Abstract
Description
Die vorliegende Erfindung betrifft Distanzfäden enthaltende bioabbaubare Textilprodukte, die sich insbesondere als Matratzen oder als Polsterformkörper einsetzen lassen.The present invention relates to spacer threads containing biodegradable textile products, which can be used in particular as mattresses or as pad moldings.
Textilprodukte aus beabstandeten textilen Flächen sind an sich bekannt. Diese werden auch als Abstandsgewirke bezeichnet. Sie bestehen im Wesentlichen aus zwei textilen Flächen, die über Distanzfäden, die den Abstand dieser beiden Flächen im unbelasteten Zustand konstant halten, miteinander verbunden sind. Als Distanzfäden können beliebige Fäden eingesetzt werden, beispielsweise Monofilamente oder Multifilamente. Die Steifheit von Abstandsgewirken kann z.B. durch die Art und Anzahl der Distanzfäden variiert werden. Verwendet man Mono- statt Multilamente als Fäden, so wird wegen deren Steifheit das Abstandsgewirke stabiler. Das Gleiche gilt, wenn die Zahl der Fäden pro Flächeneinheit, die den Abstand definieren, erhöht wird. Zum Komprimieren des Abstandes der beiden das Gewirke begrenzenden Flächen sind dann höhere Kräfte aufzuwenden, bzw. das Abstandsgewirke hält höheren Kräften stand.Textile products from spaced textile surfaces are known per se. These are also called spacer knitted fabrics. They consist essentially of two textile surfaces which are connected to one another via spacer threads, which keep the distance of these two surfaces constant in the unloaded state. As spacer threads, any threads can be used, for example monofilaments or multifilaments. The stiffness of spacer fabrics can be e.g. be varied by the type and number of spacer threads. If mono- instead of multi-filaments are used as threads, the spacer fabric becomes more stable because of their stiffness. The same applies if the number of threads per unit area defining the distance is increased. To compress the distance of the two areas bounding the fabric then higher forces are expended, or the spacer knitted fabric withstands higher forces.

Eine der bevorzugten Anwendungen derartiger Textilprodukte ist die Verwendung als Komponente in Verbundkonstruktionen von Matratzen oder Polstermöbeln.One of the preferred applications of such textile products is the use as a component in composite constructions of mattresses or upholstered furniture.
Derartige, für die Anwendung in Matratzen besonders geeignete Textilprodukte werden in den
Auch lassen sich durch mehrere Lagen komplette Matratzen und Polster herstellen, wie dies z.B. in der
Neben der leichten Komprimierbarkeit und dem Wiederauftrichtevermögen ist einer der entscheidenden Vorteile dieser Textilprodukte die gute Hinterlüftung der Liege- bzw. Sitzfläche, mit der z.B. der durch Schweiß gebildete Dampf abtransportiert werden kann und somit der Sitz- bzw. Liegekomfort erhöht wird. Auch bei Kranken ist die Gefahr des Wundliegens damit erheblich herabgesetzt.In addition to the ease of compressibility and the ability to repulp, one of the decisive advantages of these textile products is the good ventilation of the lying or seating surface, with which e.g. The steam formed by sweat can be removed and thus the sitting or lying comfort is increased. Even with patients, the risk of bedsores is thus significantly reduced.
Matratzen und Polstermöbel sind ein bevorzugter Lebensraum für Kleinlebewesen, wie Hausstaubmilben. Aus hygienischen Gründen müssen Matratzen oder Polstermöbel deshalb häufiger gereinigt und je nach Belastung nach etwa fünf bis zehn Jahren ausgetauscht werden. Wegen ihres Volumens und der häufig verwendeten Gemischtbauweise ist die Entsorgung von Matratzen und Polstern problematisch. In der Regel müssen diese in einer Deponie oder in einer Müllverbrennungsanlage entsorgt werden. Recycling ist nur bei weitgehend sortenreinen Produkten möglich, z.B. bei Schaumstoffmatratzen oder solchen, die zu 100 % aus sortenreinen Abstandsgewirken aufgebaut sind. Da eine entsprechende Kennzeichnung und derzeit auch noch die gesetzlichen Grundlagen fehlen, werden diese Produkte heute in der Regel als Siedlungsabfall oder als Sperrmüll entsorgt.Mattresses and upholstered furniture are a preferred habitat for microorganisms, such as house dust mites. For reasons of hygiene, mattresses or upholstered furniture must therefore be cleaned more frequently and replaced after about five to ten years, depending on the load. Due to their volume and the commonly used mixed construction, the disposal of mattresses and upholstery is problematic. As a rule, these must be disposed of in a landfill or in a waste incineration plant. Recycling is only possible with largely single-variety products, for example in foam mattresses or those that are built up to 100% from unmixed distance knitted fabrics. Since there is no corresponding labeling and currently also the legal basis, these products are usually disposed of as municipal waste or bulky waste today.
Aufgabe der vorliegenden Erfindung ist die Bereitstellung von Textilprodukten, die sich zur Herstellung von Matratzen oder Polsterkörper eignen, und die nach dem Gebrauch umweltfreundlich entsorgt werden können.Object of the present invention is to provide textile products that are suitable for the production of mattresses or upholstery, and can be disposed of environmentally friendly after use.
Es wurde nun überraschend gefunden, dass Textilprodukte enthaltend Fäden aus ausgewählten Polymeren sich für diese Zwecke ausgezeichnet eignen.It has now surprisingly been found that textile products containing threads of selected polymers are excellently suitable for this purpose.
Die Erfindung betrifft ein Textilprodukt aus mindestens zwei beabstandeten textilen Flächen, die durch Distanzfäden miteinander verbunden sind, wobei zumindest die Distanzfäden zu mindestens 90 Gew. %, bezogen auf deren Gesamtmasse, aus einem oder mehreren aliphatischen Polyestern bestehen.The invention relates to a textile product of at least two spaced textile surfaces, which are connected by spacer threads, wherein at least the spacer threads to at least 90 wt.%, Based on the total mass, consist of one or more aliphatic polyesters.

