"Wirrvlies und Verfahren zu dessen Herstellung""Tangled fleece and process for its production"
Die Erfindung betrifft ein Wirrvlies und ein .Verfahren zum Herstellen eines derartigen Wirrvlieses aus endlosen Fäden oder Fasern, die zur Vliesbildung vorzugsxieise auf einem unter Saugzug stehenden Sieb, vorzugsweise einer Siebtrommel abgelegt werden, wobei das Vlies anschließend durch Wärmeeinwirkung eine Verfestigung erfährt, . The invention relates to a random fleece and a method for Manufacture of such a random web from endless threads or fibers, which vorzugxieise for web formation on a sieve, preferably a sieve drum, are placed under suction, the fleece then being solidified by the action of heat,.
Es ist bekannt, Wirrvliese aus endlosen Fäden herzustellen. Derartige Vliese werden auch Spinnvliese genannt. Ferner ist es bekannt, einen bestimmten Anteil, z* B-,. Io %, an Bindefasern zur Vliesbildung mit zu verwenden. Als Bindefasern können sowohl eine modifizierte Faser aus Polyamid oder Polyester verwendet werden, als auch eine Polypropylenfaser oder eine andere thermoplastische Faser. Durch Erwärmen des Vlieses auf die Schmelztemperatur der Bindefaser erfolgt ein Verschweißen des Vlieses durch Anschmelzen der Bindefaser. Bei Polypropylen als Bindefaser ist es auch bekannt, durch. Druck eine Kaltverschweißung vorzunehmen. Eine derartige KaItverschweißung ist jedoch nur bei sehr dünnen Vliesen, bei denen Polypropylen den überwiegenden Faseranteil bildet. Eine gleichmäßige Bindung bzw. Verfestigung erhält man nur dann, wenn die Bindefaser auch gleichmäßig im Vlies verteilt ist. Eine derartige gleichmäßige Verteilung ist jedoch außerordentlich schwierig zu erreichen.It is known to produce tangled webs from endless threads. Such nonwovens are also called spunbonded nonwovens. Further it is known to have a certain proportion, z * B- ,. Io%, on To use binding fibers for fleece formation with. A modified polyamide fiber can be used as the binding fiber or polyester can be used, as well as a polypropylene fiber or other thermoplastic fiber. By heating of the fleece to the melting temperature of the binding fiber, the fleece is welded by melting the binding fiber. In the case of polypropylene as a binding fiber, it is also known by. Cold welding under pressure. Such a cold weld However, this is only possible with very thin nonwovens, in which polypropylene forms the predominant fiber content. One uniform bonding or consolidation is only obtained if if the binding fiber is also evenly distributed in the fleece. However, such an even distribution is extremely difficult to achieve.
Der Erfindung liegt die Aufgabe zugrunde, die gleichmäßige Verfestigung derartiger Vlies© zu verbessern,The invention is based on the object of uniform solidification to improve such fleece ©,

