Description

Die Erfindung betrifft ein sphärisches Faseraggregat, insbesondere als Füll- oder Polstermaterial aus Fasern und / oder Fäden, die sphärisch verwickelt sind und im wesentlichen eine Faserkugel bilden.The invention relates to a spherical fiber aggregate, in particular as a filling or cushioning material made of fibers and / or threads, which are spherically entangled and essentially form a fiber ball.

Aus der EP-A-0.203.469 sind Faserkugeln bekannt, die als Füll- oder Polstermaterial verwendet werden können. Diese Faserkugeln bestehen aus spiralgekräuselten miteinander verwickelten Polyesterfasern mit einer Länge von etwa 10 bis 60 mm und weisen einen Durchmesser zwischen 1 und 15 mm auf. Die Faserkugeln besitzen eine Elastizität, durch die sich die Kugeln nach einem Zusammendrücken - auch über längere Zeit hinweg - wieder wesentlich (Erholungsgrad von 80 %) erholen. Die Faserkugeln besitzen untereinander eine Kohäsion von weniger als 6 Newton, vorzugsweise von weniger als 4,5 Newton (gemäß einem dort beschriebenen Meßverfahren).From EP-A-0.203.469 fiber balls are known which can be used as filler or cushioning material. These fiber balls consist of spirally crimped polyester fibers with a length of about 10 to 60 mm and a diameter of between 1 and 15 mm. The fiber balls have an elasticity, through which the balls recover significantly after a compression - even over a long time (recovery rate of 80%). The fiber balls have a cohesion of less than 6 Newtons, preferably less than 4.5 Newtons (according to a measuring method described there).

Durch diese geringen Kohäsionskräfte verschieben sich die Faserkugeln innerhalb einer Füllung sehr leicht, insbesondere, wenn diese Füllung für ein Kopfkissen benutzt wird. Liegt der Schläfer mit dem Kopf mittig auf einem mit einem mit solchen Faserkugeln gefüllten Kissen, drückt sich dieses Kissen im Auflagebereich sehr leicht durch. Um dies zu verhindern, müssen die Faserkugeln eine sehr hohe Dichte aufweisen, weshalb die Kissen selbst sehr schwer werden. Dadurch verliert das Kissen wiederum seine "Weichheit", was manche Menschen als unangenehm empfinden.Due to these low cohesive forces, the fiber balls move very easily within a filling, especially if this filling is used for a pillow. If the sleeper lies with his head in the middle of a pillow filled with such fiber balls, this pillow pushes through very easily in the support area. To prevent this, the fiber balls must have a very high density, which is why the pillows themselves are very heavy. As a result, the pillow loses its "softness", which some people find uncomfortable.

Aus der EP-A-0.013.427 sind sphärische Faseraggregate bekannt, in denen Fasern zu Faserkugeln verwickelt sind. Diese Faserkugeln weisen einen Durchmesser von mindestens 3 mm auf. Die Kugeln können auch einen Durchmesser bis zu 50 mm aufweisen. Die dort verwendeten Fasern haben eine länge von mindestens 15 mm, vorzugsweise zwischen 40 und 120 mm. Die Faserkugeln weisen eine Dichte zwischen 0,01 und 0,1 g/cm³ auf. Die Fasern dieser Faserkugeln können natürliche Fasern, z.B. Baumwoll- ­oder Wollfasern, Tierhaare od.dgl. oder Synthesefasern, z.B. Polyamid-, Polyester-, Polypropylenfasern od.dgl. oder ein Gemisch aus diesen sein. Insbesondere können diese Faserkugeln gekräuselte Fasern, z.B. gekräuselte Synthesefasern sein. Solche Faserkugeln wurden bisher im wesentlichen für textile Flächengebilde, insbesondere für die Teppichherstellung, für Bekleidungsstoffe, Schlafdecken, Dekorationsstoffe oder textile Bezugsstoffe benutzt. Als Füllmaterial sind diese Faserkugeln, wie sie in der EP-A-0.013.427 beschrieben sind, dann geeignet, wenn sie Bindemittel enthalten, welche dafür sorgen, daß sich die einzelnen Kugeln nicht auflösen und in ihre Einzelfasern zerlegen.Spherical fiber aggregates are known from EP-A-0.013.427, in which fibers are entangled into fiber balls. These fiber balls have a diameter of at least 3 mm. The balls can also have a diameter of up to 50 mm. The fibers used there have a length of at least 15 mm, preferably between 40 and 120 mm. The fiber balls have a density between 0.01 and 0.1 g / cm³. The fibers of these fiber balls can be natural fibers, for example cotton or wool fibers, Animal hair or the like or synthetic fibers, for example polyamide, polyester, polypropylene fibers or the like. or a mixture of these. In particular, these fiber balls can be crimped fibers, for example crimped synthetic fibers. Such fiber balls have hitherto been used essentially for textile fabrics, in particular for carpet manufacture, for clothing fabrics, bedspreads, decorative fabrics or textile coverings. These fiber balls, as described in EP-A-0.013.427, are suitable as filler material if they contain binders which ensure that the individual balls do not dissolve and break down into their individual fibers.

Der Erfindung liegt die Aufgabe zugrunde, gattungsgemäße Faseraggregate zu schaffen, die insbesondere für einen Einsatz als Füllmaterial bessere Eigenschaften aufweisen.The invention has for its object to provide generic fiber aggregates that have better properties especially for use as a filler.

Diese Aufgabe wird durch die Erfindung gelöst. Die erfindungsgemäßen Faserkugeln weisen ein Gemisch von Hauptfasern und Bindefasern auf. Liegen diese Bindefasern mit den Hauptfasern verteilt vor, so können die Bindefasern die Hauptfasern verbinden.This object is achieved by the invention. The fiber balls according to the invention have a mixture of main fibers and binding fibers. If these binding fibers are distributed with the main fibers, the binding fibers can connect the main fibers.

Um eine entsprechende Verteilung der Bindefasern innerhalb der Faserkugeln zu erhalten, weisen die Bindefasern eine von den Hauptfasern abweichende Elastizität auf. Beim Herstellen (Verkugeln) der Faserkugeln wird durch die unterschiedliche Elastizität der Fasern dafür gesorgt, daß die unterschiedlichen Fasertypen sich insbesondere kreuzen. An den Kreuzungsstellen können dann Verbindungen zwischen den beiden Fasertypen hergestellt werden.In order to obtain a corresponding distribution of the binding fibers within the fiber balls, the binding fibers have a different elasticity from the main fibers. When producing (balling) the fiber balls, the different elasticity of the fibers ensures that the different fiber types in particular intersect. Connections between the two fiber types can then be made at the crossing points.

Gemäß einer Ausführungsform der Erfindung wiesen die Bindefasern einen geringeren Modul auf, als die Hauptfasern. Bevorzugt sind die Bindefasern gröber und / oder steifer, als die Hauptfasern.According to one embodiment of the invention, the binding fibers had a lower modulus than the main fibers. The binding fibers are preferably coarser and / or stiffer than the main fibers.

Bevorzugt sind die Bindefasern Zweikomponentenfasern, wobei die eine Komponente gegenüber der anderen Komponente insbesondere einen starken, tragenden Modul aufweist. Es reicht dann aus, daß die eine Komponente eine Bindewirkung ausüben kann.The binding fibers are preferably two-component fibers, one component compared to the other component in particular has a strong, load-bearing module. It is then sufficient that the one component can have a binding effect.

Die Bindefasern können als Kernmantelfasern ausgebildet sein, wobei vorzugsweise die Hochmodulkomponente innen und die Bindekomponente außen angeordnet ist. Die Bindefasern können aber auch Side-by-side-Fasern sein, wobei die Bindekomponente einen halbkreisförmigen bis viertelmondförmgen Querschnitt aufweist.The binding fibers can be formed as core sheath fibers, the high modulus component preferably being arranged on the inside and the binding component on the outside. However, the binding fibers can also be side-by-side fibers, the binding component having a semicircular to quarter-moon-shaped cross section.

Gemäß einer bevorzugten Ausführungsform bestehen die Bindefasern aus den beiden Komponenten Polyäthylen und Polypropylen bestehen, die beide etwa einen halbkreisförmigen Querschnitt in den Bindefasern einnehmen. Dann können die Bindefasern ungefähr die gleiche Länge und Dicke aufweisen, wie die Hauptfasern. Eine solche Faserkugel hat überraschender Weise eine sehr große Elastizität, die wesentlich größer ist, als bei den bekannten Faserkugeln. Es scheint dann ein dreidimensionales gebundenes Netzwerk aller Fasern in einer Faserkugel vorzuliegen.According to a preferred embodiment, the binding fibers consist of the two components, polyethylene and polypropylene, both of which occupy approximately a semicircular cross section in the binding fibers. Then the binding fibers can have approximately the same length and thickness as the main fibers. Such a fiber ball surprisingly has a very high elasticity, which is much greater than in the known fiber balls. There then appears to be a three-dimensional bound network of all fibers in a fiber ball.

Gemäß einer Ausführungsform der Erfindung sind die Bindefasern wesentlich länger, als die Hauptfasern und weisen insbesondere eine Länge von 60 bis 90 mm auf. Dann sind auch die Bindefasern innerhalb der Faserkugel verwickelt.According to one embodiment of the invention, the binding fibers are substantially longer than the main fibers and in particular have a length of 60 to 90 mm. Then the binding fibers are also entangled within the fiber ball.

Gemäß einer anderen Ausführungsform sind die Bindefasern wesentlich kürzer, als die Hauptfasern und weisen insbesondere eine Länge auf, die etwa dem Durchmesser der Faserkugel entspricht. Dann sind die Bindefasern innerhalb der Faserkugel vorzugsweise etwa diametral angeordnet sind. Dabei können die Bindefasern aus der Faserkugel herausstacheln.According to another embodiment, the binding fibers are substantially shorter than the main fibers and in particular have a length that corresponds approximately to the diameter of the fiber ball. Then the binding fibers are preferably arranged approximately diametrically within the fiber ball. The binding fibers can spur out of the fiber ball.

Durch die Erfindung können nun Faserkugeln zur Verfügung gestellt werden, die lockerer und größer ausgebildet werden können, ohne die Elastizität zu verlieren. Dadurch wird in einer Füllung, insbesondere Kissenfüllung, ein sehr guter Stützeffekt, dort für den Kopf, erreicht.The invention now makes it possible to provide fiber balls which can be made looser and larger without losing their elasticity. This will fill in, in particular Pillow filling, a very good support effect, achieved there for the head.

Die Faserkugeln können nach dem in der EP-A-0.203.469 oder in der EP-A-0.013.427 beschriebenen Verfahren hergestellt werden. Nach dem Kugelbilden werden die einzelnen Kugeln einer Wärmequelle zugeführt, durch die die Bindefasern angeschmolzen werden und an den Kreuzungsstellen, insbesondere mit den Hauptfasern, eine Verbindung von Faser zu Faser hergestellt.The fiber balls can be produced by the method described in EP-A-0.203.469 or in EP-A-0.013.427. After the spheres have been formed, the individual spheres are fed to a heat source through which the binding fibers are melted and a fiber-to-fiber connection is established at the crossing points, in particular with the main fibers.
