Description

Verfahren zur Herstellung von gekräuselten Kunstseidefäden beim Spinntopfspinnen Gegenstand des Patents 654 Soo ist ein Verfahren zur Herstellung von gekräuselten Kunstseidefäden beim Spinntopfspinnen, das darin besteht, daß der Faden von einem zur Achsenlinie des Spinntopfes exzentrisch gelegenen Punkt aus in den Spinntopf eingeführt wird.Process for the production of crimped rayon threads in spinning pot spinning The subject of patent 654 Soo is a method of making crimped Rayon threads in the spinning pot spinning, which consists in the fact that the thread of a point eccentrically to the axis line of the spinning pot into the spinning pot is introduced.

Es wurde nun gefunden, daß man die Kräuselung,@ insbesondere hinsichtlich ihrer Dauerhaftigkeit, noch verbessern kann, wenn man Fäden in möglichst plastischem Zustande, also noch wenig fixiert (was durch entsprechende Zusammensetzung und Reifung der Viscose sowie Einstellung von Säuregehalt und Temperatur des Spinnbades in bekannter Weise erzielt werden kann), dein Kräuselverfahren gemäß dem Hauptpatent 654 Soo unterwirft und dann diese Fäden vor der Weiterbehandlung zunächst in einem sauren Bad, das z. B. 5 bis 7 % der Schwefelsäure enthält, nachfixiert.It has now been found that the crimp, in particular with regard to its durability, can be improved if threads are fixed in the most plastic state possible, i.e. still little fixed (which is achieved by appropriate composition and ripening of the viscose as well as setting the acid content and temperature of the spinning bath in known way can be achieved), the crimping process according to the main patent 654 Soo and then these threads before further treatment first in an acidic bath, the z. B. contains 5 to 7 % of the sulfuric acid, post-fixed.

Es ist zwar schon bekannt, noch nicht oder nur unvollkommen fixierte Fasern durch Behandlung in einem Fixierbad und durch anschließendes Trocknen in gekräuseltem "Zustand überzuführen. Hierbei handelt es sich jedoch darum, die Fasern aus der schlichten, glatten Form in die gekräuselte überzuführen, wobei dem Trockenvorgang die entscheidende Wirkung zufällt. Es findet eine Kräuselung der glatten Faser, also ein wirklicher Kräuselvorgang, statt. Ein solcher kommt aber bei der vorliegenden Erfindung überhaupt nicht mehr in Betracht, da die Fäden bereits in einer gemäß dem Verfahren des Hauptpatent erzeugten, vollkommen gekräuselten Form vorliegen und daher keiner weiteren Formveränderung bedürfen. Unter den Bedingungen des Verfahrens der vorliegenden Erfindung, wobei es übrigens auf eine anschließende Trocknung überhaupt nicht wesentlich ankommt, bewirkt das Fixierbad lediglich eine Verfestigung der bereits vorhandenen Kräuselform.It is already known, not yet or only imperfectly fixed Fibers by treating them in a fixer and then drying them in curled "state. However, this is about the fibers from the simple, smooth shape to the ruffled one, with the drying process the decisive effect falls on. There is a curl of the smooth fiber, so a real curling process takes place. But this is the case with the present one Invention no longer considered at all, since the threads are already in a according to the process of the main patent produced perfectly curled shape and therefore do not require any further changes in shape. Under the terms of the procedure of the present invention, incidentally, there is a subsequent drying at all does not matter much, the fixer only causes a solidification of the already existing curling shape.

Der technische Fortschritt und die überraschende Wirkung des neuen Verfahrens bestehen darin, daß die Kräuselung beständiger und die gekräuselte Fadenmasse elastischer und wollähnlicher wird. Diese Wirkung ist offenbar dem fixierenden Einftuß des Säurebades auf die innere Kolloidalstruktur des Fadengebildes zuzuschreiben.The technical progress and the surprising effect of the new one Method consist in making the crimp more permanent and the crimped thread mass becomes more elastic and wool-like. This effect is evidently the fixing influence of the acid bath to the inner colloidal structure of the thread structure.
