Definitions

  • the invention relates to a method for consolidating a nonwoven fabric artificial staple fibers, such as polyester, polyethylene or polypropylene fibers and / or also from such continuous fibers, and / or natural fibers, which have a thickness of 10 mm and more from pure chemical fibers without binding fibers, such as bicomponent or special melt fibers, and is manufactured without binders.
  • a nonwoven fabric artificial staple fibers such as polyester, polyethylene or polypropylene fibers and / or also from such continuous fibers, and / or natural fibers, which have a thickness of 10 mm and more from pure chemical fibers without binding fibers, such as bicomponent or special melt fibers, and is manufactured without binders.
  • Carded fiber nonwovens are made from a wide variety of fibers. All generally they have the advantage that the short fibers in the finished nonwoven mess lie and therefore give the fleece better strength in all tensile directions.
  • nonwovens made from continuous fibers that are produced after the fibers immediately to a fleece z. B. stored on an endless belt.
  • spunbonded nonwovens have to be of satisfactory strength in practice be connected to each other.
  • thin nonwovens cannot be needled mechanically at all.
  • the nonwoven fibers have lower melting synthetic fibers such as also to mix bicomponent fibers, which at least then by the action of heat be melted down so that they bond with the neighboring fibers of the fleece glue.
  • the expensive binding fibers and the additional energy required disadvantageous when heated up to the melting temperature of the binding fibers.
  • EP-A-0 321237 which is a wet-laid nonwoven fabric discloses that is also needled water for solidification. What to achieve Nonwoven should not be voluminous, but should be consolidated flat, and at the same time high Have interlayer adhesive strength. The recital further states that the previously known dry-laid nonwovens are hot pressed for consolidation, what brings sufficient surface consolidation, but not that there desired transverse strength. The document also goes to "spunlaced" nonwovens without adhesives, which are also solidified by water needling. The document states that this type of fleece does not solidify sufficiently and are disadvantageous compared to the wet-strengthened nonwovens.
  • the invention has for its object a method for producing a solidified to develop voluminous fleece, such as carded fiber or staple fiber fleece, in which no additional binding chemicals or binding fibers are used for solidification are necessary and yet the required strength even with this voluminous Fleece is achieved.
  • voluminous fleece such as carded fiber or staple fiber fleece
  • a nonwoven made of fibers having a titer between 1-15 den and weighing up to 200 g / m 2 produced and solidified by means of a single needling of water alone, solidified over the surface with only a water pressure of up to at most 60 bar, preferably 20-30 bar, and then it has a density of up to 0.05 g / cm 3 .
  • This water needled, voluminous fleece is also a product of this invention. This also applies to the use according to the invention. It's going on referred to the claims.
  • This method of making a consolidated voluminous nonwoven is first only applied to one side of the fleece.
  • the back (support side) has a different surface structure after the hardening treatment. Should both Sides should be structured and surface treated the same way to feed the other side of the fleece to another water needling machine. However, this has to do with the basic single treatment procedure None to do. A different product is required for double-sided needling, the but also falls under the scope of protection of the patent.

Claims (9)

  1. Procédé pour la consolidation d'une nappe fibreuse faite de fibres synthétiques, telles des fibres de polyester, de polyéthylène ou de polypropylène, et/ou de filaments, et/ou de fibres naturelles, qui sur une épaisseur de 10 mm et plus est fabriquée sans fibres de liage, telles que des fibres en fusion à deux composants ou des fibres en fusion spéciales, et sans liants, caractérisé en ce que pour obtenir une nappe fibreuse volumineuse, mais quand même consolidée transversalement, une nappe faite de fibres ayant un titre compris entre 1 et 15 deniers et un poids pouvant atteindre 200g/m2 est consolidée uniquement grâce à un aiguilletage par eau unique avec une pression hydraulique de maximum 60 bars, de préférence de 20 à 30 bars, appliquée uniformément sur la surface de la nappe et présente alors une densité pouvant atteindre 0,05 g/cm3.
  2. Procédé suivant la revendication 1, caractérisé en ce que cette technique de l'aiguilletage par eau pour obtenir une structure superficielle uniforme sur les deux faces de la nappe est répétée deux fois, et ce successivement aussi sur l'envers de la nappe.
