Definitions

  • the present invention relates to machines for the production of woven, knitted and non-woven patterned and non-woven textiles produced by these machines.
  • FR-2 799 214 describes a machine for producing a no woven fabric which includes a drum with a perforated side surface. The drum is driven in rotation relative to its axis.
  • the machine includes a sleeve hole which is threaded on the drum.
  • the sleeve has a ratio of the sum of the surface areas of the holes over the area of its total lateral surface which is between 5 and 75% and a diameter of the holes which is not greater than 1 mm.
  • a water jet projection device projects jets of water towards the drum in a direction substantially radial thereto and means are provided for creating a depression inside the drum, which allow air and water to be evacuated.
  • the invention remedies this drawback by a machine which allows to obtain patterned products, whose hairiness is low and is not apparent and which retains a substantially flat appearance of the patterns.
  • These machines can also be used to produce woven or knitted with patterns in natural, synthetic or artificial fibers.
  • an openwork sheath is threaded on the sleeve and has openings of which at least one dimension is greater than 2 mm.
  • At least one dimension of the openings is greater at 2 mm or better at 10 mm and, preferably, at least two dimensions mutually perpendicular openings are greater than 2 mm.
  • the sheath has a thickness between 0.1 and 2.5 mm and preferably between 0.3 and 1.0 mm.
  • the ratio of the surface of the openings to the surface total lateral of the sheath is between 10 and 70%.
  • the openings of the sheath are separated by bridges of microperforated material of holes having diameters between 50 and 500 microns. This facilitates the drainage of water, which is useful in particular when the bridges have a dimension, in particular a width, greater than 3 mm, so that it does not create defects and marks on the nonwoven.
  • the distribution of the holes in the sleeve can be random.
  • the holes can also be ordered, being aligned or staggered.
  • the sleeve can be made of a metallic fabric or synthetic material or a mixture of metallic fabric and synthetic material. We prefer that the diameter of the holes is between 200 and 800 microns.
  • the sleeve may in particular be a metallic fabric or a fabric synthetic.
  • the closed rotating drum may have a fixed body and a surface rotating side in perforated sheet or honeycomb, which allows increase jet pressure and production rate with tying better.
  • the drum can be a Sandusky bronze cylinder having helical holes. It can also be a tube of rolled perforated sheet coated with a drainage sleeve in coarse metallic fabric which ensures good uniformity of water extraction.
  • the invention relates to a nonwoven product which comprises tangled threadlike elements and in which are embossed parts with patterns.
  • the free ends of the filamentary filaments project patterned parts of a distance less than 2 mm and, preferably, less than 1.5 and the number of free ends which thus project is less than 10 / 5mm 2 , preferably 5, and better still 3.
  • We can determine said distance and said number as follows: we observe with a magnifying glass having a magnification of 8 times.
  • the upper face of the projecting parts is substantially flat, at unlike earlier patterned nonwovens in which these parts were clearly domed, in addition to the fact that they had great hairiness.
  • the curved faces of the projecting parts are placed facing the mobile foot of the device. When the movable stand comes into contact with the curved part, the first thickness value is recorded. When the foot mobile continues its descent and arrives at the lowest level of the surface of the curved part, a second thickness value is read on the device. The difference between these two values corresponds to the flatness of the parts in relief. The smaller this difference, the better the flatness.
  • the flatness of the projecting parts is between 0.1 and 1.5 mm and preferably less than 1 mm.
  • the projecting parts have each at least one dimension greater than 2 mm and, preferably, have two dimensions perpendicular to each other greater than 2.5 mm and when the intervals between two neighboring projecting parts is between 0.5 and 10, the projecting parts can be circular, oval or polygonal, but also have any logo shape.
  • Nonwovens can be made of natural or artificial or synthetic fibers.
  • Nonwovens are generally obtained by the so-called carding or aerodynamic technique, they can also consist of continuous thermoplastic filaments obtained by the so-called spunbond technique or even meltblowns.
  • Nonwovens can also be obtained by the so-called wet technique, they can also be obtained by the combination of several processes such as, for example, spunbond + carded sails, spunbond + natural fibers linked aerodynamically "airlaid”. Good results have been obtained with nonwovens of 30 to 150 g / m 2 based on viscose, viscose / polyester and cotton blends. However, this list is not exhaustive.
  • the thicknesses of the nonwovens including the protruding patterns are generally between 0.5 mm and 2.5 mm and the elevation of the protruding parts is between 0.3 and 2.0.
  • the thickness and the elevation are measured as follows: The thickness is measured by placing the nonwoven in a nonwoven thickness measuring device as recommended by the EDANA ERT 30.5-99 standard. The elevation is measured with a magnifying glass 8 times and with micrometric graduations.
  • the nonwoven has undergone a first bonding treatment on a usual machine for bonding nonwovens by water jets and immediately after is continuously transferred to the device being the invention. This preliminary treatment is not to be carried out for the products woven and knitted.
  • the jets For carrying out the treatment aimed at producing the patterns, the jets have a diameter between 80 and 170 microns and, preferably, between between 100 and 140 microns.
  • the number of jets per meter is between 1000 and 5000 and preferably between 1500 and 4000.

