Research Abstract	In order to develop new characteristics for cellulosic natural fibers, such as cotton and lamie as textile fibers, those fibers were chemically oxidized under the mild conditions. When cotton fabrics were treated with TEMPO which is known to be a oxidizing agent for a primary alcohol to a carboxylic acid group under a very mild alkaline condition from pH9.5 to 10.5, those were found to obtain new characteristics similar to lamie fabrics. At this moment, it is still need to improve the treatment conditions for the decreased loss of the strength properties. Lamie and lamie-cotton mixed fabrics were also treated under the similar conditions and their characteristics were evaluated.
