Definitions

  • the present invention relates to absorbent paper products, more particularly cellulose wadding, sanitary or domestic use and aims a sheet consisting of at least two plies, one of which is embossed, intended for the realization of toilet paper essentially, but also handkerchiefs or towels.
  • the present invention relates to paper transformed from a dried paper sheet which has been pre-made in a wet phase on the paper machine.
  • the most widespread embossing patterns consist of a repetition on a geometric frame of elementary protuberances of small cross section and simple geometric shape.
  • An example is described in the patent US 3,414,459 which relates to a sheet with two or three plies, ie consisting of a plurality of elementary sheets, called folds, bound or glued together.
  • the plies are embossed with a frequency of distribution of the protuberances and a height of the protuberances adapted to the production of water-absorbing products such as paper towels, the number of elements ranging from 3 to 30 protuberances cm 2 .
  • the embossed folds are associated according to a so-called "tip-tip" process, in which the vertices of the protuberances of one fold face the tops of the protuberances of the other fold.
  • the Applicant has developed, for toilet paper in particular, patterns whose number of elements is greater, ranging from 30 to 100 protuberances per cm 2 . In this case, because of their number, these elements form protuberances of lower height and necessarily have an elementary surface at the top also very low, less than 1 mm 2 . For these last embodiments, an aspect is obtained which mimics that of a woven product.
  • An example has been described in the patent EP 0 426 548 B1 . This type of embossing mainly affects the mechanical characteristics of the sheet such as its rigidity and strength.
  • absorbent paper products consist of two plies but obtained according to a different association technique.
  • a fold or a set of two superposed folds is waffled and, on the other hand, a second fold by means of two distinct embossing devices.
  • the first fold and the second fold are embossed in relief patterns consisting of protuberances.
  • the density of patterns necessarily remains low: less than 20 protuberances per cm 2 for this type of product.
  • the two plies are associated by means of a marrying cylinder so that the distal surfaces of the protuberances of the two superimposed folds are disposed opposite the surfaces located between two protuberances in the plane of the second fold. This technique is still called “nested" process.
  • the Applicant has also developed a product consisting of two plies, one embossed, the other unembossed.
  • Each fold has a basis weight of the order of 10 to 40 g / m 2 .
  • One is embossed with relief patterns consisting at least in part of discrete protuberances facing the inside of the sheet and the other is unembossed.
  • the embossed fold has on at least a portion of its surface at least 30 protuberances per cm 2 , the top surface of which is less than 1 mm 2 , preferably less than 0.7 mm 2 .
  • the fibrous and / or chemical composition of the plies may be the same or different.
  • the unembossed ply may have a fibrous composition essentially based on long fibers such as softwood fibers, and the embossed ply a fibrous composition essentially based on short fibers.
  • the non-embossed ply may include a wet-resistant additive, and the embossed ply may include a softening or debonding additive.
  • the sheet thus composed has a very good wet strength and therefore good strength, in particular due to the composition of the non-embossed ply. It also offers a softness of surface by the choice of the fibrous and chemical composition of the embossed fold.
  • the sheet also has remarkably, substantially the same thickness as a double sheet made with two embossed plies in the same way as the embossed ply and assembled in point-to-tip position.
  • a first embossing roll 10 with a rigid coating, has on the surface spikes of a shape adapted to the production of desired protuberances. These pins are generally obtained by etching the cylinder.
  • the process for producing the sheet consists in embossing a first ply of cellulose wadding 20, unwound from a spool, between the embossing roll and a roll 12 made of rubber or other equivalent material, and then assembling it by means of a marrying roll 14 to a ply of non-embossed cellulose wadding 40, also unwound from a mother reel.
  • the marrying roll applies the fold 40 to the first fold 20 while the latter is still in contact with the embossing roll 10.
  • a water-based adhesive substance was applied, if appropriate, to the tops of the highest embossed protuberances. first ply 20 by means of a gluing roll 16.
  • the sheet from the machine is rolled into logs of small diameter corresponding to that of the rolls that will be marketed; then the logs are cut into the said rolls.
