Abstract

Hydrophilic cotton product with front soft surface and rough reverse surface, comprises first soft external layer of fine fibers, and second rough external layer of large fibers. The product, consisting totally of cotton fibres, comprises at least one first and one second external layer, the former made of fine fibers with low micron index, forming soft surface, and the latter of larger fibers with higher micron index, forming rough surface. The surface of the external layers may be divided into stripes, with the space between the stripes of first external layer smaller than that of the second external layer, preferably 0.4-1.2 mm and 1.2-3 mm, respectively, or the second layer may have a sequence of groups of stripes, with the space between the stripes in each group 0.4-1.2 mm and the space between each group and the next one equal 1.4-4 mm. At least one of the external layers may have surface imprint, and the first external layer (soft) may comprise softening agent distributed within this layer.

L'invention a pour objet un procédé et un dispositif pour fabriquer un produit de coton hydrophile destiné notamment à un usage cosmétique : le maquillage et/ou le démaquillage de la peau.The subject of the invention is a method and a device for manufacturing a cotton wool product intended in particular for a use cosmetic: make-up and / or make-up removal from the skin.

La plupart des produits en coton présents sur le marché sont sous la forme de formats découpés : ronds, ovales ou carrés à démaquiller et ont des surfaces extérieures de composition fibreuse identique. Lors de l'utilisation de ces produits, il n'est pas possible de faire une différentiation d'usage entre les deux faces du produit si l'on souhaite utiliser une face particulière pour le maquillage par exemple en appliquant un liquide : lait, lotion ou crème, et l'autre face pour le démaquillage en nettoyant la peau par essuyage et légère friction.Most cotton products on the market are under the shape of cut formats: round, oval or square to remove and have exterior surfaces of identical fibrous composition. During the use of these products, it is not possible to make a differentiation of use between the two sides of the product if one wishes use a particular face for makeup for example applying a liquid: milk, lotion or cream, and the other side for make-up removal by cleaning the skin by wiping and light friction.

La demande de brevet N° 0 750 062 décrit des articles nettoyant la peau, qui sont à la fois doux pour la peau et suffisamment résistants pour permettre le frottement sur la peau sans provoquer d'irritations ou de lésions sur cette dernière. L'action de frotter permet l'élimination des impuretés et des cellules mortes de la surface de la peau. Ces articles comportent un substrat en non-tissé de préférence hydrolié ayant un grammage de 20 à 150 g/m2, caractérisé par un coefficient de frottement spécifique. Le substrat comprend de préférence au moins en partie des fibres longues capables de se dégager de la surface principale sous l'action du frottement tout en restant attachées au substrat. Il peut être composé d'un mélange de fibres hydrophiles et hydrophobes ou de fibres purement hydrophiles ou purement hydrophobes.Patent application No. 0 750 062 describes skin cleansing articles which are both gentle to the skin and sufficiently resistant to allow friction on the skin without causing irritation or damage to the latter. The rubbing action allows the elimination of impurities and dead cells from the surface of the skin. These articles include a nonwoven substrate, preferably hydrolyzed, having a grammage of 20 to 150 g / m 2 , characterized by a specific coefficient of friction. The substrate preferably comprises at least in part long fibers capable of emerging from the main surface under the action of friction while remaining attached to the substrate. It can be composed of a mixture of hydrophilic and hydrophobic fibers or of purely hydrophilic or purely hydrophobic fibers.

Au moins une face de l'article ou du substrat utilisé assure essentiellement la fonction de nettoyage de la peau. Elle sert également de support pour des produits nettoyants ou démaquillants tels que des lotions ou des laits de toilette. Dans le cas où l'article nettoyant la peau ne serait constitué que de ce substrat, les deux faces de l'article ne se distinguent pas et peuvent être utilisées indifféremment l'une de l'autre pour nettoyer la peau.At least one side of the article or substrate used ensures basically the skin cleansing function. It also serves of support for cleansers or make-up removers such as lotions or toilet milks. In case the skin cleansing article would consist only of this substrate, the two faces of the article do not not differentiate and can be used interchangeably to cleanse the skin.

