METHOD FOR PRODUCING FIBROUS STRUCTURE, CARBON FIBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a fibrous structure, which can easily produce the fibrous structure having a diameter in a range of submicron to several tens nanometers with high throughput while reducing variations in the diameter, and also conduct drawing treatment; a method for producing a carbon fiber for carbonizing the fibrous structure; and the carbon fiber obtained by the producing method.

SOLUTION: The method for producing the fibrous structure has a coagulation step that comprises: spinning a stock solution in which a polymer is dissolved into air or a poor solvent from through fine pores 14 with an average diameter of 10 nm-1 μm formed in anodized porous alumina 12; and then coagulating the polymer to produce the fibrous structure with an average diameter of 10 nm-1 μm. The method for producing the carbon fiber having the coagulation step and a carbonization step and the carbon fiber obtained by the producing method are also disclosed.
