The present invention relates to a method of manufacturing a planar heating sheet having excellent far-infrared and anion emission characteristics, and a planar heating sheet prepared by the method, and a planar heating sheet with improved emission properties,

The present invention relates to a method of manufacturing a sheet-like heat generating sheet having excellent far-infrared and anion release characteristics, and to a sheet-shaped heat-generating sheet produced thereby. More particularly, the present invention relates to a sheet- The present invention relates to a technique for manufacturing a sheet-like heat-generating sheet excellent in health-promoting effect by dramatically improving far-infrared and anion release characteristics.

A fiber prepared by coating carbon fiber on a fiber yarn (hereinafter referred to as carbon fiber) can be used as a heat generator because it generates resistance when electricity is applied. Because of the high electrical resistance characteristics of the weave fabric using this carbon fiber yarn as a heating yarn, the temperature can easily be raised to a desired temperature in a short time. Unlike an electric mat using an existing heating wire, a DC power source is used, And has a constant temperature characteristic that no longer increases in temperature when a certain temperature is reached, so that it can be minimized in electric power consumption and there is no fear of burns, and thus it has recently attracted high interest as a health material.

In addition, such carbon fiber is used as a heating plate, a heating mat, a heating wall material, a heating sheet, a heating line, a mountain climbing or health clothing, and a bedding material since the carbon powder is used to radiate far- There is a growing interest in new materials that can replace conventional electric mats and heat transfer mechanisms.

However, in the case of an exothermic mat using carbon fiber yarn, it is hardly seen to emit a far-infrared ray to enhance the vitality of the human body, as is known when the far-infrared ray emission characteristic is actually evaluated. Existing carbonaceous heating mats do not emit electromagnetic waves, but they have good health effects. However, they do not have the effect of enhancing human body vitality because they have far infrared rays and negative ion emission characteristics.

Accordingly, many techniques have been developed and proposed to improve far-infrared and anion emission characteristics by containing a material having far-infrared rays and anion emission characteristics in fibers or fabrics.

As described above, various technologies have been proposed to improve the functions of fibers, textiles or plastic products using natural ceramic materials having far-infrared and anion emission characteristics, but they have been applied to heat mats using carbon fiber yarns Technologies to improve are not yet developed or proposed.

The present invention has been developed in consideration of the circumstances of the prior art as described above, and it is an object of the present invention to provide a carbonaceous heat-generating sheet using carbon yarn, The present invention provides a technique of further applying a natural stone powder having excellent far infrared ray and anion release property to complement the present invention.

The method of manufacturing the planar heating sheet according to the present invention and the advantages and advantages of the planar heating sheet produced by the method will be described below.

1. First, in the case of a heating mat using a conventional AC power source, a large amount of electromagnetic waves are generated and harmful to the health of the user. Therefore, there has been a problem that consumers avoided using the heating mat. And the DC power is supplied through the DC regulator to generate heat, so that no electromagnetic waves are generated, so that it is not detrimental to health by itself, so that the consumer can use it safely.

2. On the other hand, products that have been marketed as exothermic mats using carbon fiber have been promoting that far-infrared rays and negative ions are emitted. However, there is a limitation in that the amount of far-infrared rays and anions emitted is insufficient, By using the natural stone powder having excellent far infrared ray and anion emission characteristic, the far infrared ray and anion emission amount can be remarkably increased as compared with the heat mats using conventional carbon yarn.

3. Also, in the case of natural stone powder having excellent far infrared ray and anion emission characteristic used in the present invention, there have been developed techniques for applying it to a fiber or a fabric in the past, but the adhesion to the fiber is poor and the fastness is low. This problem is solved by a method of fiberizing natural stone powder and woven and then coating the surface.

In addition, in the case of the exothermic mat using the carbon fiber yarn, when the mat is manufactured using the carbon fiber yarn, a spark is generated at the portion where the carbon yarn and the coating surface are joined, frequent yarn splicing occurs, In the present invention, the problem of spark generation can be completely solved by using a thermocompression bonding method without applying a conventional adhesive method in coating a woven fabric with a polymer film.

5. Since the natural stone powder coating yarn used in the present invention is similar to the conventional carbon fiber manufacturing process, a carbon fiber coating device can be used as it is without requiring a separate manufacturing device, so that it is easy to manufacture, There are also advantages.

The method for manufacturing the sheet heat generating sheet according to the present invention has the following five steps.

That is, a fiber preparing step (first step) for producing each fiber yarn used for weft yarns and warp yarns to produce a heat yarn using carbon yarn;

A fabric weaving step (second step) in which the prepared fiber yarns are included in weft yarns and warp yarns and carbon yarns and polar yarns are arranged to weave the heat generation fabrics;

A surface coating step (third step) in which a polymeric resin film is disposed on both upper and lower surfaces of the woven fabric; And

(Step 4) of cutting the surface-coated fabric, connecting the power source,

Hereinafter, the above steps will be described in detail for each step.

