Definitions

  • the present invention relates, on the one hand, to a method of finishing a sheet formed by the dry process, consisting of paper fibers linked by a thermoplastic binder such as a latex or hot-melt fibers, and the distribution of the fibers n is not homogeneous. And, on the other hand, the invention relates to tablecloths thus ennobled.
  • the product according to the invention comprising a pattern is used, after transformation, as a tablecloth, a napkin or other disposable decorative item.
  • This type of tablecloth is obtained by a well-known process which consists of treating paper pulp in order to defibrate it dry, forming a veil on a forming fabric where the individualized fibers are distributed randomly by air, providing a binder thermoplastic which will penetrate into the veil thus formed allowing the fibers to bond together, then to dry and crosslink.
  • Tablets of dry-laid cellulosic fibers consisting of a mattress of paper fibers distributed at random and of a thermoplastic binder, comprising a pattern on at least one face of the sheet. These plies have compressed and other uncompressed areas on their surface. The pattern can be obtained by embossing or marking the sheet.
  • embossed is understood here to mean creating on a part of a surface of the sheet, reliefs with corresponding depressions on the remaining surface of the sheet. In other words, the sheet which has been embossed has increased in thickness.
  • marking consists in compressing certain parts on one face of the sheet by forming compacted zones and by reducing the thickness of the sheet in these zones without forming relief on the opposite side.
  • the compressed or marked parts have a higher density than the parts which have not been compressed. Unmarked areas may or may not be calendared.
  • the marking of the tablecloth deposited in the dry state was used to improve the application of the binder on the sheet.
  • part of the sheet surface is compressed by cylindrical rollers before the bonding step, the pattern then being stabilized with the binder.
  • a surface of the sheet is marked by simultaneously applying a binder to the other surface of the sheet, thereby improving the penetration of the binder into the sheet.
  • the marking of the sheet is a step inside the process of manufacturing the sheet.
  • the dry-laid fibrous web is marked to increase its bulk and improve its absorption properties. At least 40 percent and preferably between 50 and 80 percent of the total area of one side of the sheet is marked. Both sides can be marked.
  • the method consists in marking the dry-laid sheet with a hollow pattern by means of cylindrical rollers which, preferably, are not resilient, these rollers being heated between 140 and 180 ° C and exerting sufficient pressure to densify the parts of the tablecloth located under the compressed areas and reach a density of between approximately 0.2 g / cm 3 and approximately 0.5 g / cm 3 .
  • the marking step is carried out here at any time after the deposition of the dry fibers on a mobile support and the consolidation of the sheet.
  • this type of product has strength properties, in particular breaking strength, which tend to decrease due to the shearing of the fibers.
  • Surface properties such as touch, softness are impaired.
  • the marking process used for this type of product and the size of the marked surface, that is to say, compacted areas, are probably at the origin of the decrease in these properties.
  • the product is less soft and less comfortable to use, which is detrimental in certain applications such as napkins.
  • the sheets have an uneven distribution of their fibers. Some parts of the web have clumps of fibers while other parts have clear areas with much less fiber.
  • a marking by means of a cylinder engraved in steel and a receiving cylinder also in steel, it can be seen that the areas of high grammage, "over-thickened", are well marked while the areas of low grammage do not are not or only slightly marked.
  • the areas of high grammage form "shims" between which the marking is weak. You cannot distribute the pressure evenly across the generator. The marking is therefore not regular.
  • the tablecloth thus marked does not have a uniform pattern and is of lower quality from an aesthetic point of view. This defect appears for the dry tablecloths, which notably have a grammage dispersion of plus or minus 20 percent.
  • the invention aims to overcome all the drawbacks mentioned above by providing a method of finishing the web which is a simple process of transforming the web, economical and flexible since the engraved cylinder can be easily changed. thus making it possible to modify the pattern marked on the tablecloth.
