Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tourmaline-containing sheet technology that is useful for improving the health of the user and improving sleep.

[0002]

[Prior art]

 Tourmaline is widely known as a beautiful gem for "hope" and as a birthstone for October. Tourmaline, also called tourmaline, has electrodes at both ends of the crystal, which have the property of maintaining the potential forever, the property of generating pyroelectricity, the property of generating far-infrared rays, etc. It is known that it has a positive effect on human health, such as activation of skin cells, promotion of metabolism and blood circulation.

[0003] As a technique utilizing such excellent properties of tourmaline, a technique described in Japanese Utility Model Registration No. 3 037418 proposes a tourmaline fine powder coated sheet. This sheet was excellent in flexibility and made full use of the effects of tourmaline. However, it was found that the effect of this sheet was diminished by repeated use.

[0004]

[Problems to be solved by the invention]

 An object of the present invention is to improve the conventional problems described above, that is, to provide a tourmaline-containing sheet whose effect is not reduced by repeated use.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the tourmaline-containing sheet of the present invention is a tourmaline-containing sheet having tourmaline and titanium dioxide.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The tourmaline-containing sheet of the present invention can be obtained, for example, by providing a layer having tourmaline and titanium dioxide on a flexible sheet-like base material. The sheet-like substrate may be selected from non-woven fabric, woven fabric, knitted fabric, synthetic resin film, paper and the like, and these may be used in a single layer or in a laminate.

[0007] However, in consideration of the texture or the touch, it is desirable to use a nonwoven fabric, a woven fabric, or a knitted fabric as the sheet-like substrate. This sheet-shaped substrate may be conductive or non-conductive.

The layer containing tourmaline and titanium dioxide may cover one or both surfaces of the sheet-like substrate, or may partially cover the sheet-like substrate, such as a polka dot pattern. In the latter case, the effect of the present invention can be obtained without impairing the feel of the sheet-like substrate, and the occurrence of obstacles such as wrinkles is small. The arrangement pattern of the layer having tourmaline and titanium dioxide can be variously selected such as a lattice, a dot, and a line. The layer having tourmaline and titanium dioxide can be formed by, for example, mixing powdered tourmaline and powdered titanium dioxide into a binder and applying the mixture to a base material.

[0009] Tourmaline is generally known as a gem, but in the present invention, it is not such a gem tourmaline, but a coke-shaped black opaque stone or red which is extremely inexpensive and not valuable as a gem. Opaque stones can be used, and other tourmaline ores can be used. Such tolmaline ore can be obtained relatively easily and inexpensively from tourmaline producing countries such as Brazil.

[0010] Such a tourmaline can be applied to a wider range of applications, for example, by making it into a powder. That is, powdered tourmaline is used in combination with an acrylic acid ester resin, a polyurethane resin, a methacrylic resin, a melamine resin, a vinyl chloride resin, a silicone resin, etc. as a binder, and a suitable solvent is mixed with these, if necessary. Add a thickener, colorant, volatile agent, etc. to produce an ink, print it on a flexible substrate using a method such as screen printing or roll printing, and heat or air dry. A tentering set (so-called baking, that is, elongating a contracted base material such as a nonwoven fabric to a constant width) is performed. At this time, it is also possible to select a coloring agent and perform multicolor printing.

The amount of the powdered tourmaline and the powdered titanium dioxide mixed into the ink is 5 to 45% by weight. If it is less than 5%, the effect of mixing tourmaline does not appear so much. If it exceeds 45%, ink properties are impaired, making application difficult, and the flexibility and feeling of the substrate may be impaired.

The tourmaline-containing sheet of the present invention is a sheet having a layer having tourmaline and titanium dioxide, a fiber containing powdered tourmaline inside or outside, and a powdered titanium dioxide inside or outside. And a sheet composed of fibers containing both of them. Further, a sheet-like substrate containing any one of the powders in the fibers may be used. A sheet formed by providing a layer having the other powder may be used.

When the powder is used as described above, if the average particle size exceeds 20 μm, the unevenness of the coat layer becomes large, giving the user a sense of incongruity and impairing the flexibility of the sheet. It is not preferable.

It is desirable that the amounts of tourmaline and titanium dioxide be 10 g / m ² or more and 50 g / m ² or less. That is, if the amount is less than 10 g / m ² , the effect of the compounding may not be obtained. If the amount is more than 50 g / m ² , the effect of the compounding is saturated and the flexibility of the sheet is hardly maintained, which is not preferable.

