Description

PROCEDE POUR LA REALISATION D'UN MATERIAU NON TTSSEPROCESS FOR THE PRODUCTION OF A NON-TTSSE MATERIAL
COMPLEXE ET NOUVEAU TYPE DE MATERIAU AINSI OBTENU.COMPLEX AND NEW TYPE OF MATERIAL SO OBTAINED.
Domaine Technique Depuis des décennies, il a été proposé de remplacer des nappes textiles traditionnelles (tissu, tricot) par des structures dites « non-tissées ».Technical Field For decades, it has been proposed to replace traditional textile tablecloths (fabric, knitting) with so-called "non-woven" structures.
D'une manière générale, de telles structures non-tissées peuvent être classées en trois grandes catégories, résultant de leur processus même de fabrication, à savoir les non-tissés dits « par voie sèche » formés par cardage et/ou voie aéraulique, cette dernière technique étant couramment désignées par l'expression « technique airlaid », les non-tissés obtenus par « voie fondue », technique couramment désignée par l'expression « spunbond », et la technique dite « par voie humide », dérivée des techniques papetières.In general, such nonwoven structures can be classified into three main categories, resulting from their very manufacturing process, namely the so-called “dry” nonwovens formed by carding and / or aeraulic route, this last technique being commonly designated by the expression "airlaid technique", the nonwovens obtained by "melted", technique commonly designated by the expression "spunbond", and the technique known as "wet", derived from paper techniques .
Par ailleurs, il est connu depuis fort longtemps, qu'il est possible d'adapter les propriétés finales du produit obtenu en réalisant des mélanges de matières, par exemple en associant entre eux plusieurs voiles constitués de fibres de nature différente, par exemple des fibres naturelles, artificielles ou synthétiques.Furthermore, it has been known for a very long time that it is possible to adapt the final properties of the product obtained by making mixtures of materials, for example by combining together several webs made up of fibers of different nature, for example fibers natural, artificial or synthetic.
L'invention vise un nouveau procédé permettant de réaliser un tel type d'article non-tissé constitué d'un mélange de fibres de nature différente et qui, dans la suite de la description, sera désigné par l'expression « non-tissé mixte » ou « non-tissé composite ».The invention relates to a new process making it possible to produce such a type of nonwoven article made up of a mixture of fibers of different nature and which, in the following description, will be designated by the expression “mixed nonwoven "Or" composite nonwoven ".
Techniques antérieuresPrevious techniques
De très nombreuses propositions ont été faites à ce jour pour réaliser des non tissés mixtes ou composites en associant entre eux des voiles de fibres artificielles ou synthétiques et un voile de fibres cellulosiques. L'association des différents constituants entre eux peut être réalisée de différentes manières, par exemple au moyen de liants, aiguilletage mécanique ou enchevêtrement hydraulique, cette dernière technique, connue depuis fort longtemps, étant décrite notamment dans le brevet US 3 508 308. Ce document décrit notamment la réalisation de nappes mixtes réalisées par la technique « airlaid » par mélange intime de fibres, par exemple un mélange de fibres synthétiques (polyester ou acrylique) et de fibres de rayonne (voir exemples 10 et 11). Il décrit également (voir exemples 12 et 13), la réalisation de complexes comportant une couche centrale constituée de filaments continus et de deux couches extérieures à base de fibres, polyester notamment, distribuées par voie aéraulique, les différentes couches étant liées entre elles par l'action de jets de fluide.Very many proposals have been made to date for making mixed or composite nonwovens by associating between them veils of artificial or synthetic fibers and a veil of cellulosic fibers. The association of the various constituents with one another can be carried out in different ways, for example by means of binders, mechanical needling or hydraulic entanglement, the latter technique, known for a very long time, being described in particular in US Pat. No. 3,508,308. This document describes in particular the production of mixed plies produced by the "airlaid" technique by intimate mixing of fibers, for example a mixture of synthetic fibers (polyester or acrylic) and rayon fibers (see examples 10 and 11). It also describes (see examples 12 and 13), the production of complexes comprising a central layer consisting of continuous filaments and two outer layers based on fibers, in particular polyester, distributed by air, the different layers being linked together by the action of fluid jets.
Il a également été proposé, comme cela ressort de l'EP 423 619, de réaliser des tissus absorbants par association, toujours au moyen de jets d'eau, d'une nappe constituée de filaments continus et d'une nappe constituée d'un mélange de fibres cellulosiques, fibres de bois notamment.It has also been proposed, as is apparent from EP 423 619, to produce absorbent fabrics by association, still by means of water jets, of a sheet made up of continuous filaments and of a sheet made up of a mixture of cellulose fibers, wood fibers in particular.
