Description

DEUTSCHESGERMAN

Gegenstand der Hauptpatentanmeldung V10789 lVc/29b ist ein Verfahren zur Herstellung von feinen Fäden aus hochmolekularen aliphatischen Niederdruck-Polyolefinen. Die Polymerisate aus aliphatischen Olefinen mit 2 bis 5 C-Atomen werden in ölen zu einer höchstens 18°/oigen Lösung gelöst und nach dem Naßspinnverfahren verarbeitet. Als Fällbäder werden Alkohole oder Äther bzw. Gemische von beiden verwendet. Das Verfahren wird in der Weise geführt, daß die Fäden nach dem Austritt aus der Düse eine kurze Luftstrecke von 5 bis 10 cm durchlaufen, ehe sie in das Fällbad eintreten. Anschließend erfolgt eine Verstreckung in zwei Stufen, und zwar eine Vorverstreckung bei Temperaturen zwischen 90 und 105° C und eine zweite Verstreckung bei Temperaturen über 110° C. Die Restmenge des Lösungsmittels wird mittels Petroläther ausgewaschen.The subject of the main patent application V10789 IVc / 29b is a process for the production of fine threads made of high molecular weight aliphatic low pressure polyolefins. The polymers made from aliphatic Olefins with 2 to 5 carbon atoms are dissolved in oils to form a maximum 18% solution and processed according to the wet spinning process. Alcohols or ethers or mixtures of are used as precipitation baths both used. The process is carried out in such a way that the threads after exiting from the Pass the nozzle through a short air gap of 5 to 10 cm before entering the precipitation bath. Afterward stretching takes place in two stages, namely pre-stretching at temperatures between 90 ° and 105 ° C and a second stretching at temperatures above 110 ° C. The remainder of the solvent is washed out with petroleum ether.

Bei der Verarbeitung von Polyäthylenlösungen hat sich ein Fällbad aus Propanol (20° C) besonders bewährt. Die Aufgabe dieses Fällbades besteht darin, so dem Faden durch Entzug eines Teils des Lösungsmittels die anteilige Festigkeit für eine weitere Verarbeitung zu geben. Es ist dabei vorteilhaft und auch bei ähnlichen Spinnverfahren bekannt, dem Faden bereits im Fällbad den Hauptteil des Lösungsmittels zu entziehen. Allerdings darf der Lösungsmittelentzug nicht zu rasch erfolgen, da dies für die Fadenbildung ungünstig wäre. Ein ungenügender Entzug von Lösungsmittel dagegen ergibt bei den meisten Naßspinnverfahren einen noch nicht fertigen Faden, der zu Verklebungen neigt und sich zu leicht deformieren läßt.When processing polyethylene solutions, a precipitation bath made of propanol (20 ° C) has proven particularly useful. The task of this precipitation bath is to remove part of the solvent from the thread to give the proportional strength for further processing. It is beneficial in the process and also known in similar spinning processes, the thread already in the precipitation bath to the main part of the solvent revoke. However, the removal of solvent must not be too rapid, as this will cause thread formation would be inconvenient. In contrast, insufficient removal of solvent results in most wet spinning processes a thread that is not yet finished, tends to stick and can be deformed too easily.

Es wurde nun gefunden, daß sich das Verfahren der Hauptpatentanmeldung V 10789 IVc/29b noch günstiger durchführen läßt, wenn die heiße Spinnlösung nach dem Verlassen der Düse durch Einführen in ein H2O-Bad gesponnen und dabei rasch abgekühlt wird, wobei praktisch kein Lösungsmittelentzug erfolgt, und erst nach Verlassen dieses Fällbades in einem Waschrohr ein Teil des Lösungsmittels entfernt wird. Anschließend erfolgen eine Vorverstreckung und schließlich das vollständige Auswaschen des Lösungsmittels und sodann die Endverstreckung. In den beiden Waschstufen wird mit Methylenchlorid als Waschmittel gearbeitet. Der Vorteil der vorliegenden Arbeitsweise gegenüber der Hauptpatentanmeldung liegt darin, daß sich das Verfahren durch die Verwendung von Wasser an Stelle von Propanol wesentlich billiger gestaltet und darüber hinaus Methylenchlorid an Stelle des in der Hauptpatentanmeldung beschriebenen Petroläthers jede Explosionsgefahr aus-It has now been found that the process of the main patent application V 10789 IVc / 29b can be carried out even more favorably if the hot spinning solution is spun by introducing it into an H 2 O bath after leaving the nozzle and is cooled rapidly, with practically no solvent removal takes place, and only after leaving this precipitation bath is part of the solvent removed in a washing tube. This is followed by pre-stretching and finally the complete washing out of the solvent and then final stretching. Methylene chloride is used as the detergent in the two washing stages. The advantage of the present procedure compared to the main patent application is that the process is much cheaper by using water instead of propanol and, moreover, methylene chloride instead of the petroleum ether described in the main patent application eliminates any risk of explosion.

Auf dem Wege von der Spinndüse bis zum Eintritt in das kalte Wasserbad, d. h. auf einer Luftstrecke von etwa 10 cm, werden durch Verdampfen bzw. Ausschwitzen etwa 5% des Lösungsmittels abgegeben. Im Wasserbad selbst bleibt der Paraffinölgehalt des Fadens praktisch konstant und beträgt hier also 80%. Die Polyäthylenlösung erstarrt im H2O-Bad und bildet einen festen Faden, der eine so hohe mechanische Festigkeit besitzt, daß er sich von den üblichen Abzugsmaschinen abziehen läßt. Bei der nachgeschalteten Wäsche in einem mit Methylenchlorid gefüllten Waschrohr sinkt der Paraffmölgehalt auf 55% ab. Die anschließende Vorverstreckung im Verhältnis 1 :1 in heißem Wasser (95 bis 98° C) bewirkt einen weiteren geringeren Lösungsmittelentzug auf 50 bis 48%. Die Restlösungsmittelmenge wird in einem zweiten Waschrohr ebenfalls mittels Methylenchlorid entfernt, auf einen Restgehalt von 0,5 bis 1%. Der Faden wird nunmehr nochmals um das Vierfache verstreckt. is practically free of aromatics and has a boiling point of 220 to 225 ° C) dissolved to a 15% solution. On the way from the spinneret to the entry into the cold water bath, ie over an air gap of about 10 cm, about 5% of the solvent is given off by evaporation or exudation. In the water bath itself, the paraffin oil content of the thread remains practically constant and is 80% here. The polyethylene solution solidifies in the H 2 O bath and forms a solid thread which has such a high mechanical strength that it can be pulled off by conventional haul-off machines. During the subsequent washing in a washing tube filled with methylene chloride, the paraffin oil content drops to 55%. The subsequent pre-stretching in a ratio of 1: 1 in hot water (95 to 98 ° C.) results in a further lower solvent removal to 50 to 48%. The residual amount of solvent is removed in a second washing tube, likewise using methylene chloride, to a residual content of 0.5 to 1%. The thread is now stretched four times again.
