Definitions
- the present invention relates to an improvement made to installations allowing the manufacture of a nonwoven textile web, commonly known by the generic name of "spunbond", and which is formed by continuous synthetic filaments.
- It relates more particularly to an improvement made to the means allowing the distribution of the extruded filaments, after drawing, on a mobile conveyor belt on which they are distributed randomly so as to form a regular sheet, of weight and thickness adjustable according to applications.
- the sheet is consolidated, for example by performing a calibration or calendering, preferably hot, so that the elementary filaments are linked to each other.
- 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, assembly which in the rest of the description will be designated by the expression "drawing slot” and;
- _ a means allowing, at the outlet of said stretching slot, to deflect and slow down the air flow and to distribute the filaments randomly on a receiving mat.
- the filaments appear at the outlet from the drawing slot in the form of a bundle of filaments grouped in the median plane of said slot.
- These filaments are ejected at very high speed from said stretching slot, speed which can reach 3000 m / min or more depending on the state.
- the veil consists of relatively coarse filaments, that is to say of a titer greater than or equal to 2.2 dtex per filament, filaments which are generally produced with velocities at the output of stretching slot less than 3000 m / min.
- the end of the stretching slot on which the electrostatic device is fixed is located at a relatively large distance from the receiving belt, of the order 500 mm or more, so that the friction forces of the filaments in the air slow down their speed, which limits rebound phenomena and thus improves the formation of the web.
- Such a device satisfactory in theory, however has limited effectiveness, because it is mainly the fibers located on each side of the bundle which are thus "spaced", those grouped in the center of said bundle being extremely difficult to separate from each other.
- the invention therefore relates to a device making it possible to ensure the opening and the distribution of a bundle of filaments during the production of a nonwoven textile web, according to the technique which consists:
- _ to extrude a molten organic polymer through a die pierced with holes, so as to form a bundle or curtain of filaments; _ then, to orient the extruded filaments by drawing by means of one or more fluid jets devices; _ and finally, to receive the bundle of filaments in the form of a sheet on a mobile conveyor belt below which a suction source is arranged.
- the device for opening and distributing the bundle of filaments consists of an assembly arranged downstream from the outlet of the drawing assembly and dissociated from the latter, this assembly comprising, disposed close to the outlet from the stretching slot, a diffuser comprising a converging-shaped inlet zone extending over the entire width of the installation with regard to the outlet from the stretching slot for producing the web, extended by a divergent, said assembly being associated with a ramp electrostatically charging the filaments before reception on the receiving belt.
- the divergent zone of the diffuser has two walls and two lateral slots situated at the top of said diffuser, on each side of the latter and allowing either a call for air from the outside by the Venturi effect, or possibly a air injection, at a pressure below one bar and advantageously between 0.4 and 0.8 bar, causing air to flow against the walls of said diffuser.
- the above diffuser allows precise adjustment of the width of the fiber bundle as well as the impact speed of the filaments on the receiving mat, the electrostatic charge assembly possibly being located downstream of the diffuser assembly, but being of preferably integrated inside the latter, which makes it possible to accentuate the opening of the bundle of filaments.
- the diffuser has a convergent entry zone connected to the two walls of the diverging zone by a rectilinear slot, the ramp electrostatically charging the filaments being mounted at the rectilinear slot immediately upstream of the diverging zone;
- the distance of the diffuser from the receiving belt is adjustable, in order to minimize the influence of external air currents on the fiber bundle
- the pressure of the air flowing in the diffuser against the walls of the latter and the adjustment of the voltage applied in the electrostatic ramp makes it possible to very precisely adapt the conditions of the formation of the veil as a function of the speed of the filaments at the outlet of the stretching slot, which makes such a device particularly suitable for forming a veil consisting of low denier filaments, as well as for production installations working at high speed;
- FIG. 1 is an overall view of an installation making it possible to produce a “spunbond” type nonwoven web;
- Figure 2 is a detail view schematically showing the structure and operation of an assembly allowing the opening of the bundle of filaments formed and its deposit on the receiving belt;
- FIG. 3 illustrates an alternative embodiment according to the invention in which the electrostatic charge of the filaments is obtained by means of a ramp integrated inside the diffuser, the flow of air inside the latter against the walls can be achieved either by natural call of outside air, or by a low pressure injection system less than a bar.
