Oxidation fiber structure

Abstract

The present disclosure relates to an oxidation fiber structure having an oxidation fiber, and the oxidation fiber has an oxidation layer and a core portion, wherein the oxidation layer covers the outer side of the core portion. The microwave processing unit is used to focus the microwave to perform an ultra-fast pre-oxidization process on the passed fiber yarn bunch, thus processing the fiber yarn bunch to form an oxidation fiber yarn bunch. An oxidization time of an oxidation fiber is reduced, and the cross section area of the oxidation layer of the oxidation fiber in the oxidation fiber yarn bunch generated by the microwave focusing oxidization process occupies more than 50% of the cross section area of the oxidation fiber in the oxidation fiber yarn bunch. Thus, the shell-core structure of the oxidation fiber can be reduced efficiently. Even, the oxidation fiber has no obvious shell-core structure.

What is claimed is: 
     
         1 . An oxidation fiber structure, comprising at least one oxidation fiber, wherein the oxidation fiber comprises an oxidation layer and a core portion, wherein the oxidation layer covers an outer side of the core portion, and a cross section area of the oxidation layer occupies more than 50% of a cross section area of the oxidation fiber. 
     
     
         2 . The oxidation fiber structure according to  claim 1 , wherein the cross section area of the oxidation layer occupies more than 60% of the cross section area of the oxidation fiber. 
     
     
         3 . The oxidation fiber structure according to  claim 1 , wherein the cross section area of the oxidation layer occupies more than 80% of the cross section area of the oxidation fiber. 
     
     
         4 . The oxidation fiber structure according to  claim 1 , wherein the cross section area of the oxidation layer occupies more than 90% of the cross section area of the oxidation fiber. 
     
     
         5 . The oxidation fiber structure according to  claim 1 , wherein the cross section area of the oxidation layer occupies more than 99% of the cross section area of the oxidation fiber. 
     
     
         6 . The oxidation fiber structure according to  claim 1 , wherein the oxidation fiber is formed under an exposure of a microwaving condition. 
     
     
         7 . The oxidation fiber structure according to  claim 6 , wherein the oxidation fiber is an organic fiber.