Abstract

The machine consists of a rotating drum (1) with a perforated lateral surface, a cover (4) with holes of under 1 mm in diameter covering 7 to 50 per cent of its surface, and an outer perforated sleeve (5) with holes (6) having at least one dimension greater than 2 mm. Outside the drum there is a system (8, 9) for delivering water jets into it, and a unit (7) for creating a depression inside the drum. The sleeve (5) is between 0.1 and 2.5 mm thick, and the holes in its surface cover between 10 and 70 per cent of its total area, being separated by bridges with micro perforations of 50 - 500 microns diameter. During operation the fabric is passed over the drum while water jets are forced through it, creating a pattern of small raised areas, the surfaces of which are flat and have few projecting fibre ends.

Description

La présente invention se rapporte aux machines de production de produits textiles tissés, tricotés et non tissés à motifs et aux non tissés produits par ces machines.The present invention relates to machines for the production of woven, knitted and non-woven patterned and non-woven textiles produced by these machines.

Aux US-A-6 055 710 et 5 768 756, on décrit des machines de production de non tissés dans lesquelles on utilise un tambour dont la surface la plus extérieure est constituée d'un manchon microperforé. Ces machines ne permettent pas d'obtenir des non tissés à motifs.In US-A-6,055,710 and 5,768,756, there are described production of nonwovens in which a drum is used whose surface the outermost consists of a microperforated sleeve. These machines do not make it possible to obtain patterned nonwovens.

Au FR-2 799 214 on décrit une machine de production d'un non tissé qui comprend un tambour à surface latérale perforée. Le tambour est entraíné en rotation par rapport à son axe. La machine comprend un manchon troué qui est enfilé sur le tambour. En pratique, le manchon a un rapport de la somme des superficies des trous à la superficie de sa surface latérale totale qui est compris entre 5 et 75% et un diamètre des trous qui n'est pas supérieur à 1 mm. Un dispositif de projection de jet d'eau projette des jets d'eau en direction du tambour dans une direction sensiblement radiale à celui-ci et il est prévu des moyens de création d'une dépression à l'intérieur du tambour, qui permettent d'en évacuer l'air et l'eau.FR-2 799 214 describes a machine for producing a no woven fabric which includes a drum with a perforated side surface. The drum is driven in rotation relative to its axis. The machine includes a sleeve hole which is threaded on the drum. In practice, the sleeve has a ratio of the sum of the surface areas of the holes over the area of its total lateral surface which is between 5 and 75% and a diameter of the holes which is not greater than 1 mm. A water jet projection device projects jets of water towards the drum in a direction substantially radial thereto and means are provided for creating a depression inside the drum, which allow air and water to be evacuated.

Cette machine permet d'obtenir des non tissés à motifs. Mais ces non tissés ont beaucoup de pilosité et perdent l'aspect sensiblement plat que l'on recherche.This machine makes it possible to obtain patterned nonwovens. But these nonwovens have a lot of hair and lose the noticeably flat appearance that we are looking for.

