Description

Die Erfindung betrifft ein Textil, insbesondere eine Decke, vorzugsweise Steppdecke, mit einer in einer Hülle eingeschlossenen bauschigen Füllung.The invention relates to a textile, in particular a blanket, preferably quilt, with a bulky filling enclosed in a shell.

Eine der Hauptfunktionen eines Textils, wie z.B. einer Decke, ist deren isolierende Wirkung. Wie bei einer Hose, einer Jacke oder bei einem Schianorak im Winter soll die Isolationswirkung ausreichend sein, um den Körper vor Abkühlung zu schützen. Der eigentliche Isolator ist dabei die Luft. Stand der Technik ist bei Kälteschutzbekleidung und Decken, daß Füllmaterialien, wie Daune, Wolle und Polyester, für einen ausreichend großen Luftpolster sorgen. Ein Nachteil des Einsatzes dieser Materialien im Textilbereich ist, daß Steppdecken wie auch Anoraks sehr dick und voluminös sind. Kann nämlich die eingeschlossene Luft nicht ausreichend immobilisiert werden, kommt es zu Konvektionsphänomenen und somit zu einer Reduktion der isolierenden Wirkung.One of the main functions of a textile, such as a blanket, is its insulating effect. As with a pair of pants, a jacket or a schianorak in winter, the insulation effect should be sufficient to protect the body from cooling. The actual insulator is the air. The prior art is in cold weather protective clothing and blankets that fillers, such as down, wool and polyester, provide a sufficiently large air cushion. A disadvantage of the use of these materials in the textile sector is that quilts as well as anoraks are very thick and voluminous. If the trapped air can not be sufficiently immobilized, convection phenomena occur and thus the insulating effect is reduced.

Der menschliche Körper kontrolliert seinen Wärmehaushalt durch Abgabe von Wasserdampf. Speziell in der Nacht gibt der Körper bei relativ niedriger Körperwärmeproduktion von ca. 85 W immerhin 0,41 Wasserdampf ab. Der Abtransport durch eine Steppdecke oder eine Jacke/Hose etc. ist deswegen so wichtig, weil es sonst zu einem Dampfstau kommen kann. Außerdem werden bei hoher Luftfeuchtigkeit auch die Lebensgrundlagen für Mikroorganismen geschaffen.The human body controls its heat balance by releasing water vapor. Especially at night, the body gives off at least 0.41 water vapor at relatively low body heat production of about 85 W. The removal by a quilt or a jacket / pants, etc. is so important because otherwise it can lead to a stagnation. In addition, the basis of life for microorganisms are created at high humidity.

Somit spielt die Feuchtespeicherung und in weiterer Folge der Feuchtetransport bei der Beurteilung eines Textils, wie einer Decke, eine enorm wichtige Rolle. Gemäß dem Hautmodell (DIN EN 31092 (02/94) bzw. ISO 11092 (10/93)) werden diese Eigenschaften durch beispielsweise den Wasserdampfdurchgangsindex, Kurzzeitwasserdampfaufuahmefähigkeit und Feuchteausgleichskennzahl charakterisiert.Thus, the moisture storage and subsequently the moisture transport in the assessment of a textile, such as a blanket, plays an enormously important role. According to the skin model (DIN EN 31092 (02/94) or ISO 11092 (10/93)), these properties are characterized by, for example, the water vapor transmission index, short-term water vapor absorption capacity and moisture balance characteristic.

Steppdecken haben aufgrund der hohen Anschaffungskosten eine Lebensdauer von etwa 5 bis 10 Jahren. Durch Feuchtigkeitsabgabe des Körpers, Wärme und Substanzen, die im Schweiß und sonstigen flüssigen Ausscheidungen enthalten sind, wird das Wachstum von Kleinorganismen, wie z.B. Milben, begünstigt. Hierdurch können Allergien hervorgerufen werden.Quilts have a lifespan of about 5 to 10 years due to the high initial cost. By moisturizing the body, heat, and substances contained in sweat and other liquid exudates, the growth of small organisms, e.g. Mites, favored. This can cause allergies.

