Description
Verfahren zur Herstellung einer Faser mit erhöhtem Spinn-, Filz- und Walkvermögen und erhöhter Wärmehaltung aus Cellulosefaser. Die künstlichen Fasern, die bisher als Beimischung zur Wolle oder an Stelle der Wolle Verwendung finden, haben noch den Nachteil an sich, dass die Spinn-, Filz- und Walkfähigkeit geringer ist als bei der natür lichen Wolle, und dass sie auch in ihrer Wärmehaltung nicht an die natürliche Wolle herankommen.
Die vorliegende Erfindung betrifft nun ein Verfahren zur Herstellung einer Faser, die in ihrer Spinn-, Filz- und Walkfähigkeit sowie in ihrer Wärmehaltung der Wolle nahekommt, und das es gestattet, diese Ei genschaften, die auch bei den einzelnen Woll- sorten nicht im gleichen Massstabe vorhanden sind, weitgehend zu variieren und dem be sonderen Verwendungszweck anzupassen.
Das Verfahren ist dadurch gekennzeich net, dass die Zellulosefaser in noch unfertigem und ungetrocknetem Zustand sofort nach dem Spinnprozess und daran anschliessendem Aus waschen durch ein Bad geführt wird, das gleichzeitig gelöste filmbildende Stoffe und zur Gasentwicklung befähigte Stoffe enthält, worauf in einem weiteren Bad, einem Zer setzungsbad, die Abscheidung des filmbil denden Stoffes auf der Faser bei gleichzei tiger Gasentwicklung bewirkt wird.
Durch die Gasentwicklung wird die Bildung eines zusammenhängenden Filmes entweder ganz verhindert, dadurch, dass die Gasblasen den Film sprengen und einzelne Schuppen bil den, oder der Film wird durch eingeschlos sene Gasblasen zwischen ursprünglichem Fa den und Filmhaut aufgebaucht.
Das Verfahren kann zum Beispiel so aus geführt werden, dass eine frisch gesponnene, in noch unfertigem Zustand befindliche Faser ausgewaschen wird und dann in einem Bad, welches

<tb> 1 <SEP> bis <SEP> 10 <SEP> g/Liter <SEP> Zellulose <SEP> in <SEP> Form <SEP> von
<tb> 1 <SEP> bis <SEP> 30 <SEP> g/Liter <SEP> Na2C03 <SEP> [Viskose enthält, getränkt wird. In einem darauf- folgenden Bad, das zum Beispiel aus einer verdünnten Säure oder auch aus einem der aus der Viskoseindustrie her bekannten Spinn bäder besteht, tritt bei erhöhter Temperatur von 40 bis 90 die Abscheidung der Zellu lose auf der Faser unter Gasentwicklung ein.
Der besondere Vorteil des beschriebenen Verfahrens besteht also darin, dass aus einer noch unfertigen Faser, die auf die normale einfache Art und Weise herzustellen ist, eine Faser hergestellt werden kann, die infolge der schuppenartigen Ansätze auf der Ober fläche, bezw. des Luftgehaltes zwischen Faser und Film eine hohe Spinn-, Filz- und Walkfähigkeit und gute Wärmehaltung be sitzt. Ein weiterer Vorteil bestellt darin, dass die Grösse und Zahl der Schuppen, bezw. der Gaseinschlüsse in weiten Grenzen variiert werden kann, so dass Fasern hergestellt wer den können, die ganz besondere Vorteile bei verschiedener Verwendungsfähigkeit besitzen, wozu bei der Verwendung von Naturwolle jeweils ganz besondere Wollsorten mit be sonderen Kräuselungs- oder Schuppencharak ter herangezogen werden.
Wesentlich für das neue Verfahren ist somit, dass nach demselben die Fasern durch die Behandlung mit Lösungen von filmbil denden Stoffen, zum Beispiel Zellulose, und gasentwickelnden Stoffen einen ganz andern Charakter als das Ausgangsmaterial an nehmen. Diese Veränderung des Charakters des Ausgangsmaterials nach der neuen Er findung liegt nun darin begründet, dass die Behandlung der Faser mit der Lösung der filmbildenden Stoffe, zum Beispiel der schup penbildenden Zelluloselösung, noch in einem Zustand v orgenomnmen wird, in dem die Faser selbst noch nicht vollständig fertig ist, in dem die Oberfläche und besonders das Innere des Fadens sieh noch in einem Übergangszu stand befindet,
zum Beispiel bei Verwendung von Viskose im Übergangszustand vom Zellu- lose-Xanthogenat zur Zellulose. Verwendet. man dabei Viskose als filmbildenden Stoff, so reagiert diese aufgebrachte Viskose viel leichter mit der Fasergrundlage, und es bil det sich eine viel engere Verbindung zwi- sehen Faser und filmbildendem Stoff. Erst nach demn Aufbringen des letzteren kann eine gemeinsame Nachbehandlung von Faser und Belag in der Entschwefelung, Bleichung, Avivage, und vor allen Dingen in der Trock nung stattfinden. Wichtig ist also, dass das Verfahren mit der unfertigen, ungetrockneten Faser ausgeübt wird, bei der noch keine Ver festigung und besonders Verhornung der Oberfläche stattgefunden hat.
