(57) [Abstract] [Purpose] For example, a Gurley air permeability of 200 g / m 2 basis weight and a high degree of air permeability of about 1 second to 200 seconds / 100 ml air. Provided is a method for producing an aramid molded product by wet papermaking. [Arrangement] 90/10 to 10/9 of aramid paper pulp of a specific size obtained by crushing aramid paper and non-aramid fiber A mixed paper is made into a sheet at a weight ratio of 0. Preferably, at least a part of the aramid paper pulp is heat-treated at a temperature not lower than the glass transition temperature of aramid. [Effect] A porous sheet-like aramid molded product with high air permeability, which could not be realized by conventional wet papermaking, Can be manufactured at low cost using waste aramid paper. |
