Abstract: PURPOSE: A dyeing method of nanofiber is provided to facilitate waste water treatment after dyeing since a chromophore function of a residual dye that is not died in the nanofiber and remained in a dying tub is removed by radiation irradiation after completion of a dye process. CONSTITUTION: A dyeing method of nanofiber comprises following steps. In dying nanofiber by using a wet method of immersing the nanofiber in a dye tub, radiation is irradiated onto the nanofiber immersed in the dye tub. A dosage of radiation is 1 kGy to 500 kGy. The radiation is one selected from a gamma-ray and an electron beam. The nanofiber is immersed and dyed by using one process selected from a batch type process or a continuous type process.

Abstract: The present invention relates to a method for manufacturing water insoluble chitosan / polyvinyl alcohol hybrid nanofibers, comprising : manufacturing a chitosan-containing acetic acid aqueous solution by adding chitosan into an acetic acid aqueous solution having less than 60 wt% of acetic acid content and then irradiating radiation to the chitosan-containing acetic acid aqueous solution; manufacturing an aqueous solution for electric radiation by adding polyvinyl alcohol and a cross linking agent into the manufactured chitosan-containing acetic acid aqueous solution; and manufacturing water insoluble chitosan / polyvinyl alcohol hybrid nanofibers by manufacturing chitosan / polyvinyl alcohol hybrid nanofibers by performing electric radiation to the aqueous solution for electric radiation and then performing a heat-treatment to it. The present invention can easily dissolve chitosan with a minimum amount of an organic solvent using radiation, and thereby, produce effects of preventing environmental pollution and energy waste, reducing waste water treatment costs, and further enhancing biocompatibility. In addition, the present invention can omit the process of separately sterilizing the water insoluble chitosan / polyvinyl alcohol hybrid nanofibers manufactured due to disinfection effects produced by radiation irradiation. Thereby, the hybrid nanofibers manufactured by the method of the present invention has excellent biocompatibility, and therefore, is useful as medical material.
