METHOD FOR MANUFACTURING NANO-FIBER USING ELECTROSPINNING, NANO-FIBER, NON-WOVEN FABRIC, SEPARATOR AND THREAD CONTAINING THE SAME

摘要

PURPOSE: A method of manufacturing nano-fibers is provided to obtain nano-fibers with high intensity and uniformity while suppressing use of oil resources or forest resources and reducing impurity. CONSTITUTION: A method of manufacturing nano-fibers containing at least a kenaf originated polymer comprises a process of preparing a kenaf solution by dissolving a kenaf originated polymer in a solvent, in which said Kenaf originated polymer is obtained by performing a solubilization treatment of Kenaf, and a process of performing electrospinning with an electrospinning solution which includes the kenaf solution. The manufacturing method comprises a further process of preparing another polymer solution by dissolving kenaf originated polymer and another different polymer in a solvent before an electrospinning process, and the electrospinning process by using an electrospinning solution which is a mixture solution of a kenaf solution and the other polymer solution. Another polymer includes polyvinyl alcohol. In the mixture solution, the weight ratio of a kenaf originated polymer and another polymer is in range of 1:99-1:1. The solubilization treatment is a carboxymethylation treatment. The nano-fiber includes at least kenaf originated polymer obtained by performing a carboxymethylization treatment, and is manufactured by electrospinning using an electrospinning solution that contains a kenaf originated polymer.
