Description

Die Erfindung betrifft ein Füllmaterial für Bettwaren aus Mischfaservlies sowie ein Verfahren zu seiner Herstellung.The invention relates to a filler for bedding made of mixed fiber fleece and a process for its preparation.

Eine bekannte Gebäudeisolation, EP 1 275 789 A1 , besteht aus 70 bis 90 Gewichtsprozent Holzwolle, einem Anteil von bis zu 5% Pflanzenfasern und zwischen 10 und 30 Prozent Synthetikfasern und sie weist ein Gewicht von ca. 100 Kg/m3 auf. Als Füllmaterial für Bettwaren eignet sie sich insbesondere auf Grund des hohen Holzwolleanteils naturgemäß nicht.A well-known building insulation, EP 1 275 789 A1 , consists of 70 to 90 percent by weight of wood wool, a share of up to 5% vegetable fibers and between 10 and 30 percent synthetic fibers and has a weight of about 100 kg / m 3 . As a filler for bedding, it is naturally not suitable due to the high proportion of wood wool, of course.

Bekannt ist des Weiteren ein mattenförmiges Adsorptionsmaterial für auf Wasser schwimmendem oder darin emulgiertem Öl, WO 91/02041 A , bei dem die schlechte Öladsorption von Kapok durch Zugabe einer Bastfaser und deren mangelnder Zusammenhalt durch eine Polyesterfaser als thermoplastisches Verbindungsmittel verbessert wird.Also known is a mat-shaped adsorption material for oil floating on water or emulsified therein, WO 91/02041 A in which the bad oil adsorption of kapok is improved by adding a bast fiber and its lack of cohesion by a polyester fiber as a thermoplastic bonding agent.

Weiterhin ist ein Verbundwerkstoff bekannt, DE 198 32 721 A1 , der zur Stabilisierung einer Kernkomponente von Formteilen im Kraftfahrzeugbau schichtenweise zusammengesetzt ist. Naturfasern enthaltende textile Flächengebilde werden von einer aufgeschmolzenen Thermoplastschicht durchtränkt und mit einer Abdeckschicht verklebt.Furthermore, a composite material is known, DE 198 32 721 A1 , which is layered to stabilize a core component of automotive parts. Natural fiber-containing textile fabrics are impregnated by a molten thermoplastic layer and glued to a cover layer.

Es ist ein Mischfaservlies aus Schafschurwolle und Kapok bekannt, das als Füllmaterial für Bettwaren, Bekleidung, Kinderausstattung und dergl. verwandt wird, um vor allem den hygienischen Bedürfnissen Rechnung zu tragen und gleichzeitig ein reines Naturprodukt anbieten zu können, welches auch umweltfreundlich entsorgt werden kann.It is a mixed fiber fleece of sheep wool and kapok known, which is used as a filler for bedding, clothing, children's equipment and the like In order to meet the hygienic needs and at the same time be able to offer a pure natural product, which can also be disposed of in an environmentally friendly manner.

Nachteilig an diesem bekannten Mischfaservlies ist insbesondere, dass es zwar waschbar ist, dass jedoch mit jeder Wäsche ein Teil der Bauschkraft des Mischfaservlieses verloren geht, sodass die Lebensdauer der damit hergestellten Waren beschränkt ist.A disadvantage of this known mixed fiber nonwoven is in particular that although it is washable, but that with each wash a part of the bulk of the mixed fiber fleece is lost, so that the life of the goods produced therewith is limited.

Aufgabe der Erfindung ist es, ein Füllmaterial für Bettwaren aus Mischfaservlies zur Verfügung zu stellen, welches über einen längeren Zeitraum seine dem Neuzustand entsprechenden Eigenschaften beibehält sowie ein Verfahren zur Herstellung eines solchen Füllmaterials bereitzuhalten.The object of the invention is to provide a filling material for bedding made of mixed fiber fleece available, which maintains its properties corresponding to the new state over a longer period of time and to provide a process for producing such a filler.

Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Oberbegriffsmerkmalen der Ansprüche 1 und 3 erfindungsgemäß durch die in den kennzeichnenden Teilen derselben Patentansprüche angegebenen technischen Lehren.The solution of this object is achieved in conjunction with the preamble features of claims 1 and 3 according to the invention by the specified in the characterizing parts of the same claims technical teaching.

Dadurch, dass das Füllmaterial für Bettwaren aus einem Mischfaservlies aus einer Mischung von feinen Polyesterfasern und Kapokfasern besteht, wird ein Füllmaterial zur Verfügung gestellt, welches mit dem Gesamtprodukt zusammen voll waschbar bleibt, wobei der Synthetikfaser-Anteil für den Erhalt der Bauschkraft in dem Mischfaservlies sorgt, wo hingegen der Kapokanteil antibakteriell wirkt und eine Hausstaubmilbenfreiheit gewährleistet, sodass das Gesamtprodukt, um den hygienischen Bedürfnissen zu genügen, letztlich nicht so oft gewaschen werden muss wie beispielsweise Bettwaren, die nur aus Synthetikfasern bestehen.Characterized in that the filler for bedding material consists of a mixed fiber fleece of a mixture of fine polyester fibers and kapok fibers, a filler material is provided, which remains fully washable together with the total product, wherein the synthetic fiber content provides for the maintenance of the bulk in the mixed fiber fleece In contrast, where the Kapokanteil has an antibacterial effect and ensures a house dust mite free, so that the entire product to meet the hygienic needs, ultimately need not be washed as often as bedding, which consist only of synthetic fibers.

Die Synthetikfasern und die Kapokfasern sind des Weiteren homogen miteinander vervliest, sodass eine problemlose Weiterverarbeitung möglich wird und die vorteilhaften Eigenschaften des Mischfaservlieses gleichmäßig zur Geltung kommen.Furthermore, the synthetic fibers and the kapok fibers are homogeneously woven together so that easy further processing is possible and the advantageous properties of the mixed fiber nonwoven evenly come into their own.

Die Synthetikfasern aus Polyester (PES) können dabei wahlfrei aus Vollfasern, Hohlfasern und/ oder aus 3-D-Fasern bestehen.The synthetic fibers made of polyester (PES) can optionally consist of solid fibers, hollow fibers and / or 3-D fibers.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject of the invention will become apparent with and in combination from the following subclaims.

Bei einer weiteren bevorzugten Ausführungsform des erfinderischen Füllmaterials sind einzelne Lagen aus miteinander vervliestem Polyester-Kapokvlies mit weiteren einzelnen Lagen schichttechnisch miteinander vervliest, wobei zwei oder mehr Lagen übereinander angeordnet sein können. Solche Lagen können nicht nur aus reinem Polyestervlies oder reinem Kapokvlies sondern auch aus miteinander vervliesten Synthetik- und Kapokfasern bestehen, sodass jeder gewünschte Anforderung an das Mischfaservlies entsprochen werden kann.In a further preferred embodiment of the inventive filling material individual layers of polyester fleece woven together with other individual layers are stratified together layer-wise, wherein two or more layers can be arranged one above the other. Such layers can consist not only of pure polyester fleece or pure Kapokvlies but also of mutually woven synthetic and Kapokfasern, so that any desired requirement can be met to the mixed fiber fleece.

Der Anteil der Kapokfasern an dem gesamten Mischfaservlies kann dabei so klein sein, dass er gerade noch die Hausstaubmilbenfreiheit garantieren kann oder auch beliebig größer gewählt werden, je nach dem, wie hoch die Anforderungen daran gestellt werden oder wie die Gesamteigenschaften des Mischfaservlieses eingestellt werden sollen.The proportion of kapok fibers on the entire mixed fiber fleece can be so small that it can just guarantee the house dust mite freedom or be chosen arbitrarily larger, depending on how high the requirements placed on it or how the overall properties of the composite fiber fleece should be adjusted.

