Abstract
Description
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Herstellung strukturierter Vliesstoffe gemäß dem Oberbegriff des Verfahrens- bzw. des Vorrichtungsanspruches.The The invention relates to a method and a device for the production structured nonwovens according to the preamble the method or device claim.
Aus
der
Fasern und/oder Filamente aufweisende Vliesstoffe werden zur Verbesserung der Optik, der Haptik bzw. des Gebrauchszweckes mit einer Strukturierung versehen. Bekannt ist eine Strukturierung, welche aus einer Schar parallel zueinander verlaufender Linien besteht, wobei diese Linienschar insgesamt einen Streifen ergibt. Parallel zu diesem Streifen verläuft ein weiterer Streifen mit Linien, wobei die Linien in diesem Streifen in einem Winkel zu den Linien des benachbarten Streifens verlaufen. Meist weist eine Vliesstoffbahn eine Vielzahl solcher Streifen mit in einem Winkel zueinander verlaufenden Linien auf. Ein derartiges Muster wird zumeist als Fischgrätenmuster, Grätenstich oder Hexenstich (engl. Herringbone) bezeichnet.fibers and / or filaments non-woven fabrics are used to improve the look, the feel or the purpose of use with a structuring Mistake. Known is a structuring, which from a crowd consists of mutually parallel lines, this line of people Total results in a strip. Parallel to this strip runs another strip with lines, with the lines in this strip at an angle to the lines of the adjacent strip. In most cases, a nonwoven web has a plurality of such strips at an angle to each other extending lines. Such a thing Pattern is mostly used as herringbone pattern, fishbone engraving or witch engraving (English herringbone).
Derartig strukturierte Vliese werden mittels einer Wasserstrahlvernadelung auf einem diese Struktur ergebenden Sieb hergestellt. Das Sieb ist entsprechend gewebt und prägt während der Wasserstrahlvernadelung das Vlies.Such structured fleeces are made by means of a water jet needling made on a sieve resulting in this structure. The sieve is appropriate woven and embossed during water jet needling the fleece.
Bekannt
ist ferner die Strukturierung von Vliesstoffen mittels Strukturtrommeln
und einer Beaufschlagung mit Druckwasserstrahlen. Die hierbei zu
verwendenden Strukturtrommeln bestehen aus einer Trommelschale mit
der auf das Vlies zu übertragenden Oberflächenstruktur.
Die Trommelschale (Strukturschale) wird auf eine Siebtrommel mit
einer Absaugeinrichtung aufgezogen. Die Trommelschale weist über
ihren Außenumfang verteilt eine Vielzahl von Entwässerungsöffnungen
auf, wobei die Entwässerungsöffnungen meist in
Form eines regelmäßigen Gitters über
die Fläche verteilt sind. Ein Beispiel für eine
Strukturtrommel aus Metall zeigt die
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 die Herstellbarkeit sowie die optischen und/oder haptischen Eigenschaften des entsprechend erzeugten Stoffes 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 with regard to manufacturability as well as the optical and / or haptic Properties of the correspondingly produced substance.
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 das zu strukturierende Vlies während der Beaufschlagung mit einem unter Druck stehenden Medium um den Umfang einer Trommel geführt wird, wobei die Trommeloberfläche bzw. die Oberfläche einer auf der Trommel sitzenden Trommelschale eine ein Fischgrätenmuster ergebende Oberflächenstrukturierung aufweist. Die Trommel weist dazu eine Schar von kreuz und quer zueinander angeordneten, in Streifen um den Umfang der Trommel umlaufender, dreidimensional im Material der Trommel bzw. der Trommelschale geformter Rillen (Rippen) auf, welche das Vlies nach Art eines Fischgrätenmusters zeichnen. Zum Abfördern des Wassers, mit dem die Beaufschlagung des Vlieses erfolgt, sind über die Oberfläche der Trommel bzw. der Trommelschale Entwässerungsöffnungen verteilt angeordnet. Die Entwässerungsöffnungen sind bevorzugt in Form eines gleichmäßigen Gitters, in sonstig geometrisch geordneter Struktur oder zufällig über die Oberfläche der Trommeloberfläche verteilt.According to the Invention is provided that the nonwoven to be structured during the application of a pressurized medium to the Scope of a drum is guided, the drum surface or the surface of a drum shell seated on the drum a herringbone surface texture having. The drum has a crowd of criss-crosses to each other arranged, in strips around the circumference of the drum rotating, three-dimensional in the material of the drum or drum shell shaped grooves (Ribs) on which the fleece in the manner of a herringbone pattern to draw. For removing the water, with the admission fleece is over the surface the drum or drum shell drainage holes arranged distributed. The drainage holes are preferably in the form of a uniform grid, in otherwise geometrically ordered structure or randomly over distributed the surface of the drum surface.
Eine derartige Trommelschale kann bevorzugt als eine Metallhülse gestaltet sein, in dessen Außenoberfläche die das Fischgrätenmuster ergebenden Rillen nebst den dazwischen liegenden Einsenkungen dreidimensional eingeformt sind. Vorzugsweise erfolgt dies mittels eines elektro-chemischen Bearbeitungsverfahren. Gemäß einer weiteren bevorzugten Ausführung kann die Trommelschale eine Hülse aus einem Kunststoffmaterial sein, dessen Außenoberfläche mittels eines Laserverfahrens entsprechend dreidimensional gestaltet wurde.A Such drum shell may be preferred as a metal shell be designed in the outer surface of the the herringbone grooves along with the intervening grooves lying depressions are molded three-dimensionally. Preferably this is done by means of an electro-chemical processing method. According to another preferred embodiment The drum shell may be a sleeve of a plastic material be whose outer surface by means of a laser process was designed accordingly three-dimensional.
Die Höhendifferenz zwischen den Rippen und den Einsenkungen der dreidimensionalen Strukturierung beträgt bevorzugt 0.1–2 mm. Die Entwässerungsöffnungen liegen bevorzugt im Durchmesserbereich von 0.2–0.8 mm.The Height difference between the ribs and the depressions the three-dimensional structuring is preferred 0.1-2 mm. The drainage holes are preferably in the diameter range of 0.2-0.8 mm.
Eine weitere Gestaltung der Erfindung sieht vor, dass die zwischen den Rippen liegenden Einsenkungen als entsprechende Ausschnitte, Öffnungen der Trommelschale gestaltet sind. Bei dieser Ausführung der Erfindung formen die Öffnungen das Vlies – durch diese Öffnungen erfolgt ferner der Flüssigkeitstransport.A further embodiment of the invention provides that the depressions lying between the ribs are designed as corresponding cutouts, openings of the drum shell. In this embodiment of the invention, the openings form the fleece - through these openings also takes place the liquid transport.
Bevorzugt erfolgt die erfindungsgemäße Vliesherstellung mit unter Druck stehendem Wasser. Bei Herstellung eines Vlieses, welches thermoplastische Fasern und/oder Filamente aufweist bzw. dessen Fasern und/oder Filamente thermoplastische Anteile besitzen, kann eine Strukturierung auch mittels unter Druck stehendem heißen (vorzugsweise überhitztem) Dampf durchgeführt werden.Prefers the nonwoven production according to the invention takes place with pressurized water. When producing a fleece, which comprises thermoplastic fibers and / or filaments or whose fibers and / or filaments have thermoplastic components, can also be called structuring by means of pressurized (preferably superheated) steam performed become.
Des weiteren erfolgt die Erläuterung eines Ausführungsbeispieles der Erfindung anhand der Zeichnungen.Of Further, the explanation of an embodiment takes place the invention with reference to the drawings.
