Description

  The present invention relates to a hat capable of promoting hair growth that promotes hair growth and prevents hair loss by releasing natural hair-growth ingredients while comfortably warming the wearer's head with far-infrared radiation to improve blood circulation in the scalp.

  So-called balding is alopecia or trichomes, which is a condition in which hair is absent or sparse in the thickness or number of heads that should be normal. . When a person's head is bald, it is very noticeable and the appearance is clearly lacking in youthfulness and beauty, so when head hair removal progresses, even if the actual effect is small, a hair growth agent There are many people who spray hair and hair-growth agents or wear wrinkles and hair pieces. However, there are various causes of hair loss and there is still no clear explanation, so there is no unified treatment at present.

  The major alopecia is alopecia areata, which accounts for about 70% of hair diseases, and this is a circular or oval hair loss patch appearing on the head with hair almost without any subjective symptoms, often progressing and expanding. Expand the area and fuse to form irregular shaped lesions. When this lesion expands, it may extend to the entire head as malignant alopecia, and the hair in the whole body will fall off in severe cases. The cause of epilepsy is unknown, and there are various theories such as focal infection theory, neuropathy theory, heredity, autoimmune disease, capillary stenosis theory, and circulating male hormone theory, but there is no certainty. One of the most promising theories is the stenosis of capillaries, the temperature of the scalp that begins to bald is markedly reduced, and the thinning of the subcutaneous blood vessels in the scalp reduces the blood flow to the hair root, causing baldness and hair loss. It is the theory that At present, it is considered that the capillary stenosis theory has considerable credibility, and many hair restoration therapies, hair restoration instruments or hair restoration agents based on this theory have already been proposed.

Scalp massage is preferred as a hair growth therapy for the capillary stenosis theory, and there is a hair growth brush in consideration of the efficiency of scalp massage in this hair growth device, and a drug having a vasodilating action has been proposed as a hair growth agent . This hair growth device is basically used easily for a long time, and for this purpose, it is desirable to have a normal garment or hat shape for daily wear. For example, a hair growth promotion hat shown in JP-A-9-206389 uses a laminated fabric in which a material containing far infrared rays is printed in an arbitrary pattern on the surface of the first fabric, and the second fabric is press-formed on the printed surface. . Moreover, the fiber product for hair growth of Unexamined-Japanese-Patent No. 2001-276233 is a hat, food | hood, a hair band, etc., and uses the fiber which contains or adhered the negative ion generating substance.
JP-A-9-206389 JP 2001-276233 A

  All of these conventional hair-growth therapies, hair-growth devices, and hair-growth agents are relatively expensive, but there is a problem that the effect of preventing hair growth and preventing hair loss cannot be sufficiently achieved. The cause of this is that even if the scalp blood vessels are expanded by scalp massage such as brushing, the duration of the scalp temperature rise is too short, and even if hair growth agents are used together, the duration of the scalp temperature rise It is estimated that it is only about 20 minutes even if is long.

  On the other hand, the hats disclosed in JP-A-9-206389 and JP-A-2001-276233 simply warm the scalp gently, even if it is sufficient for the duration of the temperature rise of the scalp to be long. Therefore, the thermal effect is small, and it has not yet been possible to sufficiently promote hair growth and hair loss prevention. In fact, the hair root receives blood supply from capillaries, and in order to absorb proteins such as keratin, which is the raw material of hair, from the blood, not only the warming of the scalp but also a certain warming temperature. In addition, there must be a natural substance that can absorb the protein.

  The present invention has been proposed in order to improve the above-mentioned problems relating to conventional hair-growth therapy, hair-growth devices such as a hair-growth promoting hat, and the like. An object of the present invention is to provide a hat capable of promoting hair growth, which constantly applies hair growth ingredients to the scalp. Another object of the present invention is to provide a hat capable of promoting hair growth having a good touch as a hat and having water repellency and a waterproof effect.

  The hair-growth-promoting cap according to the present invention is composed of a laminated sheet of soft resin interposing a reinforcing cloth, and a pattern part containing a natural hair-growth component on the back side of the sheet and a pattern part containing a far-infrared radiation material Are mixed and printed. The laminated sheet is cut into sheet pieces of a predetermined size and number and sewed into a hat shape, so that on the back side of the hat, the design part containing the natural hair-growth component and the design part containing the far-infrared radiation material are inside. Exposed to and close to the wearer's scalp when worn.

