Description

The present invention relates to a fabric having a hydrogen generating function and a method for producing the same. In particular, a cloth having a hydrogen generation function, which is the most suitable material for a cloth or the like constituting a mask or the like and can quickly and continuously generate hydrogen in response to moisture invading from the outside or moisture existing in the surroundings such as exhaled breath, and the cloth thereof. Regarding the manufacturing method.

In recent years, attention has been paid to the efficacy based on the addition of reducing property when hydrogenated to water or the like, and its application to sanitary products has been proposed.
For example, a hygiene product has been proposed in which the hygiene product has an antioxidant function so that the hygiene condition can be improved when the product is worn on the human body (see Patent Document 1).
More specifically, by contacting metallic magnesium, mineral substances such as calcium, hydrogen generating substances formed by firing, and secretions or excretions from the human body, they react with water contained therein. Hygiene products that generate hydrogen gas (emergency adhesive plasters, sweat pads, sanitary products, mouth and nose masks, face masks).

Further, in order to supply hydrogen to a fuel cell or the like, a sheet-like hydrogen generator having good handleability, gradually advancing the reaction with the reaction solution, having a constant hydrogen generation concentration, and having a high reaction rate is also available. It has been proposed (see Patent Document 2).
More specifically, on a water-absorbent sheet made of a water-absorbent non-woven fabric or the like, a hydrogen-generating layer formed by blending a hydrogen-generating agent such as magnesium hydride in a resin, and a hydrophobic porous film are sequentially formed. It is a sheet-like hydrogen generating agent provided.

Further, a hydrogen generating material capable of generating hydrogen for a long period of time in contact with water has also been proposed (see Patent Document 3).
More specifically, a pressure-sensitive adhesive sheet in which a hydrogen generating agent such as metal hydride particles is blended in a non-aqueous base such as polystyrene resin and has adhesiveness, and protection having no water permeability. A hydrogen generating material containing a film.

On the other hand, a hydrogen suction method that can efficiently suck hydrogen gas from the respiratory system has also been proposed.
More specifically, as shown in FIG. 8, the electrolytic solution in the hydrogen gas generating container 103 is electrolyzed by the electrode 106 connected to the power source 108 to generate hydrogen gas.
Next, the generated hydrogen gas is sucked from the suction tube 123 into the suction mask 124 that covers the mouth and nose as the suction device 125 through the water cup 118, that is, the hydrogen gas is taken into the body from the respiratory system. This is a hydrogen suction method.
Then, according to the hydrogen suction method, the suction device 125 can secure sufficient oxygen for the suction person by introducing the air necessary for breathing from the air inlet into the suction mask 124. Become.

WO2015 / 137242 (Claims, etc.) JP-A-2009-249235 (Claims, etc.) Japanese Unexamined Patent Publication No. 2013-189379 (Claims, etc.) JP-A-2015-217116 (Claims, etc.)

However, in the sanitary products disclosed in Patent Document 1, for example, in a mask for mouth and nose, it is unclear how the hydrogen generating substance is immobilized, and how it reacts with water to be stable. There was a problem that hydrogen was generated in the body and absorbed into the body, or was not intended at all.
Further, the sheet-shaped hydrogen generating agent disclosed in Patent Document 2 also has the main purpose of supplying hydrogen in a fuel cell, and there is no description or suggestion regarding a mask for mouth and nose, and therefore, a mask for mouth and nose, etc. There was a problem that it was not intended to be applied to.
Further, also with respect to the hydrogen generating agent disclosed in Patent Document 3, it is difficult to uniformly mix the hydrogen generating agent in a non-aqueous base such as polystyrene resin, and how to use the hydrogen generating agent in a mask for mouth and nose. It is unclear how to immobilize hydrogen, and there is a problem that it is not intended how to react with water to stably generate hydrogen and absorb it in the body.

On the other hand, the hydrogen suction method using a predetermined suction mask or the like disclosed in Patent Document 4 covers the mouth and nose of the suction device as a suction device by passing hydrogen gas generated by the electrolyzer through a water cup. It was necessary to have the suction mask suck from the suction tube.
Therefore, as a whole, there is a problem that the suction device tends to be large and difficult to carry.
In addition, such a hydrogen suction method has a problem that the electrolyzer of the electrolytic solution is also an indispensable constituent requirement in order to efficiently generate hydrogen, which increases the cost and is economically disadvantageous. ..

Therefore, as a result of diligent efforts by the inventors of the present invention, a predetermined hydrogen generating agent-containing resin is patterned and printed on the surface of the cloth without using an electrolyzer or the like, so that contact with water or water vapor is uniform. As a result, it has been found that not only hydrogen can be generated quickly and continuously, but also the flexibility of the fabric is not impaired, and the present invention has been completed.
That is, the fabric or the like constituting the mask or the like has a patterned hydrogen generation layer capable of efficiently and continuously generating hydrogen in response to surrounding moisture, exhaled breath, etc. while maintaining flexibility.

