Definitions
- non-woven fabrics known as “wet” produced using a technology close to the manufacture of paper
- dry made of staple fibers, natural or chemical, obtained by carding, coating or any other material for textile preparation
- _ nonwovens known as “melted” made up of continuous chemical filaments and commonly designated under the generic name of “spunbond”.
- the present invention relates to an improvement made to the technology allowing such spunbond type nonwoven plies to be produced and more specifically relates to a process, an installation and a new type of product obtained by the use of these means, product having the appearance and the properties such as touch, mechanical characteristics, flexibility, close to a conventional textile, fabric in particular.
- the sheet After production, and in general continuously, the sheet is consolidated, for example by performing a calibration or calendering, preferably hot, so that the elementary filaments are linked to each other.
- the process according to the invention making it possible to obtain a nonwoven of the “spunbond” type having the appearance and the properties of a conventional textile, consists, continuously:
- _ producing a “spunbond” type sheet, the bundle of extruded and drawn continuous filaments being received on a movable conveyor belt in the form of an unbound sheet; _ to deliver, against at least one face of the “spunbond” sheet thus formed, a veil of staple fibers - natural and / or artificial and / or synthetic - obtained by carding or other conventional technique; _ compacting the complex thus formed by pressing; _ to transfer, always continuously, said complex onto a binding treatment line by means of water jets, acting against the surface or surfaces of the complex consisting of staple fibers, entraining said fibers in the thickness direction, fibers which bind like a splice between and around the continuous filaments while remaining visible on the surface; _ to carry out a drying treatment;
- compaction is carried out by pressing of the assembly constituted by the supe ⁇ osition of the layer or layers of staple fibers which cover or trap between them the "spunbond" tablecloth produced.
- Such compaction which can be carried out by any suitable means, such as in particular by means of a pressing roller, can in no case be assimilated to a calendering operation since it is carried out cold.
- a single veil of staple fibers can be associated with the veil with the “spunbond” type web, said veil of staple fibers being able to be delivered either upstream of the zone of formation of the “spunbond” veil and being brought on the conveyor belt on which are deposited the filaments coming from the “spunbond” installation, filaments which are therefore distributed on the surface of this veil, that is to say, delivered downstream of the zone of formation of the veil of continuous filaments.
- the “spunbond” type sheet is covered on its two faces by a veil of discontinuous fibers, produced one upstream of the zone of formation of the “spunbond” veil, the other downstream , the web of continuous filaments thus being trapped sandwiched between the two layers of staple fibers.
- the complex thus made up of three layers is, after compacting by pressing, transferred, always continuously, onto a binding treatment line by means of water jets, jets which act successively against the surfaces of said complexes entraining the staple fibers in the thickness direction, fibers which bond in the manner of a splice between and around the continuous filaments while remaining visible on the two outer faces.
- an additional “texturing” treatment (carried out for example in accordance with the teachings of patent EP-059 608), consisting in transferring the complex linked on a conveyor constituted by a coarse cloth and to subject the tablecloth to the action of water jets obtained by the intermediary of an assembly essentially comprising a rotary perforated drum, inside which is disposed a fuel injector in pressurized water, this assembly producing jets reorienting the fibers, a suction assembly for removing water being provided below the conveyor.
- the invention also relates to an installation allowing the continuous implementation of the above method.
- such an installation comprises, arranged in line:
- _ a formation assembly, on a conveyor belt, of a web of continuous spunbond type filaments; _ at least one card or other equivalent system making it possible to deliver against at least one face of the “spunbond” sheet produced a web of staple fibers;
- such an installation comprises, between the means of binding by water jets and the drying means, a set of texturing producing jets redirecting the fibers.
- the article obtained is characterized in that the continuous filaments which compose it are associated with discontinuous fibers, fibers which cover the sheet based on continuous filaments and penetrate inside this. the latter by binding around said filaments.
- Such a product retains all the mechanical characteristics of resistance of conventional spunbond plies, the cohesion of which is given by a calendering treatment, the product obtained also having the appearance and the properties such as feel and flexibility comparable to a conventional textile.
- the staple fibers which are associated with the spunbond layer can be of any type, natural or chemical, hydrophobic or hydrophilic, depending on the applications for which the product is intended, the length of said fibers being between 5 mm and 60 mm and their titer between 0.8 dtex and 6.6 dtex.
