Description

[Detailed Description of the Invention] The present invention relates to a core material for health bedding that accumulates negative electricity, and more specifically, it combines the excellent moisture absorption and sleeping comfort of textile materials and the excellent cushioning and stress absorption properties of plastic materials. This invention relates to a core material for bedding that combines the following and exhibits health effects due to negative electricity.

In recent years, as interest in health has increased, various health bedding products have been developed and proposed. One of these is the effectiveness of negative electricity on health, and bedding that utilizes this has also been proposed. There are various theories about the effect of negative electricity on health, but
In general, it has the effect of increasing cations such as calcium and potassium in the blood, making the blood slightly alkaline, and promoting blood flow. It is said to have a stimulatory effect.

By the way, there are still many aspects of the phenomenon and mechanism of charging that are unclear, but it is known from experience that charging tends to occur on either the positive or negative side, and this has been reported as the electrostatic series.
This makes it possible to qualitatively know the amount and polarity of static electricity generated.

The inventor of the present invention arrived at the present invention as a result of intensive research into bedding that can most efficiently store negative electricity and exert a spinal correction effect.

That is, the present invention is a composite board consisting of a hard board made of plastic foam and an elastic board that is softer and more elastic than the hard board, in which a breathable polyurethane foam board is superimposed on the surface of the hard board, and the surface is brought into contact with the human body. The core material for bedding is made by bonding to the surface a conductive nonwoven fabric made of a web belonging to the negative side of the electrostatic series and having a conductor disposed inside or on the surface.

As the plastic foam hard plate used in the present invention, polyethylene foam, polyvinyl chloride foam, etc., which belong to the negative side of the electrostatic series, are suitable.

By providing a plurality of protrusions on the surface of the hard plate, the acupressure effect due to the ridges and the ventilation effect due to the recesses can be exerted. Further, it is preferable to use a plate-like body having a plurality of consecutive semi-cylindrical shapes as the hard plate, since the same effect can be obtained.

Furthermore, if a plurality of wart-like protrusions are further provided near the top of the protrusion or semicylindrical shape, a fine acupressure effect is produced, which interacts with the larger acupressure effect of the semicylindrical protrusion or protrusion, and the delicate It has a strong acupressure effect. Furthermore, if ventilation holes are provided in the recesses between the semicylindrical shapes or between the protruding protrusions, air permeability can be further improved, and the pine tress can always be maintained in a sanitary manner.

As the elastic plate used in the present invention, polyurethane foam, foam rubber, etc. are suitable.

A hard plate and an elastic plate are made into a composite plate by joining means such as adhesion or welding. In this case, air permeability can be further improved by providing ventilation holes in the elastic plate that communicate with the ventilation holes provided in the hard plate.

The size, number, etc. of the aforementioned semicylindrical shape, protrusions, wart-like protrusions, and ventilation holes may be appropriately selected within a practical range.

As will be described in detail later, the breathable polyurethane foam board produces an air-breathing effect when the person turns over during sleep, and has the effect of maintaining the bedding (core material) in a sanitary condition. It is preferable to use a material whose surface has been profiled (processed into a small raised shape) to further improve air permeability.

In the present invention, the nonwoven fabric refers to all fabric structures having a mat-like structure such as felt, needle punch, tuft, and other webs joined by adhesive, mechanical bonding, binding, etc. The material for the nonwoven fabric may be feathers, natural fibers, or synthetic fibers, but polyacrylic, polyethylene, polyvinyl chloride, polyvinylidene chloride, polyester, etc. are particularly suitable because they are anionically charged. be.

As the conductor, carbon fibers, metal wires such as copper, aluminum, stainless steel, or alloys thereof, such as copper-cadmium alloys, copper-silver alloys, copper-tin alloys, etc., are used. Furthermore, conductive plastics in which fine particles of silver, carbon, copper, etc. are mixed with various plastic materials can also be used. The shape of the conductor is linear, net-shaped, band-shaped, chip-shaped, plate-shaped,
Examples include cloth-like shapes, but net-like or cloth-like ones are preferred, and particularly, ultrafine metal wire, carbon fiber nets, and carbon fiber cloth are preferred because they are comfortable to sleep on and can be folded freely.

