Description
Verfahren zum Rösten, Aufschließen und Kotonisieren vegetabilischer Rohstoffe zwecks Gewinnung von Langfasern und kotonisierten Fasern oder von Papierstoff. Im Hauptpatent ist ein Verfahren beschrieben, bei dein zwecks Aufschließung vegetabilischen Rohhutes zur Gewinnung von Langfasern oder kotonisierten Fasern oder Papierstoff das Rohgut l:ei Gegenwart von Wasser mit unlöslichen oder schwerlöslichen Oxvden oder Hvdroxvden der Erdalkali- oder hrdnietalle ltehande lt wird. Hierbei werden die Inkrusten verändert, und zwar, wie es scheint, im wesentlichen in physikalischer Beziehung, so laß sie nach der Behandlung aus dem Gut leicht durch Auswaschen oder auskämmen entfernt «-erden können. Die Gegenwart von \\'asser ist notwendig und scheint im wesentlichen durch Quellung der Inkrusten die physikalische Ein-,virkung der unlöslichen Körper auf diese vorzubereiten. Es wurde nun gefunden, daß außer Wasser in gleicher Weise andere wässerige Flüssigkeiten wirken und je nach dem Rohmaterial mit Vorteil angewendet werden können. Derartige Flüssigkeiten sind- dünne, wässerige Alkalilaugen, Lösungen von Alkalikarbonaten. neutralen oder sauren Stilfiten, Seifen, wie beispielsweise Türkischrotöl u. dgl. auch diese scheinen wie das Wasser gemäß dein Hauptpatent: quellend auf die Inkrusten zu wirken und dadurch die Einwirkung der unlöslichen :aufschließungsmittel vorzubereiten. Das Verfahren soll im folgenden an einem Beispiel erläutert werden.Process for roasting, digesting and cotonizing vegetables Raw materials for the production of long fibers and cottonized fibers or paper stock. In the main patent, a process is described with your vegetable for the purpose of opening up Raw hat for the production of long fibers or cottonized fibers or paper stock the raw material l: in the presence of water with insoluble or sparingly soluble oxides or Hvdroxvden the alkaline earth or hard rivets are all handled. Here will be the incrustations changed, and it appears to have been essentially physical Relationship, so leave it after the treatment from the property easily by washing out or comb out removed «-earth. The presence of \\ 'ater is necessary and The physical effect appears to be essentially through swelling of the incrustations prepare the insoluble bodies for this. It has now been found that besides Water act in the same way other aqueous liquids and depending on the raw material can be used with advantage. Such liquids are thin, watery Alkaline solutions, solutions of alkali carbonates. neutral or acidic stilettos, soaps, such as Turkish red oil and the like, these also seem like the water in accordance with your main patent: to act swelling on the incrustations and thereby the effect the insoluble: prepare disintegrating agents. The procedure is intended in the following will be explained using an example.
5oo Teile Flachswerg (von- Scheben befreit) werden mit 5 Teilen geglühtem 1lagnesit und 5ooo Teilen einer dünnen Natronlauge 2 Stunden auf 12o° im Autoklaven erhitzt. Das Produkt wird sodann ausgewaschen, getrocknet und gekämmt.500 parts of Flachswerg (freed from flakes) are annealed with 5 parts 1lagnesite and 500 parts of a thin sodium hydroxide solution for 2 hours at 120 ° in the autoclave heated. The product is then washed, dried and combed.