- the grammage of the veil (s) of staple fibers which are associated with the spunbond batt may vary depending on the applications, but will advantageously be between 10 g / m2 and 50 g / m2, a batt having a lower grammage at 10 g / m2 which does not allow correct binding of the spunbond ply, while a ply greater than 50 g / m2 reduces the economic advantage of the process.
- _ Figure 1 illustrates, seen from the side, an entire production line for implementing the method according to the invention
- _ Figure 2 is also a side view, showing in more detail how the binding operation is carried out by means of water jets and any additional texturing treatment.
- the invention therefore relates to a method and an installation which makes it possible to produce, continuously, a new type of “spunbond” plies made of continuous synthetic filaments, plies which not only retain the properties of mechanical resistance ( elongation, tensile strength, tear resistance ...), equivalent to conventional "spunbond” plies consolidated by hot calendering and which, moreover, have the appearance, feel and flexibility of a conventional textile such than a fabric.
- a “spunbond” type nonwoven sheet is produced according to the conventional technique which consists in extruding a molten organic polymer, through a die (2) pierced with holes so as to form a bundle or curtain of filaments (3).
- the “spunbond” sheet (S) in order to consolidate the “spunbond” sheet (S) thus formed and to give cohesion to this sheet and high mechanical characteristics of tensile and tear resistance while giving it an appearance, a feel and the flexibility of a conventional textile, the “spunbond” sheet (S) is received not directly on the surface of a conveyor belt (5) subjected to a suction source, but, on a veil (NI) of fibers discontinuous - natural and / or artificial and / or synthetic - produced immediately upstream of the “spunbond” installation (1).
- NI veil
- This veil (NI) is for example produced by means of a conventional assembly (6) consisting of a card possibly associated with a lapper spreader assembly, the veil (NI) produced being delivered to the conveyor belt (5) of the “spunbond” installation (1) by a supply assembly also consisting of a conveyor belt (7).
- the two textile layers (NI) and (S) supe ⁇ osées then pass, still being held on the conveyor belt (5), on a first assembly (8), constituted for example by two cylinders to ensure compaction.
- the three textile layers are delivered to the surface of the spunbond ply (S), a second web (N2) of staple fibers.
- elementary supe ⁇ oses (NI, S and N2) being compacted again by pressing between two cylinders (8).
- the compacted assembly is then brought to a treatment line, illustrated in more detail in FIG. 2, designated by the general reference (10) enabling said complex to be subjected to a binding treatment by means of jets of water, acting successively against the two surfaces of said complex.
- a treatment line illustrated in more detail in FIG. 2, designated by the general reference (10) enabling said complex to be subjected to a binding treatment by means of jets of water, acting successively against the two surfaces of said complex.
- such a treatment assembly (10) is constituted by a hydraulic binding unit of the “Jetlace 2000” type marketed by the Applicant and implementing the teachings of FR-A-
- Such a binding unit essentially consists of a conveyor (11) onto which the fibrous structure constituted by the three supe ⁇ osed layers (NI, S and N2) is transferred.
- the structure is compacted between the conveyor (11) and a first suction cylinder (12), preferably coated with a microperforated envelope, the holes of which are arranged randomly as described in French patent 2,734,285.
- this cylinder can be covered with a wire mesh.
- the complex sheet (N1 / S / N2) designated in the following description by the reference ( ⁇ )
- can receiving a first wetting treatment by means of a ramp (13), illustrated in dotted lines in FIG. 2, and which delivers a curtain of water which passes through the conveyor belt (11) as well as the supe ⁇ osed layers.
- the compacted complex supported by the suction drum (12), is then subjected to the action of water jets coming from an injector (14), the jets therefore acting against the surface formed by the fibrous web (NI) and entraining the fibers which constitute this veil inside the complex.
- the ramp or injector (14) arranged parallel to a generator of the cylinder (12), is a conventional ramp which makes it possible to create jets or needles of water having a diameter of 100 to 170 microns, the jets being spaced from each other with a value between 0.5 and 2.2 mm, the supply pressure itself between 50 and 150 bars depending on the grammage of the complex.
- the treated complex is brought to the surface of a second cylinder (15), identical to the previous suction cylinder, associated with one or two series of injectors (16,17) delivering jets of water which therefore act on the face of the sheet ( ⁇ ) formed by the web (N2).
- the ramps (16,17) create jets or needles of water having a diameter of 100 to 170 microns, said jets being spaced as before from each other between 0.5 and 2.4 mm, and the supply pressure being between 50 bars and 400 bars.
- the action of the injectors (16,17) therefore makes it possible to entrain the fibers of the NI veil in the thickness of the sheet ( ⁇ ), said fibers surrounding the continuous filaments and binding to the latter.