  • the embossed fold is the so-called outer fold of the sheet when it is rolled up and the non-embossed fold the so-called inner fold. It is sought thereby to make the embossing visible, preferably.
  • a marrying cylinder whose coating is hard but rubber anyway.
  • This deformation of the surface of the marrying roll leads to a deformation of the sheet at the point where the contact pressure is high, ie the zone of the connecting pins.
  • These protuberances are of low height but it is sufficient for them to be perceived to the touch, providing an unpleasant sensation affecting the softness of the product. This is an undesired side effect.
  • the engraving pattern of the embossing cylinder of the figure 3 is composed of frustoconical or truncated pyramidal pins, the first ones being aligned and the second ones being surface-filled.
  • the first can be raised by 0.2 mm for example compared to the second.
  • the protuberances formed from these first spikes receive the bonding adhesive of the embossed ply with the non-embossed ply. Due to the pressure of the marrying cylinder exerted on the sheet, the inner ply is deformed by these first protuberances while one would wish smooth.
  • the plies consist of cellulose wadding with different fibrous or chemical compositions
  • CWP Conventional Wet Press
  • This technique consists in forming a sheet by depositing a paste consisting of fibers suspended in water on a forming fabric, draining it, and wringing it by transferring it with pressing to a second fabric. felt, then to apply it to a large diameter drying cylinder from which it is detached after drying by means of a doctor blade.
  • the scraping is performed so as to form a crimp of fine close and regular undulations, imparting volume and elongation to the dried sheet.
  • creping in the case of a sheet with an embossed fold and a non-embossed fold bonded together, the back-side effect can not be avoided.
  • the Applicant has set itself the objective of producing such a product that is to say comprising a first and a second ply of cellulose wadding, the first of which is embossed with relief patterns, consisting at least in part first protuberances oriented towards the inside of the sheet, and the second is unembossed, the two plies being bonded by bonding of the first protuberances, which does not have the disadvantage of the prior art.
  • the invention therefore relates to products whose nature of the protuberances of the embossed fold is likely to generate a backside effect.
  • These are protuberances whose cross section in the plane of the fold is truncated cone or pyramid trunk.
  • These protuberances are insulated or arranged side by side along the same line or portion of line, curved or rectilinear, that is to say arranged in a single row.
  • the reason for the figure 3 is an example.
  • protuberances whose cross section in the plane of the fold is elongated. These protuberances are linear and form lines or portions of continuous line.
  • protuberances are designated by protuberances arranged in a single line.
  • the roller according to the invention is made by winding a sheet of absorbent paper for sanitary or domestic use comprising a first and a second ply of cellulose wadding, the first ply being embossed with patterns in relief, consisting at least partly of premieres protuberances facing the inside of the sheet, the second fold of the throughdried type, of thickness between 0.2 and 0.5 mm for a basis weight between 15 and 45 g / m 2 , not being embossed and being bonded to the first ply by bonding said first protuberances, characterized in that said first protuberances are insulated or arranged in a single row so as to form a single line and that the embossed fold forms the outer fold of the sheet and the non-embossed fold forms the inner fold
  • the thickness is an average measurement performed on a stack of 12 folds: a 10 cm 2 surface probe is placed on the folds with a descent speed of 2 mm / s, then applies a pressure of 20 g / cm 2 ; after a duration of 5 seconds, the value of the thickness is measured (according to EN 12625-3).
  • a paper of the air-blown dry type which will be referred to as TAD, is in itself known. It differs from CWP type paper by first drying the sheet downstream of its formation and before any compression. This drying is carried out while the still wet sheet rests on a canvas, by hot air directed through it.
  • the thickness of the second fold is between 0.2 and 0.3 mm.
  • said first protuberances cover between 2 and 15% and more particularly between 2 and 10% of the surface of the sheet.
  • the invention is preferably applied to a sheet whose first ply further comprises second protuberances with a density of between 30 and 100 protuberances per cm 2 , the first protuberances being at a minimum higher level than the second protuberances with respect to the plane of the first fold.