Enfin, il est connu de réaliser des non-tissés en prenant en sandwich une nappe de fibres entre deux voiles de filaments continus déjà consolidés par calandrage à chaud, la liaison finale des différentes couches étant également assurée par l'action de jets d'eau.Finally, it is known to produce nonwovens by sandwiching a sheet of fibers between two webs of continuous filaments already consolidated by hot calendering, the final connection of the different layers also being ensured by the action of water jets. .
Cette dernière technique de mise en œuvre relativement simple présente de nombreux inconvénients majeurs, à savoir : le fait que les voiles de filaments continus (spunbond) soient déjà consolidés par un traitement thermique de calandrage interdit un mélange intime de ces filaments avec les fibres de bois du voile déposé par voie aéraulique, ce qui diminue les capacités d'absorption du complexe et également conduit à l'obtention d'un produit rêche manquant de souplesse ; par ailleurs, il est nécessaire, pour assurer une cohésion satisfaisante entre les couches et éviter le délaminage du complexe, d'utiliser lors de la phase de consolidation par jets d'eau des vitesses de fluide très importante, car les points de calandrage des voiles spunbond empêchent toute mobilité des filaments synthétiques ; ces vitesses élevées des jets d'eau engendrent un surcoût de consommation d'énergie ainsi qu'une perte accrue de fibres cellulosiques ; les points de liaison entre les filaments obtenus par calandrage peuvent représenter jusqu'à 20 à 25 % de la surface des voiles à base de filaments continus et constituent donc autant d'obstacles au passage des jets d'eau ;This latter relatively simple implementation technique has many major drawbacks, namely: the fact that the webs of continuous filaments (spunbond) are already consolidated by a calendering heat treatment prohibits intimate mixing of these filaments with the wood fibers veil deposited by air, which reduces the absorption capacity of the complex and also leads to the production of a rough product lacking flexibility; moreover, it is necessary, to ensure satisfactory cohesion between the layers and to avoid delamination of the complex, to use, during the phase of consolidation by water jets, very high fluid velocities, because the calendering points of the sails spunbond prevent any mobility of the synthetic filaments; these high speeds of the water jets generate an additional cost of energy consumption as well as an increased loss of cellulosic fibers; the connection points between the filaments obtained by calendering can represent up to 20 to 25% of the surface of the sails based on continuous filaments and therefore constitute as many obstacles to the passage of water jets;
^ enfin, le fait que les filaments continus des voiles ne soient pas mobiles confère une rigidité importante au matériau qui perd ses propriétés textiles et ressemble davantage à un papier qu'à un véritable textile. Exposé de l'invention^ finally, the fact that the continuous filaments of the sails are not mobile gives significant rigidity to the material which loses its textile properties and looks more like paper than real textile. Statement of the invention
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, un procédé perfectionné qui permet de réaliser en continu des non-tissés mixtes parfaitement liés, présentant des caractéristiques mécaniques élevées tout en conservant l'aspect, le toucher et la souplesse d'un textile conventionnel, tel qu'un tissu.However, we have found, and this is the subject of the present invention, an improved process which makes it possible to continuously produce perfectly bonded mixed nonwovens, having high mechanical characteristics while retaining the appearance, feel and flexibility of a conventional textile, such as a fabric.
La résolution d'un tel problème est obtenue par la combinaison, d'une manière bien précise, de techniques antérieures mises en œuvre en continu et dans les conditions bien précises, à savoir :The resolution of such a problem is obtained by the combination, in a very precise manner, of prior techniques implemented continuously and under very precise conditions, namely:
_ les techniques de réalisation de nappes non-tissées réalisées à partir de fibres courtes dont la répartition est obtenue par voie aéraulique (technique airlaid) ;_ the techniques for producing nonwoven sheets made from short fibers, the distribution of which is obtained by air flow (airlaid technique);
_ les techniques de réalisation de nappes obtenues par filature directe (spunbond) et,_ the techniques for producing plies obtained by direct spinning (spunbond) and,
_ la consolidation du complexe formé par l'action de jets d'eau._ the consolidation of the complex formed by the action of water jets.
