These are processed into a non-woven fabric or woven fabric depending on the purpose of use.
- the anti-allergen filter of the present invention is prepared by, for example, applying a treatment liquid prepared by dissolving and / or dispersing a non-water-soluble polymeric anti-allergen having a phenolic hydroxyl group and a hygroscopic material to a water-containing organic solvent. After that, it can be manufactured by drying.
- Dissolving and dispersing or dispersing a water-insoluble polymer anti-allergen agent having a phenolic hydroxyl group and a hygroscopic material in a water-containing organic solvent requires the use of a water-insoluble polymer anti-allergen agent having a phenolic hydroxyl group and a hygroscopic material. This is because a uniform treatment liquid having an appropriate viscosity must be prepared in order to uniformly impregnate the film.
- the organic solvent is not particularly limited as long as it is miscible with water. Lower alcohols such as ethyl alcohol and isopropyl alcohol, polyhydric alcohols such as ethylene daricoglycerin, and acetone alone are used.

- the total amount of the water-insoluble high molecular weight antiallergen having a phenolic hydroxyl group and the hygroscopic material added to the filter is preferably 1 g / m 2 to 20 gZm 2 . If the amount is too small, the anti-allergen effect will not be sufficiently exerted, while if too large, the pressure loss in the filter will increase.
