Description
<EMI ID=1.1>
<EMI ID=2.1>
approprié dans la pratique$ car le soufre amorphe du bisulfure
de carbone adhérant à la scie n'est pas dissous. Toutefois, l'emploi de solutions aqueuses pour la désulfuration de .produits artificiels de viscose par la voie mécanique, par exemple par
<EMI ID=3.1>
des difficultés techniques, car le gonflement considérable de <EMI ID=4.1>
la soie artificielle provoqué par la solutions'oppose à une pénétration uniforme de la soie artificielle par le liquide désulfurant.
La présente invention a pour objet un procédé qui permet
<EMI ID=5.1>
maint la désulfuration en grandes quantités des produits arti-
<EMI ID=6.1>
Le procédé .est basé sur l'emploi de solutions qui n'exercent aucune action de gonflement ou seulement une action très faible de gonflement sur la soie artificielle. On emploie, de
<EMI ID=7.1>
produits artificiels. On peut aussi ajouter une minime quantité
<EMI ID=8.1>
qui évitent un gonflement trop prononcé de la soie artificielle.
Dans son application à la désulfuration de la soie artificielle de viscose) le procédé est exécuté par exemple de la manière suivante:
La soie artificielle de viscose non désulfurée, sur bobiness ou en écheveaux ou sous toute autre forme, est chargée dans des . appareils clos et le désulfurant est envoyé par pompage à travers la soie artificielle*- ou bien la désulfuration de la soie est
<EMI ID=9.1>
tant les bobines, etc:, il. sur des bras perfores et en pompant les solutions à travers la soie. Après la désulfuration on débarrasse la soie des restes du liquide désulfurant par des solvants, de
<EMI ID=10.1>
Indépendamment de l'économie considérable de main d'oeuvre, le procédé présente l'avantage technique spécial que la soie sous forme d'éaheveau n'est pas emmêlée par le lavage au moyen de solutions organiques, de sorte que le traitement et le travail ultérieur de la soie artificielle dësulfurée se font dans de bien meilleures conditions; en outre, la qualité de la soie arti-
<EMI ID=11.1>
la souplesse, une différence eonsidérable entre la soie désulfu... rée avec des solutions aqueuses et la. soie désulfurée par voie organique d'après le présent procédé. L'élasticité: à l'état sec
<EMI ID=12.1>
avec des solutions aqueuses.
La soie désulfurée conformément à l'invention montre dans
le tissu brut un brillant remarquablement plus doux que la soie artificielle désulfurée par les méthodes en usage jusqu'à présent,
<EMI ID=13.1>
cas échéant, en modifiant d'une façon appropriée les appareils,
<EMI ID = 1.1>
<EMI ID = 2.1>
suitable in practice $ because the amorphous sulfur of the disulfide
of carbon adhering to the saw is not dissolved. However, the use of aqueous solutions for the desulphurization of artificial viscose products by mechanical means, for example by
<EMI ID = 3.1>
technical difficulties, because the considerable swelling of <EMI ID = 4.1>
The artificial silk caused by the solution opposes uniform penetration of the artificial silk by the desulfurizing liquid.
The present invention relates to a method which allows
<EMI ID = 5.1>
maintain the desulphurisation in large quantities of arti-
<EMI ID = 6.1>
The method is based on the use of solutions which exert no swelling action or only a very weak swelling action on the artificial silk. We use
<EMI ID = 7.1>
artificial products. You can also add a small amount
<EMI ID = 8.1>
which avoid too pronounced swelling of the artificial silk.
In its application to the desulphurization of artificial viscose silk), the process is carried out, for example, as follows:
Artificial silk of non-desulfurized viscose, on bobbin or in hanks or in any other form, is loaded into. closed apparatus and the desulfurizer is pumped through the artificial silk * - or the desulfurization of the silk is
<EMI ID = 9.1>
both the coils, etc :, there. on perforated arms and pumping the solutions through the tang. After desulfurization, the silk is freed from the remains of the desulfurizing liquid with solvents,
<EMI ID = 10.1>
Apart from the considerable saving in manpower, the process has the special technical advantage that the silk in the form of a skein is not tangled by washing by means of organic solutions, so that the processing and working subsequent desulphurized artificial silk are made under much better conditions; in addition, the quality of the arti-
<EMI ID = 11.1>
flexibility, a considerable difference between silk desulfurized ... with aqueous solutions and. organically desulfurized silk according to the present process. Elasticity: dry
<EMI ID = 12.1>
with aqueous solutions.
The desulfurized silk according to the invention shows in
the raw fabric has a remarkably softer sheen than artificial silk desulphurized by the methods in use until now,
<EMI ID = 13.1>
if necessary, by modifying the devices in an appropriate manner,