L'invention remédie à cet inconvénient par une machine qui permet d'obtenir des produits à motifs, dont la pilosité est faible et n'est pas apparente et qui conserve un aspect sensiblement plat des motifs. Ces machines peuvent être utilisés aussi pour produire des produits tissés ou tricotés à motifs en fibres naturelles, synthétiques ou artificielles.The invention remedies this drawback by a machine which allows to obtain patterned products, whose hairiness is low and is not apparent and which retains a substantially flat appearance of the patterns. These machines can also be used to produce woven or knitted with patterns in natural, synthetic or artificial fibers.

Suivant l'invention, une gaine ajourée est enfilée sur le manchon et a des ajours dont au moins une dimension est supérieure à 2 mm.According to the invention, an openwork sheath is threaded on the sleeve and has openings of which at least one dimension is greater than 2 mm.

D'une manière surprenante, cela permet de supprimer pratiquement la pilosité du non tissé à motifs et en rend la surface des motifs sensiblement plane.Surprisingly, this removes practically the hairiness of the patterned nonwoven and makes the surface of the patterns substantially flat.

De préférence, au moins une dimension des ajours est supérieure à 2 mm ou mieux à 10 mm et, de préférence, au moins deux dimensions perpendiculaires entre elles des ajours sont supérieures à 2 mm. Preferably, at least one dimension of the openings is greater at 2 mm or better at 10 mm and, preferably, at least two dimensions mutually perpendicular openings are greater than 2 mm.

On a obtenu de bons résultats lorsque la gaine a une épaisseur comprise entre 0,1 et 2,5 mm et, de préférence, entre 0,3 et 1,0 mm.Good results have been obtained when the sheath has a thickness between 0.1 and 2.5 mm and preferably between 0.3 and 1.0 mm.

On préfère que le rapport de la surface des ajours à la surface latérale totale de la gaine soit compris entre 10 et 70 %.We prefer that the ratio of the surface of the openings to the surface total lateral of the sheath is between 10 and 70%.

De préférence, les ajours de la gaine sont séparés par des ponts de matière microperforés de trous ayant des diamètres compris entre 50 et 500 microns. On facilite ainsi le drainage de l'eau, ce qui est utile notamment lorsque les ponts ont une dimension, notamment une largeur, supérieure à 3 mm, pour qu'il ne se crée pas de défauts et des marques sur le non tissé.Preferably, the openings of the sheath are separated by bridges of microperforated material of holes having diameters between 50 and 500 microns. This facilitates the drainage of water, which is useful in particular when the bridges have a dimension, in particular a width, greater than 3 mm, so that it does not create defects and marks on the nonwoven.

La répartition des trous dans le manchon peut être aléatoire. Les trous peuvent aussi être ordonnés, en étant alignés ou en quinconce. Le manchon peut être constitué d'un tissu métallique ou en matière synthétique ou en un mélange de tissu métallique et de matière synthétique. On préfère que le diamètre des trous soit compris entre 200 et 800 microns.The distribution of the holes in the sleeve can be random. The holes can also be ordered, being aligned or staggered. The sleeve can be made of a metallic fabric or synthetic material or a mixture of metallic fabric and synthetic material. We prefer that the diameter of the holes is between 200 and 800 microns.

Le manchon peut être notamment un tissu métallique ou un tissu synthétique.The sleeve may in particular be a metallic fabric or a fabric synthetic.

Le tambour tournant fermé peut avoir un corps fixe et une surface latérale tournante en tôle perforée ou en nid d'abeille, ce qui permet d'augmenter la pression des jets et la cadence de production avec un liage meilleur. Le tambour peut être un cylindre de bronze Sandusky ayant des trous en hélice. Ce peut être aussi un tube en tôle perforée roulée revêtu d'un manchon de drainage en tissu métallique grossier qui assure une bonne uniformité de l'extraction de l'eau.The closed rotating drum may have a fixed body and a surface rotating side in perforated sheet or honeycomb, which allows increase jet pressure and production rate with tying better. The drum can be a Sandusky bronze cylinder having helical holes. It can also be a tube of rolled perforated sheet coated with a drainage sleeve in coarse metallic fabric which ensures good uniformity of water extraction.