Erfindungsgemäß wurde erkannt, daß eine vollständig gleich- ν J .; ..". mäßige Verteilung der Bindefäsern erreicht werden kann,wenn anstelle von zwei verschiedenen Fasern eine unfixierte Bi- ' Komponenten-Faser verwendet wird. Es wird deshalb vorgeschlagen, : als endlose Fäden oder Fasern eine derartige unfixierte Bi-: .". Komponenten-Faser zu verwenden, wobei die eine Faser-Komporiente; bei einer niedrigeren Temperatur als die andere Schrumpfen öder Schmelzen soll, z. B. um ca. 2o - 5o° C niedrigeren Temperatur«;;According to the invention it was recognized that a completely equal ν J. ; .. ". moderate distribution of the binding fibers can be achieved if instead of two different fibers an unfixed bi-component fiber is used. To use component fiber, the one being a fiber component; should shrink or melt at a lower temperature than the other, e.g. B. by approx. 2o - 5o ° C lower temperature «;;
Es ist eine Bi-Komponentcn-Faser bekannt, bei der der eine An-■■.-": teil aus einer Hochschrumpffaser besteht„ Durch Erwärmen dieser . ; Faser wird gleichzeitig ein dreidimensionaler Kräüseleffekt ;; erreicht. Verwendet man eine derartige unfixierte Bi-Komponenten-: Faser zur Bildung eines Wirrvlieses, und erwärmt dieses Vlies, so wird gleichzeitig durch 'die dabei nun einsetzende Kräuselung r ein starker Schrumpf des Vlieses und eine Verfilzung der :. - ;v Einzelfäden erreicht und damit eine entsprechende Verfestigung. Derartige Vliese können anschließend beispielsweise für Synthese-*; leder verwendet werden und für diesen Zweck mit einem, Synthese-ν-latex oder einem anderen Binde- und Füllmittel imprägniert wer-.;' den. Es sind auch Fasern bekannt, bei denen die* eine FaserkompG— nente bei einer niedrigeren Temperatur, z... B-. 2o - 5o° riiedrigeren Temperatur schmilzt alsdie andere Faserkomponente. ^" ;.There is known a bi-Komponentcn fiber in which a check ■■ .- ": part of a high-shrinkable fiber is" By this heating, the fiber is at the same time a three-dimensional Kräüseleffekt; reaches Using such an unfixed Bi-.. Component: fiber for the formation of a random fleece, and if this fleece is heated, the resulting crimping r causes a strong shrinkage of the fleece and a felting of the:. - ; v individual threads and thus a corresponding solidification then, for example, can be used for synthetic leather and impregnated for this purpose with a synthetic ν latex or another binding and filler. Fibers are also known in which one fiber component melts at a lower temperature, e.g. 20 - 50 lower temperature than the other fiber component.

Besonders günstig ist es, wenn das Vlies zur Verfestigung auf ^ einem unter Saugzug stehenden Sieb, z. B. auf einer oder mehreren Siebtrommeln auf Schrumpf- bzw.

Es hat sich gezeigt, daß eine bessere Verfestigung des Vlieses erreicht werden kann, wenn dieses nach der Erwärmung auf Schrumpf- bzw. Schmelztemperatur eine mechanische Verdichtung, z. B. durch Zusammenpressen erfährt. Durch diese mechanische Verdichtung erfolgt eine Relativbewegung der Einzelfasern zueinander und damit ein besseres Verschmelzen, bzw. bei einem Schrumpfprozess wird dadurch die Verfilzung verstärkt.It has been shown that a better consolidation of the fleece can be achieved if this after heating to shrinkage or melting temperature a mechanical compression, z. B. learns by pressing together. This mechanical compression takes place a relative movement of the individual fibers to one another and thus a better fusion, or with a shrinking process this increases the matting.
Die Verdichtung kann beispielsweise durch ein gekühltes Presswalzenpaar erfolgen. Als besonders gpnstig hat sich jedoch herausgestellt, die Verdichtung des Vlieses zwischen zwei Sieben vorzunehmen, wobei das Vlies vorzugsweise während eines Teiles der Verdichtung gekühlt wird. Auch zur Kühlung ist es wiederum zweckmäßig, ein Gas, ζ. 3. Luft oder Dampf, durch das zusammengedrückte Vlies zu leiten. Die Kühlung kann jedoch auch durch eine Flüssigkeit, z« B. Wasser, erfolgen, das auf bzw« durch das Vlies geleitet wird. . The compression can take place, for example, by a cooled pair of press rollers. However, it has been found to be particularly advantageous to compress the fleece between two sieves, the fleece preferably being cooled during part of the compression. Again, it is advisable to use a gas for cooling, ζ. 3. Pass air or steam through the compressed fleece. The cooling can, however, also take place using a liquid, for example water, which is passed onto or through the fleece. .
Ein sehr gleichmäßiges Wirrvlies erhält man, wenn bei der Vliesbildung die Einzelfäden auf einem sich bewegenden, unter Saugzug stehenden Sieb abgelegt werden und während des Ablegeprozesses eine Kreisbewegung ausführen. A very uniform random fleece is obtained when the individual threads are placed on a moving, underneath the fleece during the formation of the fleece Sieve standing by suction and perform a circular movement during the laying process.