It is possible to provide a fabric having a simple structure and an inexpensive hydrogen generating function capable of generating hydrogen.
More specifically, a resin containing a predetermined hydrogen generating agent (including a hydrogen generating agent-containing resin layer) is partially provided on the surface of the cloth or the like to form a patterned hydrogen generating layer. As a result, while ensuring the passage of water and water vapor, the contact between these and the hydrogen generating agent becomes uniform, and a predetermined amount of hydrogen can be generated quickly, continuously, easily and inexpensively, and also the cloth.

By controlling the shape and the equivalent circle diameter (width) of the hydrogen generating agent-containing resin in this way, not only the contact with water and water vapor is made uniform, but also the flexibility of the fabric is improved. Can be well-balanced.
The dot-shaped or line-shaped hydrogen generating layer does not necessarily have to be uniformly patterned on the fabric.
For example, if the cloth with a hydrogen generating function is a sanitary mask, the number of dot-shaped or line-shaped hydrogen-generating layers in the mouth, nose, and the vicinity thereof is relatively large, while other than that, the number of dots or lines is relatively large. Rather, it is also preferable to reduce the number of hydrogen generating layers relatively.

Further, in constituting the hydrogen generating function fabric of the present invention, the presence area of the hydrogen-generating layer, unit area 100 cm ² per fabric, it is preferably set to a value within the range of 1~95cm ^2.

However, in the case of a sanitary mask or the like, the existing area of the hydrogen generating layer does not necessarily have to be constant on the entire surface or all the constituent parts. It is also preferable that the area is 50 to 95%, and other than that, the value is less than 50%.

Further, in constructing the cloth with a hydrogen generating function of the present invention, the content of the hydrogen generating agent in the hydrogen generating agent-containing resin is set to a value within the range of 0.1 to 100 parts by weight with respect to 100 parts by weight of the resin. Is preferable.
By controlling the blending amount of the hydrogen generating agent in this way, the amount of hydrogen generated per unit time, the hydrogen generation time, and the like can be easily controlled within a desired range.
However, in the case of a sanitary mask or the like, the content of the hydrogen generating agent does not necessarily have to be constant on the entire surface or all the constituent parts. It is also preferable that the amount is 20 to 80 parts by weight with respect to 100 parts by weight of the resin, and other than that, the value is less than 20 parts by weight.

Further, in constructing the cloth with a hydrogen generating function of the present invention, it is preferable that the cloth is at least one of non-woven fabric, woven cloth, gauze, bandage, and felt.
By limiting the type of fabric in this way, the hydrogen generating agent can be fixed relatively easily, and good flexibility can be obtained while securing a passage for water and water vapor.

In constructing the cloth with a hydrogen generating function of the present invention, when the above-mentioned cloth is used as the first cloth, the front surface and the back surface of the first cloth, or one of them, is used as a second cloth. It is preferable that the fabrics of the above are laminated.
By laminating different fabrics in this way, the hydrogen generating agent can be fixed in a sandwich shape between the laminating of a plurality of fabrics, and it is easy to control the permeability of water and water vapor and the flexibility of the entire fabric. Can be.

In constructing the cloth with a hydrogen generating function of the present invention, it is preferable that the cloth is processed into a sanitary mask.
By being processed into a sanitary mask in this way, it is possible to quickly and continuously generate a predetermined amount of hydrogen by reacting with not only the moisture entering from the outside but also the exhaled breath, and by extension, it has a simple structure and An inexpensive cloth with a hydrogen generating function can be provided.

Another aspect of the present invention is a method for producing a fabric having a hydrogen generating function and having a patterned hydrogen generating layer, which is derived from a hydrogen generating agent-containing resin containing at least a hydrogen generating agent and a resin, and is described in the following steps ( It is a method for producing a cloth having a hydrogen generating function, which comprises 1) to (3).

1. 1. Cloth A cloth used for a cloth having a hydrogen generating function is a broad concept including a fiber material, and is typically a fiber member including any of a woven cloth, a non-woven fabric, gauze, felt, a perforated fiber sheet, and the like.
In addition, the thickness and shape of the fabric, the outer shape, and the like can be appropriately changed depending on the application.
Therefore, it is usually preferable that the thickness of the fabric is in the range of 0.01 to 10 mm and the outer shape is rectangular, square, circular, oval, irregular, or the like.
Further, it is also preferable to roll the cloth with a hydrogen generating function in order to efficiently manufacture a processed product using the cloth with a hydrogen generating function, for example, a sanitary mask.
In that case, it is usually preferable to use a long roll having a width of 10 cm to 200 cm and a length of 1 to 100 m as the cloth.