L'invention vise enfin un produit non tissé qui comprend des éléments filiformes enchevêtrés et dans lequel sont embossées des parties à motifs. Suivant l'invention, les extrémités libres des filaments filiformes font saillie des parties à motifs d'une distance inférieure à 2 mm et, de préférence, inférieure à 1,5 et le nombre d'extrémités libres qui font ainsi saillie est inférieure à 10/5mm2, de préférence à 5, et mieux encore à 3. On peut déterminer ladite distance et ledit nombre de la manière suivante : on observe à l'aide d'une loupe ayant un grossissement de 8 fois.Finally, the invention relates to a nonwoven product which comprises tangled threadlike elements and in which are embossed parts with patterns. According to the invention, the free ends of the filamentary filaments project patterned parts of a distance less than 2 mm and, preferably, less than 1.5 and the number of free ends which thus project is less than 10 / 5mm 2 , preferably 5, and better still 3. We can determine said distance and said number as follows: we observe with a magnifying glass having a magnification of 8 times.

La face supérieure des parties en saillie est sensiblement plane, à la différence des non tissés à motifs antérieurs dans lesquels ces parties étaient nettement bombées, outre le fait qu'elles avaient une grande pilosité. On peut mesurer la planéité de la manière suivante : On peut mesurer la planéité de la manière suivante : Le non-tissé est testé avec un appareil de mesure d'épaisseur de non-tissés tel que recommandé par la norme EDANA ERT 30.5-99. Les faces bombées des parties en saillie sont placées face au pied mobile de l'appareil. Lorsque le pied mobile arrive en contact avec la partie bombée, la première valeur d'épaisseur est enregistrée. Lorsque le pied mobile continue sa descente et arrive au niveau le plus bas de la surface de la partie bombée, une deuxième valeur d'épaisseur est lue sur l'appareil. La différence entre ces deux valeurs correspond à la planéité des parties en relief. Plus cette différence est faible et meilleure est la planéité. Suivant l'invention, la planéité des parties en saillie est comprise entre 0,1 et 1,5 mm et, de préférence, inférieure à 1 mm.The upper face of the projecting parts is substantially flat, at unlike earlier patterned nonwovens in which these parts were clearly domed, in addition to the fact that they had great hairiness. We can measure the flatness as follows: We can measure the flatness as follows: The nonwoven is tested with a thickness measurement of nonwovens as recommended by the EDANA standard ERT 30.5-99. The curved faces of the projecting parts are placed facing the mobile foot of the device. When the movable stand comes into contact with the curved part, the first thickness value is recorded. When the foot mobile continues its descent and arrives at the lowest level of the surface of the curved part, a second thickness value is read on the device. The difference between these two values corresponds to the flatness of the parts in relief. The smaller this difference, the better the flatness. next the invention, the flatness of the projecting parts is between 0.1 and 1.5 mm and preferably less than 1 mm.

On obtient de bons résultats lorsque les parties en saillie ont chacune au moins une dimension supérieure à 2 mm et, de préférence, ont deux dimensions perpendiculaires entre elles supérieures à 2,5 mm et lorsque les intervalles entre deux parties en saillie voisines est compris entre 0,5 et 10, les parties en saillie peuvent être circulaires, ovales ou polygonales, mais aussi avoir n'importe quelle forme en logo.Good results are obtained when the projecting parts have each at least one dimension greater than 2 mm and, preferably, have two dimensions perpendicular to each other greater than 2.5 mm and when the intervals between two neighboring projecting parts is between 0.5 and 10, the projecting parts can be circular, oval or polygonal, but also have any logo shape.

