Description

Natriumpyrophosphat ist bis jetzt in der Textilchemie als gutes Mittel zum Entfernen von Tintenflecken verwendet worden, indem es bekanntlich mit Eisenverbindungen ein wasserlösliches Doppelsalz bildet.Sodium pyrophosphate has so far been used in textile chemistry as a good removal agent has been used by ink stains by being known to contain iron compounds forms water-soluble double salt.

Es wurde nun die überraschende Beobachtung gemacht, daß pyrophosphorsaure Salze auch gute Waschmittel sind, und besonders, im Gegensatz zur oben erwähnten Tatsache, für gefärbte Gewebe, indem sie die Farben nicht angreifen. Sie eignen sich ganz allgemein zum Waschen und bieten besondere Vorteile für wollene, seidene und andere zarte Gewebe. Auch fettige Faser, wieThe surprising observation has now been made that pyrophosphoric acid Salts are also good detergents, and especially, in contrast to the one mentioned above Fact for dyed fabrics, as they do not attack the colors. You are suitable in general for washing and offer special advantages for woolen, silk and other delicate tissues. Also fatty fiber, like

z. B. Rohwolle, kann mit pyrophosphorsauren Salzen gewaschen werden.z. B. raw wool, can be washed with pyrophosphoric acid salts.

Zum Waschen wollener und seidener Gewebe, die durch Alkalien angegriffen werden, KaT man bereits früher als mild wirkende Waschmittel die alkalischen Salze der Phosphorsäure verwendet. Die Wirkung dieser Verbindungen beruht im wesentlichen auf ihrer Alkalinität, während die Waschfähigkeit der pyrophosphorsauren Salze eine spezielle Eigenschaft dieser Verbindungen ist, die in gewissen Fällen direkt als Emulgierungsmittel wirken.For washing woolen and silk fabrics that are attacked by alkalis, The alkaline salts of phosphoric acid were used earlier as mild detergents used. The effect of these compounds is based essentially on their alkalinity, while the detergency of the pyrophosphoric acid salts is a special property of these compounds, which in act directly as emulsifying agents in certain cases.

Vergleicht man das normale Natriumpyrophosphat Na4P2O7 mit dem dreibasischen Natriumphosphat beim Waschen von Rohwolle, so zeigt sich eine wesentliche Überlegenheit des Pyrophosphats gegenüber dem Phosphat, obgleich das Natriumpyrophosphat eine geringere Alkalinität besitzt. Somit hat man im normalen Pyrophosphat ein Waschmittel, das eine gute Wirkung bereits bei ganz schwach alkalischen Lösungen ausübt. Das Auffallende ist nun, daß auch die Lösungen der sauren Salze von der Zusammensetzung Me2H2P2O7 sich *>zum Waschen eignen, was insofern von großem Vorteil ist, als auf diese Weise das Waschen von zarten Geweben mit neutralen oder sauren Lösungen vorgenommen werden kann. Ein neutrales oder saures Waschmittel wird am einfachsten aus dem normalen Natriumpyrophosphat durch Zugabe von Säuren erhalten.If one compares the normal sodium pyrophosphate Na 4 P 2 O 7 with the tribasic sodium phosphate when washing raw wool, it becomes evident that the pyrophosphate is considerably superior to the phosphate, although the sodium pyrophosphate has a lower alkalinity. Thus, in normal pyrophosphate you have a detergent that has a good effect even with very weakly alkaline solutions. The striking thing is that the solutions of the acid salts of the composition Me 2 H 2 P 2 O 7 are also suitable for washing, which is of great advantage in that it can be used to wash delicate fabrics with neutral or acidic Solutions can be made. A neutral or acidic detergent is most easily obtained from normal sodium pyrophosphate by adding acids.

Die Wirkung der pyrophosphorsauren Salze kann dadurch wesentlich erhöht werden, daß man diese gleichzeitig mit bekannten Wasch- oder Emulgierungsmitteln anwendet, wie z. B. Sulfitablauge, Tragant, Leim, Gelatine, Eiweißstoffe, Saponin, Casein, ,, ferner Salze der verschiedenen Fettsäuren und andere Seifen.The effect of the pyrophosphoric acid salts can be significantly increased as a result, that they are used at the same time as known detergents or emulsifiers, such as B. sulphite waste liquor, tragacanth, glue, gelatin, proteins, saponin, casein, ,, also salts of various fatty acids and other soaps.
