be varied within wide limits. However, on the one hand, it should ensure a uniform current flow, on the other hand, it should be as thin as possible for economic reasons. Metal layers of 1 to 20 g metal / m textile fabric are therefore preferred.
Die Stärke der galvanisch abgeschiedenen Metallschicht liegt bei Kupfer, Nickel und Cobalt zwischen 10 und 40 g/m2, bei Gold, Blei, Zinn, Cadmium zwischen 10 und 250 g/m2.The thickness of the electrodeposited metal layer is between 10 and 40 g / m 2 for copper, nickel and cobalt, and between 10 and 250 g / m 2 for gold, lead, tin, cadmium.
Die galvanische Verstärkung kann mit sauren und alkalischen Galvanisierungsbädern durchgeführt werden.The galvanic reinforcement can be carried out with acidic and alkaline galvanizing baths.
Das erfindungsgemäße Verfahren hat den Vorteil, daß teure Reduktionsmittel, wie Diethylaminoboran, Natriumborhydrid, Natriumhypophosphit, die bei der chemischen Abscheidung des Metalls an der Substratoberfläche verbraucht werden, durch den preiswerten elektrischen Strom ersetzt werden.The process according to the invention has the advantage that expensive reducing agents, such as diethylaminoborane, sodium borohydride, sodium hypophosphite, which are consumed in the chemical deposition of the metal on the substrate surface, are replaced by the inexpensive electric current.
Ein weiterer Vorteil des vorliegenden Verfahrens der galvanischen Verstärkung liegt in der wesentlich leichteren Handhabbarkeit der galvanischen Bäder. Bei einem naßchemischen stromlosen Metallisierungsbad müssen pH-Wert und Zusammensetzung immer wieder analysiert und mit den fehlenden Bestandteilen ergänzt werden.Another advantage of the present galvanic amplification method is that it is much lighter Manageability of the galvanic baths. In the case of a wet-chemical electroless metallization bath, the pH value and composition have to be analyzed again and again and the missing components added.
Mit dem Verfahren der galvanischen Verstärkung kann eine reduktiv abgeschiedene Metallauflage, die oxidationsempfindlich ist, durch eine unempfindliche Metallschicht gegenüber Oxidantien, wie Sauerstoff der Luft geschützt werden.With the process of galvanic amplification, a reductively deposited metal coating that is sensitive to oxidation can be protected against oxidants such as oxygen in the air by an insensitive metal layer.
Die elektrolytisch abgeschiedene Metallschicht zeigt aufgrund der hohen elektrischen und thermischen Leitfähigkeit gute Wärmestandfestigkeit, starkes Reflexionsvermögen für auftreffende elektromagnetische Strahlung. Dadurch sind solche metallisierten textilen Flächengebilde z.B. zur Herstellung von flexiblen Schirmantennen für Radarwellen geeignet.Due to the high electrical and thermal conductivity, the electrolytically deposited metal layer shows good heat resistance, strong reflectivity for incident electromagnetic radiation. As a result, such metallized textile fabrics are e.g. suitable for the production of flexible shield antennas for radar waves.