Bisher werden daher waschbare Steppdecken angeboten, die bei 60°C gewaschen werden können. Ein Nachteil dabei ist, daß die meisten Haushalte nicht über eine Waschmaschine mit entsprechendem Füllvolumen verfügen und außerdem die Steppdecke durch das Waschen an Weichheit, Bauschkraft, Form und Anschmiegsamkeit verliert. Die Wirksamkeit des Waschens gegen die Milbenbekämpfung ist außerdem umstritten.So far, therefore, washable quilts are offered, which can be washed at 60 ° C. A disadvantage is that most households do not have a washing machine with a corresponding filling volume and also the quilt by the Washing loses its softness, bulk, shape and softness. The effectiveness of washing against mite control is also controversial.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, einen möglichst dünnen und leichten Wärmeisolator aus Füllfasern und Hüllmaterial zu schaffen, der eine möglichst hohe Feuchteaufnahme- und Feuchtetransportfähigkeit aufweist und welcher aufgrund der Kostenstruktur auch als Einwegtextil eingesetzt werden kann oder vielleicht nur eine Saison, d.h. in etwa ein Jahr, zum Einsatz kommt. Die im Laufe der Zeit sich entwickelnden Mikroorganismenstämme, wie Milben, Pilze oder Bakterien, können mit dem Textil entsorgt werden.The invention aims to avoid these disadvantages and difficulties and has set itself the task of creating a thin and lightweight heat insulator of filling fibers and shell material, which has the highest possible moisture absorption and moisture transportability and which can be used as a disposable textile due to the cost structure or perhaps only one season, ie in about a year, is used. The microorganism strains developing over time, such as mites, fungi or bacteria, can be disposed of with the textile.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausführungsformen sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments are characterized in the subclaims.

Durch das immense Aufkommen von Müll ergibt sich eine enorme Umweltbelastung. Isolierende Textilien, wie Steppdecken etc., werden derzeit hauptsächlich mit Polyester, Daune oder Wolle gefüllt bzw. sind in einen Stoff eingehüllt, der entweder aus 100 % Baumwolle, 100 % Polyester oder Mischungen daraus besteht. Ein Recycling dieser Rohstoffe stellt sich als ausgesprochen schwierig dar.Due to the immense amount of waste, there is an enormous environmental impact. Insulating textiles, such as quilts, etc., are currently mainly filled with polyester, down or wool or are wrapped in a fabric that consists of either 100% cotton, 100% polyester or blends thereof. Recycling these raw materials is extremely difficult.

Isolierende Textilien gemäß dem einleitenden Teil der Beschreibung werden bisher primär aus gewebten und gestrickten Stoffen hergestellt, die sehr teuer und aufwendig sind. Dabei wird ein Garn aus Stapelfasern - beispielsweise mittels Ring- oder Rotorspinnverfahren - oder mittels eines Filamentgarnes zu einem Stoff verwebt oder verstrickt. Die Farbgebung des Gebildes kann dabei vor oder nach dem Spinnen, Stricken oder Weben erfolgen. Für die Herstellung eines Kleidungsstückes oder textilen Gebildes (beispielsweise einer Steppdecke) werden Compositkonstruktionen aus Webstoffen und Nonwovens (beispielsweise ein kardiertes Vlies) eingesetzt.Insulating textiles according to the introductory part of the description are so far primarily made of woven and knitted fabrics, which are very expensive and expensive. In this case, a yarn of staple fibers - for example by means of ring or rotor spinning process - or by means of a filament yarn is woven into a fabric or entangled. The coloring of the structure can be done before or after spinning, knitting or weaving. For the production of a garment or textile structure (for example a quilt) composite constructions of woven and nonwovens (for example a carded nonwoven) are used.