Für den Aufbau können aber auch andere Fäden eingesetzt werden. Beim Aufbau aus Monofilamenten werden vorzugsweise zusätzlich Garne, wie Fasergarne oder Filamentgarne, eingebaut, um den textilen Charakter der Flächen zu verstärken. Die oberen und unteren textilen Flächen können aber auch ausschließlich aus Monofilamenten oder aus Garnen aufgebaut sein. Die Distanzfäden können ebenfalls aus Garnen sowie aus Zwirnen aufgebaut sein. Zur Erzeugung von Textilprodukten mit besonders hoher Steifigkeit setzt man bevorzugt Monofilamente als Distanzfäden ein.The limiting textile surfaces of the textile product according to the invention are constructed of threads. These are preferably monofilaments. For the structure but also other threads can be used. In the construction of monofilaments, yarns, such as fiber yarns or filament yarns, are preferably additionally incorporated in order to reinforce the textile character of the surfaces. The upper and lower textile surfaces can also be constructed exclusively from monofilaments or from yarns. The spacer threads can also be constructed of yarns and twines. To produce textile products with particularly high rigidity, monofilaments are preferably used as spacer threads.
Die Dichte der oberen und der unteren textile Fläche sowie die Dichte der Distanzfäden können über die Herstellungsweise des Textilproduktes beeinflusst werden.The density of the upper and lower textile surface as well as the density of the spacer threads can be influenced by the method of production of the textile product.
Die erfindungsgemäßen Textilprodukte weisen üblicherweise Abstände zwischen oberer und unterer textiler Fläche zwischen 5 und 100 mm auf. Größere und kleinere Abstände sind auch möglich.The textile products according to the invention usually have spacings between the upper and lower textile surface of between 5 and 100 mm. Larger and smaller distances are also possible.
Die Distanzfäden weisen typischerweise Titer im Bereich von 25 dtex bis 10000 dtex auf, vorzugsweise von 100 dtex bis 2500 dtex.The spacer yarns typically have titres in the range of from 25 dtex to 10,000 dtex, preferably from 100 dtex to 2500 dtex.

Der Begriff "aliphatischer Polyester" umfasst neben ausschließlich aus aliphatischen und/oder cycloaliphatischen Monomeren aufgebauten Polyestern auch solche Polyester, die neben aliphatischen und/oder cylcoaliphatischen Struktureinheiten geringe Anteile aromatischer Struktureinheiten, solange dadurch die Bioabbaubarkeit dieser Polyesters nicht nachteilig beeinträchtigt wird.The term "aliphatic polyester" in addition to exclusively composed of aliphatic and / or cycloaliphatic monomers polyesters also includes those polyesters, in addition to aliphatic and / or cylcoaliphatic structural units small proportions of aromatic structural units, as long as the biodegradability of these polyesters is not adversely affected.

