Description

Filter medium for air filter and method for producing filter medium for air filter Technical Field The present invention relates to a filter medium for an air filter and a method for producing the filter medium for an air filter. Background Harmful substances such as mites, pollen, bacteria and the like float in the air. In order to trap and inactivate these floating harmful substances, air filters are mounted on air cleaners and ventilators (for example, patent document 1 and patent document 2). Prior art literature Patent literature Patent document 1 Japanese patent laid-open publication No. 2005-7345 Patent document 2 Japanese patent application laid-open No. 2011-206683 Disclosure of Invention Problems to be solved by the invention However, it is known that the use of a filter medium for an air filter manufactured according to the prior art has a risk of decreasing the antibacterial property in some cases. The present invention has been made in view of the above circumstances, and an object thereof is to provide a filter medium for an air filter which can exhibit excellent antibacterial properties. The present invention also provides a method for producing the filter medium for an air filter. Means for solving the problems The invention provides a filter medium for an air filter, which comprises a base material, an enzyme-containing antibacterial material, an inorganic anti-allergen material and a mold inhibitor, wherein the enzyme-containing antibacterial material, the inorganic anti-allergen material and the mold inhibitor are loaded on the base material. The present invention may further include a colorant supported on the substrate. The present invention also provides a method for producing a filter medium for an air filter, comprising a first loading step in which a colorant is loaded on a base material, and a second loading step in which an enzyme-containing antibacterial material, an inorganic anti-allergen material, and a mold inhibitor are loaded on the colorant-loaded base material. In the present invention, the inorganic anti-allergenic material preferably contains at least one selected from the group consisting of inorganic solid acids and metal inorganic salts. In the present invention, preferably, the colorant contains an organic pigment. In the present invention, preferably, the enzyme contains lysozyme. In the present invention, it is preferable that the loading amount of the anti-allergenic material is less than 3g/m 2. In the present invention, it is preferable that the loading amount of the anti-allergenic material is 0.05g/m 2 or more. In the present invention, preferably, the ratio of the loading of the anti-allergen material to the loading of the mold inhibitor (loading of the anti-allergen material/loading of the mold inhibitor) is less than 100. In the present invention, preferably, the mold inhibitor contains at least one selected from the group consisting of iodopropynyl butylcarbamate, polyaminopropyl biguanide, 2-methyl-4-isothiazolin-3-one, and sodium dehydroacetate. Effects of the invention According to the present invention, a filter medium for an air filter that can exhibit excellent antibacterial properties (even in a high-temperature and high-humidity environment) can be provided. Further, according to the present invention, a method for manufacturing a filter medium for an air filter can be provided. Drawings Fig. 1 is a graph showing the relationship between the amount of the anti-allergenic material and the anti-allergenicity. Detailed Description [ Filter Material for air Filter ] The filter medium for an air filter of the present embodiment comprises a base material, an enzyme-containing antibacterial material supported on the base material, an inorganic anti-allergenic material, and a mold inhibitor. In the present embodiment, an inorganic anti-allergen material should be used together with an enzyme-containing antibacterial material. According to the findings of the present inventors, it is found that when an antibacterial material containing an enzyme and an organic anti-allergenic material are used together, the antibacterial property is greatly reduced according to circumstances. The reason for this is not yet known, but it is assumed that the enzyme may be decomposed (deactivated) by the organic anti-allergen material because the enzyme reacts or interacts with the organic anti-allergen material. (Substrate) The material of the base material may be organic fibers or inorganic fibers. The organic fibers may be fibers such as cellulose, polypropylene, polyethylene, polyester, and polyamide, and the inorganic fibers may be fibers such as glass, magnesium silicate, silica, alumina, aluminosilicate, and zirconia. The form of the substrate may be a nonwoven fabric, a filter paper, a honeycomb, a pellet, a mesh, or the like, and is not particularly limited. The substrate may contain a flame retardant. Examples of the flame retardant include organic flame retardants
