Description

Die Erfindung betrifft eine Spinnplatte zur Herstellung von schmelzgesponnen Fasern zur Herstellung von Geotextilien.The invention relates to a spinning plate for the production of melt-spun Fibers for the production of geotextiles.

Geotextilien werden in vielen Bereichen der Technik angewendet, im besonderen für die Befestigung von Böschungen, Abhängen, als Unterlage für Beton- oder Asphaltflächen wie Straßen, Flughäfen, Wege, Brücken und dergleichen, und zwar sowohl für Neubauten als auch für Sanierungen verwendet. Entsprechend dem spezifischen Anwendungsgebiet werden besondere Anforderungen an die Stabilität, die Festigkeit, die Wasserdurchlässigkeit der Geotextilien gestellt.Geotextiles are used in many areas of technology, in especially for fixing embankments, slopes, as a base for Concrete or asphalt surfaces such as roads, airports, paths, bridges and the like, both for new buildings and for renovations used. According to the specific area of application special requirements for stability, strength, the Permeability of geotextiles provided.

Bei der Herstellung von Geotextilien werden bisher je nach der geforderten Eigenschaft Fasern und Filamente verschiedener definierter Texturen hergestellt und verfestigt. Je feiner die Fasern oder Filamente, desto fester, stabiler ist das Geotextil nach der Verfestigung, je gröber die Fasern oder Filamente, desto höher ist die Wasserdurchlässigkeit des Geotextils Gegebenenfalls werden vor der Verfestigung eines Geotextils getrennt hergestellte feiner Fasern zugemischt um eine entsprechende Festigkeit und Stabilität zu erreichen.So far, the manufacture of geotextiles depends on the required Property fibers and filaments of different defined textures manufactured and solidified. The finer the fibers or filaments, the firmer The geotextile is more stable after consolidation, the coarser the fibers or Filaments, the higher the water permeability of the geotextile If necessary, they are separated before a geotextile is consolidated produced fine fibers mixed to a corresponding strength and To achieve stability.

Aufgabe der Erfindung war es ein Verfahren und eine Vorrichtung zur Herstellung von Geotextilien bestehend aus Fasern oder Filamenten unterschiedlicher Textur bereitzustellen, bei dem die Mischung bzw. die Einstellung der Fasermischung nicht aufwendig nach der Herstellung der Fasern und Filamente erfolgt sondern bereits bei der Herstellung der Fasern bzw. Filamente erfolgt.The object of the invention was a method and an apparatus for Manufacture of geotextiles consisting of fibers or filaments to provide different texture, in which the mixture or Adjustment of the fiber mixture is not expensive after the production of the Fibers and filaments take place during the manufacture of the fibers or filaments.

Gegenstand der Erfindung ist daher ein Verfahren zur Herstellung von Geotextilien, dadurch gekennzeichnet, dass die Herstellung der Endlosfasern unterschiedlicher Textur in einem Spinnvorgang erfolgt, wodurch das Verhältnis von Fasern feinerer und gröberer Textur definiert eingestellt wird und bei der anschließenden mechanischen und/oder hydraulischen Verfestigung ein Geotextil definierter Eigenschaften hergestellt wird.The invention therefore relates to a method for producing Geotextiles, characterized in that the manufacture of continuous fibers Different texture takes place in one spinning process, which reduces the ratio is defined by fibers of finer and coarser texture and at subsequent mechanical and / or hydraulic consolidation Geotextile defined properties is produced.

Ein weiterer Gegenstand der Erfindung ist eine Spinnplatte zur Herstellung von schmelzgesponnenen Endlosfasern für Geotextilien, dadurch gekennzeichnet, dass die Spinnplatte Bohrungen unterschiedlichen Durchmessers zur Herstellung von Fasern unterschiedlicher Textur in einem Spinnvorgang aufweist.Another object of the invention is a spinning plate for the production of melt-spun continuous fibers for geotextiles, characterized in that that the spinning plate holes for different diameters Production of fibers of different textures in one spinning process having.

Durch den Anteil der feineren Fasern kann die gewünschte Stabilität und Festigkeit des fertigen Geotextils eingestellt werden. Der Anteil an gröberen Fasern bestimmt die hydraulischen Eigenschaften des fertigen Geotextils, beispielsweise die Wasserdurchlässigkeit in der Vliesebene bzw. vertikal zur Vliesebene.
Je höher der Anteil an feinen Fasern ist, desto fester und stabiler wird das anschließend durch mechanische und/oder hydraulische Verfestigung hergestellte Geotextil. Je höher der Anteil an gröberen Fasern ist, desto größer die wird die Wasserdurchlässigkeit des Geotextils nach der mechanischen und/oder hydraulischen Verfestigung.The desired stability and strength of the finished geotextile can be set by the proportion of the finer fibers. The proportion of coarser fibers determines the hydraulic properties of the finished geotextile, for example the water permeability in the fleece plane or vertically to the fleece plane.
The higher the proportion of fine fibers, the stronger and more stable the geotextile subsequently produced by mechanical and / or hydraulic consolidation. The higher the proportion of coarser fibers, the greater the water permeability of the geotextile after mechanical and / or hydraulic consolidation.

