  Verfahren zur Nachbehandlung von Kunstlederplatten aus einem Gemenge von Hadern-und Cellulose sowie Latex als Bindemittel, das auf der Faser mit einem sauren Salz ausgefällt wird. 



   Der vorliegenden Erfindung wird die Aufgabe zugrunde gelegt, Kunstlederplatten, welche unter Verwendung von Latex als Bindemittel hergestellt werden, lagerfähig zu machen. Es hat sich ergeben, dass die bisher bekannten derartigen Kunstlederarten nicht haltbar sind, sondern nach längerer Lagerzeit brüchig werden. Es sind infolgedessen diese bekannten Platten zur Herstellung von Koffern u. dgl. nicht geeignet, weil hiefür das Material eine besondere Dauerhaftigkeit und Festigkeit aufweisen muss. 



   Es hat sich die   überraschende   Tatsache ergeben, dass Kunstleder, welches unter Verwendung von Latex hergestellt wird, eine unbegrenzte Lagerfähigkeit erhält, wenn die Kunstlederplatten mit animalischen, vegetabilischen oder mineralischen Fettstoffen vorerst   durchtränkt   werden und nachher ein Glätten der   Oberfläche   in einer hydraulischen Presse oder in einem Kalander erfolgt. 



   Durch diese Massnahme wird das Latex von der Einwirkung des Luftsauerstoffes vollkommen abgeschlossen. 



   Es wird der schädliche Einfluss des Sauerstoffes auf das Latex verhindert und eine besondere Haltbarkeit des Materials bewirkt. 



   Nach einem erprobten Ausführungsbeispiel wird das Kunstleder gemäss der Erfindung in der Weise hergestellt, dass Hadern unter Zusatz von Cellulose auf einem Holländer verarbeitet, hierauf mit Latex und schwefelsaurer Tonerde bzw. Alaun vermengt werden, um ein Ausfällen des Latex auf dem Fasermaterial zu bewirken. Die aus dem Faserbrei geformten Platten werden sodann mit animalischen, vegetabilischen

  Process for the aftertreatment of synthetic leather panels made from a mixture of rag and cellulose as well as latex as a binder, which is precipitated on the fiber with an acid salt.



   The present invention is based on the object of making synthetic leather panels which are produced using latex as a binder, storable. It has been found that the previously known types of artificial leather of this type are not durable, but rather become brittle after a long period of storage. As a result, these known plates for the production of suitcases and. The like. Not suitable, because for this the material must have a particular durability and strength.



   The surprising fact has emerged that artificial leather which is made using latex has an unlimited shelf life if the artificial leather panels are first impregnated with animal, vegetable or mineral fatty substances and then the surface is smoothed in a hydraulic press or in a Calender takes place.



   This measure completely isolates the latex from the effects of atmospheric oxygen.



   The harmful influence of oxygen on the latex is prevented and the material is particularly durable.



   According to a tried and tested embodiment, the artificial leather according to the invention is produced in such a way that rags are processed on a Dutchman with the addition of cellulose, then mixed with latex and sulfuric alumina or alum in order to cause the latex to precipitate on the fiber material. The plates formed from the pulp are then mixed with animal and vegetable

PATENT-ANSPRUCH : Verfahren zur Nachbehandlung von Kunstlederplatten aus einem Gemenge von Hadern und Cellulose sowie Latex als Bindemittel, das auf der Faser mit einem sauren Salz ausgefällt wird, dadurch gekennzeichnet, dass diese Platten mit animalischen, vegetabilischen oder mineralischen Fettstoffen durchtränkt werden, worauf ein Glätten der Oberfläche in einer hydraulischen Presse oder in einem Kalander erfolgt, zum Zwecke das auf der Faser ausgefällte Latex so vollständig von der Luft abzuschliessen, dass eine nachträgliche Veränderung desselben während des Lagerns vermieden wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the aftertreatment of synthetic leather panels made from a mixture of rag and cellulose as well as latex as a binder, which is precipitated on the fiber with an acid salt, characterized in that these panels are soaked with animal, vegetable or mineral fatty substances, whereupon the surface is smoothed takes place in a hydraulic press or in a calender, for the purpose of sealing off the latex precipitated on the fiber so completely from the air that a subsequent change of the same during storage is avoided. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
