[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sheets for use in futons and beds, and more particularly to magnetic sheets having a deodorizing effect in the material and mainly used for beds for bedridden patients in hospitals and homes. About sheets.

[0002]

2. Description of the Related Art Sheets are generally known to be variously devised in terms of water resistance and water absorption, but in reality, little consideration is given to deodorizing properties.

[0003]

[Problem to be solved by the invention] However,
Sheets of so-called bedridden patients at hospitals, homes, etc. are not protected from the attachment of bad odors due to sweat, excrement, etc., and there is a strong demand for improved deodorizing surfaces. With the conventional method of removing odors by washing, etc., the generation of bad odor during use cannot be avoided, giving the patient as well as the surrounding people discomfort, which again causes a mental burden on the patient. Has also become.

[0004] Accordingly, an object of the present invention is to provide a sheet which can be produced easily and inexpensively without a sense of incongruity in use, because of a long-term deodorizing action during use.

[0005]

Means for Solving the Problems The present inventors have conducted various tests,
As a result of the analysis, it was found that the magnetic force was particularly effective in adsorbing and deodorizing xylene and ammonia generated from sweat, manure, etc., and mixed with chip-shaped magnetic material in cloth, nonwoven fabric, nonwoven paper, etc. Paying attention to the fact that the sheet retains flexibility,
The object has been achieved by including a cloth, a nonwoven paper or a nonwoven paper magnetic sheet in which a magnetic material is mixed in the sheet material.

[0006] The magnetic sheets used for the sheets are substantially uniformly mixed with a chip-shaped magnetic material formed into a sleeve by coating a magnetic material such as iron oxide on the surface of a synthetic resin film. At the same time, it is desirable that the magnetic material be magnetized to have a uniform magnetic force of 2.5 to 10 Gauss, preferably 5 to 7 Gauss.
The reason that the magnetic force was specified to be 2.5 to 10 Gauss
If it is less than ウ ス, it adsorbs xylene and ammonia from the sheets,
It is not enough to deodorize, and the magnetic force of 10 gauss
If obtained, xylene and ammonia for the purpose of sheets
Adsorption and deodorization effects are sufficient, and more than that, magnetic material
Effect only by increasing power consumption to increase magnetic force
This is because there is no significant difference.

[0007]

The odor elements such as xylene and ammonia are adsorbed by the magnetic force from the magnetic material mixed in the sheet material, and these odors are removed from the sheet. In addition, this magnetic force improves heat retention and promotes blood circulation.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partially cutaway plan view of a sheet according to an embodiment of the present invention, and FIG. 2 is an enlarged sectional view of a material used for the sheet of the present invention. The material 2 of the sheet 1 according to this embodiment is, as shown in FIGS.
A part or all of the outer material sheet 3a and the lining sheet 3b
It is composed of a three-layer sheet in which a magnetic non-woven fabric 4 is sandwiched (in a layered manner).

The magnetic non-woven fabric 4 is preferably formed by substantially uniformly distributing and mixing chip-shaped magnetic materials 4b in a raw material 4a made of thermoplastic synthetic resin fibers such as polyester, polyamide, polypropylene or polyethylene. It becomes.

Such a magnetic sheet 4 is disclosed in, for example,
As described in Japanese Patent No. 9948, after a chip-shaped magnetic material 4b is mixed substantially uniformly with a material 4a such as a hot-melt nonwoven fabric, the magnetic material is magnetized, and a substantially uniform It is magnetized.

As a material of the magnetic material 4b, a synthetic resin film having a surface coated with a magnetizable substance such as iron oxide is stretched under heat, whereby the magnetizable substance is turned into a sleeve with its front side facing. It is suitable to be formed into a rounded filament and cut into a chip having a length of 1 to 10 mm, preferably 3 to 5 mm.

The magnetic force of the magnetic sheet 4 suitable for deodorizing the sheets is about 2.5 to 10 gauss. To obtain the most efficient effect, the magnetic force of the magnetic sheet 4 should be 5 to 7 gauss. Is preferred.

