Zusatz zum Patent 290605.Addendum to patent 290605.
Patentiert im Deutschen Reiche vom 30. Juni 1914 ab. Längste Dauer: 26. Januar 1929.Patented in the German Empire on June 30, 1914. Longest duration: January 26, 1929.
Nach dem Verfahren des Patents 290605 wird ein Ersatzstoff für Flachs,. Hanf und Jute aus Cyperus papyrus dadurch erhalten, daß man die Papyrusstauden in noch nicht völlig ausgetrocknetem Zustande zur Aufschließung der schwach geholzten Fasern mit siedendem Wasser, gegebenenfalls unter Druck, behandelt und sie schließlich zur Beseitigung der Sprödigkeit mit Fetten oder ähnlich wirkenden Stoffen imprägniert.Using the method of patent 290605, a substitute for flax is made. Hemp and Jute from Cyperus papyrus obtained by not cutting the papyrus bushes in yet completely dried out condition to break down the weakly wooded fibers boiling water, possibly under pressure, treated and finally disposed of the brittleness impregnated with grease or similar acting substances.
Weitere Versuche haben zu dem Ergebnis geführt, daß das Verfahren dadurch abgekürzt werden kann, daß man die Stauden, frisch geerntet, durch eine kräftige Presse gehen läßt und in ihr das Wasser bis auf etwa 5 Prozent entfernt. Sind die Stengel nicht mehr genügend feucht, so sind sie vor dem Pressen in Wasser einzuweichen. Durch das starke Pressen der feuchten Stauden wird erreicht, daß die Parenchymzellen durch Platzen deformiert werden und sich durch mechanische Behandlung von den Baststrängen leicht trennen lassen. Durch diese Behandlungsweise wird die nachfolgende Behandlung mit heißem Wasser unter Druck wesentlich abgekürzt und zugleich eine bessere und haltbarere Ware erzielt. Further attempts have led to the result that the process is shortened as a result the perennials, freshly harvested, can be put through a powerful press leaves and removes the water in it down to about 5 percent. Are not the stalks if they are more sufficiently moist, soak them in water before pressing. By the strong pressing of the moist perennials is achieved that the parenchymal cells burst through are deformed and easily separate from the bast strands by mechanical treatment permit. This treatment makes the subsequent treatment with hot Water significantly shortened under pressure and at the same time a better and more durable product was achieved.