Les non tissés peuvent être constitués de fibres naturelles ou artificielles ou synthétiques. Les non tissés sont généralement obtenus par la technique dite de cardage ou aérodynamique, ils peuvent aussi être constitués de filaments continus thermoplastiques obtenus par la technique dite spunbond voire des meltblowns. Les non tissés peuvent aussi être obtenus par la technique dite voie humide, ils peuvent aussi être obtenus par la combinaison de plusieurs procédés comme par exemple spunbond + voiles cardés, spunbond + fibres natures liées par voie aérodynamique « airlaid ». De bons résultats ont été obtenus avec des non tissés de 30 à 150 g/m2 à base de viscose, de mélanges viscose/polyester et de coton. Mais cette liste n'est pas limitative. Les épaisseurs des non tissés y compris les motifs en saillie sont généralement comprises entre 0,5 mm et 2,5 mm et la surélévation des parties en saillie est comprise entre 0,3 et 2,0. On mesure l'épaisseur et la surélévation de la manière suivante : On mesure l'épaisseur en plaçant le non-tissé dans un appareil de mesure d'épaisseur de non-tissés tel que recommandé par la norme EDANA ERT 30.5-99. La surélévation est mesurées avec une loupe de grossissement 8 fois et à graduations micrométrique.Nonwovens can be made of natural or artificial or synthetic fibers. Nonwovens are generally obtained by the so-called carding or aerodynamic technique, they can also consist of continuous thermoplastic filaments obtained by the so-called spunbond technique or even meltblowns. Nonwovens can also be obtained by the so-called wet technique, they can also be obtained by the combination of several processes such as, for example, spunbond + carded sails, spunbond + natural fibers linked aerodynamically "airlaid". Good results have been obtained with nonwovens of 30 to 150 g / m 2 based on viscose, viscose / polyester and cotton blends. However, this list is not exhaustive. The thicknesses of the nonwovens including the protruding patterns are generally between 0.5 mm and 2.5 mm and the elevation of the protruding parts is between 0.3 and 2.0. The thickness and the elevation are measured as follows: The thickness is measured by placing the nonwoven in a nonwoven thickness measuring device as recommended by the EDANA ERT 30.5-99 standard. The elevation is measured with a magnifying glass 8 times and with micrometric graduations.

Généralement le non tissé a subi un premier traitement de liaison sur une machine habituelle pour la liaison de non tissés par jets d'eau et immédiatement après est transféré en continu sur le dispositif faisant l'objet de l'invention. Ce traitement préalable n'est pas à effectuer pour les produits tissés et tricotés.Generally the nonwoven has undergone a first bonding treatment on a usual machine for bonding nonwovens by water jets and immediately after is continuously transferred to the device being the invention. This preliminary treatment is not to be carried out for the products woven and knitted.

Pour la réalisation du traitement visant à réaliser les motifs, les jets ont un diamètre compris entre 80 et 170 microns et, de préférence, compris entre 100 et 140 microns. Le nombre de jets par mètre est compris entre 1000 et 5000 et, de préférence, entre 1500 et 4000. La pression d'eau dans les injecteurs est comprise entre 10 et 400 bars et, de préférence, entre 80 et 250 bars. En général, la dépression dans le tambour est comprise entre - 20 mbars (millibars) et -200 mbars et le tambour est entraíné à une vitesse comprise entre 1 et 400m/min.For carrying out the treatment aimed at producing the patterns, the jets have a diameter between 80 and 170 microns and, preferably, between between 100 and 140 microns. The number of jets per meter is between 1000 and 5000 and preferably between 1500 and 4000. The water pressure in the injectors is between 10 and 400 bars and preferably between 80 and 250 bars. In general, the vacuum in the drum is between - 20 mbar (millibars) and -200 mbar and the drum is driven at a speed between 1 and 400m / min.

Les exemples suivants illustrent l'invention.The following examples illustrate the invention.

