The invention relates to a method for producing high-temperature resistant technical paper, wherein fibers are mixed with wet paper pulp and technical paper is subsequently produced by dehydrating said pulp, thereby causing the paper material to be compressed. According to said method, cut fibers and previously thermally pre-shrunk fibers are added to the wet pulp so that the finished technical paper undergoes low thermal shrinkage of less than 1 % when used at high temperatures.
L'invention concerne un procédé permettant de produire du papier technique à haute résistance thermique, selon lequel des fibres sont mélangées à de la pulpe de papier humide, le papier technique est ensuite produit à partir de la pulpe par déshydratation de la pulpe et par compression de la substance de papier, due au processus de déshydratation. Selon ce procédé, il est prévu d'ajouter comme fibres à la pulpe humide, des fibres découpées et précontractées au préalable par voie thermique, de manière qu'en utilisation pratique à température élevée, le papier technique fini subisse une légère contraction thermique de moins de 1 %.