  The hair growth-promoting hat of the present invention may be composed of a laminated sheet having at least a three-layer structure having a reinforcing cloth, and contains a pattern part containing a natural hair-growth component on the back side of the sheet and a far-infrared radiation material. It is also possible to print the design part mixed together. By cutting this laminated sheet into sheet pieces of a predetermined size and number and sewing them into a hat shape, on the back side of the hat and the back side of the collar part, a design part containing a natural hair-growth component and a design containing a far-infrared radiation material The part is exposed to the inside and close to the wearer's scalp when worn.

  In the hat of the present invention, the laminated sheet has a three-layer structure of a surface resin layer containing fine metal powder, a reinforcing cloth disposed in the middle, and a lower resin layer laminated with the reinforcing cloth, and the surface resin layer The lower resin layer is preferably made of a urethane foam resin.

  The present invention will be described with reference to the drawings. FIG. 5 illustrates a hat 1 capable of enhancing hair growth according to the present invention. The cap 1 only needs to have a shape that can cover the wearer's head as shown in FIGS. 5 to 8, and includes everything that is put on or wrapped around the head. In the present invention, the hat included in the hat includes not only a normal hat but also a hood, a turban, a cap, a hat, a hood, and the like.

  The hair growth-promoting cap 1 according to the present invention is composed of a resin sheet 2 with a reinforcing cloth 5 interposed as shown in FIG. 1, and the laminated sheet basically has at least a three-layer structure. The laminated sheet 2 has at least a three-layer structure having a thin reinforcing cloth 5 such as polyester or nylon, and is usually preferably a three to six-layer structure. The resin layers 3 and 6 are preferably made of a soft and light material as a whole, and are preferably made of a foamable thermoplastic resin or rubber in terms of touch, and particularly preferably made of a foamed urethane resin.

  As illustrated in FIG. 1, the laminated sheet 2 is usually a surface resin layer 3 on which an appropriate surface pattern 7 is printed on the front side, a reinforcing cloth 5 disposed in the middle, and a lower resin layer laminated with the reinforcing cloth. 6 is a three-layer structure. For example, metal powder such as aluminum or silver is added to the surface resin layer 3 in a resin such as urethane resin, and the tensile strength of the sheet 2 is increased by the reinforcing cloth 5. In the surface resin layer 3, instead of adding metal fine powder, a metal foil or a metal film is sandwiched between two resin layers, one of which is a thin protective layer, or aluminum, silver, etc. The metal may be vapor-deposited.

  The surface pattern 7 may be a character, a symbol, or a plan design combining these. If desired, a heat insulating sheet (not shown) that serves to block heat can be disposed between the laminated sheets 2, and the laminated sheet may be further provided with thickness and cushioning properties. . Although this heat insulation sheet has the same planar shape as the resin layers 3 and 6, you may arrange | position partially as desired.

  On the other hand, the lower resin layer 6 is located below the surface resin layer 3 and is the same material as the surface resin layer 3 such as foamed urethane resin so as to achieve complete waterproofing by heat fusion with the surface resin layer 3. Is preferable. The lower resin layer 6 may be provided with antibacterial properties by a photocatalyst by adding titanium oxide or the like which is a white pigment having a large hiding power. On the surface of the lower resin layer 6, it is possible to apply a thin fabric on the resin layer or partially apply a flocking process after the printing of the back pattern 8 in order to improve the touch.

  On the back side of the lower resin layer 6, a back surface pattern 8 composed of two or more kinds of pattern portions is printed. As shown in FIG. 2 to FIG. 4, the back surface pattern 8 is usually a mixture of a pattern portion 8 a containing a natural hair-growth component and a pattern portion 8 b containing a far-infrared radiation material. The pattern portions 8a and 8b may be simple plane shapes such as a lattice pattern, a mesh pattern, a polka dot pattern, or a circle or a square, and may be any of letters, symbols, complex geometric patterns, concrete patterns, or a combination thereof. However, on the surface of the lower resin layer 6, it is desirable that the total area of the pattern portions 8a and 8b be substantially matched.

  The pattern portion 8a containing a natural hair-growth component is generally formed by adding a natural hair-growth component to a resin binder such as urethane resin or acrylic resin on the surface of the lower resin layer 6, and performing screen printing, roll coating or gravure. It is formed by a printing method. In addition to the appropriate pattern as shown in the figure, the pattern portion 8a may be cut out from the transfer label together with the base sheet and transferred to the lower resin layer 6. When this pattern transfer is performed on the hat 1, the natural hair-growth component is removed. Can be replenished as appropriate.