Exemple 1 : Figures 2, 2a et 2bExample 1: Figures 2, 2a and 2b

On réalise un produit conforme à l'invention de la manière suivante. Une nappe d'environ 65 g/m2 composée de 100% de fibres de viscose de 1,7 dtex et de 40 mm est produite à une vitesse de 60 m/min. par une carde de type carde pour non tissés. Cette nappe est transportée par un tapis de convoyage sur une unité de liage hydraulique du type commercialisé sous la dénomination "Jetlace 3000" adaptée pour la mise en oeuvre du procédé conforme à l'invention. La nappe est compactée entre le convoyeur de transport et un premier cylindre de liage revêtu d'une enveloppe micro-perforée, les trous étant disposés de manière aléatoire, tel que décrit dans le brevet français n° 2 734 285. Lors du compactage, le voile est mouillé par l'intermédiaire de l'injecteur situé derrière le convoyeur de transport, juste après le point de compactage, injecteur qui est disposé perpendiculairement à la génératrice du cylindre. Cet injecteur est équipé d'une plaque perforée de trous de 140 microns distants les uns des autres d'une distance de 1 mm et fonctionnant à une pression de 15 bars. Le voile ainsi compacté et mouillé légèrement prélié est alors soumis à l'action de deux injecteurs hydrauliques successifs projetant des jets d'eau de 120 microns de diamètre à des vitesses croissantes de 100 et 125 m/seconde. Les jets d'eau étant espacés les uns des autres de 0,6 mm. Après traitement de liage, le voile lié subit un traitement conforme à l'invention en le faisant passer sur le tambour 1 rotatif ayant le manchon 4 et la gaine 5 : la gaine 5 présente des ajours hexagonaux de 12 mm et une épaisseur de 0,8 mm et un taux de vide (rapport de la somme des superficies des ajours à la superficie totale de la surface latérale) de 50%. Elle est ajustée sur le manchon 4 microperforé dont les trous ont un diamètre de 300 microns et une densité de trous de 100 trous par centimètre carré. Ce manchon microperforé a une épaisseur de 0,35 mm. Le voile fibreux préalablement consolidé sur le cylindre précédent est soumis à l'action de deux injecteurs successifs délivrant des jets de 120 microns de diamètre à une vitesse de 150 m/seconde, les jets étant espacés les uns des autres de 0,6 mm. Les perforations du tambour ont un diamètre de 10 mm. Le rapport de la somme des superficies des perforations à la superficie totale de la surface latérale est de 70%. Le voile est ensuite transféré sur un tapis aspirant connecté à un générateur de vide, puis séché à la température de 150°C dans un four à air traversant puis enroulé sous forme d'une bobine. On obtient un non tissé pesant environ 60 g/m2 présentant un motif hexagonal d'une bonne définition du motif hexagonal et dont les parties en saillie (motifs) sont exemptes de pilosité ou de fibres hérissées comme représenté aux figures 3 et 4. L'intervalle entre deux motifs voisins est de 3 mm. Le non tissé a une épaisseur de 0,7 mm et les motifs sont surélévés de 0,5 mm. Une observation à la loupe de cinq motifs pris au hasard montre que le nombre de poil par 5 mm2 est inférieur à 4 dans chaque motif et que la longueur des quelques poils qui apparaissent, décomptée à partir du niveau de la face supérieure du motif est inférieure à 1,5 mm. A product according to the invention is produced in the following manner. A sheet of approximately 65 g / m 2 composed of 100% viscose fibers of 1.7 dtex and 40 mm is produced at a speed of 60 m / min. by a card type card for nonwovens. This sheet is transported by a conveyor belt on a hydraulic binding unit of the type sold under the name "Jetlace 3000" suitable for carrying out the process according to the invention. The sheet is compacted between the transport conveyor and a first binding cylinder coated with a micro-perforated envelope, the holes being arranged randomly, as described in French Patent No. 2,734,285. During compaction, the veil is wetted via the injector located behind the transport conveyor, just after the compaction point, injector which is arranged perpendicular to the generator of the cylinder. This injector is equipped with a plate perforated with holes of 140 microns distant from each other by a distance of 1 mm and operating at a pressure of 15 bars. The veil thus compacted and slightly prewetted wet is then subjected to the action of two successive hydraulic injectors projecting water jets of 120 microns in diameter at increasing speeds of 100 and 125 m / second. The water jets being spaced from each other by 0.6 mm. After binding treatment, the bonded veil undergoes a treatment in accordance with the invention by passing it over the rotary drum 1 having the sleeve 4 and the sheath 5: the sheath 5 has hexagonal openings of 12 mm and a thickness of 0, 8 mm and a void ratio (ratio of the sum of the areas of the openings to the total area of the lateral surface) of 50%. It is adjusted on the microperforated sleeve 4 whose holes have a diameter of 300 microns and a hole density of 100 holes per square centimeter. This microperforated sleeve has a thickness of 0.35 mm. The fibrous web previously consolidated on the preceding cylinder is subjected to the action of two successive injectors delivering jets of 120 microns in diameter at a speed of 150 m / second, the jets being spaced from one another by 0.6 mm. The perforations of the drum have a diameter of 10 mm. The ratio of the sum of the areas of the perforations to the total area of the lateral surface is 70%. The veil is then transferred to a suction mat connected to a vacuum generator, then dried at the temperature of 150 ° C in a through air oven and then wound up in the form of a coil. A nonwoven weighing approximately 60 g / m 2 is obtained having a hexagonal pattern of good definition of the hexagonal pattern and the projecting parts (patterns) of which are free of hairiness or of bristling fibers as shown in FIGS. 3 and 4. L the interval between two neighboring patterns is 3 mm. The nonwoven has a thickness of 0.7 mm and the patterns are raised by 0.5 mm. A magnifying glass observation of five random patterns shows that the number of hairs per 5 mm 2 is less than 4 in each pattern and that the length of the few hairs that appear, counted from the level of the upper side of the pattern is less than 1.5 mm.

