Definitions

  • the present invention relates to methods and production facilities for nonwovens. More particularly, the invention is relates to the production of nonwovens using a spun-bond tower depositor a web of filaments on a first conveyor.
  • the invention improves the method and the installation described in U.S. Patent No. 3,485,706 to obtain a nonwoven having better properties.
  • the subject of the invention is therefore a method for conserving the ratio of the tensile strength in the long direction to the resistance to traction in the cross direction of a moving web of filaments, characterized in that the web is subjected to depression by applying it on a support during the passage of a conveyor to a movable element.
  • the movable element may be a second conveyor or a cylinder or hollow drum.
  • this can even be improved. ratio by giving the support which has the shape of a second movable element a linear speed less than that of the first conveyor.
  • the invention also aims at a production facility of a nonwoven comprising a spun-bond tower depositing a sheet of filaments on a first conveyor, the web being sent to a first element mobile to means of consolidation by entanglement.
  • means are provided for passing, without modifying the ratio of the tensile strength in the long direction to the resistance to traction in the cross direction, the filament web on the first element mobile.
  • Said means comprise a second movable element having a vacuum device holding the web on the surface exterior of the second movable member.
  • the second movable member may be a drum or a conveyor.
  • the first conveyor is more permeable to air than the first movable member.
  • the first 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 in air from 50 to 500 (1.41 m 3 / min at 14.1 m 3 / min).
  • the first conveyor (2) is generally a fabric synthetic double or triple layer with antistatic properties and a strong roughness.
  • the second movable member (5) is a synthetic fabric or metallic single-layer frame canvas, twill or satin and low roughness
  • the first conveyor is rougher than the second movable element.
  • the first conveyor directly sends the sheet to the means intended to make pass the sheet of filaments on the first movable element.
  • the invention finally relates to the use of a method or a according to the invention to maintain the ratio of the resistance to traction in the long direction to the tensile strength in the cross direction a moving web of filaments.
  • the single figure is a schematic view of an installation producing a nonwoven. It includes a 1 spun-bond tower.
  • a tower spun-bond comprises a device for extruding polymers, in particular polypropylene or polyester, which leads into a die giving polymer filaments which are then cooled in a cooling, then always in the downward direction, stretched in a drawing device and deposited in the form of a tablecloth on a first endless conveyor 2 having good air permeability and relatively rough so that the filaments are deposited without slipping on its area.
  • the upper strand of the conveyor 2, on which is deposited the sheet of filaments passes in the nip between two rollers 3 pressers constituting a compacting device. These pressure rollers have been shown in dashes in the figure because they are optional.
  • first conveyor 2 At the exit of first conveyor 2, the sheet passes over a hollow drum 4 (second element mobile) within which there is a depression, so that the tablecloth is applied to the lower part of the drum 4 and that the properties of the tablecloth do not change as would be the case if it passed directly from one conveyor to another with the ensuing tensile phenomena.
  • the web is taken up by a conveyor 5 (first mobile element), and goes under consolidation devices 6 by projection of water jets with a diameter of between 50 and 250 microns and 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 breathable than the conveyor 2.
  • the return roller 7 of the conveyor 5, which is the closest 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 in the counterclockwise at a linear speed smaller than the speed of movement of the conveyor 2 from left to right at the Fig.
