Entsprechend einer besonders bevorzugten Ausführungsform des Gegenstandes der Erfindung kennzeichnet sich das Vlies dadurch, dass es als homogenes Vlies aus groben Fasern mit einer Garnfeinheit von ca. 3,3 dtex, aus Fasern mittlerer Durchmesser zwischen 2,2 dtex bis 1,7 dtex oder aus Fasern mit kleinen und ganz kleinen Durchmessern, sogenannten Mikrofasern, mit 1,0 dtex bis 0,6 dtex besteht.According to a particularly preferred embodiment of the subject matter of the invention, the nonwoven is characterized by being a homogeneous web of coarse fibers having a yarn count of about 3.3 dtex, of fibers of mean diameter between 2.2 dtex to 1.7 dtex or of Fibers with small and very small diameters, so-called microfibers, consisting of 1.0 dtex to 0.6 dtex.
Schallversuche im Kundtschen Rohr haben nachgewiesen, dass die 0,6 dtex-Fasern besonders gut Schall absorbieren, insbesondere im Frequenzbereich über 6000 Hz.Sound tests in Kundt's tube have proven that the 0.6 dtex fibers absorb sound particularly well, especially in the frequency range above 6000 Hz.
Das erfinderische Schallisoliervlies kann vorteilhafterweise entweder geschichtet ausgebildet sein und seine feineren Fasern in Richtung einer Schallquelle oder mehrere Lagen von Vliesen aus Fasern jeweils verschiedener Faserdurchmesser übereinander angeordnet sein.The inventive Schallisoliervlies may advantageously be either layered and its finer fibers in the direction of a sound source or multiple layers of webs of fibers each having different fiber diameters are arranged one above the other.
Des Weiteren kann ein Schallisoliervlies entweder als homogenes Schallisoliervlies aus Fasern mit allen auf dem Markt erhältlichen Durchmessern bestehen oder aus Fasern einer bestimmten Auswahl einer vorbestimmten Sieblinie, die den vorhandenen zu absorbierenden oder abzudämpfenden Frequenzen angepasst ist.Furthermore, a sound-insulating fleece may consist of either a homogeneous sound-insulating fleece of fibers of all diameters available on the market, or of fibers of a certain selection of a predetermined grading curve adapted to the existing frequencies to be absorbed or dampened.
Vorzugsweise ist das Schallisoliervlies in einen Fireblocker, wie etwa ein schwer entflammbares Gewebe aus Aramiden eingehüllt, kaschiert oder verklebt, versteppt oder vernäht, wobei auch dieses Gewebe mit seinen schalltechnischen Eigenschaften auf die abzudämmenden Schallspektren abgestimmt ist.Preferably, the Schallisoliervlies is wrapped in a fireblocker, such as a flame retardant fabric of aramids, laminated or glued, quilted or sewn, and this fabric is tuned with its sonic properties on the sound spectra to be isolated.
Vorteilhaft ist des Weiteren, dass das Schallisoliervlies in eine gas- und/oder feuchtigkeitsabhaltende Folie, etwa gegen Wasser, Wasserdampf, Hydrauliköle, Treibstoffe oder deren Dämpfe, eingepackt, etwa eingeklebt, eingenäht oder eingeschweißt und/oder auch zusätzlich mit anderen Textilen, etwa in der Luftfahrt oder militärisch zugelassenen Deckgeweben versehen ist. Die gas- und/oder feuchtigkeitsabhaltende Folie kann dabei durch das Aufkleben eines Gewebes, Vlieses oder durch eine Faserbesprühung verstärkt sein, wobei die gas- und/oder feuchtigkeitsabhaltende Folie mittels lösemittelhaltigem Sprüh-Klebstoff oder Sprüh-Klebstoff auf Wasserbasis oder mit einer oder mehreren Lagen Schmelzkleber verklebt sein kann. Auch die Deckgewebe können mit dem Schallisoliervlies verklebt, vernäht, gesteppt oder verschweißt oder auch über Polsterknöpfe damit verbunden sein.It is also advantageous that the Schallisoliervlies in a gas and / or moisture-preventing film, such as water, steam, hydraulic oils, fuels or their vapors, wrapped, glued, sewn or welded and / or also with other textiles, such as in aviation or military approved cover fabrics. The gas and / or moisture-preventing film can be reinforced by the gluing of a fabric, non-woven or by a fiber spray, wherein the gas and / or moisture-preventing film by means of solvent-based spray adhesive or water-based spray adhesive or with one or more layers Hot melt adhesive can be glued. Also, the cover fabrics can be glued to the Schallisoliervlies, sewn, quilted or welded or connected via cushion buttons with it.
