Description

Verfahren zur Behandlung von cellulosischen FormkörpernProcess for the treatment of cellulosic moldings
Die Erfindung betrifft ein Nerfahren zur Behandlung von cellulosischen Formkörpern, die aus einer Lösung der Cellulose in einem wäßrigen tertiären Aminoxid hergestellt werden, insbesondere Fasern und Gebilde, welche diese Fasern enthalten, bei welchem Nerfahren die Foirnkörper mit einem Textilhilfsmittel in Kontakt gebracht werden, um den Formkörpern verbesserte Eigenschaften zu verleihen.The invention relates to a ner process for the treatment of cellulosic molded articles which are produced from a solution of the cellulose in an aqueous tertiary amine oxide, in particular fibers and structures which contain these fibers, in which ner process the foam articles are brought into contact with a textile auxiliary in order to To give moldings improved properties.
Für die Zweck der vorliegenden Erfindung umfaßt der Begriff „Formkörper" insbesondere auch Schwämme.For the purpose of the present invention, the term “molded body” in particular also includes sponges.
Als Alternative zum Niskoseverfahren wurden in den letzten Jahren eine Reihe von Nerfahren 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. Cellulosefasem, 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. Als Lyocell wird von der BISFA eine Cellulosefaser definiert, die durch ein Spinnverfahren aus einem organischen Lösungsmittel erhalten wird. Unter „organisches Lösungsmittel" wird von der BISFA ein Gemisch aus einer organischen Chemikalie und Wasser verstanden. „Lösungsmittelspinnen" soll Auflösen und Spinnen ohne Derivatisierung bedeuten.As an alternative to the anesthetic process, a number of ner 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. Cellulose fibers that 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) an organic solvent is obtained. BISFA understands “organic solvent” as a mixture of an organic chemical and water. "Solvent spinning" is intended to mean dissolving and spinning without derivatization.
Bis heute hat sich jedoch nur ein einziges Nerfahren zur Herstellung einer lösungsmittelgesponnenen Cellulosefaser bis zur industriellen Realisierung durchgesetzt. Bei diesem Nerfahren wird als Lösungsmittel ein tertiäres Aminoxid, insbesondere Ν- Methylmorpholin-Ν-oxid (ΝMMO), verwendet. Ein solches Nerfahren ist z.B. in der US-A 4,246,221 beschrieben und liefert Fasern, die sich durch eine hohe Festigkeit, einen hohen Νaßmodul und durch eine hohe Schiingenfestigkeit auszeichnen.To date, however, only a single ner process for producing a solvent-spun cellulose fiber has prevailed until industrial implementation. In this process, a tertiary amine oxide, in particular Ν-methylmorpholine-Ν-oxide (ΝMMO), is used as the solvent. Such a ner driving is e.g. described in US Pat. No. 4,246,221 and delivers fibers which are distinguished by high strength, a high modulus of elasticity and by a high loop strength.
Die WO 99/19555 beschreibt ein Nerfahren zur Behandlung lösungsmittelgesponnener . Fasern, bei welchem die Fasern mit 2,4-dichlor-6-hydroxy-1.3.5-triazin bzw. mit einem Salz davon in Kontakt gebracht werden. Die so hergestellten Fasern zeichnen sich durch eine bessere Beständigkeit gegenüber Fibrillation aus.WO 99/19555 describes a ner process for the treatment of solvent-spun. Fibers in which the fibers are brought into contact with 2,4-dichloro-6-hydroxy-1.3.5-triazine or with a salt thereof. The fibers produced in this way are characterized by better resistance to fibrillation.
Aus der US 5,728,823 sind Cyclodextrinderivate, unter anderem das Νatriumsalz des 2- chloro-4-hydroxy-1.3.5-triazinylcyclodextrins bekannt. Die US 5,728,823 beschreibt weiters Membranen, Folien, Textilien oder Leder, an welche ein Cyclodextrinderivat gebunden ist. Mit Cyclodextrinderivaten behandelte Textilien eignen sich z.B. zur Absorption unangenehmer Gerüche.No. 5,728,823 discloses cyclodextrin derivatives, including the sodium salt of 2-chloro-4-hydroxy-1.3.5-triazinylcyclodextrin. US 5,728,823 also describes Membranes, foils, textiles or leather to which a cyclodextrin derivative is bound. Textiles treated with cyclodextrin derivatives are suitable, for example, for absorbing unpleasant odors.