  • the first fold is a fold of the CWP type.
  • the sheet consists of the first and second plies mentioned above.
  • the hybrid sheet will be referred to as a sheet comprising an embossed ply and a non-embossed type TAD ply.
  • the product from the machine illustrated on the figure 1 comprises a first ply of cellulose wadding 20, which has been embossed on the embossing roll 10 associated with a second ply of cellulose wadding 40 which has not been embossed.
  • the fold 20 comprises in this example first protuberances 20 1 and second protuberances 20 2 .
  • the fold 40 is connected to the fold 20 by the protuberances 20 1 which correspond to the first pins 10 1 of the cylinder which are prominent with respect to the second pins 10 2 . Due to the pressure exerted by the marrying cylinder, given the speed of manufacture imposed by industrial constraints, it can not be avoided that the sheet 40 is deformed to a certain extent.
  • the adjustment of the pressure applied by the marrying cylinder results from a balance.
  • the glue applied to the tops of the protuberances 20 1 forms a connection between the two folds 20 and 40 only if a minimum pressure is exerted by the marrying cylinder. Too low a pressure would lead to a leaf with unassociated areas. Too much pressure leads to a leaf having a very pronounced backside effect. In manufacturing, we always seek a compromise. To obtain a bound product, the difference between the levels of the vertices of the first and second pins is generally at least 0.2 mm. If a product is produced with an engraved cylinder whose pins are all the same height, this is at least 0.4 mm.
  • This back-up effect springs up when the sheet is rolled up while it is being rolled.
  • a mandrel or a spindle is used which is rotated about its axis. This rotation involves a pull on the sheet and a tightening of the latter on the roll. This results in a pressure of a turn on the underlying turn and the protuberances of the outer fold of the coil support on the inner fold.
  • the underlying coil is flexible, it does not constitute sufficient support for the force of the protuberance on the inner fold, it is deformed producing a relief on the opposite smooth face.
  • the backside effect is springing.
  • the solution of the invention to avoid precisely the deformation during the winding has been to replace the smooth fold CWP type so far, by a fold of the air-drying drying type, TAD.
  • the manufacture of this type of TAD of cellulose wadding is described below.
  • the pulp consisting of fibers suspended in water is deposited in one or more jets on a moving web known as forming the sheet.
  • the sheet is transferred to a fabric having a large porosity and a determined relief.
  • This fabric is driven on drying means by hot air passing through, for example in the form of a cylinder around which the fabric with its sheet is guided. During its passage on the cylinder the sheet is crossed by a mass of hot air which greatly increases its dryness freezing the fibrous structure of the sheet. This structure depends on the imprint left on the sheet by the canvas.
  • a marker fabric is preferably used which comprises a weaving structure with zones of high porosity and areas of low porosity disposed according to a geometric definition determined such that it induces in the sheet a heterogeneous structure having areas of different compaction by the very effect of the air through.
  • Drying can be carried out on a single means of drying by passing air or by step on two means, one after the other.
  • the sheet may retain a certain degree of residual moisture and be applied to a drying cylinder, Yankee type known per se, to complete its drying so as to allow its creping by delamination by means of a scraper blade.
  • Other means than conventional creping are known to impart elongation to the sheet.
  • the invention is not limited to the use of a fold of cellulose wadding dried according to a particular technique of passing air blowing. Any other technique equivalent to the scope of those skilled in the art can be implemented. This manufacturing technique allows the production of sheets whose mass volume is higher than for CWP sheets. At equal weight the sheet is therefore thicker.
  • a TAD-type ply with a basis weight of between 15 and 45 g / m 2 and a thickness of between 0.2 and 0.5 mm, preferably between 0 and , 2 and 0.3 mm.
  • the fiber composition is a mixture of long fibers of wood pulp, such as softwood and short wood pulp fibers, such as hardwoods.
  • the first embossed fold is a fold CWP.
  • the thickness of such a fold is between 0.1 mm and 0.15 mm.
