Description

Verfahren zur Nachbehandlung künstlicher Fäden und anderer Zellulosegebilde aus Viskose oder anderen Zelluloseverbindungen. Die aus Viskose oder anderen Zelluloseverbindungen erhaltenen Zellulosegebilde bedürfen in vielen Fällen einer Nachbehandlung. Nach dem vorliegenden Verfahren erfolgt diese Nachbehandlung der gefällten Zellulosefäden, nachdem sie aus dem Fällbade gekommen sind, durch ein Bad aus (gegebenenfalls eingedickter und von Kalksalzen befreiter) Sulfitzellstoffablauge und Mineralsäuren, z. B. Schwefelsäure. Man kann auch Mischungen verschiedener Säuren benutzen. Man verwendet beispielsweise eine Mischung, welche im Liter enthält: ioo bis zoo g eingedickte Sulfitzellstoffablauge und 5o bis ioo g Schwefelsäure 66° B6. Die Sulfitablauge kann im eingedickten Zustande, nachdem sie vom überschüssigen Kalk befreit ist, verwendet werden. Die gefällten Zellulosefäden und andere Zellulosegebilde zeigen einen hohen Glanz und guten Griff und sind sehr beständig. Das Verfahren ist für alle gefällten Zellulosefäden verwendbar. Besonders ist es für Zellulosefäden geeignet, die mit einem Fällbade aus Sulfitzellstoffablauge und Ammoniumsalzen hergestellt sind.Process for the aftertreatment of artificial threads and other cellulose structures made of viscose or other cellulose compounds. Those made from viscose or other cellulose compounds Cellulose structures obtained require post-treatment in many cases. To In the present process, this post-treatment of the precipitated cellulose threads takes place, after they have come out of the felling bath, through a bath (possibly thickened and from lime salts) sulphite pulp waste liquor and mineral acids, e.g. B. sulfuric acid. Mixtures of different acids can also be used. One uses, for example a mixture which per liter contains: 100 to 100 g concentrated sulphite pulp waste liquor and 50 to 100 g of sulfuric acid 66 ° B6. The sulphite waste liquor can in the thickened state, after it has been freed from excess lime, can be used. The fallen ones Cellulose threads and other cellulose structures show a high gloss and a good handle and are very consistent. The process can be used for all precipitated cellulose threads. It is particularly suitable for cellulose threads with a felling bath made from sulphite pulp waste liquor and ammonium salts are produced.

Das Nachbehandlungsbad wirkt im Gegensatz zu dem bisher üblichen weit milder und ruhiger; seine kolloidale Beschaffenheit bewirkt die Gewinnung eines glänzenden, gleichmäßigen, nicht blasigen Fadens, der wesentlich schwieriger aufgeweicht und gelöst wird.The aftertreatment bath has a wide effect in contrast to the previously usual one milder and calmer; its colloidal nature causes a shiny, even, non-blistered thread, which is much more difficult to soften and is resolved.
