Description

Verfahren zur Nachbehandlung von Textilfäden aus linearen Hochpolymeren auf Basis von s-Caprolactam Lineare Hochpolymere, welche aus a-Cap@rolactam hergestellt sind, enthalten gewisse Mengen schwer wasserlöslicher, niedrigpolymerer oder monomere,r Anteile, die sich, bei der textilen Verarbeitung von Fäden sehr nachteilig auswirken könnten.. Diel niedrigmoleleu;laren Anteile scheiden sich auf den Fäden ab- und führen bei der Weiterverarbeitung, z. B. in dser Wirkerei oder Weberei, zu Störungen, welche eine einwandfreie Verarbeitung des Guteis unmöglich machen.Process for the aftertreatment of textile threads made of linear high polymers based on s-Caprolactam Linear high polymers, which are made from a-Cap @ rolactam contain certain amounts of poorly water-soluble, low-polymer or monomeric, r Proportions that have a very detrimental effect on the textile processing of threads could .. The low molecular weight portions are deposited on the threads and lead in further processing, e.g. B. in knitting or weaving, to disturbances, which make perfect processing of the ice cream impossible.

Es ist bereits bekannt, geformte Gebilde aus derartigem monomere oder niedrgmo@lekulare Bestandteile enthaltendem Polyamiden durch Behandeln mit Wasser zu, befreien. Bei Textilfädn jedoch läßt sich dieses Verfahren. schwer mit denn üblichen Verarbeitungsverfahren vor-knüpfen, da wiegen: der verhältnismäßig geringem. Wasserlöslichkeit der niedrigmolekularen Verbindungen zum Auswaschen großer Wassermengen nötig sind und außerdlem die Beh andlungsdaüer bis zur restlosen Entfernung der unerwünschten, Nebenproduktei er@-hebliche Zeiträume in Anspruch nimmt. Da die Fäden auf der Spule nicht einwandfrei von, nied.'rigpo:lymeren Anteilsem gereinigt werden können, ist es außerdem. notwendig, die Fäden in Strangform zu bringen, da, in dieser Form ein schnelleres und besseres Auswaschen der Fäden. mdglich ist. Dies bedingt jedoch einen zusätzlichen Arbeitsgang und ist deshalb für die technische Durchführung des VeTfahrens nachteilig. Es wurde nun gefunden, daß die Entfexnung der niedrigmolekularen bzw. monomeren Anteile in Fäden aus derartigen linearen Hochpolymeren dadurch ganz erheblich verbessert und beschleunigt werden. kann; daß man die Fäden auf der Spule kurze Zeit mit heißem Wasser behandelt und alsdann, auf der Spule ausschleudert.It is already known, formed from such monomeric or Polyamides containing low molecular weight components by treatment with water to free. In the case of textile threads, however, this method can be used. difficult with then usual processing methods, because weigh: the relatively low. Water solubility of the low molecular weight compounds for washing out large amounts of water are necessary and also the duration of the treatment until the complete removal of the unwanted, by-products if it takes a considerable amount of time. Because the threads on the bobbin cannot be properly cleaned of low-polymer components can, it is also. necessary to bring the threads in strand form, there, in this one Form a faster and better washing out of the threads. possible is. However, this requires an additional operation and is therefore for the technical implementation of the process disadvantageous. It has now been found that the Defection of the low molecular weight or monomeric fractions in threads made of such linear high polymers can be significantly improved and accelerated. can; that the threads on the bobbin are treated with hot water for a short time and then, flung out on the bobbin.

Das-Ausschleudern von Textilfäden aus Viskoseseide auf Spulen zwecks Entfernung des Waschwassers ist an: sich bekannt (Patentschrift q.q.o 279).The spin-out of textile threads made of viscose silk on bobbins for the purpose Removal of the washing water is known per se (patent specification q.q.o 279).

