Description
Patentiert im Deutschen Reiche vom 8. Juli 1903 ab. Längste Dauer: 25. Mai 1918.Patented in the German Empire on July 8, 1903. Longest duration: May 25, 1918.
Das Patent 173878 schützt ein Verfahren des Indigodrucks mittels, stark alkalischer Druckfarben unter gleichzeitiger Anwendung der haltbaren Hydrosulfitverbindungen des Patentes 165280, die eine volle Ausnutzung des Farbstoffs ermöglichen.The patent 173878 protects a process of indigo printing by means of strongly alkaline Printing inks with simultaneous use of the durable hydrosulfite compounds of the Patent 165280, which allow full use of the dye.
Es hat sich aber als Nachteil bei diesem Verfahren herausgestellt, daß eine längere Dämpf dauer im Vergleiche zum Glukosedruck erforderlich ist, wodurch die Produktionsfähigkeit vermindert wird. However, it has been found to be a disadvantage of this method that a longer Steaming time is required in comparison to the glucose pressure, whereby the production capability is reduced.
Es ist nun gefunden worden, daß ein Zusatz von Glukose zur alkalischen Indigohydrosulfitfarbe diesen Übelstand beseitigt, indem hierdurch ohne Beeinflussung der Haltbarkeit der Druckfarbe und ohne Beeinträchtigung der Ausnutzung des Farbstoffs eine ganz wesentliche Verminderung der notwendigen Dämpfdauer erreicht wird. Der Zusatz von Glukose hat auch ferner noch die günstige Wirkung, daß eine geringere Menge der teuereren Formaldehydhydrosulfitverbindung erforderlich ist.It has now been found that adding glucose to the alkaline indigohydrosulfite color this deficiency is eliminated by doing so without affecting the durability of the printing ink and without impairing it the utilization of the dye a very substantial reduction of the necessary Steaming time is reached. The addition of glucose also has that beneficial effect that a smaller amount of the more expensive formaldehyde hydrosulfite compound is required.
Dieser vorteilhafte Einfluß der Glukose ist insofern überraschend, als sich diese bislang als Reduktionsmittel in der Druckfarbe zur Ausnutzung des Indigos nicht geeignet erwies, und es bedurfte daher, um die Glukose für den Indigodruck nutzbar zu machen, der Ausarbeitung eines besonderen umständlichen (des sogenannten Schlieper- Baum sehen) Verfahrens.This beneficial influence of glucose is surprising insofar as it has so far been proved unsuitable as a reducing agent in the printing ink to utilize the indigo, and it was therefore necessary to make glucose usable for indigo printing Elaboration of a special cumbersome (see the so-called Schlieper tree) Procedure.

Verbesserung des Verfahrens des Patentes 173878, dadurch gekennzeichnet, daß man der alkalischen Indigodruckfarbe außer den haltbaren, nach dem Verfahren des Patentes 165280 erhältlichen Hydrosulfitverbindungen, noch Glukose als Reduktionsmittel zusetzt.Improvement of the method of patent 173878, characterized in that one of the alkaline indigo inks besides the durable ones, according to the process of the patent 165280 available hydrosulfite compounds, still adds glucose as a reducing agent.
