Diese Polymerkombinationen sind in Form splittbarer Hohlfasern gesponnen, und zwar in der Segmented-Pie-Anordnung. Die Hohlfaser besteht dabei aus 16 Segmenten.These polymer combinations are spun in the form of splittable hollow fibers, in the segmented pie arrangement. The hollow fiber consists of 16 segments.

Der Titer der gesponnenen, ungesplitteten Hohlfilamente variiert je nach Polymerkombination zwischen 1–2,5 den. Der Hohlraumdurchmesser beträgt 10–20% des Hohlfilamentes. Bevorzugt lassen sich so Vliesstoffe mit einem Flächengewicht von 10–60 g/m2 herstellen.The titer of the spun, unsplit hollow filaments varies depending on the polymer combination between 1-2.5 den. The cavity diameter is 10-20% of the hollow filament. Nonwoven fabrics with a basis weight of 10-60 g / m 2 can preferably be produced in this way.

This consolidation takes place with the following values:
In a subsequent second water jet needling the spunbonded fabric is perforated. Advantageously, the product according to the invention with perforations in the diameter range 1-3 mm. Preference is given to hole diameters of 1.5 mm. The grid spacing is 4 mm so that enough nonwoven material remains between the holes for strength. The rows of holes run in the machine direction and perpendicular thereto (transverse direction). The strength in and across the machine direction is therefore of similar magnitude.

Des Weiteren erfolgt die Erläuterung eines Ausführungsbeispieles anhand der Zeichnungen.Furthermore, the explanation of an embodiment with reference to the drawings.

Gemäß 1 wird ein Flor F mit einem Flächengewicht von ca. 20 g/m2 aus splittbaren Hohlfilamenten mit einem Filament-Titer von 2,2 den einer ersten Vernadelungstrommel V1 zugeführt. Die Hohlfilamente bestehen aus einer zuvorstehend angegebenen Polymerkombination und sind vom Segmented-Pie-Typ – 16 Segmente. Der Flor F aus den Hohlfilamenten kann in einer vorhergehenden Prozessstufe leicht verfestigt sein, insbesondere durch leichtes Kalandrieren, so dass dieser transportiert und an die Vernadelungstrommel V1 übergeben werden kann. Die Vernadelungstrommel V1 weist eine Absaugung A1 auf und ist mit einer Siebtrommelschale S1 überzogen. Im bevorzugten Ausführungsbeispiel handelt es sich um eine Siebtrommelschale S1 mit 40/39 Schuss-/Kettdrähten pro cm. Der Drahtdurchmesser beträgt 0.11 mm.According to 1 a pile F with a basis weight of about 20 g / m 2 of splittable hollow filaments with a filament titer of 2.2 is fed to a first needling drum V1. The hollow filaments consist of a polymer combination given above and are of the segmented pie type - 16 segments. The pile F from the hollow filaments can be easily solidified in a preceding process stage, in particular by light calendering, so that it is transported and transferred to the needling drum V1 can. The needling drum V1 has a suction A1 and is covered with a perforated drum shell S1. In the preferred embodiment, it is a screen drum shell S1 with 40/39 weft / warp wires per cm. The wire diameter is 0.11 mm.

Der Vernadelungstrommel V1 ist ein Düsenbalken D1 zugeordnet, in welchem ein Düsenstreifen mit 40 hpi (Holes per inch) und einem Lochdurchmesser von 0.12 mm montiert ist. Die erste Wasserstrahlbeaufschlagung erfolgt mit einem Druck von 200 bar. Der zugeführte Flor F aus den splittbaren Hohlfilamenten wird verfestigt, indem die Hohlfilamente gesplittet und verschlungen werden.The needling drum V1 is associated with a nozzle beam D1, in which a nozzle strip with 40 hpi (holes per inch) and a hole diameter of 0.12 mm is mounted. The first water jet is applied at a pressure of 200 bar. The supplied pile F from the split hollow filaments is solidified by the hollow filaments are split and entangled.

Das in der ersten hydraulischen Vernadelung verfestigte Spinnvlies wird nun an eine zweite Vernadelungstrommel V2 übergeben, welche zwei Düsenbalken D21, D22 nebst Absaugungen A21, A22 aufweist. In diesen Düsenbalken D21, D22 ist je ein Düsenstreifen mit 60 hpi und 0,12 mm Lochdurchmesser montiert. Die Wasserstrahlbeaufschlagung erfolgt mit einem Druck von 190–240 bar. Auf die zweite Vernadelungstrommel V2 ist eine Siebtrommelschale S2 aufgezogen mit 16/15 Schuss-/Kettdrähten pro cm. Der Drahtdurchmesser beträgt 0,26 mm. Diese Siebtrommelschale S2 enthält ferner aus Kunststoff bestehende Perforationselemente, welche als konvexe Gebilde nach Art von das Siebgewebe benetzenden Wassertropfen ausgeführt sind. Das so hergestellte Spinnvlies wird im Anschluss getrocknet. Das Ergebnis ist ein perforiertes Spinnvlies mit hohen Festigkeitswerten in Maschinen- und Querrichtung. Bei einem Flächengewicht von 20 g/m2 und einem Lochabstand von 4 mm sowie 1,5 mm ergibt sich ein Spinnvliesprodukt, welches für Hygieneartikel oder als Decklage für Windeln verwendbar ist.The spunbonded fabric solidified in the first hydraulic needling is then transferred to a second needling drum V2, which has two nozzle bars D21, D22 together with aspirations A21, A22. A nozzle strip with 60 hpi and 0.12 mm hole diameter is mounted in each of these nozzle bars D21, D22. The water jet is applied at a pressure of 190-240 bar. On the second needling drum V2 a screen drum shell S2 is mounted with 16/15 weft / warp wires per cm. The wire diameter is 0.26 mm. This screen drum shell S2 further contains plastic perforation elements, which are designed as convex structures in the manner of the screen cloth wetting water drops. The spunbonded fabric produced in this way is subsequently dried. The result is a perforated spunbonded fabric with high strength values in the machine and transverse directions. With a basis weight of 20 g / m 2 and a hole spacing of 4 mm and 1.5 mm results in a spunbonded product, which is useful for sanitary articles or as a cover layer for diapers.
