The inventive mixed fiber fleece or fabric provides further optimized moisture management compared with previously known mixed fiber fleece while having an antibacterial effect and ensuring house mite-free conditions without using chemicals and also being 100 percent biodegradable, which is achieved by the fact that the main components of the mixed fiber fleece or fabric are cellulose fibers and kapok fibers.

Description

Mischfαservl ies od er -gewebe Mixed fabrics or fabrics
Die Erfindung betrifft ein Mischfαservlies oder -gewebe zur Herstellung von Nonwoven- oder Woven-Artikeln wie Füllungen von Bet wαren, Polstermöbeln und Automobilinterieur oder wie von deren Bezügen, textilen Kleidungsstücken und Futterstoffen.The invention relates to a mixed non-woven fabric or woven fabric for the production of nonwoven or woven articles such as fillings of bed wares, upholstered furniture and automobile interiors or of their covers, textile articles of clothing and lining materials.
Es ist ein Mischfαservliese aus Schafschurwolle und Kapokfasern bekannt, DE 40 30 1 72 C2, das als reines Naturprodukt vor allem den hygienischen Bedürfnissen, nicht zuletzt von Krankenhäusern, Laboreinrichtungen und Pflegeheimen Rechnung trägt, da durch den Bestandteil an Kapokfasern eine antibakterielle und fäulnishemmende Eigenschaft in ein solches Mischfaservlies eingetragen wird.A mixed fiber nonwoven made of sheep's wool and kapok fibers is known, DE 40 30 1 72 C2, which, as a pure natural product, primarily takes hygienic requirements into account, not least from hospitals, laboratory facilities and nursing homes, since the component on kapok fibers has an antibacterial and antifouling property in such a mixed fiber fleece is registered.
Aufgabe der Erfindung ist es, ein Mischfaservlies oder -gewebe zur Verfügung zu stellen, welches gegenüber dem bekannten Mischfaservlies ein weiter optimiertes Feuchtigkeitsmanagement bietet und dabei ohne Einsatz von Chemie antibakteriell wirkt, eine Hausstaubmilbenfreiheit gewährleistet und dabei 100% biologisch abbaubgr ist.The object of the invention is to provide a mixed fiber fleece or fabric which, compared to the known mixed fiber fleece, offers a further optimized moisture management and has an antibacterial effect without the use of chemicals, ensures freedom from dust mites and is 100% biodegradable.
Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Merkmalen des Oberbegriffs des Hauptanspruchs erfindungsgemäß aus den Merkmalen des kennzeichnenden Teils des Hauptanspruchs. Das Mischfaservlies oder das Mischfasergewebe besteht dazu aus den Hauptbestandteilen Zellulosefasern und Kapokfasern, sodass durch den Anteil an Kapokfasern sichergestellt ist, dass ein aus einem solchen Mischfaservlies oder Mischfasergewebe hergestellter Gegenstand ohne aufwändige Reinigung oder Waschvorgänge dauerhaft hausstaubmil- benfrei und bakterienfrei bleibt. Da beide Komponenten aus nachwachsenden pflanzlichen Rohstoffen bestehen, wird ein reines, leicht biologisch abbaubares und verrottbares Naturprodukt zur Verfügung gestellt, welches des Weiteren in besonders vorteilhafter Art und Weise als Klima- Vlies fungiert. Je nach Temperaturdifferenz zwischen einer Wärmequelle wie etwa der Körperwärme eines Schläfers unter dem Vlies und einer von kalt nach warm steigenden Außentemperatur über dem Vlies ergibt sich unter Verwendung des erfinderischen Materials eine Verschiebung seiner Wirkung von "zunächst wärmend ' über " mehr Wärme abführend ' bis hin zu einer " Isolationswirkung gegen Wärme .This object is achieved in connection with the features of the preamble of the main claim according to the invention from the features of the characterizing part of the main claim. For this purpose, the mixed fiber fleece or the mixed fiber fabric consists of the main constituents cellulose fibers and kapok fibers, so that the proportion of kapok fibers ensures that an object made from such a mixed fiber fleece or mixed fiber fabric remains permanently free of dust mites and bacteria-free without complex cleaning or washing processes. Since both components consist of renewable vegetable raw materials, a pure, easily biodegradable and rotten natural product is made available, which also functions in a particularly advantageous manner as a climate fleece. Depending on the temperature difference between a heat source such as the body heat of a sleeper under the fleece and a cold to warm outside temperature above the fleece, the use of the inventive material results in a shift in its effect from "initially warming" to "more heat-dissipating" to to an "insulation effect against heat.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject matter of the invention result with and in combination from the following subclaims.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung werden für die Zellulosefasern industriell auf chemischem Weg hergestellte Zellulosefasern oder Zellulose-Regenrat-Fasern wie etwa Viskose, Modal oder andere verwandt, da diese Eigenschaften aufweisen können, die denen von natürlichen Zellulosefasern zum Teil deutlich überlegen sind.According to a particularly advantageous embodiment of the invention, cellulose fibers or cellulose regeneration fibers such as viscose, modal or others which are manufactured industrially by chemical means are used for the cellulose fibers, since these can have properties which are in some cases significantly superior to those of natural cellulose fibers.
