DEUTSCHESGERMAN
Die Erfindung betrifft ein Verfahren zum Veredeln von Textilgut aus Polyäthylenterephthalat. Die Veredlung, die sich unter anderem sowohl im Formfestmachen der genannten Gebilde als auch in einer Kräuselung der Fäden und Fasern auswirkt, wird durch eine Behandlung des Textilgutes mit chlorierten aliphatischen Kohlenwasserstoffen erreicht.The invention relates to a method for finishing textile material made of polyethylene terephthalate. The refinement, which, among other things, both in fixing the shape of the structures mentioned as well as in a The effect of crimping the threads and fibers is achieved by treating the textile material with chlorinated aliphatic hydrocarbons.
Es wurde bereits vorgeschlagen, Fäden oder Fasern aus synthetischen Polykondensaten mit gesättigtem Dampf oder mit einer inerten heißen Flüssigkeit zu behandeln. Es wird damit eine Schrumpfung und gleichzeitig eine Verbesserung der Formbeständigkeit erreicht. Diese Heißdampf- oder Heißluftbehandlung niuß bei sehr hohen Temperaturen und unter Druck durchgeführt werden, wenn man den gewünschten Effekt überhaupt erreichen will. Durch die relativ hohen Temperaturen ist allerdings eine Schädigung der Fäden und der daraus gefertigten Gebilde unvermeidbar. Die Fäden, insbesondere die Polyäthylenterephthalat-Fäden, werden durch diese Behandlung entweder teilweise abgebaut oder neigen zur Vergilbung, so daß in jedem Falle diese Art der Behandlung sich nachteilig auswirkt.It has already been proposed to use threads or fibers made of synthetic polycondensates with saturated Treat with steam or with an inert hot liquid. There will thus be a shrinkage and at the same time an improvement in dimensional stability is achieved. This superheated steam or hot air treatment Must be carried out at very high temperatures and under pressure if one can achieve the desired result Want to achieve an effect at all. Due to the relatively high temperatures, however, there is damage of the threads and the structures made from them are unavoidable. The threads, especially the polyethylene terephthalate threads, are either partially degraded by this treatment or tend to yellow, so that in each case this type of treatment has an adverse effect.
Bezüglich des Kräuseins von Fäden oder Fasern aus synthetischen Hochpolymeren hat man bereits vorgeschlagen, die Fäden nach dem Verstrecken in heiße Bäder einzubringen, welche aus wäßrigen Lösungen anorganischer oder organischer Salze bestehen. Weiterhin wurde vorgeschlagen, Lösungen von organischen oder anorganischen Säuren, wie Milchsäure, Glycolsäure, Chlorwasserstoffsäure, sowie von entsprechenden Salzen, wie Natriumlactat, Ammoniumchlorid, zum Kräuseln zu verwenden. Die genannten Kräuselungsbäder eignen sich indessen nur für das Kräuseln von Fäden bzw. Fasern aus Polyamiden. Wenn man die bei den Polyamiden bekanntgewordenen Erfahrungen auf Fäden oder Fasern, welche aus Polyäthylenterephthalat bestehen, übertragen will, so werden mit den genannten Bädern von anorganischen oder organischen Salzen bzw. Säuren keine oder nur sehr ungenügende Effekte erzielt.Concerning the crimping of threads or fibers made of synthetic high polymers one has already proposed to introduce the threads after drawing in hot baths, which from aqueous Solutions of inorganic or organic salts exist. Furthermore, it has been proposed solutions by organic or inorganic acids such as lactic acid, glycolic acid, hydrochloric acid, and of appropriate salts, such as sodium lactate, ammonium chloride, to be used for curling. the The crimping baths mentioned are only suitable for crimping threads or fibers made of polyamides. If one considers the experiences made with polyamides on threads or fibers, which consists of polyethylene terephthalate, wants to transfer, so are with the baths mentioned by inorganic or organic salts or acids achieved no or only very inadequate effects.
