Abstract

(57) [Summary] [PROBLEMS] To provide a flexible and stretchable material even in a dry state, and to tie refrigerant with a long roll product, shoe soles, underwear, inside a tea caddy-shaped container, and a bellows-shaped filter to bind refrigerant. It can be widely used for drying and other types of drying, dramatically expanding the field of application. SOLUTION: Instead of paper pulp conventionally used as a main material of a desiccant main body 2, an artificial fiber such as rayon having flexibility and elasticity even in a dry state is used to form a sheet.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is mainly used for drying long-roll products, shoe soles, underwear, inside of a tea-tube-shaped container, a refrigerant, etc. by binding it with a bellows-shaped filter, and is also widely used for other drying. The present invention relates to a desiccant.

[0002]

[Prior art]

 Conventionally, when a desiccant is required to protect the product from moisture, a granular or solid desiccant or a hard sheet-shaped desiccant mainly made of paper pulp for paperboard is placed in a small bag, This was moisture-proof wrapped with the product.

[0003]

[Problems to be solved by the invention]

 However, conventional sheet-shaped desiccants are used in a wide range of fields due to the convenience of sheet-like shapes.However, since paper pulp for paperboard is used as a main raw material, the material is hard in a dry state, and forcibly. The product, its packaging and container are flexible because they are easily broken when bent and there is no flexibility or elasticity in shape, or inside a container without a flat gap where a sheet-like desiccant can be loaded. In some cases, useless space may be created in the package, or a feeling of foreign matter may accompany the use of the product, which may necessitate giving up.

[0004] As described above, since the conventional sheet-shaped desiccant is mainly made of paper pulp for paperboard, it breaks when bent in a dry state, and therefore cannot be loaded into a bent gap or a bent gap. And the fact that it is not possible to wrap the product in such a way that it cannot be wrapped, that it is difficult to handle itself if it is formed in a very elongated shape, that it cannot be rolled up, and that it is difficult to form itself in a bellows shape. There was a problem.

Therefore, the present invention has been devised to solve the above-mentioned problems, and has flexibility and elasticity even in a dry state, so that a roll-shaped long product, a shoe sole, and underwear can be provided. It can be used widely for drying refrigerants, etc. in a tea tube-shaped container or in combination with a bellows-shaped filter, and can be used widely for other types of drying. Is provided.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the sheet desiccant of the present invention uses rayon, which has flexibility and elasticity even in a dry state, instead of the conventionally used paper pulp as the main raw material of the desiccant body. It is formed into a sheet shape using the artificial fiber of the above.

[0007] Furthermore, the upper and lower surfaces of the desiccant body are respectively coated with films with reduced moisture permeability.

[0008] Furthermore, the upper and lower surfaces of the desiccant body are respectively coated with films having moisture absorption holes.

[0009]

[Embodiment of the invention]

 Hereinafter, as a preferred embodiment of the present invention, a description will be given of a state in which a refrigerant or the like is dried by being tied with a roll-shaped long product, shoe soles, underwear, a tea container-shaped container, and a bellows-shaped filter, with reference to the drawings.

As shown in FIG. 1 to FIG. 3, the sheet-shaped desiccant 1 of the present invention is used as a main raw material of the desiccant main body 2 in place of the conventionally used paper pulp. It is formed into a sheet using artificial fibers such as rayon.

Further, the upper and lower surfaces of the desiccant main body 2 are respectively coated with films 3 having suppressed moisture permeability.

Then, the upper and lower surfaces of the desiccant body 2 are covered with films 4 having moisture absorption holes, respectively.

[0013] That is, as the type of the artificial fiber, general rayon is processed into a sheet shape, and any type of artificial fiber may be used as long as it has a water retention ability equal to or higher than that of paper pulp. Can be used for

[0014] The active ingredient as a desiccant is a conventional sheet-shaped desiccant, which is used to impregnate rayon with the most frequently used calcium chloride. From the viewpoints of efficacy and safety, camsium chloride is the most effective as the active ingredient, but other active ingredients, for example, silicic anhydride, may be used from the viewpoint of production.

The sheet-shaped desiccant 1 of the present invention can be used as it is by cutting it into a desired size as it is in the same manner as the conventional sheet-shaped desiccant, or the detailed specification is changed for each application. You can also.

For example, in the case of an application that requires a moisture absorption speed, as shown in FIG. 1, only the desiccant body 2 is used for cutting without coating, and in the case of an application that requires more sustainability than the moisture absorption speed. In FIG. 2, the upper and lower surfaces of the desiccant body 2 are coated with films 3 having suppressed moisture permeability, respectively, and as shown in FIG. After coating each of the films 4 having the film, the film 4 is cut and processed so that it can be adapted to the intended use.

[0017] In addition, both the conventional paper pulp and the artificial fiber used in the present invention are made of almost any tree species such as plants, conifers and hardwoods, and cellulose extracted from linters (cotton short fibers) as main raw materials. In principle, the raw materials in a broad sense remain the same, but the conventional problems can be solved by using artificial fibers such as rayon which has flexibility and elasticity even in a dry state. Thus, the field of application of the sheet desiccant 1 can be greatly expanded.

Next, the use state of the sheet desiccant 1 of the present invention will be described. As shown in FIG. 4, the sheet desiccant 1 is used so as to be wrapped around a long product 5 wound in a roll requiring moisture proof. The shoe sole 6 formed into a shoe sole mold as shown in FIG. 5 is laid in a gap between the uneven surfaces of the shoe sole, and is deformed according to the unevenness of the shoe sole to be used. As shown in FIG. 6, wet underwear 7 (or other clothes) may be put into a moisture-proof bag 10 and wrapped around it, or a curved surface of a container 8 having a curved surface such as a tea caddy as shown in FIG. The filter can be used for drying a refrigerant by being combined with a bellows-shaped filter 9 as shown in FIG. 8, or can be widely used for other drying.

[0019]

[Effect of the invention]

 As described above, the sheet-shaped desiccant 1 of the present invention uses, as the main raw material of the desiccant body 2, man-made fibers such as rayon, which has flexibility and elasticity even in a dry state, instead of the conventionally used paper pulp. Since it is used and formed into a sheet, it can have flexibility and stretchability even in a dry state. Therefore, as shown in FIG. 4, a roll-shaped long product 5 which needs moisture proof, or as shown in FIG. The sole 6 is formed into a sole type as described above, the undergarment 7 is wet as shown in FIG. 6, the inside of a tea tube-shaped container 8 is shown in FIG. Not only can it be used when drying refrigerants and the like in combination with it, but it can also be widely used for other types of drying, greatly expanding the field of application.

Moreover, the sheet-shaped desiccant 1 of the present invention formed only with the desiccant body 2 as shown in FIG. 1 is most suitable for applications requiring a high moisture absorption speed, and is shown in FIG. As shown in FIG. 3, the upper and lower surfaces of the desiccant body 2 are coated with films 3 having reduced moisture permeability, respectively, and the upper and lower surfaces of the desiccant body 2 are coated with films 4 having moisture absorption holes, as shown in FIG. These are most suitable for applications that require sustainability rather than moisture absorption speed, and therefore can be reliably adapted to the applications to be used.
