Definitions

  • the present invention relates to processes and facilities for producing nonwovens. More particularly, the invention relates to the production of nonwovens using a spun-bond tower depositing a sheet of filaments on a first conveyor.
  • the invention makes it possible to obtain a nonwoven having better properties in a spum-bond tower,
  • the invention therefore relates to a method as defined in the Rev. 1
  • the transport element may be a second conveyor or a hollow cylinder or drum.
  • this ratio can even be improved by giving the support which has the shape of a second transport element a linear speed less than that of the first conveyor.
  • the invention also relates to a plant for producing a nonwoven fabric comprising a spun-bond tower depositing a sheet of filaments on a conveyor, the sheet being sent on a first transport element to entanglement consolidation means. as defined in Rev. 3.
  • Said means comprise a second transport element having a vacuum device holding the web on the outer surface of the second transport element.
  • the second transport element may be a drum or a conveyor.
  • the first conveyor is more permeable to air than the first transport element.
  • the conveyor has, for example, an air permeability of 500 to 1100 CFM (14.1 m 3 / min at 31 m 3 / min.) While the second movable element has a permeability to air from 50 to 500 (1.41 m 3 / min to 14.1 m 3 / min).
  • the conveyor (2) is generally a double or triple layer synthetic fabric with antistatic properties and a high roughness.
  • the second transport element (5) is a synthetic fabric or metal single-layer canvas, twill or satin reinforcement and low roughness
  • the first conveyor is rougher than the second conveyor.
  • the first conveyor directly sends the sheet to the means for passing the filament web on the first transport element.
  • the single figure is a schematic view of a production facility of a nonwoven. It includes a 1 spun-bond tower.
  • a spun-bond tower comprises a device for extruding polymers, in particular polypropylene or polyester, which opens into a spinneret giving filaments of polymers which are then cooled in a cooling device, then always in the downward direction, stretched in a drawing device and deposited in the form of a web on a first endless conveyor 2 having a good air permeability and relatively rough so that the filaments are deposited without sliding on its surface.
  • the upper strand of the conveyor 2, on which the filament web is deposited passes into the nip between two pressure rollers 3 constituting a compacting device.
  • the pressure rollers have been shown in dashes in the figure because they are optional.
  • the sheet passes over a hollow drum 4 (second conveying element) inside which there is a depression, so that the sheet is applied to the lower part of the drum 4 and the properties of the the sheet does not change as it would be if it passed directly from one conveyor to another with the ensuing tensile phenomena.
  • the web is taken up by a conveyor 5 (first transport element), and passes under devices 6 consolidation by jetting water jets with a diameter between 50 and 250 microns and at a pressure between 20 and 1000 bar and water is projected by these devices 6 on the web and entangling the fibers.
  • the conveyor 5 is less permeable to air than the conveyor 2.
  • the return roller 7 of the conveyor 5, which is the closest to the suction cylinder 4, can also be provided with a suction to facilitate the passage of the web of the drum 4 to the conveyor 5.
  • the drum 4 rotates counterclockwise at a linear speed smaller than the speed of movement of the conveyor 2 from left to right in the figure.
