Definitions

  • the present invention relates to machines for producing patterned nonwoven textile products and nonwovens produced by such machines.
  • the WO 03/008691 a relief marking roll of a nonwoven is described.
  • the device used is such that it is impossible to create closed contours without using metal bridges linking the inside to the outside of the contour. It necessarily follows patterns delimited by discontinuous features.
  • the invention proposes, on the other hand, to obtain on a nonwoven a pattern delimited by a continuous contour.
  • the US 5,115,544 patterns are produced on a nonwoven by passing the nonwoven over a drum and projecting jets of water onto the nonwoven as it passes over the drum.
  • Two cases are provided to produce recessed patterns on the nonwoven.
  • the fineness of the lines of the drawing is limited for its minimum by the deformation properties of the nonwoven embossed and limited for its maximum by the fact that one can not have a large surface embossed "in the air" without support mechanical.
  • EP 0 776 391 a random microperforated roll is described.
  • EP 1327712 , EP 0215684 and WO2006 / 051191 describe drums for entanglement machine by water jets
  • the invention overcomes these disadvantages while solving a different problem. It makes it possible to obtain a non-woven having little hairiness both in the projecting parts and in the recessed parts delimiting the pattern, which may be of continuous contours and have a dimension greater than 2 mm. It is thus possible to create patterns delimited by a line drawn deliberately, but also patterns that are not delimited by a line drawn by a furrow or a rib, but which are in the form of a "monoblock", entirely in protrusion or all hollowed out delimiting itself.
  • the subject of the invention is a drum as defined in claim 1.
  • the drum of the invention has an open surface (small opening ratio). This characteristic makes the product of the invention has a low hairiness.
  • the drum makes it possible to generate bonding at the same time as marking.
  • the ends of free fibers (pilosity) are limited in number because they are integrated in the fibrous mass (fibers bonded together).
  • Existing marking technologies have a large, open, non-binding surface, which increases pilosity during marking.
  • the drum is made of nickel.
  • the numbers of the perforations, both in the at least one first zone and in the at least one second zone, are preferably between 80 and 130 cm 2 .
  • the formation of patterns can be done effectively only by precise management of the water flow from its emission to its suction through the patterning drum. This particularly important water flow management in the case of wetlaid products where the fibers are very short and therefore more mobile is controlled through the distribution and the size of the perforations.
  • these perforations In order to obtain a good marking without creating a perforation in the nonwoven, these perforations have a dimension between 0.1 and 1, 2 mm and the density of these perforations must be between 40 and 200 / cm 2 .
  • the drainage flow rate is locally insufficient, which can cause perforations caused by excessive displacement of the fibers.
  • the open surface is too large to retain the fibers that will be entrained and sucked with the water, thus creating uncontrolled perforations in the non-woven.
  • the through perforations have a dimension of preferably between 0.3 and 0.8 mm.
  • the size of a perforation is the diameter of the circle circumscribing a perforation.
  • the perforation may have any shape and in particular circular, rectangular, elliptical.
  • the perforations are preferably randomly distributed to the side surface of the cylinder.
  • the surface of each perforation may be between 0.008 and 1.5 mm 2 .
  • the opening ratio is 3 to 60%, and preferably 5 to 15%, this percentage representing the perforated area relative to the total lateral surface of the roll.
  • the perforations are cylindrical having preferably a circular cross section, although they may also have a square section or the like.
  • the area taken by a perforation on the outer lateral surface of the cylinder is thus equal to the area taken by this perforation on the inner lateral surface of the cylinder.
  • the first layer has a thickness of between 0.3 and 2 mm and the second layer has a thickness between 0.3 and 2 mm.
  • the smallest imaginary inscribed circle traced on the outside face of the lateral surface of the cylinder, both in the at least one first zone and in the at least one second zone, has a diameter greater than 0.5 mm, preferably greater than 2 mm.
  • a first zone is in the form of a hammer, it means that the smallest circle inscribed is that which corresponds to the handle of the hammer and not to a circle inscribed in the head of the hammer.
  • the variation in height of the outer surface of a zone and, preferably, of all the zones of the lateral wall is less than 0.05 and better still 0.01 mm. This is in direct contradiction with the teaching of EP 0 705 932B . This makes it possible to obtain a less aggressive surface with respect to the fibers favoring hydrolysis, which gives the nonwoven a more regular appearance.
  • a level is defined by the points at the same radial distance from the drum axis. All the points of the same level are on the lateral face of the same cylinder of a given diameter. The heights of the outer surface of a zone are defined in the same way.
