Definitions

  • the present invention relates to a manufacturing process a paper with anti-slip properties, as well as the paper obtained by this process.
  • Such paper is obtained in a traditional way on a machine to paper.
  • the paper is resumed to undergo a treatment allowing the deposition of a composition giving it anti-slip properties.
  • This treatment is carried out by transformers, regardless of the papermaking operation.
  • a composition comprising capsules made of a thermoplastic material, and containing themselves a product having a sticky effect (see documents EP-A-0 511 129 and FR-A-2 395 141). During coating and heating, these capsules burst, and allow the sticky product to ensure anti-slip function.
  • the object of the invention is to provide a manufacturing process of a paper having anti-slip properties, which is of a setting simple work, and which allows obtaining a paper whose properties anti-slip are perfectly homogeneous on both sides, and in the different paper directions, eliminating the need for the user to choose a direction of predetermined use to obtain the desired anti-slip properties.
  • the process which it relates to consists in carrying out a strip of paper in a manner known per se inside a paper, to carry out the drying of the paper at the pre-drying station, to carry out coating the paper on both sides with a composition viscous with anti-slip properties, while the paper strip is still at temperature, then pass the strip of paper through a post-drying station.
  • the temperature of the strip of paper, before coating is of the order of 80 ° to 100 ° C, and the temperature of the viscous composition, during coating, is around from 40 to 50 ° C.
  • the strip of paper passes, after coating, in a roller coater by transfer of movie.
  • a roller coater makes it possible to obtain a non-uniform spreading of the viscous composition, which improves its anti-slip properties.
  • Grooved rollers mark the surface condition of the paper further promoting the anti-slip character, and ensuring the paper a character anti-slip in different directions.
  • the starch is wheat starch transformed by enzymation, the gas is butane trapped in polyvinylidene chloride cells, and the inhibitor is zinc sulfate.
  • Figure 1 very schematically represents part of a paper making machine, the area to the left of Figure 1 being designated by the general reference 2 corresponding to the pre-drying station of a strip of paper 3 after formation thereof.
  • the band of paper 3 passes over a series of drying cylinders 4.
  • the paper strip is at a temperature of the order of 90 ° C.
  • the strip of paper then passes through rollers 5 from a coater to rollers, from top to bottom, immediately upstream of which is a tank 6 containing a viscous coating composition.
  • the coating is carried out on both sides of the strip.
  • This strip then passes over two fluted rollers 7, intended to act on the two layers of coating placed on either side of the coated paper, each grooved roller 7 having, as shown in FIG. 2, two 8 helical grooves starting from the center, and unwinding outwards.
  • drying cylinders belonging to the post-drying station of the machine papermaking. At the exit of the machine, the paper is thus obtained with a coating on both sides giving it anti-slip properties, perfectly homogeneous, in the long direction and in the cross direction.
