Definitions

  • the invention relates to a method for consolidating a nonwoven fabric artificial staple fibers without binding fibers or binding agents or from said artificial fibers together with natural fibers that are at least 10 mm will be produced.
  • Carded fiber nonwovens are made from a wide variety of fibers. All In general, they have the advantage that the short fibers in the finished fleece get mixed up lie and therefore give the fleece better strength in all tensile directions.
  • nonwovens made from continuous fibers, which are produced after the fibers immediately to a spunbonded nonwoven z. B. stored on an endless belt. The im of the fleece supplied loose laid fibers and also one However, spunbonded nonwovens have to be of satisfactory strength in practice be connected to each other. It is known to mechanically vernadein the fleece. Through this basically discontinuous and therefore slow hardening process but the volume is significantly reduced, so that such mechanically consolidated needle fleece is not suitable for many uses is useful. In addition, thin nonwovens cannot be needled mechanically at all.
  • EP-A-0 418 493 discloses a composite fleece in which a layer is initially used from meltblown fibers onto an endless belt and immediately afterwards carded staple fiber fleece is deposited.
  • the composite is used for solidification and Connection of the fibers of the layers then water needled.
  • the Water needling is used there for the uneven distribution of the fibers to places available with higher and lower fiber density.
  • This solidified fleece shows no binders, but it is ultimately not bulky and does not have that thickness required for the desired purpose.
  • the invention has for its object a method for producing a solidified to develop voluminous fleece, such as carded fiber fleece, for which Solidification no additional binding chemicals or binding fibers are necessary and yet achieved the required strength in the still voluminous fleece can be. and yet achieved the required strength in the still voluminous fleece can be.
  • a means of z. B a card or aerodynamically manufactured Staple fiber fleece deposited on a previously consolidated fleece as a carrier fleece and in one continuous treatment process by means of water needling with a Water pressure of at least 100, preferably 180 bar with the carrier fleece connected and solidified at the same time.
  • the staple fiber fleece - as it does from the Card or delivered by an aerodynamic - with the needling of water with this water pressure loses volume, but only for this purpose insignificant little.
  • the fibers become matted by the impact of the Water jets with the water pressure in such a way that a sufficiently consolidated fleece is supplied by the water needling machine and this at the same time Staple fiber fleece mechanically connected to the carrier fleece, that is to say to the carrier fleece is also needled.
  • Staple fiber fleece mechanically connected to the carrier fleece that is to say to the carrier fleece is also needled.
  • This solidification process is particularly inexpensive because two Actual separate product manufacturing steps combined in one become.
  • the Connection with the spunbond which of course can also be another nonwoven product can.
  • the treatment can also be seen the other way around, namely the connection of the staple fiber fleece with the carrier fleece is carried out at the same time Consolidation of the staple fiber fleece without it being as intended Volume loses.
