METHOD FOR PRODUCING HYDROPHILIC CELLULOSE FIBER |
摘要 |
The present invention provide a hydrophilized cellulose fiber producing method, comprising oxidizing cellulose fibers in a reaction solution containing a N-oxyl compound, an oxidizing agent, and a co-catalyst and oxidizing other cellulose fibers using the reaction solution again.;The present invention relate to a hydrophilized cellulose fiber producing method, comprising the steps of: (1a) oxidizing cellulose fibers in a reaction solution containing a N-oxyl compound, an oxidizing agent, and sodium sulfate to provide oxidized cellulose fibers; and (1b) separating the obtained oxidized cellulose fibers from the reaction solution, and then adding other additional cellulose fibers and oxidizing agent to the reaction solution to oxidize the cellulose fibers again to provide oxidized cellulose fibers. |
