Definitions
- the present invention relates to an improved installation for the manufacture of a nonwoven textile web, commonly known by the generic name of "spunbond” and which is formed by continuous synthetic filaments
- the web is consolidated, for example by performing a calibration or calendering, preferably hot, so that the elementary filaments are linked to each other.
- consolidation treatments can also be carried out, such as for example a needling treatment (conventional or by jets of fluid), and / or the deposition on the surface or inside the sheet of a material. binding.
- these receive an electrostatic charge which can be obtained by an electrostatic generator causing a Corona type effect located upstream or downstream of the suction nozzle.
- US Pat. No. 4,064,605 describes an improvement to such a technique which consists in providing an additional assembly for cooling the filaments, before introduction into the drawing chamber proper, by subjecting the bundle of filaments to a transverse air flow.
- stretching the filaments coupled with high productivity, also means being able to brake the air streams at the outlet of the stretching slot to obtain a regular deposition of the filaments on the receiving conveyor and the production of a good quality sail.
- the installation according to the invention is of the type comprising conventionally:
- a suction device in the form of a chamber of rectangular section, of small width, inside which the curtain of filaments is subjected to the action of high speed air streams causing drawing of the filaments;
- the installation according to the invention is characterized in that the means making it possible to carry out the different operating phases, namely extrusion means, cooling means, filament drawing assembly and distribution means, are separated from each other. others and can be adjusted independently, not only depending on the production to be carried out (nature of the polymers, elementary titer of the filaments produced, grammage of the sheet produced), but also during the production launch phase.
- the cooling zone at the outlet of the die and the stretching zone of the filaments consists of a plurality of elementary modules juxtaposed to each other according to the production width, the filament opening system being, for its part , consisting of an assembly extending over the entire width of the sheet produced;
- the filament stretching device has a suction slot, the width of which can be adjusted automatically depending on the start of production of the machine.
- the filament opening system which is spaced from the outlet of the drawing system is made up of an assembly which laterally deflects the air flow, reducing the speed of this and that of the filaments, and facilitating uniform deposition advantageously, the filament opening system is also associated with an assembly electrostatically charging said filaments before deposition on the receiving belt and which can be placed either immediately at the exit of said system. opening or integrated inside the latter;
- the installation includes means of computer control of all the sub-assemblies allowing the production line to speed up automatically.
- the invention also relates to a method for implementing such an installation, a method which is characterized in that:
- the air temperature inside each cooling zone decreases from one zone to the next, the speed of the air passing through each zone being adjustable and can be between 0 , 5 m / second and 3 m / second in each of said zones, the stretching slot being maintained in the separated position,
- the parameters of the zone for cooling and warming up the filaments being modified to: increase the air speed of the first zone, the temperature remaining unchanged, increase the temperature of the second zone to bring it to that of the first zone and increase the air speed of this zone, increase the air temperature of the third zone and increase the air speed of this zone;
- the width of the stretching slot is gradually reduced to reach a nominal operating value, the pressure of the stretching air being gradually increased.
- the temperature of the air inside each cooling zone is generally within a range which can range from 5 ° C. to 60 ° C.
- Figure 1 is an overview of an installation produced according to the invention.
- Figure 2 is a schematic detail view of the cooling assembly or more precisely of controlling the temperature of the filaments before introduction into the drawing slot proper; .
- Figure 3 is a schematic view showing the general structure of a stretching slot. Way of realizing the invention
- the installation according to the invention therefore essentially consists of at least one extruder, designated by the general reference (1) supplying synthetic polymer such as polyamide,
- the die can consist of a perforated plate comprising 5000 holes, for example 0.5 mm in diameter,
- the length of this cooling zone is of the order of
- the air temperature in this zone will generally be between 15 and 60 ° C., the speed of the air passing through being between 0.5 m / s and 3 m / s.
- the actual stretching assembly (5) Downstream of this cooling zone, the actual stretching assembly (5) is arranged which is in the form of a closed enclosure comprising a slot (6) inside which is injected air at a pressure of 0.5 to 1.5 bar.
