Furthermore, the invention also relates to a device for producing such spunbonded nonwovens. Filaments means in the context of the invention, in particular endless filaments. Endless filaments differ because of their quasi-endless length of staple fibers, which have much smaller lengths of, for example, 10 to 60 mm.
  • the filaments are spun using a spinning device and placed on a tray, in particular on a storage conveyor belt or Ablagesiebband to nonwoven web. It is known to pre-consolidate this nonwoven web by hydroentanglement.
  • the water jet treatment is usually carried out only from one side of the nonwoven web. Thereafter, the preconsolidated filament deposit or nonwoven web is detached from the deposit screen belt and fed to a separate water jet device for hydroentanglement or for hydraulic final consolidation.
  • the energy input of the successively staggered water jet nozzles and the first increases to the other nozzles.
  • the nozzles with the highest energy input are as arranged with respect to the conveying direction of the nonwoven web at the end or in the middle of the water jet device. For nonwoven webs with a very high basis weight, the energy input is so high that the process is no longer practicable.
