| abstract |
A mold-preventing air filter filtration medium loaded with a water-retaining macromolecule polymer, a mold-preventing agent, and a binder resin, is formed by immersing a filter material or a reinforcing nonwoven fabric (a backing material) in a mold-preventing composition in which the water-retaining macromolecule polymer, the mold-preventing agent and the binder resin are dissolved, and drying the filter material or the reinforcing nonwoven fabric. The reinforcing nonwoven fabric (a backing material) may be bonded to a filter material to form a mold-preventing air filter filtration medium. A mold-preventing air filter includes the mold-preventing air filter filtration medium that is pleated and accommodated in a frame. |
