Description
Verfahren zum Verspinnen von Vinylchlorid- und as. Dichloräthylen-Mischpolymerisaten Die Mischpolymerisate aus Vinylchlorid und as. Dichloräthylen besitzen bekanntlich gute physikalische Eigenschaften, wie große Biegsamkeit und Zug- bzw. Reißfestigkeit. Ein Nachteil dieser Mischpolymerisate ist, daß es bisher nicht möglich war, sie im Trokkenspinnverfahren zu Fäden zu verarbeiten, da das Mischpolymerisat in den bekannten organischen Lösungsmitteln nur unvollständig löslich st. So konnte man insbesondere die hochpolymerisierten Mischpolymer.isate aus Vinylchlorid und as. Dichloräthylen nur -im Schmelzfluß unter Druck verspinnen. Dies Verfahren gibt naturgemäß nur verhältnis= mäßig dicke Fäden oder Borsten.Process for spinning vinyl chloride and as. Dichloroethylene copolymers The copolymers of vinyl chloride and as. Dichlorethylene are known to have good physical properties, such as great flexibility and tensile or tear strength. A disadvantage of these copolymers is that it has not previously been possible to use them to process into threads in the dry spinning process, since the copolymer in the known organic solvents only incompletely soluble st. So you could especially the highly polymerized mixed polymers made of vinyl chloride and as. Spin dichloroethylene only in melt flow under pressure. This procedure is there naturally only proportionally = moderately thick threads or bristles.
Es wurde nun gefunden, daß Mischpolyinerisate aus Vinylchlorid und as. Dichloräthylen, bei denen der Gehalt an Dichloräthvlen j °@`o bis 25 °/o beträgt, sich gut in Tatrahydrofuran lösen, und daß sich diese Lösungen nach dein bekannten Trockenspinnverfahren zu sehr feinen Kunstfäden verspinnen lassen.It has now been found that copolymers of vinyl chloride and as. Dichloroethylene, in which the dichloroethylene content is from 0 to 25 %, dissolve well in Tatrahydrofuran, and that these solutions are too fine by the known dry spinning process Let artificial threads spin.
Die :Mischpolymerisate gestatten die Herstellung auch sehr hochkonzentrierter Lösungen; so macht es z. B. keine Schwierigkeiten. Lösungen jed-er gewünschten Konzentration herzustellen, so daß man jeweils. mühelos die für den Trockenspinnprozeß notwendige Spinnlösung mit dem gewünschten Gehalt an Mischpolymerisat erhalten kann.The: Copolymers allow very highly concentrated production Solutions; so it does z. B. no difficulties. Solutions of any concentration required manufacture so that one each. effortlessly the necessary for the dry spinning process Can get spinning solution with the desired content of copolymer.
Es ist schon vorgeschlagen worden, Mischpolyinerisate aus V1nvIChlorld und 2o °;. bis 8o °,1o as. Dichloräthyien herzustellen, die eine gute Löslichkeit in organischen Lösungsmitteln zeigen sollen. _Ms Lösungsni.ittelgemisch mit besonderer Lösefähigkeit wird eine Mischung aus Butylacetat, Benzol und Aceton genannt. Weder-dies Gemisch noch seine einzelnen Komponenten sind jedoch imstande, ein Mischpolymerisat von -\Tinvlchlorid und 5 Otfo bis a5 °/o as. Dichloräthylen so zu lösen, daß die Lösung versponnen werden kann. Gerade aber Fäden aus diesen Mischpolyinerisaten zeigen besonders gute Festigkeits-und Dehnungsei enschaften. Irin so überraschender ist es, daß Polvvinvl- und Dichloräthylen -Mischpolymerisate mit einemDichloräthylengelialt bis zu 1J4 des zu lösenden Stoffes sich mühelos. in Tetrahydrofuran lösen lassen.It has already been proposed to use mixed polymers from V1nvIChlorld and 2o ° ;. to 8o °, 1o as. Dichloroethyien to produce, which should show good solubility in organic solvents. A mixture of butyl acetate, benzene and acetone is called a mixture of solvents with particular solubility. Neither this mixture nor its individual components, however, are capable of dissolving a copolymer of - \ Tinvlchlorid and 5 % to a5% as. Dichloroethylene in such a way that the solution can be spun. However, it is precisely threads made from these copolymers that show particularly good strength and elongation properties. It is so surprising that polyvinyl and dichloroethylene copolymers can easily be mixed with a dichloroethylene gel of up to 1/4 of the substance to be dissolved. let dissolve in tetrahydrofuran.
Beispiel Ein in bekannter Weise hergestelltes Mischpolymerisat aus go °% Vinylchlorid und io.°,1« as. Dichloräthylen wird in Tetrahydrofu@: gelöst, so daß eine 35 °/°ige Lösung des Ili polymerisates von der spez. Viscosität o gemessen in o.i °%igerLösung, entsteht. Diese Lösung wird in einer Trockenspinnapparatur versponnen. Die Düsenkopftemperatur beträgt 67 °, die Zellentemperatur 125°, der Abzug erfolgt mit einer Geschwindigkeit von 22o in;! inin. Zur Anwendung kommen Düsen mit 32 Löchern und einem Durchmesser von o,o6 nim.Example A copolymer produced in a known manner from % vinyl chloride and io. °, 1% as. dichloroethylene is dissolved in tetrahydrofluorine, so that a 35 ° / ° solution of the Ili polymer of the spec. Viscosity measured o in o.i °% solution, arises. This solution is in a dry spinning apparatus spun. The nozzle head temperature is 67 °, the cell temperature 125 °, the Triggered at a speed of 22o in ;! inin. Come to use Nozzles with 32 holes and a diameter of 0.06 inches.
Der so gesponnene Faden hat einen Titer von N", etwa 55. Dieser Faden wird mit igo Drehungen gezwirnt und nach dein Zwirnen um 150% verstreckt. Vor oder beim Verstrecken wird der Faden durch ein Wasserbad von 70° geleitet. Der endgültig erhaltene Faden hat einen Titer von NCR 140, eine Reißlänge von 15,3 km und eine Dehnung von 14 °%.The thread spun in this way has a titer of N ", about 55. This thread is twisted with igo turns and after twisting it is stretched by 150%. Before or during stretching, the thread is passed through a water bath at 70 °. The thread finally obtained has a titre of NCR 140, a tenacity of 15.3 km and an elongation of 14%.
Die Lösungen des Mischpolynierisates aus Vinylchlorid und as. Dichloräthylen lassen sich auch zum Gießen von Filmen, Herstellen von Hohlkörpern und als Überzüge verwenden.The solutions of the mixed polymer from vinyl chloride and as. Dichloroethylene can also be used for casting films, producing hollow bodies and as coatings use.