Exemple 2:Example 2:

Les conditions de traitement sont les mêmes que celles données dans l'exemple 1. On réalise un produit constitué par un mélange de fibres de viscose et de polyester 70/30. Les fibres ont un titre de 1,7 dtex et une longueur de 40 mm. La nappe formée pèse, à la sortie de la carde environ 65 g/m2 et après traitement environ 60 g/m2. Elle présente un motif hexagonal de bonne définition et dont les parties en relief sont exemptes de pilosité comme à l'exemple 1.The processing conditions are the same as those given in Example 1. A product is produced consisting of a mixture of viscose fibers and 70/30 polyester. The fibers have a count of 1.7 dtex and a length of 40 mm. The sheet formed weighs, at the outlet of the card about 65 g / m 2 and after treatment about 60 g / m 2 . It has a hexagonal pattern of good definition and the raised parts of which are free from hairiness as in Example 1.

Exemple comparatif : Figure 2c :Comparative example: Figure 2c:

On réalise les mêmes exemples que précédemment, mais le deuxième tambour rotatif est modifié en enlevant le manchon microperforé placé à l'intérieur de la gaine ajourée. Les produits ainsi obtenus présentent un motif de mauvaise définition et dont les parties en saillie présentent une forte pilosité et de nombreuses fibres hérissées dans le cas du non tissé en viscose et dans le cas du mélange viscose/polyester. De nombreuses fibres (15/5 mm2) sont dressées à la surface des parties en saillie et de plus ces fibres sont facilement arrachées de la surface et certaines ont une longueur de 10 mm.The same examples are carried out as above, but the second rotary drum is modified by removing the microperforated sleeve placed inside the perforated sheath. The products thus obtained have a pattern of poor definition and the protruding parts of which have high hairiness and numerous bristling fibers in the case of the viscose nonwoven and in the case of the viscose / polyester mixture. Many fibers (15/5 mm 2 ) are drawn up on the surface of the projecting parts and moreover these fibers are easily torn from the surface and some have a length of 10 mm.

Exemple 3Example 3 "Produit textile""Textile product"

Un tissu de coton de 100 g/m2 subit un traitement sur un ensemble conforme à l'invention et identique à celui des exemples 1 et 2. A une vitesse de 5 m/minute, il est soumis à l'action de deux injecteurs successifs délivrants des jets de 120 microns de diamètre à une vitesse de 243 m/seconde, les jets étant espacés les uns des autres de 0,6 mm. Le tissu est ensuite séché dans un four à air traversant à une température de 100°C.
