Description
Die Reinigung von Geweben mit Wasserglas oder viel Wasserglas enthaltenden Wasch-' mitteln verursacht Nachteile; die Faser wird allmählich krümelig und spröde, die Gewebe bekommen j ei nach dem Grade und der Häufigkeit des Auswäschens ein faseriges Aussehen und einen rauhen Griff, sie werden brüchig, und ihre Haltbarkeit leidet im Laufe der Zeit beträchtlich.The cleaning of fabrics with water glass or washing machines containing a lot of water glass medication causes disadvantages; the fibers gradually become crumbly and brittle, the tissues get a fibrous appearance depending on the degree and frequency of washing and a rough handle, they become brittle and their durability suffers over time considerably.
ίο Das beruht nicht nur auf der starken Alkalität des Wasserglases im Waschbade, sondern in noch weit höherem Maße auf der nachträglichen mechanischen. Wirkung der infolge der Hydrolyse in der Faser zurückbleibenden Kieselsäure sowie des beim Trocknen ' der Faser entstehenden spröden Überzuges von Alkalisilikat.' Das vollständige Heraus-' waschen dieser Stoffe aus dem Gewebe ist mit Schwierigkeiten verknüpft und wurde bisher im allgemeinen nicht erreicht.ίο This is not only due to the strong alkalinity of the water glass in the wash bath, but to an even greater extent on the subsequent mechanical. Effect of those remaining in the fiber as a result of hydrolysis Silicic acid as well as the brittle coating formed during drying of the fiber of alkali silicate. ' The complete out- ' washing these substances from the fabric is associated with difficulties and has been so far generally not achieved.
Es wurde' nun gefunden, daß diese Nachteile vermieden werden, wenn man die mit Wasserglas gewaschenen Gewebe mit einer verdünnten Lösung von Ammoniumchlorid oder dem Ammonsalz einer anderen starken Säure nachspült. So wurden Gewebe, welche nach dem Waschen mit starker Wasserglaslösung und nach gewöhnlichem Ausspülen auf den menschlichen Körper einen unerträglichen Reiz ausübten, durch kurzes Nachspülen in Salmiaklösung in brauchbaren Zustand übergeführt. Bei der mikroskopischen Prüfung der mit Ammonsalzlösung nachgespülten Faser konnte vielfach eine wesentlich geringere Menge anhaftender Kristalle beobachtet werden als bei einem nur in Wasser ausgespülten Gewebe. Vielleicht beruht diese Wirkung der Ammonsalze darauf, daß sie die Kieselsäure in einem besonders leicht auswaschbaren Zustande ausfällen. Zugleich werden auch .alle anderen alkalisch reagierenden, nicht flüchtigen Stoffe, welche hartnäckig an der Faser haften und dem Auswaschen Widerstand entgegensetzen, durch die Ammonsalze in leicht aus dem Gewebe entfernbare Verbindungen verwandelt.It has now been found that these disadvantages are avoided by using the Water glass washed tissue with a dilute solution of ammonium chloride or the ammonium salt of another strong acid. So tissues became which after washing with strong water glass solution and after ordinary rinsing exerted an unbearable stimulus on the human body by briefly rinsing in Salmia solution converted into usable condition. During the microscopic examination the fibers that were rinsed with ammonium salt solution often had a significantly lower level The amount of adhering crystals can be observed than with one only in water rinsed tissue. Perhaps this effect of the ammonium salts is due to the fact that they have the Precipitate silica in a particularly easily washable state. Simultaneously will also .all other alkaline reacting, non-volatile substances, which are stubborn adhere to the fiber and resist washing out by the ammonium salts transformed into connections that can be easily removed from the tissue.
