Description

Verfahren zur Herstellung von Kunstleder Verfahren zur Herstellung von Kunstleder durch Aufbringen einer Schicht von nur teilweise polymerisiertem Polyvinylchlorid oder anderer unvollständig polymerisierter Kunststoffe auf eine aufgerauhte Gewebeunterlage sind bekannt.Process for the production of artificial leather Process for the production of artificial leather by applying a layer of only partially polymerized Polyvinyl chloride or other incompletely polymerized plastics on a roughened fabric backing are known.

Die Erfindung besteht darin, ,daß die Polyrnerisation der Kunststoffschicht nicht vollständig, sondern etwa nur bis zu 95 °/a durchgeführt wird, und idaß anschließend die nicht polymerisierten Kunststoffteilchen mit kochender verdünnter Natronlauge ausgelaugt werden. Durch diese Bearbeitungsart bilden sich winzige Poren, welche dem Kunstleder die nötige Luftdurchlässigkeit verleihen.The invention consists in that the polymerisation of the plastic layer is not carried out completely, but only up to about 95 ° / a, and then afterwards the unpolymerized plastic particles with boiling dilute caustic soda be leached out. This type of processing creates tiny pores, which give the artificial leather the necessary air permeability.

Bei dem Verfahren wird ein Textilgewebe als Grundlage oder Gerüst verwendet, das an der Seite des aufzubringenden Überzuges angerauht ist, um die Haftfestigkeit des Überzuges an dem Gewebegrund zu erhöhen. Das. Gewebe wird mittels einer Einstreichvorrichtung in laufender Fertigung mit breiigem, urpolymerisiertem, mit Weichmachern versehenem Polyvinylchlorid oder anderen Polymerisationsprodukten einmalig je nach Bedarf dick oder dünn eingestrichen. Der Kunststoffüberzug wird zu ungefähr 95 % polymerisiert, so daß er noch etwas klebrig bleibt. Ein. Abstreifer trennt die Metallfolie von der Kunststoffoberfläche. Anschließend wird das noch nicht ganz fertig polymerisierte Kunstleder etwa 5 Minuten durch kochende, stark verdünnte Natronlauge gezogen. Dabei werden die nicht polymerisierten Kunststoffteilchen ausgelaugt; es entstehen gleichzeitig winzige Poren durch Blasenbildung und Weiterpolymerisation. Die kleinen entstandenen Poren stellen die Verbindung zur Textilfaser her und machenden Kunststoffüberzug luftdurchlässig, schwammartiggeschmeidig und lederähnlich. Nach einem anschließenden T'rocknungsprozeß isst das Kunstleder fertig. Das fertige Produkt zeichnet sich durch hohe Reißfestigkeit und Beständigkeit sowie durch Luftdurchlässigkeit aus. Es ist besonders lederähnlich.In the process, a textile fabric is used as the basis or framework used, which is roughened on the side of the coating to be applied to the To increase the adhesive strength of the coating on the fabric base. That. Tissue is made by means of a coating device in ongoing production with pulpy, urpolymerized, plasticized polyvinyl chloride or other polymerisation products Once applied thickly or thinly as required. The plastic cover will polymerized to about 95%, so that it remains somewhat sticky. A. Scraper separates the metal foil from the plastic surface. Then it will not quite finished polymerized artificial leather about 5 minutes by boiling, strong diluted caustic soda drawn. The unpolymerized plastic particles are thereby removed drained; At the same time, tiny pores are created by the formation of bubbles and further polymerization. The small pores that are created establish and make the connection to the textile fiber Plastic cover permeable to air, spongy, supple and leather-like. To a subsequent The artificial leather is finished with the drying process. The finished product is characterized by high tear strength and durability as well through air permeability. It is particularly leather-like.
