Definitions

  • the invention relates to a method for producing geotextiles with defined adjustable isotropy, in particular the mechanical properties in the longitudinal and transverse directions.
  • AT 399 169 B discloses a method for controlling the anisotropy of the nonwoven properties in the longitudinal and transverse directions, in which the oscillation frequency of the baffle plates when the threads are deposited is varied depending on the desired ratio of the anisotropy.
  • the object of the invention was to provide a process for producing geotextiles with a defined isotropy, in which the desired mechanical properties can be set in any direction in a defined manner.
  • the invention therefore relates to a method for producing geotextiles with a defined isotropy, characterized in that the melt-spun filaments are deposited in at least 2 layers, the filaments being deposited in the first deposit by baffle plates, predominantly in parallel, at an angle adjustable by the baffle plates and a second shelf in the same way, but mirrored.
  • thermoplastically processable plastics can be used to produce the filaments, for example polyolefins, polyester or
  • BESTATIGUNGSKOPIE Polyamides preferably polyolefins, in particular polypropylene and polyester, are used.
  • the filaments are usually produced from the melt of the corresponding polymer, optionally with the addition of processing aids.
  • the filaments or filaments extruded from a spinneret can be cooled and drawn. They are then placed on a conveyor belt using a guide plate.
  • 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.
  • 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.
  • the nonwoven laid down in the manner according to the invention can then be consolidated in the usual way, both known needling methods and water jet consolidation methods being able to be used.
  • a process for solidification is used particularly advantageously in which the filaments are deposited on a screen belt in the manner according to the invention, which then transports the deposited filaments at least into the first consolidation stage
  • the melt-spun filaments are therefore initially deposited on the endless screen belt in the manner according to the invention and transported to the first consolidation stage on this screen belt.
  • the deposited filaments are fixed on the sieve belt during transport by suction zones so that no disturbances can occur during the transport of the unconsolidated filaments.
  • the water jets act through the sieve belt and / or the sieve belt serves as a base.
  • the geotextile After hardening in the first hardening stage, the geotextile is sufficiently hardened so that it can be guided without disturbing the structure without the support of a conveyor belt. If necessary, the sieve belt can also be passed through any further consolidation stages.
  • the geotextiles produced in this way are characterized by great homogeneity and uniformity and their defined mechanical properties in the longitudinal and transverse directions.
  • geotextiles produced according to the invention can therefore be used in particular for fastening, as a substructure or drainage installations in streets, paths, Bridges, airport runways, embankments, dams and the like can be used.
