Abstract

A spherical fiber aggregate having an inner core and outer covering, in particular as a filler material for cushions and covers wherein individual filaments or fibers are intertwined, is characterized in that the core of the fiber aggregate contains filaments or fibers different from those of the covering. In this manner spherical fiber aggregates are created, which combine different properties, and in particular are capable of absorbing humidity when used as a filler material, and therefore contain natural fibers, while on the other hand they do not lose their down-like properties, such as high bulk, compressive elasticity, softness, thermal insulation ability, light weight and ready adaptation to the body to be covered.

Description

Die Erfindung betrifft ein sphärisches Faseraggregat gemäß Oberbegriff des Anspruches 1.The invention relates to a spherical fiber aggregate according to the preamble of claim 1.

Aus der DE-B 2.301.913 ist ein Füllmaterial aus Formlingen mit einem runden Querschnitt bekannt. Dieses Füllmaterial wird somit aus sphärischen Faseraggregaten gebildet, wobei zur Herstellung des einzelnen Faseraggregates einzelne Fäden einer Länge von mindestens 200 mm verwendet werden. Diese Fäden werden durch einen Gasstrom voneinander getrennt, in ein Gefäß mit durchlochter Wandung eingeblasen, darin angesammelt und durch exzentrisches Einblasen eines Gasstroms in das Gefäß unter Ausbildung eines kugeligen Formlings in Rotation versetzt. Dabei entsteht ein Faseraggregat, welches in seinen räumlichen Außenbereichen eine größere Dichte aufweist, als in seinem Kernbereich. Für dieses Aggregat werden Synthetikfasern aus Polyamid, Polyester, Polyacrylsäure, Polyvinylalkohol, Polyvinylidenchlorid, Polyurethan oder Polyvinylchlorid benutzt. Es können auch verschiedene Synthetikfasern gemischt verwendet werden, die sich insbesondere in ihren thermoplastischen Eigenschaften unterscheiden. Infolge der gegenseitigen Befestigung der Fäden an deren Berührungspunkten können diese bekannten Aggregate sich nicht ineinander verhaken oder einander durchdringen. Wenngleich ein solches Faseraggregat ähnliche Eigenschaften, insbesondere in Bezug auf große Sperrigkeit, Druckelastizität, Weichheit, Wärmeisolierfähigkeit, geringes Gewicht und gute Anpassung an den einzuhüllenden Körper, wie Daunen aufweisen kann, kann es nicht als gleichwertiger Ersatz für Daunen angesehen werden, da ihm die Flüssigkeits-Absorptionsfähigkeit der Daunen fehlt.From DE-B 2,301,913 a filler material from molded articles with a round cross-section is known. This filler material is thus formed from spherical fiber aggregates, individual threads having a length of at least 200 mm being used to produce the individual fiber aggregate. These threads are separated from one another by a gas stream, blown into a vessel with a perforated wall, collected therein and rotated by eccentrically blowing a gas stream into the vessel to form a spherical molding. This creates a fiber aggregate that has a greater density in its spatial outer areas than in its core area. Synthetic fibers made of polyamide, polyester, polyacrylic acid, polyvinyl alcohol, polyvinylidene chloride, polyurethane or polyvinyl chloride are used for this unit. Different synthetic fibers can also be mixed, which differ in particular in their thermoplastic properties. As a result of the mutual fastening of the threads at their contact points, these known units cannot interlock or penetrate one another. Although such a fiber aggregate may have similar properties, in particular in terms of large bulkiness, elasticity in compression, softness, heat insulation ability, light weight and good adaptation to the body to be wrapped, such as down, it cannot be regarded as an equivalent substitute for down, since it contains the liquid -Down's absorbency is absent.

Aus der EP-A 0.013.427 ist ein weiteres Faseraggregat bekannt, welches aus sphärisch miteinander verschlungenen oder eingerollten Fasern besteht. Diese Aggregate sind riesel- und rollfähig und können natürliche Fasern, wie Baumwoll- oder Wollfasern, Tierhaare, wie Ziegenhaare, Pelzhaare od.dgl. oder Synthesefasern oder ein Gemisch davon aufweisen. Diese bekannten Aggregate weisen eine nadelfähige Dichte auf und sollen gemäß der EP-A 0.013.427 zu einer Schicht abgelegt miteinander und / oder mit einer Trägerschicht vernadelt werden, um dann ein textiles Flächengebilde zu bilden.Another fiber aggregate is known from EP-A 0.013.427, which consists of spherically intertwined or rolled fibers. These aggregates are free-flowing and rollable and can use natural fibers such as cotton or wool fibers, animal hair such as goat hair, fur hair or the like. or synthetic fibers or a mixture of them. These known aggregates have a needled density and, according to EP-A 0.013.427, are to be laid down to form a layer with one another and / or needled with a carrier layer, in order then to form a textile fabric.