Therefore, the type of resin constituting the fabric is not particularly limited, but for example, polyester resin, polyurethane resin, polyolefin resin (including acrylic resin), polyamide resin, polystyrene resin, polycarbonate resin, polyvinyl acetate resin. , Polyacetate cellulose resin and the like are preferably at least one kind.
Further, the fibers constituting the fabric are preferably synthetic fibers, natural fibers or blended fibers.
Furthermore, in order to improve breathability, a perforated or mesh-like cloth may be used, and in addition, in order to improve handling, durability, breathability, etc., a woven cloth, a non-woven fabric, and a resin sheet may be used. It may be a composite material with or the like.

Further, for example, in the case of the sanitary mask (type 1) 20 shown in FIG. 3A, a hard felt having a thickness of 0.5 to 5 mm is used as the cloth 10, and the cloth is deformed into a cup shape. It is preferably processed.
In the case of the sanitary mask (type 2) 20'shown in FIG. 3B, the cloth 10 is a rectangular gauze having a thickness of 0.1 to 5 mm, a length of 7 cm, and a width of 13 cm. It is preferable that a plurality of sheets (for example, 2 to 5 sheets) are laminated, and the right end and the left end are sewn in a bag shape, respectively, and the inside thereof is passed through an ear hook.

Further, in the case of the sock shown in FIG. 4, in the case of a cloth having a hydrogen generating function, a sock thread made of polyurethane fiber, polyester fiber, or the like is woven to manufacture the sock, and then the finger or heel is formed. , It is preferable to attach the cloth having a hydrogen generating function by using a urethane-based adhesive or a cellulose-based adhesive that easily adheres to sock fiber.
Therefore, in the case of socks, good elasticity and durability are required, and therefore, the same elasticity and durability are required for the fabric for the fabric with the hydrogen generation function.

Further, in the case of the cosmetic face mask 50 and its auxiliary parts 60 shown in FIGS. 5A to 5B, the fabric 10 includes a fiber layer containing a fiber material impregnating the cosmetic and evaporation of the cosmetic. It is preferable to use a composite sheet obtained by laminating a hydrophobic film for preventing the above.
A thermocompression bonding portion for partially laminating the fiber layer and the hydrophobic film is provided, and the hydrophobic film in the thermocompression bonding portion is provided with an opening penetrating toward the fiber layer. Is preferable.
The reason for this is that by constructing the cosmetic face mask in this way, appropriate adhesiveness, predetermined transpiration prevention property of cosmetics, good flexibility and shape followability can be obtained.

2. Hydrogen generation-containing resin (1) Hydrogen generator (1) -1 type 1
The type of hydrogen generating agent is not particularly limited, but for example, at least one of metallic magnesium, magnesium oxide, magnesium hydride, magnesium alloy, calcium hydride, aluminum, and magnesium / aluminum mixture is mainly used. It is preferably a component.
The reason for this is that by using this kind of hydrogen generating agent, predetermined hydrogen is generated by contact with water or water-like substances that invade from the outside, water vapor, exhaled breath, or the like. In this case, the amount of hydrogen generated per unit time, the hydrogen generation time, and the like can be easily controlled within a desired range.
In particular, if magnesium is the main component, it has the advantage that it has high reactivity with surrounding water, reacts rapidly with exhaled breath, and easily generates hydrogen.
Further, in the case of magnesium oxide, even when the particle size is set to a predetermined average particle size (for example, 1 μm or less), the risk of dust explosion is relatively low and it is easy to handle, but the reactivity with water is maintained. It has the advantage of being easy.
Furthermore, in the case of magnesium hydride or magnesium alloy, even when the particle size is set to a predetermined average particle size (for example, 1 μm or less), the risk of dust explosion is relatively low and it is easy to handle, while it is easy to handle with water. There is an advantage that the reactivity of is easy to sustain.

(1) -2 Type 2
Then, it is also preferable to add at least one such as metallic aluminum or a hydrogen storage alloy to a part of the hydrogen generating agent to adjust the amount of hydrogen generated per unit time, the hydrogen generation time, and the like.
That is, the blending amount of metallic aluminum, hydrogen storage alloy, etc. is preferably set to a value in the range of 0.01 to 30 parts by weight with respect to 100 parts by weight of metallic magnesium, which is the main component. The value is more preferably in the range of 10 parts by weight, and further preferably in the range of 0.5 to 5 parts by weight.

