Process for modifying hydrophilic fibers with substantially water-insoluble inorganic substance.

摘要

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) which is precipiTated when brought into contact with a precipitant (b), adjusting the amount of the aqueous solution impregnated in the hydrophilic fibers to 60 to 40% 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 in the state of an aqueous solution to thereby cause the resultant substantially water-insoluble compound to be precipitated in and fixed to the hydrophilic fibers.