Ebenso ist es von grosser Bedeutung, dass das neue Verfahren mit Viskoselösung jeder Stärke ausgeübt werden kann, also vor allen Dingen auch mit Viskosen unter 5 bis 7 % Zellulosegehalt. Die Möglichkeit der Ver wendung von Viskosen mit verschiedenem Zellulosegehalt bringt gerade den weiteren Vorteil mit sich, dass man den Charakter der Faser je nach demn Zellulosegehalt der Vis kose durch verschiedenen Grad der Belag bildung im weitesten Umfang ändern kann.
Der Behandlung kann die Zellulosefaser in Flocken- und in Strangform unterworfen werden.
Process for producing a fiber with increased spinning, felting and flexing power and increased heat retention from cellulose fiber. The artificial fibers, which have been used as an admixture to wool or instead of wool, still have the disadvantage that their spinning, felting and flexing properties are less than that of natural wool, and that they also retain heat cannot reach the natural wool.
The present invention relates to a process for the production of a fiber which comes close to wool in its spinning, felting and fulling ability and in its heat retention properties, and which makes it possible to use these properties that are not the same for the individual wool types Scales are available, to vary widely and to adapt to the special purpose.
The method is characterized in that the cellulose fiber in the still unfinished and undried state is passed through a bath immediately after the spinning process and subsequent washing, which simultaneously contains dissolved film-forming substances and substances capable of gas development, whereupon another bath, a Decomposition bath, the deposition of the filmbil Denden substance on the fiber with simultaneous gas evolution is effected.
The development of gas either completely prevents the formation of a coherent film, in that the gas bubbles burst the film and individual flakes form, or the film is bulged by gas bubbles enclosed between the original thread and the film skin.
The process can be carried out, for example, in such a way that a freshly spun, still unfinished fiber is washed out and then in a bath which

1 <SEP> to <SEP> 50 <SEP> g / liter <SEP> Na0H
<tb> 1 <SEP> to <SEP> 10 <SEP> g / liter <SEP> cellulose <SEP> in <SEP> form <SEP> of
<tb> 1 <SEP> to <SEP> 30 <SEP> g / liter <SEP> Na2C03 <SEP> [contains viscose, is soaked. In a subsequent bath, which consists, for example, of a dilute acid or of one of the spinning baths known from the viscose industry, the cells are deposited on the fiber at an elevated temperature of 40 to 90, with evolution of gas.
The particular advantage of the method described is that a fiber can be made from a still unfinished fiber, which can be produced in the normal simple manner, which, respectively, due to the scale-like approaches on the upper surface. the air content between fiber and film has a high spinning, felting and flexing ability and good heat retention. Another advantage is that the size and number of the scales, respectively. the gas inclusions can be varied within wide limits, so that fibers can be produced that have very special advantages for different uses, including when using natural wool, very special types of wool with special crinkling or flaky characters are used.
It is therefore essential for the new process that after the same treatment with solutions of film-forming substances, for example cellulose, and gas-evolving substances, the fibers take on a completely different character than the starting material. This change in the character of the starting material according to the new invention is due to the fact that the treatment of the fiber with the solution of the film-forming substances, for example the flake-forming cellulose solution, is still carried out in a state in which the fiber itself is not yet is completely finished, in which the surface and especially the inside of the thread is still in a transition state,
for example when using viscose in the transition state from cellulose xanthate to cellulose. Uses. If viscose is used as a film-forming substance, then this applied viscose reacts much more easily with the fiber base, and a much closer bond is formed between the fiber and the film-forming substance. Only after the latter has been applied can a joint post-treatment of the fiber and covering in desulphurisation, bleaching, softening and, above all, drying take place. It is therefore important that the process is carried out with the unfinished, undried fiber in which there has not yet been any solidification and, in particular, cornification of the surface.
It is also of great importance that the new process can be carried out with viscose solution of any strength, i.e. above all with viscose with a cellulose content of less than 5 to 7%. The possibility of using viscose with different cellulose content brings with it the further advantage that the character of the fiber can be changed to the greatest extent by different degrees of deposit formation, depending on the cellulose content of the viscose.
The cellulose fiber in flake or strand form can be subjected to the treatment.