Bei einer besonders vorteilhaften Ausführungsform des Gegenstandes der Erfindung bestehen die Zellulosefasern aus nach dem Lösemittelver- fahren hergestellten Lyocellfasern, die nachweislich ein optimiertes Feuchtigkeitsmanagement gegenüber Schafschurwolle aufweisen, insbesondere eine bessere Feuchtigkeitsaufnahme und einen besseren Feuchtigkeitsausgleich gewährleisten, sowie eine größere Atmungsaktivität be- sitzen. Ein weiterer Vorteil der Lyocellfasern ist deren hohe Nassfestigkeit, die etwa 20 % über der von Viskose liegt und zusätzlich die große Feinheit, mit der die Lyocellfasern hergestellt werden können.In a particularly advantageous embodiment of the subject of the invention, the cellulose fibers consist of after the solvent drive manufactured Lyocell fibers that have been proven to have optimized moisture management compared to new wool, in particular ensure better moisture absorption and better moisture balance, and have greater breathability. Another advantage of the Lyocell fibers is their high wet strength, which is about 20% higher than that of viscose and in addition the great fineness with which the Lyocell fibers can be produced.
Da sich solche Lyocellfasern zu Vliesen oder auch zu Geweben verarbei- ten lassen, wird in Verbindung mit den Kapokfasern ein weiter zu verarbeitendes Ausgangsprodukt zur Verfügung gestellt, welches gegenüber bekannten Mischfaservliesen oder -geweben deutliche technische Vorteile aufweist und dabei durch den Kapokfaseranteil auch ohne Reinigung oder Nasswäsche antibakteriell und hausstaubmilbenfrei bleibt und des Weiteren 100 % biologisch abbaubar ist.Since such lyocell fibers can be processed into nonwovens or also into fabrics, in connection with the kapok fibers a further product to be processed is made available, which has clear technical advantages over known mixed fiber nonwovens or woven fabrics and, due to the kapok fiber content, also without cleaning or Wet laundry remains antibacterial and free of dust mites and is also 100% biodegradable.
Durch die Verwendung der Lyocellfaser in einem Mischfaservlies oder - gewebe ergeben sich neben den technischen Vorteilen auch andere, etwa physiologische, etwa wenn ein solches Vlies für Bettdecken Verwen- düng findet, unter denen sich durch eine neuartige Resonanzwärmereflexion ein "sofort-warm-Effekt" und damit ein subjektives Wohlgefühl einstellt. Das neue Mischfaservlies stellt demnach ein neuartiges Klimavlies dar. Dies wird dadurch erreicht, dass das stark hydrophile Verhalten von Lyocell plus Luftvolumen über Bausch vermischt mit Kapok und dessen hohem Isolationsverhalten in Verbindung mit der Körperwärme eines Nutzers als Wärmequelle diese physikalische Reaktion einer Resonanzwärmereflexion hervorruft. Das Vlies gibt die ausgestrahlte Wärme sofort in einer Resonanzreaktion an die Wärmequelle zurück, wobei der spür- bare Effekt mit Feuchtwärme subjektiv noch höher ist.By using the Lyocell fiber in a mixed fiber fleece or fabric, there are other technical advantages as well, such as physiological ones, such as when such a fleece is used for duvets, among which there is an "instant warm effect" due to a novel resonance heat reflection. and thus a subjective feeling of wellbeing. The new mixed fiber fleece is therefore a new type of climate fleece. This is achieved in that the highly hydrophilic behavior of Lyocell plus air volume over bulk mixed with Kapok and its high insulation behavior in connection with the body heat of a user as a heat source causes this physical reaction of resonance heat reflection. The fleece immediately returns the radiated heat to the heat source in a resonance reaction, whereby the bare effect with moist heat is subjectively even higher.