Diese Faseraggregate haben sich zwar insbesondere für die Herstellung von Teppichen od.dgl. bewährt. Sie lassen sich im Prinzip auch als Füllmaterialien für Kissen, Decken od.dgl. verwenden. Handelt es sich dabei um synthetische Fasern, so können diese Aggregate jedoch in der Regel fast keine Feuchtigkeit aufnehmen. Aggregate mit natürlichen Fasern, wie Wolle od.dgl., können zwar relativ viel Feuchtigkeit, wie Schweiß oder andere Körperabscheidungen aufnehmen, solche Aggregate verfilzen jedoch sehr schnell, wodurch sie nicht nur in sich verklumpen, sondern sich auch mit anderen, benachbarten Aggregaten verbinden und dadurch das einzelne Aggregat und auch die Füllung als ganzes nicht mehr die anfangs vorhandenen elastischen Eigenschaften aufweisen. Als Füllmaterial für Kissen und Decken insbesondere für das Bett sind diese Faseraggregate deshalb weniger geeignet.These fiber aggregates have been made especially for the production of carpets or the like. proven. In principle, they can also be used as filling materials for pillows, blankets or the like. use. If these are synthetic fibers, however, these aggregates can generally absorb almost no moisture. Aggregates with natural fibers, such as wool or the like, can absorb a relatively large amount of moisture, such as sweat or other body deposits, but such aggregates become matted very quickly, which not only clumps in them, but also connects with other, neighboring aggregates and As a result, the individual aggregate and the filling as a whole no longer have the elastic properties that were initially present. These fiber aggregates are therefore less suitable as filling material for pillows and blankets, especially for the bed.

Der Erfindung liegt deshalb die Aufgabe zugrunde, gattungsgemäße sphärische Faseraggregate zu schaffen, die verschiedene Eigenschaften miteinander kombinieren, insbesondere zum einen als Füllmaterial auch Feuchtigkeit absorbieren können und deshalb insbesondere natürliche Fasern aufweisen, andererseits aber nicht ihre den Daunen ähnliche Eigenschaften, wie große Sperrigkeit, Druckelastizität, Weichheit, Wärmeisolierfähigkeit, geringes Gewicht und gute Anpassung an den einzuhüllenden Körper, verlieren.The invention is therefore based on the object of creating generic spherical fiber aggregates which combine different properties with one another, in particular on the one hand can also absorb moisture as a filler and therefore in particular have natural fibers, but on the other hand do not have their properties similar to those of down, such as large bulkiness, pressure elasticity , Softness, heat insulation ability, light weight and good adaptation to the body to be wrapped.

Diese Aufgabe wird durch die Erfindung gelöst wie sie in den Anspruchen 1 bis 8 gekennzeichnet ist. Das erfindungsgemäße Faseraggregat ist gemäß Anspruch 1 dadurch gekennzeichnet, daß im Kern des Faseraggregates andere Fasern angeordnet sind, als in der Hülle desselben. Dadurch kann man den Fasern des Aggregatkernes andere Aufgabe übertragen, wie den Fasern der Aggregathülle.This object is achieved by the invention as characterized in claims 1 to 8. The fiber aggregate according to the invention is characterized according to claim 1, characterized in that different fibers are arranged in the core of the fiber aggregate than in the sheath of the same. This enables the fibers of the aggregate core to be assigned a different task, such as the fibers of the aggregate shell.

Die Fasern der Hülle können natürliche Fasern sein, während die Fasern des Kerns synthetische Fasern sind. Durch die außenliegenden natürlichen Fasern erscheint das Faseraggregat außerlich als nur aus natürlichen Fasern bestehend, was insbesondere dann wichtig ist, wenn diese Faseraggregate direkt oder indirekt durch eine Umhüllung mit der menschlichen Haut in Berührung kommen. Die innenliegenden synthetischen Fasern können dann im wesentlichen eine Stützfunktion für die außenliegenden natürlichen Fasern übernehmen.The fibers of the shell can be natural fibers while the fibers of the core are synthetic fibers. Due to the external natural fibers, the fiber aggregate appears to consist only of natural fibers, which is particularly important when these fiber aggregates come into direct or indirect contact with human skin through a covering. The synthetic fibers on the inside can then essentially take on a supporting function for the natural fibers on the outside.

Die Fasern der Hülle können aber auch im wesentlichen die mechanischen Eigenschaften übernehmen, während den Fasern im Kern des Aggregates dann im wesentlichen die Aufgabe der Flüssigkeitsabsorption und der Wärmeisolierung zukommt. Dementsprechend sind gemäß einer anderen Ausführungsform der Erfindung im Kern natürliche Fasern, wie z.B. Baumwoll- oder Schafwollfasern angeordnet, während in der Hülle synthetische und insbesondere steifere Fasern vorgesehen sind.The fibers of the sheath can also take over essentially the mechanical properties, while the fibers in the core of the unit then essentially have the task of liquid absorption and thermal insulation. Accordingly, according to another embodiment of the invention, natural fibers such as e.g. Cotton or sheep wool fibers are arranged, while synthetic and in particular stiffer fibers are provided in the casing.

Solche synthetischen Fasern sollten wasserabstoßend ausgebildet sein, wobei hier besonders Polypropylenfasern geeignet sind.Such synthetic fibers should be water-repellent, polypropylene fibers being particularly suitable here.

Der Kern des Faseraggregates kann aber auch feine, insbesondere feuchtigkeitsabsorbierende Fasern enthalten, während die Hülle des Aggregates grobe, feuchtigkeistabstoßende Fasern enthält.The core of the fiber aggregate can also contain fine, in particular moisture-absorbing fibers, while the shell of the aggregate contains coarse, moisture-repellent fibers.

Um die Hülle mit dem Kern des Aggregates dauerhaft zu verbinden, liegen vorteilhafterweise Fasern der Hülle vor, die in den Kern eingedrungen sind; insbesondere sind diese Fasern in den Kern hineingenadelt.In order to permanently connect the casing to the core of the assembly, there are advantageously fibers of the casing which have penetrated into the core; in particular, these fibers are needled into the core.

Solche Faseraggregate lassen sich z.B. dadurch herstellen, daß um ein den Kern bildendes Faseraggregat weitere andere Fasern in einem zweiten bekannten Verkugelungsverfahrensschritt aufgewickelt werden.Such fiber aggregates can e.g. in that further other fibers are wound around a fiber aggregate forming the core in a second known balling process step.