  Usable natural hair-growth ingredients include hinokitiol, cholesterol, malt extract, D-linemon, cephalanthin (root of Rhizomaceae), dta / tocophenol acetate, dipotassium glycyrrhizinate (legume licorice), panthenol (provitamin) D5) can be exemplified. In addition, sikakai (fruit of legume saponin), jatamashi (underground stalk of Ominaeshi), Brahami (companion of Aceraceae), burin raj (Asteraceae, also known as: Takasaburo), clari sage, hop extract, D-pantothenyl alcohol ( Vitamin derivatives), cucumber extract (leguminous plant Clara root), assembly extract, cordyceps extract (a kind of mushrooms that parasitize insects), button extract (button root, skin), eel extract (root of Scarabaeaceae), tea extract (Raw leaves of Japanese tea), pyridoxine dicaprylate (oil-soluble vitamin B6), Sakuhakuhi extract (root bark of Asteraceae), Arnica extract (flowers and roots of Asteraceae Arnica), Dutch mustard extract (the whole of Alaska) ), Quotanium 51, Chlorella extract, Burdock extract (Asteraceae) Root of the Bow), such as cornflower extract (Asteraceae of cornflower flowers) can be used, it is possible to add one or more of them.

  Preferably, natural hair-growth ingredients such as hinokitiol have low solubility in water, so they are included in cyclodextrins or added as a metal complex with a surfactant, and ethylene glycol, 1,2-propanediol, 1 A polyhydric alcohol such as 3-butanediol is appropriately blended to form an aqueous emulsion. Moreover, you may make this natural hair growth component into the aqueous solution mixed with 1 type, or 2 or more types of amines, As this amines, ammonia, diethylamine, a triethylamine, a dimethylamine, a trimethylamine, a monoethanolamine, N-methyldiethanolamine, Examples thereof include diisopropanolamine and triethanolamine.

  It is preferable that the natural hair-growth component is encapsulated in a microcapsule having a gas sustained-release structure, since the natural hair-growth component is released gradually, so that the effective period becomes longer. The natural hair-growth component is subjected to a vaporization suppression treatment as desired, and is then contained in a permeable microcapsule such as gelatin, urea, melamine, or urethane to give sustained release as the pattern portion 8a.

  For microencapsulation, a small polyethylene ball with innumerable small holes is manufactured, natural hair-growth ingredients are enclosed in the micro-balls, and the natural hair-growth ingredients are released little by little from the small holes of the micro-balls. May be. In such microencapsulation, in order to further improve the protection of the capsule membrane, for example, an excess of about 20% of the reactant used for the membrane insolubilization treatment may be added. Let it go. Formalin, glutaraldehyde, etc., which are the reactants, are removed by complete neutralization.

  The resin binder used in the pattern portion 8a is a coating film forming main element when encapsulated or microencapsulated, and there is no particular limitation on the type together with a coating film forming subelement such as a modifier or additive, Regular items can be used. Examples include aqueous solution type and emulsion type, and resin components include alkyd resin, polyester resin, acrylic resin, epoxy resin, fluorine resin, silicon resin, phenol resin, amino resin, melamine resin, urethane resin, and modified resins thereof. These may be used alone or in combination of two or more. This includes a cross-linked acrylic emulsion and a cross-linked emulsion obtained by using the emulsion in combination with an aqueous polyurethane resin.

On the other hand, the pattern portion 8b containing the far-infrared radiation material is added to the resin binder and printed on the surface of the lower resin layer 6. In the case where the ceramic powder is added in the pattern portion 8b, it is necessary that the ceramic powder radiates far infrared rays having a wavelength of 4 to 20 μm in a high temperature range. As this type of ceramic, for example, alumina (Al ₂ O ₃ ), magnesia (MgO), zirconia (ZrO ₂ ), titania (TiO ₂ ), lanthanum, silicon dioxide (SiO ₂ ), Chromium oxide (Cr ₂ O ₃ ), ferrite (FeO ₂ · Fe ₃ O ₄ ), spinel (MgO · Al ₂ O ₃ ), ceria (CeO ₂ ), beryllia (BeO) and the like can be used. Furthermore, EM ceramic (trade name: EM-X, manufactured by Amron) having antioxidative power can be used.