  • Another object of the invention is to provide a marked ply whose pattern is regular whatever the distribution of the fibers in the ply, while maintaining the mechanical properties of the ply and its surface properties.
  • the resistance properties of the ply are little modified.
  • the deformation imparted by the etching is permanent, which constitutes an undeniable advantage.
  • matt and shiny effects are given so that the sheet can present plays of light coming from the opposition of the hollows and the reliefs.
  • the hollow part corresponding to the compressed part, gives shine.
  • the thickness of the sheet decreases or not, compared to its initial thickness.
  • the invention relates to a particular method of marking a sheet formed by the dry process, consisting of paper fibers linked by a thermoplastic binder such as a latex or thermoplastic fibers, and the distribution of fibers n is not perfectly homogeneous, using a marking technique known in the textile field to ennoble fabrics; it is the embossing of fabrics.
  • the method consists in deforming under heat stress the web between a hard, non-deformable engraved cylinder and a receiving cylinder with a hardness of between approximately 60 and approximately 95 degrees Shore D, resilient and deformable under the pressure exerted by said engraved cylinder.
  • the resilience of the receiving cylinder is defined here by the ratio between the energy returned by the cylinder after deformation and the energy which had been supplied to it to deform it. This ratio can be determined from the hysteresis cycles obtained by successive traction and relaxation using a dynamometer or by subjecting a test piece to an impact using a pendulum.
  • the receiving cylinder is made of a material which can undergo deformations, such as a paper, rubber, polyamide, polyurethane or even textile material.
  • the engraved cylinder is made of steel and is heated to a temperature ranging from approximately 80 to approximately 180 ° C and preferably from approximately 130 to approximately 150 ° C.
  • the subject of the invention is also a sheet formed by the dry route, consisting of paper fibers linked by a thermoplastic material, the distribution of the fibers of which is not perfectly homogeneous, having a formation index less than about 75 measured on a KAJAANI device. in the rough, and comprising on at least one of its faces a marked pattern.
  • the rate of marking of the surface of the tablecloth comprising the marked pattern is greater than about 80 percent.
  • the marked area of the sheet is less than 40 percent of the total area.
  • the subject of the invention is also a sheet obtained according to the method according to the invention, characterized by its marked surface, which is greater than 40 percent of the total surface.
  • the problem posed in the present invention comes from the fact that the tablecloth intended to be ennobled consists of free linked paper mills which are not distributed in a uniform or homogeneous manner in the tablecloth. In fact, the density varies within the same tablecloth more or less significantly.
  • the distribution of the fibers in the sheet, before marking and before coloring, will be described below by the air or formation index which is an index measuring the regularity of the arrangement of the fibers in the thickness of the sheet.
  • the visual aspect of the product seen by transparency gives a qualitative measure of the look.
  • the training index can be quantitatively measured by optical means.
  • the formation index is measured in the following way: light is passed through the sheet and the intensity of the light transmitted through this sheet is measured. This measurement is carried out on an appropriate device, here a training analyzer marketed under the name KAJAANI, a fully automated optical device.
  • the uniformity or regularity of the distribution of the fibers is determined by measuring the variation in the intensity of the light transmitted through a sample. The area of the measured sample is 63.5 millimeters by 63.5 millimeters.
  • the analyzer captures the image of the sample, divides it into pixels and stores it in memory. Each pixel is then resolved into 256 discrete levels of gray.
  • the computer statistically calculates a histogram and the formation index of the measured sample.
  • the training index varies in a scale from 20 to 122.4; a higher value corresponds to better, more uniform training. The most uniform formation (measured without sample) is 122.4.
  • the measurement of the formation index is carried out on sheets in the raw state, that is to say white sheets corresponding to the sheets before coloring and before marking.
  • the plies used in the process according to the invention have a formation index of less than around 75.
  • a well-formed web can have a grammage variation of ⁇ 4 grams.
  • the binder is essentially latex and, in general, an emulsion of the ethylene-vinyl-acetate type, or else powders or hot-melt fibers.
