Definitions

  • the subject of the invention is a method and a device for producing a hydrophilic cotton product intended in particular for cosmetic use: makeup and / or make-up removal of the skin.
  • Patent Application No. 0 750 062 discloses skin-cleaning articles which are both gentle to the skin and sufficiently strong to allow friction on the skin without causing irritation or injury to the skin. The scrubbing action allows the removal of impurities and dead cells from the surface of the skin.
  • These articles comprise a nonwoven substrate preferably hydrolized having a basis weight 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 disengaging from the main surface under the action of friction while remaining attached to the substrate. It may be composed of a mixture of hydrophilic and hydrophobic fibers or purely hydrophilic or purely hydrophobic fibers.
  • At least one face of the article or substrate used essentially provides the cleaning function of the skin. It also serves as a support for cleansing or makeup removers such as lotions or milkshakes. In the case where the article cleaning the skin consists only of this substrate, the two faces of the article are not distinguishable and can be used indifferently from one another to clean the skin.
  • European Patent Application No. 0 851 052 reveals a cotton makeup remover for cosmetic use comprising at least two layers.
  • the fibers of the outer layers are longer than those of the central layer or layers.
  • the thickness of the central layer or layers is preferably greater than the thickness of the outer layers.
  • Such products also have no distinct faces allowing a specific use per face.
  • Makeup removal cotton products are most often composed of a mixture of cotton fibers of different qualities or a mixture of cotton fibers and other fibers depending on the desired product or the manufacturing process used. Such products are of composition homogeneous throughout their thickness. Some other products consist of several layers or tablecloths. But it is clear from the above that the two outer layers are still of identical composition and can not be differentiated.
  • the European patent application No. 0 826 811 proposes an absorbent nonwoven complex material comprising a flexible face and a rough face.
  • This material consists of at least two superposed fibrous layers, interconnected by interpenetration of the fibers in the direction of the thickness.
  • the first web consists of all or part of synthetic hot melt fibers preferably selected from the class of polyolefins and the second web is made of natural and / or artificial and / or synthetic fibers finer than the fibers of the first web.
  • the synthetic fibers used in the composition of the first sheet make it possible to produce the scratching surface of the article. This scraping effect is obtained by reorientation of the synthetic fibers to present free ends or loops apparent on an outer face and by melting the free ends of the synthetic fibers.
  • This product is not intended for cosmetic use but is suitable for making semi-stripping or highly absorbent wiping products.
  • the invention relates to a process for producing a hydrophilic cotton product whose outer layers have on the surface streaks formed by hydraulic bonding. Hydraulic binding is achieved by means of water jets, produced by an injector comprising a perforated plate of calibrated holes.
  • the subject of the invention is also a process for producing a hydrophilic cotton product from a web having at least two layers, in which a first means for hydraulically binding the fibers is applied to one face and then a second means of binding. hydraulic on the other side of the sheet.
  • This method is characterized in that the jets of water of the first hydraulic binding means are spaced a distance of between 0.4 and 1.2 mm and the jets of water of the second hydraulic binding means form groups wherein 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 of between 1.2 and 4 mm.
  • each outer layer is hydrolized by means of water jets whose axes are spaced from each other by a given distance, this distance being different between the jets used for the first layer and the jets used. for the second layer so as to obtain outer layers having on the surface streaks with a different spacing.
  • the cotton layers or plies forming the product according to the invention may be of identical or different weight.
  • the first layer made of soft fibers and having a low micronaire index may be of a grammage of between 10 and 40 g / m 2 and the second layer of fibers having a scraping effect may be of a grammage between 10 and 300 g / m 2 .
  • the layer made of soft fibers may have a grammage of between 10 and 300 g / m 2 and the layer consisting of fibers having a scraping effect, a basis weight between 10 and 40 g / m 2 .
  • the product may also have more than two layers. One or more central layers are then arranged between the two outer layers.
  • the product manufacturing process consists of preparing at least two layers of cotton fibers forming the two outer layers of the product one of low micronaire index, the other micronaire index higher. The difference between the micronaire indices of the two outer layers is at least equal to 1 ⁇ g / inch.
