摘要：
This invention provides a method for hydrophilic treatment of cellulose fibers that can prevent coloring or decrease in fiber strength. The hydrophilic treatment method comprises a first oxidation step of oxidizing cellulose fibers in a first reaction solution containing an N-oxyl compound and a re-oxidizing agent for the N-oxyl compound; and a second oxidation step of oxidizing oxycellulose fibers obtained in the first oxidation step in a second reaction solution containing an oxidizing agent for oxidizing aldehyde groups.
