Verfahren zur Herstellung von WoüersaMäsera aus Viskose.
Es ist bekannt, aus Viskose wasser-oder alkalilösliche Xanthogenatfäden herzustellen und den Xanthogenatfaden erst in einem zweiten Bad zu Cellulose zu zersetzen. Die Zersetzung des wasserlöslichen Fadens mittels Mineralsäuren wird hiebei entweder am laufenden Faden oder auf dem Aufwickelorgan vorgenommen. Zur Herstellung von Stapelfasern ist schon vorgeschlagen worden, die aus Viskose gesponnenen Xanthogenatfäden vom Aufwickelorgan abzuschneiden und die Fadenmasse durch Einlegen in ein Säurebad zu Cellulosefasern zu zersetzen.
Bei dem Verfahren der vorliegenden Erfindung sollen die in bekannter Weise in Ammoniumsulfatlösungen, organischen Säurelösungen oder sehr verdünnten Mineralsäuren gesponnenen Xanthogenatfäden einer grossen Anzahl von Spinndüsen zu einem starken Faserband von mehreren 1000 Deniers zusammengefasst und einer Schneidemaschine zugeführt werden. Die in Stapel geschnittenen starken Bänder werden hierauf einem Schwemmprozess in verdünnten Mineralsäuren unterworfen, wodurch

Um eine gute Verteilung der geschnittenen Stapellängen in Einzelfasern zu bewirken, wird beispielsweise die im Zersetzungsbad verteilte Fadenmasse durch einen oder mehrere Türme e, e, geleitet, in welche Prallflächen i zum Aufschlagen der Faserbiindel eingebaut sind. Am unteren Ende jedes Turmes wird die Fadenmasse auf ein umlaufendes, endloses Fördersieb g aufgebracht und dadurch von der Zersetzungsflüssigkeit abgetrennt. Das Fördersieb

Am Ende der verschiedenen Fördersiebe wird die Fasermasse zweckmässig zwischen Quetschwalzen A durchgeführt, um die aufgesaugte Flüssigkeit abzupressen. Schliesslich passiert das Faservlies auf Förderbändern einen

kann auf den Fördersieben eine zusätzliche Berieselung mit Behandlungsflüssigkeiten durchgeführt werden.
Die Behandlungsflüssigkeiten werden in Trögen & unter den Fördersieben aufgefangen, in Bottichen l auf die ursprüngliche Konzentration eingestellt und mit Pumpen m den Behandlungstellen wieder zugeführt.
Das Produkt des beschriebenen Verfahrens ist eine Stapelfaser in Vliesform von guter, woll- ähnlicher Kräuselung, welche sich zum Verspinnen besonders gut eignet.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Wollersatzfasern aus Viskose, dadurch gekennzeichnet, dass endlose, starke Faserbänder aus Xanthogenatfäden in Stapel geschnitten werden, die Abschnitte des Xanthogenatfadens unter Zersetzung zu Cellulosehydrat in sauren Badflüssigkeiten mechanisch aufgeschlagen oder durch Strömungsvorgänge geöffnet und anschliessend den einzelnen Nachbehandlungsbädern in ununterbrochenem Arbeitsgang zugeführt werden.

Process for the production of WoüersaMäsera from viscose.
It is known to produce water- or alkali-soluble xanthate threads from viscose and only decompose the xanthate threads into cellulose in a second bath. The decomposition of the water-soluble thread by means of mineral acids is carried out either on the running thread or on the winding element. For the production of staple fibers, it has already been proposed to cut off the xanthate threads spun from viscose from the winding element and to decompose the thread mass into cellulose fibers by placing it in an acid bath.
In the process of the present invention, the xanthate threads of a large number of spinnerets, spun in a known manner in ammonium sulfate solutions, organic acid solutions or very dilute mineral acids, are to be combined into a strong fiber sliver of several 1000 deniers and fed to a cutting machine. The strong strips cut into stacks are then subjected to a flushing process in dilute mineral acids, whereby

EMI2.1
Sulfuric acid still contains 120po sodium sulfate.
In order to achieve a good distribution of the cut staple lengths in individual fibers, the thread mass distributed in the decomposition bath, for example, is passed through one or more towers e, e, in which baffles i are installed for breaking the fiber bundle. At the lower end of each tower, the thread mass is applied to a revolving, endless conveyor sieve g and thereby separated from the decomposition liquid. The conveyor sieve

Distribution to a further tower e2 with built-in baffles, in which the fibers are freed from the adhering decomposition bath by washing with water. The fiber fleece is fed in the same way to all treatment baths required for finishing.
At the end of the various conveyor sieves, the fiber mass is expediently passed between nip rollers A in order to squeeze out the sucked up liquid. Finally, the fiber fleece passes one on conveyor belts
EMI2.3
an additional sprinkling of treatment liquids can be carried out on the conveyor sieves.
The treatment liquids are collected in troughs & under the conveyor sieves, adjusted to the original concentration in vats 1 and fed back to the treatment points with pumps.
The product of the process described is a staple fiber in fleece form with good, wool-like crimp, which is particularly well suited for spinning.
PATENT CLAIMS:
1. A process for the production of wool substitute fibers from viscose, characterized in that endless, strong fiber ribbons of xanthate threads are cut into stacks, the sections of the xanthate thread are mechanically whipped with decomposition to cellulose hydrate in acidic bath liquids or opened by flow processes and then the individual aftertreatment baths in an uninterrupted operation are fed.