Die WO 01/48025 beschreibt Cyclodextrine, welche mittels eines Nernetzungsmittels kovalent an ein Polysaccharid gebunden sind.WO 01/48025 describes cyclodextrins which are covalently bound to a polysaccharide by means of a wetting agent.
Es wurde nun gefunden, daß man cellulosische Formkörper, die aus einer Lösung der Cellulose in einem wäßrigen tertiären Aminoxid hergestellt werden, mit einem Textilhilfsmittel, welches ein Cyclodextrin und/oder ein Cyclodextrinderivat umfaßt, behandeln kann, wodurch Produkte mit verbesserten Eigenschaften entstehen.It has now been found that cellulosic moldings which are prepared from a solution of the cellulose in an aqueous tertiary amine oxide can be treated with a textile auxiliary which comprises a cyclodextrin and / or a cyclodextrin derivative, thereby producing products with improved properties.
Bevorzugt handelt es sich bei den Formkörpern um Fasern in niemals getrocknetem Zustand. Die Fasern können in niemals getrocknetem Zustand in einer Νachbehandlungsstufe einer kontinuierlich arbeitenden Produktionsanlage behandelt werden.The shaped bodies are preferably fibers in a never-dried state. The fibers can be treated in a never-dried state in a post-treatment stage of a continuously operating production plant.
Es ist bekannt, daß Cyclodextrine Wirkstoffe einschließen können, die dann beispielsweise über einen längeren Zeitraum freigesetzt werden. Im erfindungsgemäßen Nerfahren ist es möglich, die im Zuge des kontinuierlichen Produktionsverfahrens mit einem Cyclodextrin bzw. einem Cyclodextrinderivat behandelte Faser gleichzeitig und/oder nachfolgend mit einem solchen Wirkstoff zu beladen.It is known that cyclodextrins can include active ingredients which are then released, for example, over a longer period of time. In the ner process according to the invention, it is possible to load the fiber treated with a cyclodextrin or a cyclodextrin derivative in the course of the continuous production process simultaneously and / or subsequently with such an active ingredient.
Die Behandlung mit dem Textilhilfsmittel erfolgt bevorzugt in alkalischem Milieu.The treatment with the textile auxiliary is preferably carried out in an alkaline environment.

Particularly preferred wetting agent is 2,4-dichloro-6-hydroxy-1,3,5-triazine or a salt thereof.
Im Stand der Technik gemäß US 5,728,823 muß zunächst aufwendig ein Cyclodextrinderivat, z.B. das Νatriumsalz des 2-chlor-4-hydroxy-1.3.5- triazinylcyclodextrins, hergestellt werden, um dieses Derivat anschließend auf das zu _ behandelnde Material aufzubringen.In the prior art according to US 5,728,823, a cyclodextrin derivative, e.g. the sodium salt of 2-chloro-4-hydroxy-1.3.5-triazinylcyclodextrin, are prepared in order to subsequently apply this derivative to the material to be treated.
Es hat sich nun gezeigt, daß man den zu behandelnden Fasern das Cyclodextrin und ein Nemetzungsmittel, insbesondere das 2,4-dichlor-6-hydroxy-1.3.5-triazin, ohne zuvor eine Nerbindung aus diesen beiden Substanzen herstellen zu müssen, zugeben kann und zu guten Resultaten gelangt. In einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens umfaßt das Textilhilfsmittel 2-chlor-4-hydroxy-1.3.5-triazinyl-cyclodextrin (MCT-CD) bzw. ein Salz davon.It has now been found that the fibers to be treated can be added with the cyclodextrin and a wetting agent, in particular 2,4-dichloro-6-hydroxy-1.3.5-triazine, without having to prepare a nerbinding from these two substances beforehand and get good results. In a further embodiment of the process according to the invention, the textile auxiliary comprises 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin (MCT-CD) or a salt thereof.