  In general, the radiation characteristics of ceramics vary greatly depending on the particle size, particle shape, surface state, filling amount, filling resin, distribution structure, etc., even with the same powder material, so advanced material evaluation techniques are indispensable. For example, alumina-silica-based ceramics and oxide-based ceramics have high selective radioactivity even when dispersed in a resin binder, and non-oxide-based ceramic powders have high overall radiation.

  Natural minerals include tourmaline, serpentine (magnesium hydrated silicate mineral), sericite, jade, zeolite, sericite, crystal, oolite, mica stone, etc. It can be illustrated. These are pulverized to form a fine powder and added alone or in combination of two or more with ceramics.

  It is also possible to add inorganic germanium to the pattern portion 8b. For example, it is used in the form of a fine powder of 5 μm or less, and this fine powder is uniformly and sufficiently kneaded with the resin binder. Moreover, there is a possibility of adding a hot spring effect by adding a hot spring functional substance as another functional substance. Such hot spring functional substances are active ingredients contained in hot springs, and are effective in, for example, carbonates such as sodium carbonate, calcium carbonate, and magnesium carbonate, which are effective for chronic stomach catarrh and chronic constipation, chronic eczema and skin diseases. Certain calcium bicarbonate, magnesium bicarbonate, wound, burns, skin disease, sodium bicarbonate effective for chronic stomach catarrh, habitual constipation, sodium sulfate effective for cholelithiasis, calcium sulfate, magnesium sulfate, women Ferric bicarbonate, ferrous sulfate, chronic dermatosis, hyperhidrosis, gynecological disease, chronic dermatosis, rheumatoid arthritis, muscular rheumatism, neuralgia Sulfur, rheumatoid arthritis, muscular rheumatism, neuralgia, chronic gastrointestinal catarrh, radon, radium, etc. To standing.

  These far-infrared emitting materials preferably have an average particle size of about 5 μm or less so that the resin binder constituting the pattern portion 8b has a predetermined mechanical strength and retains abrasion resistance. Further, even when the average particle size is about 10 μm, the average particle size is necessarily pulverized to about 5 μm when it is kneaded and dispersed with a resin by a roll mill (not shown). These radioactive substances are added in a total amount of 15 to 35% by weight in the pattern portion 8b. If the content of the far-infrared radiation material is less than 15% by weight, it is difficult to emit far-infrared radiation quantitatively. On the other hand, if the content exceeds 35% by weight, the amount of filling in the resin will increase too much. It is difficult to maintain the predetermined wear resistance and washing resistance due to a decrease in the mechanical strength.

  Regarding the pattern portion 8b, a far infrared radiation material such as ceramic powder is added to a resin binder such as urethane resin, acrylic resin, polyester resin, or nylon resin. This resin binder solution can be any resin latex, resin emulsion, resin suspension, hydrophilic copolymer, chemically reactive water-soluble resin, etc., as long as it can uniformly knead far-infrared radiation and inorganic germanium fine powder. But you can. For example, it is added to a polyurethane resin or an equivalent soft resin, and the resin is thermally crosslinkable or crosslinkable with time. Since the polyurethane-based resin generally has a low density, far infrared rays having a wavelength of 4 to 20 μm are better than other resins. Polyurethane resins are excellent in elongation, abrasion resistance, impact resilience, and compression fatigue strength, and are less susceptible to delamination and cracking when used in textile products.

  The pattern portion 8b is formed by a screen printing method or a roll coater method. Actually, the blending ratio of the resin binder to the far-infrared emitting material varies depending on the printing machine used, and is determined as an ink having a viscosity suitable for silk screen printing. In silk screen printing, the prepared resin binder kneaded material is used to print on the lower resin layer 6 using a silk screen printer.

  When the thickness of the pattern portion 8b is 8 to 40 μm, a predetermined far infrared radiation effect is obtained. The far-infrared radiation material in the pattern portion 8b generates negative ions due to the presence of moisture due to sweating inside the cap, and not only synergistically enhances the metabolism and cell function activation of cells possessed by the negative ions, but also promotes blood circulation, for example. Also exhibits antibacterial and other effects.

  The hat 1 of the present invention is manufactured by sewing a sewing machine after appropriately cutting the laminated sheet 2. In order to improve the waterproofness and heat insulation of the cap 1, heat fusion with an indenter of a high-frequency welder, impulse welding method or ultrasonic welding method is used completely or partially. Etc. may be used. Preferably, the tape is wrapped with the tape along the sewing line, and the tape may be fused to the lower resin layer 6 so as not to hinder waterproofness.

