Definitions

  • the invention relates to a method for producing a nonwoven fabric wherein a nonwoven fabric layer is formed from a fiber mixture of at least two different fiber types.
  • the fibers are preferably filaments of thermoplastic material.
  • WO 02/31250 A describes a method for producing spunbonded nonwovens, wherein at least a first and a second filament is used and wherein at least one filament consists of several components. Furthermore, in WO 02/31250 A Solidification measures for the spunbond called. EP 0 181 300 A also discloses a process for producing spunbond webs using different filaments.
  • WO 03/040452 A relates to a process in which spunbonded nonwovens are made from staple fibers. In this case, a mixture of elastomeric staple fibers and crimped Bikomponentenstapelfasem is used.
  • US 3,917,448 A also deals with a process for the production of spunbond webs, wherein different nonwoven layers are joined together by the further introduction of filaments.
  • US 5,853,635 A and US 5,965,468 A In addition, methods are known in which spun nonwovens are produced from multi-component fabrics.
  • US 5,028,375 A also relates to a spunbonding process wherein the spunbonded web produced by this process consists of only a single type of fiber.
  • the invention is based on the technical problem to provide a method of the type mentioned, with the volume or the thickness of a nonwoven fabric can be increased from Mehrkomponentenfilêtn in a simple and inexpensive manner.
  • the invention teaches a method for producing a nonwoven fabric, wherein a nonwoven layer is formed from a fiber mixture of monocomponent filaments, wherein this fiber mixture consists of at least two different types of fibers of monocomponent filaments and wherein the two types of fibers have a different shrinkage behavior during a heat treatment, wherein the different types of fibers forming the nonwoven layer are produced with a single spinning tool, wherein the single nonwoven layer is solidified, and wherein the solidified single nonwoven layer is subsequently subjected to a heat treatment with the proviso that the shrinkage of at least one of the fiber types is activated.
  • a single nonwoven layer is meant according to an embodiment of the invention, a layer aggregate, which is formed from a plurality of identical nonwoven fabric layers.
  • a plurality of identical nonwoven fabric layers with identical fiber mixtures and thus identical shrinkage properties are formed one above the other, so that a homogeneous layer aggregate is formed as it were.
  • these forming the bearing unit identical nonwoven fabric layers are produced with a spinning tool and all on the same tray.
  • such a layer aggregate also forms a single nonwoven layer, which is subsequently solidified, preferably solidified in a calender.
  • the fibers of the fiber mixture are continuous fibers which expediently consist of thermoplastic material.
  • the only nonwoven layer before solidification is in the form of a homogeneous fiber mixture.
  • the at least two fiber types are homogeneously distributed in the nonwoven fabric layer.
  • Homogeneous in this context also means that the fibers are distributed substantially homogeneously in the nonwoven layer. In any case, it is within the scope of the invention that no different layers or layers are formed with the different fiber types.
  • the two fiber types of the fiber mixture have a different shrinkage behavior during a heat treatment.
  • the fiber mixture used in the context of the invention So it is a shrinkable fiber mixture whose various types of fibers shrink at different temperatures.
  • the different types of fibers forming the nonwoven fabric layer are produced with a single spinning tool.
  • a nonwoven fabric layer according to the invention is thus prepared according to this embodiment, advantageously in a spinning shaft as Mischfaserablage.
  • a spinning tool is used in the context of this embodiment, which normally serves for the production of bicomponent fibers or multi-component fibers.
  • the different components or the different fiber types emerge from respectively different spinning openings or capillaries of the spinning tool. An approximately equal spinning speed of the different components or the different fiber types can be ensured by varying the respective hole densities and throughputs per capillary.
  • the two fiber types consist of different plastics.
  • at least one of the two types of fibers consists of at least one plastic from the group "polyolefin, polyester, polyamide".
  • the two types of fibers can also consist of copolymers of these plastics.
  • the first type of fiber is a polyolefin and the second type of fiber is a polyester.
  • the polyolefin is expediently polyethylene or polypropylene.
  • the polyester is preferably polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).
  • one type of fiber of the fiber mixture consists of polypropylene and the second type of fiber of the fiber mixture consists of polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • Another embodiment of the invention is characterized in that a Fiber type of the fiber mixture consists of polypropylene and the second type of fiber consists of polybutylene terephthalate (PBT).
  • PBT polybutylene terephthalate
  • the first type of fiber of the fiber mixture consists of polyethylene and the second type of fiber of the fiber mixture consists of polypropylene.
  • the fibers used for the fiber mixture are according to the invention monofilaments. In principle, however, it is also within the scope of the invention for a type of fiber of the fiber mixture to consist of multicomponent fibers or multi-component filaments and in particular of bicomponent fibers or bicomponent filaments. However, the use of monofilaments for the two or for all fiber types of the fiber mixture is preferred.
  • the two fiber types of the fiber mixture have a different shrinkage behavior during a heat treatment. Due to appropriate selection of the raw material for the fibers and / or by adjusting the spinning conditions, the different fiber components have different shrinkage potentials in a certain temperature range.
  • the single nonwoven fabric layer is solidified with a calender.
  • a calender roll or a pair of calender rolls is used for solidification.
  • a calender roll or calender roll pair is used which has engraving points with engraving point intervals of more than 1.5 mm, preferably more than 2.5 mm. According to a preferred embodiment, these are mean engraving point distances.
  • the heat treatment of the consolidated nonwoven fabric layer is carried out with the aid of a heated or heated fluid.
  • the heat treatment is carried out with the aid of hot air.
  • the heat treatment can be performed in a hot air oven.
  • a drum dryer can be used.
  • the different shrinkage of both types of fibers is utilized.
  • the fiber component with the higher shrinkage pulls together the engraving points or connection points, while the fiber component with the smaller shrinkage has to dodge into the thickness.
  • the invention is based on the finding that voluminous nonwovens can be produced with the method according to the invention in a simple and inexpensive manner, which are distinguished by excellent properties. This gives relatively thick and voluminous nonwovens with excellent textile feel. It should be emphasized that the process can be carried out in a relatively inexpensive manner and thus also the nonwovens produced are characterized by cost-effectiveness.