Alles in allem wird ein Füllmaterial für Bettwaren aus einem Mischfaservlies zur Verfügung gestellt, welches bei gleicher Dicke wie ein bekanntes Mischfaservlies aus Schafschurwolle und Kapok deutlich leichter ist und so, beispielsweise bei der Verarbeitung als Füllmaterial für Bettdecken, ein erheblich luftigeres und angenehmeres Gefühl bei einem Benutzer erzeugt als das bekannte, sehr viel schwerere Mischfaservlies aus reinen Naturprodukten.All in all, a filling material for bedding made of a mixed fiber fleece is provided, which is much easier with the same thickness as a known mixed fiber fleece of pure new wool and Kapok and so, for example when processing as a filling material for duvets, a considerably airier and more pleasant feeling at a User produced as the well-known, much heavier mixed fiber nonwoven made of pure natural products.

Zur Herstellung des Füllmaterials für Bettwaren aus einem Mischfaservlies werden die zu vermischenden Fasern vorab mechanisch in einem vorher bestimmten Mischungsverhältnis aufgelockert. Diesen Vorgang erledigt ein Ballenöffner, bei dem die Fasern über ein Nadellattentuch gegen eine entgegenlaufende, mit Nadeln besetzte Walze transportiert werden. Die Nadeln der Walze kämmen die überschüssigen Fasern aus dem Nadellattenband und werfen sie dadurch zurück zu den noch zu öffnenden Fasern, wodurch eine gleichmäßige Beschickung der nächsten Öffneranlage ermöglicht wird.To produce the filling material for bedding products from a mixed fiber fleece, the fibers to be mixed are pre-loosened mechanically in a predetermined mixing ratio. This process is done by a bale opener in which the fibers are transported via a needle flap cloth against a counter-rotating, needle-filled roller. The needles of the roll comb the excess fibers from the needle bar tape and thereby throw them back to the still open fibers, thereby allowing a uniform feed of the next opener system.

Die vorgeöffneten Fasern werden anschließend zu der als Feinöffner ausgebildeten nächsten Öffneranlage transportiert. Dieser Feinöffner dienst als zweite Faseröffnungseinrichtung. Die vorgemischten Fasern werden hier über mehrere mit Sägezahndraht garnierten Walzen, die unterschiedliche Durchmesser und teilweise entgegengesetzte Drehrichtungen haben, geschickt, damit die Fasern mehr oder weniger parallel zueinander laufen und etwaige Batzen oder Büschel aufgelöst werden. Dies ist notwendig, da die einzelnen Fasern der nachfolgenden lufttechnischen Anlage unbedingt separiert zugeführt werden müssen.The pre-opened fibers are then transported to the fine opener designed next Öffneranlage. This fine opener serves as a second fiber opening device. The premixed fibers are sent here via a plurality of sawtooth wire-impregnated rolls having different diameters and partially opposite directions of rotation, so that the fibers run more or less parallel to each other and any chunks or tufts are dissolved. This is necessary because the individual fibers must be fed to the subsequent ventilation system necessarily separated.

Die lufttechnische Anlage besteht aus zwei verschiedenen, ca. 80-200 m langen spezialbeschichteten Kunststoffschläuchen, die spiralförmig in einem Turm angeordnet sind. Des Weiteren gehören zu dieser Anlage zwei speziell für dieses Verfahren konstruierte Saugventilatoren, die die Fasern mit einer genau bemessenen Luftgeschwindigkeit aus dem Feinöffner durch den Turm befördern. Hierbei erfolgt die vollständig homogene Vermischung, da sich die beiden Fasern in dem Luftstrom des Schlauches verbinden und durch eine bestimmte Reibung, die durch die Strömungsgeschwindigkeit erzielt wird, zusammen fügen.The ventilation system consists of two different, about 80-200 m long special coated plastic hoses, which are arranged spirally in a tower. Also included in this system are two suction fans specially designed for this process, which carry the fibers through the tower at a precisely measured air velocity from the fine opener. Here, the completely homogeneous mixing takes place, since the two fibers connect in the air flow of the hose and add by a certain friction, which is achieved by the flow velocity together.

Einzig dieses Verfahren ermöglicht eine 100%ig homogene Vermischung der beiden unterschiedlichen Faserarten.Only this method allows a 100% homogeneous mixing of the two different types of fibers.