(1) Step 1: Preparation of fibers

This fiber preparing step is a step of manufacturing each fiber yarn to weave the fabric.

The fiber yarn produced in this step is carbon yarn and natural stone powder-coated yarn, and the natural stone powder-coated yarn mainly includes pegmatite-coated yarn, apatite-coated yarn and tourmaline-coated yarn, and further includes rare earth natural stone coated yarn.

In the present invention, such fiber yarn can be produced by repeating the process of impregnating and drying the yarn into the coating solution liquid several times, preferably one to three times, and the surface can be smoothly gathered by rotating the surface of the roller in a repeated process.

The carbon stock solution used in the present invention is prepared by mixing 5 to 30% by weight of a carbon powder having a particle size of 0.01 to 10 탆 and 0.1 to 10% by weight of a conductive filler, 50 to 70% by weight of a solvent, 10 to 30% And the remaining amount of the additive is preferably used. At this time, when the carbon powder has a particle size of 0.01 to 0.1 탆 and a particle size of 1 to 10 탆, the carbon powder can lower the resistance value and is more effective. As the conductive filler, an inorganic substance such as magnesium oxide and silicon carbide can be used. As the solvent, a solvent capable of dissolving the binder resin and the additive is preferably methyl ethyl ketone (MEK), dimethyl formamide (DMF), toluene and the like Can be used.

As the binder resin, a polyurethane resin or a polyacrylic resin can be used.

As additives, dispersants, plasticizers, coupling agents, antifoaming agents, antioxidants and the like can be used.

The process of impregnating and drying the carbon fiber thus formed with the fiber yarn is carried out one to three times to obtain carbon yarn. The thickness of the carbon coat in the obtained yarn is preferably in the range of 0.1 to 100 mu m.

The yarn fibers used in the present invention may be either natural fibers or synthetic fibers. The natural fibers are preferably cotton fibers, and the synthetic fibers are preferably polyester, nylon, or acrylic fibers.

In addition, a natural stone powder coated yarn is produced by a method similar to the carbon fiber manufacturing method.

First, a pegmatite-coated yarn is prepared, which comprises 1 to 20% by weight of a pegmatite pulverized material having a particle size of 0.01 to 1.0 탆, 50 to 85% by weight of a solvent, 10 to 30% by weight of a binder resin, The pegmatite paste is impregnated with a yarn and dried for 1 to 3 times. The solvent, the binder resin and the additive used at this time may be the same or similar to those used in the carbon fiber manufacturing process.

Pegmatite is also known as gigantic granite as a differentiated ore product of magma, and ores that can act as pharmacological agents as colored radioactive substances are called gingitoge pegmatite in particular. These pegmatites contain 9 kinds of components useful for human body among 20 kinds of constituents, and are known to have effects such as far-infrared radiation, antimicrobial deodorization, smack and electromagnetic wave shielding. Therefore, many techniques for manufacturing functional products using these characteristics have been proposed, and many related patents exist. (Korean Patent No. 506691, No. 426789, No. 08655117, No. 0726162, Korea Utility Model No. 0416154, etc.) The present invention provides a special method for utilizing the characteristics of pegmatite, A pegmatite-coated yarn is impregnated into a yarn and dried to prepare a pegmatite-coated yarn.

Also, an apatite coated yarn is produced as a natural stone powder coated yarn.

The apatite coating yarn was impregnated with apatite paste containing 1 to 20% by weight of an apatite finely ground product having a particle size of 0.01 to 1.0 탆, 50 to 85% by weight of a solvent, 10 to 30% by weight of a binder resin, The drying is carried out several times, preferably one to three times.

The solvent, the binder resin and the additive used at this time may be the same or similar to the components used in the carbon fiber and pegmatite-coated yarn.

Apatite, depending on the components as a form of phosphate mineral OH ^- are Many hydroxyapatite, Cl ^- are Many chloro apatite, F ^- referred to as the apatite as many are fluoro, and even with a lot of other silicate, carbonate, sulfate, . Among them, hydroxyapatite is a major component of enamel quality of teeth, and it is known that it is contained in many bones. The hydroxyapatite is a basic calcium phosphate having the chemical formula Ca ₁₀ (PO ₄ ) ₆ (OH) ₂ , which is similar to the inorganic component of bone or teeth of a human body, and has excellent biocompatibility and bioactivity. In other words, it is not biocompatible and promotes bone induction at the interface. Therefore, it is a typical biomaterial which is widely used as a coating material for hard tissue implant materials and metal implants.

