Description

  

  Verfahren zur Herstellung feiner glänzender Fäden.    Nach Angaben der Literatur soll zur  Herstellung feinster Fäden aus Viskose  ,     lösungen    der Grad .der Feinheit. :der Fäden  abhängig sein vom Prozentgehalt des Fäll  bades an Schwefelsäure, so dass zum Beispiel  die Mindestkonzentration für     Kunstseide    von       -3        Deniers    250 bis 280     gr    Schwefelsäure  Monohydrat im Liter und für Kunstseide  von 4     Deniers    170 bis 190     gr    im Liter be  trägt. Diesen Bädern sollen 360     :gr    Glauber  salz zugesetzt werden.

   Im Gegensatz zu ;die  sen Angaben wurde festgestellt, dass die Ein  haltung der obigen Mindestkonzentrationen  nicht notwendig ist, um die genannten     Fäd-          eben    verschiedenen     Titers    zu spinnen. Es  wurde in der Tat gefunden,     dass    man     glän-          zen:de    Fäden von 2,5 bis 6     Deniers    aus     Vis-          koselösungen    herstellen kann, wenn man       Fällbäder    mit einem Gehalt an Schwefelsäure  von J.7.0 bis 160     gr    im Liter und einem so  hohen Gehalt an Salz. z.

   B.     Glaubersalz,     v     crwendet,        da.ss    das spezifische Gewicht der  Bäder     1,,3\2    bis 1,42     beträgt.     



       Beispiel:     Man verspinnt Viskose mit einer Reife  von 8 bis<B>10'</B> Chlorammonium in einem Bade    mit 160     gr    Schwefelsäure pro Liter, dem so  viel Glaubersalz zugefügt     wird,    dass das spe  zifische Gewicht 1,32 bis 1,42 beträgt. Die       Tauchstrecke    wählt     man    am besten zwischen  10 bis 15 cm und die Temperatur zwischen       4'1    bis 50  .     Empfehlensw        ert    ist es, ein Ober  bad zu verwenden, das 5      io    Schwefelsäure  enthält und aus     verdünntem        Fällbad    besteht.  



  Gegenüber dem     bekannten    Verfahren hat  das vorliegende den     Vorteil,    dass für ver  schiedene     Titer    immer ein einheitliches Bad  verwendet und nur die Stoffzufuhr geändert  zu werden braucht.



  Process for the production of fine shiny threads. According to the literature, the degree of fineness should be used to manufacture the finest threads from viscose. : the threads depend on the percentage of sulfuric acid in the precipitation bath, so that, for example, the minimum concentration for rayon of -3 deniers is 250 to 280 grams of sulfuric acid monohydrate per liter and for rayon of 4 deniers 170 to 190 grams per liter. 360: g Glauber salt should be added to these baths.

   In contrast to these data, it was found that compliance with the above minimum concentrations is not necessary in order to spin the named threads of different titers. It has indeed been found that shining threads of 2.5 to 6 deniers can be made from viscose solutions if one uses precipitation baths with a sulfuric acid content of 7.0 to 160 grams per liter and such a high one Salt content. z.

   B. Glauber's salt, v crwendet that the specific gravity of the baths 1,, 3 \ 2 to 1.42.



       Example: Viscose with a maturity of 8 to <B> 10 '</B> chlorammonium is spun in a bath with 160 grams of sulfuric acid per liter, to which so much Glauber's salt is added that the specific weight is 1.32 to 1.42 amounts. The diving distance is best chosen between 10 to 15 cm and the temperature between 4'1 to 50. It is recommended to use an upper bath that contains 5 io sulfuric acid and consists of a diluted precipitation bath.



  Compared to the known method, the present one has the advantage that a uniform bath is always used for different titers and only the substance supply needs to be changed.