- the linked spun web designated by the reference (18) can be brought directly to the drying assembly (19) by passing over a conventional heating drum (26) before being received.
- a third hydraulic binding treatment can be carried out by means of a third suction drum (20) associated with a ramp of injectors (21), the jets of which act against the face which was constituted by the veil (NI).
- Such treatment consists, as more particularly of FIG. 2, of transferring the linked “spun” ply (18) onto an assembly produced for example in accordance with the teachings of patent EP 059
- such an assembly is constituted by a conveyor belt (22), of the "Fourdrinier” type, used in the paper industry.
- the linked spun (18) maintained on this canvas is subjected to the action of a series of water jets obtained by means of a ramp (23) projecting a curtain of water against the internal surface of a perforated rotary cylinder (24), these jets redirect the fibers.
- a suction assembly (25) for removing water is of course provided below the conveyor (22).
- This example uses the realization of a complex in which the veil the "spunbond" sheet is trapped between two veils of staple fibers.
- a veil of fibers (NI) weighing 30 g / m 2 and composed of 100% viscose fibers of 1.7 dtex and 38 mm in length is produced.
- This veil is produced at a speed of 100 m / minute.
- the web (NI) is transferred to the receiving mat (5) of the installation (1) for producing a ply (S) of the "spunbond" type.
- the “spunbond” sheet produced is obtained from polypropylene and is distributed over the web (NI) so as to form a sheet made up of filaments having a titer of 1.7 dtex, weighing 40 g / m 2 .
- the two superposed layers (NI) and (S) are compressed by means of a pressing cylinder (8) and a second veil of fibers (N2) reproduced in a similar manner to the veil (NI), weighing 30 g / m 2 , is delivered to the surface of the tablecloth
- the complex formed is brought to a treatment line comprising a hydraulic binding unit (10) of the “Jetlace 2000” type, sold by the Applicant.
- Such an installation essentially comprises a conveyor belt (11), and three sets of treatment by jets comprising suction cylinders
- the ramps (14,16,17,21) all produce 1666 jets per meter and are adjusted as follows.
- a texturing assembly constituted by a conveyor belt (22) made of a polyester fabric, associated with a texturing assembly proper comprising a rotary perforated drum (24) with inside which is arranged an injector (23) supplied with water at 150 bars.
- This injector (23) produces water jets of 130 ⁇ m in diameter which redirect the fibers.
- the water coming from the injector (23) is recovered by means of the suction assembly (25) arranged below the conveyor (22).
- a sheet according to the invention is obtained at the outlet of the installation which, after drying on a heating drum, weighs 95 g / m 2 .
- This example illustrates the implementation of the method according to the invention for the production of a structure composed of a “spunbond” type sheet associated with a single fibrous sheet which, in this embodiment, is formed upstream of the spunbond formation area.
- a veil of fibers (NI) weighing 20 g / m2 is produced, composed of 100% viscose fibers of 1.7 dtex and 38 mm in length.
- This veil is produced at a speed of 150 m / min.
- the web (NI) is transferred to the receiving mat (5) of the spunbond unit.
- a spunbond sheet (S) made of polypropylene filaments is deposited on the web (NI).
- This 25 g / m2 spunbond tablecloth is made of 2 dtex filaments.
- the two superposed layers (NI) and (S) are compressed by means of a pressure roller (8) thus forming a complex of 45 g / m2 which is transferred continuously onto a hydraulic binding unit (10) of the “Jetlace” type. 2000 ”marketed by the Applicant.
- This installation comprises a conveyor belt (11) and two sets of treatment by water jets consisting of suction cylinders (12) and (15) followed by a final conveyor (22) on which is placed a patterning / texturing device.
- the two cylinders (12) and (15) are covered with a microperforated envelope, the holes of which are arranged randomly as described in French patent 2,634,285. These cylinders are associated with injector ramps (14) (16) (17).
- the injectors produce all 1,666 water jets of 120 microns per meter and the water pressure in these injectors is 60, 80 and 110 bars respectively.
- the bonded complex is textured on the preceding cylinders by a perforated drum (23) as described in the previous example, the injector of which is supplied at a water pressure of 80 bars.
- the final product of 45 g / m2 has excellent mechanical characteristics, superior to those of a spunlace veil made of fibers of the same kind.
- the aspect and the flexibility of the veil are also remarkable, very superior to those of a spunbond in polypropylene or polyester of equivalent grammage bound by calendering.
