A hydrophilic fibers modified with a substantially water-insoluble inorganic compound is produced by immersing hydrophilic fibers, for example, pulp fibers, in an aqueous solution of a water-soluble inorganic compound (a) selected from aluminates, silicates and zincates of alkali metals with a precipitant (b) containing an aqueous solution of hydrochloric acid or sulfuric acid, adjusting the amount of the aqueous solution impregnated in the hydrophilic fibers to 60 to 400% based on the weight of the hydrophilic fibers, and bringing the hydrophilic fibers with the aqueous solution of the inorganic compound (a) into contact with the precipitant (b), to thereby cause the resultant substantially water-insoluble compound to be precipitated in and fixed to the hydrophilic fibers.
