Abstract
Official abstract text for this publication.
The present invention provides 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 relates to a hydrophilized cellulose fiber producing method, comprising the steps of: (1 a ) oxidizing cellulose fibers in a reaction solution containing a N-oxyl compound, an oxidizing agent, and sodium sulfate to provide oxidized cellulose fibers; and (1 b ) 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of reusing a reaction solution, comprising steps of: oxidizing cellulose fibers in a reaction solution comprising a N-oxyl compound, an oxidizing agent, and sodium sulfate so as to provide oxidized cellulose fibers; and separating the oxidized cellulose fibers from the reaction solution used in the oxidizing step, and then adding other cellulose fibers and an oxidizing agent in the reaction solution so as to oxidize the added cellulose fiber…
