 EMI1.1 
 



   Es ist bekannt, aus   Schilf eine Fa- ! er für   die verschiedensten technischen Zwecke zu gewinnen. Das Verfahren besteht im wesentlichen   darin, dass   die Pflanze mit alkalischen Laufen behandelt wird, um sie aufzuschliessen. Die durch   das Aufschliessen   gewonnene   Faser wird schliesslich   mit Säuren verschiedener Art behandelt, gespült und getrocknet. Die so gewonnene Faser zeigt jedoch noch den   Übelstand, dans   die 
 EMI1.2 
 enthaltenen Klebe eine Schlichte bildet.   welche verursacht, dass immer   mehrere Fasern zusammenkleben. 



  Die Schlichte liess sich bisher nicht entfernen, ohne dass die Faser   angegriffen wurde. \Vollte   man die Schlichte durch Behandeln der   Faser mit Säure entfernen, so würde die Faser durch die Säure zu   stark angegriffen und in ihrer Beschaffenheit beeinträchtigt. 



   Gemäss der vorliegenden Erfindung wird nun die Schlichte in der Weise entfernt, dass man die 
 EMI1.3 
 Säure behandelt, derart, dass die Fasern hiebei nicht leiden. Nach Spülen der Fasern   behufs     der Entfernung   der Säure erfolgt akdann die Behandlung, wie oben angegeben, mit diastatischen Präparaten. 



   Man hat zwar bereits vorgeschlagen, rohe Pflanzenfasern einer Vorbehandlung in einem verdünnten alkalischen Bade und einer nachfolgenden Behandlung mit einer schwach alkalischen   Enzymlösung   zu unterwerfen. Dieses Verfahren ist jedoch mit diastatischen Präparaten nicht ausführbar, da ein Bad,   melehes   letztere enthält, von Alkalien völlig frei sein muss, damit die oben beschriebene Wirkung der diastatischen Präparate eintritt.

 EMI1.1
 



   It is known to make a fa-! he can be won for various technical purposes. The process essentially consists of treating the plant with alkaline runs in order to break it down. The fiber obtained through the digestion is then treated with various types of acids, rinsed and dried. However, the fiber obtained in this way still shows the drawback, dans the

 contained adhesive forms a size. which causes several fibers to stick together.



  Up to now, the size could not be removed without attacking the fiber. \ If the size is removed by treating the fiber with acid, the fiber would be too strongly attacked by the acid and its quality would be impaired.



   According to the present invention, the size is now removed in such a way that the

 Treated with acid in such a way that the fibers do not suffer. After the fibers have been rinsed to remove the acid, treatment is then carried out, as indicated above, with diastatic preparations.



   It has already been proposed to subject raw vegetable fibers to a pretreatment in a dilute alkaline bath and a subsequent treatment with a weakly alkaline enzyme solution. However, this method cannot be carried out with diastatic preparations, since a bath containing melehes of the latter must be completely free of alkalis for the above-described effect of the diastatic preparations to occur.
