Description

Verfahren zur Herstellung von Fäden oder Fasern aus Lösungen von sauerstofffrei hergestellten Dichloräthylenpolymerisaten Nach dem Verfahren des Patents 884534 lassen sich beständige Lösungen von sauerstofffrei hergestellten Dichloräthylenpolymerisaten mit einem Gehalt von mindestens 75% as-Dichloräthylen in Tetrahydrofuran herstellen, indem man der Lösung reduzierende oder die Einwirkung von molekularem Sauerstoff unterbindende Stoffe zusetzt.Process for the production of threads or fibers from solutions of oxygen-free Dichlorethylene polymers produced by the method of patent 884534 stable solutions of oxygen-free dichloroethylene polymers can be used with a content of at least 75% as-dichloroethylene in tetrahydrofuran, by reducing the solution or by exposure to molecular oxygen Adding inhibiting substances.

Es wurde nun gefunden, daß man durch Verspinnen derartiger Lösungen hochwertige Fäden oder Fasern erzeugen kann. Das Verspinnen dieser Lösungen kann nach den üblichen Verfahren erfolgen. Durch Nachverstreckung der erhaltenen Fäden bei erhöhter Temperatur kann eine Erhöhung der Reißfestigkeit erzielt werden. Als besonders zweckmäßig hat sich das Verfahren des Patents 743 597 erwiesen, bei welchem in einem Arbeitsgang Fasern von hoher Zerreißfestigkeit erhalten werden.It has now been found that by spinning such solutions can produce high quality threads or fibers. Spinning these solutions can be carried out in accordance with the usual procedures. By post-drawing the threads obtained an increase in the tear strength can be achieved at elevated temperatures. as The method of patent 743 597 has proven to be particularly useful, in which Fibers of high tensile strength can be obtained in one operation.

Die nach diesem Verfahren hergestellten Produkte zeichnen sich durch eine bemerkenswerte Beständigkeit gegen Säuren üntl Laugen aus und haben vor den bekannten Polyvinylchloridfasern den Vorzug einer höheren Wärmebeständigkeit.The products manufactured by this process are characterized by a remarkable persistence against acids and bases and have the advantage of higher heat resistance over the known polyvinyl chloride fibers.

Die in dem nachstehenden Beispiel -angegebenen Teile sind Gewichtsteile.The parts given in the example below are parts by weight.

Beispiel 2o Teile eines unter Ausschluß von Sauerstoff hergestellten Mischpolymerisats aus 93% Dichloräthylen und 7% Acrylsäureäthylester werden in 8o Teilen Tetrahydrofuran, das o,5 % Hydrochinon enthält, gelöst. Diese Lösung wird durch eine Lochdüse in Wasser von 25° als Fällbad versponnen. Die Fällstrecke beträgt i8o cm. Nach der Fällstrecke sind drei Streckstäbe angeordnet, über welche der Faden geleitet wird, wobei eine Verstreckung um das 4- bis 5fache vorgenommen wird.Example 2o parts of a product prepared in the absence of oxygen Copolymer of 93% dichloroethylene and 7% ethyl acrylate are in 8o Parts of tetrahydrofuran, which contains 0.5% hydroquinone, dissolved. This solution will spun through a perforated nozzle in water at 25 ° as a precipitation bath. The felling distance is 18o cm. After the felling section, three stretching rods are arranged over which the thread is passed, with a stretching of 4 to 5 times is made.
