Definitions

  • the invention relates to a method for producing a spunbonded non-wovens. Moreover, the invention relates to an apparatus for carrying out such a method. It is within the scope of the invention that the continuous filaments consist of a thermoplastic material. Endless filaments differ because of their quasi-endless length of staple fibers, which have much smaller lengths of, for example, 10 to 60 mm. The continuous filaments are normally produced with a spinning device or with a spinnerette.
  • the invention has the technical problem of providing a method for producing a spunbonded nonwoven filaments, can be made with the thick or voluminous spunbonded nonwoven with a very regular or homogeneous structure.
  • the invention is based on the technical problem of specifying a corresponding device.
  • the invention teaches a method for producing a spunbonded nonwoven filament, wherein filaments are produced, at least part of which has a natural crimp, wherein the filaments are deposited in the storage area of a conveyor for filament storage and wherein the filament tray is conveyed by the conveyor in the direction of a solidification device and wherein a flowing in the conveying direction of the Filamentablage on the surface of the Filamentablage gas flow is generated.
  • single-layer or multi-layer spunbonded nonwovens can be produced within the scope of the invention, which consist entirely of filaments with natural crimping. However, it is also within the scope of the invention to produce a single-ply spunbonded fabric comprising a blend of natural crimp filaments and non-crimping filaments.
  • the individual layers can be formed from natural crimp or non-crimping filaments or blends of natural crimp filaments with non-crimping filaments.
  • a multilayer spunbonded web according to the invention comprises at least one layer consisting solely of natural crimp filaments or of a blend of natural crimp filaments with non-crimping filaments.
  • the endless filaments are first spun from a spinning device or from a spinnerette. Conveniently, then a cooling of these filaments. It is within the scope of the invention that the filaments are drawn in a drawing device. The cooling and Drawing can also take place in particular in a combined cooling and stretching device. Before the storage of the filaments in the storage area, they are preferably passed through a diffuser. The diffuser is then arranged between the drawing device or between the combined cooling and drawing device and the storage area.
  • the filaments emerging from the spinning device are preferably prepared by the Reicofil III process ( DE-PS 196 20 379 ) or according to the Reicofil IV method ( EP-OS 1 340 843 ).
  • filaments with natural crimping means filaments or bicomponent / multicomponent filaments in which crimping commences after drawing.
  • the crimping starts here as soon as the stretching forces or the air-stretching forces no longer act on the filaments.
  • the crimping can first take place before the deposit, ie between the drafting device and the storage area, in particular in a preferably provided diffuser.
  • This ripple, occurring before the filaments are deposited is called “primary rippling”.
  • the filaments with natural crimping can develop a (further) crimp in particular even after being deposited. This ripple occurring after placement is called “secondary rippling".
  • filaments with natural crimping preferably mean filaments which, after being deposited on the conveyor in the relaxed state, have radii of curvature of less than 5 mm. These filaments have over most of their length corresponding crimps with the aforementioned radii of curvature.
  • the filaments with natural crimping bicomponent filaments or multi-component filaments with side-by-side arrangement.
  • Multi-component filaments with an acentric core / shell arrangement can be used.
  • the inventive method is performed with the proviso that a crimping of the filaments (with natural crimping) takes place after a stretching of the filaments and before filing the filaments. This is therefore the already mentioned primary crimping of the filaments. It is also within the scope of the invention that a crimping of the filaments (with natural crimping) takes place after filing the filaments on the conveyor. This is the secondary ripple already mentioned above.
  • the conveyor expediently consists of a conveyor belt or of a plurality of successively connected conveyor belts.
  • at least one conveyor belt in the filing area of the filaments is designed as a gas-permeable (air-permeable) conveyor belt or gas-permeable (air-permeable) screen belt.
  • a screen belt is, in particular, an endless belt guided over deflection rollers.
  • the filaments are deposited on a wire belt as a conveyor or as part of a conveyor for filament storage and the filament tray is acted upon in a suction region of the wire with suction air.
  • the suction region comprises the storage area for the filaments and expediently also an area in the conveying direction behind this storage area.
  • at least one suction device is preferably arranged below the screen belt. With such a suction device, air is sucked through the screen belt, so that, as it were, the filaments or the filament deposit is sucked onto the screen belt. This results in a certain stabilization of the Filamentablage. Due to this Saugbeetzschlagung points the filament tray a relatively small thickness (for example, a thickness of about 2 to 3 mm).
  • the filament tray In this suction area, the filament tray is (still) fixed and held down by a suction air field on the screen belt to survive the relatively high air velocities in the storage area without unwanted displacements and inhomogeneities.
  • the suction area When the suction area is left, the filament tray jumps on, in particular due to the secondary crimping. Thereafter, the Filamentablage has a much higher thickness (for example, a thickness of 3 cm at 40 g / m 2 basis weight).
  • a gas flow flowing along in the conveying direction of the filament deposit on the surface of the filament deposit is generated.
  • the fact that the gas stream flows along the surface of the filament deposit means, in particular, that the gas stream flows parallel or substantially parallel to the surface of the filament deposit or flows parallel or substantially parallel to the surface of the expectoration device or of the screen belt. It is within the scope of the invention that the gas stream flows past in the conveying direction behind the suction on the surface of the filament tray.
  • the gas stream is preferably an air stream.
  • the filament deposit jumps on leaving the suction area, in particular because of the secondary crimping as it were and then results in a relatively thick Filamentablage.
  • the invention is based on the recognition that this Filamentablage is at risk when jumping or in the cracked state, on the one hand, because shrinkage forces from the secondary ripples can destroy the uniformity of Filamentablage and on the other hand because air forces act on theticianprurgede Filamentablage and this Filamentablage quasi can open. These air forces result from the fact that the Filamentablage is at the speed of the conveyor or the screen belt as it moves against standing ambient air.
  • the filament deposit is stabilized in particular in the suction-free regions by an imposed air flow.
  • the flow velocity of the gas stream (air stream) corresponds to at least half the conveying speed of the filament deposit, preferably at least 80%, preferably at least 90% and very preferably at least 95% of the conveying speed of the filament deposit.
  • the flow velocity of the gas stream (air stream) corresponds at least to the conveying speed or approximately the conveying speed of the filament deposit.

  • the filament deposit is solidified in the solidification device with at least one fluid medium, preferably with at least one hot fluid medium. It is within the scope of the invention that the filament deposit in the solidification device with the hot fluid medium is acted upon with the proviso that the filament tray is pressed against the conveyor or against a gas-permeable screen belt. In this case, a transverse loading of the Filamentablagenober Assembly is advantageously carried out by the forces of the hot fluid medium. As a result, the Filamentablage to the conveyor or to the Pressed sieve belt. It is within the scope of the invention that the hot fluid medium flows through the Filamentablage and the gas-permeable screen belt.

  • the solidification is carried out as hot air solidification.

It is within the scope of the invention that the Filamentablage of the fluid medium, preferably from the hot fluid medium in terms of area (ie, not only linear) is applied.