D'une manière générale, le procédé conforme à l'invention consiste à réaliser en continu un complexe dans lequel on interpose en sandwich entre deux voiles de filaments continus, un voile fibreux à base de fibres cellulosiques, procédé qui consiste : à réaliser un premier voile de filaments continus, le faisceau de filaments continus extrudés et étirés étant réceptionné sur un tapis transporteur mobile sous la forme d'une nappe non liée ; à déposer sur ce voile, par voie aéraulique, un second voile de fibres cellulosiques ; à déposer sur le voile fibreux un deuxième voile de filaments continus non liés ; à transférer le complexe formé sur une installation de liage par jets d'eau et à consolider l'ensemble par enchevêtrement hydraulique et ;In general, the method according to the invention consists in continuously producing a complex in which a sandwich is interposed between two veils of continuous filaments, a fibrous veil based on cellulosic fibers, method which consists in: producing a first web of continuous filaments, the bundle of extruded and drawn continuous filaments being received on a movable conveyor belt in the form of an unbound web; to deposit on this veil, by air, a second veil of cellulosic fibers; depositing on the fibrous web a second web of unbound continuous filaments; transferring the complex formed to a binding system by water jets and consolidating the assembly by hydraulic entanglement and;
* à sécher le non-tissé mixte produit puis à le réceptionner, par exemple sous la forme d'un enroulement.* drying the mixed nonwoven product and then receiving it, for example in the form of a roll.
Selon une forme de réalisation préférentielle de mise en œuvre du procédé conforme à l'invention, les fibres cellulosiques entrant dans la réalisation du complexe sont des fibres de bois et leur dépôt est réalisé par nappage pneumatique. Par ailleurs, s'il peut être envisagé de ne réaliser qu'un seul traitement de liage par jet d'eau, le complexe formé est de préférence soumis à deux traitements successifs agissant contre les deux faces opposées du complexe.According to a preferred embodiment of implementation of the method according to the invention, the cellulosic fibers used in the production of the complex are wood fibers and their deposition is carried out by pneumatic coating. Furthermore, if it can be envisaged to carry out only one binding treatment by water jet, the complex formed is preferably subjected to two successive treatments acting against the two opposite faces of the complex.
L'invention concerne également un nouveau type de produit non-tissé obtenu par la mise en œuvre de ce procédé.The invention also relates to a new type of nonwoven product obtained by the implementation of this method.
Un tel non-tissé mixte, qui est donc constitué d'un mélange de fibres de nature différente, se caractérise en ce qu'il se compose d'une couche de fibres naturelles, bois notamment, emprisonnée entre deux nappes non tissées constituées de filaments, extrudés et étirés, à base de matière synthétique, la cohésion des différentes couches étant obtenue par enchevêtrement grâce à l'action de jets d'eau.Such a mixed nonwoven, which therefore consists of a mixture of fibers of different nature, is characterized in that it consists of a layer of natural fibers, wood in particular, trapped between two nonwoven sheets made of filaments , extruded and drawn, based on synthetic material, the cohesion of the different layers being obtained by entanglement thanks to the action of water jets.

Manière de réaliser l'inventionWay of realizing the invention
Sur une ligne de production, telle qu'illustrée à la figure 1, on réalise, en continu, un non-tissé composite.On a production line, as illustrated in FIG. 1, a composite nonwoven is produced continuously.
Pour ce faire, on réalise, au moyen d'une unité de production, désignée par la référence générale (1), par fusion, filage et étirage, un premier voile (2) de filaments continus, filaments qui sont déposés et répartis sur un tapis transporteur mobile (3). Eventuellement, immédiatement après formation, ce premier voile (2) peut être soumis à un compactage au moyen d'un cylindre presseur ou par action de jets provenant d'une rampe d'injecteurs hydrauliques.To do this, a first web (2) of continuous filaments is produced by means of a production unit, designated by the general reference (1), by fusion, spinning and drawing. These filaments are deposited and distributed over a mobile conveyor belt (3). Optionally, immediately after formation, this first web (2) can be subjected to compaction by means of a pressing cylinder or by the action of jets coming from a ramp of hydraulic injectors.
Les filaments continus de ce premier voile (2) peuvent être à base d'un polymère constitué de polypropylène, de polyester ou d'autres matières synthétiques tel que polyéthylène, polyamide, cette liste n'étant pas limitative. Les filaments continus peuvent éventuellement être constitués de filaments dits « bicomponent », tels que ceux obtenus par coextrusion de polypropylène et de polyéthylène.The continuous filaments of this first veil (2) can be based on a polymer consisting of polypropylene, polyester or other synthetic materials such as polyethylene, polyamide, this list not being limiting. The continuous filaments can optionally consist of so-called “bicomponent” filaments, such as those obtained by coextrusion of polypropylene and polyethylene.
