Definitions

  • the subject of the invention is a cotton wool product made up of one hundred one hundred cotton fibers and intended in particular for cosmetic use: make-up and / or removing makeup from the skin.
  • Patent application No. 0 750 062 describes skin cleansing articles which are both gentle on 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.
  • At least one side of the article or substrate used essentially ensures the skin cleansing function. It also serves as a support for products cleansers or makeup removers such as lotions or toilet milks. In the case where the article cleaning the skin would consist only of this substrate, the two faces of the article is indistinguishable and can be used interchangeably to cleanse the skin.
  • European patent application No. 0 851 052 discloses a pad for removing makeup cotton, especially for cosmetic use, comprising at least two layers. To avoid fiber loss while maintaining a quality of softness and absorption, the fibers of the outer layers are longer than those of the layer (s) power stations. The thickness of the central layer (s) is preferably greater than the thickness of the outer layers. Nor do such products exhibit separate sides allowing specific use per side.
  • Cotton cleansing 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 product sought or the manufacturing process used. Of such products are of homogeneous composition throughout their thickness. Some others products consist of several layers or layers. But it does appear from the above that the two outer layers are always of composition identical and cannot be differentiated.
  • the European patent application N ° 0 826 811 proposes a complex absorbent nonwoven material comprising one side flexible and a rough face.
  • This material consists of at least two layers superimposed fibers, linked together by interpenetration of fibers in the direction of thickness.
  • the first layer consists of all or part of fibers hot-melt synthetics preferably selected from the class of polyolefins and the second layer consists of natural and / or artificial fibers and / or synthetic finer than the fibers of the first layer.
  • Fibers synthetics used in the composition of the first layer make it possible to produce the scraping surface of the article. This scratching effect is obtained by reorientation of the synthetic fibers to present free ends or loops visible on an outer face and by fusion of the free ends of the synthetic fibers.
  • This product is not intended for cosmetic use but is suitable for make semi-scouring or very absorbent wiping products.
  • the object of the invention is to provide a cotton product for removing makeup. comprising two separate faces.
  • a first face is described as scratching and has for the function of cleaning the skin, in particular for removing make-up, for example using a milk or lotion.
  • the other side is soft and allows the application of a make-up product, milk, lotion or cream on the face or skin. Differentiation of the faces is essentially done by touch and if necessary, in addition, visually.
  • the invention also aims to provide a "natural" product consisting only natural fibers without the addition of artificial and / or synthetic fibers, nor of binder, which also makes it easy to recycle the scrap produced during of the manufacturing process.
  • the subject of the invention is a cotton wool product made up of one hundred hundred cotton fibers comprising at least a first and a second layer exterior.
  • the first layer is made up of fine fibers with a low micron index forming one side soft and the second layer consists of fibers with a micron index higher forming a scraping face.
  • the micronaire index represents the average mass of fibers per unit of length, in ⁇ g / inch, of a cotton product sample tested. This index is directly related to the middle section of the fibers. It defines the size of the fibers of cotton and is measured using a measuring device such as SHEFFIELD Micronaire. Further details on this index and its measurement method are given in the description which follows.
  • the first layer outer has a micronaire index between 2 to 5 ⁇ g / inch and the second outer layer has a micron number between 4 to 10 ⁇ g / inch, the difference between the micron indices of the two outer layers being at least 1 ⁇ g / inch.
  • the first layer has a micronaire index between 2.8 and 4.2 ⁇ g / inch and the second layer present a micronaire index between 5 and 8.5 ⁇ g / inch.
  • the outer layers have a grammage of at least 8 g / m 2 .
  • the product comprises plus at least one central layer disposed between the two outer layers.
  • the outer layers have ridges on the surface, the spacing between the streaks of one of the layers being less than the spacing between the streaks of the other layer.
  • the invention also relates to a process for manufacturing a product of cotton wool according to the invention whose outer layers have on the surface streaks.
  • each outer layer is hydroliaged by means of water jets whose axes are spaced from each other 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 streaks on the surface with different spacing.
  • the product according to the invention consists of one hundred percent natural fibers of cotton and comprises at least two layers or tablecloths each having one side exterior.
  • the first layer consists of fine and soft fibers which have a low micronaire index.
  • the second layer on the contrary, consists of fibers of more cross section. large having a higher micronaire index and therefore having an effect scratching.
  • micronaire index is measured using a SHEFFIELD type device Micronaire according to a defined method, for example the ISO 2403 method or NF G 07-073.
