Description
Procédé de fabrication de soie artificielle.
<EMI ID=1.1>
a décrit un procédé de filage de solutions cellulosiques ammo-
<EMI ID=2.1>
En poussant pius loin les perfectionnements de ce procédé, on a découvert qu' en opérant à des températures inférieures on peut considérablement améliorer de façon extrêmement simple en leurs propriétés aussi bien les solutions cellulosiques ammoniacales d'oxyde de cuivre provenant de cellulose de bois, de paille et de matières semblables, que celles provenant de filasses de coton, si l'on a soin d'obtenir un agrandissement
<EMI ID=3.1>
surprenant et caractéristique que l'on puisse filer ainsi les solutions cellulosiques ammoniacales provenant dé filasse de coton que l'on ne pouvait pas filer jusqu'à présent à des températures si basses. Comme longueur de précipitation, on prend alors par exemple de 50 à 80 cm. Le progrès important résultant de ce nouveau procédé de filage est de rendre bien meil-

tat humide. Suivant ce nouveau procédé, on rehausse par exemple de 100 % la résistance du 'fil à l'état sec ou humide.
De plus, ce mode opératoire spécial contribue efficacement
<EMI ID=5.1>
qui- joue un rôle capital et très frappant dans des procédés de filage de ce genre* Ce traitement qui contribue à bien ménager le fil au cours de la phase de filage proprement dit implique manifestement l'amélioration éminente de la qualité du fil dont il a été fait mention plus haut.
Manufacturing process of artificial silk.
<EMI ID = 1.1>
described a process for spinning ammo cellulose solutions
<EMI ID = 2.1>
By pushing further the improvements of this process, it has been discovered that by operating at lower temperatures one can considerably improve in an extremely simple way in their properties both the ammoniacal cellulosic solutions of copper oxide originating from wood cellulose, straw and the like, as from cotton yarns, if care is taken to obtain an enlargement
<EMI ID = 3.1>
surprising and characteristic that it is possible to spin in this way the ammoniacal cellulosic solutions obtained from cotton wool which could not hitherto be spun at such low temperatures. The precipitation length is then for example 50 to 80 cm. The important progress resulting from this new spinning process is to make much better

wet condition. According to this new process, for example, the resistance of the yarn in the dry or wet state is increased by 100%.
In addition, this special operating mode effectively contributes
<EMI ID = 5.1>
which plays a capital and very striking role in spinning processes of this type mentioned above.