Le voile de filaments (2) continus non liés, est ensuite transféré sous une unité, désignée par la référence générale (4), qui, par voie aéraulique, permet de déposer à la surface de la première nappe (2) des fibres discontinues (4), d'une autre nature, et plus particulièrement des fibres cellulosiques, bois notamment.The web of unbound continuous filaments (2) is then transferred under a unit, designated by the general reference (4), which, by air flow, makes it possible to deposit on the surface of the first ply (2) of staple fibers ( 4), of another nature, and more particularly of cellulose fibers, wood in particular.
Les fibres cellulosiques sont déposées à la surface du premier voile (2) par l'intermédiaire d'un courant d'air. De préférence, le voile de filaments (2) est maintenu sur le tapis transporteur (3) au moyen d'une aspiration (5). Par suite, sous l'effet de l'aspiration, lesdites fibres (4) sont déposées préférentiellement entre les filaments non liés du voile (2), permettant ainsi une excellente intégration des deux constituants.The cellulosic fibers are deposited on the surface of the first web (2) by means of a stream of air. Preferably, the veil of filaments (2) is held on the conveyor belt (3) by means of a suction (5). As a result, under the effect of the suction, said fibers (4) are preferably deposited between the unbound filaments of the web (2), thus allowing excellent integration of the two constituents.
Le complexe (2,4) qui est toujours maintenu supporté par le tapis transporteur (3), est ensuite amené en dessous d'une seconde zone de formation (6) d'un second voile de filaments continus (7), également synthétiques, de même nature ou de nature différente que ceux du premier voile (2).The complex (2,4) which is still maintained supported by the conveyor belt (3), is then brought below a second formation zone (6) of a second web of continuous filaments (7), also synthetic, of the same or different nature as those of the first veil (2).
Un rouleau presseur (8) est de préférence disposé après cette zone de dépôt du voile (7), et permet d'assurer un compactage de l'ensemble en vue de son transfert sur l'installation d'hydroliage, désignée par la référence générale (9), qui suit la ligne de production.A pressure roller (8) is preferably disposed after this zone for depositing the web (7), and makes it possible to ensure compaction of the assembly with a view to its transfer to the hydroliage installation, designated by the general reference. (9), which follows the production line.
Eventuellement, cette opération de compactage pourrait être réalisée au moyen d'une rampe d'injecteurs hydrauliques. Le complexe est ensuite introduit dans la zone d'hydroliage (9) sur un convoyeur (10) sur lequel sont effectuées successivement les opérations de compactage et prémouillage de l'ensemble par l'intermédiaire d'un convoyeur supérieur (11) tangent au convoyeur inférieur (10), et à l'intérieur duquel est disposé un injecteur hydraulique (12).Optionally, this compacting operation could be carried out by means of a ramp of hydraulic injectors. The complex is then introduced into the hydroliage zone (9) on a conveyor (10) on which the operations of compacting and pre-wetting of the assembly are successively carried out by means of an upper conveyor (11) tangent to the conveyor lower (10), and inside which is disposed a hydraulic injector (12).
Après compactage et prémouillage, le complexe est soumis à l'action d'une succession de jets d'eau (13) délivrés par plusieurs injecteurs hydrauliques disposés en série.After compacting and pre-wetting, the complex is subjected to the action of a succession of water jets (13) delivered by several hydraulic injectors arranged in series.
Ces jets d'eau (13) consolident l'ensemble constitué par les différentes couches du complexe et confèrent une bonne résistance à l'abrasion de la couche supérieure.These water jets (13) consolidate the assembly formed by the various layers of the complex and confer good resistance to abrasion of the upper layer.
La structure ainsi traitée est ensuite transférée, par retournement, sur un cylindre (14), ou sur un autre convoyeur, associé à plusieurs injecteurs (15) qui délivrent également des jets d'eau sur l'autre face du complexe, renforçant ainsi la consolidation de l'ensemble des couches, tout en conférant une bonne résistance à l'abrasion de la couche située en regard des jets.The structure thus treated is then transferred, by inversion, to a cylinder (14), or to another conveyor, associated with several injectors (15) which also deliver water jets on the other face of the complex, thus strengthening the consolidation of all of the layers, while providing good abrasion resistance of the layer facing the jets.
Le complexe ainsi obtenu est ensuite transféré sur un convoyeur d'exprimage (16) sur lequel il est exprimé à l'aide d'une caisse aspirante reliée à un générateur de vide.The complex thus obtained is then transferred to an expressing conveyor (16) on which it is expressed using a suction box connected to a vacuum generator.
