Embodiment 1
[0063] Persimmon lacquer extract and acrylic adhesive (manufactured by Japan Coating Resin Corporation, trade name: RIKABOND (registered trademark) FK-68H) were mixed in a dry mass ratio of 1:1 to obtain persimmon lacquer Extract dispersion. Then, with internal bonding strength of 47mJ and weight per unit area of 93g / m 2 Polyethylene terephthalate (PET): rayon=50:50 (dry mass ratio) spunlace non-woven fabric is used as the non-woven fabric substrate, and the non-woven fabric substrate is impregnated with this solution Processed so that the dry content of persimmon lacquer extract is 3g / m 2 . After the impregnation, it was dried for 10 minutes in a hot air drier at an internal temperature of 150° C. to obtain a humidified filter medium.
Embodiment 2
[0065] Except that the non-woven substrate is used with an internal bond strength of 246mJ and a weight per unit area of 94g / m 2 PET: rayon = 50:50 (dry mass ratio) spunlace non-woven fabric as the non-woven fabric base material, other use the same method as Example 1 to obtain the humidification filter medium.
Embodiment 3
[0067] Except that the non-woven substrate is used with an internal bond strength of 394mJ and a weight per unit area of 95g / m 2 PET: rayon = 50:50 (dry mass ratio) spunlace non-woven fabric as the non-woven fabric base material, other use the same method as Example 1 to obtain the humidification filter medium.