Als Rohstoffe sowohl für die feinen als auch für die gröberen Fasern kommen beispielsweise Kunststoffe wie Polypropylen, Polyethylen, Polyamid oder Polyester in Frage.Coming as raw materials for both fine and coarser fibers for example plastics such as polypropylene, polyethylene, polyamide or Polyester in question.

Unter feinen Fasern, die zur mechanischen und oder hydraulischen Verfestigung des Geotextils dienen, werden Fasern einer Textur von 1- 10 dtex, vorzugsweise 1 - 7 dtex, verstanden. Die gröberen Fasern weisen in Abhängigkeit von der gewählten Textur der feineren Fasern eine Textur von 6 - 30 dtex, vorzugsweise 7 - 27 dtex, auf. Among fine fibers used for mechanical and or hydraulic Serve to solidify the geotextile, fibers with a texture of 1-10 dtex, preferably 1-7 dtex, understood. The coarser fibers show in Depending on the selected texture of the finer fibers, a texture of 6 - 30 dtex, preferably 7-27 dtex.

Vorzugsweise unterscheiden sich die Texturen der Fasertypen um einen Faktor 3 bis 20, besonders bevorzugt 4 - 6.The textures of the fiber types preferably differ by a factor 3 to 20, particularly preferably 4-6.

Der Anteil an feinen Fasern im fertigen Geotextil kann je nach den gewünschten Eigenschaften, als insbesondere der gewünschten Kombination aus Festigkeit, Stabilität und Wasserdurchlässigkeit und in Abhängigkeit der gewählten Texturen 20 - 95%, vorzugsweise 30 - 90% betragen.The proportion of fine fibers in the finished geotextile can vary depending on the desired Properties, in particular the desired combination of strength, Stability and water permeability and depending on the chosen Textures are 20-95%, preferably 30-90%.

Es ist aber auch möglich mehr als 2 Fasern unterschiedlicher Textur zu verwenden. In diesem Fall werden dann drei oder mehrer Fasern unterschiedlicher Textur zur Herstellung des Geotextils verwendet, wobei die Auswahl der Texturen wiederum von den gewünschten Eigenschaften des fertigen Geotextils abhängig ist.But it is also possible to have more than 2 fibers of different texture use. In this case there will be three or more fibers different texture used to manufacture the geotextile, the Selection of the textures in turn from the desired properties of the finished geotextile is dependent.

Die Fasern unterschiedlicher Textur werden in einem Spinnvorgang unter Verwendung der erfindungsgemäßen Spinplatte hergestellt. Anschließend werden die Fasern auf übliche Weise abgelegt und mechanisch und/oder hydraulisch, chemisch und/oder thermisch verfestigt.The fibers of different texture are spun in one Manufactured using the spin plate according to the invention. Subsequently the fibers are deposited in the usual way and mechanically and / or hydraulically, chemically and / or thermally solidified.

Zur Herstellung einer definierten Mischung von Fasern oder Filamenten unterschiedlicher Textur wird eine Spinnplatte mit unterschiedlichen definierten Bohrungen verwendet und dadurch das Mischungsverhältnis der Fasern und deren Textur bereits bei der Herstellung der Fasern definiert.For the production of a defined mixture of fibers or filaments Different texture is a spinning plate with different defined Holes and thereby the mixing ratio of the fibers and whose texture is already defined during the production of the fibers.

Diese erfindungsgemäße Spinnplatte weist Bohrungen mit unterschiedlichen Kapillardurchmessern zur gleichzeitigen Herstellung von Endlosfasern unterschiedlicher Textur auf.
Dabei werden die Kapillardurchmesser der Bohrungen so bemessen, dass gleichzeitig die Fasern unterschiedlicher Textur im gewünschten Verhältnis hergestellt werden können.
Die Bohrungen können dabei in regelmäßigen Abständen als auch willkürlich verteilt in der Spinnplatte angeordnet werden. This spinning plate according to the invention has bores with different capillary diameters for the simultaneous production of continuous fibers of different textures.
The capillary diameters of the bores are dimensioned in such a way that fibers of different textures can be produced in the desired ratio at the same time.
The holes can be arranged in the spinning plate at regular intervals as well as arbitrarily distributed.

Die Kapillarbohrungen können je nach gewünschtem Faserquerschnitt geeignete Formen aufweisen (trilobal, oktalobal, sternförmig, hohl, dreieckig, dreieckig hohl, usw. ), wobei auch die Querschnitte für die feinen und die gröberen Fasern, bzw. gegebenenfalls weiterer verwendeter Fasern unterschiedlich sein können. The capillary holes can vary depending on the desired fiber cross section have suitable shapes (trilobal, octalobal, star-shaped, hollow, triangular, triangular hollow, etc.), the cross sections for the fine and the coarser fibers, or possibly other fibers used can be different.