(1) -3 Non-hydrogen generating material coating Further, the periphery of the main components of the hydrogen generating agent such as metallic magnesium and magnesium oxide is coated with resin, ceramic, or the like as a non-hydrogen generating material coating. It is also preferable to coat with a non-hydrogen generating material of.
The reason for this is that by coating with a non-hydrogen generating material in this way, the reactivity between the hydrogen generating agent and water or the like can be controlled, and the aggregation of the hydrogen generating agent can be effectively prevented. Because.
Further, the alkaline component may elute from the inside of the hydrogen generating agent, and by coating with such a non-hydrogen generating material, such elution can be efficiently suppressed. ..
Therefore, the thickness of the non-hydrogen generating material coating is preferably set to a value in the range of 0.01 to 100 μm, more preferably set to a value in the range of 0.1 to 30 μm, and 0.5 to 10 μm. It is more preferable that the value is within the range.

(1) -4 Blending amount The blending amount of the hydrogen generating agent in the hydrogen generating layer is usually preferably set to a value in the range of 1 to 100 parts by weight with respect to 100 parts by weight of the resin.
The reason for this is that by controlling the blending amount of the hydrogen generating agent in this way, the amount of hydrogen generated per unit time, the hydrogen generation time, and the like can be easily controlled within a desired range.
More specifically, if the blending amount of the hydrogen generating agent is less than 1 part by weight, the amount of hydrogen generated per unit time may become excessively small, or the hydrogen generation time may become excessively short. be.
On the other hand, if the blending amount of the hydrogen generating agent exceeds 100 parts by weight, it becomes difficult to disperse it uniformly in the hydrogen generating layer, it becomes difficult to form it into a uniform thickness, and further, hydrogen This is because the generated layer may be easily peeled off from the surface of the fabric.
Therefore, the blending amount of the hydrogen generating agent is more preferably set to a value in the range of 2 to 50 parts by weight, and further set to a value in the range of 5 to 20 parts by weight with respect to 100 parts by weight of the resin. preferable.

(1) -5 Shape 1
Further, regarding the shape of the hydrogen generating agent, it is particulate (including not only spherical but also flaky and amorphous outer shapes), and the average particle size (average circle equivalent diameter) of the hydrogen generating agent is 0. The value is preferably in the range of 1 to 300 μm.
The reason for this is that by controlling the average particle size of the hydrogen generating agent in this way, not only the uniform dispersion of the hydrogen generating agent becomes easy, but also the amount of hydrogen generated per unit time, the hydrogen generation time, etc. can be set within the desired range. This is because it can be controlled more easily.
More specifically, if the average particle size of the hydrogen generating agent is less than 0.1 μm, the amount of hydrogen generated per unit time may become excessively small, or the hydrogen generation time may become excessively short. Is.
On the other hand, if the average particle size of the hydrogen generating agent exceeds 300 μm, it becomes difficult to disperse it uniformly in the hydrogen generating layer, it becomes difficult to form it into a uniform thickness, and further, hydrogen generation occurs. This is because the layer may be easily peeled off from the surface of the fabric.
Therefore, the average particle size of the hydrogen generating agent is more preferably set to a value in the range of 5 to 100 μm, and further preferably set to a value in the range of 10 to 50 μm.
In addition, in the case of gravure printing or the like, it is more preferable to set the average particle size of the hydrogen generating agent to a value within the range of 0.1 to 30 μm from the viewpoint of not damaging the gravure roll.
The average particle size of the hydrogen generating agent can be measured by an optical microscope or an image processing system according to JIS Z8901.

(1) -6 Shape 2
Regarding the shape of the hydrogen generating agent, when it is flaky, the average thickness of the hydrogen generating agent is set to a value within the range of 0.001 to 10 μm, and the average particle size when viewed in a plan view is 0.1. The value is preferably in the range of ~ 200 μm.
The reason for this is that by controlling the average thickness of the flaky hydrogen generating agent in this way, not only the uniform dispersion of the hydrogen generating agent becomes easy, but also the amount of hydrogen generated per unit time, the hydrogen generation time, etc. This is because the desired range can be controlled more easily.
More specifically, when the average particle size of the flaky hydrogen generating agent is within a predetermined range and the average thickness is less than 0.001 μm, it is difficult to stably produce or uniformly disperse in the resin. This is because the hydrogen generation time may become excessively short.
On the other hand, if the average thickness of the flaky hydrogen generator exceeds 10 μm, it becomes difficult to disperse it uniformly in the hydrogen generating layer, it becomes difficult to form it into a uniform thickness, and further. This is because the hydrogen generating layer may be easily peeled off from the surface of the fabric.
Therefore, the average thickness of the flaky hydrogen generator is more preferably set to a value in the range of 0.005 to 1 μm, and further preferably set to a value in the range of 0.01 to 0.5 μm.
The average particle size of the flaky hydrogen generator can be measured in a plan view according to JIS Z8901, and the average thickness of the flaky hydrogen generator is also according to JIS Z8901. It can be measured using a caliper, a micrometer, or the like.

