   Demnach kennzeichnet sich die vorliegend beschriebene Bastgewinnung im Gegensatze zu jener nach dem französischen Patente Nr. 388874 durch die unmittelbare mechanische Entfernung der ausserhalb der Bastfaserschichte befindlichen Substanzen, und zwar ;
1. Entbasten auf der Rute entweder unmittelbar oder nach erfolgter Vorbehandlung der Rute. 



   2. Entbasten von der vom Holze bereits losgelösten Rinde entweder unmittelbar oder nach erfolgter Vorbehandlung der Rute wie unter 1. 



   Die Aufschliessungsvorgänge zur Isolierung und Freilegung des Bastes zur   Gewinnung clefs     Fasergutes erfolgen in nachstehender Weise:

 EMI3.1 
 



   Zum Zwecke der Entfernung der beim Aufschliessen des Bastes bemerkbaren dunklen Baststellen und   vorkommenden   Oberhautteilehen der Rinde, ist der Bast vorher in geeigneter Weise zu putzen ; die rostbraunen Baststellen sind durch Ausschneiden zu entfernen. 



   Bei   Baststreifen   mit anhaftender Oberhaut kann die Entfernung der Oberhautteilchen

 folgtem Trocknen des aufgeschlossenen Fasergutes durch Auflockern, Schütteln, Klopfen und
Kämmenvorgenommenwerden. 



   Die Aufschliessung kann durch   geeignete Lösungsmittel unterstützt   oder   durch   Anwendung maschineller Vorrichtungen so beschleunigt werden, dass die Gewinnung des Fasergutes in kurzer
Zeit erfolgt. 



   Die besondere Feinheit und dichte Anordnung der Maulbeerfaser, die Länge der Einzelzelle   ) (his 30 ìnm)   und ihre leichte Isolierbarkeit lassen es zweckmässig erscheinen, die parallele An- ordnung der Zellverbände und Einzelzellen während des Aufschliessungsvorganges unbeschadet zuerhalten. 



   PATENT. ANSPRÜCHE : 
1.   Verfahren   zur Gewinnung der in den   Maulbeergewächsen, speziell m Morus alba.   der weissen   Maulheere, enthaltenen   Bastfasern, dadurch gekennzeichnet, dass man entweder unmittelbar oder nach Vorbehandlung die Oberhaut und die Zwischensubstanzen von der Rute entfernt. den Bast vom Holze   loslöst   und den so erhaltenen Rohbast weiter aufschliesst oder die basthältige Rinde unmittelbar oder nach Vorbehandlung vom Holze lostrennt, die Oberhaut-und Zwischensubstanzen entfernt und den so erhaltenen Rohbast weiter aufschliesst, oder die Oberhaut- und Zwischensubstanzen während des Aufschliessungsvorganges oder nach demselben entfernt.

 or wet ways and then mechanical processing by knocking, rubbing, corrugating, stamping or other effects.



   Accordingly, the bast extraction described here, in contrast to that according to French patent no. 388874, is characterized by the direct mechanical removal of the substances located outside the bast fiber layer, namely;
1. Deboning on the rod either immediately or after the rod has been pre-treated.



   2. Deboning of the bark that has already been detached from the wood either immediately or after pretreatment of the rod as under 1.



   The digestion processes to isolate and expose the bast to obtain clefs fiber material are carried out in the following way:

 <Desc / Clms Page number 3>

 
 EMI3.1
 



   For the purpose of removing the dark areas of the bast and the epidermis of the bark that are noticeable when opening the bast, the bast must be cleaned beforehand in a suitable manner; the rust-brown bast areas are to be removed by cutting out.



   In the case of strips of bast with adherent epidermis, the epidermal particles can be removed
 EMI3.2
 subsequent drying of the broken down fiber material by loosening, shaking, tapping and
Combing can be done.



   The digestion can be supported by suitable solvents or accelerated by using mechanical devices so that the fiber material can be obtained in a short time
Time takes place.



   The particular fineness and dense arrangement of the mulberry fibers, the length of the individual cells (up to 30 ìnm) and their ease of isolation make it useful to keep the parallel arrangement of the cell structures and individual cells undamaged during the digestion process.



   PATENT. EXPECTATIONS :
1. Process for the extraction of those in the mulberry family, specifically m Morus alba. the bast fibers contained in the white mouth, characterized in that either immediately or after pretreatment, the epidermis and the intermediate substances are removed from the tail. detaches the bast from the wood and further breaks down the raw bast obtained in this way, or separates the bark containing bast from the wood immediately or after pretreatment, removes the epidermis and intermediate substances and further breaks down the raw bast obtained in this way, or the epidermis and intermediary substances during or after the digestion process away.
