Description

  

  Wasch- und     Emulgierungsmittel    und Verfahren zu dessen     Herstellung.       Die     Erfindung    betrifft ein Wasch- und       Emulgierungsmittel    und ein Verfahren zu  dessen Herstellung. Das Wasch- und     Einul-          cierungsmittel    gemäss' der Erfindung kenn  zeichnet sich durch einen Gehalt an normalem       Natriumpyrophosphat.    Es kann besonders für  gefärbte Gewebe, wo es die Farben nicht  angreift, für wollene, seidene     und    andere  zarte Stoffe verwendet werden. Auch fettige  Faser, wie zum Beispiel Rohwolle, kann mit  dem erwähnten     Mittel    gewaschen werden.  



  Zum Waschen wollener und seidener Ge  webe, die durch Alkalien angegriffen wer  den, hat man bereits früher als mild wir  kende Waschmittel die alkalischen Salze  der Phosphorsäure verwendet.  



  Vergleicht man das normale     Natriumpyro-          phosphat        Na4P20,    mit dem dreibasischen       Natriumphosphat    beim Waschen von Roh  wolle, so zeigt sich eine wesentliche Über  legenheit des     Natriumpyrophosphates    gegen  über dem dreibasischen Phosphat, obgleich  das     Natriumpyrophosphat    eine geringe     Al-          kalinität    besitzt.

   Ein Vergleich zwischen       Natriumpyrophosphat    und dem zweibasischen         Natriumphosphat,    die ungefähr     gleichstark     alkalisch wirken, ergibt, dass zur Erzielung  des gleichen Wascheffektes eine mehrfache  Menge von sekundärem     Natriumphosphat     erforderlich ist.  



  Zur Herstellung des vorliegenden     Wasch-          und        Emulgierungsmittels    verfährt man  zweckmässig derart,, dass     Natriumpyrophos-          phat    trocken mit einer sauer     wirkenden     Verbindung, zum Beispiel     Natriumbisulfat,     vermengt     wird.     



  Die Wirkung des Wasch- und     Emulgie-          rungsmittels    gemäss der vorliegenden Erfin  dung kann dadurch wesentlich erhöht wer  den, dass man ihm     gleichzeitig,    ein anderes  bekanntes Wasch- oder     Emulgierungsmittel     beifügt,     wie    zum Beispiel     Sulfit-Ablauge,          Tragant,    Leim, Gelatine, Eiweissstoffe,     Sa-          ponin,    ferner Salze der verschiedenen Fett  säuren und andere .Seifen.



  Detergents and emulsifiers and process for their production. The invention relates to a detergent and emulsifier and a method for its production. The detergent and emulsifying agent according to the invention is characterized by a content of normal sodium pyrophosphate. It can be used especially for dyed fabrics, where it does not attack the colors, for woolen, silk and other delicate fabrics. Greasy fibers, such as raw wool, can also be washed with the agent mentioned.



  For washing woolen and silk fabrics that have been attacked by alkalis, the alkaline salts of phosphoric acid have already been used as mild detergents.



  If one compares the normal sodium pyrophosphate Na4P20 with the tribasic sodium phosphate when washing raw wool, it becomes evident that sodium pyrophosphate has a significant superiority over tribasic phosphate, although sodium pyrophosphate has a low alkalinity.

   A comparison between sodium pyrophosphate and the dibasic sodium phosphate, which have approximately the same alkaline effect, shows that a multiple amount of secondary sodium phosphate is required to achieve the same washing effect.



  To prepare the present detergent and emulsifying agent, the procedure is expediently such that sodium pyrophosphate is mixed dry with an acidic compound, for example sodium bisulfate.



  The effect of the detergent and emulsifier according to the present invention can be increased significantly by adding another known detergent or emulsifier, such as sulphite waste liquor, tragacanth, glue, gelatine, proteins, Saponine, also salts of various fatty acids and other soaps.