  • these plies are already bonded, that is to say consolidated by the thermoplastic binder, dried and crosslinked.
  • the process according to the invention takes place outside the process for manufacturing the web itself or at the end of the latter, unlike most of the processes of the prior art where the marking step takes place after the deposition of dry fibers and before the binding operation has been completed.
  • the method according to the invention consists in deforming under heat stress the sheet to permanently mark a decorative pattern on at least one of its faces.
  • the stress deformation step and the heating step can be simultaneous or dissociated depending on the nature of the engraved cylinder.
  • the latter is made of a hard, non-deformable material.
  • this cylinder is made of engraved steel.
  • the steel cylinder is directly heated.
  • the heating step would be dissociated from that of compression as has already been proposed for the embossing of textiles.
  • the pattern is engraved on the hard, non-deformable cylinder.
  • the surface of the cylinder is more or less engraved depending on the type of ply desired.
  • the pattern engraved on the surface of the cylinder has parts in relief which correspond to the parts marked in hollow on the surface of the sheet.
  • a maximum of 40 percent of the surface of the cylinder is etched and preferably between approximately 10 and approximately 40 percent and even more preferably between approximately 15 and approximately 30 percent.
  • the engraving pattern in this case, is quite decorative.
  • the drawing can be, for example, made up of several unitary patterns such as a flower or the like, or of thickened lines or lines giving a marbled effect etc.
  • the height d of the part 1 in relief on the engraved cylinder 2 or even the depth of the engraving must be strictly greater than the thickness e of the sheet or of the sheet 3 which is intended to be marked so that the surface 4 of the sheet which is not marked, that is to say which is not deformed by the part 1 in relief of the engraved cylinder 2, is not in contact with the part 5 without relief of the engraved cylinder 2 which, moreover, is heated in the general case. Therefore, the thickness of the initial ply is not changed significantly.
  • a second type of ply For a second type of ply, more than 40 percent and preferably between 60 and 90 percent of the surface of the cylinder is engraved.
  • the pattern is then much smaller and can be in the form of multiple dots: In the latter case, the marking gives an overall appearance of textile weft to the tablecloth. Indeed, for this type of tablecloth, we are looking for a textile look and feel of the finished textile type such as starch cotton, that is to say a hand print of fabrics. We also aim to obtain a sheet of constant thickness and less than the initial thickness, always in the spirit of having a product of textile appearance or imitation.
  • the depth of the etching is, for the second type of sheet, less than the thickness of the sheet. Consequently, with in addition a large marked surface, the sheet decreases substantially in thickness.
  • the receiving cylinder also known as a counter-cylinder is made of a resilient or "elastic" material, as defined above, and can undergo deformations when the engraved cylinder exerts stresses.
  • the material used for this receiving cylinder should have a hardness in the range of about 60 to about 95 degrees Shore D.
  • the hardness of this material will be in the range from about 65 to about 85 degrees Shore D.
  • the material used are rubber having for example a hardness of about 88 Shore D degrees for the rubber marketed under the Polylay brand, the paper having for example a hardness of about 78 to about 82 Shore D degrees, the polyamide having a hardness of about 80 degrees Shore D or a textile material having a hardness from about 78 to about 85 degrees Shore D.
  • the cylinder of textile material gives good results. It is possible to envisage a cylinder made of "composite" material where the core of the cylinder is made of paper and the coating of the cylinder is made of textile material, for example of woolly type. The hardness of such a cylinder is approximately 82 degrees Shore D.
  • Polyamide is also very suitable allowing good distribution of the force over the entire surface of the cylinder and matching the surface of the patterns. Any equivalent elastic plastic material can be considered.
  • the receiving cylinder or counter-cylinder is flexible and accepts irregularities in the thickness of the ply. It advantageously deforms along the contour of the protruding parts of the engraved cylinder when the latter is applied under pressure and hot to the ply intended to be marked.
