Description

  

      Verfahren    zur Herstellung von Kunstseide, Bändchen usw.    Es wurde gefunden, dass man     künstliche          Gebilde    wie Kunstseide, Bändchen     usw.    aus       Zelluloselösungen    erhalten kann,     wenn    man  beispielsweise den aus dem Spinnbad austre  tenden Faden zwischen dem Spinnbad und  dem Aufnahmeorgan (Spule, Haspel, Zentri  fuge usw.) unter zusätzlicher Streckung des  Fadens durch ein Wasserbad beliebiger Tem  peratur leitet.  



  Durch diese Nachbehandlung des gespon  nenen     Kunstseidefadens    während des Spinn  prozesses werden Nass- und     Trockenfestig-          keiten    erhalten, die weit über den sonst nor  malen     Werten    liegen. Das Verfahren wird  an Hand des folgenden Beispiels näher er  läutert.  



       Eine    normale Viskose mit einem     Zelln-          losegehalt    von<B>7,5%</B> und einem     Alkaligehalt     von<B>6,5%</B> wird bei einer durch     durchschnitt-          lichen    Reife von 10,6 nach     Hottenroth    bei  einem     Deniers    von 120, einer Düse mit 60  Loch und einem Abzug von 70 m in der     1VIi-          nute    in ein normales Spinnbad für Viskose  seide, beispielsweise mit einem Gehalt von  150 g Schwefelsäure im Liter und einem Ge  halt von Natriumsulfat, dass die Dichte bei  20   1,260 beträgt, versponnen.

   Nach Ver  lassen des Spinnbades wird der Faden zwi-    sehen     Spinnbad    und dem Aufnahmeorgan  durch ein Wasserbad mit einer     Temperatur     von 45   C geleitet, wobei der Faden mit  Hilfe bekannter Vorrichtungen, wie zwischen  zwei mit verschiedener Geschwindigkeit um  laufenden Walzen, durch Überleiten über  kammartig angeordnete Glasstäbe usw.     ge-          streckt    wird.

   Die nach diesem Beispiel her  gestellte Kunstseide hat einen Festigkeits  wert, der sowohl nass wie trocken wesentlich  höher liegt, als derjenige von Vergleichs  seiden, die sonst unter den gleichen Bedin  gungen hergestellt sind, jedoch ohne den Fa  den nach Verlassen des Spinnbades unter       Streckung    durch ein Wasserbad von beliebi  ger Temperatur zu leiten.



      Process for the production of rayon, ribbon etc. It has been found that artificial structures such as rayon, ribbon etc. can be obtained from cellulose solutions if, for example, the thread exiting from the spinning bath is placed between the spinning bath and the receiving organ (bobbin, reel, centri joint, etc.) with additional stretching of the thread through a water bath of any temperature.



  As a result of this post-treatment of the spun rayon thread during the spinning process, wet and dry strengths are obtained that are well above the otherwise normal values. The procedure is explained in more detail using the following example.



       A normal viscose with a cellulose content of <B> 7.5% </B> and an alkali content of <B> 6.5% </B> with an average ripeness of 10.6 according to Hottenroth a denier of 120, a nozzle with 60 holes and a draw of 70 m in the 1VI- minute in a normal spinning bath for viscose silk, for example with a content of 150 g sulfuric acid per liter and a Ge content of sodium sulfate, that the density at 20 is 1.260, spun.

   After leaving the spinning bath, the thread is passed between the spinning bath and the receiving organ through a water bath at a temperature of 45 C, the thread being passed over comb-like arranged glass rods with the aid of known devices, such as between two rollers rotating at different speeds etc. is stretched.

   The artificial silk produced according to this example has a strength value that is both wet and dry much higher than that of comparison silk, which are otherwise produced under the same conditions, but without the thread after leaving the spinning bath with stretching To conduct a water bath of any temperature.