  • This index is used to characterize the fineness of the cotton fibers. Its measurement is based on the air permeability of a cotton mass under certain specific conditions, on an arbitrary scale called a micron scale, calibrated using a series of cottons (ten standard cottons) to which indices have been assigned micronaires by international agreement.
  • a micron scale calibrated using a series of cottons (ten standard cottons) to which indices have been assigned micronaires by international agreement.
  • We measure the air permeability of a given sample taken from an outer layer of the product according to the invention (constituting the test specimen), by reading the resistance to the passage of the air flow on the air flow device, on a scale graduated according to variations in flow air or pressure differences. This scale has been previously calibrated with the reference cotton series.
  • the apparatus includes a balance for measuring the mass of the test tube, an air flow device for measuring the micronaire index, consisting of a perforated compression cylinder containing the test specimen and devices necessary for measuring the air permeability of the test piece, such as an air pump, means for adjusting the air flow or the pressure passing to through the test tube in the compression cylinder, a pressure gauge to read the pressure difference required and a flow meter for reading the air flow at across the test tube, and if necessary a scale graduated in index values micronaire or a table providing the conversion of readings into micronaire index. Sampling and sampling of samples is done for example in accordance with standards NF G 07-050 and NF G 07-062.
  • test piece is then determined.
  • test piece in the compression cylinder and one sets up the fiber compression piston, which is then locked.
  • finish air at the appropriate pressure or flow rate and note the pressure difference over the scale of the instrument.
  • the average of the readings obtained for all the test specimens is calculated taken from the same sample.
  • direct readings are converted to micronaire indices from the conversion curve.
  • micronaire index representing the average mass of fibers per unit of length is expressed in ⁇ g / inch.
  • the first layer of the product according to the invention consists of fibers of cotton with a micron index between 2 and 5 ⁇ g / inch, preferably between 2.8 and 4.2 ⁇ g / inch.
  • the second layer consists of cotton fibers having an index higher micronaire between 4 and 10 ⁇ g / inch, preferably between 5 and 8.5 ⁇ g / inch.
  • deci-tex is also a measure of the mass of a fiber or a thread per unit in length but which is a specific measure of artificial and synthetic fibers.

  • the increase in the grammage of each outer layer reinforces this differentiation by avoiding a reduction in the desired effect generated for example by the soft fibers of an outer layer in contact with the other outer layer made up of so-called scraping fibers and having a too light grammage or by a central layer of average micron index or by the soft fibers of a central layer placed just below an outer layer made up of so-called scraping fibers and having a too light grammage.
  • Figure 2 shows schematically in cross section a product 4 consisting of three layers of cotton.
  • the first outer layer 5 has a basis weight between 10 and 40 g / m 2 and has a low micron index.
  • the second outer layer 6 also has a grammage between 10 and 40 g / m 2 but has a high micron index.
  • the central layer 7 located between the two outer layers has a basis weight between 50 and 300 g / m 2 .
  • Figure 3 shows schematically in cross section another product 8 comprising three layers.
  • the first layer 9 has a grammage between 10 and 40 g / m 2 and has a low micronaire index while the second outer layer 10 has a grammage between 50 and 200 g / m 2 for a higher micronaire index.
  • the central layer 11 disposed between the two outer layers has a basis weight between 50 and 200 g / m 2 .
  • Figure 4 shows in cross section another variant of the product according to the invention.
  • This product 12 is composed of three layers, an outer layer 13 having a basis weight between 10 and 40 g / m 2 and a high micron index and another outer layer 14 having a basis weight between 50 and 200 g / m 2 and of low micronaire index, surrounding a central layer 15 having a grammage between 50 and 200 g / m 2 .
  • Figure 5 always shows in cross section a product 16 comprising four layers of cotton.
  • the first outer layer 17 has a low micron index and the second outer layer 18 has a high micron index, both having a basis weight between 10 and 40 g / m 2 .
  • the product further comprises two central layers 19 and 20 each having a basis weight between 50 and 200 g / m 2 , arranged between the two outer layers.
  • the process for manufacturing the products according to the invention consists in preparing at least two layers of cotton fibers forming the two outer layers of the product, one with a low micronaire index, the other with a higher micronaire index.
  • the difference between the micron indices of the two outer layers is at least equal to 1 ⁇ g / inch.
  • Tablecloths can be made directly from cotton hydrophilic and bleached. They can also be obtained from unbleached raw cotton, then chemically treated to obtain hydrophilicity and bleaching. After cotton tablecloths or tablecloths, the cotton tablecloths are superimposed and are then associated by any known means such as bonding means or means mechanical such as calendering or needling. The means of association can still be hydraulic.
