Spinnbad unlöslich ist. Nach der ersten Berührung mit den Dämpfen kann es nützlich sein,
EMI2.1
Folge der Reaktion in dem Film entstehen können, zu neutralisieren.
Es ist auch möglich, diese Filme noch auf andere Weise anzubringen. Dies kann nämlich auch dadurch geschehen, dass diese flüssigen Siliziumverbindungen auf der Düse aufgebracht und aufgerieben werden. Auch dadurch entsteht der gewünschte Film.
Nach der britischen Patentschrift Nr. 575295 wird ein solcher Film mit Hilfe einer anderen Oberfläche angebracht, welche die Komplementärform des zu behandelnden Gegenstandes hat.
Die Komplementärfbrm wird mit einem Polyorganosiloxan versehen, wonach die zwei Oberflächen aufeinander gepresst werden. Die Absicht dabei ist, die Glas-oder Porzellanoberfläche wasserabstossend zu machen.
Unter den verschiedenen organischen SiliziumHalogenverbindungen, welche benutzt werden können, können die Alkyl-Silizium-Halogenver- bindungen, wie Methyl-, Aethyl-, Propyl-und Butylchlorid, oder die entsprechenden Bromide,

wie die Chlor-Silane, benutzt werden. Auch können Gemische, z. B. CHgSiCIg mit (CHaSiC verwendet werden.
Durch die Benutzung so behandelter Düsen zum Spinnen wird eine äusserst wichtige Verbesserung im Spinnvorgang erzielt.
Die Behandlung der Düsen kann unmittelbar vor der Benutzung oder lange Zeit vorher erfolgen.
PATENTANSPRÜCHE :
1. Verfahren zur Herstellung von Viskose- kunstseidefäden mit Hilfe eines säure-und salzhaltigen Spinnbades und unter Verwendung von einer mit einem Überzug bedeckten Spinndüse, dadurch gekennzeichnet, dass der Überzug aus einem Polyorganosiloxan besteht.

Spinning bath is insoluble. After the first contact with the fumes it can be useful to
EMI2.1
Consequence of the reaction in the film can be neutralized.
It is also possible to apply these films in other ways. This can be done by applying these liquid silicon compounds to the nozzle and rubbing them on. This also creates the desired film.
According to British Patent No. 575295, such a film is applied by means of another surface which has the complementary shape of the object to be treated.
The complementary mold is provided with a polyorganosiloxane, after which the two surfaces are pressed together. The intention is to make the glass or porcelain surface water repellent.
Among the various organic silicon-halogen compounds that can be used, the alkyl-silicon-halogen compounds, such as methyl, ethyl, propyl and butyl chloride, or the corresponding bromides,
EMI2.2
EMI2.3
such as the chlorosilanes. Mixtures, e.g. B. CHgSiCIg can be used with (CHaSiC.
By using nozzles treated in this way for spinning, an extremely important improvement in the spinning process is achieved.
The treatment of the nozzles can take place immediately before use or a long time beforehand.
PATENT CLAIMS:
1. A process for the production of viscose rayon threads with the aid of an acid and salt-containing spinning bath and using a spinneret covered with a coating, characterized in that the coating consists of a polyorganosiloxane.
