   Beispiel 3 : Die nach Beispiel 1 hergestellte   Kupferoxydammoniak-Fibroinlösung   wird mit dem doppelten Volumen 15%iger Ammonsulfatlösung versetzt ; nach der Koagulation des   Fibroins   in Form einer dunkelblauen Paste wird die überstehende Lösung sofort abgegossen, die Paste   gut ausgedrückt   und wie in Beispiel 1 unter Rühren gelöst. 



   Beispiel 4 : In die nach Beispiel 1 hergestellte Kupferoxydammoniak-Fibroinlösung wird CO2

   Example 3: The copper oxide ammonia fibroin solution prepared according to Example 1 is mixed with twice the volume of 15% ammonium sulfate solution; After the fibroin has coagulated in the form of a dark blue paste, the supernatant solution is poured off immediately, the paste is squeezed out well and dissolved as in Example 1 with stirring.



   Example 4: CO2 is added to the copper oxide ammonia fibroin solution prepared according to Example 1
 EMI1.3
 is partly bound.
