METHOD FOR PRODUCING INORGANIC FIBER PAPER

PROBLEM TO BE SOLVED: To provide a method for producing an inorganic fiber paper in which the inorganic fiber paper having a low basis weight and obtainable by wet papermaking of an inorganic fiber mainly consisting of an inorganic fiber having fine diameter, e.g. glass fiber or ceramic fiber can continuously be produced in a stable quality. SOLUTION: In the method for producing the inorganic fiber paper having ≤14 g/m2basis weight and obtained by performing wet papermaking of inorganic fiber containing ≥50 mass% inorganic fiber having ≤5 μm average fiber diameter, the relationship D/W between a raw material liquid concentration (raw material concentration of raw material liquid) D in wet papermaking and the basis weight W of the paper is kept to ≤0.005.