Der Einsatz von Nonwovens im Bekleidungs- und Heimtextilbereich ist bekannt. Diese Artikel haben jedoch den Nachteil, daß sie bisher nur aus Synthesefasern hergestellt wurden. Eine 100 % Cellulosefaser (beispielsweise aus Viskose) war bisher nicht möglich, da Viskose einen Mangel an Festigkeit aufweist. Der Gebrauch ist dadurch eingeschränkt.The use of nonwovens in the clothing and home textile sector is well known. However, these articles have the disadvantage that they were previously made only of synthetic fibers. A 100% cellulose fiber (for example made of viscose) was previously not possible because viscose has a lack of strength. The use is limited.

Der Einsatz von Nonwovens für Bekleidung ist bekannt aus der EP 1 031 653 The use of nonwovens for clothing is known from the EP 1 031 653

Überraschenderweise wurde gefunden, daß Lyocell in entsprechender Faserfeinheit mittels spunlace Technologie hergestellt textile Flächen ergibt, die jenen gewebter Textilien sehr ähnlich sind. Sie weisen eine

  • hohe Festigkeitn sowie
  • hinreichende Weichheit auf und stellen einen
  • großen Feuchtigkeitstransport sicher.
Surprisingly, it has been found that Lyocell produced in appropriate fiber fineness by spunlace technology results in textile surfaces that are very similar to those woven textiles. You have one
  • high strength as well
  • sufficient softness and provide one
  • great moisture transport safely.

Überraschenderweise wurde auch gefunden, daß die Flächengewichte dieser Nonwovens bis zu 20 g/m2 hergestellt werden können und dabei bei weitem unter jenen von traditionellen, d.h. Webstoffen für einen vergleichbaren Einsatz (normalerweise bei 90 bis 100 g/m2), liegen. D.h. es kann mit wenig Fasereinsatz ein Textil hergestellt werden und dies bei überschaubaren Kosten. Feinste traditionelle Gewebe können nur mit sehr hohem Aufwand, d.h. unter Einsatz von feinsten, teuersten Garnen und bei produktivitätsarmen Webeinstellungen, hergestellt werden.Surprisingly, it has also been found that the basis weights of these nonwovens can be made up to 20 g / m 2 and are well below those of traditional, ie, woven fabrics for comparable use (normally 90 to 100 g / m 2 ). That is, it can be made with little fiber use a textile and this at a manageable cost. Finest traditional fabrics can only be produced at great expense, ie using the finest, most expensive yarns and low productivity weaving settings.

Die Erfindung ist nachfolgend anhand einiger Ausführungsbeispiele näher erläutert. Fig. 1 der Zeichnung veranschaulicht eine Steppdecke in Ansicht, Fig. 2 im Schitt gemäß der Linie II-II.The invention is explained in more detail with reference to some embodiments. Fig. 1 the drawing illustrates a quilt in view, Fig. 2 in the section according to the line II-II.

Eine Steppdecke der erfindungsgemäßen Art ist von Lyocellfasern gebildet. Die Hülle 1 ist ein spunlace nonwoven Vlies aus beispielsweise 0,9 dtex mit einem Flächengewicht von 40 g/m2. Die Füllung 2 ist ein Hochbauschvlies aus Lyocellfasern mit z.B. 6,7 dtex, die kardiert und gekrempelt wurden. Die Länge der Lyocellfasern für die Füllung liegt bei 40 bis 70 mm, für die Hülle zwischen 30 und 40 mm. Für die Füllung könnten auch Faserbällchen aus diesen beschriebenen Lyocellfasem zum Einsatz kommen.A quilt of the type according to the invention is formed by lyocell fibers. The shell 1 is a spunlace nonwoven web of, for example, 0.9 dtex with a basis weight of 40 g / m 2 . The filling 2 is a Hochbauschvlies of lyocell fibers with eg 6.7 dtex, which were carded and carded. The length of the lyocell fibers for the filling is 40 to 70 mm, for the shell between 30 and 40 mm. For the filling and fiber balls could be used from these described Lyocellfasem.

