Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet capable of removing moisture such as odor and moisture. More specifically, the present invention relates to a seat for removing odor and moisture to create a comfortable space in a living room, kitchen, closet or other living environment.

[0002]

2. Description of the Related Art Conventionally, a deodorizing sheet having a structure in which a deodorant is interposed between the front and back holding sheets simply has a deodorant such as activated carbon or zeolite disposed between the front and back holding sheets. The deodorant moves freely between the layers, and a part of the deodorant is generated, or unevenness between the layers is generated, which results in a product with unevenness.

When such a product is placed on a flat place, for example, on a table, a floor or a shelf, it has unevenness without a soft appearance, but it is not "gaman". However, if you use it vertically for some purpose, such as for wall hangings, the deodorant goods inside will be biased downwards, and it will be like a bag with a soft feeling that the items are accumulated on the bottom side, It is not desirable in appearance and loses commercial value. Such inconvenience represents the existence of structural improvement that requires uniform distribution of the deodorant.

[0004]

As described above, in the conventional deodorizing sheet, the deodorant interposed between the front and back holding sheets can freely move between the layers, or the distribution can be uneven. In addition to the poor deodorizing effect caused by structural defects such as being deviated to one place, the deodorizing effect of the conventional deodorant was not always sufficient in practice.

Therefore, the present invention has been made in view of the above-mentioned problems, and by strongly absorbing the bad odor, the bad odor does not drift or remain in the space, and in addition, the deodorant is interposed in the sheet. It is possible to distribute the agent evenly between layers and to maintain a uniform distribution, which can be applied to any application regardless of horizontal, vertical and other conditions, and it can be used structurally with peace of mind. The purpose is to provide a deodorizing sheet with high component value.

[0006]

In order to achieve the above object, the present invention forms a three-layer structure by interposing a deodorant between front and back holding sheets, and embosses from the upper and lower surfaces of the three-layer structure. And the three-layer structure is integrally formed.

[0007]

According to the present invention, the deodorizing agent which is uniformly distributed in the deodorizing sheet and is interposed in the deodorizing sheet disturbs the uniform distribution during use and does not move out of the allowable range. In addition to being expected, the deodorizing ability is stronger than that of conventional deodorizing agents, so that the deodorizing effect can be improved.

The deodorant used in the present invention is Crystbalite, which is a type of silicic acid anhydride.
e) as a main component, with a small amount of quartz, phosphosilicate stone, chlorite, illite, montmorillonite, etc., which is a special pulverized powder of about 200 mesh and is very light and very It is a porous material that has a property of adsorbing gases such as ammonia and ethylene, capable of quickly absorbing "odor" such as garbage, blood, manure and absorbing water. And this deodorant is mixed with an alkaline agent such as caustic soda,
A deodorant having a further deodorizing effect can be obtained.

Particularly, the adsorption capacity of ammonia gas (g /
In g), the value is about 10 times that of activated carbon and zeolite.
Further, it has a deodorizing effect 10 to 30 times that of conventional deodorizing agents. Further, since this deodorant is a natural product, it is completely harmless if it directly comes into contact with livestock or food, or if it is mistakenly eaten by livestock.

[0010]

Embodiments of the present invention will be specifically described below with reference to the drawings. 1 is a cross-sectional view of a deodorizing sheet showing Example 1 of the present invention. The deodorizing sheet of this embodiment is formed by interposing the deodorant 1 in a uniform distribution state between the front and back holding sheets 3a and 3b.

In forming the deodorizing sheet, the deodorizing agent 1 is uniformly and evenly distributed and distributed between the front and back holding sheets 3a and 3b, and then placed on the front and back holding sheets 3a and 3b. About 30 by embossing from the bottom
Both front and back holding sheets 3a and 3b are entirely fixed by heating to 0 ° C. and pressurizing with a pressure of about 4 kg. In other words, the front and back holding sheets 3a and 3b are pressed and heated by the unevenness of the roller surface which constitutes the embossing mechanism, so that the tissue bonding between the front and back holding sheets 3a and 3b in the strongly pressed portion is performed. It becomes a structural connection between male and female, and is strongly and integrally fixed.

As a result, the deodorant 1 is uniformly distributed without being unevenly distributed between the layers and is maintained in a stationary state. Both the front and back holding sheets 3a and 3b can be processed to be long or short depending on the application. In this case, the peripheral edges in the longitudinal direction and the lateral direction are simultaneously processed during sheet processing.
It may be embossed. By doing this, it becomes a solid flat product as a final product.

The front and back holding sheets 3a, 3b constituting the layers of the above deodorizing sheet have good breathability and water permeability to odors and moisture, and heat resistance strength to withstand embossing at about 300 ° C. It is also a good material, and it is advisable to use, for example, a mount processed from virgin pulp.

As the material for the front and back holding sheets 3a and 3b, only one of them may be used, for example, a polyethylene sheet or vinyl may be used for the back holding sheet 3b. When a polyethylene sheet is used, at least one surface of the polyethylene sheet is formed as a non-slip surface that is not coated in order to prevent the outer surface on the side from slipping, and the surface is laminated as an outer surface.

In the deodorizing sheet having this structure, since the holding sheet on at least one surface, for example, the front holding sheet 3a side is made of a material having good air permeability and water permeability, odor and water are permeated and absorbed from this surface. At the same time, it is possible to prevent excessive moisture from seeping out to the side with a polyethylene sheet or vinyl. Further, in the case of a polyethylene sheet, the outer surface is made slippery, so that the position of the sheet does not easily shift when used on the floor surface or the like.

In this embodiment, both front and back holding sheets 3 are used.
Although the three-layer structure in which the deodorant 1 is interposed between a and 3b has been described, the intermediate layer is not limited to the deodorant, and a water absorbing agent polymer may be mixed. This makes it possible to supplement the water absorption capacity and strengthen the water absorption. Further, depending on the purpose of use, a pulp sheet, crushed pulp or the like may be laminated on the upper and lower surfaces of the deodorizing sheet of the present invention to give a soft touch feeling to the sheet and enhance water retention.

As described above, by applying various processes using the deodorizing sheet of the present invention, it is possible to manufacture a sheet that meets a wide range of purposes. For example, as an application example, a diaper, a first aid sheet, a surgical sheet, a bed sheet for a hospital, a comforter, a toilet mat, a sheet for sleeping urine, or a rug or a hanging material in a casket has an excellent deodorizing and water-absorbing effect. can get.

EFFECTS OF THE INVENTION According to the present invention, since a deodorant is interposed in the deodorizing sheet, it is possible to absorb and remove a bad odor and also absorb moisture to create a comfortable space. In addition, when the deodorant inside is installed horizontally, vertically or on an uneven surface, and even when it is wound or twisted, it does not shift to the outside, scatter to the outside, uneven distribution, etc. It is also preferable and has high commercial value. Further, when the sheet is laminated with a surface layer having a non-slip surface on one side, by using this surface as the lower surface, the position of the sheet does not easily shift during use.

Further, since this sheet can be manufactured at low cost, it can be disposable. When discarding, the used odor can be treated together with the raw dust to remove the odor of the raw dust. In addition, when this is incinerated, it is possible to remove the foul odor of flue gas. This makes it possible to deal with a wide range of deodorant water absorption applications.
