Abstract
This invention provides a method for hydrophilic cellulose fibers capable of inhibiting decrease in the degree of polymerization and whiteness degree of oxidized cellulose fibers in oxidized cellulose in which a carbon at position 6 of each glucose unit in the cellulose fiber starting material is oxidized to a carboxyl group, the method comprising (A) the step of performing dehalogenation together with reduction,