In the sheet of the present invention, tourmaline and titanium dioxide may be arranged so as to be in direct contact with the user, and may be provided to the user via a protective cloth such as a woven cloth, a nonwoven cloth, or a knit. You may come in contact.

The titanium dioxide used in the tourmaline-containing sheet of the present invention is preferably anatase type titanium dioxide. Such titanium dioxide is widely marketed by Kobe Steel and others.

Further, the tourmaline-containing sheet of the present invention may contain ferrite or polyphenol as a third component in addition to the above-mentioned tourmaline and titanium dioxide. Ferrite that is magnetized is preferable. Preferred polyphenols are tea polyphenols and catechins.

[0018]

【Example】

 FIG. 1 shows an example A of a tourmaline-containing sheet according to the present invention. In this figure, the inside is shown partially.

Tourmaline obtained by dispersing tourmaline powder and anatase type titanium dioxide powder (both having an average particle size of 10 μm, titanium dioxide powder manufactured by Kobe Steel) in a polyester resin on a base sheet made of a woven cotton fabric. And titanium dioxide are coated in a polka dot shape having a diameter of 2 cm 2 (hereinafter, this layer is referred to as “coating layer”). The basis weight of tourmaline and titanium dioxide is 30 g / m ² with respect to the entire sheet.

Further, a protective sheet made of a cotton woven fabric is superimposed on the protective sheet by a sashimi-shaped stitch, so that the entire sheet is a single flexible sheet (FIG. It is shown).

For comparison, a sheet B prepared in exactly the same manner as the above-mentioned tourmaline-containing sheet A except that it did not have titanium dioxide, and a sheet prepared exactly as the above-described tourmaline-containing sheet A except that it did not have tourmaline. C, a sheet D having neither titanium dioxide nor tourmaline were prepared, and the following examination was performed as bedding.

That is, from April to May, the above four types of sheets were handed over to a total of 14 persons, each of seven monitors and men and women of the age group of 40 to 60 years old. I got to sleep between the beds or between the bedsheet and the bed pad. Each monitor was tested without knowing the details of each sample.

Table 1 shows the number of persons who were able to sleep well and were completely tired as a result of examining whether or not they could sleep well.

[0024]

[Table 1]

From Table 1, it can be seen that when the tourmaline-containing sheet A according to the present invention is used as bedding, the effect of sleep is high and the effect lasts.

Furthermore, 10 people who snore on a daily basis were used at bedtime using the sheets A to D prepared in the same manner, and the presence or absence of snoring for 10 minutes from 1 hour after going to bed using a tape recorder Was examined. Table 2 shows the number of people who snore out of these 10 people.

[0027]

[Table 2]

According to Table 2, when the tourmaline-containing sheet A according to the present invention is used as bedding, a user can sleep well, and as a result, even a person who normally snores can go to bed with almost no snoring. You can see that.

[0029] Similar to sheet A above, except that ferrite is added to the coding layer together with tourmaline and titanium dioxide and further magnetized (sheet E), and catechin is added to the coding layer together with tourmaline and titanium dioxide. A sheet (sheet F) to which the film was added was prepared, and a monitor test was similarly performed. Table 3 shows the number of monitors that could sleep well at this time.

[0030]

[Table 3]

From Table 3, it can be seen that these sheets E and F can obtain a higher sleep effect than the combined sheets of tourmaline and titanium dioxide. Furthermore, in addition to this, many monitors commented that sheet F did not attach body odor (sweatiness) to bedding even after one week of use, and it was recognized as significant.

In the above embodiment, an example was shown in which the tourmaline-containing sheet of the present invention was used as a mattress. However, the present invention is not limited to this example, and other examples include a futon cotton bag, a pillow, a blanket, or wallpaper, It can be used for various purposes in fields where seats are used, such as shoulder pads for clothes and underwear.

When the sheet A is processed and used as a shoulder pad, the higher shoulder stiffness prevention effect is maintained for a longer period of time than when the sheet B is similarly used as a shoulder pad. Has been confirmed as a result of a monitor test.

[0034]

[Effect of the invention]

 The tourmaline-containing sheet of the present invention is an excellent tourmaline-containing sheet in which the excellent effects of tourmaline are maintained for a long time.
