Description

Verfahren zur Herstellung von spinnbaren Lösungen von Seidenfibroin Die im Patent 510 489 beschriebenen sauren Lösungen von Seidenfibroin lassen sich aus Einzeldüsen ohne Schwierigkeiten zu feinen Fäden ausziehen. Beim Spinnen durch die in der Kunstseidentechnik üblichen Düsen mit vielen Löchern zeigt jedoch das Faserbündel eine unerwünschte Neigung zum Verkleben der einzelnen Kapillarfäden, auch wenn das Fällbad sehr lang gewählt wird. Nach vorliegender Erfindung kann dieses Zusammenkleben auf ein so geringes Maß eingeschränkt werden, daß eine Nachbehandlung mit Netzmitteln, Seifen u. dgl. die einzelnen Kapillarfäden vollkommen freilegt. Dieser Effekt wird erreicht durch einen Zusatz von ätherischen Ölen, z. B. Terpentinöl, zu der sauren Spinnlösung. Es genügen schon sehr geringe Mengen, z. B. 0,02 bis o,i °/a Ölzusatz, auf die Spinnlösung berechnet. Eine schwache Braunfärbung der Spinnlösung ist bedeutungslos und hat keinen Einfluß auf die Farbe des fertigen Fadens. Durch den Zusatz von ätherischem Öl wird zugleich die Loslösung der einzelnen Fasern von der Düse erleichtert und damit die Spinnsicherheit und die Gleichmäßigkeit des Titers erhöht.Process for the production of spinnable solutions of silk fibroin The acidic solutions of silk fibroin described in the patent 510 489 can be drawn into fine threads from individual nozzles without difficulty. When spinning through the nozzles with many holes that are common in artificial silk technology, however, the fiber bundle shows an undesirable tendency to stick the individual capillary threads together, even if the precipitation bath is chosen to be very long. According to the present invention, this sticking together can be restricted to such a small extent that an aftertreatment with wetting agents, soaps and the like completely exposes the individual capillary threads. This effect is achieved by adding essential oils, e.g. B. turpentine oil, to the acidic spinning solution. Very small amounts are sufficient, e.g. B. 0.02 to o, i ° / a oil addition, calculated on the spinning solution. A weak brown coloration of the spinning solution is meaningless and has no influence on the color of the finished thread. The addition of essential oil also facilitates the detachment of the individual fibers from the nozzle and thus increases the spinning reliability and the uniformity of the titer.
