Problems solved by technology

[0011] The subject of the present invention is to provide a humidification filter medium and a humidification filter formed using the humidification filter medium, the humidification filter medium solves the problems existing in the conventional technology of the humidification filter medium used in the vaporization type humidifier. Defects, can inhibit the reproduction of the humidification filter medium and the supply water such as mold, bacteria, etc., inhibit the discoloration of the humidification filter medium, the generation of odor, etc., so as to maintain the clean state of the humidifier, when used for a long time, can reduce such as Odor generation, discoloration of the filter medium, etc. can also be suppressed from reducing the physical strength due to the influence of the supplied water

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.

Abstract

The present invention is to provide a humidification filtering material which can reduce the generation of odor and discoloration of the filtering material and can suppress a decrease in the physical strength caused by an impact of supplied water and a humidification filter made by molding the humidification filtering material. The humidification filtering material of the present invention comprises: a felt material; and antibiotic substances contained in the felt material. The internal combination strength of the humidification filtering material is 50-400 mJ. The basis weight thereof is 40-150 g / m^2. The antibiotic substances are antibiotic polyphenol-based compounds. The antibiotic substances are desirable to be one or more types selected from a group made of persimmon tannin extracts, ginkgo leaves extracts, tea extracts, and coffee bean extracts.

Description

technical field [0001] The invention relates to a humidification filter medium and a humidification filter net formed by using the humidification filter medium. Background technique [0002] As the humidification method of the humidifier, there are a vaporization type, a heating type, an ultrasonic type, and the like. The vaporization type refers to a method in which a fan blows air to the humidification filter containing water to vaporize the moisture in the humidification filter. The heating type refers to the use of a heater to heat the water so that the water boils and turns into steam. The ultrasonic method refers to the method in which the water is turned into particles by ultrasonic high-frequency vibration, and the water turned into particles is sent out by a fan. In addition, there is also known a hybrid humidification method used in combination with other methods when the humidity is lowered, although the vaporization method is generally used. In gasification hu...
