[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a breathable member used for a filter, a cushioning material, a filling material, a soundproofing material or the like, and particularly when joining breathable materials to each other or joining the breathable material to another article. Also relates to breathable members that ensure the original breathability of the material.

[0002]

[Prior art]

 Conventionally, breathable materials such as urethane, sponge, recycled felt, and non-woven fabric have been widely used as filters and soundproofing materials. In addition, since this type of breathable material is also generally elastic, it is also used as a cushioning material, a filling material, and a soundproof material.

By the way, such a breathable material is not only used alone, but may be used in combination with different types of breathable materials, or may be used while being fixed to another article. Many. For example, in an air filter, the breathable material is laminated in order from the coarse breathable material to the fine material to prevent rapid clogging of the breathable material and effectively capture dust and foreign matter. . In addition, shock-absorbing materials, fillers, sound-insulating materials, etc., when attached to an article that requires them, do not simply apply to the article, but if they are directly joined to the surface of the article that requires it, the article and the breathable material are simultaneously provided. There is also the advantage of being able to handle and move.

Conventionally, a double-sided adhesive tape or an adhesive has been used for joining breathable materials to each other or joining to other articles as described above. (There are some double-sided adhesive tapes and adhesives that simply have tackiness and should be called adhesives to be precise. However, in the present specification, these are collectively referred to including the claims. It is called adhesive or adhesive.)

[0005]

[Problems to be Solved by the Invention] However, when a double-sided adhesive tape is used to bond the breathable material, since the commercially available tape has a width of about 5 mm, the pores of the material are However, there was a problem in that the material was blocked by the tape, and as a result the original breathability of the material was lost. In order to avoid this, it is necessary to stretch the tape at a certain interval such as a grid, but it is necessary to attach many tapes, which makes the work troublesome and evenly stretches the gaps evenly. However, it was difficult to perform reliable bonding. In particular, if the tape width is narrowed to ensure air permeability, the number of tapes to be used becomes enormous when joining a large area of air-permeable material, and the amount of work is extremely large.

On the other hand, when joining breathable materials with an adhesive, it is necessary to apply the adhesive in a dot or grid pattern with an interval sufficient to ensure breathability, which must also be done manually. However, there is a drawback that it requires a dedicated coating device.

The present invention solves the above-mentioned problems of the prior art, and has an adhesive property that enables easy bonding with other members without impairing the air permeability, which is the greatest feature of the air permeable material. An object is to provide a breathable member.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the breathable member according to claim 1 is adhered to a net having adhesive layers formed on both sides of a mesh, and to at least one side of the net via an adhesive layer on the surface of the net. It is characterized by being made of breathable material.

A breathable member according to a second aspect is the breathable member according to the first aspect, wherein the breathable material is bonded to one surface of the net and the release paper is bonded to the other surface.

A breathable member according to a third aspect is the breathable member according to the first aspect, wherein a breathable material is bonded to one surface of the net and another breathable material is bonded to the other surface. Characterize

A breathable material according to a fourth aspect is the breathable member according to the first aspect, wherein the breathable material is an elastic sheet.

[0012]

[Action]

 In the breathable member according to claim 1 having the above structure, since the adhesive layer is limited to the mesh portion of the net, the adhesive layer does not block the air holes of the material, and the other member is Even when joined, the original breathability of the materials can be secured. In addition, since the adhesive layer is formed along the mesh of the net, the adhesive can be evenly distributed over the entire bonding surface at a predetermined interval, which may cause partial unevenness of the adhesive force. Absent. Also, since the joining work can be performed by simply sticking one net to the breathable material and other members that join it, compared to the case of sticking or applying double-sided adhesive tape or adhesive at intervals. Therefore, the joining work is easy.

The breathable member according to claim 2 is a simple operation of peeling off the release paper covering the surface and pressing the net against the other article, and is easily performed while keeping the surface of the other article breathable. Can be joined to.

In the breathable member according to claim 3, since a plurality of breathable materials are joined by a net having an adhesive layer, different breathable materials are laminated to form a single breathable material. It is possible to obtain a member having a ventilation performance that has not been obtained.

In the breathable member according to the fourth aspect, since the breathable material is composed of the elastic sheet, it is suitable for use in a place where breathability and cushioning property are required.

【Example】

 An embodiment of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a breathable member with a net according to the present invention. In the figure, 1 is a sheet-like breathable material such as urethane foam or recycled felt, and 2 is a surface thereof. It is an established net. The net 2 is made by weaving a natural fiber such as cotton or hemp or a chemical fiber such as nylon or polyester into a net shape, or punching various plastic films into a net shape or heat-welding it. However, a glass cloth woven in a net shape is used in this embodiment.

An adhesive layer 3 is formed on both surfaces of the net 2 by means such as coating, impregnation and spraying, and the net 2 is formed on the surface of the breathable material 1 by the adhesive layer 3 on one surface. It is glued. The surface of the net 2 which is not adhered to the breathable material is covered with a release paper 4 such as a separate paper or a plastic film whose adhesive layer 3 is impregnated with silicone resin.

When manufacturing the breathable member of the present embodiment having such a configuration, as shown in FIG. 2, the release paper 4 is pulled out from the roll and is conveyed by a conveyor or the like. After being pulled out, a net 2 coated with adhesive 3 on both sides is superposed along the mesh by a gluing device 6, and a sheet-like breathable material 1 is superposed on the surface of the net 2 to obtain a product. Of course, an adhesive layer 3 is formed on both sides in advance, and a net 2 having a release paper 4 attached to the surface of the adhesive layer 3 is prepared, and the net 2 is bonded to the surface of the sheet-shaped breathable material 1. May be.

In the case of using the air-permeable member having adhesiveness of the present embodiment configured as described above, the release paper 4 covering the surface of the net 2 is peeled off to expose the adhesive layer 3. The air-permeable material 1 is bonded to the surface of another article by using this adhesive layer 3. Fig. 3 shows an example of a filter manufactured in this way, in which a breathable material 1 having a coarse mesh and another breathable material 5 having a finer mesh are joined by a net 2 having an adhesive layer. Has been.

The breathable member of the present embodiment having such a configuration can be used, for example, in the following applications by appropriately selecting the breathable material 1 and other articles for joining the breathable material 1 in addition to the filter shown in FIG. Can be used for.

A wallpaper or a decorative plate having air permeability is attached to the surface of the soundproof material. Put soundproof material on the front and back of porous sound absorbing board or hard board. A composite type filter is obtained by laminating plural kinds of breathable materials. A breathable material having different colors is laminated to obtain a filter or a cushioning material. Since the breathable material naturally has moisture permeability, water permeability, and water absorption, a water or oil filter other than air or gas is obtained.

Furthermore, the present invention is not limited to the above-mentioned embodiment, but includes the following other embodiments.

The breathable material is not limited to a sheet-shaped material, and other shapes such as a block-shaped material and a thin sheet-shaped material such as cloth and a plastic sheet can also be used. In addition to urethane and sponge-like elastic materials, hard porous materials can be used as the breathable material. By forming the net itself from an adhesive resin, the adhesive layer can be integrated with the net.