(2) Resin The main component of the resin constituting a part of the hydrogen generating layer is not particularly limited, but for example, silicone resin, vinyl chloride resin, urethane resin, polyester resin, polyolefin resin (acrylic). Resins included), cellulose acetylate resins (including cellulose acetylate butyrate resins, cellulose acetylate propionate resins, etc.), polystyrene-based resins, polysilazane compounds, polyacetal resins (polyvinylbutylbutyral resin, polyvinylformal resin, etc.) Etc.), vinyl acetate resin, natural rubber, synthetic rubber (SBR, SBS, SEBS, SIS, etc.), epoxy resin, and phenol resin are preferably at least one.
The reason for this is that by using such a resin, it has a predetermined hydrogen permeability while suppressing the reaction during mixing and storage with a hydrogen generating agent, so that it can quickly and surely with water entering from the outside. This is because hydrogen generation can be sustained for a relatively long period of time while reacting.

In particular, a silicone resin or a polysilazane compound is a suitable resin in that it has good hydrogen permeability and water vapor permeability and is excellent in curing characteristics (thermosetting property and photocuring property).
Further, vinyl chloride resin, urethane resin, natural rubber, and synthetic rubber (SBR, SBS, SEBS, SIS, etc.) are particularly excellent in printing characteristics, durability, and adhesion to various substrates. It is a suitable resin.
Further, a polyester resin or a polystyrene-based resin is a suitable resin in that it is particularly excellent in printing characteristics, versatility, and mechanical strength.
Further, if it is a cellulose acetate resin or the like, not only is it excellent in transparency, but also there is little odor peculiar to the polymer, and uniform dispersion of the hydrogen generating agent is relatively easy. In addition, since cellulose acetate resin and the like are well compatible with polycarbonate resin and polyphenylene ether, good rigidity, impact resistance, or resistance to fabric can be obtained by blending 1 to 30% by weight of the total amount. Adhesion can be improved.

Further, a polyolefin resin (including an acrylic resin) not only has excellent transparency, but also has a relatively low water content, can suppress a reaction with a hydrogen generating agent during storage, and has printing characteristics. It is a suitable resin because it has good dispersibility of a hydrogen generator and a hydrogen generator, and is relatively inexpensive.
That is, if it is a polyolefin resin (including an acrylic resin), good printing characteristics (screen printing characteristics, etc.) can be obtained, and even after the printing layer is formed, the periphery of the hydrogen generating agent is coated. This is because it can be uniformly dispersed and more stable hydrogen generation becomes possible.
Further, epoxy resins and phenol resins are suitable resins because they are excellent in thermosetting property, photocurability, etc., and also excellent in mechanical strength, durability, and adhesion to cloth. be.

In addition, it is also preferable to introduce a crosslinked structure by blending various crosslinking agents or utilizing self-crosslinking property in the resin constituting the hydrogen generating layer.
The reason for this is that by cross-linking the resin with various cross-linking agents, the amount of hydrogen generated can be controlled within a predetermined range, and the hydrogen-generating layer can be formed more firmly on the surface of the fabric or the like. ..

(3) Additive 1
Further, as one of the additives, it is preferable that at least one of a phosphate-based glass, a borosilicate-based glass, a carbonate compound, and a sulfite compound, which are water-soluble materials, is further blended.
The reason for this is that by further containing a water-soluble material (slightly water-soluble material) that gradually dissolves upon contact with water, pores are created inside the hydrogen generation layer, making it easier for water to permeate. This is because the amount of hydrogen generated per unit time, the hydrogen generation time, and the like can be more easily controlled within a desired range over a long period of time.

When such a water-soluble material is blended, the blending amount is preferably in the range of 1 to 100 parts by weight with respect to 100 parts by weight of the resin, and is in the range of 10 to 50 parts by weight. It is more preferable to set the value to.
The reason for this is that the amount of hydrogen generated per unit time, the hydrogen generation time, and the like can be more easily controlled within a desired range by setting the blending amount of such a water-soluble material.
More specifically, when the blending amount of the water-soluble material is less than 1 part by weight, the amount of hydrogen generated per unit time may become excessively small, or the hydrogen generation time may become excessively short. Because.
On the other hand, if the blending amount of the water-soluble material exceeds 100 parts by weight, it becomes difficult to uniformly disperse the hydrogen generating layer in the hydrogen generating layer, or it becomes difficult to form the hydrogen generating layer to a uniform thickness. Further, the hydrogen generating layer may be easily peeled off from the surface of the fabric.
Therefore, the blending amount of the water-soluble material is more preferably set to a value in the range of 10 to 80 parts by weight with respect to 100 parts by weight of the resin, and further set to a value in the range of 20 to 70 parts by weight. preferable.