La demande de brevet européen N° 0 851 052 révèle un tampon à démaquiller en coton à usage notamment cosmétique comprenant au moins deux couches. Afin d'éviter la perte des fibres tout en maintenant une qualité de douceur et d'absorption, les fibres des couches extérieures sont plus longues que celles de la ou des couches centrales. L'épaisseur de la ou des couches centrales est de préférence supérieure à l'épaisseur des couches extérieures. De tels produits ne présentent pas non plus de faces distinctes permettant une utilisation spécifique par face.European patent application No. 0 851 052 discloses a stamp to removing make-up from cotton, especially for cosmetic use, including minus two layers. In order to avoid fiber loss while maintaining a quality of softness and absorption, the fibers of the outer layers are longer than those of the central layer (s). The thickness of the central layer (s) is preferably greater than the thickness outer layers. Nor do such products exhibit separate sides allowing specific use per side.

Les produits de coton de démaquillage sont le plus souvent composés d'un mélange de fibres de coton de différentes qualités ou d'un mélange de fibres de coton et d'autres fibres selon le produit recherché ou le procédé de fabrication utilisé. De tels produits sont de composition homogène dans toute leur épaisseur. Certains autres produits sont constitués de plusieurs couches ou nappes. Mais il ressort effectivement de ce qui précède que les deux couches extérieures sont toujours de composition identique et ne peuvent pas être différentiées.Cotton cleansing products are most often composed of a mixture of cotton fibers of different qualities or a blend of cotton fibers and other fibers depending on the product sought or the manufacturing process used. Such products are of composition homogeneous throughout their thickness. Some other products are made up of several layers or layers. But it does appear from the above that the two outer layers are always of identical composition and cannot be differentiated.

Il existe un besoin en produits de coton présentant deux faces différentes permettant une différentiation d'usage entre les deux faces, en particulier d'usage cosmétique : une face pour le démaquillage ou nettoyage de la peau et une face pour le maquillage par application de produit sur la peau.There is a need for cotton products with two sides different allowing a differentiation of use between the two faces, in particular for cosmetic use: one side for removing make-up or cleansing of the skin and one side for makeup by applying product on the skin.

Dans le domaine de l'essuyage industriel, la demande de brevet européen N° 0 826 811 propose un matériau complexe non-tissé absorbant comportant une face souple et une face rugueuse. Ce matériau est constitué d'au moins deux nappes fibreuses superposées, liées entre elles par interpénétration des fibres dans le sens de l'épaisseur. Mais la première nappe est constituée pour tout ou partie de fibres synthétiques thermofusibles sélectionnées de préférence dans la classe des polyoléfines et la seconde nappe est constituée de fibres naturelles et/ou artificielles et/ou synthétiques plus fines que les fibres de la première nappe. Les fibres synthétiques entrant dans la composition de la première nappe permettent de réaliser la surface grattante de l'article. Cet effet grattant est obtenu par réorientation des fibres synthétiques afin de présenter des extrémités libres ou bouclettes apparentes sur une face extérieure et par fusion des extrémités libres des fibres synthétiques.In the field of industrial wiping, the patent application European N ° 0 826 811 offers a complex nonwoven material absorbent having a flexible face and a rough face. This material consists of at least two superimposed fibrous layers, linked between them by interpenetration of the fibers in the thickness direction. But the first layer consists of all or part of synthetic fibers hot fuses preferably selected from the class of polyolefins and the second layer consists of natural fibers and / or artificial and / or synthetic finer than the fibers of the first tablecloth. Synthetic fibers used in the composition of the first tablecloth to achieve the scraping surface of the article. This effect scratching is obtained by reorientation of synthetic fibers in order to have free ends or loops visible on one side exterior and by fusion of the free ends of the synthetic fibers.

Ce produit n'est pas destiné à un usage cosmétique mais est adapté pour réaliser des produits d'essuyage semi-décapants ou très absorbants.This product is not intended for cosmetic use but is suitable to make semi-scouring or very absorbent wiping products.

L'invention a pour objet un procédé pour fabriquer un produit de coton hydrophile dont les couches extérieures comportent en surface des stries formées par liage hydraulique. Le liage hydraulique est réalisé au moyen de jets d'eau.The subject of the invention is a method for manufacturing a product of hydrophilic cotton, the outer layers of which have streaks formed by hydraulic bonding. Hydraulic tying is carried out at by means of water jets.

Ce procédé est caractérisé par le fait que les jets d'eau du moyen de liage hydraulique forment des groupes avec des jets espacés entre eux d'une distance comprise entre 0,4 et 1,2 mm, les groupes de jets étant espacés les uns des autres d'une distance comprise entre 1,2 et 4 mm.This process is characterized by the fact that the water jets of the means of hydraulic tying form groups with jets spaced apart from a distance between 0.4 and 1.2 mm, the groups of jets being spaced from each other by a distance between 1.2 and 4 mm.