Durch die Mischung von hydrophilen Lyocellanteilen und den hydrophoben Kapokanteilen entsteht bei Anwesenheit einer Wärmequelle, wie et- wa der Körperwärme eines Schläfers, ein einmaliger Klima-Effekt, der zu einer Luftschichten-Bewegung (Wind) im Vlies führt. Feuchtwarme Körperausdünstungen werden beispielsweise auf Grund des hohen relativen Wasserdampftransportvermögens von Lyocell schnell in Richtung des kälteren Schlafraums mit niedrigerer Luftfeuchte abgegeben, was vom hydrophoben Kapokanteil wesentlich beschleunigt wird. Diese schnelle Abtrocknung der Lyocell-Komponente unterstützt die durch das Kapok gewonnenen Eigenschaften, die das Material so bakterien- und milbenfrei halten, sodass es für Hausstauballergiker besonders gut geeignet ist, da sie die den Bakterienkulturen und auch den Hausstaubmilben die zum Wachsen benötigte Feuchte entzieht.The mixture of hydrophilic lyocell parts and the hydrophobic kapokan parts creates a unique climate effect in the presence of a heat source, such as the body heat of a sleeper, which leads to an air layer movement (wind) in the fleece. Moist warm body exhalations, for example due to the high relative water vapor transport capacity of Lyocell, are quickly released in the direction of the colder bedroom with lower air humidity, which is significantly accelerated by the hydrophobic kapok component. This quick drying of the Lyocell component supports the properties obtained by the Kapok, which keep the material so free of bacteria and mites that it is particularly suitable for people with house dust allergies, as it removes the moisture required for the bacterial cultures and also the house dust mites to grow.
Kurzzeitig kann jedoch auch bei vermehrter Schweißabgabe eines Schläfers die Feuchtigkeit aufgenommen und gepuffert werden, wobei punk- tuell auftretende Feuchtigkeit auf größere Flächen des Vlies verteilt wird, sodass sich quasi eine Löschblatt-Funktion ergibt.For a short time, however, the moisture can be absorbed and buffered even if more sleep is given off by a sleeper, with the point of the occurrence of moisture that is distributed over larger areas of the fleece, so that there is a quenching sheet function.
Insgesamt ergibt sich im Verhältnis von der Körpertemperatur eines Schläfers in einem kalten Raum zu der in einem warmen Raum eine Verschiebung der Funktionsleistung des Mischfaservlieses von zunächst so- fort wärmend über zu starke Wärme abführend bis hin zur Isolation gegen zu starke Wärme von außen, was subjektiv kühlend wirkt. Die einzelnen zu monogamen Vliesen verarbeiteten Komponenten erzeugen keine weiteren Funktionen als die bekannten, die homogene Mischung der beiden Naturstoffe erbringt dagegen jedoch Funktionen, die in Bezug auf Isolation, Hygroskopie und Verbrauchernutzen eine ganz besondere Wirkung als Klima-Vlies entfalten und zwar einfach, genial und natürlich.Overall, in relation to the body temperature of a sleeper in a cold room to that in a warm room, there is a shift in the functional performance of the mixed fiber fleece from immediately warming to excessive heat dissipation to insulation against excessive heat from outside, which is subjective has a cooling effect. The individual components processed to monogamous nonwovens do not produce any further functions than the known ones, but the homogeneous mixture of the two natural materials, however, provides functions that have a very special effect as a climate nonwoven in terms of insulation, hygroscopy and consumer benefits, namely simple, brilliant and Naturally.
Da die Lyocellfasern, insbesondere aber auch die Kapokfasern, keine sehr große Bauschkraft besitzen, ist es gemäß einer weiteren Ausbildung der Erfindung möglich, dem Mischfaservlies aus Zellulosefasern, insbesondere Lyocellfasern und Kapokfasern zusätzlich Polyesterfasern beizufügen, um den Bausch dauerhaft zu verbessern. Since the lyocell fibers, but especially also the kapok fibers, do not have a very high bulk, it is possible according to a further embodiment of the invention to additionally add polyester fibers to the mixed fiber fleece composed of cellulose fibers, in particular lyocell fibers and kapok fibers, in order to permanently improve the bulk.