Die Wirkung des Ausschleuderns, welches bei den genannten Polyamiden eine restlose Beseitigung der monomeren und niedri.gpolymeren Anteile in den Fäden hervorruft, ist überraschend, denn es konnte zwar nach dem Bekannten vorausgesehen werden,, daß das Ausschleudarn eine Trocknung der Fäden mit sich beingt, nicht aber, daß die an sich schwer löslichen monomeren und polymeren Anteile hierdurch praktisch vollständig entfernt werden. Das, neun Verfahren bringt wesentliche Vorteile durch die Verkürzung der Nachbehandlungszeit, da für die Heißwasserbehandlung ein Bruchteil der bishear dafür angesetzten Zeit genügt. Da die monorneren und niedrigpolymeren Anteile praktisch vollständig entfernt werden, bringt das Verfahren gleichzeitig die Behebung aller Schwierigkeiten bei der textilen Weiterverarbeitung sowie eine Verbesserung dein Qualität der erhaltenen Fäden. Es tritt keine Streifigkeit oder Weißspri.tzigkeit der daraus. gefertigten Textilien mehr ein. Auch die färberöschen Eigenschaften der Fäden sind wesentlich vereinheitlicht und damit verbessert. Überdies wirdl die Zeit, welche zur Trocknung der Spule benötigt wird, auf etwa, ein Fünftel der ohne Aus.schleudern üblichen Trockenzeit vermindert.The effect of centrifuging, which is the case with the polyamides mentioned a complete elimination of the monomeric and low-polymer components in the threads causes is surprising, because it could indeed be foreseen according to the known be, that the Ausleudarn a drying of the threads with it, but not, that the poorly soluble monomeric and polymeric fractions thereby become practical completely removed. The nine procedures bring about significant advantages the shortening of the post-treatment time, since a fraction for the hot water treatment the time allotted for this is sufficient. As the monomeric and low polymer Fractions are practically completely removed, brings the process at the same time the elimination of all difficulties in textile processing as well as a Improvement of the quality of the threads obtained. There is no streaking or White spray from it. manufactured textiles. Also the dye florets The properties of the threads are essentially standardized and thus improved. Besides the time it takes to dry the bobbin is about one fifth the usual drying time without centrifuging is reduced.

Das Verfahren hat überdies noch den Vorteil, daß durch das Schleudern, der auf der Spule befindliche Seidenwickel etwas. gelockert wird, so daß beim nachträglichen Trocknen der Faden, gleich, mäßiger schrumpft, als wenn; das Trocknen ohne vorheriges Schleudern. durchgeführt wird.The method also has the advantage that by spinning, the silk wrap on the bobbin a little. is loosened, so that with subsequent Drying the thread, evenly, shrinks more moderately than when; drying without prior Sling. is carried out.

Beispiel Eine aus polymerem a-Caprolaatam gesponnene Kunstseide der Nm, 225/I6 wird während des Zwirneis auf Hülsen. dar üblichenAusführung aufgewickelt. Die auf der Spule befindliche Kunstseide wird 3o bis 6o Minuten mit Wasser von 90 bis. 95° behandelt und anschließend in einer normalen Strangschleuder 5 bis 15 Minuten lang ausgeschleudert Nach denn Schleudern wird das Material 2 bis q. Stunden bei 95 bis ioo° ge trocknet. Die Sende zeigt nach der Trocknung ein glänzendes Aussehen und, keine Abscheidung niedrigpolymerer Anteile.Example A rayon of Nm, 225/16 spun from polymeric a-Caprolaatam is twisted onto sleeves. the usual design. The rayon on the bobbin is dipped in water for 90 to 30 minutes. 95 ° and then centrifuged in a normal extruder for 5 to 15 minutes. After the spinning, the material is 2 to q. Hours at 95 to 100 ° ge dried. After drying, the transmission shows a glossy appearance and no deposition of low-polymer components.

Ein gleichbehandeltes Material, dies nicht ausgeschleudert wird, zeigt mach entsprechend längerer Trockenzeit (i2 bis 15 Stunden bei 95 bis, ioo°) ein mattes Aussehen und. starke Abscheidung niedrigpolymerer Anteile.A material treated in the same way, which is not centrifuged, shows allow a longer drying time (i2 to 15 hours at 95 to, ioo °) matte appearance and. strong deposition of low polymer components.
