Definitions

  • the invention relates to a method for producing a Spunbonded web of multicomponent filaments.
  • - Multi-component filaments means filaments that consist of several consist of different thermoplastic materials and bicomponent filaments means filaments consisting of two consist of different thermoplastic materials.
  • the cross-sectional area of such a filament is thereby partly from a first thermoplastic formed and in part of at least a second thermoplastic Plastic. This distribution of different Plastics usually extends over the entire length of the filament.
  • the invention is the technical problem to provide a method of the type mentioned above, with the spunbonded webs or spunbonded nonwovens can be produced, the excellent mechanical Have properties, in particular a high bulkiness and with those properties especially very are reproducibly adjustable.
  • the invention teaches a method for producing a spunbonded web of multicomponent filaments, wherein the multicomponent filaments are deposited on a support to the spunbonded web, wherein the spunbonded web is solidified as a single nonwoven web by water jet treatment with high pressure water jets, and wherein the spunbonded web is subjected to a heat treatment after the water jet reinforcement to activate a filament crimp.
  • Filaments means in the context of the invention endless threads thermoplastic material, the spunbonded web be filed. Basically, under the Invention but also shorter fibers for the production of Spunbonded web be used. In that regard, he means Term filaments according to one embodiment also shorter Fibers.
  • bicomponent filaments After a very preferred embodiment of the invention will worked with bicomponent filaments.
  • the bicomponent filaments So there are two different thermoplastic Plastics with different properties, in particular with different expansion behavior or shrinkage behavior. Bicomponent filaments have become especially proven for the process according to the invention.
  • Multi-component filaments used with side-by-side structure are very preferred.
  • Multi-component filaments used with side-by-side structure is very particularly preferred.
  • Bicomponent filaments with side-by-side structure there along the length of the filaments becomes part of the Filament surface formed by a first polymer and the other part of the filament surface of a second Polymer.
  • the use of bicomponent filaments in side-by-side arrangement has become with regard to the solution of technical problem particularly well-tried and surprising, further down mentioned benefits.
  • the multicomponent filaments or bicomponent filaments be with a suitable nozzle head or with a suitable spinnerette made. It lies within the framework of Invention that the exiting filaments are cooled. It is further within the scope of the invention that the Filaments are stretched. Appropriately, the Filaments on an endless revolving filter belt filed tray deposited to spunbonded web.
  • the Spunbonded web subsequently to activate a Filamentk Hurselung subjected to a heat treatment. Due to the different shrinkage behavior of the polymers, from those the multicomponent filaments or the bicomponent filaments exist, arises through the heat treatment or thermal treatment a ripple.
  • the heat treatment as Hot air treatment performed. The rippling of the Filaments in the spunbonded web will be so with help activated by hot air.
  • Hot air treatment means in particular a treatment with air at a temperature about 60 ° C.
  • the invention is based on the finding that with the process according to the invention optimum mechanical properties, in particular a high bulkiness of the spunbonded web can be achieved and adjusted.
  • Special Importance is the combination of hydroentanglement on the one hand and downstream heat treatment, in particular hot air treatment on the other hand to.
  • Have proven particularly in the context of inventive method bicomponent filaments with Side-by-side structure.
  • the invention is the realization underlying that with an inventive Hydroentanglement very reliable and targeted large free filament lengths can be adjusted.
  • the invention differs Method of other known from the prior art Consolidation measures. After solidification with more targeted Setting the free filament lengths is then at the downstream heat treatment, preferably hot air treatment, the filament crimp is activated due to the different expansion properties of the polymers comes about.
  • Free Filament length means by the way the length of a Filament section between two solidification points.
  • Hot air treatment can be a surprisingly high Rippling effect can be achieved and, above all, targeted be set.
  • Fig. 1 shows a in the context of the method according to the invention preferably used bicomponent filament with side-by-side structure.
  • the polymer A is half the cross-sectional area of the Filament and the polymer B forms the other half this cross-sectional area.
  • This arrangement extends preferably over the entire length of the filament. It It is understood that the polymer A or the polymer B also a larger part of the filament cross-sectional area can take.
  • Fig. 1 shows so far only one possible Embodiment of a bicomponent filament with side-by-side structure.
  • the polymers A and B have suitably different shrinkage properties or expansion properties.
  • Fig. 2 shows very schematically a device for Implementation of the method according to the invention.
  • the Filaments 1 are on one as endless circulating Ablegesiebband 2 trained tray for spunbonded web 5 stored.
  • the spunbonded web 5 is on the Ablegesiebband 1 moves in the direction of arrow C.
  • a solidification device 3 a nonwoven bonding takes place Water jet treatment or by treatment with high pressure water jets.
  • the filament crimp is in a heat treatment device 4 activated, in which the spunbonded web 5 with hot air is charged.
  • the device became very much in Fig. 2 simplified and it is understood that more Procedural measures and device components provided or can be interposed.
