Abstract

PCT No. PCT/EP88/00966 Sec. 371 Date Oct. 31, 1989 Sec. 102(e) Date Oct. 31, 1989 PCT Filed Oct. 26, 1988 PCT Pub. No. WO89/06714 PCT Pub. Date Jul. 27, 1989.An aggregate of spherical fibers, particularly for use as filling material for blankets, such as quilts, pillows or the like comprises fibers and/or threads that are wrapped spherically and essentially form a fibrous ball. So that the properties of the aggregate of spherical fibers are better, particularly for use as filling material in blankets, such as quilts, pillows or the like, it is proposed that the fibrous balls contain a mixture of fibers, whereby one type of fiber has a higher modulus of elasticity compared to another type of fiber. The fibers with the higher modulus of elasticity can also taper over their length.

Description

Sphärisches Faseraggregat, insbesondere als Füllmaterial für Decken, wie Bettdecken, Kissen od.dgl. Spherical fiber aggregate, in particular as a filling material for blankets, such as duvets, pillows or the like.
Beschreibung • 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 bil¬ den.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.
Decken, insbesondere Bettdecken, sollen den menschli¬ chen Körper schützen. Sie schaffen zwischen dem Körper und der Umgebungsluft eine Zone, die einen Wärmeaustausch zwi¬ schen dem Körper und der Umgebung hemmt und dadurch die Wärmeabstrahlung des menschlichen Körpers verringert, wo¬ durch eine Unterkühlung des ruhenden Körpers verhindert wird.Blankets, especially duvets, are intended 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.
Das Rückhalten der Wärme mittels einer Decke, wie Bettdecke od.dgl., wird im wesentlichen dadurch erreicht, daß ein Luftvolumen über dem menschlichen Körper geschaf¬ fen wird, welches unbewegbar ist, d.h., die Wirkung wird im wesentlichen durch ein ruhendes Luftpolster erreicht, wobei der Umstand ausgenutzt wird, daß Luft einen schlech¬ ten Wärmeleitungskoeffizienten aufweist.The retention of heat by means of a blanket, such as a duvet or the like, is essentially achieved by creating an air volume above the human body which is immovable, ie the effect is essentially achieved by a still air cushion. taking advantage of the fact that air has a poor heat conduction coefficient.
Je größer nun dieses Luftvolumen ist, desto größer ist auch das Wär erückhaltevermδgen der Decke. Dieses grö¬ ßere Luftvolumen kann aber in der Regel nur durch ein grö¬ ßeres Gewicht der Decke erreicht werden.The greater this air volume, the greater the heat retention capacity of the ceiling. However, this larger air volume can generally only be achieved by increasing the weight of the ceiling.
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 un¬ begrenzten Mengen erhältlich.Valuable duvets are therefore filled with down, which is itself relatively light, but the bulk of which allows a large volume to be made available. However, down is very expensive and is also not available in unlimited quantities.
Es wurde auch schon vorgeschlagen, Bettdecken mit ei¬ nem Faservlies zu füllen. Die dabei verwendeten Fasermate¬ rialien sind jedoch bei einem akzeptablen Flächengewicht nicht in der Lage, auch ein ausreichendes Volumen zur Ver¬ fügung zu stellen. Gemäß einem neueren, nicht vorverδffentlichten Vor¬ schlag, werden Kissen, insbesondere Kopfkissen mit sphäri¬ schen Faseraggregaten aus Fasern und / oder Fäden, die sphärisch verwickelt sind und im wesentlichen eine Faser¬ kugel bilden, gefüllt.It has also been proposed to fill duvets with a non-woven fabric. The fiber materials used here, however, are not able, with an acceptable basis weight, to also provide a sufficient volume. According to a more recent, not previously published proposal, 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.
Die dabei verwendeten Faseraggregate sind grundsätz¬ lich aus der EP-A-0.013.427 bekannt. Dort werden Fasern beschrieben, die zu Faserkugeln verwickelt sind. Diese Fa¬ serkugeln 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-, Polypro¬ pylenfasern od.dgl. oder ein Gemisch aus diesen sein. Ins¬ besondere können diese Faserkugeln gekräuselte Fasern, wie z.B. gekräuselte Synthesefasern aufweisen. Solche Faserku¬ geln wurden bisher im wesentlichen für textile Flächenge¬ bilde, insbesondere für die Teppichherstellung, für Be¬ kleidungsstoffe, 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, wel¬ che dafür sorgen, daß sich die einzelnen Kugeln nicht auf¬ lösen und in ihre Einzelfasern zerlegen.The fiber aggregates used are known in principle from EP-A-0.013.427. There fibers are described, which 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 / cm 3 . 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 have crimped fibers, such as 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.