The conductor is disposed inside or on the surface of the nonwoven fabric. When a base fabric is not used, it is arranged approximately inside or on the surface of the nonwoven fabric. When installing near the surface,
By burying the conductor to the extent that it is completely covered with the web, the comfort and aesthetics of the bed will not be affected. On the other hand, if a base fabric is used, it may be placed near the base fabric. In this case, a conductor made of an ultrafine metal wire or a carbon fiber net is particularly preferred. Alternatively, a metal wire may be wound around the base fabric. Furthermore, a base fabric made of twisted yarn in which ultrafine metal wires or carbon fibers are embedded may be used.

When the conductor is linear, net-shaped, etc., the arrangement density depends on the thickness of the conductor, desired conductivity, etc., but is preferably about 5 to 20 conductors per 10 cm ² . If the density is too large, the probability that the needles will collide and break through the conductor will increase. On the other hand, if it is too small, the conductivity will decrease. Further, the conductor is provided on the entire surface or a part thereof.

The conductive nonwoven fabric, the breathable polyurethane foam board, and the composite board are each placed in an inner bag, or the inner bag is omitted and stored directly in an outer bag to make bedding. It is preferable to use fiber bags belonging to the negative electricity side as the inner bag and the outer bag. Of course, the bedding made of the core material of the present invention can be used as a single sheet, divided into two sheets, divided into three sheets, etc. In the case of split types such as two-piece or three-piece bedding, each piece of bedding should be attached side by side with magnets, double-sided adhesive tape, fasteners, buttons, "Magic tape (registered trademark of Velcro)," or inside an integrated cover. It should be accommodated in

In the bedding core material of the present invention, the conductor inside or on the surface of the nonwoven fabric functions as an antistatic agent, so it effectively accumulates and retains the negative electricity generated in the surrounding nonwoven fabric, allowing it to accumulate on or under the fibrous structure. By lying down, you can fully enjoy the effects of negative electricity. If a power source is connected to the nonwoven fabric so that it can be energized, the effect of accumulating and retaining negative electricity can be further enhanced, and the effects of negative electricity can be enjoyed even more effectively.

Furthermore, by connecting a negative electricity generating device to the core material of the present invention, it is possible to further utilize the health effects of negative electricity. Any known negative electricity generating device can be used, and negative electricity is generated continuously or intermittently using a timer and is stored and stored. The negative electricity generator is preferably connected to a nonwoven fabric that has a large negative electricity accumulation space and is in direct contact with the human body.

A more important feature of the present invention is that a breathable polyurethane foam board is interposed between the conductive nonwoven fabric and the composite board. In other words, because conventional fiber (cotton) futons are used on a flat surface such as a tatami mat or bed, there is no space between the futon and the tatami mat or bed, and even when you turn over, there is no air circulation. is almost zero. Sweat and waste products emitted from the human body are absorbed by the futon, travel down the fibers, and reach the interface between the futon and the tatami mat or bed, where ventilation is blocked and the salt content remains. It is deposited as water containing water and waste products. If you leave your futon covered for several days during the rainy season, the tatami mats and beds will become wet and mold will grow, which is a common experience in everyday life.

According to the present invention, the conductive non-woven fabric is always in contact with the breathable polyurethane foam board, and through this, the conductive non-woven fabric is in contact with the protruding ridges and semi-cylindrical shapes having concave portions through which air can freely flow, resulting in extremely good air permeability. Every time you toss and turn during sleep, your sleep is significantly enhanced by the synergistic action of the protrusions, the semicylindrical depressions, and the ventilation holes. Therefore, it is kept in a substantially completely dry state.

Hereinafter, the present invention will be described based on drawings showing embodiments.
