Definitions

  • the present invention lies in the field of obtaining a fibrous preparation for the manufacture of a paper having significant hydrophobicity and opacity in the dry or wet state so as to be able to be affixed, for example, to a bottle of wine or spirits capable by its nature of being stored in a humid environment such as, for example, a refrigerator or an ice bucket.
  • the aim of the present invention is therefore to propose a process for obtaining a fibrous preparation to manufacture a paper having significant hydrophobicity and opacity in the dry or wet state so as to be able to use said paper in numerous uses, said fibrous preparation having the advantage of being able to be manufactured on a single production line.
  • the last step is followed by a step of adding to the fibrous preparation obtained additives and/or dyes usually used in stationery.
  • the fibers are cellulose fibers.
  • the calcium salts have either counter ions of a mineral nature or counter ions of an organic nature.
  • the carbonate salts have counter ions of a metallic nature or the carbonate salts can also be of a mineral or organic nature.
  • the carbonate salts are preferably sodium carbonate.
  • the mass of calcium carbonate produced corresponds to a value of between 20 and 22% of the dry matter.
  • the fatty acid salts comprise between 12 and 22 carbons in their chain and their counter ions can be metallic or organic salts.
  • the fatty acid salts comprise 18 carbons in their chain and will be, preferably, potassium stearate.
  • the fatty acid salts are preferably potassium stearate.
  • the invention also relates to a paper having significant hydrophobicity and opacity in the dry or wet state, remarkable in that it is manufactured from the fibrous preparation receiving particles of calcium carbonate produced by precipitation and fixed directly to the surface and/or in its fibers, and fatty acids adsorbed on the surface of the calcium carbonate particles, and obtained by the process according to the invention.
  • the process according to the invention for obtaining a fibrous preparation for manufacturing a paper having significant hydrophobicity and opacity in the dry or wet state is based on the principle of the precipitation of charges on fibers then on the modification of said fillers in order to make them less hydrophilic.
  • This last step can advantageously be followed by a step of adding to the fibrous preparation obtained additives and/or dyes usually used in stationery store.
  • additives and/or dyes which are well known to those skilled in the art, are such as, for example, alkyl ketene dimers (AKD), cationic starch, anionic pigment dyes, colloidal silica, or further carboxymethylcellulose, in order to give the paper made from the fibrous preparation obtained increased whiteness and opacity.

  8. Gewinnungsverfahren nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, dass die Dosierungen der verwendeten Calciumsalze und Carbonatsalze vorteilhafterweise so bestimmt werden, dass durch Ausfällen eine Masse an Calciumcarbonat hergestellt wird, die höchstens 25 % der Trockenmasse entspricht.
  9. Gewinnungsverfahren nach Anspruch 8, dadurch gekennzeichnet, dass die hergestellte Masse an Calciumcarbonat einem Wert zwischen 20 und 22 % der Trockenmasse entspricht.
  10. Gewinnungsverfahren nach einem der Ansprüche 1 bis 9, dadurch gekennzeichnet, dass die Fettsäuresalze zwischen 12 und 22 Kohlenstoffe in ihrer Kette umfassen und ihre Gegenionen Metall- oder organische Salze sein können.
  11. Gewinnungsverfahren nach Anspruch 10, dadurch gekennzeichnet, dass die Fettsäuresalze 18 Kohlenstoffe in ihrer Kette umfassen und bevorzugt Kaliumstearat sind.
  12. Gewinnungsverfahren nach Anspruch 11, dadurch gekennzeichnet, dass die Fettsäuresalze Kaliumstearat sind.
  13. Papier, das im trockenen oder nassen Zustand eine erhebliche Hydrophobizität sowie Opazität aufweist, dadurch gekennzeichnet, dass es aus der Faserzubereitung hergestellt wird, die durch Ausfällung erzeugte und direkt an der Oberfläche und/oder in den Fasern gebundene Calciumcarbonatpartikel und an der Oberfläche der Calciumcarbonatpartikel adsorbierte Fettsäuren erhält und nach dem Gewinnungsverfahren nach einem der Ansprüche 1 bis 12 gewonnen wurde.