  • FIG. figure 3 This is a pattern consisting of first protuberances, relatively large and drawing an aesthetic pattern, and second protuberances finer, density of 80 protrusions per cm 2 , forming a filling within the design of the first protuberances.
  • a CWP cellulose wadding web of fibrous composition 40% SWK premium long fiber pulp of Canadian origin obtained by cooking kraft / 60% Eucalyptus, with a crepe rate of 20% (crepe ratio of the speed difference between the dryer cylinder and the winder on the speed of the dryer), Weight: 20,5 +/- 0,5 g / m 2 , Thickness: 1.84 mm for 12 folds.
  • a hybrid sheet according to the invention was made, the ply CWP of which was embossed from the CWP strip according to the pattern of the figure 3 and the non-embossed fold was a TAD fold consisting of the TAD tape and a control sheet whose embossed fold was identical to that of the sheet according to the invention (CWP fold) and the non-embossed fold consisted of the CWP tape.
  • the operating conditions on the machine of the figure 1 were the same in both cases.
  • the sheet in both cases was placed in rolls of diameters 10 cm. These are rolls of toilet paper made in a conventional way.
  • the method of manufacture is as follows. At the exit of the machine like that of the figure 1 where the folds are assembled, the sheet is driven to a winding station in logs. The logs are rolls of diameters of 10 cm here and of width equal to that of the sheet. The leading edge of the sheet is glued to the cardboard mandrel or spindle, and the mandrel rotated about its axis; some traction is exerted on the sheet and ensures tightening. It is during this winding with tightening, even moderate, that the reverse effect is revealed. Once the log is finished, it is routed to a sawing station in rolls of toilet paper. There are 26 of 10 cm long for an original sheet of 260 cm.
  • the samples are placed on the reverse side facing the 3D analyzer lighting to study the internal fold of the sheet. Each sample is flattened as best as possible to avoid measuring differences in parasitic heights.
  • the analyzed surface is a rectangle of 20X16 mm. The surface is illuminated by a projection of bright fringes. The fringes are obtained by a light passing through various calibrated grids. The image is acquired by triangulation between the fringe projector, the sheet and the camera. The camera allows you to save images to a computer's memory via the Optocat program.
  • the images are then processed by the Toposurf software.
  • the image is first flattened to compensate for optical distortions due to the lens of the camera and then clipped to remove extreme values (99.9% of the data is retained).
  • a reference image is then obtained. Each pixel of the image is referenced in space and has ribs along the three axes.
  • Reference images are then processed by the 'Morphology / z cuts' function.
  • This function makes it possible to make cross sections perpendicular to the z axis and to calculate with respect to a horizontal plane of altitude z the surface of the points situated above or below the plane.
  • This function was used by varying the Z value to compare products.
  • the images were analyzed using the software mentioned above. Images were cut along the z-axis keeping only the pixels present above a given threshold.
  • the threshold was increased progressively until most of the pixels corresponding to the crepe disappeared. The remaining pixels thus correspond to the upside effect at the first protuberances.
  • a curve has also been plotted for each threshold on the abscissa of the ratio of the area below the threshold with respect to the total area. This curve, referenced A, is reported on the figure 7 . Knowing that the surface of the first protuberances covers in this example 5 to 8% of the total surface, the threshold measured is then 0.05 mm. It remains then a height of 0.05 mm for the protuberances which are at the origin of the effect of back.
  • Curves A and B make it possible to deduce that the hybrid sheet produced according to the invention with an embossed CWP ply and an unembossed TAD ply has a threshold of 0.07 mm, which corresponds to a height of only 0.03 mm for protuberances likely to generate a backside effect. This reduction of 40% of the height of the protuberances is enough to remove the perceived upside effect.
  • the first protuberances are not of point form but they consist of linear elements.
  • the graph of the figure 7 shows that the behavior is the same as for the present invention on discrete protuberances.
  • the profile of this curve is close to that of curve A.
  • the unpleasant perception of the upside-down effect is no longer present on the hybrid sheet according to the invention, in particular after winding the sheet. As a result, the perceived overall sweetness of the product by the consumer is improved.
