Description

VERWENDUNG EINER CELLULOSISCHEN STAPELFASER DER GATTUNG LYOCELL ALS FÜLLFASER USE OF A CELLULOSIC STAPLE FIBER OF THE LYOCELL GENERAL AS FILLING FIBER
Die vorliegende Erfindung betrifft eine Verwendung einer cellulosischen Stapelfaser der Gattung Lyocell sowie von textilen Mischungen enthaltend diese Faser.The present invention relates to the use of a cellulosic staple fiber of the Lyocell genus and of textile mixtures containing this fiber.
Als Alternative zum Viskoseverfahren wurden in den letzten Jahren eine Reihe von Verfahren beschrieben, bei denen Cellulose ohne Bildung eines Derivats in einem organischen Lösungsmittel, einer Kombination eines organischen Lösungsmittels mit einem anorganischen Salz oder in wäßriger Salzlösung gelöst wird.As an alternative to the viscose process, a number of processes have been described in recent years in which cellulose is dissolved in an organic solvent, a combination of an organic solvent with an inorganic salt or in aqueous salt solution without the formation of a derivative.
Bis heute hat sich jedoch nur ein einziges Verfahren zur Herstellung solcher Formkörper bis zur industriellen Realisierung durchgesetzt. Bei diesem Verfahren wird als Lösungsmittel ein tertiäres Aminoxid, insbesondere N-Methylmorpholin-N-oxid (NMMO), verwendet. Das Verfahren zur Herstellung von Formkörpern aus einer Lösung der Cellulose in einem wässerigen tertiären Aminoxid wird als „Ammoxidverfahren" oder „Lyocellverfahren" bezeichnet.To date, however, only a single process for the production of such molded articles has become established until industrial implementation. In this process, a tertiary amine oxide, in particular N-methylmorpholine-N-oxide (NMMO), is used as the solvent. The process for the production of moldings from a solution of cellulose in an aqueous tertiary amine oxide is referred to as the “ammoxide process” or “lyocell process”.
Die Lösung der Cellulose wird in diesem Verfahren üblicherweise mittels eines Formwerkzeuges extrudiert und dabei ausgeformt. Die ausgeformte Lösung gelangt über einen Luftspalt in ein Fällbad, wo durch Ausfällen der Lösung der Formkörper erhalten wird. Der Formkörper wird gewaschen und ggf. nach weiteren Behandlungsschritten getrocknet.In this process, the solution of the cellulose is usually extruded using a molding tool and shaped in the process. The formed solution passes through an air gap into a precipitation bath, where the shaped body is obtained by precipitation of the solution. The molded body is washed and, if necessary, dried after further treatment steps.
Cellulosefasern, die aus solchen Lösungen hergestellt werden, heißen „lösungsmittelgesponnene" Fasern und erhielten von der BISFA (The International Bureau for the Standardisation of Man Made Fibres) den Gattungsnamen Lyocell. Ein Verfahren zur Herstellung von Lyocellfasern ist z.B. in der US-A 4,246,221 beschrieben. Das Aminoxidverfahren liefert Fasern, die sich durch eine hohe Festigkeit, einen hohen Naßmodul und durch eine hohe Schiingenfestigkeit auszeichnen.Cellulose fibers which are produced from such solutions are called “solvent-spun” fibers and have been given the generic name Lyocell by the BISFA (The International Bureau for the Standardization of Man Made Fibers). A method for producing lyocell fibers is described, for example, in US Pat. No. 4,246,221 The amine oxide process provides fibers which are characterized by high strength, high wet modulus and high loop strength.
Lyocellfasern werden hauptsächlich in Form von geschnittenen Fasern mit diskreter Länge, d.h. als sogenannte „Stapelfasern" eingesetzt. Wenn im folgenden von „Lyocellfasern" die Rede ist, so sind Lyocellfasern in Form von Stapelfasern gemeint.Lyocell fibers are mainly in the form of cut fibers of discrete length, i.e. used as so-called "staple fibers". When "lyocell fibers" are referred to below, lyocell fibers in the form of staple fibers are meant.
