Description

Die Erfindung betrifft ein Verfahren zur Herstellung von cellulosischen Formkörpern mit verbesserter funktionaler Wirkung speziell für den Einsatz in der Medizin, Hygiene und Bekleidung. Die funktionale Wirkung bezieht sich dabei auf eine gleichmäßige und feindosierbare bakterizide Wirkung von beispielsweise wundreinigenden Auflagen, TextilienThe The invention relates to a process for the production of cellulosic moldings with improved functional effect especially for use in medicine, Hygiene and clothing. The functional effect refers to it on a uniform and Feindosierbare bactericidal action of, for example, wound-cleaning Editions, textiles

[Stand der Technik][State of the art]

Es ist bekannt, dass Schwermetallionen wie z. B. Silber-, Quecksilber-, Kupfer- und Zinkionen auf Mikroorganismen wie Bakterien, Viren, Pilze und Sporen abtötend oder wachstumshemmend wirken. Für eine bakterizide Wirkung sind die der Silberionen von besonderem Interesse. Der entscheidende Vorteil von Silberionen gegenüber anderen bakterizid wirkenden Metallionen, wie z. B. Hg2+, ist die weitestgehende Unempfindlichkeit des menschlichen Metabolismus gegenüber Silber. Die bakterizid wirkende Konzentration wird bei Silber mit 0,01–1 mg/l angegeben.It is known that heavy metal ions such. As silver, mercury, copper and zinc ions on microorganisms such as bacteria, viruses, fungi and spores kill or inhibit growth. For a bactericidal effect, those of the silver ions are of particular interest. The decisive advantage of silver ions over other bactericidal metal ions, such. B. Hg 2+ , is the most insensitive human metabolism to silver. The bactericidal concentration is given as 0.01-1 mg / l in silver.

Diese Wirkung der Silberionen wird seit langem in den unterschiedlichsten Anwendungen genutzt. Bei der Herstellung von textilen Fasern wird Silber z. B. galvanisch auf der Oberfläche abgelagert. Eine weitere bekannte Möglichkeit ist das Einbringen von metallischem Silber, Silber-Zeolith oder Silberglaskeramik in die Fasermatrix. Die genannten Verfahren basieren auf der Freisetzung von Silberionen über die Oxidation von Silber zu Silberoxid. In wässrigen Lösungen bilden sich Silberionen.This Effect of silver ions has long been in the most diverse Applications used. In the production of textile fibers is Silver z. B. deposited galvanically on the surface. Another known possibility is the introduction of metallic silver, silver zeolite or Silver glass ceramic in the fiber matrix. The mentioned methods are based on the release of silver ions via the oxidation of silver to silver oxide. In aqueous solutions Silver ions form.

Eine weitere Möglichkeit ist die Einarbeitung von Algen in eine cellulosische Matrix, wie sie in der WO 01/62844 A1 beschrieben ist. Algen zeigen ein Sorptionsverhalten gegenüber von Metallionen. Bei diesem Sorptionsverhalten spielen unterschiedliche Bindungsmechanismen eine Rolle, die zum Teil nicht geklärt sind. Da Algen Naturprodukte sind, schwanken die relativ begrenzten Sorptionskapazitäten, die Sorptionsprozesse sind nicht exakt reproduzierbar, die Selektivitäten sind nicht einstellbar. Des weiteren können nur Kationen und keine Anionen gebunden werden.A another possibility is the incorporation of algae into a cellulosic matrix, like it is described in WO 01/62844 A1. Algae show a sorption behavior across from of metal ions. In this sorption behave different binding mechanisms a role that is partly unclear. Because algae are natural products are fluctuate, the relatively limited sorption capacity, the sorption are not exactly reproducible, the selectivities are not adjustable. Furthermore, you can only cations and no anions are bound.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von cellulosischen Formkörpern mit funktionaler Wirkung für den Einsatz in der Medizin, Hygiene und Bekleidung zu entwickeln, die beispielsweise eine bakterizide Wirkung mit den Vorteilen eines atmungsaktiven Kleidungsstückes verbindet. Eine weitere Aufgabe besteht darin, die Wirkstoffe in einem textilen Depot vorzuhalten und für eine ausreichende Abgabe dieser Stoffe aus dem Depot über die Zeit zu sorgen. Die abzugebende Wirkstoffkonzentration soll regelbar sein. Des weiteren sollen die nach dem erfindungsgemäßen Verfahren hergestellten Formkörper, insbesondere Fasern und Folien, so geschaffen werden, dass sie aufgrund ihres hohen Adsorptionsvermögens an Wirkstoffen zur Herstellung als Wundauflagen, Pflaster, Hygieneartikel, Spezialpapiere und als Verpackungsmaterial geeignet sind. Schließlich sollen Verbundstoffe aus Mischungen mit anderen Faserstoffen herstellbar werden.Of the Invention is based on the object, a process for the preparation of cellulosic shaped bodies with functional effect for to develop the use in medicine, hygiene and clothing, for example, a bactericidal effect with the advantages of breathable garment combines. Another task is to use the active ingredients in keep a textile depot and for a sufficient levy these substances from the depot over the time to worry. The drug concentration to be delivered should be controllable. Furthermore, according to the inventive method molded body, In particular, fibers and films are created so that they are suitable for their use high adsorption capacity to active substances for the production as wound dressings, patches, hygiene articles, Special papers and as packaging material are suitable. Finally, should Composites of mixtures with other fibers can be produced.