As the sheet material in which the chip-shaped magnetic material 4b is mixed, known fiber materials such as natural fibers and synthetic fibers can be appropriately selected and used. Thermoplastic fibers such as polyamide fibers, polypropylene fibers and polyethylene fibers are preferred.

Next, as a test example of the deodorizing performance of the magnetic sheet 4 used for the sheet of the present invention, a magnetic nonwoven fabric will be described below.

Test Example 1 A magnetic nonwoven fabric having a size of 5 × 10 cm ² and a maximum magnetic flux density at an arbitrary test point of 2.9 to 3.3 Gauss was used.
One in a liter vacuum collection bottle, 199.0 ppm
Of xylene was introduced into the collection bottle and stirred, and after the elapse of a predetermined time, xylene was sampled and analyzed by gas chromatography.
Table 1 shows the results as compared with the case where no is inserted.

[0016]

[Table 1]

[Test Example 2] Four magnetic non-woven fabrics under the same conditions as in the above experiment were inserted into a 20-liter tedlar bag, 115.0 ppm of ammonia was introduced into a collection bottle, and the mixture was stirred.
of ammonia (11% / min) for 4 minutes in a double impinger containing 1 l of an absorbing solution (0.5% boric acid), absorb the solution, transfer it to a 250 ml flask, transfer it to a constant volume, and take 5 ml. The result of analysis by phenol blue absorptiometry and the calculation of the concentration, 115 ppm of ammonia was introduced into a collection bottle with 5 liters of Tedra bag (magnetic non-woven fabric was not inserted), and then stirred.
Of ammonia (0.5% boric acid) into a double impinger for 4 minutes to absorb and absorb ammonia at 1 liter / min, wash into a 250 ml flask, and transfer to a constant volume.
Table 1 shows the results of comparison of the adsorption amount of the container itself (the adsorption amount in the state where the magnetic nonwoven fabric is not inserted) calculated by dispensing ml and analyzing by indophenol blue absorption spectrophotometry.

Further, Table 2 shows the experimental results of the amount of adsorption after 24 hours using each of the above magnetic nonwoven fabrics.

[0019]

[Table 2]

As is clear from the experimental results in Tables 1 and 2, the magnetic nonwoven fabric was 199.0 p.
pm after 1 hour to 90.0 ppm
Reduced to 67.9 ppm after 4 hours (199.0 ppm-(after 24 hours) without using magnetic nonwoven fabric)
→ reduced to 156.1 ppm). For ammonia, the concentration of 115.0 ppm was increased to 70.8 pp after one hour.
m and 24 hours later, to 69.1 ppm (115.0 ppm without using a magnetic nonwoven fabric).
-(After 24 hours) → reduced to 94.0 ppm). further,
Regarding the adsorption amount after 24 hours, the results of xylene and ammonia were 527.0 μg / g and 81.3 μg / g, respectively, and an extremely high deodorizing effect was confirmed.

FIGS. 1 and 2 show the outer layer 3a and the inner layer 3 of the sheets.
Although the case where the magnetic sheet 4 is interposed between b is illustrated,
The magnetic sheet 4 itself may be used as the material of the sheet 1.

The magnetic sheet 4 may be used on the entire surface of the sheet, but is not necessarily limited to this configuration, and may be locally applied to a portion where smell is likely to be applied.

In the embodiment shown in FIG.
Is exemplified, but non-woven paper may be used instead of the non-woven fabric, and the magnetic material 4b may be supported on the cloth.

[0024]

[Effect of the Invention] In the present invention, since the sheet itself contains a magnetic sheet that absorbs xylene and ammonia well, the smell of sweat and excrement is effectively deodorized over a long period of time by the magnetic force. In particular, magnetic materials are small chips.
As a result, a uniform magnetic force acts on the entire sheet.

Also, the magnetic material is composed of small particle chips,
Since this is uniformly mixed in a soft sheet such as cloth, nonwoven fabric, nonwoven paper, etc., there is flexibility and there is no uncomfortable feeling in use.

Further, the magnetic force improves heat retention, prevents moisture, promotes blood circulation, is also good for health, and has a large secondary effect such as preventing generation of static electricity.
