Description
B e s c h r ei b u n g Verfahren zur Herstellung reißfesten Schaumkunstleders Die Erfindung bezieht sich auf ein Verfahren zur Herstellung reißfesten Schaumkunstleders aus Polyvinylchlorid. D e c h r e r i n g Process for the production of tear-resistant foam synthetic leather The invention relates to a method for producing tear-resistant synthetic foam leather made of polyvinyl chloride.
Schaumkunstleder sind nicht reißfest, insbesondere ist ihre Weiterreißfestigkeit ohne besondere Vorkehrungen sehr mangelhaft. Zur Behebung dieses Mangels ist es bekannt, die pastenförmige Masse des Schaumkunstleders auf ein Textilgewebe aufzutragen und nach den verschiedenen Behandlungsphasen sich mit dem Gewebe verbinden zu lassen. Zwar sind die aber es mechanischen Eigenschaften eines solchen Kunstleders ausreichend, muß dafür jedoch ein hoher Herstellungspreis in Kauf genommen werden, da die Verschiedenartigkeit der Stoffe und die damit zusammenhängenden Zulieferungen und Lagerungen das Verfahren verteuern. Ein weiterer Nachteil besteht bei einem solchen Kunstleder darin, daß es sich zum Verkleiden nur von ebenen oder leicht gewölbten Flächen eignet, da das Textilgewebe einer stärkeren Verformung z. B. durch Vakuumziehen nicht standhalten kann und einreißt.Foam synthetic leathers are not tear-resistant, their tear resistance is particularly important very poor without special precautions. To remedy this shortcoming it is known to apply the paste-like mass of the foamed artificial leather to a textile fabric and after the various phases of treatment, to be bonded to the tissue. Although the mechanical properties of such an artificial leather are sufficient, However, a high production price has to be accepted because of the diversity of the substances and the associated supplies and storage the process more expensive. Another disadvantage of such an artificial leather is that it is only suitable for cladding flat or slightly curved surfaces, as the Textile fabric of greater deformation z. B. not withstand vacuum drawing can and tear.
Neuheitsgemäß vermeidet die Erfindung diese Nachteile durch Beimischung von Fasermaterial unter die für die Herstellung der Schaumfolie erforderliche Paste, -Dabei können die Fasern zweckmäßig aus Polyvinylchlorid hergestellt sein.As a novelty, the invention avoids these disadvantages by admixture of fiber material under the paste required for the production of the foam sheet, -The fibers can expediently be made of polyvinyl chloride.
Dieses Verfahren ist für die Herstellung von Kunstleder einfach und billig, da durch das Verfahren ein Arbeitsgang, nämlich der des Vorhaltens des Textilgewebes, und das Gewebe selbst eingespart werden. Der ganze Fertigungsvorgang vom Rohprodukt bis zum fertigen Erzeugnis kann in demselben Betrieb erfolgen, insbesondere dann, wenn die Fasern aus demselben Material wie die Kunstlederpaste hergestellt sind. Außerdem wird durch die Beimischung von Fasern eine hohe Festigkeit erreicht, da die ineinandergewickelten Faserfädchen den Widerstand des Schaumkunstleders gegen Einreißen und gegebenenfalls gegen Weiterreißen außerordentlich erhöhen.This process is simple and easy for the manufacture of artificial leather cheap, because the process makes one operation, namely that of holding the textile fabric, and the fabric itself can be saved. The whole Manufacturing process from the raw product to the finished product can take place in the same company, in particular then when the fibers are made from the same material as the synthetic leather paste are. In addition, by adding fibers, a high level of strength is achieved, because the intertwined fiber threads the resistance of the foam synthetic leather against Tear and, if necessary, increase extraordinarily against further tearing.
Ein weiterer Vorteil ist darin zu sehen, daß das Kunstleder trotz seiner Reißfestigkeit z. B. durch Vakuumziehen beliebig verformbar ist, da das eingebettete Fasergeiüge 1, das die Figur 1 der Zeichnung im Querschnitt wiedergibt, etwa denselben Dehnungskoeffizienten wie die erstarrte Kunstledermasse 2 hat. So kann es als Bezugsstoff vorteilhaft der Herstellung von Polsterüberzügen, Kofferraumauskleidungen und der Abdeckung ähnlicher stark gewölbter Flächen in der Kraftfahrzeugausstattung dienen. Der reißfeste Uberzug für eine Form nach Fig. 2, wie sie z. B. ein Sitznolster, eine Rückenlehne oder eine Radkastenabdeckung im Kofferraum hat, kann aus einer einzigen Schaumfolie fertiggezogen werden, wodurch gegenüber dem bekannten Kunstleder Arbeitsgänge beim Zurechtschneiden und Zusammennähen oder -schweißen der einzelnen Überzugsteile und Material eingespart werden können.Another advantage is to be seen in the fact that the synthetic leather despite its tear strength z. B. is arbitrarily deformable by vacuum drawing, since the embedded Fiber structure 1, which shows the figure 1 of the drawing in cross section, approximately the same Expansion coefficients like the solidified artificial leather mass 2 has. So it can be used as an upholstery fabric advantageous for the production of upholstery covers, trunk linings and the Serve cover similar strongly curved surfaces in the vehicle equipment. The tear-resistant cover for a shape according to FIG. B. a seat cushion, has a backrest or a wheel arch cover in the trunk, can be made from a single foam sheet can be finished, thus compared to the well-known artificial leather Operations involved in cutting and sewing or welding the individual pieces together Cover parts and material can be saved.
Dieselben Vorzüge, nämlich die Vereinfachung des Verfahrens bei einer Kunstlederherstellung und die mit der Reißfestigkeit gepaarte Tiefziehbarkeit der hergestellten Folie, werden auch dann erreicht, wenn die pastenförmige Polyvinylchloridmasse des Schaunkunstleders zweckmäßig auf ein Gewebe aus demselben Material aufgetragen wird.The same benefits, namely the simplification of the procedure for a Synthetic leather production and the deep drawability of the produced film, are achieved even if the paste-like polyvinyl chloride mass of the foam artificial leather is expediently applied to a fabric made of the same material will.