Die in den Kissen, insbesondere Kopfkissen, verwende¬ ten Faserkugeln haben die Aufgabe, den Kopf eines Benut¬ zers abzustützen. Da der Kopf auf dem Kissen liegt, ist das Gesamtgewicht des Kissens für den Schläfer weniger re¬ levant, als bei einer Bettdecke, die auf dem Schläfer liegt.The fiber balls used in the pillows, in particular 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.
Der Erfindung liegt die Aufgabe zugrunde, gattungsge¬ mäße Faseraggregate zu schaffen, die insbesondere für ei¬ nen Einsatz als Füllmaterial in Decken, wie Bettdecken, Kissen od.dgl. bessere Eigenschaften aufweisen. Diese Aufgabe wird durch die Erfindung gelöst. Die erfindungsgemäßen Faserkugeln weisen ein Gemisch von Fa¬ sern auf, wobei eine Sorte von Fasern einen kleinen Ela¬ stizitätsmodul aufweist, während eine andere Sorte von Fa¬ sern einen demgegenüber viel größeren Elastizitätsmodul aufweist.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. This object is achieved by the invention. 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 having a much greater modulus of elasticity.
Die beiden Faserarten unterscheiden sich insbesondere auch darin, daß die Fasern mit dem geringen Elastizitäts¬ modul 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.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 .
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 Fa¬ serkugeln, 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 in¬ neres Luftpolster möglichst wenig Wärme durchlassen sol¬ len, andererseits jedoch nicht allzu schwer sein sollen.A fiber ball made from such a mixture of fibers surprisingly has a very large volume and is therefore much more bulky than the known fiber balls. In other words, such a fiber ball has a density that is significantly lower 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. Such fiber balls are therefore 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.
Bevorzugt werden als Fasern mit dem größeren Elasti¬ zitätsmodul solche verwendet, die sich über ihre Länge verjüngen. Diese Fasern weisen somit an ihren jeweiligen Enden unterschiedliche Durchmesser auf. Dadurch liegt in diesen Fasern eine unterschiedliche Elastizität über die Länge dieser Fasern vor. Dies kann sich beim Verarbeiten der Fasern positiv auswirken.The fibers with the larger modulus of elasticity are preferably those which taper over their length. These fibers thus have different diameters at their respective ends. As a result, these fibers have a different elasticity over the length of these fibers. This can have a positive effect when processing the fibers.
Gemäß einer Ausführungsform sind die Fasern mit dem kleineren Elastizitätsmodul gekräuselt, während die Fasern mit dem großen Elastizitätsmodul im wesentlichen ungekräu¬ selt sind.According to one embodiment, the fibers with the smaller modulus of elasticity are crimped, while the fibers with the large modulus of elasticity are essentially uncrimped.
Vorzugsweise sind die Fasern mit dem größeren Elasti¬ zitätsmodul 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, Tier¬ haare od.dgl. oder Synthesefasern, z.B. Polyamid-, Polyester-, Polypropylenfasern od.dgl. mit den jeweiligen Eigenschaften gemäß der Erfindung sein.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, for example cotton or wool fibers, animal hair or the like. or synthetic fibers, for example polyamide, polyester, polypropylene fibers or the like. with the respective properties according to the invention.
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 geför¬ dert.According to a preferred embodiment, 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 improve sleeping comfort.
Die Faserkugeln können nach dem in der EP-A-0.013.427 beschriebenen Verfahren hergestellt werden. The fiber balls can be produced by the method described in EP-A-0.013.427.