- the device according to the invention is therefore intended to be used on a production line of a nonwoven textile web constituted by continuous synthetic filaments.
- such a production line therefore essentially consists of at least one extruder, designated by the general reference (1) supplying synthetic polymer such as polyamide, polyethylene, polyester ..., a die (2) allowing the formation of a curtain of filaments (3).
- the die consists of a plate each comprising a multitude of holes, for example the number of
- a cooling assembly (4) is arranged allowing the temperature of the filaments to be adjusted as a function of the polymers and composed for example of a plurality of successive zones (4a, 4b, 4c) making it possible to subject the curtain of filaments (3) to through air flows whose speed and temperature can be adjusted.
- the length of this cooling zone is of the order of
- an actual stretching assembly (5) is arranged which is in the form of a closed enclosure comprising a slot (F) inside which air is injected under pressure, for example of the order of 0.5 bar.
- Such a stretching system makes it possible to obtain the suction of the curtain of filaments and its entrainment by air streams at high speed making it possible to ensure the stretching.
- the bundle of filaments (3) is projected onto the receiving belt (7) by means of an assembly (6), which assembly is the subject of the invention and two embodiments of which emerge from FIGS. 2 and
- such an assembly comprises, near the outlet of the drawing slot (F) of the assembly (5), on the one hand, a diffuser, designated by the general reference (10) consisting essentially of a divergent which extends over the entire width of the production of the sheet and, on the other hand, downstream of this opening assembly, a ramp (11) for electrostatically charging the filaments at the outlet of the assembly (10) causing an opening at the heart of said bundle of filaments before depositing them on the receiving belt (7).
- a diffuser designated by the general reference (10) consisting essentially of a divergent which extends over the entire width of the production of the sheet and, on the other hand, downstream of this opening assembly, a ramp (11) for electrostatically charging the filaments at the outlet of the assembly (10) causing an opening at the heart of said bundle of filaments before depositing them on the receiving belt (7).
- the diffuser assembly (10) essentially consists of a chamber (12) comprising an internal slot (13) in the form of a convergent / divergent extending over the entire width of the installation opposite the outlet of the stretching slot (F) of the assembly (5).
- this slot (13) open, near the lower part of the divergent zone, two symmetrical slots (14) arranged laterally.
- These symmetrical slots (14) can either be connected to a source of compressed air injected under a pressure of less than 1 bar and advantageously of the order of 0.4 bar, or be simply open to the open air.
- the divergent zone is, in this embodiment, extended by two equally divergent walls (15).
- a conventional ramp (11) for electrostatically charging the filaments thus making it possible to accentuate the opening of the beam.
- a ramp (11) is a conventional ramp, for example of the type described in US-A-3,967,118.
- FIG. 3 illustrates a second embodiment of an assembly for opening and distributing a bundle of filaments in the form of a sheet produced in accordance with the invention.
- the device for opening and distributing the bundle of filaments (6) is, as previously, dissociated from the set of drawing (5).
- this embodiment also comprises an inlet zone (13) in the form of a convergent extending opposite the outlet from the drawing slot (F).
- This converging-shaped entry zone (13) is connected to the two walls (15) of the divergent zone by a rectilinear slot (20).
- the ramp (11) for electrostatically charging the filaments is, in this embodiment, integrated inside the diffuser, at the end of the straight slot (20) immediately upstream of the diverging zone (15).
- a call for air from the outside by Venturi effect is made through the two adjoining lateral slots formed by the underside of the drawing assembly (5) and the top face of the opening and distribution (6).
- an injection of air, under low pressure, less than 1 bar, could be carried out at the two lateral slots formed between the drawing assembly (5) and the opening and distribution assembly (6).