Es ist bekannt, Lyocellfasern als Füllfasern, z.B. in Form von Vliesen in Steppdecken und als Bällchen in Kissen einzusetzen. Der Vorteil der Lyocellfasern in dieser Anwendung liegt im Vergleich zu anderen Fasertypen, wie zB. Polyesterfasern in den hervorragenden physiologischen Merkmalen. Als Nachteil muß die, gegenüber Polyester-Fasern, geringere Bauschelastizität und Waschbeständigkeit angeführt werden. Um ein Optimum an Physiologie und Gebrauchstüchtigkeit zu bekommen, werden textile Mischungen aus Lyocell- und Polyesterfasern vorgeschlagen. Solche Mischungen werden z.B. in der EP-A 0 941 209 beschrieben.It is known to use lyocell fibers as filling fibers, for example in the form of nonwovens in quilts and as balls in pillows. The advantage of Lyocell fibers in this application is compared to other types of fibers, such as. Polyester fibers in the excellent physiological characteristics. As a disadvantage, the lower compared to polyester fibers Structural elasticity and wash resistance can be mentioned. Textile blends of Lyocell and polyester fibers are suggested to get the best in physiology and fitness for use. Such mixtures are described, for example, in EP-A 0 941 209.
Als weitere Mischungspartner für Lyocellfasern werden aber auch Daunen und Federn, z.B. für Kasettendecken herangezogen. Diese Mischungen können sowohl trocken als auch naß hergestellt werden.Down and feathers, e.g., are also used as additional blending partners for Lyocell fibers. used for coffered ceilings. These mixtures can be made both dry and wet.
Dabei hat sich herausgestellt, dass Fasern mit niedrigeren Titern und größeren Schnittlängen zu inhomogenen Mischungen neigen und eine Tendenz zu Verknäuelungen haben, wodurch sie für diese Anwendung schlecht geeignet sind.It has been found that fibers with lower titers and longer cut lengths tend to inhomogeneous mixtures and have a tendency to tangle, making them poorly suited for this application.
Die vorliegende Erfindung stellt sich zur Aufgabe eine Stapelfaser der Gattung Lyocell zur Verfügung zu stellen, welche besser als bisher bekannte Lyocell-Fasertypen als Füllfaser sowie als Mischungspartner für textile Mischungen mit anderen Fasertypen oder Daunen bzw. Federn geeignet sind.The present invention has for its object to provide a staple fiber of the Lyocell genus, which are better than previously known Lyocell fiber types as filler fibers and as a blend partner for textile blends with other fiber types or down or feathers.
Diese Aufgabe wird dadurch gelöst, daß man eine cellulosische Stapelfaser der Gattung Lyocell mit einer Wertzahl des Verhältnisses von Titer (in dtex) zu Schnittlänge (in mm) von 0,10 oder mehr als Füllfaser für Decken, Polster, Kissen, Matratzen oder Vliese für Polstermöbel verwendet.This object is achieved in that a cellulosic staple fiber of the Lyocell genus with a value of the ratio of titer (in dtex) to cutting length (in mm) of 0.10 or more as filler for blankets, cushions, pillows, mattresses or nonwovens for Upholstered furniture used.
Überraschenderweise hat sich herausgestellt, dass Lyocellfasern mit einer im Verhältnis zu bekannten Fasertypen höheren Wertzahl des Verhältnisses von Titer zu Schnittlänge eine geringere Verknäuelungstendenz zeigen und z.B. sehr homogene Mischungen mit Daunen ergeben.Surprisingly, it has been found that lyocell fibers with a higher value number in relation to known fiber types in the ratio of titer to cutting length have a lower tendency to curl and e.g. result in very homogeneous blends with down.