  • the ply is hot stamped between the engraved steel cylinder which is heated, and the receiving cylinder or counter-cylinder.
  • the engraved cylinder is heated to a temperature equivalent to the softening or creep temperature of the material constituting the sheet in the compressed zone, that is to say to a temperature between approximately 80 and 180 ° C. and preferably between approximately 130 and 150 ° C.
  • the engraved cylinder exerts a linear pressure on the web, which can vary in a range ranging from approximately 40 to approximately 150 kg / cm and preferably from approximately 60 to approximately 100 kg / cm.
  • the machine can have a speed of about 10 to about 300 m / min. and preferably about 80 to 200 m / min.
  • the temperature increases with the speed of the machine.
  • the pressure and the temperature of the engraved cylinder must be correlated.
  • the tablecloth resulting from this process is marked.
  • the marked areas are compacted and their density has increased.
  • the grammage of the marked ply varies little compared to that of the initial ply.
  • the marked pattern is very regular and permanent.
  • the marked surface of the tablecloth is less than 40 percent of the total surface of the tablecloth, in contrast to the tablecloth marked using the method described in European Patent No. 0 077 055 of the art prior.
  • this marked area varies in the range from about 15 to about 30 percent of the total area of the web. This limitation of the marked area is essential for this type of sheet.
  • the average thickness of the sheet thus marked has decreased very little in the range of 0.02 to 0.2 mm and preferably less than 0.1 mm compared to the initial thickness.
  • the web advantageously retains the surface properties before marking, such as its soft feel and its softness.
  • the tablecloth thus marked has greater softness than tablecloths marked in a conventional manner.
  • One of the essential characteristics of the marked ply according to the invention resides in the fact that it has a permanent pattern despite the heterogeneity in the distribution of the fibers of the ply, illustrated by the air.
  • This characteristic can be quantified by measuring the rate of marking of the web.
  • the marking rate corresponds to the transfer efficiency of the engraving image of the cylinder engraved on the web. This marking rate was measured by image analysis on a device sold under the name Quantimet 600 by the company LEICA.
  • the method of analysis consists in subjecting samples of the tablecloth to grazing lighting at a certain angle, thus highlighting the relief of the pattern by creating areas of shadow.
  • the area of the shaded areas is measured from a gray threshold determined from a control.
  • the marking rate is the following ratio: marked surface of the sheet (relative to the total surface of the sheet) on theoretical marked surface (corresponding to the engraved surface of the cylinder) relative to the total surface of the sheet.
  • a marking rate of 0 percent corresponds to an area that has not been marked and a marking rate of 100 percent corresponds to an ideal or perfect marking.
  • the 100 percent marking rate is in fact the perfect imprint of the relief of the engraved cylinder.
  • the tablecloth marked according to the invention corresponding to the first type of tablecloth, that is to say the tablecloth whose marked surface is less than 40 percent, has a labeling rate greater than about 80 percent and preferably more than 90 percent.
  • Another advantageous characteristic of the first type of ply is that it has shiny surface parts alternating with dull surface parts, clearly visible to the naked eye, the shiny parts corresponding to the marked surface of the ply. This matt and shiny effect brings out the motif clearly and contributes to the refinement of the tablecloth. It gives a satin appearance to the marked surface part and recalls, in terms of touch and appearance, damask cotton.
  • the marked surface is greater than 40 percent of the total surface of the tablecloth.
  • the sheet has a lower apparent thickness compared to its initial thickness. The reduction in thickness is around 25 percent of the initial thickness. This ply also has the advantage of having a constant thickness which is not always the case with the initial ply at the end of its manufacture.
  • the rigidity can be advantageously increased so that, for example, the napkins can have a touch of finished textile and, once folded for presentation, keep this shape folded. To do this, the grammage of the sheet is increased and an appropriate binder is chosen.
  • the marked ply according to the invention whatever its marked surface, has mechanical properties, in particular resistance properties, substantially identical to those of the ply before treatment.
