Abstract:
The present invention relates to cellulose fibers wherein a part of the hydroxyl groups of the cellulose have been substituted with at least one of a carboxy group and formyl group of 0.1 mmol/g or larger based on the weight of the cellulose fibers, and have been further substituted with a chemical modification group other than the carboxy and formyl groups.
