Modified cellulose regenerated fiber comprising chitosan particles

Abstract

The present invention is to provide a modified cellulose regenerated fiber having a practically endurable tenacity, and being excellent in dye-affinity, and having anti-funguses and deodorizing properties. The present invention comprises preliminarily molding chitosan or acetylated chitosan into a fine particle, mixing the fine particle body with cellulose viscose prior to spinning, and spinning the mixture, at the inclusion regenerated fiber.

What is claimed is: 
     
       1. Modified cellulose regenerated fiber containing fine particles .Iadd.having a diameter less than 10 μm of a material .Iaddend.selected from the group consisting of particles .[.having a diameter less than 10 μm of a material.]. .Iadd.of .Iaddend.regenerated chitosan and particles of regenerated acetylated chitosan wherein the mixing amount of said fine particles to the cellulose element of said modified cellulose regenerated fiber is at least 0.5% by weight. 
     
     
       2. Modified cellulose regenerated fiber as claimed in claim 1, wherein the mixing amount of said fine particles to the cellulose element of said modified cellulose regenerated fiber is in a range of 0.5 to 2.0% by weight. 
     
     
       3. Modified cellulose regenerated fiber as claimed in claim 1, wherein said modified cellulose regenerated fiber is rayon viscose fiber and polynosic viscose fiber. 
     
     
       4. Modified cellulose regenerated fiber as claimed in claim 1, wherein said modified cellulose regenerated fiber is obtained by mixing said fine particles with cellulose viscose, and spinning the mixture. 
     
     
       5. Modified cellulose regenerated fiber as claimed in claim 1, wherein said modified cellulose regenerated fiber is provided with deodorizing property. 
     
     
       6. Modified cellulose regenerated fiber as claimed in claim 1, wherein said modified cellulose regenerated fiber is provided with an anti-fungus property.
