ANTIBACTERIAL NANOFIBER SHEET, METHOD FOR MANUFACTURING THE SAME, AND FILTER

摘要

PROBLEM TO BE SOLVED: To provide an antibacterial nanofiber sheet having high antimicrobial activity due to inclusion of an antibacterial agent having a particle diameter larger than a single filament diameter, and preventing the antibacterial agent from easily dropping off.SOLUTION: There is provided a nanofiber sheet formed by an electrostatic spinning method, and containing a nanofiber including an inorganic antibacterial agent having an average particle diameter that is larger than a single filament diameter of the nanofiber and smaller than 40 times the single filament diameter of the fiber. There is provided a method for manufacturing the antibacterial nanofiber sheet comprising: preparing a polymer molten liquid or a polymer solution obtained by adding an inorganic antibacterial agent having an average particle diameter that is larger than a single filament diameter of the nanofiber and smaller than 40 times the single filament diameter of the fiber; and forming a nanofiber from the polymer molten liquid or the polymer solution to integrate the nanofiber into a sheet form. There is provided a filter composed of the nanofiber sheet.