(4) Additive 2
Further, in the hydrogen generation layer, as other additives other than the above-mentioned additive 1, an adhesive, a colorant, titanium oxide (concealing agent), an ultraviolet absorber, an antioxidant, a viscosity modifier, and an antistatic agent. It is preferable that at least one of the above is further blended.
The reason for this is that by blending such an additive, the functionality of the hydrogen generating layer can be further added or improved. In addition, since magnesium, which is a hydrogen generating agent, often changes to a black color, by adding a predetermined amount of a colorant or titanium oxide (concealing agent), the color becomes white as a whole and the appearance is significantly improved. be able to.
Therefore, when such an additive is blended, the blending amount is preferably a value within the range of 0.1 to 30 parts by weight with respect to 100 parts by weight of the resin, and is 0.5 to 20 parts by weight. The value is more preferably in the range of 1 to 10 parts by weight, and further preferably in the range of 1 to 10 parts by weight.

(5) Thickness Further, it is preferable that the thickness of the hydrogen generating layer is set to a value within the range of 1 to 2000 μm.
The reason for this is that by controlling the average particle size of the hydrogen generating agent in this way, not only the uniform dispersion of the hydrogen generating agent becomes easy, but also the amount of hydrogen generated per unit time, the hydrogen generation time, etc. can be set within the desired range. This is because it can be controlled more easily.
More specifically, if the thickness of the hydrogen generation layer is less than 1 μm, the amount of hydrogen generated per unit time may become excessively small, or the hydrogen generation time may become excessively short.
On the other hand, if the thickness of the hydrogen generating layer exceeds 2000 μm, it may be easily peeled off from the surface of the fabric, or it may be difficult to form a uniform thickness.
Therefore, the thickness of the hydrogen generating layer is more preferably set to a value within the range of 10 to 500 μm, and further preferably set to a value within the range of 20 to 200 μm.
The surface of the hydrogen generating layer is preferably substantially flat, but has surface irregularities of 0.1 to 20 μm as the center line average roughness (Ra) measured in accordance with JIS B 0651. It is also preferable.

(6) Laminating position The laminating position of the hydrogen generating layer 12 with respect to the fabric 10 is not particularly limited, but is usually FIG. 1 (a) to (b) or FIGS. 2 (a) to 2 (b). As shown in the above, the surface (single-sided or double-sided) of various fabrics is suitable.
That is, by forming the hydrogen generating layer on the surface of the fabric in this way, as shown in FIG. 1 (a), the moisture from the outside (A side) and as shown in FIG. 1 (b). In addition, there are more opportunities for contact with exhaled air that is discharged from the human body and invades from the inside (B side), and therefore a relatively large amount of hydrogen (H ₂ ) is released not only to the outside (A side) but also to the inside (A side). This is because it can be generated quickly and surely toward the B side).
Therefore, for example, in FIG. 1A, the water existing on the A side in the drawing reacts with the hydrogen generating layer 12 patterned on the A side of the cloth 14 with the hydrogen generating function, and becomes on the B side. , Shows the state of releasing the generated hydrogen.
Further, in FIG. 1B, the exhaled air existing on the B surface side in the drawing reacts with the hydrogen generating layer 12 patterned on the A surface side of the cloth 14 with the hydrogen generating function, and is generated on the B surface side. It shows the state of releasing the hydrogen.

On the other hand, as shown in FIG. 1C and the like, it is also preferable to laminate the hydrogen generation layer 12 between the plurality of fabrics (first fabric 10a and second fabric 10b).
The reason for this is that the hydrogen generation layer 12 is configured in this way to limit the amount of hydrogen generated, prolong the generation time, and further, the alkaline component is likely to elute from the hydrogen generation layer 12. However, this is because it is possible to effectively prevent the alkaline component from scattering to the outside (A-side and / or B-side).
Therefore, in FIG. 1 (c), the exhaled breath existing on the B-plane side in the drawing is a hydrogen generating layer existing in a pattern between the plurality of fabrics 10a and 10b constituting the cloth 14 with the hydrogen generating function. It shows a state in which it reacts with 12 and releases the generated hydrogen to the B surface side.

(7) Dot shape / line shape The shape of the patterned hydrogen generation layer 12 is not particularly limited, but is, for example, FIG. 2 (b) or FIGS. 3 (a) to 3 (b). Further, as shown in FIG. 4 and the like, it is preferable to provide the hydrogen generating layer 12 on the surface of the cloth 10 in the form of dots, lines, or one of them.
The reason for this is that by providing a hydrogen generation layer such as a dot shape, not only can it be formed easily and accurately by a printing method or the like, but also good air permeability can be obtained, the amount of hydrogen generated per unit time, and hydrogen generation. This is because the time and the like can be easily adjusted within a desired range.
Then, when the hydrogen generation layer and a dot shape or the like, unit area (100 cm ²⁾ per, it is preferable that the area ratio of the hydrogen generating layer to a value within the range of 0.1~95cm ^2.
The reason for this is that when the area ratio of the hydrogen generation layer is 0.1 cm ² , stable production may become difficult, and the hydrogen generation time or the like may become excessively short. ..
On the other hand, if the area ratio of the hydrogen generation layer ^{exceeds 95 cm 2} , the air permeability may be significantly lowered, or the hydrogen generation time or the like may be excessively long.
Thus, per unit area (100 cm ^2), it is more preferably set to a value within the range of area ratio of 1～50Cm ² hydrogen generating layer, still more preferably a value within the range of 10-30%.

