Definitions

  • the invention relates to structured geotextiles and methods for their Manufactured by hydrodynamic consolidation processes.
  • Structured geotextiles are used in a variety of applications used. For example, structured geotextiles become targeted and directed drainage of water, especially surface water, for example in embankments, dikes, slopes, in road construction and the like used.
  • the object of the invention was to provide structured geotextiles, which have improved properties, particularly with regard to Water permeability in defined areas both on the geotextile level, as well as vertical to the surface of the geotextile. It was also the task of Invention defines a method and an apparatus for manufacturing such to provide structured geotextiles.
  • the invention therefore relates to structured geotextiles, thereby characterized that the defined structuring through targeted hydrodynamic consolidation process is produced.
  • Another object of the invention is a method for manufacturing structured geotextiles, characterized in that in one hydrodynamic solidification processes defined capillaries the same Diameter, however, with different distances for the production of differently consolidated geotextiles are used in some areas.
  • Methods for the hydrodynamic consolidation of nonwovens are, for example from EP-A 0 896 080, EP-A 101 064, EP-A 0 900 295, EP-A 0967 315, EP-A 0859 076, EP-A 0 841 424, EP 0 727 517 and EP-A 0 751 249 known.
  • nonwovens can be protected Way by flowing out of a nozzle bar
  • Water curtain can be solidified from water jets.
  • the intensity the solidification is essentially the distance from the nozzle bar, or whose holes depending on the water jet emerging. The bigger the Distance of the water jets, the less the matting and the higher the Water permeability of the fleece.
  • Structured geotextiles can be produced by a defined arrangement of the spacing of the water jet nozzles. For example, regular sequences of water jet nozzles with a large distance and water jet nozzles with a small distance can be used to produce regularly structured geotextiles. In the area in which the geotextile is solidified by water jets at a large distance, the solidification is less, the geotextile remains more voluminous and loose. In those areas in which the geotextile is consolidated by water jets with a short distance, the geotextile is strongly consolidated, it becomes flat and firm.
  • the distance of the water jet nozzles can be used for strong flat consolidation be between 0.5 - 0.7 mm, for loose voluminous hardening 1.5 - 3.5 mm.
  • the Distances of the capillaries can be chosen, also depending on the requirement Intermediate values are possible.
  • the capillaries can also be arranged in two or more rows
  • the fleece to be consolidated can consist of staple or continuous fibers.
  • the fibers preferably consist of plastics, such as, for example Polypropylene, polyethylene, polyamide, polyester or mixtures the same.
  • nonwovens can also have bicomponent fibers or consist entirely of such fibers.
  • the nonwovens can also contain parts of natural fibers such as cellulose, hemp, sisal, coconut, kenaf and the like.
  • the fibers can each have different textures and / or Have fiber cross sections.
  • two or more unconsolidated or pre-consolidated nonwovens are placed on top of one another and then, as described, consolidated differently by the hydrodynamic consolidation process using different capillary diameters of the water jet nozzles, so that structured composite nonwovens are formed.
  • the individual fleeces can have different compositions.