Such an apatite is also an important characteristic that the generation rate of anions is significantly higher than that of the conventional anion generating materials such as jade, loess, and charcoal, and the far infrared ray emissivity is also high, so that it can be used as a health auxiliary device or a medical device. There have been many proposals for producing functional products using the characteristics of apatite, and there are many related patents. (Korean Patent No. 1133912, No. 0481189, etc.) The present invention provides a special method for utilizing the properties of the apatite. The method comprises impregnating a yarn with apatite paste by using a method similar to the method for producing carbon yarn, To produce apatite coated yarn.

Also, a tourmaline coated yarn is produced as a natural stone powder coated yarn.

The tourmaline coating yarn is impregnated with a tourmaline paste containing 1 to 20% by weight of tourmaline finely divided particles having a particle size of 0.001 to 0.5 탆, 50 to 85% by weight of a solvent, 10 to 30% by weight of a binder resin and a residual additive Drying is carried out 1 to 3 times. Tourmaline powder is not easy to bind because it has very poor affinity with polymeric binders and yarn fibers. Therefore, in the present invention, only nano-sized particles having very small particle size should be selected and used. Therefore, in order to produce nano-sized particles, it is preferable to perform pulverization using an ultrasonic pulverizer. The solvent, the binder resin and the additive used in the preparation of the tourmaline coated yarn in the present invention may be the same or similar to those used for the carbon yarn and the pegmatite coated yarn.

Tourmaline is a kind of igneous rock which has a hexagonal crystal structure. It is a complex borosilicate of aluminum, iron, magnesium, alkali metal, etc. and aluminum. It is one of the minerals that scatters energy by itself such as uranium or magnetite and emits far infrared rays and anions Is known as a healthy gem that gives vitality to the human body. In particular, the positive and negative electrodes are present at both ends of the tourmaline crystal, and a weak current of about 0.06 mA flows permanently, which is also called tourmaline. These electrical properties of tourmaline stimulate the human acupuncture points to improve the peripheral circulation system and promote blood flow, which is effective for hypertension and plaque disease. The far infrared rays are emitted in a large amount and the cells are activated to improve the constitution and improve the blood purification And it stimulates blood circulation and metabolism, so it relieves fatigue, gastrointestinal activation, pain, insomnia and coldness, and generates a large amount of anion by electrolysis in contact with water, and it has antibacterial, deodorizing, cleaning effect, It improves the constitution to a weakly alkaline constitution and gives a sense of stability to the human body, and also serves to neutralize harmful electromagnetic waves generated from various electric and electronic products.

Many techniques for producing functional products using such properties of tourmaline have been proposed, and many related patents exist. (Korean Patent No. 0883173, No. 0465522, Korean Patent Publication No. 2002-0062908, etc.) The present invention provides a special method for utilizing the properties of tourmaline, Tourmaline coated yarn is prepared by impregnating yarn with tourmaline paste and drying it.

Further, in the present invention, a rare earth natural stone coated yarn optionally using rare earth natural stone powder may be additionally used.

Rare earth natural stone is known to be effective in promoting cell metabolism, promoting vitality, clearing blood, restoring nervousness and fatigue, and promoting food by releasing a large amount of negative ions.

Examples of the rare earth natural stone that can be used in the present invention include at least one selected from strontium, vanadium, zirconium, cerium, nepheline, lanthanum, barium, rubidium, cesium and gallium, A process for impregnating and drying a rare earth natural stone paste containing rare earth natural stone powder having a particle size of 1 to 20% by weight, a solvent of 50 to 85% by weight, a binder resin of 10 to 30% by weight, 3 times to prepare a rare earth natural stone coated yarn. The solvent, the binder resin and the additives used in this case may be the same as or similar to the materials used in the carbon fiber manufacturing process.

(2) Step 2: Fabric Weaving Step

The carbon yarn, the pegmatite-coated yarn, the apatite-coated yarn and the tourmaline-coated yarn prepared in the first step are weighed as a set together with the yarn fibers.

That is, the carbon yarn, the pegmatite-coated yarn, the apatite-coated yarn, the tourmaline-coated yarn, and the yarn fiber are designed to be fed as weft yarns in a single set and the weft yarns are weaved, The fabric is manufactured by including the poles at a certain distance from the surface.

The carbon yarn, the pegmatite-coated yarn, the apatite-coated yarn, the tourmaline-coated yarn, and the yarn fiber may be continuously supplied by one strand or continuously supplied by two or more strands, and the order thereof is not particularly limited, .

