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: The antibacterial nanofiber sheet is formed by an electrostatic spinning method. The antibacterial nanofiber sheet contains 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. The nanofiber has a single filament diameter of 10 to 500 nm. Single filaments are prevented from sticking together and filming around single filament intersections where the nanofibers intersect.