Es wurde gefunden, daß sich Textilgut aus Polyäthylenterephthalat, welches in Form von Fäden,
Fasern bzw. daraus gefertigten textlien Gebilden vorliegt, in besonders vorteilhafter Weise veredeln läßt,
wenn man das Textilgut mit chlorierten aliphatischen Kohlenwasserstoffen bei Temperaturen zwischen 40
und 80° C bis zu 10 Minuten behandelt. Die Veredlung wirkt sich dahingehend aus, daß überraschenderweise
durch die Art der Behandlung ein starker Schrumpf des Textilgutes eintritt, der unter anderem
eine Verbesserung des Formfestmachens bedeutet. Neben der Verbesserung des Formfestmachens wird
gleichfalls eine Versteifung der Faser erreicht, so daß Verfahren zum Veredeln
von Polyäthylenterephthalat-Fäden,
-Fasern bzw. daraus gefertigten
textlien GebildenIt has been found that textile material made of polyethylene terephthalate, which is in the form of threads, fibers or textile structures made therefrom, can be refined in a particularly advantageous manner if the textile material is upgraded with chlorinated aliphatic hydrocarbons at temperatures between 40 and 80 ° C Treated 10 minutes. The effect of the refinement is that, surprisingly, the type of treatment causes severe shrinkage of the textile material, which means, among other things, an improvement in the form-setting. In addition to improving the shape setting, a stiffening of the fiber is also achieved, so that processes for finishing

ihre Verarbeitung auf der Karde begünstigt wird. Gleichzeitig tritt auch eine leichte Aufrauhung der Oberfläche ein, welche die Aufnahmefähigkeit für die Avivage verbessert, so daß die Verarbeitung glatt verläuft. Weiterhin gelingt es, Fäden und Fasern aus Polyäthylenterephthalat zu kräuseln, wenn sie der erfindungsgemäßen Behandlung unterworfen werden.their processing on the card is favored. At the same time there is also a slight roughening of the A surface, which improves the absorption capacity for the finishing agent, so that the processing is smooth runs. Furthermore, it is possible to crimp threads and fibers made of polyethylene terephthalate when they treatment according to the invention are subjected.
Die Wirkung der Behandlung ist im wesentlichen darauf zurückzuführen, daß die in den Polyestern enthaltenen cyclischen trimeren Glycolterephthalate durch die chlorierten Kohlenwasserstoffe extrahiert werden. Diese cyclischen Trimeren sind in den chlorierten Kohlenwasserstoffen löslich, so daß sie aus dem Textilgut herausgelöst werden. Der Befund, daß durch eine kurzfristige Behandlung von textlien Polyäthylenterephthalatgebilden mit chlorierten aliphatischen Kohlenwasserstoffen eine Veredlung eintritt, ist insofern überraschend, als die gleiche Behandlung bei anderen synthetischen Fäden bzw. Fasern, z. B. bei Polyamiden, zu keinem Ergebnis führt. Werden z. B. Polyamide mit chlorierten Kohlenwasserstoffen behandelt, so tritt ein Schrumpf überhaupt nicht ein.The effect of the treatment is essentially due to that in the polyesters contained cyclic trimeric glycol terephthalate extracted by the chlorinated hydrocarbons will. These cyclic trimers are soluble in the chlorinated hydrocarbons, so they can be extracted from the textile material. The finding that through a short-term treatment of textlien Polyethylene terephthalate structures with chlorinated aliphatic hydrocarbons are upgraded, is surprising in that the same treatment was used for other synthetic threads or threads. Fibers, e.g. B. with polyamides, leads to no result. Are z. B. polyamides with chlorinated hydrocarbons treated, shrinkage does not occur at all.
Es sind insbesondere folgende chlorierte aliphatische Kohlenwasserstoffe für die Behandlung des Polyäthylenterephthalat-Textilgutes wirksam: Chloroform, Trichloräthylen, Dichlorbutan, Tetrachlorbutan, s-Dichloräthylen, 1,2-Dichloräthan, Pentachloräthan u. a. Die Behandlungsdauer muß auf einen relativ kurzen Zeitraum, und zwar bis zu 10 Minuten, beschränkt bleiben. Es ist bereits möglich, eine gute Wirkung bei einer Einwirkungsdauer von 2 bis 6 Mi-There are in particular the following chlorinated aliphatic hydrocarbons for the treatment of the Effective polyethylene terephthalate textile goods: chloroform, trichlorethylene, dichlorobutane, tetrachlorobutane, s-dichloroethylene, 1,2-dichloroethane, pentachloroethane and others. The duration of treatment must be relative short period of time, namely up to 10 minutes. It is already possible to have a good one Effect with an exposure time of 2 to 6 minutes