  • a good association can be obtained by impregnating the tablecloths superimposed by any known conventional means such as passing through a bath impregnation, spraying, spilling a solution.
  • This impregnation must be associated with an expression compacting the water table and eliminating part of the quantity of liquid contained in the wet sheet for example by calendering or passage on a vacuum slot.
  • European patent N ° 0 681 621 in the name of the applicant. In the latter case, the impregnation of the layers carried out during the different chemical treatments, contribute to their association.
  • the sheets are combined by hydroletting, that is to say by means of high pressure water jets combined with vacuum expression.
  • hydroletting that is to say 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. This last technique allows both the association of the two plies between them and the bond of at least one surface of the ply thus reducing the fluffing of products.
  • This hydroliage step in the case of an unbleached fiber which will be treated chemically, can intervene just after the impregnation stage of the water table as this is described in European patent application No. 0 735 175. It can also be placed in the final rinsing phase according to European Patent No. 0 805 S88 in the name of the plaintiff.
  • Products in formats are then cut from the tablecloths thus associated by any conventional means.
  • One of the manufacturing advantages of the product according to the invention is its one hundred percent cotton fiber composition. Indeed, this allows to recycle easily waste from cutting using scraps for composition new products.
  • the user can differentiate the face soft from the most itchy side.
  • the composition of the first outer layer of cotton with low micron index will include an agent softener distributed mainly on the surface of this layer.
  • the hydroliage technique already used will be used to combine the tablecloths and avoid linting, to visually differentiate the two sides of the product.
  • the different layers are prepared, then superimposed; the whole is impregnated.
  • the two outer layers are then hydroliated one after another on endless canvases or cylinders.
  • the hydroliaging device includes a high pressure pump supplying an injector placed transversely to the running of the sheet or layer of fibers, over its entire width.
  • the injector consists of a volume of pressurized water, closed by a blade of steel which is perforated with calibrated holes producing jets in the form of fines high pressure water needles projected perpendicular to the surface of the water table fiber. These fine jets entangle the fibers.
  • the holes punched in this steel blade have a diameter ranging from 100 to 200 ⁇ m preferably 120 to 140 ⁇ m and are regularly spaced.
  • the distance between the axes of two consecutive holes of the steel blade is generally between 0.5 and 3 mm, the more often between 0.6 and 1 mm.
  • a hydroliage device whose blade is perforated with a significant distance between the holes from 1.2 to 3 mm, preferably from 1.6 to 2.5 mm, and for the other side, a device whose blade is perforated with a distance between the holes between 0.4 and 1.2 mm, preferably between 0.5 and 0.8 mm.
  • the streaks or grooves with a spacing of 1.2 to 3 mm will be more visible on the face as treated as the streaks on the other side.
  • This product 21 includes a first outer layer 22 with a micron index of 3.4 ⁇ g / inch and a basis weight of 25 g / m 2 , a second outer layer 23 with a micron index of 6.8 ⁇ g / inch and a grammage of 25 g / m 2 and a central layer 24 of 200 g / m 2 .
  • 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.
  • make-up and / or make-up removal The user is thus guided to discern the soft face from the more scratching the product in order to use each side of the product in its proper destination: make-up and / or make-up removal.
  • the increased distance between the holes in the perforated blade has as a direct consequence a reduction in the number of holes and therefore a contribution of lower energy on the water table which it is not always possible to compensate by an increase in the water pressure in the injector.
  • This decrease in energy transmitted to the tablecloth can cause an increase in lint compared to 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.
  • you can use a perforated blade with holes sequence for example groups of 6 holes spaced 0.6 mm apart, each group being spaced next 1.8 mm.
  • the pitch is important to around 4.8 mm.
  • the increase in linting is thus limited thanks to a average frequency of holes higher than that of a blade regularly perforated by example at a distance of 1.8 mm.
  • the average number number of holes per meter is 1250, whereas in the case of regularly spaced holes at a distance of 1.8 mm, this number is 555.
  • FIG. 7 illustrates a blade perforated with holes according to a sequence, here by group 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.
  • first outer layer which has ridges with a certain distance between 0.4 and 1.2 mm (here 0.6 mm) and a second outer layer which has streaks in a sequence comprising several 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).
  • the user thus has a cotton product whose two sides are distinguish, which retains its qualities of mechanical resistance, lint resistance, cohesion (resistance to delamination) and softness even if one side has an effect more scraping than the other for cleaning.
