Abstract
Description
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Vorverfestigung eines Vlieses gemäß dem Oberbegriff des Verfahrens- bzw. des Vorrichtungsanspruches.The The invention relates to a method and a device for preconsolidation of a non-woven according to the preamble of the method or the device claim.
Ein
mittels einer Krempel bzw. einer Spinvliesanlage hergestellter Flor
muss je nach der Art der Weiterverarbeitung vorverfestigt werden.
Dies ist insbesondere dann der Fall, wenn der Flor mittels in einem
Foulard mit einem Schaum behandelt werden soll. Bekannte Methoden
der Vorverfestigung eines Flores basieren auf der Wasserstrahlvernadelung, bei
der der auf einem Transportband liegende Flor von einem weiteren
Endlosband (Kompaktierband) komprimiert und durch ein oder mehrere
Wasserstrahlvernadelungseinrichtungen (Wasserbalken –
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren sowie eine Vorrichtung zur Durchführung des Verfahrens gemäß dem Oberbegriff des Verfahrens- bzw. Vorrichtungsanspruches insbesondere mit Blick auf den Bauteilaufwand zu verbessern.task The present invention is a method and an apparatus to carry out the method according to the General term of the method or device claim in particular to improve with regard to the component cost.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Verfahrens- bzw. Vorrichtungsanspruches. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den jeweiligen Unteransprüchen.Solved this function is achieved by the distinguishing features of the procedure or device claim. Advantageous developments of the invention emerge from the respective subclaims.
Gemäß der Erfindung ist vorgesehen, dass die Einrichtung zur Wasserstrahlvernadelung in einem großen Abstand zu der den Flor tragenden Unterlage positioniert ist. Vorzugsweise beträgt der Abstand zwischen 30 und 100 mm – besonders bevorzugt wird ein Wert zwischen 50 und 80 mm gewählt. Als Abstand gemäß der vorliegenden Erfindung sei hierbei die freie Wegstrecke eines Wasserstrahles zwischen dem Austritt des Wasserbalkens und der das Flor tragenden Unterlage verstanden.According to the Invention is provided that the device for water jet needling at a great distance to the pad supporting the pile is positioned. Preferably, the distance between 30 and 100 mm - particularly preferred is a value between 50 and 80 mm chosen. As a distance according to the present invention here is the free path of a water jet between the exit of the water bar and the pad supporting the pile Understood.
Nach der Erfindung ist dabei ein derartiger Abstand von Wasserbalken zu der den Flor tragenden Unterlage wesentlich, so dass durch die an der Unterseite des Wasserbalkens austretenden Wasserstrahlen in Verbindung mit der unterhalb der Unterlage befindlichen Absaugung eine derartige Schleppströmung ergibt, welche im wesentlichen senkrecht in und durch den Flor dringt.To The invention is such a distance of water bars to the pad supporting the pile substantially, so that through the at the bottom of the water bar exiting water jets in connection with the suction located below the base such a drag flow results, which is substantially perpendicular penetrates into and through the pile.
Bevorzugt ist vorgesehen, dass ein Flor mit einem Flächengewicht kleiner 100 g/m2 verarbeitet wird. Dabei wird gemäß einer bevorzugten Ausführung der Erfindung eine Verarbeitungsgeschwindigkeit von mehr als 100 m/min gefahren.It is preferably provided that a pile with a weight per unit area of less than 100 g / m 2 is processed. In this case, according to a preferred embodiment of the invention, a processing speed of more than 100 m / min driven.
Von Vorteil ist, dass der Wasserdruck der Wasserstrahlvernadelung weniger als 100 bar beträgt. Die Höhe des Wasserdruckes richtet sich hierbei bevorzugt nach der Faser- bzw. Filamentstärke, dem Titer. So sind wird ein Wasserdruck von 20–40 bar bei 1.7 dtex eingestellt. Bei Fasern/Filamenten mit 6 dtex beträgt der einzustellende Wasserdruck bevorzugt 40–80 bar. Der jeweils untere Druckwert ist bei Flächengewichten bis etwa 30 g/m2 zu verwenden, der obere Druckwert gilt für Faser- bzw. Filamentflore, bei denen das Flächengewicht bis 100 g/m2 geht.It is advantageous that the water pressure of the water jet needling is less than 100 bar. The height of the water pressure depends here preferably on the fiber or filament thickness, the titer. Thus, a water pressure of 20-40 bar is set at 1.7 dtex. For 6 dtex fibers / filaments, the water pressure to be set is preferably 40-80 bar. The respective lower pressure value is to be used for basis weights of up to about 30 g / m 2 , the upper pressure value applies to fiber or filament webs where the basis weight is up to 100 g / m 2 .
Des weiteren erfolgt die Erläuterung eines Ausführungsbeispieles anhand der Zeichnungen.Of Further, the explanation of an embodiment takes place based on the drawings.