Mit abnehmendem Titer und zunehmender Schnittlänge verstärkt sich hingegen die Verknäuelungs- und Homogenitätsproblematik. Als hervorragender Fasertyp, insbesondere für Mischungen mit Daunen haben sich Lyocellfasern herausgestellt, bei denen die Wertzahl des Verhältnisses von Titer zu Schnittlänge 0,5 bis 5 beträgt.With decreasing titer and increasing cutting length, on the other hand, the tangling and homogeneity problems increase. Lyocell fibers, in which the value of the ratio of titer to cutting length is 0.5 to 5, have proven to be an excellent type of fiber, especially for blends with down.
Bevorzugt beträgt der Titer der erfindungsgemäß verwendeten Faser 1,3 bis 3,3 dtex, besonders bevorzugt 1,3 bis 1,7 dtex. In einer besonders bevorzugten Ausführungsform weist die erfindungsgemäß verwendete Faser einen Titer von 6,7 dtex und eine Schnittlänge von 6 mm auf.The titer of the fiber used according to the invention is preferably 1.3 to 3.3 dtex, particularly preferably 1.3 to 1.7 dtex. In a particularly preferred embodiment, the fiber used according to the invention has a titer of 6.7 dtex and a cutting length of 6 mm.
Aus verarbeitungstechnischen Gründen sollte die Schnittlä ge nicht unter 3 mm liegen. Für die Verwendung der Faser in Faserbällchen haben sich Schnittlängen von 22-30 mm als günstig erwiesen, für die Verwendung in Vliesen sind Schnittlängen bis zu 60 mm geeignet.For processing reasons, the cut should not be less than 3 mm. Cutting lengths of 22-30 mm have proven to be favorable for the use of the fiber in fiber balls, cutting lengths of up to 60 mm are suitable for the use in nonwovens.
Die erfindungsgemäß verwendete Faser liegt bevorzugt in silikonisierter Form vor.The fiber used according to the invention is preferably in siliconized form.
In einer bevorzugten Ausführungsform wird die oben definierte Faser der Gattung Lyocell in Mischung mit zumindest einer Faser einer anderen Fasergattung und/oder Daunen und Federn eingesetzt.In a preferred embodiment, the fiber of the Lyocell type defined above is used in a mixture with at least one fiber of another fiber type and / or down and feathers.
Die textile Mischung kann z.B. in Form eines Vlieses oder eines Bällchens vorliegen.The textile mixture can e.g. in the form of a fleece or a ball.
Wird als Mischungspartner eine andere Faser eingesetzt, so ist diese bevorzugt aus der Gruppe der synthetischen Fasern, besonders bevorzugt aus der Gruppe bestehend aus Polyesterfasern, Polyamidfasern, Polypropylenfasern und Polylactatfasern ausgewählt.If another fiber is used as the mixing partner, it is preferably selected from the group of synthetic fibers, particularly preferably from the group consisting of polyester fibers, polyamide fibers, polypropylene fibers and polylactate fibers.
Der Anteil an Lyocell-Faser wie oben definiert in der Mischung beträgt bevorzugt von 30 bis 50 Gew.%.The proportion of Lyocell fiber as defined above in the mixture is preferably from 30 to 50% by weight.
Ein weiterer Aspekt der vorliegenden Erfindung eine Decke, einen Polster, ein Kissen, eine Matratze oder ein Vlies für Polste möbel, enthaltend eine Stapelfaser der Gattung Lyocell oben definiert definiert und/oder eine Mischung wie oben definiert als Füllfaser.Another aspect of the present invention is a blanket, a cushion, a pillow, a mattress or a fleece for upholstery furniture, comprising a staple fiber of the Lyocell genus defined above and / or a mixture as defined above as filler fiber.
Es hat sich gezeigt, daß sich die Lyocellfasern mit bestimmten Nerhältnis zwischen Titer und Schnittlänge bzw. textile Mischungen, welche diese Faser enthalten, hervorragend für den Einsatz als Füllfaser eignen. It has been shown that the lyocell fibers with a certain ratio between titer and cutting length or textile mixtures which contain this fiber are outstandingly suitable for use as filler fibers.
