Definitions

  • the present invention relates to processes and machines for the production of nonwovens, consisting of fibers or filaments made of an organic material, in particular fibers or natural, synthetic or artificial textile filaments.
  • the fibers or filaments may be in particular polypropylene, polyester, or another plastic material and mixtures thereof.
  • a process for producing a nonwoven is already known in which a web in displacement of filaments or fibers at a compaction station is compacted in the direction of thickness.
  • the compaction is obtained by passing the web moving in the nip between two moving elements moving in the same direction.
  • One of the movable elements may be a conveyor or a cylinder and the other may also be a conveyor or a cylinder.
  • Downstream of the compaction station the compacted tablecloth is consolidated into a consolidated sheet at a consolidation station.
  • the consolidation can be carried out by mechanical needling, by chemical or thermal bonding. Hydraulic binding is preferably used by jets of water.
  • the nonwovens obtained have a ratio of a property in the long direction, and in particular of the tensile strength, to the same property in the cross direction, which is much greater than one.
  • the long direction is defined by the direction in which the web moves when it is sent to the compaction station, while the cross direction is the direction perpendicular to this direction in the plane of the web.
  • it would be desirable to reduce the ratio of a non-woven property. in the long direction to this property in the transverse direction whereas the production processes of veils, sheets and webs preferentially orient the fibers or filaments in the long direction, while having a high speed of displacement and synonymous with great productivity.
  • the invention provides for this by a process for producing a nonwoven in which a web of filaments or fibers is compacted in the direction of thickness at a point on its path of travel. a compacting station, and then consolidates the compacted web into a consolidated web at a consolidation station downstream, in the direction of travel of the web, the compaction station. According to the invention, the speed of movement of the web is reduced at the very point of its travel path where it is compacted.
  • the document GB 891143 discloses a method and a production machine according to the preambles of claims 1 and 8.
  • the property whose ratio is changed in the process according to the invention is preferably tensile strength, maximum at break, but it is also the tensile elongation or other tensile property. It has also been found that the process according to the invention makes it possible to improve the resistance of nonwovens to delamination.
  • the web is wetted at the compaction station or just downstream from this station.
  • wetting the deformation of the fibers of the web and thus retains the relationship between the property of the nonwoven in the long direction and the property of the nonwoven in the cross direction, is obtained at the compaction station, at the exit thereof while, without the fixation by wetting, the fibers tend, after they are no longer compacted to resume, at least in part, their initial orientation.
  • anchorage takes place before the arrival of the sheet at the consolidation station.
  • the sheet may be wetted by means of a hydraulic injector arranged in such a way that the jets extend substantially over the entire width of the sheet and by sending jets whose pressure is between 1 and 50 bars. .
  • this attachment may already have a certain consolidation effect, that is to say entanglement of the fibers. In some cases, it is wetted with a liquid other than pure water.
  • the compacted sheet is then consolidated into a consolidated sheet at the consolidation station, which is downstream in the direction of movement of the sheet of the compaction station and downstream from the point where the wetting of the sheet is carried out, if necessary.
  • the consolidation can be carried out by any known means, in particular by mechanical needling using metal needles, by chemical bonding, by thermal bonding using hot-melt fibers and by means of impregnation means such as scarf or spray or foam spray with a binder. But it is much preferred to carry out the consolidation by a hydraulic linkage by jets of water, if necessary also combined with other means of binding. Hydraulic binding can be carried out by jets of water of a diameter of between 50 and 250 microns at pressures of between 10 and 1000 bar.
  • the web is preferably a web of filaments from a machine operating in the melt or a web of fibers from a nonwoven card; it can also come from a machine operating aeraulic way called "air ugly” or a lapper-stretcher.
  • the invention applies in particular for surface masses of 0 to 500 g / m 2 and preferably 20 to 300 g / m 2 of the web.
  • the invention makes it possible in particular to produce filtration products, geotextiles, agrotextiles in civil engineering and construction, in the automobile, furniture, clothing, in medical applications, in roof seals, products soundproofing and thermal insulation, wiping products that are dry or impregnated for cleaning and hygiene.
  • the invention also relates to a machine for producing a nonwoven comprising a first element for sending a sheet to means intended to compress it in the direction of the thickness, characterized in that said means are also means for reducing the speed of movement of the web to the point where it is compacted by the compacting means.
  • the first element is preferably a conveyor, but it can also be a cylinder fed by a conveyor.
  • the compacting means are formed by the formation of a pinch point between the first element and another mobile element and the reduction in the speed of movement of the web is achieved by giving the other moving element a linear velocity less than that of the first element.
  • the other movable element may be a second conveyor or a second cylinder.
  • the nip preferably extends over the entire width of the web, relating to a whole generatrix of the pinch cylinder.
  • the machine comprises means for wetting the web while it is compacted or has just been compacted and before it arrives at consolidation means.
  • the consolidation means are arranged so as to consolidate the sheet while it passes over the other mobile element, since the consolidation is better as the speed of passage of the sheet to the consolidation station is smaller .
  • the invention relates to the use of a method or a machine according to the invention for reducing the ratio of a property of a nonwoven in the long direction to this property in the transverse direction and more particularly for to decrease the ratio of the tensile strength at break of a nonwoven in the long direction to this tensile strength at break in the cross direction.

  • the distance between the strand 7 and the lowest point of the cylinder 8 is so small that when a sheet is conveyed and passes on the strand 7, it comes into the nip between the strand 7 and the cylinder 8 and is compacted.
