Description
Verfahren zur Verbesserung der Spinnfähigkeit von Zellwolle ans regenerierter Cellulose Bei der Herstellung der Zellwolic aus regenerierter Cellulose kann nie ganz vermieden werden, daß einzelne Kapillarfäden nach dem Austreten der Celluloselösungen aus den Spinnbrausen im Spinntrichter oder im Fällbad aneinanderkleben.Process to improve the spinnability of rayon from the regenerated Cellulose In the production of Zellwolic from regenerated cellulose can never it is completely avoided that individual capillary threads after the cellulose solutions have emerged stick together from the spinnerets in the spinning funnel or in the felling bath.
Diese Verklebungen der Einzelfäden bedeuten einen großen Übelstand und beeinträchtigen die Verspinnbarkeit von kurzstapeligen künstlichen Fasergebilden außerordentlich.This sticking together of the individual threads is a major problem and impair the spinnability of short-staple artificial fiber structures extraordinary.
Es wurde nun gefunden, daß es möglich ist, dieVerklebungen weitgehend herabzudrücken, wenn die Zellwolle nach dem Fällen und. Spülen in einem Bade behandelt wird, das hochmolekulare Alkyläther von Oxalkylaminen bzw. deren Salze enthält.It has now been found that it is possible to largely remove the bonds to press down when the rayon after felling and. Rinse treated in a bath contains the high molecular weight alkyl ethers of oxyalkylamines or their salts.
Die hochmolekularen Allcyläther von Oxalkylaniinen besitzen die bemerkenswerte Fähigkeit, diese Verklebun@gen aufzuheben; die aneinanderhaftenden Einzelfäden -lassen sich nach der Behandlung leicht voneinander lösen und setzen der nachfolgenden mechani= schen Behandlung beim Krempeln oder beim Kämmen, je nach der Verwendung der Zellwolle, keinen Widerstand entgegen.The high molecular weight alkyl ethers of Oxalkylaniinen have the remarkable Ability to break these adhesions; leave the single threads sticking together easily separate from each other after the treatment and set the following mechani = treatment during carding or combing, depending on the use of the rayon, no resistance.
Die derart behandelten Zellwollen liefern daher noppenfreie Gespinste, und die Abfälle, die bei der Verarbeitung von Zellwolle reit hohen Verklebungszahlen in der Spinnerei oder Kämmerei recht beträchtlich waren, können auf -ein Mindestmaß herabgedrückt werden.The pulp treated in this way therefore provides pimple-free webs, and the waste generated in the processing of rayon has high sticking rates were quite considerable in spinning or combing, can be reduced to a minimum be depressed.
Wenn man früher schon insbesondere Celluloseacetatgespinste vor dem Zerschneiden zu Stapelfaser. mit Alkylolaminen oder einzelnen Verbindungen derselben, wie- Salze, Seifen, Ester, behandelt hat, so geschah das zu dem Zweck, die Schlüpfrigkeit der Fasern für das nachfolgende Spinnen zu verringern. Die besondere Bedeutung, die die hochmolekularen Alkyläther der Alkylolamine für die Aufhebung der Verklebungen besitzen, war bisher nicht erkannt worden.If you have already used cellulose acetate spun before the Cut into staple fiber. with alkylolamines or individual compounds thereof, like salts, soaps, and esters, so it was done for the purpose of slipperiness of fibers for subsequent spinning. The special meaning which the high molecular alkyl ethers of the alkylolamines for the lifting of the sticking own, had not previously been recognized.
Das Verfahren soll durch folgendes Beispiel näher erläutert werden, wobei ausdrücklich darauf hingewiesen wird, daß das Verfahren nicht auf diese Ausführungsform allein beschränkt bleiben soll: Zellwolle aus Viscose, die durch Brausen mit etwa 300o Öffnungen versponnen worden: ist, wird entschwefelt und gewaschen un-l hierauf bei 6o° in einem Bade behandelt, das 2,0 g ameisensaures Salz des Dicetyläthers des Triäthanolamins enthält. Die Zellwolle verbleibt etwa 15 Minuten in dem warmen Bad, tvird dann abgeschleudert und getrocknet. Die Verklebungszahl der Zellwolle wird dadurch gegenüber einer normalen Behandlung um vermindert.The procedure is to be explained in more detail by the following example, being explicit It should be noted that the procedure is not should remain limited to this embodiment alone: viscose rayon, which has been spun through showers with around 300o openings: is desulphurised and washed and then treated at 60 ° in a bath containing 2.0 g of formic acid Contains dicetyl ether salt of triethanolamine. The rayon remains about 15 minutes in the warm bath, then spun off and dried. The number of bonds This reduces the amount of rayon compared to normal treatment.
In gleicher Weise kann auch der Cetyläther des Diäthanolamins verwendet werden.The cetyl ether of diethanolamine can also be used in the same way will.
Die Behandlung läßt sich gleich vorteilhaft auf ähnliche Fasern aus regenerierter Cellulose, wie gröbere Stapelfaser,- geschnittene Kunstseide bzw. Kunstseidenabfall,anwenden.The treatment can be applied equally advantageously to similar fibers regenerated cellulose, such as coarser staple fibers, - cut rayon resp. Use rayon waste.
Die Behandlung mit den hochmalekularen Alkyläthern von Oxalkylaminen bzw. deren Salzen verleiht der Zellwolle gleichzeitig eine hohe Weichheit, die in vielen Fällen nicht in diesem Maße erwünscht ist. Es ist daher unter Umständen notwendig,, den Behan<ilungsbädern noch Zusätze zuzugeben, die die Weichheit der behandelten Zellwolle etwas herabdrücken, insbesondere läßt sich das durch geringe Zusätze von Eiweißstoffen, Kohlehydraten, Seifen, Fettsulfonsäureverbindungen und ähnlichen. Körpern mit Leichtigkeit erreichen. Diese Zusätze werden bestimmt durch den Verwendungszweck, für den die Zellwolle bestimmt ist.Treatment with the highly masculine alkyl ethers of oxalkylamines or their salts give the rayon a high softness at the same time, which in in many cases is not desirable to this extent. It may therefore be necessary, to add additives to the treatment baths, which maintain the softness of the treated Press down a bit of rayon, in particular by adding small amounts of Proteins, carbohydrates, soaps, fatty sulfonic acid compounds and the like. Reach bodies with ease. These additives are determined by the intended use, for which the rayon is intended.