- such a stretching system can be designed in a similar manner to the teachings of FR 1,582,147 or GB 932,482 (FIG. 3) and which makes it possible to obtain the suction of the curtain of filaments and its entrainment by high speed air streams allowing to carry out a stretching.
- FIG. 3 where such a stretching assembly (5) is shown diagrammatically, this essentially consists of a stretching slot proper (10), the air coming from a collector (11) being introduced inside this chamber (10) through a distributor (12) and an acceleration chamber (13).
- Such a suction / stretching assembly is however preferably designed so that the width (F) of the slot (10) can be modified during operation of the installation, which allows on the one hand to adjust the speed d 'flow of air streams and, therefore, the fineness of the title that one wishes to obtain and on the other hand, facilitates the launching operation as will be seen in the following description.
- the width (F) of the slit will be between 3 mm and 10 mm, this spacing of the slit can be increased to 25 mm when of the launch phase.
- the bundle of filaments (3) is projected onto the receiving belt (7) not directly as is apparent from FR 2 064 087 or from US 4 064 605, but through an assembly (6) causing a deflection of the air jet leaving the slot (5) and a slowing down of this air jet, causing the opening of the curtain of filaments and the distribution of the latter over the receiving mat (7).
- Such an assembly can for example be in the form of a slot with divergent walls.
- the means allowing the electrostatic charge of the filaments can be integrated at the inlet of the divergent walls of the distributor element (6).
- a nonwoven web is made up of continuous filaments from polypropylene, in this case 38 MSR.
- the polymer is melted in an extradeuse with five melting zones and at the exit of the extradeuse, it is filtered on a filter composed of stainless steel mesh before being introduced into the die proper (2).
- the machine comprises two dies (1) arranged in series, each comprising 5000 holes of 0.5 mm in diameter per meter of width.
- the cooling zone (4) and the stretching zone (5) preferably consists of a plurality of elementary modules each having a width of 50 cm.
- (5) has, meanwhile, a continuous slot extending over the entire width of the installation and having the shape of a divergent whose width is 15 mm opposite the exit zone of the filaments from the slot (5) and 100 mm opposite the receiving belt (7).
- the distributor assembly (6) can optionally be associated with additional means also allowing the filaments to be electrostatically charged, thereby improving the bursting of the bundle and the distribution of the latter on the receiving belt (7).
- the line is started at low production with a polymer flow rate set at 0.2 g / min and per hole.
- a cooling zone (4) comprising three successive zones (4a, 4b, 4c) having a total length of approximately 1200 mm during which the bundle of extruded filaments (3) is subjected to a flow of through air coming from each of these zones, under the following conditions:
- the width (F) of the stretching slit (5) is adjusted to 25 mm, the pressure of the air injected into said slit being 0.3 bar.
- the stretched beam passes, at the outlet from the stretching slot (5), into the system (6) for opening and distributing said beam which is in the form of a divergence, having a width at the entrance of 20 mm and a opening at the base of the order of 100 mm.
- the polymer is collected on a conveyor belt (7) by means of a "leader" which is unwound on said belt and which prevents drops of molten polymer from clogging it.
- the temperature of the stretching air is controlled and remains constant throughout this period.
- the structure of the filament opening system arranged downstream of the drawing system and independent of the latter also promotes regular and homogeneous deposition of the filaments on the receiving surface (7).
- the production of filaments with very fine titles is accompanied by a high speed, of the order of 5000 m / min of the filaments at the outlet of the drawing slot.
- the device (6) used in the installation according to the invention allows a slowing down of the speed of said filaments as well as of the air flow leaving the drawing slot, favoring their distribution on the conveyor belt by the fact that it eliminates rebound phenomena likely to disturb a regular and homogeneous deposit.
- the veils obtained can weigh from 10 to 150 g / m 2 , are very regular, and can be used for various applications such as hygiene products (baby diapers), products for medical or industrial use.
