Abstract
Producing high temperature-resistant technical paper, wherein fibers are mixed with a wet paper material pulp and then technical paper is produced from the pulp by the removal of water from the pulp and resulting compacting of the paper material, it is proposed that the fibers added to the wet pulp are fibers which have been cut and previously thermally pre-shrunk so that in practical use under high temperature conditions the finished technical paper experiences a low degree of thermal shrinkage of less than 1%.