In addition, the fiber supplied in the weft direction may further include a rare earth natural stone coated yarn produced in the first step in addition to the carbon yarn, the pegmatite coated yarn, the apatite coated yarn, the tourmaline coated yarn and the yarn fiber.

In addition, in the step of weaving the fabric in this step, functional fibers other than the yarn can be manufactured in the warp direction as well as the warp direction. That is, the pegmatite-coated yarn, the apatite-coated yarn and the tourmaline-coated yarn except for the carbon yarn and the yarn fibers can be weft-knitted together as a set, and optionally the rare earth natural stone coating yarn obtained in the first step can be further woven have.

The fabric thus woven can be supplied with electric power through the polar line, and electric energy is converted into thermal energy through the carbon fiber yarn to generate heat, and the electric power supplied through the polar line uses DC power, so that there is an advantage that no electromagnetic wave is generated.

(3) Step 3: Surface coating step

A polymeric resin film is disposed on the upper and lower surfaces of the fabric obtained in the second step, followed by hot pressing to coat the surface.

Conventionally, in order to coat the polymeric resin film on the surface of the fabric, a method of attaching the polymeric resin film to the fabric by using an adhesive agent on the attachment surface of the polymeric resin film is used. However, when such an adhesive agent is used, the adhesive agent is hardened and leaves a fine powder. A spark (flame) is generated, and the fabric is burnt and the carbon yarn is cut off, so that a problem of not generating a smooth heat is found.

Therefore, in the present invention, a method of coating both surfaces by heat pressing without using an adhesive is used.

The natural stone powders used in the present invention are adhered to the yarn fibers by the binder resin. However, since the yarn fibers can be separated from the yarn fibers after a lapse of time and frequent friction occurs, the two sides of the fabric are coated with a polymer resin film . As the polymer resin that can be used at this time, a rubber type or a synthetic resin type can be used. As concrete examples, it is preferable to use PVC, PE, PET, silicone, urethane and the like with good warping property, weather resistance and durability after curing. It is preferable that the coating thickness is coated to a minimum thickness so as to sufficiently exhibit stretchability of the fabric and prevent the crushed natural stone from being desorbed.

(4) Step 4: Production stage

The surface-coated fabric obtained in the third step is cut to a desired size, the power is connected to the polarities formed at both ends, and the upper surface and the lower surface of the fabric are sewn together with the surface paper.

At this time, the power is supplied through the DC regulator, and the DC regulator can detect the temperature in the temperature sensor attached to the product and set the desired temperature. The sheet heating sheet according to the present invention is characterized in that electromagnetic wave is not generated because DC power is supplied by a DC regulator, not by supplying AC power as a general household power source. Therefore, it is possible to prevent the problem of generation of electromagnetic waves, which is a problem in the heating mat using the conventional AC power source.

Although the process for producing the sheet-like heat-generating sheet according to the present invention has been described in detail, the scope of the present invention includes not only the method for producing the sheet-like heat-generating sheet but also the sheet-

Therefore, the sheet-like heat-generating sheet according to the present invention

A carbon fiber yarn is weighed on the weft yarn, and a polymer yarn is coated on both sides of the weft-fabricated weft yarn with a certain distance from both ends in an oblique direction, and the electrode is connected to a power source, Wherein the carbon yarn, the pegmatite-coated yarn, the apatite-coated yarn, and the tourmaline-coated yarn and the yarn fibers prepared in the first step of the method for producing an area heating sheet of the present invention are assembled as one set And is woven as a weft yarn.

At this time, the weft set may further include the rare earth natural stone coated yarn manufactured in the first step of the method for manufacturing the sheet heat-generating sheet of the present invention.

The pegmatite-coated yarn, the apatite-coated yarn and the tourmaline-coated yarn except for the carbon yarn and the yarn fibers are produced as one set in the first step of the method for producing the surface heating sheet of the present invention, So as to be woven in a slope. At this time, the inclined set may further include the rare earth natural stone coated yarn manufactured in the first step of the method for producing the sheet heat generating sheet of the present invention.

Other aspects of the surface heating sheet according to the present invention are the same as those described above with respect to the method of manufacturing the surface heating sheet, and therefore, duplicated description thereof will be omitted.

The surface heating sheet manufactured according to the present invention is free from the generation of electromagnetic waves and is easy to manufacture, and the amount of far-infrared rays and negative ions emitted is significantly larger than that of the existing carbonaceous mats. Especially, when the heating mat is heated by supplying power, It is anticipated that medical effects such as anti-bacterial and deodorizing effect, promotion of user's metabolism, improvement of constitution, blood purification effect, fatigue recovery, induction of sleep, and health promotion are expected to be great.

Hereinafter, the present invention will be described in more detail by way of examples, but the scope of the present invention is not limited by the examples.
