  Verfahren zur Herstellung von Glühstrümpfen. 



   Es ist bekannt, bei der Herstellung von   Glühstrümpfen Gewebe,   die mit Thoriumnitrat und Cernitrat getränkt wurden, behufs Ausfällung der Hydroxyde mit Wasserstoffsuperoxyd zu behandeln, jedoch wird hiebei nur das Thorium quantitativ niedergeschlagen, nicht aber das Cer. Um die Fällung des Cers zu vervollständigen, ist vorgeschlagen worden, dem Wasserstoffsuperoxyd Ammoniak oder Natriumazetat zuzusetzen. 



   Gegenstand der Erfindung ist nun ein Verfahren, das die quantitative Ausfällung

Es wird dies dadurch erreicht, dass man auf die mit der Leuchtsalzmischung getränkten Fasern eine Hypochloritlösung einwirken lässt. Diese übt auf die Salze eine   oxydierende'und fällende Wirkung   aus, beeinflusst aber auch das   Strumpfmaterial   bzw. die Kunstseide der Strümpfe, indem

   Da das käufliche Thoriumnitrat mit einem Gehalt von   dz   Oxyd eine sauer   reagierende Verbindung von nicht   ganz konstanter Zusammensetzung darstellt und die Iteaktion der llypoelilorite auf die seltenen Erden sich nur   ill   Lösungen, die nahezu neutral sind, gut   vollzieht,   so erscheint es notwendig, das Bad der   Leuchtsalze   auf einen möglichst geringen Gehalt an freier Säure zu bringen. Zu diesem Zwecke werden die

  Process for manufacturing incandescent mantles.



   It is known to treat tissues soaked with thorium nitrate and cerium nitrate in the manufacture of incandescent mantles with hydrogen peroxide to precipitate the hydroxides, but only the thorium is quantitatively precipitated, but not the cerium. In order to complete the precipitation of the cerium, it has been proposed to add ammonia or sodium acetate to the hydrogen peroxide.



   The invention now relates to a process which involves quantitative precipitation

 the latter firmly adhere to the natural or artificial tissue fibers. This is achieved by allowing a hypochlorite solution to act on the fibers soaked with the luminous salt mixture. This has an oxidizing and precipitating effect on the salts, but also influences the stocking material or the rayon of the stockings by

 be liable. As a result, the mantles after incineration are more pliable and more durable than those made by conventional methods.



   Since the commercially available thorium nitrate with a content of dz oxide is an acidic compound of not entirely constant composition and the reaction of the llypoelilorite on the rare earths only works well in solutions that are almost neutral, it seems necessary to use the bath of the Bringing luminous salts to the lowest possible free acid content. For this purpose, the
