Definitions

  • the invention relates to a method for producing a one-layered or multilayered nonwoven fabric, as disclosed in the preamble to claim 1 , as well as the apparatus for producing such a nonwoven fabric and also a correspondingly produced nonwoven fabric.
  • a nonwoven fabric composed of a plurality of yarn-type fiber groups is already known (EP 0 626 902 B1), wherein these groups are joined at connecting points through fibers belonging to a plurality of these groups to delimit a predetermined pattern of holes in the nonwoven fabric, wherein the nonwoven fabric has a transparency index of at least 0.5 and a computed fiber bundle density of at least 0.14 gram per cubic centimeter.
  • the object of the present invention to improve a production method and a production apparatus in accordance with the respective preamble.
  • the goal advantageously is to prevent loops or fibrils from sticking out of the nonwoven fabric, thereby preventing the pulling out of individual filaments during the use of the nonwoven fabric.
  • the nonwoven fabric preferably is a spun-bonded fabric that is subjected to a hydrodynamic needling technique, is subsequently dried, and is then smoothed with the aid of a calender.
  • the loops or fibrils that stick out and are extremely bothersome when using a one-layer or also a multilayer nonwoven fabric are welded-on in an easy operation by the calender and are simultaneously smoothed, so as to avoid the pilling effect or the nap or lint forming.
  • the apparatus advantageously includes a spun-bonding plant by means of which the filaments are deposited onto an endless belt that is embodied as a screen belt, as well as at least one downstream-connected needling device, an adjoining dryer, and at least one calender following the dryer.
  • the apparatus can optionally comprise a spun-bonding plant, a downstream-connected pre-needling device that can be admitted with low water pressure, an adjoining second needling device with thereto assigned at least one structuring drum with a suction box, as well as an adjoining dryer and at least one calender that follows the dryer.
  • the apparatus includes a spun-bonding plant with downstream-connected pre-needling device that can be admitted with low water pressure, a following second needling device with at least one structuring drum, an adjoining dryer, and at least one calender following the dryer.
  • the apparatus is advantageously also provided with a spun-bonding plant, by means of which the filaments are deposited on the structuring drum, as well as the needling device that is directly assigned to the structuring drum, the adjoining dryer and at least the calender following the dryer.
  • the apparatus comprises the spun-bonding plant with downstream-connected pre-needling device that can be admitted with low water pressure, the adjoining second needling device that is provided with at least one structured drum, and a calender following the second needling device.
  • At least one conveying drum is assigned to the structured drum, such that the endless belt is guided S-shaped or in the form of two semi-circles across the structured drum and the conveying drum.
  • the endless belt can advantageously be embodied as a conveyor belt or as a structured belt.
  • the invention relates to one-layer or multilayer nonwoven fabrics which are additionally and advantageously perforated by using one of the water needling processes.
  • Nonwoven fabrics having a weight per unit area of 7-300 g/m 2 are preferably processed.
  • the processing speed is at least 100 m/min while the fiber strength—filament strength—preferably ranges from 0.4 to 10 dtex.
  • FIG. 1 A schematic representation of a spun-bonding plant with a downstream-arranged rotating belt on which the filaments are deposited, as well as a needling device, a dryer and a calender;
  • FIG. 2 A similar representation as shown in FIG. 1 , for which the endless belt is guided S-shaped or in the form of two semi-circles over the drums;
  • FIG. 3 A similar representation as shown in FIG. 1 , but where the endless belt is replaced by a drum;
  • FIG. 4 A similar representation as shown in FIG. 1 , for which the endless belt is embodied only as a conveying element;
  • FIG. 5 A segment of the endless belt or a segment of a structured drum on which the filaments are deposited;
  • FIG. 6 A nonwoven fabric with numerous openings, which is processed on the endless belt.
  • the drawing shows a spun-bonding plant 1 , which is used for depositing and further transporting endless filaments 4 on a continuously rotating belt 3 that is guided over four rollers 2 , wherein at least one of the four rollers 2 is embodied as a drive roller.
  • the endless belt 3 is shown in further detail in FIG. 5 .
  • This belt is a screen belt composed of webs or wires 5 , arranged spaced apart and extending at right angles to each other, between which small and approximately rectangular openings 6 are formed that allow the water 8 exiting from a needling device 7 . 1 to flow through these openings 6 .
  • the screen belt 3 Owing to the screen belt 3 , the water is forced to travel longer distances and the individual filaments are displaced to the side, as shown in FIG. 6 , thereby causing corresponding openings 6 . 1 to form in a nonwoven fabric 14 , which openings match the shape of the openings 6 in the endless belt 3 .
  • the nonwoven fabric 14 moves through a dryer 9 , which can be embodied as infrared inline airflow dryer.
  • the nonwoven fabric 14 is then smoothed with the aid of a calender 10 , so that any filaments or loops or fibrils that still stick out are pushed back into the nonwoven fabric 14 .
  • the projecting loops or fibrils are welded on and are simultaneously also pushed against the surface of the nonwoven fabric 14 .
  • the nonwoven fabric 14 is supplied by the endless belt 3 to the water needling device 7 . 1 with a suction box 7 . 3 , so that at this location the nonwoven fabric 14 can be roughly pre-compacted with low pressure.
  • the nonwoven fabric 14 is compacted in such a way that it can subsequently be guided S-shaped or in the form of two semi-circles across two drums 11 and 12 , wherein the second drum 12 is assigned an additional needling device 7 . 2 with a suction box 7 . 3 .
  • FIG. 1 the water needling device 7 . 1 with a suction box 7 . 3
  • the nonwoven fabric is taken over by the lower drum with the aid of suction pressure, is thus lifted off the screen belt with the aid of the drum 11 and is subsequently taken over by the drum 11 and, in the process, is transferred S-shaped to the drum 12 with thereto assigned suction box 7 . 3 .
  • the nonwoven fabric 14 is thus pushed against the drum 12 .
  • the first drum 11 is a conveying drum while the second drum 12 is a structured drum, which corresponds to the endless belt 3 , shown in FIG. 1 , and is provided with numerous openings 6 corresponding to the screen belt or endless belt 3 shown in FIG. 5 .
  • the endless belt according to FIG. 2 is not embodied as a perforated belt, but only as a conveyor belt.
  • the nonwoven fabric 14 is deposited on the conveyor belt 3 , is then transferred to the drum 11 and is held thereon with the aid of a vacuum pressure.
  • the perforation-creating openings provided in the drum 12 are thus used to create the openings 6 . 1 shown in FIG. 6 in the nonwoven fabric 14 , with the aid of the water needling device 7 . 1 , 7 . 2 .
  • the endless belt system according to FIG. 1 is replaced by a structured drum 13 with the needling device 7 . 1 and the suction box 7 . 3 .
  • the exemplary embodiment shown in FIG. 4 does not comprise the dryer 9 between the two deflection drums 11 , 12 and the downstream connected calenders 10 .