L'invention a également pour objet un procédé de fabrication d'un produit de coton hydrophile à partir d'une nappe à au moins deux couches selon lequel on applique un premier moyen de liage hydraulique des fibres sur une face puis un second moyen de liage hydraulique sur l'autre face de la nappe. Ce procédé est caractérisé par le fait que les jets d'eau du premier moyen de liage hydraulique sont espacés d'une distance comprise entre 0,4 et 1,2 mm et les jets d'eau du second moyen de liage hydraulique forment des groupes dans lesquels les jets espacés sont espacés les uns des autres d'une distance comprise entre 0,4 et 1,2 mm, les groupes de jets étant espacés les uns des autres d'une distance comprise entre 1,2 et 4 mm. The invention also relates to a method for manufacturing a cotton wool product from two or more layers layers according to which a first means of hydraulic binding is applied fibers on one side then a second hydraulic bonding means on the other side of the tablecloth. This process is characterized by the fact that the jets of water from the first hydraulic tying means are spaced a distance apart between 0.4 and 1.2 mm and the water jets of the second binding means hydraulics form groups in which the spaced jets are spaced from each other by a distance between 0.4 and 1.2 mm, the groups of jets being spaced from each other by a distance between 1.2 and 4 mm.

Selon une caractéristique de ce procédé, chaque couche extérieure est hydroliée au moyen de jets d'eau dont les axes sont espacés les uns des autres d'une distance donnée, cette distance étant différente entre les jets utilisés pour la première couche et les jets utilisés pour la seconde couche de manière à obtenir des couches extérieures comportant en surface des stries avec un écartement différent.According to a characteristic of this process, each outer layer is hydroliated by means of water jets whose axes are spaced apart others by a given distance, this distance being different between the jets used for the first layer and jets used for the second layer so as to obtain outer layers comprising streak surface with different spacing.

D'autres caractéristiques et avantages de l'invention apparaítront plus en détails dans la description qui suit et en référence aux dessins annexés dans lesquelles :

  • la figure 1 représente un produit présentant de plus des faces comportant des stries d'écartement différent ; et
  • la figure 2 représente schématiquement la surface d'une lame perforée d'un dispositif d'hydroliage dans lequel la lame est perforée de trous suivant une séquence.
Other characteristics and advantages of the invention will appear in more detail in the description which follows and with reference to the appended drawings in which:
  • Figure 1 shows a product further having faces with streaks of different spacing; and
  • FIG. 2 schematically represents the surface of a perforated blade of a hydroliage device in which the blade is perforated with holes in a sequence.

Les couches ou nappes de coton formant le produit selon l'invention peuvent être de grammage identique ou différent. Par exemple, la première couche constituée de fibres douces et ayant un indice micronaire faible peut être d'un grammage compris entre 10 et 40 g/m2 et la seconde couche constituée de fibres ayant un effet grattant peut être d'un grammage compris entre 10 et 300 g/m2. Inversement, la couche constituée de fibres douces peut avoir un grammage compris entre 10 et 300 g/m2 et la couche constituée de fibres ayant un effet grattant, un grammage compris entre 10 et 40 g/m2.The cotton layers or tablecloths forming the product according to the invention can be of identical or different grammage. For example, the first layer consisting of soft fibers and having a low micron index may be of a grammage between 10 and 40 g / m 2 and the second layer consisting of fibers having a scraping effect may be of a grammage between 10 and 300 g / m 2 . Conversely, the layer consisting of soft fibers may have a grammage between 10 and 300 g / m 2 and the layer consisting of fibers having a scraping effect, a grammage between 10 and 40 g / m 2 .

