Description

Verfahren zur Herstellung von Kunstseide nach dem Viskoseverfahren. Es hat sich ergeben, daß ein Fällbad, welches aus Natriumbisülfit besteht, besonders wirksam dadurch gemacht wird, wenn ihm Magnesiumsulfat zugemischt wird, wobei offenbar eine kombinierte Wirkung der schwachen schwefligen Saure einerseits und der aussalzenden Wirkung des Salzes andererseits zustande kommt.Process for the production of rayon using the viscose process. It has been found that a precipitation bath, which consists of sodium bisulfite, is particularly good is made effective by adding magnesium sulfate to it, apparently a combined effect of the weak sulphurous acid on the one hand and the salting out Effect of the salt on the other hand comes about.

Die Vorteile dieser neuen Methode bestehen darin, daß ein Faden entsteht, der eine besonders hohe Festigkeit und Dehnung hat. Die Viskoselösungen selbst dürfen nicht zu jung sein.The advantages of this new method are that a thread is created which has a particularly high strength and elongation. The viscose solutions themselves are allowed don't be too young.

Die Ausführung des Verfahrens geschieht so, daß man ein Fällbad herstellt, welches aus 15 1 einer Natriumbisulfitlauge besteht mit einem spez. Gewicht 1,33 und in. welchem 7 kg krist. Magnesiumsulfat gelöst ist. Das spez. Gewicht des Fällbades ist r,38o. Die geeignete Spinntemperatur liegt zwischen 40 und 5o°.The process is carried out in such a way that a precipitation bath is produced which consists of 15 l of sodium bisulfite lye with a spec. Weight 1.33 and in which 7 kg crystall. Magnesium sulfate is dissolved. The spec. The weight of the felling bath is r, 38o. The suitable spinning temperature is between 40 and 50 °.

Die Herstellung des Fadens geschieht im übrigen in bekannter Weise.The thread is also produced in a known manner.
