Definitions

  • the invention relates to a method for producing a spunbonded web of bicomponent filaments.
  • - Bicomponent filaments means filaments made of two different thermoplastics. The cross-sectional area of such a filament is partially formed by a first thermoplastic material and partly by at least one second thermoplastic material. This distribution of the different plastics usually extends over the entire length of the filament.
  • spunbonded nonwoven webs often result, which are not very useful with regard to the desired properties, and so far many of these processes are characterized by a disadvantageously high rejection rate.
  • the invention addresses the technical problem of providing a method of the type mentioned, can be made with the spunbonded webs or spunbonded nonwovens, which have excellent mechanical properties, especially a high bulkiness and with these properties are very reproducible above all adjustable.
  • the invention teaches a method for producing a spunbonded web of bicomponent filaments according to claim 1.
  • Filaments means in the context of the invention continuous filaments of thermoplastic material, which are stored to the spunbonded web. In principle, however, shorter fibers can also be used for producing the spunbonded nonwoven web within the scope of the invention. In that regard, the term filaments according to one embodiment also means shorter fibers.
  • the bicomponent filaments consist of two different thermoplastic materials with different properties, in particular with different expansion behavior or shrinkage behavior. Bicomponent filaments have proven particularly useful for the process of the invention.
  • bicomponent filaments with side-by-side structure are used.
  • part of the filament surface is formed by a first polymer and the other part of the filament surface by a second polymer.
  • the bicomponent filaments are produced with a suitable nozzle head or with a suitable spinnerette. It is within the scope of the invention that the exiting filaments are cooled. It is also within the scope of the invention that the filaments are drawn. Advantageously, the filaments are deposited on a trained as endless circulating Ablitissiebband storage for spunbonded web.
  • the spunbonded web is then subjected to a heat treatment to activate filament crimping. Due to the different shrinkage behavior of the polymers that make up the bicomponent filaments, a crimping is produced by the heat treatment or thermal treatment.
  • the heat treatment is carried out as a hot air treatment.
  • the crimping of the filaments in the spunbonded web is thus activated by means of hot air.
  • Hot air treatment means in particular a treatment with air at a temperature above 60 ° C.
  • the invention is based on the finding that with the method according to the invention optimum mechanical properties, in particular a high bulkiness of the spunbonded nonwoven web, can be achieved and adjusted. Of particular importance is the combination of hydroentanglement on the one hand and downstream hot air treatment on the other.
  • bicomponent filaments with side-by-side structure have proven particularly useful.
  • the invention is based on the finding that with a hydroentanglement according to the invention very reliable function and targeted large free filament lengths can be adjusted. Already in this respect, the method according to the invention differs from other known from the prior art solidification measures.
  • the filament crimp is then activated in the downstream hot air treatment, which comes about due to the different expansion properties of the polymers. Due to the targeted and reproducible setting of the free filament lengths of the bicomponent filaments possible during the hydroentanglement, the filament crimp can then be activated during the heat treatment in such a way that a nonwoven with surprisingly high bulkiness is obtained.
  • free filament length means the length of a filament section between two solidification points.
  • Fig. 1 shows a preferably used in the context of the method according to the invention bicomponent filament with side-by-side structure.
  • the polymer A forms half of the cross-sectional area of the filament and the polymer B forms the other half of this cross-sectional area.
  • This arrangement preferably extends over the entire length of the filament. It is understood that the polymer A or the polymer B can also occupy a larger part of the Filamentqueritess simulation.
  • Fig. 1 In this respect, only one possible embodiment of a bicomponent filament with side-by-side structure is shown.
  • the polymers A and B expediently have different shrinkage properties or expansion properties.
  • Fig. 2 shows very schematically a device for carrying out the method according to the invention.
  • the filaments 1 are placed on a trained as endless circulating Ablegesiebband 2 filing the spunbonded web 5.
  • the spunbonded web 5 is moved on the Ablegesiebband 1 in the direction of arrow C.
  • a web consolidation takes place by water jet treatment or by treatment with high-pressure water jets.
  • the filament crimp is activated in a heat treatment device 4, in which the spunbonded web 5 is acted upon by hot air.
  • the device was in Fig. 2 shown very simplified and it is understood that further procedural measures and device components may be provided or interposed.
