Abstract

The melt-spun filaments are deposited in two or more layers. Guide sheets control the angle of filament deposition. They are placed essentially parallel in a first layer. A second layer is laid in the same manner, but in mirror-reversal. An Independent claim is included for the geotextile so prepared.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Geotextilien mit definierter einstellbarer Isotropie, insbesondere der mechanischen Eigenschaften in Längs- und Querrichtung.The invention relates to a method for producing geotextiles defined adjustable isotropy, especially the mechanical Longitudinal and transverse properties.

Gemäß der DE 23 0 331 wird ein weitgehendes isotropes Verhalten der Eigenschaftswerte in Längs- und Querrichtung, beispielsweise durch die Verwendung eines schwingenden Prallblechs bei der Ablage der Fäden auf das Transportband erreicht.According to DE 23 0 331 a largely isotropic behavior of the Property values in the longitudinal and transverse directions, for example by the Use a swinging baffle when placing the threads on the Conveyor belt reached.

In der AT 399 169 B ist ein Verfahren zur Steuerung der Anisotropie der Vlieseigenschaften in Längs- und Querrichtung bekannt, bei dem die Schwingungsfrequenz der Prallbleche bei der Ablage der Fäden in Abhängigkeit von gewünschten Verhältnis der Anisotropie variiert wird.AT 399 169 B describes a method for controlling the anisotropy of the Nonwoven properties in the longitudinal and transverse directions are known, in which the Vibration frequency of the baffle plates when the threads are deposited in Depending on the desired ratio of anisotropy is varied.

Aufgabe der Erfindung war es ein verfahren zur Herstellung von Geotextilien mit definierter Isotropie bereitzustellen, bei dem die gewünschten mechanischen Eigenschaften in jeder Richtung definiert einstellbar sind.The object of the invention was to provide a method for producing geotextiles To provide defined isotropy in which the desired mechanical Properties can be defined in any direction.

Gegenstand der Erfindung ist daher ein Verfahren zur Herstellung von Geotextilien mit definierter Isotropie, dadurch gekennzeichnet, dass die schmelzgesponnen Filamente in mindestens 2 Schichten abgelegt werden, wobei die Filamente in der ersten Ablage durch Leitbleche vorwiegend parallel nebeneinander in einem durch die Leitbleche einstellbaren Winkel abgelegt werden und einer zweiten Ablage auf gleiche Weise, jedoch spiegelverkehrt abgelegt werden.The invention therefore relates to a method for producing Geotextiles with defined isotropy, characterized in that the melt-spun filaments are deposited in at least 2 layers, the filaments in the first deposit being predominantly parallel by baffles placed next to each other at an angle adjustable by the guide plates and a second shelf in the same way, but mirrored be filed.

Zur Herstellung der Filamente können alle thermoplastisch verarbeitbaren Kunststoffe verwendet, werden, beispielsweise Polyolefine, Polyester oder Polyamide, bevorzugt werden Polyolefine, insbesondere Polypropylen und Polyester verwendet.All filaments can be processed thermoplastically to produce the filaments Plastics are used, for example polyolefins, polyester or Polyamides, preferably polyolefins, in particular polypropylene and Polyester used.

Die Filamente werden üblicherweise aus der Schmelze des entsprechenden Polymers, gegebenenfalls unter Zusatz von Verarbeitungshilfsmittel erzeugt. Üblicherweise können die aus einer Spinndüse extrudierten Filamente oder Fäden gekühlt und verstreckt werden. Anschließend werden sie mittels eines Leitblechs auf ein Transportband abgelegt.The filaments are usually made from the melt of the corresponding Polymers, optionally with the addition of processing aids. Usually, the filaments or extruded from a spinneret Threads are cooled and stretched. Then you are using a Guide plate placed on a conveyor belt.

Vorzugsweise erfolgt die Ablage der Filamente über ein Leitblech weitgehend parallel zueinander.
Dabei kann der Ablagewinkel durch Verstellen des Leitblechs definiert eingestellt werden, wobei unter dem Ablagewinkel ein Winkel verstanden wird, dessen einer Schenkel das Leitblech und dessen zweiter Schenkel eine gedachte Linie rechtwinklig zur Produktionsrichtung darstellen.
Anschließend wird zumindest eine zweite Lage der Filamente über die so definiert abgelegte Lage der Filamente abgelegt und zwar spiegelverkehrt.The filaments are preferably deposited largely parallel to one another via a guide plate.
The placement angle can be set in a defined manner by adjusting the guide plate, the placement angle being understood to mean an angle, one leg of which represents the guide plate and the second leg of which is an imaginary line perpendicular to the direction of production.
Subsequently, at least a second layer of the filaments is deposited over the layer of the filaments that has been defined in this way, in a mirror-inverted manner.

