  Verfahren zum Veredeln von künstlicher Seide. 



   Nach einem früheren Verfahren des Erfinders werden der Kunstseide vorteilhafte Eigenschaften durch Behandlung mit heissen basischen Substanzen, insbesondere Alkalilaugen und Alkalisulfidlösungen verliehen, u. zw. im Gegensatz zur Behandlung bei Zimmertemperatur, die eine derart günstige Ver- änderung der Kunstseide herbeizuführen nicht vermag. Es konnte festgestellt werden, dass Alkalilaugen über 30% eine Ausnahme bilden, indem die Wirkungen solcher Laugen in der Kälte und Wärme keinen wesentlichen Unterschied aufweisen. Wenn man z. B. 36 oder 40 oder   50% ige   Natronlauge auf Kunstseide in Form von Fäden oder Geweben einmal bei 15 und einmal bei 100  C oder darüber, z.

   B.   140    C, einwirken lässt, dann kann man feststellen, dass der Glanz und der Griff nicht wesentlich leiden, dass die   Trocken-und Nassfestigkeit   ungefähr auf der ursprünglichen Höhe bleibt und die Dehnbarkeit in die Höhe geht. 



   Dem Verfahren kann Kunstseide im gespannten oder ungespannten Zustande unterworfen werden. 



  Die Einwirkungsdauer der starken Lauge bei Zimmertemperatur kann eine Minute oder auch länger betragen. Die Nachbehandlung kann entweder durch sofortiges Waschen mit heissem und dann kaltem Wasser oder durch Einbringen der Kunstseide in ein Säurebad, z. B. in   10-20%ige Schwefelsäure,   erfolgen. 



   Unter "Kunstseide" wird verstanden : Kunstfäden als solche (z. B. Kunstseide, Stapelfaser, Kunstwolle, Kunsthaar, Kunststroh) in Gestalt von Gespinsten (Fäden, Garne in Strähnen oder Kopsen oder   in Form von Ketten oder gezwirntem Garn od. dgl. ) und Kunstfäden (z. B. Kunstseide oder Stapelfaser)   in Form von Geweben.

  Process for finishing artificial silk.



   According to an earlier method of the inventor, the rayon is given advantageous properties by treatment with hot basic substances, in particular alkali lyes and alkali sulfide solutions, and the like. in contrast to treatment at room temperature, which is unable to bring about such a favorable change in the rayon. It was found that alkali solutions over 30% are an exception, as the effects of such bases in cold and warm conditions do not show any significant difference. If you z. B. 36 or 40 or 50% sodium hydroxide solution on rayon in the form of threads or fabrics once at 15 and once at 100 C or above, z.

   B. 140 C, then you can see that the gloss and the feel do not suffer significantly, that the dry and wet strength remains approximately at the original level and the elasticity increases.



   Rayon can be subjected to the process in a stretched or untensioned state.



  The exposure time to the strong lye at room temperature can be one minute or longer. The aftertreatment can be carried out either by washing immediately with hot and then cold water or by placing the rayon in an acid bath, e.g. B. in 10-20% sulfuric acid.



   "Artificial silk" is understood to mean: artificial threads as such (e.g. artificial silk, staple fibers, artificial wool, artificial hair, artificial straw) in the form of spun threads (threads, threads in strands or cops or in the form of chains or twisted thread or the like) and synthetic threads (e.g. rayon or staple fiber) in the form of woven fabrics.