II est ensuite séché au moyen d'un cylindre (17) à air traversant puis réceptionné de manière conventionnelle, par exemple sous la forme d'un enroulement (18).It is then dried by means of a through-air cylinder (17) and then received in a conventional manner, for example in the form of a winding (18).
Exemple On réalise un produit conforme à l'invention de la manière suivante.Example A product according to the invention is produced in the following manner.
Un voile de filaments continu (2), pesant 15 g/m2 est produit sur une installation commercialisée par le Demandeur sous la dénomination « spunjet », qui permet de réaliser une nappe non-tissée par extrusion, étirage et répartition de filaments continus. Dans cet exemple de réalisation, comme polymère, on extrade du polypropylène tel que celui commercialisé par la Société AMOCO sous la référence 100 ZA 35.A continuous veil of filaments (2), weighing 15 g / m 2 is produced on an installation marketed by the Applicant under the name "spunjet", which allows a nonwoven web to be produced by extrusion, drawing and distribution of continuous filaments. In this exemplary embodiment, polypropylene such as that sold by the company AMOCO under the reference 100 ZA 35 is extracted as a polymer.
Le voile formé est constitué de 7000 filaments par mètre de largeur et est produit à une vitesse de 250 mètres par minute. Le diamètre des filaments après étirage est d'environ 15 microns.The veil formed consists of 7000 filaments per meter of width and is produced at a speed of 250 meters per minute. The diameter of the filaments after drawing is approximately 15 microns.
Une aspiration située en regard de la fente d'étirage (20) permet de contrôler précisément le dépôt du filament et sa régularité sur le tapis transporteur (3).A suction located opposite the stretching slot (20) makes it possible to precisely control the deposition of the filament and its regularity on the conveyor belt (3).
Au dessus du même convoyeur (3), est disposé un ensemble (4) permettant de distribuer par voie aéraulique des fibres discontinues sur la nappe (2) préalablement formée.Above the same conveyor (3), is arranged an assembly (4) allowing aeraulic distribution of staple fibers on the sheet (2) previously formed.
Un tel ensemble de distribution de fibres peut être constitué par une installation conventionnelle telle que celle commercialisée par la Société M & J.Such a fiber distribution assembly can be constituted by a conventional installation such as that sold by the Company M & J.
Dans l'exemple concret, on dépose sur le voile de filaments continus (2) 35 g/m2 de fibres cellulosiques, et plus particulièrement de fibres de bois, commercialisées par la Société KORSNAES, ces fibres de bois, d'une longueur de l'ordre de 3 mm, étant couramment désignées par l'expression « pâte fluff ».In the concrete example, 35 g / m 2 of cellulose fibers, and more particularly of wood fibers, sold by the company Korsnaes, are deposited on the veil of continuous filaments (2), these wood fibers, with a length of of the order of 3 mm, being commonly designated by the expression "fluff paste".
Une caisse aspirante (5) est disposée sous le convoyeur sous toute la surface de la tête aéraulique de distribution (4). Cette tête aspirante (5) est reliée à un générateur de vide qui permet de répartir uniformément les fibres de bois tout en préservant l'homogénéité du voile de filaments continus (2).A suction box (5) is placed under the conveyor under the entire surface of the distribution air head (4). This suction head (5) is connected to a vacuum generator which allows the wood fibers to be distributed uniformly while preserving the homogeneity of the web of continuous filaments (2).
Un rouleau presseur (non représenté), dont la vitesse est synchronisée avec ledit tapis (3), compacte l'ensemble ainsi formé.A pressure roller (not shown), the speed of which is synchronized with said belt (3), compacts the assembly thus formed.
Après compactage, on dépose à la surface du complexe un deuxième voile de filaments continus, pesant 15 g/m2' de même nature que le premier voile (2).After compaction, a second veil of continuous filaments weighing 15 g / m 2 'of the same type as the first veil (2) is deposited on the surface of the complex.
Ce voile peut être formé soit sur un même convoyeur (3), soit sur un convoyeur indépendant. Ce voile (7) est donc réparti sur la couche de fibres cellulosiques (4). De préférence, le transfert est réalisé d'une manière positive en utilisant une caisse aspirante (5a) disposée sous le convoyeur principal en regard du point de transfert.This veil can be formed either on the same conveyor (3), or on an independent conveyor. This veil (7) is therefore distributed over the layer of cellulosic fibers (4). Preferably, the transfer is carried out in a positive manner using a suction box (5a) arranged under the main conveyor opposite the transfer point.
