  Verfahren zum Löslichmachen unlöslicher Gummiarten, Algen, Flechten u. s. w. 



   Wie im Stammpatent gezeigt wurde, lassen sich Perborate mit Vorteil zum Löslichmachen von   Stärken   verwenden. 



   Durch weitere Untersuchungen wurde gefunden, dass man die Reaktion auch auf andere, der Stärke ähnliche Körper ausdehnen kann. Dies betrifft die im Wasser unlöslichen Gummiarten, Algen und Flechten, welche durch geringe Mengen Perborat sehr leicht in Lösung gebracht werden kann. Diese Produkte bilden wichtige Handelsartikel und sind im Verkehr unter den Bezeichnungen ostindischer Gummi, Basseringummi, unlöslicher Gummi usw. be-   kannt. Auch   bezieht sich die Verwendung von Perborat auf Traganth, Agar-Agar,   Caragheen-   moos,   isländisches   Moos usw. 



   Die meisten dieser Naturprodukte werden als Verdickungen in der Druckerei und Appretur verwendet. Man lässt sie in kaltem Wasser quellen und kocht dann meist unter   erhöhtem   Druck 10-12 Stunden. Man hat für eine der oben genannten Substanzen, für das Agar-Agar bereits versucht, durch Ozon eine Erhöhung der   Löslichkeit herbeizuführen.   



  Indessen ist dieser Weg ein recht kostspieliger und für diejenigen Fabriken, welche als Verbraucher der unlöslichen Gummis in erster Linie in Frage kommen, nämlich die Textil- 
 EMI1.1 
 verfügen. Das angemeldete Verfahren liegt dagegen vollkommen im Rahmen der üblichen   Tätigkeit der Textilfabriken,   indem die Behandlung der Gummis mit Flüssigkeiten gar keine Schwierigkeiten bereitet, und ausserdem der   zurückbleibende Borax   die Verwendung 
 EMI1.2 
 lung mit Perborat wird die Kochdauer wesentlich verkürzt und gleichzeitig ein bedeutend löslicheres Endprodukt erzielt. 



   Man verwendet das Perborat in der Weise, dass man die   Gummiarten   bereits in einer   Ptwboratlösung aufquellen   lässt und dann unter weiterem Wasserzusatze kocht, bis man Lösungen von gewünschter Konzentration erhält. Im Allgemeinen genügt bereits 1% Perborat vom Gewichte des angewendeten Gummi.

  Process for solubilizing insoluble gums, algae, lichens and the like s. w.



   As shown in the parent patent, perborates can be used to advantage to solubilize starches.



   Further research has shown that the response can be extended to other bodies similar in strength. This applies to the types of rubber, algae and lichens that are insoluble in water and which can very easily be dissolved with small amounts of perborate. These products are important commercial articles and are known in the trade under the names of East Indian rubber, basing rubber, insoluble rubber, etc. Also, the use of perborate relates to tragacanth, agar-agar, caragheen moss, Icelandic moss, etc.



   Most of these natural products are used as thickening in printing and finishing. They are left to soak in cold water and then usually boiled under high pressure for 10-12 hours. For one of the substances mentioned above, for agar-agar, attempts have already been made to bring about an increase in solubility by means of ozone.



  However, this route is a very expensive one and for those factories which are primarily the consumers of the insoluble gums, namely the textile
 EMI1.1
 feature. The process applied for, on the other hand, lies entirely within the framework of the normal activity of the textile mills, in that the treatment of the rubbers with liquids poses no difficulties at all, and the use of the borax that remains is not a problem
 EMI1.2
 Treatment with perborate significantly shortens the cooking time and at the same time results in a significantly more soluble end product.



   The perborate is used in such a way that the types of gums are already swollen in a Ptwboratlösung and then boiled with further addition of water until solutions of the desired concentration are obtained. In general, 1% perborate of the weight of the rubber used is sufficient.
