Abstract

The aim of the invention is to supplement the advantageous basic properties of the filling of bedspreads, pillows, cold protective clothing or upholstery for items of furniture for sitting or lying upon made of woven and non-woven fibers comprised of polylactic acid (PLA) with properties that are improved technologically as well as with regard to costs. To this end, the PLA is mixed together with a portion of the kapok fibers.

Description

Füllmaterial filling material
Die Erfindung betrifft ein Füllmaterial gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a filling material according to the preamble of the main claim.
Zur Füllung von Bettdecken, Kissen, K lteschutzbekleidung oder Pols- tern für Sitz- und Liegemobel ist es auch im Automobilbereich bekannt, Woven- und Non-Woven-Fasern aus Polymilchsaure PLA (PolyLactic Acid) zu verwenden, welche beispielsweise unter dem für die Firma Cargill Dow LLC, USA geschützten Marke Ingeo vertrieben werden. Solche Fasern aus PLA können aus jährlich nachwachsenden Rohstof- fen bestehen, sind vollständig biologisch abbaubar und weisen zudem hervorragende Eigenschaften zur Verwendung als Füllmaterial von Bettdecken, Kissen und Ähnlichem auf, da sie beispielsweise sehr luftig und elastisch sind, antiallergisch und auch ein Bakterienwachstum nicht unterstützten. Weiterhin ist es leicht zu verarbeiten und trägt ins- gesamt nachhaltig zum Schutz der Ressourcen bei.For the filling of duvets, pillows, cold protective clothing or upholstery for seating and reclining furniture, it is also known in the automotive sector to use woven and non-woven fibers made from polylactic acid PLA (PolyLactic Acid), which are used, for example, under the name of the company Cargill Dow LLC, U.S. trademark Ingeo. Such fibers made of PLA can consist of raw materials that grow annually, are completely biodegradable and also have excellent properties for use as filling material for duvets, pillows and the like, for example because they are very airy and elastic, anti-allergic and also do not support bacterial growth , Furthermore, it is easy to process and overall contributes to the protection of resources in a sustainable manner.
Aufgabe der Erfindung ist es, diesen vorteilhaften Grundeigenschaften weitere in technischer wie auch in wirtschaftlicher Hinsicht verbesserte Eigenschafen hinzuzufügen. Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Oberbegriffsmerkmalen erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebene technische Lehre dadurch, dass das Füllmaterial mit einem Anteil an Kapokfasern gemischt ist,The object of the invention is to add further properties which are improved both technically and economically to these advantageous basic properties. This object is achieved in conjunction with the preamble features according to the invention by the technical teaching specified in the characterizing part of patent claim 1 in that the filler material is mixed with a proportion of kapok fibers,
Dies liefert zum einen einen sehr positiven wirtschaftlichen Beitrag, da Kapokfasern mindestens um die Hälfte günstiger zu erhalten sind als PLA-Fasern. Ein technischer Vorteil besteht um anderen darin, dass die Kapokfasern ein reines Naturprodukt sind, sodass sich die Gesamtbi- lanz der für die Herstellung aufzuwendenden Energie deutlich verbessert, Ein weiterer Vorteil besteht darin, dass der hydrophobe Kapokanteil in Verbindung mit dem PLA-Faseranteil das bereits gute Feuchtigkeitsmanagement einer reinen PLA-Faserfüllung weiter verbessert.On the one hand, this makes a very positive economic contribution, since Kapok fibers are at least half cheaper to obtain than PLA fibers. Another technical advantage is that the kapok fibers are a purely natural product, so that the overall balance of the energy to be used for production is significantly improved. Another advantage is that the hydrophobic kapok component in conjunction with the PLA fiber component already does this good moisture management of a pure PLA fiber filling further improved.
Des Weiteren ergibt sich neben einem deutlich beschleunigten Feuchtigkeitstransport bei einer gleichzeitig gesteigerten Wasserdampfspeicherfähigkeit eine wesentlich verbesserte Wärmeisolationsfähigkeit. Die erzielten Werte können gegenüber denen eines Produkts aus reinen PLA-Fasern jeweils um etwa 10% verbessert sein.Furthermore, in addition to a significantly accelerated moisture transport with a simultaneously increased water vapor storage capacity, there is a significantly improved heat insulation capacity. The values achieved can be improved by around 10% in each case compared to those of a product made of pure PLA fibers.
Als besonders vorteilhaft ist hervorzuheben, dass durch den Anteil an Kapokfasern ein garantiert Bakterien und Milben freies Füllmaterial zur Verfügung gestellt werden kann, da die in den Kapokfasern enthaltenen Bitterstoffe ein Bakterienwachstum nicht nur nicht unterstützten, son- dem dieses wirkungsvoll verhindern, sodass auch die beteiligten PLA- Fasern an dem natürlichen Schutz partizipieren können. Für Hausstauballergiker ist ein mit diesem erfinderischen Füllmaterial versehenes Bettdeck oder Kissen deswegen besonders gut geeignet. Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination mit den weiteren Unteransprüchen.It is particularly advantageous to emphasize that the content of kapok fibers means that a filling material that is guaranteed to be free of bacteria and mites can be made available, since the bitter substances contained in the kapok fibers not only do not support bacterial growth, but also effectively prevent it, so that those involved also PLA fibers can participate in the natural protection. A bed cover or pillow provided with this inventive filling material is therefore particularly well suited for people allergic to house dust. Further advantageous embodiments of the subject matter of the invention result with and in combination with the further subclaims.
Der Gewichtsanteil an der beigemischten Kapokfaser kann je nach Anforderungsprofil an das Füllmaterial zwischen 5 und 95 % betragen.The proportion by weight of the admixed kapok fiber can be between 5 and 95% depending on the requirement profile for the filling material.
Das erfinderische Füllmaterial kann auch Anteile weiterer Fasermateria- lien aufweisen, sodass beliebige Anforderungen an das Füllmaterial befriedigt werden können.The filling material according to the invention can also have proportions of other fiber materials, so that any requirements placed on the filling material can be met.
Ganz besonders Vorteilhaft ist die Verarbeitung des erfinderischen Füllmaterials zu einem Mischfaservlies, wodurch eine homogene Ver- teilung der einzelnen Anteile an PLA-Fasern und Kapokfasern gewährleistet werden kann.The processing of the inventive filler material into a mixed fiber fleece is particularly advantageous, as a result of which a homogeneous distribution of the individual portions of PLA fibers and Kapok fibers can be guaranteed.
Gemäß einer anderen zu bevorzugenden Ausführungsform besteht das Füllmaterial in einzelnen Lagen aus PLA-Faservlies und Kapokfaservlies, wodurch sich ebenfalls die Eigenschaften des daraus hergestellten Gegenstandes, etwa eine bestimmte Weichheit oder Härte bei einem ersten Hautkontakt erzeugen lässt, der möglicherweise bei einer als sehr bauschig hergestellten PLA-Faser ein wohligeres Gefühl erzeugt als die glattere Naturfaser aus Kapok, According to another preferred embodiment, the filler material consists of individual layers of PLA fiber fleece and kapok fiber fleece, which also allows the properties of the object produced therefrom, for example a certain softness or hardness, to be produced on first skin contact, which may be produced on one that is very bulky PLA fiber creates a more comfortable feeling than the smoother natural fiber from Kapok,