Die Lösung dieser Aufgabe ist ein Verfahren bei dem cellulosische Formkörper mit hohem Adsorptionsvermögen, wie sie nach dem Trocken-Naßextrusionsverfahren aus beispielsweise der DE 199 17 614 C2 bekannt ist (Ionentauscherfasern), mit Wirkstoffen beladen werden, die ein Wirkstoffdepot derart auf der Faser oder Folie aufbauen, welches in der Lage ist diese Wirkstoffe entsprechend ihrer Gleichgewichtskonzentration über die Zeit wieder abgegeben zu können. Die Gleichgewichtskonzentration ist über das Verhältnis der tatsächlichen Beladung zur Gesamtkapazität regelbar. Die Adsorptionskapazität ist abhängig von der Art und Menge des inkorporierten Ionentauschers.The solution to this problem is a method in the cellulosic moldings with high adsorptive capacity, as after the dry Naßextrusionsverfahren from, for example, the DE 199 17 614 C2 is known (ion exchange fibers) are loaded with drugs that build a drug depot so on the fiber or film, which is able to deliver these drugs according to their equilibrium concentration over time again. The equilibrium concentration can be regulated by the ratio of the actual load to the total capacity. The adsorption capacity is dependent on the type and amount of the incorporated ion exchanger.

Die mit Wirkstoff beladenen Fasern kann man mit unbeladenen Ionentauscherfasern mischen, um die Gleichgewichtskonzentration zu niedrigeren Konzentrationen zu steuern. Die mit Wirkstoff beladene Ionentauscherfasern können auch mit textilen Fasern, wie Polyethylenfasern, Polyesterfasern, Polyamidfasern, Polyac rylfasern und cellulosischen Fasern gemischt werden, um diese Fasermischungen zu textilen Flächengebilden zu verarbeiten.The With active ingredient loaded fibers can be used with unloaded ion exchange fibers mix the equilibrium concentration to lower concentrations to control. The loaded with active ion exchange fibers can also with textile fibers, such as polyethylene fibers, polyester fibers, polyamide fibers, Polyac rylfasern and cellulosic fibers are mixed to this Fiber blends to textile fabrics to process.

Die Konzentrationen der Metalle auf der Faser liegen zweckmäßigerweise zwischen 0,005 g Metall/kg Faser bis > 100 g Metall/kg Faser.The Concentrations of the metals on the fiber are suitably between 0.005 g metal / kg fiber to> 100 g metal / kg fiber.

Die Konzentrationen richten sich nach der jeweiligen medizinischen Anwendung. Die mit Wirkstoffen beladenen Fasern können auch zur Herstellung von Spezialpapieren einsetzt (z.B. Luftfilter für Krankenhäuser; medizinische Papiere).The Concentrations depend on the particular medical application. The loaded with active ingredients fibers can also be used for the production of Special papers (e.g., air filters for hospitals, medical papers).
