Description

Für viele Einsatzzwecke ist es notwendig, den Quellwert von Fasern aus regenerierter Cellulose möglichst gering zu machen. Dies erhöht die Gebrauchstüchtigkeit des Materials. Man hat hierfür die verschiedensten Verfahren angewendet und dabei versucht, sowohl die Eigenschaften der Fasern beim Spinnprozeß oder in einer anschließenden Nachbehandlung zu beeinflussen.For many purposes it is necessary to use the swelling value of fibers made from regenerated cellulose to make it as low as possible. This increases the usability of the material. You have to do this applied various methods and tried to both the properties of the fibers when To influence the spinning process or in a subsequent aftertreatment.

Unter anderem ist ein Verfahren bekanntgeworden, nach welchem das Wasseraufnahmevermögen von Fasern aus regenerierter Cellulose dadurch herabgesetzt wird, daß man die fertigen Produkte in Gegenwart von Feuchtigkeit der Einwirkung von gasförmigem Ammoniak oder Hydrazinhydratdampf aussetzt. Diese Behandlung erfolgt bei Temperaturen zwischen -20 und +20° CAmong other things, a method has become known, according to which the water absorption capacity of Regenerated cellulose fibers are reduced by having the finished products in the presence exposure to gaseous ammonia or hydrazine hydrate vapor. This treatment takes place at temperatures between -20 and + 20 ° C

Darüber hinaus ist auch bekannt, daß sich native Cellulose durch Behandlung mit flüssigem Ammoniak in eine andere Modifikation überführen läßt. Es tritt bei dieser Behandlung eine röntgenographisch meßbare Gitterverengung ein.In addition, it is also known that native cellulose can be removed by treatment with liquid ammonia can be converted into another modification. With this treatment, a radiographically measurable effect occurs Lattice narrowing on.

Es wurde nun gefunden, daß man die Gebrauchstüchtigkeit von Hydratfasern durch Senkung des Quellwertes und gleichzeitige Steigerung der Kräuselbogenzahl und -beständigkeit dadurch verbessern kann, daß man die Hydratfaser kurzzeitig der Einwirkung von flüssigem Ammoniak bei etwa — 60° C aussetzt und anschließend mit kaltem Wasser auswäscht. Gegenüber dem bereits bekannten langwierigen Behandlungsverfahren von Fasern oder Geweben mit gasförmigem Ammoniak oder Aminen wird durch die nur wenige Minuten dauernde Behandlung mit flüssigem Ammoniak der wesentliche Vorteil erreicht, daß eine gleichmäßige Erfassung aller Fasern ermöglicht wird, die entgegen einer Einwirkung von gasförmigen Produkten auch einen gleichmäßigen Ausfall in der Unifärbung gewährleistet. Über die bereits genannten Verbesserungen hinaus bringt diese Behandlung außerdem Verbesserungen hinsichtlich der Naßfestigkeit und Schiingenfestigkeit mit sich. Das Auswaschen mit kaltem Wasser ist notwendig, weil die Hydratfasern, die bei der Behandlung mit flüssigem Ammoniak stark aufquellen, zu Verklebungen neigen. Durch das Eintragen der Fasern in kaltes Wasser unmittelbar nach der Behandlung mit flüssigem Ammoniak gelingt es jedoch, diese Verklebungen zu vermeiden und Fasern zu erhalten, die die obengenannten günstigen Eigenschaften aufweisen und in gut verarbeitbarem Zustand vorliegen.It has now been found that the serviceability of hydrate fibers by lowering the Improve the swelling value and at the same time increase the number and resistance of the curled sheets can that the hydrate fiber is briefly exposed to the action of liquid ammonia at about - 60 ° C exposed and then washed out with cold water. Compared to the already known lengthy one Treatment process of fibers or fabrics with gaseous ammonia or amines is carried out by the Only a few minutes of treatment with liquid ammonia achieves the essential advantage that a uniform detection of all fibers is made possible, which is contrary to the action of gaseous Products are also guaranteed to have a uniform appearance in the unicoloured color. About those already mentioned In addition to improvements, this treatment also brings about improvements in wet strength and loop strength with it. Washing with cold water is necessary because the hydrate fibers, which swell strongly when treated with liquid ammonia and tend to stick together. By immersing the fibers in cold water immediately after treatment with liquid ammonia However, it is possible to avoid these adhesions and to obtain fibers which are favorable to those mentioned above Have properties and are in a readily processable condition.

Der Querschnitt der auf diese Weise nachbehandelten Faser unterscheidet sich durch eine starke Lappung von unbehandelten Fasern.The cross-section of the fiber post-treated in this way differs in its strong lapping of untreated fibers.

Kräuselbeständigkeit werden durch die erfindungsgemäße Behandlungsmethode weder die Faserfestigkeit noch die Dehnung ungünstig beeinflußt. Die Schiingenfestigkeiten, die als besonderes Merkmal für die Gebrauchstüchtigkeit von Fasern angesehen werden, lassen sich sogar bis auf den doppelten Wert steigern. Das Verfahren ist nicht auf eine Behandlung der Fasern beschränkt, sondern läßt sich auch an Geweben aus Cellulosehydratfasern durchführen. Gewebe zeigen nach dieser Behandlung eine höhere Bauschigkeit.By the treatment method according to the invention, neither the fiber strength nor the curl resistance become nor the elongation adversely affected. The loop strength, which is a special characteristic for The serviceability of fibers can even be viewed up to twice the value increase. The method is not limited to a treatment of the fibers, but can also be used Perform fabrics made from hydrate cellulose fibers. Tissues show a higher level after this treatment Bulkiness.

BeispiellFor example

Eine mattierte Faser mit einem Einzeltiter von 3,7 den und einer Stapellänge von 120 mm wird 6 Minuten in flüssiges Ammoniak von etwa — 60iO C eingetaucht und danach in kaltem Wasser ausgewaschen und getrocknet. Während der Ausgangsquellwert 98,3% betrug, liegt der Quellwert der behandelten Faser bei 65,8%. Die Trockenfestigkeit von 2,6 g/den bleibt unverändert, während die Naßfestigkeit von 1,3 g/den auf 1,5 g/den ansteigt, das entspricht einem Anstieg der relativen Naßfestigkeiten von 55 auf 63%. Die Trockendehnungen erhöhen sich von 16 auf 23% und die Naßdehnungen von 22 auf 31%. Die Schiingenfestigkeiten steigerten sich auf das Doppelte. Die Kräuselbogenzahl wurde von 73 Bögen/100 mm auf 110 Bögen/100 mm erhöht, und die Kräuselbeständigkeit stieg von 44 auf 53%. Eine Beeinträchtigung des Durchschnittspolymerisationsgrades tritt nicht ein.A matt fiber with a single titer of 3.7 denier and a staple length of 120 mm is immersed in liquid ammonia at about -60 ° C. for 6 minutes and then washed in cold water and dried. While the initial swell value was 98.3%, the swell value of the treated fiber is 65.8%. The dry strength of 2.6 g / den remains unchanged, while the wet strength increases from 1.3 g / den to 1.5 g / den, which corresponds to an increase in the relative wet strengths from 55 to 63%. The dry elongations increase from 16 to 23% and the wet elongations from 22 to 31%. The loop strength doubled. The number of curling sheets was increased from 73 sheets / 100 mm to 110 sheets / 100 mm, and the curling resistance was increased from 44 to 53%. The average degree of polymerisation is not impaired.
