   Kunstleder wird meist aus Stoffbahnen hergestellt, indem diese mit Lösungen von Nitrozellulose, Zelluloid oder Azetylzellulose, gemengt mit Farbstoffen und Zusätzen weich haltender Art. imprägniert werden. Die Stoffbahnen werden zweckmässig in einer Farbe gefärbt, die der der Imprägnierungsschichte gleich oder nahe kommt, welche nach Färbung der Stoffbahnen auf diese aufgetragen wird. 



   Es hat sich nun gezeigt, dass zur Erzielung einer   Färbung des Kunstleders nicht   die Nitrozelluloseschichte durch Vermischung mit Pigmentfarbstoffen gefärbt werden muss, ehe sie auf die Stoffbahn aufgetragen wird, sondern, dass die Färbung der Schichte auch nach Imprägnieren der Stoffbahn mit farbloser Nitrozellulose oder Zelluloidschichte vorgenommen werden kann. In diesem Falle ist es aber notwendig, der Schichte deckende Stoffe einzuverleiben. die sich gleich-

 EMI1.1
 



   Artificial leather is usually made from lengths of fabric by impregnating them with solutions of nitrocellulose, celluloid or acetyl cellulose, mixed with dyes and additives that keep them soft. The lengths of fabric are expediently dyed in a color that is the same or close to that of the impregnation layer which is applied to the lengths of fabric after it has been colored.



   It has now been shown that in order to achieve a coloring of the artificial leather, the nitrocellulose layer does not have to be colored by mixing it with pigment dyes before it is applied to the fabric, but that the coloring of the layer also takes place after the fabric is impregnated with colorless nitrocellulose or celluloid can be. In this case, however, it is necessary to incorporate substances that cover the layer. which are equal