  • the webs can be made directly from hydrophilic cotton and bleached. They can also be obtained from unbleached raw cotton and then chemically treated to obtain hydrophilicity and bleaching. After formation of the plies or topping, the cotton plies are superimposed and are then associated. The plies are combined by hydrolysis, that is to say by means of high-pressure water jets combined with vacuum voicing.
  • This hydrolysis step in the case of an unbleached fiber that will be chemically treated, may take place immediately after the step of impregnating the sheet as described in the European patent application no. 0 735 175 . It can also be placed in the final rinse phase according to the European patent no. 0 805 888 in the name of the plaintiff.
  • Products in formats are then cut into the webs, thus associated, by any conventional means.
  • the user can differentiate the soft face from the most scratching face.
  • the composition of the first outer layer of cotton having a low micron number will comprise a softening agent distributed essentially at the surface of this layer.
  • the hydrolysis technique already used to combine the plies and to avoid linting is used to visually differentiate the two faces of the product.
  • the different layers are prepared, then superimposed; the whole is impregnated.
  • the two outer layers are then hydrolized one after the other on endless cloths or cylinders.
  • the hydrolysis device comprises a high pressure pump feeding an injector placed transversely to the scroll of the sheet or layer of fibers, over its entire width.
  • the injector consists of a volume of water under pressure, closed by a steel plate which is perforated with calibrated holes producing jets in the form of fine high pressure water needles projected perpendicular to the surface of the water table. fibers. These fine jets entangle the fibers.
  • the holes perforated in this steel strip have a diameter ranging from 100 to 200 microns, preferably 120 to 140 microns and are regularly spaced.
  • the distance between the axes of two consecutive holes of the steel strip is generally between 0.5 and 3 mm, most often between 0.6 and 1 mm.
  • a hydrolysis device whose blade is perforated with a large distance between the holes of 1.2 to 3 mm, preferably from 1.6 to 2.5 mm, and for the other face, a device whose blade 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 furrows having a spacing of 1.2 to 3 mm will be more visible on the face thus treated than the streaks on the other side.
  • FIG. 1 An example of a product presenting this differentiation is illustrated by the figure 1 .
  • This product 21 comprises a first outer layer 22 with a micronaire index of 3.4 ⁇ g / inch and a basis weight of 25 g / m 2 , a second outer layer 23 with a micronaire index of 6.8 ⁇ g / inch and a basis weight of 25 g / m 2 and a central layer 24 of 200 g / m 2 .
  • the face 25 of the outer layer 22 has ridges 26 having a spacing d 1 of 0.6 mm and the face 27 of the outer layer 23 has ridges 28 having a spacing d 2 of 2 mm.
  • the increase in the distance between the holes of the perforated plate has the direct consequence of a reduction in the number of holes and therefore a lower energy input on the sheet which can not always be compensated by a increase of the water pressure in the injector.
  • This reduction in the energy transmitted to the sheet can cause an increase in lint compared to the result obtained on a sheet having undergone a hydrolysis step by means of a perforated blade whose distance between the holes is small and uniform.
  • a perforated plate of holes is used in a sequence, for example groups of 6 holes spaced 0.6 mm apart, each group being spaced from the next of 1.8. mm. This gives a face where the streaks are clearly visible because they appear with a wide spacing: the pitch is important on the order of 4.8 mm.
  • the increase in lint 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.
  • the average number of holes per meter is 1250, while in the case of holes evenly spaced at a distance of 1.8 mm, this number is 555. For a given hole diameter and pressure we will be able to bring more double the energy with the perforated blade according to this sequence, compared to the regularly perforated blade at a distance of 1.8 mm.
  • the figure 2 illustrates a perforated plate of holes in a sequence, here in groups of 5 holes spaced 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.
  • first outer layer which has ridges with a certain spacing between 0.4 and 1.2 mm (here 0.6 mm) and a second outer layer which comprises streaks in a sequence comprising several groups of grooves, each group of grooves having a certain spacing between the grooves, this gap being between 0.4 and 1.2 mm (in this case 0.6 mm) and each group being spaced from the following group by a distance of between 1.2 and 4 mm (here 1.8 mm).
  • the user thus has a cotton product whose two faces are distinguished, which retains its qualities of mechanical strength, resistance to lint, cohesion (resistance to delamination) and softness even if one of the faces has a more scratching effect than the other for cleaning.
