Description

Verfahren zum Rösten von Flachs Bei allen zur Zeit gebräuchlichen Flachsröstmethoden muß der rohe Flachs ins Wasser gelegt werden. Dies Verfahren hat große Nachteile, erstens wird der Flachs mißfarben, zweitens ist die nachherige Trocknung nicht einfach und auch nicht billig.Method of roasting flax With all currently in use Flax roasting methods, the raw flax must be placed in the water. This procedure has great disadvantages, firstly the flax is discolored, secondly is the one afterwards Drying is not easy and also not cheap.

Die vorliegende Erfindung ist geeignet, diese L'belstände zu beseitigen. Sie beruht auf der neuen Erkenntnis, daß die Röstung von Flachsfasern aus Rohflachs unter Entfernung der natürlichen Begleitkörper der Flachsfasern durch Behandlung derselben mit künstlichen ultravioletten Strahlen in einer feuchten Atmosphäre in der Art erfolgen kann, daß die Flachsfasern in rohem Zustande behandelt werden.The present invention is suitable for eliminating these debris. It is based on the new knowledge that the roasting of flax fibers from raw flax with removal of the natural accompanying bodies of the flax fibers by treatment same with artificial ultraviolet rays in a humid atmosphere in can be done in such a way that the flax fibers are treated in the raw state.

Erfindungsgemäß wird der geerntete Flachs in dünnen Schichten ausgebreitet, durch eine Vorrichtung feucht gehalten und künstlichen ultravioletten Strahlen ausgesetzt. Das bei diesem Verfahren auftretende Ozon wirkt als Hilfsmittel zur Erreichung des neuen technischen Effektes. Hierbei wird die Epidermis gelockert und gesprengt, ebenso die Mittellamelle. Bei der nachherigen Bearbeitung «-erden die Pflanzenteile, welche die Flachsfasern umgeben, in einer Knickmaschine mit den verkittenden Substanzen zusammen abgestoßen, und die Flachsfaser erscheint in ihrer natürlichen Reinheit, Farbe und Reißfestigkeit. Ein gegebenenfalls nachher vorzunehmender Bleichprozeß erfordert nur ganz geringe Mengen der bleichenden Substanz, so daß auch hier fast kein Verlust entsteht.According to the invention, the harvested flax is spread out in thin layers, kept moist by a device and exposed to artificial ultraviolet rays. The ozone occurring in this process acts as an aid to achieve the new technical effect. Here, the epidermis is loosened and burst, likewise the middle lamella. During the subsequent processing "- earth the parts of the plant, which surround the flax fibers, in a kinking machine with the cementing substances repelled together, and the flax fiber appears in its natural purity, Color and tear resistance. A bleaching process to be carried out afterwards if necessary requires only very small amounts of the bleaching substance, so that here too almost there is no loss.

Man hat bereits vorgeschlagen, beim Trocknen von gebleichten Leinenfasern ultraviolette Strahlen anzuwenden. Ein derartiges Verfahren hat mit dem vorliegenden nichts gemein. -Es geschah, um die Leinenfasern vor dem 'Viederanfärben, besonders mit Chlorophyll, und somit vor dem Verderben des Weiß zu schützen.It has already been suggested that bleached linen fibers be used in drying to apply ultraviolet rays. Such a method has with the present nothing in common. -It happened to the linen fibers before 'viederinfärben, especially with chlorophyll, and thus to protect against the spoilage of the white.
