  Procédé de fabri cation de fibres mates

  
La présente invention concerne un procédé de fabrication de fibres mates par le procédé Viscose. Le procédé suivant l'invention consiste à soumettre au filage une viscose qui renferme

une rugosité très prononcée. De ce fait le produit filé présente un aspect écailleux, ressemblant à la laine, et perd surtout le brillant caractéristique des filaments ou fils régénérés.

  
Une solution à filer de ce genre peut être obtenue suivant la présente invention de la manière la plus commode moyennant l'emploi d'un dispositif tel que représenté, à titre d'exemple, sur le dessin annexé. La quantité de viscose admise dans la machine à filer est réglée de manière que, pour une longueur de conduite de, par exemple, 10 à 15 mètres, la vitesse

  
de passage de la quantité de viscose à filer dans la machine soit

  Mat fiber manufacturing process

  
The present invention relates to a process for producing mat fibers by the viscose process. The process according to the invention consists in subjecting to the spinning a viscose which contains

  
 <EMI ID = 1.1>

  
in this case the droplets present in a state of division and

  
 <EMI ID = 2.1>

  
a very pronounced roughness. As a result, the spun product has a scaly appearance, resembling wool, and above all loses the characteristic shine of the filaments or regenerated threads.

  
Such a spinning solution can be obtained according to the present invention most conveniently by employing a device as shown, by way of example, in the accompanying drawing. The quantity of viscose admitted into the spinning machine is adjusted so that, for a pipe length of, for example, 10 to 15 meters, the speed

  
of the quantity of viscose to be spun through the machine is

  
 <EMI ID = 3.1>

  
ment, as appropriate shown in the drawing, the amount

  
 <EMI ID = 4.1>

  
 <EMI ID = 5.1>

  
this motor directly controls a mixing propeller The shaft enters the viscose pipe through a box

  
stuffing. To improve the mixing action, the propellers are constructed in such a way that their direction of propulsion is each time the opposite of that of the previous propeller. Upstream of the

  
 <EMI ID = 6.1>

  
a capillary tube waiting in the said pipe, through

  
 <EMI ID = 7.1>

  
of carbon exactly dosed.

  
An essential condition for obtaining a matt fiber according to the invention is that the excess carbon disulfide added to the viscose is still mechanically divided and distributed in the latter. On the other hand, when the reaction of carbon disulphide with the alkali -cellulose is allowed to terminate, of which when one waits until the carbon disulphide is chemically

  
 <EMI ID = 8.1>

  
 <EMI ID = 9.1>

  
where the viscose containing excess carbon disulphide is spun. fi
