Definitions
- the present invention relates to machines for producing nonwovens comprising one or more spun-bond towers and possibly one or more melt-blown heads depositing filaments and possibly fibers in a web on a conveyor.
- the tablecloth thus deposited and still fragile is then sent to consolidation by water jets.
- a disadvantage of these machines is that the web which leaves it cannot be sent continuously to a unit for applying a product.
- the invention overcomes this drawback.
- the invention therefore relates to a machine for producing a nonwoven continuously, comprising a spun-bond tower depositing filaments in a web on a conveyor and a device for consolidating the web, characterized by a means of expressing the humidity downstream, in the direction of movement of the sheet, of the consolidation device and by a device for applying a product to the sheet downstream of the expressing means.
- the expressing means is constituted simply by a second conveyor over which passes the sheet and between the upper and lower strands of which is provided a vacuum device, giving in particular a vacuum of between 40 and 700 millibar, subjecting the tablecloth has a suction effect.
- hydrophobic filaments for example polypropylene, polyethylene or metallocene
- a surfactant and / or a binder and / or a lubricating agent and / or a blowing agent and / or dye or continuous printing the expression of humidity being sufficient for the product applied by the application device to be applied correctly to the web even if it is made up of hydrophobic filaments .
- the upper strand of the second conveyor is given a length such, as a function of the speed of passage of the sheet, that the moisture content of the sheet becomes less than 70% by weight, and better still less than 50% and even better still less than 20% at the exit of the second conveyor.
- This moisture content is generally between 10% and 70% by weight. Unlike what drying would give, it is more than 10%.
- the length of time the web stays on the second conveyor can be less than 2 seconds for a conveyor whose upper strand has a length of 2 m for example.
- the machine can comprise downstream of the device for applying a product, a device for drying the sheet, this drying device being able to be made less consequent by the fact that a good part of the humidity has already been expressed the means of expression.
- the device for applying the product is preferably a device for applying to the foam, or to the licking roller or by spraying which accommodate a residual moisture content of the web.
- the application is made by longitudinal strips, which creates an alternation of hydrophilic and hydrophobic longitudinal zones for example.
- a spun-bond tower comprising an extruder of a molten organic polymer supplying a die 1 making it possible to produce a curtain of filaments F, a cooling zone 2 making it possible to obtain at least superficial solidification of the extruded filaments, a device 3 suction in the form of a chamber inside which the curtain of filaments is subjected to the action of high speed air streams which cause the drawing of the filaments, and a diffuser 4 allowing at the outlet of the suction device for deflecting and slowing down the air flow and distributing the filaments F randomly in a sheet deposited on the upper strand 5 of a first endless conveyor 6.
- the filaments are in the form of a bundle of filaments F, extending perpendicular to the plane of the figure.
- a horizontal drum 7 is mounted with a device symbolized by the letter A of depression inside.
- the lateral surface of the drum 7 is perforated.
- the drum is rotated relative to its axis.
- the drum is surrounded by a perforated sleeve.
- Two injectors 8 project jets of pressurized water onto the lateral face of the drum, the layer of filaments that can pass between the drum 7 and the injectors 8 and thus be consolidated.
- the jets can have a diameter between 80 and 170 microns.
- the number of jets per meter can be between 1,000 and 5,000 and the water pressure in the injectors can be between 10 and 400 bar, while the vacuum in the drum 7 can be between minus 20 millibar and less 200 millibar and the drum 7 can be driven at a speed between 1 and 400 m / min.
- the ply then passes over the upper strand 9 of a second conveyor 10 to go to a second drum 11 of the same structure and the same operation as the drum 7. From the drum 11, the ply passes over a drum 12 provided like the drum 11 injectors.
- the drum 12 is similar to the drum 11 in its structure and in its operation.
- the sheet is sent directly to a second conveyor 15 provided with a device 16 for expressing humidity, namely a box in which a vacuum of 600 millibar prevails and interposed between the upper strand and the lower strand of the second conveyor 15.
- the upper face of the box has a slit extending transversely opposite the entire web passing over the conveyor and through which the moisture from the latter is sucked.
- the upper strand has a length of 3 m.
- the sheet passes there at a speed of 200 m per minute.
- a device 17 for applying an ennobling product which comprises a station 18 for the actual application of the product, a station 19 for drying and a station 20 for winding. A ready-to-use nonwoven is thus obtained continuously.