Le produit peut également comporter plus de deux couches. Une ou plusieurs couches centrales sont alors disposées entre les deux couches extérieures Le procédé de fabrication des produits, consiste à préparer au moins deux nappes de fibres de coton formant les deux couches extérieures du produit l'une d'indice micronaire faible, l'autre d'indice micronaire plus élevé. La différence entre les indices micronaires des deux couches extérieures est au moins égale à 1 µg/pouce. Les nappes peuvent être constituées directement à partir de coton hydrophile et blanchi. Elles peuvent aussi être obtenues à partir de coton brut écru, puis traitées chimiquement afin d'obtenir l'hydrophilie et le blanchiment. Après formation des nappes ou nappage, les nappes de coton sont superposées et sont ensuite associées. On associe les nappes par hydroliage, c'est à dire au moyen de jets d'eau à haute pression combinés à un exprimage par le vide. Une telle association peut être effectuée sur un dispositif commercialisé par la société ICBT-PERFOJET, Grenoble, France. Cette dernière technique permet à la fois l'association des deux nappes entre-elles et la liaison d'au moins une surface de la nappe diminuant ainsi le peluchage des produits.The product can also have more than two layers. A or several central layers are then placed between the two outer layers The product manufacturing process consists of prepare at least two layers of cotton fibers forming the two outer layers of the product, one with a low micron index, the other higher micronaire index. The difference between the indices micronaires of the two outer layers is at least equal to 1 g / inch. The tablecloths can be formed directly from hydrophilic and bleached cotton. They can also be obtained from unbleached raw cotton, then chemically treated to obtain hydrophilicity and laundering. After tablecloths are formed or lapped, the cotton are superimposed and are then associated. We combine the tablecloths by hydroliage, i.e. by means of high pressure water jets combined with vacuum expression. Such an association can be performed on a device marketed by the company ICBT-PERFOJET, Grenoble, France. The latter technique allows both the association of the two layers together and the connection of at least one surface of the sheet thus reducing the fluffing of the products.

Cette étape d'hydroliage, dans le cas d'une fibre écrue qui va être traitée chimiquement, peut intervenir juste après l'étape d'imprégnation de la nappe comme cela est décrit dans la demande de brevet européen n° 0 735 175. Elle peut aussi être placée en phase finale de rinçage suivant le brevet européen n° 0 805 888 au nom de la demanderesse.This hydroliage step, in the case of an unbleached fiber which will be chemically treated, can intervene just after the impregnation step tablecloth as described in European patent application no. 0 735 175. It can also be placed in the final rinsing phase following European Patent No. 0 805 888 in the name of the applicant.

Des produits en formats sont ensuite découpés dans les nappes, ainsi associées, par tout moyen classique.Products in formats are then cut from the tablecloths, thus associated, by any conventional means.

En prenant et en touchant le produit, l'utilisatrice peut différencier la face douce de la face la plus grattante.By taking and touching the product, the user can differentiate the soft side of the most scratchy side.

Afin d'accentuer cette différence, on peut pulvériser un agent adoucissant uniquement sur la face douce du produit. De ce fait, la composition de la première couche extérieure de coton ayant un faible indice micronaire comprendra un agent adoucissant réparti essentiellement en surface de cette couche.In order to accentuate this difference, an agent can be sprayed softening only on the soft side of the product. Therefore, the composition of the first outer layer of cotton having a low micronaire index will include a distributed softening agent essentially on the surface of this layer.

Il est possible de prévoir une différentiation visuelle du produitIt is possible to provide a visual differentiation of the product

On utilise la technique d'hydroliage déjà utilisée pour associer les nappes et éviter le peluchage, pour différencier visuellement les deux faces du produit.The hydroliage technique already used is used to combine the tablecloths and avoid linting, to visually differentiate the two sides of the product.

Ceci permet au moyen d'une seule technique de remplir trois fonctions différentes.This allows one technique to fill three different functions.

Les différentes couches sont préparées, puis superposées ; l'ensemble est imprégné. Les deux couches extérieures sont ensuite hydroliées l'une après l'autre sur des toiles sans fin ou des cylindres.The different layers are prepared, then superimposed; the whole is impregnated. The two outer layers are then hydroleumed one after the other on endless canvases or cylinders.