Gemäß eine besonders bevorzugten Ausführungsform des Gegenstandes der Erfindung ist das Isoliervlies bezogen auf eine größere Isolierfläche, etwa auf einem Flugzeuginnenraum, sektional unterschiedlich ausgebildet und einem örtlich auftretenden Schallereignis gegenüber mit einem örtlich angepassten Schallabsorptions- und -dämmverhalten ausgestattet.According to a particularly preferred embodiment of the subject matter of the invention, the insulating fleece is formed differently with respect to a larger insulating surface, for example on an aircraft interior, and equipped with a locally adapted sound event with a locally adapted sound absorption and insulation behavior.
Seine von außen sichtbaren Flächen können dabei vorzugsweise mit einer gleichförmigen homogenen Oberflächenstruktur und Ansicht ausgerüstet.His visible from the outside surfaces can preferably equipped with a uniform homogeneous surface structure and view.
Das erfinderische Schallisoliervlies kann mit zusätzlichen Isolierschaumplatten zu Isolierpaketen kombiniert sein oder auch zu mehreren Lagen von Vliesen und Schaumplatten hintereinander angeordnet, zu einem gekoppelten Schwinger ausgebildet sein.The inventive Schallisoliervlies can be combined with additional insulating foam plates to Isolierpaketen or arranged to several layers of nonwovens and foam sheets in a row, be formed into a coupled oscillator.
Die Fasern des Schallisoliervlieses bestehen vorzugsweise aus Polyimidfasern, dem Fasern mit hoher Rückverformung beigemischt sein können, wobei es alleine oder auch zwischen Geweben, Folien und anderen Vliesen oder beschichteten Geweben zum Teil definiert zusammengedrückt bzw. verdichtet ist, um etwa quasi vorgespannt zu sein, was sich schalltechnisch besonders wirkungsvoll auf die Dämmung auswirkt.The fibers of the sound insulating web are preferably made of polyimide fibers which may be blended with high recovery fibers, whether alone or between fabrics, films and other webs or coated webs partially defined compressed or compressed to be more or less biased, which has a particularly effective sound effect on the insulation.
Insbesondere lassen sich mit dem erfinderischen Schallisoliervlies trotz hoher Schallisolierleistungen auch Dämmungen erzeugen, die bei Bedarf nur wenig wärmeisolierend ausgeführt sein können, wenn dies gewünscht ist.In particular, with the inventive Schallisoliervlies despite high Schallisolierleistungen also produce insulation that can be performed only slightly heat-insulating if desired, if desired.
Die Deckgewebe oder Deckschichten des Schallisoliervlieses können aus Naturfasern, Aramiden, Glasgeweben, Keramikgeweben oder Kunststofffasern, wie Polyimidfasern, bestehen.The cover fabrics or cover layers of the Schallisoliervlieses may consist of natural fibers, aramids, glass fabrics, ceramic fabrics or plastic fibers, such as polyimide fibers.
Des Weiteren kann es mit silikonhaltigen Mitteln oder Fluorocarbon-Verbindungen oder anderen bekannten Imprägnier- oder Tränkungsmitteln imprägniert oder hydrophobiert oder auch oleophobiert sein.Furthermore, it may be impregnated with silicone-containing agents or fluorocarbon compounds or other known impregnating or impregnating agents or hydrophobicized or else oleophobed.
Um eine übermäßige Aufnahme des Schallisoliervlieses von Wasser zu verhindern, können zwischen einzelnen Schichten solcher erfinderischen Vliese Folien eingebracht sein.In order to prevent excessive absorption of the Schallisoliervlieses of water, can be introduced between individual layers of such inventive nonwoven films.