La structure obtenue, qui pèse 65 g/m2, est éventuellement compactée au moyen d'un cylindre (8). Ce compactage peut éventuellement être réalisé au moyen d'une rampe additionnelle d'injecteurs hydrauliques.The structure obtained, which weighs 65 g / m2, is optionally compacted by means of a cylinder (8). This compaction can possibly be achieved by means of an additional ramp of hydraulic injectors.
Le complexe est ensuite transféré sur le convoyeur (10) de l'unité de liage hydraulique (9).The complex is then transferred to the conveyor (10) of the hydraulic binding unit (9).
Une telle unité de liage comprend un convoyeur principal (10) au dessus duquel est disposé un convoyeur supérieur (11), tangent à celui-ci, et à l'intérieur duquel est disposé un injecteur hydraulique (12), délivrant 4000 jets d'eau par mètre, ces jets ayant un diamètre de 130 microns et une vitesse de 34 mètres par seconde.Such a binding unit comprises a main conveyor (10) above which is disposed an upper conveyor (11), tangent thereto, and inside which is disposed a hydraulic injector (12), delivering 4000 jets of water per meter, these jets having a diameter of 130 microns and a speed of 34 meters per second.
Le « sandwich » ainsi compacté et mouillé est traité sur sa face supérieure par six injecteurs (13) hydrauliques, disposés en série qui projettent des jets d'eau de 120 microns de diamètre espacés les uns des autres de 0,6 mm à des vitesses respectives de 110, 125, 140, 140, 140,140 m/seconde.The “sandwich” thus compacted and wetted is treated on its upper face by six hydraulic injectors (13), arranged in series which project water jets of 120 microns in diameter spaced from one another by 0.6 mm at speeds respectively 110, 125, 140, 140, 140,140 m / second.
Le complexe traité est alors transféré par retournement sur un cylindre (14) autour duquel sont disposés quatre injecteurs hydrauliques (15) qui projettent des jets d'eau de 120 microns de diamètre espacés les uns des autres de 0,6 mm à des vitesses respectives de 125, 140, 140, 140 m/seconde.The treated complex is then transferred by inversion onto a cylinder (14) around which are arranged four hydraulic injectors (15) which project water jets of 120 microns in diameter spaced from one another by 0.6 mm at respective speeds. 125, 140, 140, 140 m / second.
Le complexe ainsi consolidé est transféré sur un convoyeur d'exprimage (16) sur lequel il est exprimé par une caisse aspirante dans laquelle règne un vide de 400 mbars.The complex thus consolidated is transferred to an expressing conveyor (16) on which it is expressed by a suction box in which there is a vacuum of 400 mbar.
Puis l'ensemble est séché à une température de 120°C par un cylindre (17) à air traversant, puis réceptionné en (18). En sortie de la ligne de production, on constate que le produit obtenu pèse environ 60 g/m2, présente une excellente homogénéité, un bon toucher, une grande souplesse et une excellente résistance à l'abrasion aussi bien à l'état sec qu'à l'état humide.Then the assembly is dried at a temperature of 120 ° C by a cylinder (17) with through air, then received at (18). At the outlet of the production line, it can be seen that the product obtained weighs approximately 60 g / m 2 , has excellent homogeneity, good feel, great flexibility and excellent abrasion resistance both in the dry state and in the dry state. 'in the wet state.
Sa capacité d'absorption d'eau est importante, de l'ordre de 850 %.Its water absorption capacity is significant, around 850%.
Une telle capacité d'absorption d'eau est comparable à des non tissés mixtes constitués de fibres discontinues et qui ont été réalisées par cardage.Such a water absorption capacity is comparable to mixed nonwovens made up of staple fibers and which have been produced by carding.
En revanche, la résistance à l'abrasion tant à l'état sec qu'à l'état humide, ainsi que les caractéristiques mécaniques, sont très supérieures.On the other hand, the abrasion resistance both in the dry state and in the wet state, as well as the mechanical characteristics, are very superior.
Un tel produit est parfaitement adapté à des applications diverses, tels que produits d'essuyage industriel ou domestique, lingettes imprégnées, casaques et champs de bloc opératoire, de telles applications étant données à titre indicatif mais non limitatif. Such a product is perfectly suited to various applications, such as industrial or domestic wiping products, impregnated wipes, gowns and operating theater drapes, such applications being given as an indication but not limiting.