  • the height variation is measured according to ISO 4287 where it is indicated by the notation zt.
  • the probe instrument of the Federal Office of Metrology METAS is used.
  • the measuring instrument is a probe instrument with a precise reference translation unit.
  • the movement of the probe arm is measured interferometrically.
  • the vertical resolution is 10 nm at each measurement point.
  • the resolution of the horizontal displacement is 0.25 ⁇ m.
  • the measuring range for profile evaluation is 120 mm (horizontal) and 6 mm (vertical).
  • the diamond tip of the probe usually has a radius of 2 ⁇ m at its end and an angle at the apex of 90 °.
  • the probe instrument is directly attached to the base meter unit by means of a reference standard.
  • the drum according to the invention makes it possible to reduce the frequency of cleaning by limiting the stitching of the short fibers onto the surface of the cylinder, particularly in the case of use on wetlaid products, which is very sensitive to this phenomenon and to reduce the loss of fibers. short when used, especially on wetlaid products.
  • the perforated marking drum can be manufactured in two stages.
  • a first step an electrolytic deposit of nickel on a conductive matrix is performed by the screen printing technique.
  • a photographic film showing the pattern of perforations background is realized.
  • This film is then placed on a matrix having exactly the inside diameter of the perforated cylinder.
  • This matrix is previously coated with a photosensitive layer. After exposure to light radiation, the matrix is rinsed. Only coated areas not exposed to radiation remain on the matrix. This is then immersed in an electrolysis bath.
  • the nickel is deposited on the areas not coated with a photosensitive layer. After about eight hours, the deposit has reached its optimum thickness.
  • the cylinder is demolded.
  • the cylinder is coated, again, with a photosensitive layer.
  • a new film representing the marking pattern is placed on the cylinder.
  • the cylinder is rinsed. Only areas not exposed to the radiation of the coated layer remain on the cylinder. It is immersed in an electrolysis bath. The nickel is deposited on the cylinder previously produced on the areas not covered with a photosensitive layer. Nickel does not fill the perforations of the lower cylinder. The perforations thus extend to the new nickel deposit. After about ten hours, the new deposit has reached its optimum thickness. The cylinder is then removed from the bath and freed of photosensitive layer residues.
  • the subject of the invention is also a machine for manufacturing a patterned nonwoven comprising an injector of water jets on the outer face of the lateral surface of a cylinder according to the invention and means for passing an web without patterns between the cylinder and the injector. At the outlet of the cylinder, the nonwoven web is provided with a conjugate pattern of the cylinder pattern.
  • the nonwovens may be made of natural or artificial or synthetic fibers.
  • the nonwovens are generally obtained by the carding or aerodynamic technique, they can also consist of continuous thermoplastic filaments obtained by the so-called spunbond technique, or even meltblowns.
  • the nonwovens can also be obtained by the so-called wet technique, they can also be obtained by the combination of several processes such as, for example, spunbond plus carded veils, spunbond plus natures deposited aerodynamically by airlaid and linked by jets. of water. Good results have been obtained with nonwovens of 30 to 150 g / m 2 based on viscose, viscose / polyester and cotton blends. But this list is not exhaustive.
  • the thicknesses of the nonwovens, including the protruding patterns, are generally between 0.5 mm and 2.5 mm and the elevation of the protruding parts is preferably between 0.3 and 2.0 mm, preferably between 0.5 and 1.5 mm.
  • the thickness of the elevation is measured in the following manner: the thickness is measured by placing the nonwoven in a non-woven thickness measuring apparatus, as recommended by the EDANA ERT 30.5-99 standard. The elevation is measured with a magnifying glass of magnification eight times and micrometric scale. A magnifying glass with a magnification of eight times is also used to determine the distance from which the free ends of the filiform filaments project and their number.
  • the non-wovens may be subjected to a first bonding treatment on a conventional machine for bonding the nonwovens by water jets and immediately after the continuous transfer to the machine that is the subject of the present invention.

  • the hairiness of the nonwoven, marked with the new drum, is lower than in the case of the prior art. This is explained by the fact that the new drum has a bonding surface promoting integration of the ends of fibers in the fibrous mass.

  • the dimension of the pattern according to the face as defined by the smallest imaginary inscribed circle, may be greater than 2 mm and the pattern may have a uniform depth of 0.3 to 2 mm, preferably 0.5 to 1, 5 mm.
  • This possibility of having a dimension of the pattern according to the face, therefore a radius of the pattern if it is circular or a length of the pattern if it is rectangular, greater than 2 mm makes it possible to obtain not only patterns delimited by lines. but also a pattern which is not delimited by lines, the pattern being formed by the same unevenness printed on the nonwoven and not only by lines of contours printed on the nonwoven.