Das erfinderische Schallisoliervlies lässt sich nicht nur in Flugzeugen, sondern auch auf Schiffen, in Hubschraubern, Bussen, Yachten, Militärfahrzeugen, Lokomotiven, Eisenbahnwaggons oder sonstigen Radfahrzeugen wie Baustellenfahrzeugen, Radpanzern oder in festen Bauwerken vorteilhaft verwenden, natürlich überall da, wo eine erhöhte Schallisolation gewünscht ist, insbesondere wenn spezielle Geräuschfrequenzen abgedämmt oder absorbiert werden sollen.The inventive Schallisoliervlies can be used not only in airplanes, but also on ships, in helicopters, buses, yachts, military vehicles, locomotives, railway cars or other vehicles such as construction vehicles, wheeled armor or solid structures advantageous, of course, wherever an increased sound insulation desired is, especially when special noise frequencies are to be dammed or absorbed.
Das Verfahren zur seiner Herstellung erfolgt dadurch, dass Fasern mit vorbestimmten Durchmessern, Querschnittsformen und Faserlängen mit einem Anteil Schmelzfasern vermischt werden, diese Mischung auf einer Karde/Krempel oder in einer andern bekannten Vorrichtung zu einem Vlies verarbeitet wird, welches anschließend durch eine Wärmezufuhr mit einem Anschmelzen der Schmelzfasern räumlich zu einem Isoliervlies verbunden wird, wobei als Schmelzfasern bevorzugt zweikomponentige Schmelzfasern verwandt werden.The process for its production takes place in that fibers with predetermined diameters, cross-sectional shapes and fiber lengths are mixed with a proportion of melt fibers, this mixture is processed on a card / carding machine or in another known device to a nonwoven, which is then by a heat with a Melting of the melt fibers is spatially connected to a Isoliervlies, being used as melt fibers preferably two-component melt fibers.
Das erfinderische Isoliervlies wird insbesondere nach einer Analyse von in einem Raum vorhandenen Geräuschen entsprechend deren Intensität und Frequenz ausgesucht und verbaut, wobei das Schallisoliervlies gegebenenfalls nicht nur hinsichtlich seiner Intensität und Frequenz ausgesucht wird, sondern auch in Abhängigkeit eines gewünschten Wärmedurchgangswertes, so dass dann ein in seiner Dichte angepasstes Isoliervlies zur Anwendung kommt.The inventive insulating fleece is selected and installed in particular according to an analysis of existing in a room noise according to their intensity and frequency, the Schallisoliervlies is optionally selected not only in terms of its intensity and frequency, but also in response to a desired heat transfer value, so that then a in its density adapted insulating fleece is used.
Bei einem Versuch wurden 0,6 dtex und 2,2 dtex Fasern mit jeweils ca. 5% Schmelzfasern zu Vliesen kardiert, diese Vliese durch einen Ofen geschickt, um die Schmelzfaser aufzuschmelzen und die Polyimidfasern an ihren Berührungsstelle zu verkleben. Der Absorptionskoeffizient der dickeren Faser betrug bei 2000 Hz 0,31, bei 3000 Hz 0,97, bei 4000 Hz 0,76, bei 5000 Hz 0,44 und bei 6000 Hz 0,84, wobei der Absorptionskoeffizient des Vlieses mit der dünneren Faser bei 2000 Hz 0,17, bei 3000 Hz 0,60, bei 4000 Hz 0,71, bei 5000 Hz 0,48 und bei 6000 Hz 0,92 betrug. Das Schallisoliervlies aus der dünneren Polyimidfasern isoliert ab einem Frequenzbereich von etwa 4500 Hz also bereits deutlich besser den Schall als das Vlies aus dem dickeren Material.In one experiment, 0.6 dtex and 2.2 dtex fibers each with about 5% melt fibers were carded into nonwovens, these nonwovens were passed through an oven to melt the melt fiber and bond the polyimide fibers to their point of contact. The absorption coefficient of the thicker fiber was 0.21 at 2000 Hz, 0.97 at 3000 Hz, 0.76 at 4000 Hz, 0.44 at 5000 Hz and 0.84 at 6000 Hz, the absorption coefficient of the thinner fiber nonwoven was 0.17 at 2000 Hz, 0.60 at 3000 Hz, 0.71 at 4000 Hz, 0.48 at 5000 Hz and 0.92 at 6000 Hz.
