Definitions
- the present invention relates to an improved installation allowing the manufacture of a nonwoven textile tablecloth, commonly known as generic "spunbond" and which is formed by synthetic filaments continuous
- the sheet is consolidated, for example by carrying out a sizing or calendering, preferably hot, so that the filaments are linked to each other.
- consolidation treatments can also be performed, such as that for example a needling treatment (conventional or by jets of fluid), and / or the deposition on the surface or inside the sheet of a binding material.
- GB-A-932 482 in which the filaments, after extrusion, travel in the open air leaving the die for a sufficient distance to allow at least superficial solidification of said extruded filaments before introduce them inside a suction and stretching nozzle creating the high speed annular airflow.
- these receive a electrostatic charge which can be obtained by an electrostatic generator causing a Corona-like effect located upstream or downstream of the nozzle suction.
- US-A-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, in subjecting the bundle of filaments to a transverse air flow.
- stretching of the filaments also involves being able to brake the air streams coming out of the slit drawing to obtain a regular deposit of the filaments on the receiving conveyor and the production of a good quality veil.
- the installation according to the invention is of the type defined in claim 1.
- the air temperature inside each cooling zone is generally included in a range which can range from 5 ° C to 60 ° C.
- the installation according to the invention is 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 sector can be constituted a perforated plate comprising 5000 holes, for example 0.5 mm in diameter, per meter of width. These holes are distributed over a plurality of parallel rows, for example on eighteen rows and this, on a die outlet width of 140 mm.
- the cooling assembly (4) allowing the regulation of the temperature of the filaments as a function of the polymer and which, according to the invention, consists of three successive zones (4a, 4b, 4c) allowing the filament curtain (3) to be subjected to through air flows, speed and temperature can be adjusted.
- this cooling zone is of the order of 1200 mm and the temperature and speed of each of the zones decreasing by the first zone (4a) to the third zone (4c).
- the air temperature in this area will generally be between 15 and 60 ° C, the speed of the through air being between 0.5 m / s and 3 m / s.
- the stretching assembly Downstream of this cooling zone, the stretching assembly is arranged. proper (5) which is in the form of a closed enclosure comprising a slot (6) inside which air is injected at a pressure of 0.5 to 1.5 bar.
- such a stretching system can be designed in a similar to the teachings of FR 1,582,147 or GB 932,482 ( Figure 3) and which allows to obtain the suction of the curtain of filaments and its training by high speed air streams for stretching.
- this consists essentially of a proper stretching slot (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 to that the width (F) of the slot (10) can be changed during operation of the installation, which allows on the one hand to regulate the flow speed of the veins of air and, consequently, the delicacy of the title which one wishes to obtain and on the other hand, facilitates the launch operation as will be seen in the following description.
- the width (F) of the slot will be between 3 mm and 10 mm, this gap spacing can be increased to 25 mm during the launch phase.
- the bundle of filaments (3) is projected on the receiving belt (7) not directly as is apparent from FR 2 064 087 or US 4,064,605, but through a set (6) causing a deviation of the air jet leaving the slot (5) and a slowing down of this air jet, causing opening the curtain of filaments and distributing them on the carpet receiver (7).
- Such an assembly can for example be in the form of a slot divergent walls.
- the means allowing the electrostatic charge of the filaments can be integrated at the entrance of the divergent walls of the element distributor (6).
- a nonwoven web consisting of continuous filaments from polypropylene, in the present case of 38 MSR.
- the polymer is melted in an extruder with five melting zones and at the exit of the extruder, it is filtered on a filter composed of stainless steel mesh before being introduced into the chain itself (2).
- the machine has two dies (1) arranged in series, each comprising 5000 holes of 0.5mm in diameter per meter of width.
- the cooling zone (4) and the stretching zone (5) preferably consists of a plurality of modules elementary each having a width of 50 cm.
- the distributor element (6) arranged at the outlet of the stretching zone (5) has, in turn, a continuous slot extending over the entire width of the installation and having the shape of a divergent whose width is 15 mm in looking at the exit area of the filaments from the slot (5) and 100 mm opposite the receiving mat (7).
- the distributor assembly (6) can possibly be associated with means also allowing electrostatic charging of the filaments thus improving the bursting of the beam and their distribution on the carpet receiver (7).
- the line is started at low production with a flow of polymer set at 0.2 g / min and per hole.
- the width (F) of the stretching slot (5) is adjusted to 25 mm, the pressure of the air injected into said slot being 0.3 bar.
- the stretched beam passes, at the outlet of the stretching slot (5), into the system (6) of opening and of distribution of said beam which is in the form of a divergent, having a width at the entrance of 20 mm and an 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.
- both the air pressure and the width of the stretching slot optimizes the conditions drawing, which, of course, results in obtaining a high production associated with the production of very fine filaments.
- the structure of the filament opening system located downstream of the stretching system and independent of it also promotes regular deposition and homogeneous filaments on the receiving surface (7).
- the production of filaments with very fine titles is accompanied of a high speed, of the order of 5000 m / min of the filaments leaving the slot stretching.
- 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 stretching slot, favoring their distribution on the conveyor belt by the fact that it eliminates rebound phenomena likely to disrupt regular deposition and homogeneous.
- 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.
