Abstract
Ein Vlies mit unterschiedlicher Orientierung der Fasern in Schichten wird durch eine Vliesbildung und einen Kämmvorgang erzeugt.A fleece with different orientations of the fibers in layers is produced by fleece formation and a combing process.
Description
Es ist bekannt, Vliese mit einer Wirrlage oder mit einer orientierten Faserlage herzustellen. Bei orientierten Vliesen werden die Fasern von der Krempel hauptsächlich in Maschinenrichtung, hierunter versteht man die Laufrichtung der Faserbahn als Vlies, gelegt.It is known to produce nonwovens with a random layer or with an oriented fiber layer. In the case of oriented nonwovens, the fibers from the card are mainly laid in the machine direction, which means the running direction of the fiber web as the nonwoven.
Was der Fachmann unter Faserorientierung (-ausrichtung) versteht, ist bei Kathrin Pietsch/ Hilmar Fuchs in „Textile Werkstoffe für den Leichtbau“, Kapitel 9.3.2.2 „Vliesstoffhalbzeuge und Vliesbildungstechniken“ beschrieben.What the expert understands by fiber orientation (alignment) is described by Kathrin Pietsch / Hilmar Fuchs in "Textile materials for lightweight construction", Chapter 9.3.2.2 "Nonwoven semi-finished products and nonwoven forming techniques".
Ein solches Vlies kann durch einen sogenannten Kreuzleger oder Täfler in versetzten übereinanderliegenden Lagen auf ein bewegtes Band kontinuierlich abgeliefert werden. Die Fasern in den Lagen haben dann eine hauptsächliche Ausrichtung quer zur Laufrichtung des Abzugbandes. Durch Einstellen der Abliefergeschwindigkeit des Legewagens zur Geschwindigkeit des Abzugbandes sind bis 45° Ausrichtungen möglich. Durch Verziehen dieses Mehrlagenvlieses kann die Faserausrichtung des Vlieses weiter in Richtung der Laufrichtung des Abzugsbandes ausgerichtet werden. Bei allen diesen Verfahren ist die Ausrichtung im Vlies gleichgerichtet. Man kann Vliese mit unterschiedlicher Ausrichtung durch Zusammenführen von separat auf unterschiedlichen Maschinen gefertigten Vlieslagen produzieren.Such a fleece can be continuously delivered to a moving belt by a so-called cross-layer or panel in staggered superimposed layers. The fibers in the layers then have a main orientation transverse to the running direction of the take-off belt. By adjusting the delivery speed of the laying trolley to the speed of the discharge belt, alignments of up to 45 ° are possible. By distorting this multilayer fleece, the fiber orientation of the fleece can be further aligned in the direction of the running direction of the take-off belt. In all of these processes, the alignment in the fleece is the same. You can produce nonwovens with different orientations by bringing together layers of nonwoven produced separately on different machines.
Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, bei dem aus einem Vlies ein Vlies mit mindestens
Fasern
Die Fasern sind durch den Ablageprozess quer zur Laufrichtung des Bandes abgelegt und eine Faserschicht
Es ist auch denkbar, den Kämmprozess auf der unteren Seite des Vlieses zu wiederholen. Auf diese Weise kann ein Vlies mit hervorragender Längs- zu Quer-Festigkeit erzeugt werden. In einigen Anwendungen ist diese webartige Struktur erwünscht.It is also conceivable to repeat the combing process on the lower side of the fleece. In this way, a fleece with excellent longitudinal to transverse strength can be produced. In some applications this web-like structure is desirable.
