Description
Kunstleder und Verfahren zu seiner Herstellung Die Erfindung bezieht sich, auf ein neuartiges Kn inätlieder von hoher Dehnbarkeit und Verformbarke,it, das mnt einem textilfaserih@altigen Träger, vorzu gs.weis,e einem Textiiligewebe oder Textüligewirke, versieben ist.Artificial leather and process for its manufacture The invention relates on a new type of knuckle of high elasticity and deformability, it, This must be done on a textile fiber carrier, preferably a textile fabric or knitted fabrics, is sieved.
Kunstleder mit textilfaserhaltigem Träger sind an s,nch bekannt. Sie weisen jedoch eine sehr geringe Dehnbarkeit und Verformibark eit auf, da bei diesen bekannten Kunstledern eine innige Verbindung zwischen der gesamt-en, Trägeroberfläche und der Kumsflie:d,erdeckschicht besteht, wobei diie Hohlräume zwisichen den- einzelnen. Fäden des Gewirkes oder Gewebes mit einer sie mehr oder minder ausfüllenden und ihre Seitenwände miteinander verbindenden Kunststoffmasse versehen sind.Synthetic leather with a textile fiber-containing carrier are known from s, nch. she However, they have a very low ductility and deformability, as they do known artificial leathers create an intimate connection between the entire support surface and the Kumsflie: d, covering layer consists, with the voids between the individual. Threads of the knitted fabric or fabric with a more or less filling and their side walls are provided interconnecting plastic compound.
Die Dehnbarkeit und Verformbarkei:t des Kunstleders, gemäß der Erfindung wird dadurch erzielt, daß die Kunsitlederdeckscbiicht mit dem textilfaserhaltigen Träger nur an einzelnen, jedoch, vorzugsweise gleichmäßig über die ganze Fläche verteilten Stellen verbunden ist.The extensibility and deformability of the artificial leather, according to the invention is achieved in that the synthetic leather cover sheet with the textile fiber-containing Carriers only on individual ones, however, preferably evenly over the entire surface distributed places is connected.
Diesie neuartige, gleichsam punktweise Verbindung zwischen Träger und Kunstllederdeckschicht, welche in keiner Weise die Dehnbarkeit des fertigen Kunstleders beeinträchtigt, kann beispielsweise dadurch erzielt werden, daß von dem textil.faserhaLtigen Träger nur dit in seiner Oberfläche liegenden, mehr oder milndier konvex verlaufenden Fadenbeilie mit der Unterseite der Kunistlederdeckächicht verbunden sind.This is the new kind of point-wise connection between girders and synthetic leather top layer, which in no way affects the extensibility of the finished Impaired artificial leather can be achieved, for example, that of the textile-fiber-containing carrier only lies in its surface, more or less with the underside of the synthetic leather top layer are connected.
Für die Herstellung derartiger hochelastischer und hochverformbarer Kunstleder schlägt die Erfindung verschiedene Verfahrenswege vor.For the production of such highly elastic and highly deformable The invention proposes various methods for artificial leather.
So kann beispielsweise der Textilträger in ungedieihntem Zusitunde auf eine noch gelatinösie thermopliastischie Kunsitstoff-olie derart aufgedrückt werden, daß die aus der Oberfläche der Textiilträgerschicht (Gewebe oder Gewirke) konvex hervorstehenden Fadenteile in die eine annähernd pastöse Plastizität aufweisende Unterseide der noch gelatinösien Kunststoffod,ie hineingedrückt werden.For example, the textile backing can be used in an unsuitable condition so pressed onto a still gelatinous thermoplastic plastic-oil that from the surface of the textile carrier layer (woven or knitted fabric) convex protruding thread parts in which an approximately pasty plasticity exhibiting Underside of the still gelatinous plastic body that is pressed into it.
Man ist jedoch, keineswegs darauf angewiesen, daß die Verbindung zwisichen Kunstlederdeckschicht und Textilträger nur an den in der äußersten Oberfläche des textilfaserhaltigen Trägers konvex verlaufenden Fadenteilen erfolgt; man kann vielmehr - insbesonder:e dann, wenn der Textilträger keine einer punktweis,e#n Verbindung zwischen dien beiden Schichten günsitige natürliche Struktur aufweist-die Größe und Dichte der Verbindungsstellen zwisichen Kunstlederd,ecks.chncht und Träger auch willkürlich, wählen, indem man beispielsweise auf die Oberfläiche des Trägers zunächst eine dünne Kunststoffolie auflegt, die in ihrer Gesamtheit oder deren der Trägerschicht zugewandte Seite -gegebenienfalls unter Anwendung chemischer und/oder physikailisicher Mittel - so besichaffen ist oder in, einen solchen Zustand versetzt wird, d!aß beim Hindurchführen der mit der Kunststoffoliie belegten Trägerschicht zwischen Walzen, von denen mindestens eine warzernarüige Oberflächenstruktur mit dien einzelnen Verbindungsstellen entsprechenden Vorsprüngen od. dgl. aufweist, an diesen Stellen der Träger unter mehr oder minder starkem Druck mit der Kunststoffolie verbunden wird.However, one is in no way dependent on the connection between them Synthetic leather top layer and textile backing only on those in the outermost surface of the textile fiber-containing carrier is carried out convexly extending thread parts; one can rather - in particular: e when the textile carrier does not have a point-wise, e # n connection between the two layers has a favorable natural structure - the size and density of the connection points between imitation leather, ecks.chncht and carrier as well arbitrarily, choose, for example, by first touching the surface of the support a thin plastic film is placed on the carrier layer in its entirety or on it facing side - if necessary, using chemical and / or physical safety Means - as is or is placed in such a state, that is, when Passing the carrier layer covered with the plastic film between rollers, of which at least one warmer-like surface structure with the individual connection points Corresponding projections or the like. Has, at these points of the carrier below more or less strong pressure is connected to the plastic film.
Alls. physikalische Mittel kommen in erster Linie Wärmeeinwirkungen in Frage, durch die die dem Träger zugewandte Seite der Kunststoffolie plastifiziert oder mindestens oberflI.chlich zum Schmelzen gebracht wird. Dieses Plastifiziieren oder Schmelzen kann dadurch auf die gewünschten einzelnen Verbindungsstellen beschränkt werden, daß die eine Warzenoherfläche au fweilsende Walze oder Walzen beheizt wird bzw. werdien.Everything. physical means come primarily from exposure to heat in question, through which the side of the plastic film facing the carrier is plasticized or at least superficially melted. This plasticizing or melting can thereby be limited to the desired individual connection points be that the one ware upper surface aufweilsende roller or rollers is heated or will.
Zur Beseitigung etwaiger zurückbleibender störender Eindrücke der Warzenwalze kann die auf diese Weise mit dier Trägerschicht verbundene, mehr oder minder dünine Kunistatoffolie in an- sich bekannter Weise ein oder mehreremal mit Kunststoff beschichtet und anschließend in jeder gewünschten Weise geprägt und profiliert werden.To remove any remaining disturbing impressions of the Nipple roller can be connected to the carrier layer in this way, more or less thin plastic film one or more times in a known manner Plastic coated and then embossed and profiled in any desired way will.
Das, als Träg ers,chicht dienende Textilgewebe kan#i beispielsweise aus stark gekräuselten Kunststoffäden bestehen., die eine hohe Elastizität aufweisen.The textile fabric serving as a carrier layer can, for example consist of strongly crimped plastic threads, which have a high elasticity.