Further, it is preferable that the average particle size and each line width of each dot in the hydrogen generating layer are set to values within the range of 1 to 5000 μm, respectively.
The reason for this is that when the average particle size of each dot and the width of each line (or the width of the space between lines) are less than 1 μm, stable production is achieved, air permeability is reduced, and the resin is uniform. This is because it may be difficult to disperse in each of them, and further, the hydrogen generation time and the like may become excessively short.
On the other hand, if the average particle size of each dot and the width of each line (or the width of the space between the lines) exceed 5000 μm, it may be difficult to form them stably or to disperse them uniformly in the resin. This is because the hydrogen generation time may become excessively long.
Therefore, when the hydrogen generating layer is formed into a dot shape / line shape, it is more preferable that the average particle size of each dot and each line width be set to a value within the range of 10 to 1000 μm, and within the range of 100 to 500 μm. It is more preferable to set the value.

(8) Hydrogen Generation Control Layer Further, the surface of the hydrogen generation control layer is protected by providing an inorganic material layer made of silazane, silica material, nitrogen, etc. as the hydrogen generation control layer on the surface of the patterned hydrogen generation layer. In addition to improving the properties, the amount of hydrogen generated per unit time, the hydrogen generation time, and the like can be easily adjusted within a desired range, and can be sustained for a particularly long period of time.
When the hydrogen generation adjusting layer is provided, the thickness is usually preferably set within the range of 1 to 200 μm, although it depends on the type of the hydrogen generation adjusting layer.
The reason for this is that if the thickness of the hydrogen generation adjusting layer is less than 1 μm, it becomes difficult to form a uniform thickness, and the function of adjusting the amount of hydrogen generated and the function of the adhesive are significantly reduced. This is because there are cases.
On the other hand, if the thickness of the hydrogen generation adjusting layer exceeds 200 μm, it may be difficult to handle or form the hydrogen generation adjusting layer with high accuracy.
Therefore, the thickness of the hydrogen generation adjusting layer is more preferably set to a value within the range of 10 to 60 μm, and further preferably set to a value within the range of 20 to 40 μm.

[Second Embodiment]
In the second embodiment, as illustrated in FIGS. 6A to 6D, a patterned hydrogen generating layer 12 derived from a hydrogen generating agent-containing resin containing at least a hydrogen generating agent and a resin is provided. It is a method for producing a cloth 14 with a hydrogen generating function, which comprises the following steps (1) to (3).
(1) Step of preparing a predetermined cloth 10 (2) Step of preparing a hydrogen generating agent-containing resin (3) A hydrogen generating agent-containing resin is partially laminated on the front surface and / or the back surface of the cloth 10. Step to make hydrogen generation layer 12

1. 1. Cloth preparation step As shown in FIG. 6A, the cloth preparation step is a step of preparing a woven fabric having a predetermined shape or a predetermined shape in a sheet shape or a roll shape.
More specifically, for example, the sanitary masks 20 and 20'shown in FIGS. 3 (a) to 3 (b), the socks 30 shown in FIGS. 4 (a) to 4 (b), and FIGS. 5 (a) to 5 (b). Prepare a cosmetic face mask 50 and its auxiliary parts 60 shown in the above, or a cloth having a hydrogen generating function in the form of sheets, bedding of macula, a hydrogen generating sheet, or a shape suitable for those uses, although not shown. It is preferable to do so.
Since the aspect of the fabric with the hydrogen generation function can be the same as that described in the first embodiment, the description thereof will be omitted again.

2. Preparation Step of Hydrogen Generator-Containing Resin Since the aspect of the hydrogen generator-containing resin can be the same as that described in the first embodiment, the description thereof will be omitted again.
As will be described later, since it is easy to partially laminate the hydrogen generating agent-containing resin on the fabric, the amount and type of the diluent, the adjustment of the solid content, the amount and type of the viscosity modifier, and the addition are added. The blending amount and type of the agent, the blending amount and type of the resin, the lamination temperature, etc. should be appropriately changed so that the viscosity of the hydrogen generating agent-containing resin is within the range of 100 to 100,000 mPa · sec (measurement temperature: 25 ° C.). Is preferable, and the value is more preferably in the range of 300 to 10000 mPa · sec.

