technical field

The present invention relates to an air cleaner capable of reducing allergens caused by mites and pollen. In addition, the present invention relates to a filter sheet for trapping floating particulate matter in air or water and a manufacturing method thereof, and to a functional filter sheet for controlling harmfulness of captured particulate matter and a simple manufacturing method thereof. In addition, the present invention also relates to a filter for capturing floating particulate matter in the air and water and its device, and an air cleaning filter for controlling the harmfulness of captured particulate matter and its use.

Background technique

At present, as such an air cleaner, there is known an air cleaner that sucks polluted air from the front and blows clean air from above (for example, pages 2 to 3 of Japanese Patent Publication No. 63-45607, see FIG. 4 ). This air cleaner will be described below with reference to FIG. 6 .

As shown in FIG. 6 , there is a suction port 101 on the front, and an upward blowing port 102 is provided on the top.

In addition, allergen reducing agents capable of reducing allergens such as mites and pollen are well known (for example, [0033] of JP-A-2003-81727, see Table 1).

In the composition of this existing air cleaner, the suction port 101 is located on the entire surface slightly in front of the body shell 104, and since it is blown out from the top blowing port 102 to the top, it can be blown out from the suction port 104 front of the body shell 104. 101 Inhale cigarette smoke and floating dust and collect them in the filter sheet 105, but it is difficult to inhale pollen falling on the indoor floor and mite corpses and feces contained in dust such as cotton, etc. When the ground is caused by people walking, etc. When the dust on the surface is flying, it will have a bad effect on the human body, and even if it is collected on the filter sheet 105, there is a problem that it cannot be completely deactivated.

In addition, this filter currently filters and captures harmful substances floating in the air such as mites, pollen, bacteria, mold, and viruses. This kind of filter is trying to be widely used in air cleaning as a filter that captures allergenic proteins such as mites and pollen, or harmful substances such as bacteria and viruses, and deactivates the captured harmful substances. machine and ventilator.

However, the anti-allergen filter sheet formed by attaching the anti-allergen agent described in the Japanese publication No. 2000-5531 and the Japanese publication No. 2003-81727 only has an anti-allergen effect when it is alone. There is a problem that additional processing is required for antibacterial and antifungal effects, coloring, and the like.

In addition, the allergen deactivation method described in JP-A-2003-33612 uses a surface heating element made of stainless steel to heat captured allergens to cause protein denaturation for deactivation. However, it has problems such as requiring ancillary equipment and machines such as a heating mechanism, and being very energy-consuming.

In addition, in Japanese Unexamined Patent Application Publication No. 2001-89974, the antibacterial fiber is a substance immobilized with a water-soluble polymer on the surface of the fiber to control bacterial growth. For fixation, it is necessary to use a water-soluble polymer or a polymer that becomes a latex in an aqueous solution, and it cannot be used when a substance causing precipitation is mixed in water, so there is a problem that the raw materials that can be processed are limited.

Therefore, the object of the present invention is to solve these conventional problems, and to provide an air cleaner capable of effectively sucking pollen and mite corpses etc. located near the ground, and exhibiting antiallergic properties for a long time.

In addition, the present invention also relates to a filter sheet for trapping floating particulate matter in air or water and a manufacturing method thereof, and aims to provide a functional filter sheet capable of controlling the harmfulness of captured particulate matter and a simple manufacturing method thereof.

In addition, the present invention also relates to a filter for trapping floating particulate matter in the air or water and its device, and aims to provide an air cleaning filter and its use for controlling the harmfulness of captured particulate matter.

Mixture of water-soluble and water-insoluble materials

As shown in Table 1, water-soluble materials and water-insoluble materials were mixed. After the components were mixed at a ratio (volume ratio) of 15% to the solvent, the mixture was stirred with a stirrer for one minute, and the state of the solution after stirring was visually observed.

In a single-component solvent, if a water-soluble material and a water-insoluble material are mixed, precipitation, two-phase separation, and a state where only a small amount of dissolution is observed. In the mixed liquid in which precipitation occurs and the two phases are separated, it is not suitable for practical use because it cannot be applied uniformly when applied to a filter. In addition, when only a small amount can be dissolved, only a small amount of components can be coated on the filter in one process, so the loss in production is large.

When the ratio of butyl celusoff and water in the mixed solvent is 1:1, it is possible to prepare a treatment solution that dissolves the components without causing precipitation and two-phase separation, so that it can be evenly coated on the filter. Chip. Even if the ratio of butyl celusoff was increased, precipitation did not occur in the treatment liquid. Conversely, when the ratio of water is increased, when the ratio exceeds 1:4, precipitation of components is observed.
