Definitions

  • the present invention relates to the preparation of paper for filter bags.
  • filter sachets means infusion sachets, in particular tea or medicinal plant sachets, and coffee or similar sachets.
  • sachet includes the packages delivered in a closed state and filled to the user, as well as the sachets delivered open, for example in the form of a cone, and filled by the consumer, before use.
  • bag is not limited to a particular geometry. It includes, for example, generally cylindrical packaging obtained in the case of products packaged in a compressed state, for example in the case of coffee sachets.
  • the present invention relates more precisely to the preparation of paper for filter bags, of the type formed by a nonwoven structure composed of a layer based on synthetic fibers and a layer of superimposed cellulosic fibers, and having a particular apparent texture, or a repeating pattern such as, for example, a semi-perforation at regular intervals.
  • the texturing operation by fluid jets is most often carried out by projecting the fluid jets 20 onto the paper 12 through a rotary perforated cylinder 22 or a movable perforated strip 120. During this operation, the paper 12 must of course be supported by support means which have not been shown in FIG. 1 to simplify the illustration.
  • the fluid used is generally water. This texturing technique by fluid jets well known to those skilled in the art has given rise to an abundant literature.
  • the hot fixing operation is generally carried out by passing the textured paper over a rotary cylinder 30 provided with heating means.
  • the cylinder 30 can for example be heated to a temperature of the order of 200 ° C. It may possibly be of the "through air" type providing for blowing hot air through the sheet. It can also be replaced by a hot air tunnel oven.
  • the present invention now aims to provide a new process for preparing paper for filter bags which improves the properties of the product obtained.
  • a process for preparing paper for filter bags which comprises, after production according to a technique known per se of a nonwoven paper composed of a layer based on synthetic fibers and a layer of superimposed cellulosic fibers, the step consisting in subjecting the nonwoven paper to a calendering operation between a support structure and a heated relief cylinder.
  • the heated cylinder is a metal cylinder.
  • the support structure is formed by a cylinder with a smooth surface.
  • the support structure is formed of a cylinder having in hollow the relief inverted from that of the metal cylinder.
  • the support structure is formed by a cylinder with an elastic flexible external surface, such as a rubberized cylinder.
  • the support pressure between the support structure and the heated relief cylinder is adjustable.
  • the invention also relates to the device for implementing the method and to the product obtained.
  • the heated relief cylinder 140 is a metal cylinder, while the support structure is formed from a rubberized roller, preferably smooth.
  • the support structure may be formed of a cylinder having in hollow the reverse relief of the cylinder 140.
  • the relief metal roller 140 and the support roller 130 are rotated in the direction of travel of the nonwoven paper 112, at the same speed as the latter.
  • cylinders 130 and 140 could be replaced by structures with equivalent endless belts.
  • the relief cylinder 140 can be heated using any conventional means known to those skilled in the art.
  • the contact pressure between the cylinders 130 and 140 is preferably adjustable.
  • the layer of synthetic fibers of the nonwoven paper 112 is preferably placed on the side of the heated relief cylinder 140.
  • the reverse arrangement can however be adopted, in particular to limit the adhesion between the paper and the heated cylinder, at high speed.
  • the reliefs of the cylinder 140 are found in the appearance of the calendered nonwoven 114.
  • the texturing technique by water jets can also risk perforating the cellulosic layer (as shown in dashes in FIG. 3A), thus creating privileged passages of dust.
  • This drawback is completely eliminated thanks to the process of the invention, which therefore makes it possible to manufacture a filter paper free from the usual drawback of textured papers, in other words a paper having an improved ability to retain the finest particles.
  • the patterns made in relief on the cylinder 140 and reproduced on the paper can be the subject of a very large number of variants.
  • the Applicant in particular has produced papers having patterns in the form of dashes, squares, and diamonds.
  • the width of the reliefs of the cylinder 140 that is to say the width 1 of the compressed areas 116 is of the order of 0.1mm to 5mm, preferably from 0.1mm to 2mm, very preferably of the order of 1mm.
  • the total surface of the compressed areas 116 is less than the 5th, very preferably the 10th of the total surface of the paper.
  • the speed of movement of the paper 112, 114 can be of the order of 200 m / min.
  • composition of the paper can be as follows, cellulosic fibers: wood pulp, hemp, flax, etc., synthetic fibers: polyethylene, PVC, polypropylene, etc.
  • the fibers advantageously have a length of a few mm and a diameter of a few ⁇ m.
  • the thickness of the cellulosic layer is typically of the order of 25 to 40 ⁇ m and the thickness of the synthetic layer is typically of the order of 10 to 15 ⁇ m.
  • the density of the paper can be about 0.3.
  • the raised roller 140 is made of steel. It can be heated by oil circulation, at a temperature of 140 to 300 ° C. The contact pressure between the cylinders can be adjusted between 15 to 45 N / mm in width.
  • an additional heating step similar to known step 30, can be carried out before or after calendering 120. This heating operation is however generally not necessary in the context of the invention.