In nachstehender Tabelle sind unterschiedliche Füllungen in jeweils gleichen Baumwollhüllen hinsichtlich ihrer Eigenschaften untereinander verglichen, wobei die physiologischen Daten gemäß dem Hauptmodell gemäß DIN EN 31092 (02/94) bestimmt wurden. Es handelt sich um die Rct-Werte. Tabelle I Muster Füllung d mm F g/m2 Rct 103 m2k/W Rct/d 103 (m2k/W)/mm 1 Lyocell 6,7 dtex 30 550 757 25,2 3 50 % Lyocell/50 % Polyester 25 286 575 23,0 2 Wolle 35 466 754 21,5 5 Daune 75 468 1434 19,1 4 Polyester 50 378 791 15,8 In the table below, different fillings in the same cotton sheaths are compared in terms of their properties with each other, the physiological data according to the main model according to DIN EN 31092 (02/94) were determined. These are the Rct values. Table I template filling d mm F g / m 2 Rct 10 3 m 2 k / W Rct / d 10 3 (m 2 k / W) / mm 1 Lyocell 6.7 dtex 30 550 757 25.2 3 50% lyocell / 50% polyester 25 286 575 23.0 2 Wool 35 466 754 21.5 5 down feather 75 468 1434 19.1 4 polyester 50 378 791 15.8

Aus dieser Tabelle ist erkennbar, daß Lyocellfasern mit 6,7 dtex (Muster 1) bezogen auf die Dicke die besten und Polyester (Muster 4) die schlechtesten Isolierwerte erbringen. Durch die Zumischung von Polyester zu Lyocell (Muster 3: 50 %/50 %) verschlechtert sich der Isolierwert proportional. 100 % Daune (Muster 5) und Wolle (Muster 2) schneiden schlechter ab als eine solche Mischung (Muster 3).From this table it can be seen that lyocell fibers of 6.7 dtex (Sample 1) provide the best insulation in terms of thickness and the worst in polyester (Sample 4). By adding polyester to lyocell (Sample 3: 50% / 50%), the insulation value deteriorates proportionally. 100% down (pattern 5) and wool (pattern 2) perform worse than one (pattern 3).

Die Isolierwerte gemäß Tabelle I sind in Fig. 3 graphisch veranschaulicht.The insulation values according to Table I are in Fig. 3 graphically illustrated.

In der nachstehenden Tabelle II sind die Muster 1, 4 und 5 der Tabelle I mit Füllungen, gebildet aus Lyocell-Microfaser, also einer Lyocellfaser mit einem Titer unter 1,0 dtex, verglichen. Die Werte der Muster 1, 6 und 7 sind in Fig. 4 graphisch dargestellt.

The values of patterns 1, 6 and 7 are in Fig. 4 shown graphically. Table II template filling d mm F g / m 2 Rct 10 3 m 2 k / W Rct / d 10 3 (m 2 k / W) / mm 1 Lyocell 6.7 dtex 30 550 757 25.2 4 polyester 50 378 791 15.8 5 50% lyocell / 50% polyester 25 286 575 23.0 6 Lyocell MICRO 15 204 457 30.5 7 Lyocell MICRO / polyester 30 278 725 24.2

Durch den Einsatz von Lyocell-Microfasem können die schon hervorragenden Isolationswerte noch weiter verbessert werden.The use of Lyocell microfibres can further improve the already excellent insulation values.

In nachstehender Tabelle III sind Steppdecken unterschiedlicher Hüllen und Füllungen miteinander verglichen, wobei die Steppdeckenhöhen jeweils so gewählt wurden, daß die unterschiedlichen Steppdecken gleiche Isolationswerte aufweisen. Tabelle III Hülle Füllung Steppdeckenhöhe [mm] Baumwollgewebe Daune 75 Baumwollgewebe 6,7 dtex Lyocell 47 Nonwovens aus 0,9 dtex Lyocell 40 g/m2 6,7 dtex Lyocell 33 Nonwovens aus 0,9 dtex Lyocell 40 g/m2 0,9 dtex Lyocell 28 In Table III below, quilts of different sheaths and fillings are compared with each other, wherein the quilt heights were each chosen so that the different quilts have the same insulation values.

