摘要： Provided are an air filter medium that can be reused with a small decrease in performance by performing a disinfection treatment, a pleated pack, an air filter unit, a mask filter medium, and a method for regenerating an air filter medium. An air filter medium (30) including a fluororesin porous membrane (31) and a supporting member (32) stacked on top of each other has a permeability ratio (permeability after disinfection treatment/permeability before disinfection treatment) of 5.0 or less, the permeability ratio being a ratio of permeabilities of the air filter media (30) before and after the disinfection treatment of the fluororesin porous membrane (31) as determined using NaCl particles having a particle size of 0.1 µm, and a pressure loss ratio (pressure loss after disinfection treatment/pressure loss before disinfection treatment) of 0.83 or more and 1.15 or less, the pressure loss ratio being a ratio of pressure losses of the air filter media (30) before and after the disinfection treatment of the fluororesin porous membrane (31).

摘要： A shaped cross-section composite fiber for an intake filter is manufactured from a single material of polypropylene, without separate binder processing by using the single material of polypropylene as a filter material. The shaped cross-section composite fiber includes: a sheath comprising a reformed polypropylene resin; and a core comprising a polypropylene resin, where the sheath and the core are combined to provide a sheath-core structure.