Le procédé d'hydroliage permet de traiter différemment les deux faces. En effet, les jets d'eau à haute pression utilisés pour entrelacer les fibres des couches extérieures, marquent la surface de ces couches de stries visibles à l'oeil nu, dont l'écartement correspond à la distance entre les axes des jets. Plus précisément, le dispositif d'hydroliage comprend une pompe à haute pression alimentant un injecteur placé transversalement au défilement de la nappe ou couche de fibres, sur toute sa largeur. L'injecteur consiste en un volume d'eau sous pression, fermé par une lame d'acier qui est perforée de trous calibrés produisant des jets sous la forme de fines aiguilles d'eau à haute pression projetées perpendiculairement à la surface de la nappe de fibres. Ces fins jets emmêlent les fibres. Les trous perforés dans cette lame d'acier (communément dénommée "strip") ont un diamètre allant de 100 à 200 µm de préférence 120 à 140 µm et sont régulièrement espacés. La distance entre les axes de deux trous consécutifs de la lame d'acier est en général comprise entre 0,5 et 3 mm, le plus souvent entre 0,6 et 1 mm. La position de l'injecteur étant fixe et la nappe ou couche de coton défilant sous ce dernier, on observe sur la surface de la couche, une série de stries ou sillons parallèles correspondant au passage sous les jets.The hydroliage process allows the two to be treated differently faces. Indeed, the high pressure water jets used to interlace the fibers of the outer layers, mark the surface of these layers of streaks visible to the naked eye, the spacing of which corresponds to the distance between the axes of the jets. More specifically, the hydroliage device comprises a high pressure pump supplying an injector placed transversely to the travel of the ply or layer of fibers, over all its width. The injector consists of a closed volume of pressurized water by a steel blade which is perforated with calibrated holes producing jets in the form of fine needles of high pressure water projected perpendicular to the surface of the fiber sheet. These fine jets entangle the fibers. The holes punched in this steel blade (commonly called "strip") have a diameter ranging from 100 to 200 µm preferably 120 to 140 µm and are regularly spaced. The distance between the axes of two consecutive holes in the steel blade is in generally between 0.5 and 3 mm, most often between 0.6 and 1 mm. The position of the injector being fixed and the tablecloth or layer of cotton moving under the latter, we observe on the surface of the layer, a series of streaks or parallel grooves corresponding to the passage under the jets.

Il est ainsi possible de modifier la distance entre les axes des trous de la lame d'un dispositif d'hydroliage utilisé pour le traitement d'une couche extérieure par rapport à l'autre dispositif utilisé pour le traitement de l'autre couche. It is thus possible to modify the distance between the axes of the holes of the blade of a hydroletting device used for the treatment of a outer layer relative to the other device used for processing on the other layer.

Afin d'obtenir un aspect différent entre les deux faces du produit, on peut par exemple utiliser pour une face, un dispositif d'hydroliage dont la lame est perforée avec une distance importante entre les trous de 1,2 à 3 mm, de préférence de 1,6 à 2,5 mm, et pour l'autre face, un dispositif dont la lame est perforée avec une distance entre les trous comprise entre 0,4 et 1,2 mm, de préférence entre 0,5 et 0,8 mm. Les stries ou sillons ayant un écartement de 1,2 à 3 mm seront plus visibles sur la face ainsi traitée que les stries de l'autre face.In order to obtain a different appearance between the two sides of the product, one can for example use for a face, a hydroliage device of which the blade is perforated with a significant distance between the holes from 1.2 to 3 mm, preferably 1.6 to 2.5 mm, and for the other side, a device the blade of which is perforated with a distance between the holes of between 0.4 and 1.2 mm, preferably between 0.5 and 0.8 mm. Streaks or grooves with a spacing of 1.2 to 3 mm will be more visible on the face as well treated as the streaks on the other side.

On obtient alors une face finement striée et l'autre plus grossièrement.We then obtain a finely striated face and the other more roughly.

Un exemple de produit présentant cette différentiation est illustrée par la figure 1.An example of a product exhibiting this differentiation is illustrated. by figure 1.

Ce produit 21 comprend une première couche extérieure 22 d'un indice micronaire de 3,4 µg/pouce et d'un grammage de 25 g/m2, une seconde couche extérieure 23 d'un indice micronaire de 6,8 µg/pouce et d'un grammage de 25 g/m2 et une couche centrale 24 de 200 g/m2.This product 21 includes a first outer layer 22 with a micron index of 3.4 µg / inch and a basis weight of 25 g / m 2 , a second outer layer 23 with a micron index of 6.8 µg / inch and a grammage of 25 g / m 2 and a central layer 24 of 200 g / m 2 .

La face 25 de la couche extérieure 22 présente des stries 26 ayant un écartement d1 de 0,6 mm et la face 27 de la couche extérieure 23 présente des stries 28 ayant un écartement d2 de 2 mm.The face 25 of the outer layer 22 has grooves 26 having a spacing d 1 of 0.6 mm and the face 27 of the outer layer 23 has grooves 28 having a spacing d 2 of 2 mm.

L'utilisatrice est ainsi guidée pour discerner la face douce de la face plus grattante du produit afin d'utiliser chacune des faces du produit dans sa bonne destination : maquillage et/ou démaquillage.The user is thus guided to discern the soft side of the face more scratching of the product in order to use each side of the product in its good destination: make-up and / or make-up removal.

