Abstract

PURPOSE: To provide a method of producing a material of filter having steps of preparing a homogeneous mixture of powders of a plastic and short glass fibers, compressing the admixture in a mold, baking and cooling the compressed admixture so as to obtain a raw filter material, and then immersing the raw material in a bath of fluoric acid, so as to effect an elution of the glass fibers, thereby to obtain a thin membrane filter material having uniform pore diameter.