Besonders bevorzugte Textilprodukte enthalten in den Distanzfäden und/oder in mindestens einer der textilen Flächen Biozide, vorzugsweise Kupfer- oder Silbersalze. Diese eingebauten Desinfektionsmittel gestatten einen Schutz vor Kleinlebewesen und Bakterien während des Gebrauchs.Particularly preferred textile products contain biocides, preferably copper or silver salts, in the spacer threads and / or in at least one of the textile surfaces. These built-in disinfectants allow protection against microbes and bacteria during use.
Die erfindungsgemäßen Textilprodukte zeichnen sich durch hervorragende biologische Abbaubarkeit aus.The textile products of the invention are characterized by excellent biodegradability.
Die Textilprodukte lassen sich in dem Fachmann bekannter Weise herstellen und in üblicher Weise zu Formkörpern verarbeiten. Beispiele für die Herstellung und Verarbeitung der Textilprodukte sind in den oben genannten Dokumenten zu finden.The textile products can be prepared in a manner known to the person skilled in the art and processed in the usual way to give moldings. Examples of the Production and processing of textile products can be found in the documents mentioned above.
Die aus den erfindungsgemäßen Textilprodukten hergestellten Formkörper können beliebige Gestalt aufweisen. Vorzugsweise eignen sich die erfindungsgemäßen Textilprodukte zur Herstellung von Matratzen oder Polsterkörpern.The molded articles produced from the textile products according to the invention can have any shape. The textile products according to the invention are preferably suitable for the production of mattresses or upholstered bodies.
Aus den erfindungsgemäßen Textilprodukten hergestellte Matratzen oder Polsterkörper lassen sich besonders gut reinigen; sie können sogar gewaschen werden und trocknen relativ schnell.Mattresses or upholstery bodies produced from the textile products according to the invention can be cleaned particularly well; they can even be washed and dry relatively quickly.
Wegen der guten Möglichkeiten zur Reinigung ist zudem die Lebensdauer gegenüber herkömmlichen Matratzen oder Polsterkörpern aus hygienischen Gründen höher.Because of the good cleaning options, the service life over conventional mattresses or upholstery is also higher for hygienic reasons.
Hervorzuheben ist der ausgezeichnet Liegekomfort durch gute Hinterlüftung und die damit verringerte Gefahren des Wundliegens.To emphasize is the excellent reclining comfort through good ventilation and the associated reduced risks of bed sores.
Besonders geeignet sind die erfindungsgemäßen Textilprodukte zur Herstellung von Matratzen, die in Krankenhäusern, Pflege- und Altenheimen eingesetzt werden.Particularly suitable are the textile products according to the invention for the production of mattresses, which are used in hospitals, nursing homes and retirement homes.
Nach der Ausmusterung sind diese Textilprodukte oder die Produkte enthaltend diese für die Entsorgung auf Deponien besonders geeignet.After the withdrawal, these textile products or the products containing them are particularly suitable for disposal on landfills.
Durch den Kontakt mit Bodenbakterien beginnt sofort ein biologischer Abbau des aliphatischen Polyesters. Bestehen nur die Distanzfäden des Textilproduktes aus aliphatischem Polyester, so zerfällt die dreidimensionale Konstruktion relativ rasch und die verbleibenden textilen Flächen können danach von Bodenbakterien effizient angegriffen werden. Bei sortenreinen Textilprodukten findet ein rascher und vollständiger Abbau statt.Through contact with soil bacteria, biodegradation of the aliphatic polyester begins immediately. If only the spacer threads of the textile product are made of aliphatic polyester, the three-dimensional construction decays relatively quickly and the remaining textile surfaces can decay then efficiently attacked by soil bacteria. For unmixed textile products, rapid and complete degradation takes place.
Damit sind diese Textilprodukte bzw. Produkte enthaltend diese besonders für Länder geeignet, in denen das Recycling oder die thermische Entsorgung noch nicht so weit fortgeschritten ist und/oder durch klimatische Gegebenheiten eingeschränkt ist, wie beispielsweise in Mittel- und Nordeuropa.Thus, these textile products or products containing these are particularly suitable for countries in which the recycling or thermal disposal is not so advanced and / or is limited by climatic conditions, such as in Central and Northern Europe.

Das nachfolgende Beispiel erläutert die Erfindung ohne diese zu begrenzen.The following example illustrates the invention without limiting it.
Auf einer Schmelzspinnanlage zur Herstellung von Monofilamenten wurde ein aliphatischer Polyester (Polymilchsäure, Nature Works Polylactide Resin 6400 D, Fa. Nature Works LLC, Minnetonka, USA) in Schnitzelform eingesetzt. Nach der Trockung des Rohstoffs wurde dieser extrudiert, über eine Spinnpumpe einem Spinnpack zugeführt, durch feine Bohrungen zu Monofilamenten versponnen, im Wasserbad abgeschreckt, anschließend unter Temperatureinwirkung dreistufig gestreckt, mit Präparation als Verarbeitungshilfsmittel versetzt und aufgespult.On a melt spinning plant for the production of monofilaments, an aliphatic polyester (polylactic acid, Nature Works Polylactide Resin 6400 D, Fa. Nature Works LLC, Minnetonka, USA) was used in Schnitzel form. After drying the raw material, this was extruded, fed via a spinning pump to a spin pack, spun through fine bores into monofilaments, quenched in a water bath, then stretched in three stages under the action of temperature, treated with preparation as a processing aid and wound.
Die erhaltenen Monofilamente wiesen folgende Fasereigenschaften auf:
