Definitions
- the invention relates to a spherical fiber aggregate, in particular as a filling material for blankets, such as duvets, pillows or the like, made of fibers and / or threads which are spherically entangled and essentially form a fiber ball.
- Blankets are meant to protect the human body. They create a zone between the body and the ambient air, which inhibits heat exchange between the body and the environment and thereby reduces the heat radiation from the human body, thereby preventing hypothermia of the resting body.
- the retention of heat by means of a blanket is essentially achieved by creating an air volume above the human body which is immovable, ie the effect is essentially achieved by a resting air cushion, the The fact that air has a poor heat conduction coefficient is exploited.
- Valuable duvets are therefore filled with down that is itself relatively light, but whose bulk makes it possible to make a large volume available. However, down is very expensive and is not available in unlimited quantities.
- Such a nonwoven fabric made of synthetic fibers is known, for example, from US Pat. No. 4,588,635.
- This nonwoven fabric consists of a fiber mixture in which at least one type has crimped fibers and in which the different fibers also have a different modulus of elasticity.
- pillows in particular pillows, are filled with spherical fiber aggregates made of fibers and / or threads, which are spherically entangled and essentially form a fiber ball.
- the fiber aggregates used here are basically known from EP-A-0 013 427. Fibers are described there, which are tangled 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, e.g. Cotton or wool fibers, animal hair or the like. or synthetic fibers, e.g. Polyamide, polyester, polypropylene fibers or the like. or a mixture of these. In particular, these fiber balls can be crimped fibers, e.g.
- fiber balls have crimped synthetic fibers.
- Such fiber balls have hitherto been used essentially for textile fabrics, in particular for carpet manufacture, for clothing fabrics, bed covers, decorative fabrics or textile coverings.
- These fiber balls as described in EP-A-0 013 427, are suitable as filling material if they contain binders which ensure that the individual balls do not dissolve and break down into their individual fibers.
- the fiber balls used in the pillows have the task of supporting the head of a user. Since the head lies on the pillow, the total weight of the pillow is less relevant for the sleeper than with a duvet that lies on the sleeper.
- the binding fibers have an elasticity that differs from that of the main fibers.
- 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.
- the binding fibers had a lower modulus than the main fibers.
- the binding fibers are preferably coarser and / or stiffer than the main fibers.
- the binding fibers used in particular are synthetic fibers.
- the invention has for its object to provide generic fiber aggregates, or the like, in particular for use as a filling material in blankets, such as duvets, pillows. have better properties.
- the fiber balls according to the invention have a mixture of fibers, one type of fiber having a small modulus of elasticity, while another type of fiber has a much greater modulus of elasticity and the fibers with the larger modulus of elasticity taper over their length.
- the two types of fibers differ in particular in that the fibers with the low modulus of elasticity can be sphered very well, while the fibers with the much larger modulus of elasticity can only be sphered very poorly or not at all, since they have a very high internal resilience.
- the fibers have different diameters at their respective ends. As a result, there is a different elasticity in these fibers even over the length of these fibers. This can have a positive effect when processing the fibers.
- a fiber ball made from such a mixture of fibers surprisingly has a very large volume and is therefore much bulkier than the known fiber balls.
- the fiber ball has a density that is significantly smaller than the density of the known fiber balls, as a result of which the fiber balls have a very large volume of air with a relatively low weight. Therefore, such fiber balls are particularly suitable for blankets, such as duvets or the like, which should let as little heat as possible pass through a large, resting inner air cushion, but on the other hand should not be too heavy.
- the fibers with the smaller modulus of elasticity are crimped, while the fibers with the large modulus of elasticity are substantially uncrimped.
- the fibers with the larger modulus of elasticity are preferably coarser and / or stiffer than the fibers with the smaller modulus of elasticity.
- the fibers used for these fiber balls can be natural fibers, e.g. Cotton or wool fibers, animal hair or the like. or synthetic fibers, e.g. Polyamide, polyester, polypropylene fibers or the like. with the respective properties according to the invention.
- both the fibers with the larger modulus of elasticity and the fibers with the smaller modulus of elasticity are natural fibers. Natural fibers in the blankets not only make them more valuable, they also promote sleeping comfort.
- the fiber balls can be produced by the method described in EP-A-0 013 427.

Description
- Die Erfindung betrifft ein sphärisches Faseraggregat, insbesondere als Füllmaterial für Decken, wie Bettdecken, Kissen od.dgl., aus Fasern und / oder Fäden, die sphärisch verwickelt sind und im wesentlichen eine Faserkugel bilden.
- Decken, insbesondere Bettdecken, sollen den menschlichen Körper schützen. Sie schaffen zwischen dem Körper und der Umgebungsluft eine Zone, die einen Wärmeaustausch zwischen dem Körper und der Umgebung hemmt und dadurch die Wärmeabstrahlung des menschlichen Körpers verringert, wodurch eine Unterkühlung des ruhenden Körpers verhindert wird.
- Das Rückhalten der Wärme mittels einer Decke, wie Bettdecke od.dgl., wird im wesentlichen dadurch erreicht, daß ein Luftvolumen über dem menschlichen Körper geschaffen wird, welches unbewegbar ist, d.h., die Wirkung wird im wesentlichen durch ein ruhendes Luftpolster erreicht, wobei der Umstand ausgenutzt wird, daß Luft einen schlechten Wärmeleitungskoeffizienten aufweist.
- Je größer nun dieses Luftvolumen ist, desto größer ist auch das Wärmerückhaltevermögen der Decke. Dieses größere Luftvolumen kann aber in der Regel nur durch ein größeres Gewicht der Decke erreicht werden.
- Wertvolle Bettdecken sind deshalb mit Daunen gefüllt, die selbst relativ leicht sind, durch deren Bauschigkeit jedoch ein großes Volumen zur Verfügung gestellt werden kann. Daunen sind jedoch sehr teuer und auch nicht in unbegrenzten Mengen erhältlich.
- Es wurde auch schon vorgeschlagen, Bettdecken mit einem Faservlies zu füllen. Die dabei verwendeten Fasermaterialien sind jedoch bei einem akzeptablen Flächengewicht nicht in der Lage, auch ein ausreichendes Volumen zur Verfügung zu stellen.
- Ein solches Faservlies aus synthetischen Fasern ist z.B. aus der US-A-4 588 635 bekannt. Dieses Faservlies besteht aus einer Fasermischung, bei der zumindest eine Sorte gekräuselte Fasern aufweist und bei der die unterschiedlichen Fasern auch einen unterschiedlichen Elastizitätsmodul aufweisen.
- Gemäß einem neueren, nicht vorveröffentlichten Vorschlag, werden Kissen, insbesondere Kopfkissen mit sphärischen Faseraggregaten aus Fasern und / oder Fäden, die sphärisch verwickelt sind und im wesentlichen eine Faserkugel bilden, gefüllt.
- Die dabei verwendeten Faseraggregate sind grundsätzlich aus der EP-A-0 013 427 bekannt. Dort werden Fasern beschrieben, die 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, wie z.B. gekräuselte Synthesefasern aufweisen. 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.
- Die in den Kissen, insbesondere Kopfkissen, verwendeten Faserkugeln haben die Aufgabe, den Kopf eines Benutzers abzustützen. Da der Kopf auf dem Kissen liegt, ist das Gesamtgewicht des Kissens für den Schläfer weniger relevant, als bei einer Bettdecke, die auf dem Schläfer liegt.
- Aus der nicht vorveröffentlichten EP-A-0 277 494 sind Faserkugeln bekannt, die ein Gemisch von Hauptfasern und Bindefasern aufweisen. Liegen diese Bindefasern mit den Hauptfasern verteilt vor, so können die Bindefasern die Hauptfasern verbinden.
- Um eine entsprechende Verteilung der Bindefasern innerhalb der Faserkugeln gemäß der EP-A-0 277 494 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.
- Gemäß einer dort beschriebenen Ausführungsform wiesen die Bindefasern einen geringeren Modul auf, als die Hauptfasern. Bevorzugt sind die Bindefasern gröber und / oder steifer, als die Hauptfasern. Insbesondere die dabei verwendeten Bindefasern sind synthetische Fasern.
- Der Erfindung liegt die Aufgabe zugrunde, gattungsgemäße Faseraggregate zu schaffen, die insbesondere für einen Einsatz als Füllmaterial in Decken, wie Bettdecken, Kissen od.dgl. bessere Eigenschaften aufweisen.
- Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Die erfindungsgemäßen Faserkugeln weisen ein Gemisch von Fasern auf, wobei eine Sorte von Fasern einen kleinen Elastizitätsmodul aufweist, während eine andere Sorte von Fasern einen demgegenüber viel größeren Elastizitätsmodul aufweist und die Fasern mit dem größeren Elastizitätsmodul sich über ihre Länge verjüngen.
- Die beiden Faserarten unterscheiden sich insbesondere auch darin, daß die Fasern mit dem geringen Elastizitätsmodul sich sehr gut verkugeln lassen, während die Fasern mit dem viel größeren Elastizitätsmodul sich nur sehr schlecht bis überhaupt nicht verkugeln lassen, da sie eine sehr große innere Rückfederkraft aufweisen. Die Fasern weisen an ihren jeweiligen Enden unterschiedliche Durchmesser auf. Dadurch liegt in diesen Fasern eine unterschiedliche Elastizität auch über die Länge dieser Fasern vor. Dies kann sich beim Verarbeiten der Fasern positiv auswirken.
- Eine Faserkugel aus einem solchen Gemisch von Fasern hat überraschender Weise ein sehr großes Volumen und ist damit viel bauschiger, als die bekannten Faserkugeln. D.h., eine solche Faserkugel weist eine Dichte auf, die wesentlich kleiner ist, als die Dichte der bekannten Faserkugeln, wodurch die Faserkugeln bei relativ geringem Gewicht ein sehr großes Luftvolumen aufweisen. Deshalb eignen sich solche Faserkugeln insbesondere für Decken, wie Bettdecken od.dgl., die durch ein großes ruhendes inneres Luftpolster möglichst wenig Wärme durchlassen sollen, andererseits jedoch nicht allzu schwer sein sollen.
- Gemäß einer Ausführungsform sind die Fasern mit dem kleineren Elastizitätsmodul gekräuselt, während die Fasern mit dem großen Elastizitätsmodul im wesentlichen ungekräuselt sind.
- Vorzugsweise sind die Fasern mit dem größeren Elastizitätsmodul gröber und / oder steifer ausgebildet, als die Fasern mit dem kleineren Elastizitätsmodul.
- Die für diese Faserkugeln verwendeten Fasern können natürliche Fasern, z.B. Baumwoll- oder Wollfasern, Tierhaare od.dgl. oder Synthesefasern, z.B. Polyamid-, Polyester-, Polypropylenfasern od.dgl. mit den jeweiligen Eigenschaften gemäß der Erfindung sein.
- Gemäß einer bevorzugten Ausführungsform sind sowohl die Fasern mit dem größeren Elastizitätsmodul, als auch die Fasern mit dem kleineren Elastizitätsmodul natürliche Fasern. Natürliche Fasern in den Decken machen diese nicht nur wertvoller, der Schlafkomfort wird dadurch auch gefördert.
- Die Faserkugeln können nach dem in der EP-A-0 013 427 beschriebenen Verfahren hergestellt werden.