3. 3. Laminating step of hydrogen generating layer Further, regarding the laminating step of the hydrogen generating layer, that is, the partial laminating step of the hydrogen generating agent-containing resin, a predetermined hydrogen generating agent-containing resin can be laminated by various methods, but it is more preferable. Is the printing method.
The reason for this is that by forming a predetermined hydrogen generating layer by such a printing method, the hydrogen generating agent is contained in the resin regardless of whether the area is large or small with respect to the desired portion. This is because the hydrogen generating layer derived from the hydrogen generating resin composition can be formed with extremely high accuracy in terms of area, thickness, and the like.
Further, according to the printing method, the hydrogen generation layer can be partially and accurately formed, and the amount of hydrogen generated per unit time, the hydrogen generation time, and the like can be easily adjusted within a desired range. Because.

Here, the printing method is preferably at least one of a roll coating method, a gravure coating method, a knife coating method, a screen printing method, an inkjet method, a brush coating method, and the like.
In particular, in the screen printing method, even when a metallic hydrogen generating agent such as magnesium is used, the wear damage of the coating device can be reduced as compared with the gravure coating method or the like.
Further, the screen printing method can be used for producing a large number of lots and a small amount of fabric with a hydrogen generating function.
Furthermore, as a cloth, simply prepare gauze with openings (corresponding 1 to 4) and immerse it in a hydrogen generating agent-containing resin, or roll coat or brush the hydrogen generating agent-containing resin. Therefore, it is also possible to use a fabric with a hydrogen generation function in which the hydrogen generation layer is printed in a pattern.
As a modification of the printing method, in order to make the thickness of the hydrogen generating layer more uniform and to improve the adhesion to the fabric, a dot-shaped / patterned hydrogen generating layer is formed in advance on the peeling base material. A transfer method may be used in which the hydrogen generating layer including the base material is directly transferred to the cloth, or further, the hydrogen generating layer is attached to the cloth using an adhesive, a mechanical joining member, or the like. ..

In addition, when the resin constituting the hydrogen generation layer is a cured product of a photocurable resin (ultraviolet curable resin), as shown in FIG. 6 (c), a screen-printed photocurable resin (ultraviolet curable resin). ) 12'is also preferably irradiated with a predetermined amount of light (ultraviolet rays).
The reason for this is that by using a photocurable resin (ultraviolet curable resin) 12'or the like, as shown in FIG. 6D, the hydrogen generating layer 12 can be formed quickly and firmly.

4. Processing Step Next, it is preferable to provide a processing step of the fabric with a hydrogen generating function and process it into a sanitary mask or the like having a predetermined form.
More specifically, for example, in the case of the sanitary mask 20 shown in FIGS. 3A to 3B, the cloth 14 with a hydrogen generating function can be cut or sewn, and further, the ear strap 18 can be used. It is preferable to provide a processing step in which a sanitary mask or the like is provided in a predetermined form.

Further, in the case of the socks 30 shown in FIGS. 4 (a) to 4 (b), the cloths 30'and 30'with a hydrogen generating function can be adhered to or sewn to a predetermined position of the socks, or the hydrogen generating function can be obtained. It is preferable to prepare a thread with a hydrogen generating function or a cloth with a hydrogen generating function as the attached cloth, and knit or weave it to obtain the sock.
Here, in the case of the sock 30 shown in FIG. 4A, it is an example in which the fabrics 30 ′ and 30 ″ with the hydrogen generation function are partially provided on the toe portion and the heel portion inside the sock 30. In this mode, the cloths 30 ′ and 30 ″ with a hydrogen generating function can be attached intensively and economically to places where water bugs and cracks are likely to occur.
Further, in the case of the sock 30 shown in FIG. 4B, the cloth 30 ″ with a hydrogen generation function is provided on the entire bottom of the inside of the sock 30, and the cloth 30 ″ with a hydrogen generation function is provided. This is an aspect that facilitates the simplification of the laminating process of ′.

Furthermore, in the case of the cosmetic face mask 50 and its auxiliary parts 60 shown in FIGS. 5A to 5B, the cloth with a hydrogen generating function is simply cut into a predetermined shape, and the cosmetic mask or the like can be used. Can be. Therefore, as a cosmetic mask or the like, a predetermined hydrogen is generated only by impregnating with a cosmetic water, and a beauty effect and an anti-aging effect can be exhibited.
In addition, for sheets and pillow bedding, cut the cloth with hydrogen generation function, sew a hem to prevent the edges from fraying, attach fringes around it, and even use a hydrogen generation sheet. If so, it is preferable to form a protective layer or a decorative layer so that the alkaline component from the hydrogen generating agent does not elute to the outside, or to provide a surface processing step such as a smoothing treatment / roughening treatment. ..
