  Verfahren zur Erzielung einer wasserbeständigen Appretur auf   gelatinegetränkten   Stoffen. 



   Die Erfindung bezieht sich auf ein Verfahren zum Unlöslichmachen von Gelatine, um dieselbe auf geschlichtetem Gewebe als ein gegen Wasser und Feuchtigkeit beständiges Appreturmittel verwenden zu können. 
 EMI1.1 
 besonders eignen. 



   Die Gelatine wird beim Trocknen durch   Verflüchtigung   der schwefligen Säure und infolge der Konzentration des Bades gänzlich oder   nur teilweise in   die   unlösliche Form übergeführt.   



  Durch Versuch ist leicht feststellbar, dass beim Kochen obiger Gelatinelösungen unlösliche Gelatine ausgefällt wird. 



   Die Anwendung von   schwefliger Säure   hat überdies den Vorteil, die Farbe des Bichromates zu   ändern.   Die vollständige   Verfüehtigung   dieser Säure beim Trocknen der   Gewebe   hat nicht nur die   Unlöslichmachuug   der Gelatine zur Folge, sondern auch eine   Ausscheidung von Chrom-

   PATENT. ANSPRÜCHE :   I.   Verfahren zur Erzielung iner wasserbeständigen Appretur auf gelatinegetränkten Stoffen, dadurch   gekennzeichnet,   dass zur Überführung der Gelatine in die unlösliche Form ein Alkalibichromat, etwa Kaliumbichromat, in Gegenwart eines Überschusses von schwefliger Säure verwendet wird.

  Process for achieving a water-resistant finish on fabrics soaked in gelatin.



   The invention relates to a method of insolubilizing gelatin in order to be able to use the same on sized fabrics as a finishing agent which is resistant to water and moisture.
 EMI1.1
 particularly suitable.



   During drying, the gelatine is completely or only partially converted into the insoluble form by volatilization of the sulphurous acid and due to the concentration of the bath.



  It can easily be established by experiment that insoluble gelatin is precipitated when the above gelatin solutions are boiled.



   The use of sulphurous acid also has the advantage of changing the color of the bichromate. The complete availability of this acid during the drying of the fabric not only makes the gelatine insoluble, but also causes chromium to be eliminated.
 EMI1.2
 tightness may be. does not affect the water resistance of the fabric.



   The composition of a bath is given here as an example:

    Twines etc. are wrapped with it.



   PATENT. CLAIMS: I. Process for obtaining a water-resistant finish on materials soaked in gelatine, characterized in that an alkali dichromate, such as potassium dichromate, is used in the presence of an excess of sulphurous acid to convert the gelatine into the insoluble form.

2. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass dem Appreturhad gewöhnliche Seife zugesetzt wird, welche durch das C'chromsalz in eine metallische Seife umgewandelt wird, um die Wasserdichtigkeit des Gewebes zu erhöhen. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 2. Embodiment of the method according to claim 1, characterized in that ordinary soap is added to the finishing coat, which is converted into a metallic soap by the chromium salt in order to increase the water resistance of the fabric. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