Es ist zu erkennen, daß die beiden in der Tabelle letztgereihten Steppdecken bei gleicher Isolationsleistung bedeutend dünner sind als Daune mit Baumwollgewebe oder Baumwollgewebe mit Lyocellfüllung. Die dünnste Steppdecke ist von Lyocell-Microfaser sowohl für die Hülle als auch für die Füllung gebildet.It can be seen that the two quilts last in the table are significantly thinner with the same insulation performance than down with cotton fabric or cotton fabric with Lyocell filling. The thinnest quilt is made of lyocell microfiber for both the cover and the filling.

In Fig. 5 sind die Steppdeckendicken der in Tabelle III aufgelisteten Steppdecken graphisch veranschaulicht.In Fig. 5 For example, the quilt thicknesses of the quilts listed in Table III are graphically illustrated.

Werden schon mit Lyocell als Füllfaser in der Baumwollhülle gute Werte für den Wasserdampfdurchgangsindex erzielt, können diese durch den Einsatz eines Lyocell Satingewebes um 22 % verbessert werden. Mit einem Lyocell spunlace-nonwoven Vlies erhöht sich der Wert überraschenderweise um 36 % und mit Lyocell Micro als Füllfaser erzielt man den Spitzenwert, nämlich eine 50 %ige Steigerung.If good values for the moisture vapor transmission index are achieved with Lyocell as filling fiber in the cotton casing, these can be improved by 22% by using a Lyocell satin weave. With a Lyocell spunlace nonwoven fleece the value surprisingly increases by 36% and with Lyocell Micro as the filler fiber, the peak value is achieved, namely a 50% increase.

Überraschenderweise hat sich gezeigt, daß durch den Einsatz von nonwoven Hüllen phantastische Wasserdampfdurchgangs-Indexwerte erzielt werden können.Surprisingly, it has been shown that fantastic water vapor transmission index values can be achieved by using nonwoven casings.

Die Erfindung läßt sich für alle Textilien anwenden, bei denen eine isolierende Wirkung bei hohem Feuchtigkeitstransport und Leichtheit verlangt wird, wie z.B. Bettwaren aller Art, Steppdecken, Kissen, Polster, Matratzenauflagen, sowie für Bekleidungen, wie Jacken und Hosen, Überhosen, Anoraks etc. Die Füllungen können von kardierten Vliesen, aber auch von Faserbällchen aus Lyocell oder Mischungen daraus oder auch als kostengünstige Variante aus lose eingebrachten, z.B. in die Hülle eingeblasenen Lyocellfasern gebildet sein. Für spezielle Einsatzgebiete können für die Füllung die Lyocellfasern gemischt werden mit Daunen und/oder Polymilchsäurefasern und/oder Celluloseacetatfasern und/oder Sojabohnenfasern.The invention can be applied to all textiles in which an insulating effect with high moisture transport and lightness is required, such as e.g. Bedding of all kinds, quilts, pillows, upholstery, mattress pads, as well as for clothing, such as jackets and pants, pants, anoraks etc. The fillings can be made of carded webs, but also of fiber balls of lyocell or mixtures thereof or as a cost-effective variant of loosely introduced , eg be formed in the shell blown Lyocell fibers. For special applications, the lyocell fibers can be mixed with down and / or polylactic acid fibers and / or cellulose acetate fibers and / or soybean fibers for the filling.

Weiters kann die Hülle aus einem Mehrschichtvlies zur Erhöhung seiner Festigkeit bestehen.Furthermore, the sheath may consist of a multi-layer non-woven to increase its strength.
