Description

Verfahren zur Gewinnung verspinnbarer Fasern aus Bastfaserpflanzen Seit alters her gewinnt man nach langwierigen Röstverfahren solche verspinnbare Fasern. Chemische Versuche, die unlösliche Pektose in die zum größten `feil löslichen Pektinstoffe zu verwandeln, sind bisher fehlgeschlagen und nur durch die bekannten Röstverfahren zu erreichen.Process for obtaining spinnable fibers from bast fiber plants Since time immemorial, spinnable ones have been made after lengthy roasting processes Fibers. Chemical attempts to convert the insoluble pectosis into those that are largely soluble Converting pectin substances have so far failed and only through the known ones To achieve roasting process.

Die Erfindung bezieht sich auf die chemische Aufschließung des Turbinenhechelwerges und ist auch für den Aufschluß von Thyphafasern sowie von Weidenrinde und anderen Bastfasern vorteilhaft anzuwenden.The invention relates to the chemical digestion of the Turbinenhechelwerges and is also used for the digestion of thypha fibers as well as willow bark and others Advantageously to use bast fibers.

Aus der Erkenntnis heraus, daß u. a. der menschliche Körper die aufgenommenen Speisen abwechselnd sauer, alkalisch, sauer auflöst bzw. zersetzt, wurde folgendes zum Teil kontinuierliches Verfahren gefunden, um Faserpflanzen in kürzester Zeit bei schonerster Behandlung und geringstem Dampfverbrauch chemisch aufzuschließen. Es besteht darin, daß das gebrochene und geschwungene Gut abwechselnd sauer, alkalisch, sauer behandelt und nach Eintauchen in eine Lauge und Abquetschen weit unter Kochtemperatur des Wassers im Vakuum gedämpft wird, worauf die gelösten Pektine bzw. Leimstoffe abgespült werden.From the knowledge that inter alia the human body the ingested Food alternately acidic, alkaline, acidic dissolves or decomposes, became the following partly continuous process found to fiber plants in a very short time to be chemically digested with the gentlest treatment and the lowest steam consumption. It consists in the fact that the broken and curved goods are alternately acidic, alkaline, Treated acidic and after dipping in a lye and squeezing off, well below the boiling temperature of the water is steamed in a vacuum, whereupon the dissolved pectins or glue substances be rinsed off.

Das besonders mechanisch intensiv vorbehandelte Material wird bei 5o' C io Minuten lang im sauren Medium (5 ccm konz. techn. Schwefelsäure, etwa 92 o/oig pro Liter) oder i 5,ccm konz. techn. Salzsäure (37 o/oig pro Liter Flotte) behandelt und abgequetscht, anschließend in eine Lauge (io g Ätznatron pro Liter, Behandlungsdauer etwa io Minuten bei normaler Wassertemperatur, Verlust an Ätznatron pro Liter Flotte etwa 2,7 g) getaucht, abgequetscht und im Vakuum weit unter Kochtemperatur des Wassers (i bis 2 Std. bei o,6o Atm. und 5o° C) gedämpft. Im Anschluß daran wird bei 70° C gespült und in Anwesenheit eines Waschmittels bei Beibehaltung der Temperatur in den folgenden Bädern bei intensiver Flottenbewegung gewaschen bzw. werden die gelösten Pektinstoffe abgeschwemmt. Im Spüllbad gibt man io ccm Salzsäure pro Liter Flotte hinzu und behandelt bei 7o° C ioMinuten wiederum bei heftigerFlottenbewegung mittels eingeblasener Luft. Ein leicht gekräuseltes, sehr helles und gesundes Material fällt an.The material, which is mechanically intensively pretreated, is used in In an acidic medium (5 ccm conc. Technical sulfuric acid, approx. 92%) for 50 '10 minutes o / oig per liter) or i 5 ccm conc. techn. Hydrochloric acid (37% per liter of liquor) treated and squeezed, then in a lye (10 g caustic soda per liter, Treatment time about 10 minutes at normal water temperature, loss of caustic soda per liter of liquor about 2.7 g) dipped, squeezed and in a vacuum well below boiling temperature of the water (1 to 2 hours at o, 6o atm. and 5o ° C) steamed. Following this will Rinsed at 70 ° C and in the presence of a detergent while maintaining the temperature in the following baths with intensive liquor agitation or the dissolved pectins washed away. In the rinsing bath you add 10 cc Hydrochloric acid was added per liter of liquor and treated again at 70 ° C. for 10 minutes violent fleet movement by means of blown air. A slightly ruffled, very light and healthy material is obtained.
