Description

  

  Verfahren zur Herstellung     künstlicher    Gebilde von mattem Aussehen aus Viskose.    Es ist vielfach vorgeschlagen worden,  einer Viskose Fremdkörper flüssiger oder  ,fester     Natur    einzuverleiben, um durch Ver  spinnen derartiger     Viskoseemulsionen    zu  künstlichen Fäden von     matt3m    Glanze zu ge  langen.  



  Derartige Emulsionen herzustellen, berei  tet keine wesentlichen     Schwierigkeiten.    Da  gegen ist es schwierig, homogene Mischungen  von harzartigen oder klebrigen Massen     rait     Viskose herzustellen. Unter diesen Verbin  dungen spielt der     Faktis    eine grosse Rolle,  doch gelang es bisher nicht, denselben mit  Viskose zu brauchbaren Emulsionen zu ver  mischen, da seine Klebkraft derartig gross ist,  dass eine feine     Verteilung,    wie sie für die  Emulsionen erforderlich ist, nicht herbei  geführt werden kann.  



  Es wurde nun gefunden, dass es trotz  dem gelingt zu Emulsionen von     Faktis    mit  Viskose zu kommen, und so     künstliche    Ge  bilde, wie Faden, Folien usw. von mattem    Aussehen zu erzeugen, wenn man diesen der  Viskose     in    gelöster Form beimischt. Vor  zugsweise verwendet man einen     Faktis,    wel  cher aus seinen Komponenten in Gegenwart  eines Lösungsmittels hergestellt wurde und       emulgiert    dieses flüssige     Reaktionsgemisch     mit der Viskose.

   Verwendet man dabei ein  flüchtiges Lösungsmittel, wie zum Beispiel  Benzin, so kann man das Benzin aus der       Viskoseemulsion        abdunsten    lassen,     ohne    dass  die Emulsion leidet und sie in ihrer Verwend  barkeit zur Herstellung von Fäden und an  dern     Gebilden    beeinträchtigt. Beim Verspin  nen derartiger Emulsionen erhält man Fäden  mit mattem Glanz.  



  Beispielsweise kann man folgendermassen  verfahren:  <B>150</B>     gr        Erdnussöl    werden in 1 1     #,    Liter  Benzin gelöst und mit 30 cm'     Schw2fel-          chlorür    vermischt. Man lässt das Gemisch bei  Zimmertemperatur so lange     stehen,    bis sich  der     Faktis    gebildet hat; derselbe bleibt in      Benzin gelöst. Die frei gewordene Salzsäure  wird durch Absaugen möglichst entfernt, wo  bei man das teilweise mit     abdunstende    Benzin  entsprechend ergänzt.  



  Das Gemisch wird dann mit 30 Liter Vis  kose     emulgiert    und die Emulsion in normaler  Weise in den bekannten Spinnbädern ver  sponnen, nachdem man vorher beim Entlüften  der Viskose dem Benzin Gelegenheit zum  Verdunsten gegeben hat.  



  Erforderlich ist es nicht, das Lösungsmit  tel restlos zu entfernen; es ist sogar möglich  das Lösungsmittel in der Viskose zu belassen.  Man kann der Viskose auch neben     Faktis       noch Zusätze an bekannten Matteffektmitteln  machen.  



  Selbstverständlich können die Verhält  nisse, in welchen     Faktis    mit Viskose gemischt  wird, in weiten Grenzen     schwanken,    je nach  dem Effekt, den man zu erzielen wünscht.



  Process for the production of artificial structures with a matt appearance from viscose. It has been suggested many times to incorporate foreign bodies of a liquid or solid nature into a viscose in order to ge long by spinning such viscose emulsions into artificial threads with a dull shine.



  To produce such emulsions, there are no significant difficulties. In contrast, it is difficult to produce homogeneous mixtures of resinous or sticky masses with viscose. Among these connec tions, the factice plays a major role, but it has not yet been possible to mix the same with viscose to form usable emulsions, since its adhesive strength is so great that a fine distribution, as is required for the emulsions, is not achieved can be.



  It has now been found that, in spite of this, it is possible to come up with emulsions of factice with viscose, and to produce such artificial Ge as threads, foils, etc. with a matt appearance when these are mixed with the viscose in dissolved form. Preferably, a factice is used which has been prepared from its components in the presence of a solvent and this liquid reaction mixture is emulsified with the viscose.

   If a volatile solvent, such as gasoline, is used, the gasoline can evaporate from the viscose emulsion without the emulsion suffering and impairing its availability for the production of threads and other structures. When spinning such emulsions, threads with a matt sheen are obtained.



  For example, you can proceed as follows: <B> 150 </B> g of peanut oil are dissolved in 11 liters of petrol and mixed with 30 cm of sulfuric acid. The mixture is left to stand at room temperature until the factice has formed; it remains dissolved in gasoline. The hydrochloric acid that has been released is removed as far as possible by suction, where the gasoline that is partially evaporating is supplemented accordingly.



  The mixture is then emulsified with 30 liters of viscose and the emulsion is spun in the normal manner in the known spinning baths after the gasoline has previously been given the opportunity to evaporate when venting the viscose.



  It is not necessary to completely remove the solvent; it is even possible to leave the solvent in the viscose. In addition to factice, you can also add well-known matt effect agents to the viscose.



  Of course, the proportions in which factice is mixed with viscose can vary within wide limits, depending on the effect that one wishes to achieve.