Durch Variation dieses Winkels kann das Verhältnis der Längsfestigkeit zur Querfestigkeit definiert gewählt werden, wobei je größer dieser Winkel ist, desto größer ist das Verhältnis der Längsfestigkeit zur Querfestigkeit.
Gegebenfalls können auf diese Weise mehrere Lagen, jeweils spiegelverkehrt über der letzten Lage von Filamenten abgelegt werden.The ratio of the longitudinal strength to the transverse strength can be selected in a defined manner by varying this angle, the larger this angle, the greater the ratio of the longitudinal strength to the transverse strength.
If necessary, several layers can be deposited in this way, each mirrored over the last layer of filaments.

Anschließend kann das auf die erfindungsgemäße Weise abgelegte Vlies auf übliche Weise verfestigt werden, wobei sowohl bekannte Nadelungsverfahren als auch Wasserstrahlverfestigungsverfahren eingesetzt werden können.The fleece deposited in the manner according to the invention can then be opened are solidified in the usual way, using both known needling methods as well as hydroentangling processes can be used.

Besonders vorteilhaft wird dabei ein Verfahren zur Verfestigung angewendet werden, bei dem die Filamente auf erfindungsgemäße Weise auf einem Siebband abgelegt werden, das dann die abgelegten Filamente zumindest in die erste Verfestigungsstufe transportiert A method for solidification is used particularly advantageously be, in which the filaments in a manner according to the invention on a Sieve belt are deposited, which then the deposited filaments at least in transported the first consolidation stage

Die schmelzgesponnenen Filamente werden also vorerst auf erfindungsgemäße Weise auf dem endlosen Siebband abgelegt und auf diesem Siebband zur ersten Verfestigungsstufe transportiert. Die abgelegten Filamente werden dabei während des Transports auf dem Siebband durch Saugzonen fixiert, sodass keine Störungen beim Transport der unverfestigten Filamente auftreten können.The melt-spun filaments are therefore initially open deposited and on the endless screen belt according to the invention transported to the first consolidation stage. The filed Filaments are passed through on the sieve belt during transport Suction zones fixed, so that no disturbances during transport of the unconsolidated Filaments can occur.

In der ersten Verfestigungsstufe wirken die Wasserstrahlen je nach Anordnung der Verfestigungseinrichtung durch das Siebband und/oder das Siebband dient als Unterlage.In the first consolidation stage, the water jets act depending on the arrangement serves the solidification device through the sieve belt and / or the sieve belt as a base.

Nach der Verfestigung in der ersten Verfestigungsstufe ist das Geotextil ausreichend verfestigt, sodass es ohne Störungen der Struktur auch ohne Unterstützung eines Transportbandes geführt werden kann.
Gegebenenfalls kann das Siebband aber auch durch etwaige weitere Verfestigungsstufen geführt werden.After hardening in the first hardening stage, the geotextile is sufficiently hardened so that it can be guided without disturbing the structure, even without the support of a conveyor belt.
If necessary, the sieve belt can also be passed through any further consolidation stages.

Auf dem Siebband findet also sowohl die Vliesbildung als auch die Verfestigung statt.Both the fleece formation and the consolidation take place on the sieve belt instead of.

Durch dieses Verfahren ist es mögliche jede Störung in der Struktur des noch unverfestigten Geotextils nach der Ablage zu vermeiden.
Es können daher aufwendige Verfahrensführungen wie beispielsweise eine wechselseitige Führung vermieden werden.With this method it is possible to avoid any disturbance in the structure of the still unconsolidated geotextile after it has been deposited.
Complex procedures, such as mutual guidance, can therefore be avoided.

Die auf diese Weise hergestellten Geotextilien zeichnen sich durch große Homogenität und Gleichmäßigkeit und seine definierten mechanischen Eigenschaften in Längs- und Querrichtung aus.The geotextiles produced in this way are characterized by large Homogeneity and uniformity and its defined mechanical Properties in the longitudinal and transverse directions.

Die erfindungsgemäß hergestellten Geotextilien können daher insbesondere zur Befestigung, als Unterbau oder Drainageeinbauten in Straßen, Wegen, Brücken, Flughafenpisten, Böschungen, Dämmen und dergleichen verwendet werden. The geotextiles produced according to the invention can therefore in particular for fastening, as a substructure or drainage installation in streets, paths, Bridges, airport runways, embankments, dams and the like are used become.