Cependant, l'augmentation de la distance entre les trous de la lame perforée a pour conséquence directe une diminution du nombre de trous et donc un apport d'énergie plus faible sur la nappe qu'il n'est pas toujours possible de compenser par une augmentation de la pression d'eau dans l'injecteur. Cette diminution de l'énergie transmise à la nappe peut provoquer une augmentation du peluchage par rapport au résultat obtenu sur une nappe ayant subi une étape d'hydroliage au moyen d'une lame perforée dont la distance entre les trous est faible et uniforme.However, increasing the distance between the holes in the blade perforated has the direct consequence of reducing the number of holes and therefore a lower energy supply on the water table than it is not always possible to compensate by increasing the water pressure in the injector. This reduction in the energy transmitted to the water table can cause an increase in linting compared to the result obtained on a sheet having undergone a hydroliage step by means of a blade perforated, the distance between the holes is small and uniform.

Afin de limiter cette augmentation du peluchage, on utilise, conformément à l'invention, une lame perforée de trous selon une séquence, par exemple des groupes de 6 trous espacés de 0,6 mm, chaque groupe étant espacé du suivant de 1,8 mm. On obtient ainsi une face où les stries sont bien visibles car elles apparaissent avec un écartement large : le pas est important de l'ordre de 4,8 mm. L'augmentation du peluchage est ainsi limitée grâce à une fréquence moyenne de trous supérieure à celle d'une lame régulièrement perforée par exemple à une distance de 1,8 mm. Dans cet exemple de séquence, le nombre moyen de trous par mètre est de 1250, alors que dans le cas de trous régulièrement espacés à une distance de 1,8 mm, ce nombre est de 555. Pour un diamètre de trou et une pression donnés, on pourra donc apporter plus du double de l'énergie avec la lame perforée selon cette séquence, par rapport à la lame régulièrement perforée à une distance de 1,8 mm.In order to limit this increase in linting, we use, according to the invention, a blade perforated with holes according to a sequence, for example groups of 6 holes spaced 0.6 mm apart, each group being spaced next 1.8 mm. We thus obtain a face where the streaks are clearly visible because they appear with a spacing wide: the pitch is important on the order of 4.8 mm. The increase in fluffing is thus limited thanks to an average frequency of holes greater than that of a regularly perforated blade for example at a distance of 1.8 mm. In this example sequence, the average number of holes per meter is 1250, while in the case of regular holes spaced at a distance of 1.8 mm, this number is 555. For a given hole diameter and pressure, so we can add more double the energy with the perforated blade in this sequence, by compared to the regularly perforated blade at a distance of 1.8 mm.

La figure 2 illustre une lame perforée de trous selon une séquence, ici par groupes de 5 trous espacés d'une distance e1 égale à 0,6 mm, chaque séquence ou groupe de trous étant espacé de la suivante d'une distance e2 égale à 1,8 mm.FIG. 2 illustrates a strip perforated with holes according to a sequence, here in groups of 5 holes spaced by a distance e 1 equal to 0.6 mm, each sequence or group of holes being spaced from the next by a distance e 2 equal to 1.8 mm.

Ceci se traduit au niveau du produit par une première couche extérieure qui comporte des stries avec un certain écartement compris entre 0,4 et 1,2 mm (ici 0,6 mm) et une seconde couche extérieure qui comporte des stries selon une séquence comprenant plusieurs groupes de stries, chaque groupe de stries ayant un certain écartement entre les stries, cet écartement étant compris entre 0,4 et 1,2 mm (ici 0,6 mm) et chaque groupe étant espacé du groupe suivant d'une distance comprise entre 1,2 et 4 mm (ici 1,8 mm).This results in a first layer at the product level exterior which has ridges with a certain spacing included between 0.4 and 1.2 mm (here 0.6 mm) and a second outer layer which has streaks in a sequence that includes multiple groups of streaks, each group of streaks having a certain spacing between the streaks, this spacing being between 0.4 and 1.2 mm (here 0.6 mm) and each group being spaced from the next group by a distance between 1.2 and 4 mm (here 1.8 mm).

L'utilisatrice dispose ainsi d'un produit de coton dont les deux faces se distinguent, qui garde ses qualités de résistance mécanique, résistance au peluchage, cohésion (résistance au délaminage) et douceur même si l'une des faces a un effet plus grattant que l'autre pour le nettoyage.The user thus has a cotton product with two sides stand out, which retains its qualities of mechanical resistance, resistance fluff, cohesion (resistance to delamination) and softness even if one side has a more scratching effect than the other for cleaning.
