Description

Verfahren zum Überführen von Naturseidefäden in eine kolloide Lösung Es ist bekannt, natürliche Seide (Fibroin) mittels leicht löslicher Magnesiumsalze und anschließender Ausscheidung der Magnesiumsalze in eine kolloide Lösung überzuführen, aus welcher künstliche Seidefäden hergestellt <<-erden.Process for converting natural silk threads into a colloidal solution It is known to make natural silk (fibroin) by means of easily soluble magnesium salts and subsequent excretion of the magnesium salts in a colloidal solution, from which artificial silk threads are made << - earth.

Bei Verwendung eines Magnesiumsalzes bereitet es .erhebliche Schwierigkeiten, das Salz restlos aus der kolloiden Lösung zu entfernen. Das Verbleiben von Magnesiumsalzen in der kolloiden Lösung führt zu :dem schwerwiegenden Nachteil, daß die Seide nach und bei der Bildung der Fäden brüchig wird. Durch Verwendung einer Magnesiumchloridlösung z. B. wird die Überführung des Naturseidefad;ens in den flüssigen kolloiden Zustand allmählich fortgesetzt; hierdurch tritt jedoch eine wesentliche Veränderung des Fibroins ein. Wenn daher Seidefäden künstlich aus der Kolloi@dlösung gesponnen werden, die durch Verwendung von Magnesiumchlorid hergestellt wurde, fehlt es den gesponnenen Fäden an Zähigkeit undWiderstandsfähigkeit. Diese Fäden können daher nicht industriell verwertet werden.When using a magnesium salt, it causes considerable difficulties to remove the salt completely from the colloidal solution. Remaining magnesium salts in the colloidal solution leads to: the serious disadvantage that the silk after and becomes brittle as the threads form. By using a magnesium chloride solution z. B. is the conversion of the natural silk thread into the liquid colloid state gradually continued; however, this results in a significant change in the Fibroins a. If, therefore, silk threads are artificially spun from the colloid solution, which was made by using magnesium chloride is missing the spun Threads of toughness and resilience. These threads can therefore not be used industrially be recycled.

Nach der Erfindung werden die N aturseidefäden mittels einer Magnes,iumnitratlösung in eine Kolloidlösung; überführt. Erst bei Verwendung einer Magnesiumnitratlösung zum Auflösen der Naturseidefäden ist es möglich, das Magnesiumsalz bis auf die geringste Spur aus der kolloiden Lösung zu entfernen. Durch Verwendung der Magnesiumnitratlösung kann man jedoch nicht nur das Magnesiumsalz aus der kolloiden Lösung nach der Verflüssigung des N aturseidefadens leicht und schnell entfernen, sondern man erreicht auch ohne wesentliche Veränderung des Pibroins eine restlose Überführung der Naturs.eidefäden in den kolloiden flüssigen Zustand. Daher sind die aus dieser kolloiden Lösung gesponnenen Seidefäden sehr zäh und widerstandsfähig, so daß sie, für alle Verwendungszwecke verwertet werden können.According to the invention, the natural silk threads are made of a magnesium nitrate solution in a colloid solution; convicted. Only when using a magnesium nitrate solution To dissolve the natural silk threads, it is possible to use the magnesium salt down to the slightest Remove trace from the colloidal solution. By using the magnesium nitrate solution However, you can not only get the magnesium salt from the colloidal solution after liquefaction of the natural silk thread can be easily and quickly removed, but can also be reached without Significant change in the pibroin, a complete transfer of natural silk threads in the colloidal liquid state. Hence the ones spun from this colloidal solution Silk threads are very tough and resistant, so they can be used for all purposes can be recycled.

Als Ausführungsbeispiel -der Erfindung werden ungefähr zehn Teile Magnesiumnitrat in fünf Teilen Wasser aufgelöst. Diese Lösung wird auf eine Temperatur von etwa iio° C erwärmt. Dann werden zwei oder drei Teile Seidenabfälle nach und nach in kleinen Mengen zu der Magnesiumnitratlösun.g hinzugefügt, die behutsam umgerührt wird. Unter Bildung einer kolloiden Lösung werden hierbei die Seidenabfälle (Naturrohseidefäden, alte Seidengewebe) flüssig gemacht. Das Magnesiumsalz wird dann aus der kolloiden Lösung durch Dialyse oder ein anderes übliches Abscheidungsv erfahren entfernt. Die auf diese Weise erzeugte kolloide Lösung natürlicher Seide -wird nun bei verhältnismäßig niedriger Temperatur konzentriert. Um aus dieser konzentrierten Kolloidseidenlösung wieder Seidenfäden oder -fasern zu gewinnen, wird die Lösung in feinen Fäden durch Löcher einer Vorrichtung hindurchgezogen, die in derselben Weise ausgebildet ist wie bei der gewerblichen Herstellung künstlicher Seide. Diese Fäden werden dann durch ein Kristallisationsbad, z. B. Essigsäure, Methylalkohol oder andere bekannte Trocknungsmittel, hindurchgezogen. Es können auch dünne papierartige Blätter aus natürlicher Seide dadurch hergestellt werden, daß die konzentrierte Kolloidseidenlösung über eine ebene Fläche, z. B. eine Glasplatte, ausgebreitet und dann getrocknet wird. Die Seidenlösung kann auch als plastische Masse verwendet werden. Vor oder nach Entfernung des Salzes kann zur Erhöhung der Widerstandsfähigkeit und Geschmeidigkeit eine geeignete Menge Gelatine, Glykose o. dgl. hinzugefügt werden.As an embodiment of the invention, about ten parts Magnesium nitrate dissolved in five parts of water. This solution is brought to a temperature warmed by about iio ° C. Then two or three parts of silk waste gradually and after adding small amounts to the magnesium nitrate solution, which is stirred gently will. The silk waste (natural raw silk threads, old silk fabrics). The magnesium salt is then made from the colloidal Solution removed by dialysis or other common deposition method. The colloidal solution of natural silk produced in this way is now used in proportion concentrated at a low temperature. To get out of this concentrated colloidal silk solution To win back silk threads or fibers, the solution is made into fine threads Holes pulled through a device that is formed in the same way as with the commercial manufacture of artificial silk. These threads are then passed through a crystallization bath, e.g. B. acetic acid, methyl alcohol or other known desiccants, drawn therethrough. It can also be thin paper-like Sheets made from natural silk are made by having the concentrated Colloidal silk solution over a flat surface, e.g. B. a glass plate spread out and then dried. The silk solution can also be used as a plastic mass will. Before or after removal of the salt can increase the resistance and pliability, an appropriate amount of gelatin, glycose or the like can be added.