  The hat capable of enhancing hair growth according to the present invention is made of a soft laminated sheet, so that it feels good and hardly releases the heat in the hat. By radiating far-infrared rays from one design part, comfortably warming the wearer's head by this internal radiation, improving blood circulation of the scalp part, and simultaneously gradually releasing natural hair-growth ingredients from the other design part, Promotes hair growth and prevents hair loss.

  In the hat of the present invention, the design part containing the natural hair-growth component is separated from the design part containing the far-infrared radiation material. As a result, natural hair-growth ingredients and far-infrared radiation materials with different release levels and durations of effect can be set to the optimal release conditions that act on the scalp, making it more effective in promoting hair growth and preventing hair loss for the wearer. Can be improved.

  The hair growth-promoting hat of the present invention is not easily broken by a soft laminated sheet having a reinforcing cloth, and is easy to cover because it has some elasticity. Since the hat of the present invention is made of a laminated sheet having a multilayer structure, it achieves water repellency and waterproofing. When sweating from the wearer's scalp, negative ions are generated due to the presence of this moisture. When the generated negative ions act on the scalp of the wearer, it promotes ionization of sodium and calcium in the blood in the head, weakens the acidified blood, activates the metabolism of blood, Increase the activation effect. In particular, when far infrared rays are emitted together with negative ions, there is an effect of synergistically enhancing these actions, which is beneficial for promoting the health of hair.

  Next, the present invention will be described based on examples, but the present invention is not limited to the examples. As shown in FIG. 1, the laminated sheet 2 used for the hat 1 (FIG. 5) is a foamed urethane-based surface resin layer 3, a polyester thin cloth reinforcing cloth 5 disposed in the middle, and a foam laminated with the reinforcing cloth. It has a three-layer structure with a urethane-based lower resin layer 6. The thickness of the laminated sheet 2 may be about 1 mm.

  A predetermined amount of aluminum fine powder is added to the surface resin layer 3 of the laminated sheet 2 in the urethane resin, and the whole is silver white. On the surface of the surface resin layer 3, an appropriate surface pattern 7 made of characters or figures is printed. This surface pattern may be printed before cutting the laminated sheet 2, or may be printed on the entire cap after sewing the cap, or the design may be transferred by a transfer sheet (not shown) or the like.

  As shown in FIG. 2, the back pattern 8 of the lower resin layer 6 is a mixture of a white design portion 8a containing a natural hair-growth component and a black design portion 8b containing a far-infrared radiation material. It is applied to the surface of the side resin layer 6 by screen printing. For example, the back surface pattern 8 is a polka dot pattern as shown in FIG. 2, and the pattern portions 8a and 8b are uniformly dispersed on a circular plane having the same diameter of 10 mm.

For example, hinokitiol is added to the pattern portion 8a as a natural hair-restoring component. Hinokithiol is one of the compounds contained in the essential oil of hinoki, has antibacterial action and hair growth promoting action, and is also used as a preservative. Hinokitiol is converted into a sodium salt, MCl ₂ (M = Zn, Ni, Cu) is added to the aqueous solution with stirring, washed with water and dried to form a metal complex of hinokitiol.

  Add 20-40% by weight of acrylic resin emulsion to 8-20% by weight of hinokitiol emulsion, styrene maleic acid copolymer emulsion, low molecular weight polyethylene emulsion, glycol ether, tributoxyethyl phosphate, titanium oxide of white pigment Add antifoam. In the obtained resin binder, the precipitation phenomenon that occurs when hinokitiol itself is directly added to the aqueous solution does not occur, and the resin binder becomes stable. Using this resin binder, the pattern portion 8a is intermittently formed on the lower resin layer 6 by a 150 mesh screen plate, and is printed twice with the same screen plate to a thickness of about 20 μm.

  For example, ceramic powder, which is an alumina-silica ceramic having an average particle size of 1.2 μm, is added to the pattern portion 8b as a far infrared radiation material. The 20 wt% alumina-silica ceramic powder is mixed with 70 to 90 wt% of a polyurethane resin solution having a solid content of 20%. To 100 g of this mixed solution, 2 g of silica gel, 5 g of an organic solvent and a black pigment are added and stirred, and further 5 g of isocyanate is added. The pattern portion 8b is dispersedly formed between the pattern portions 8a on the lower resin layer 6 by a 180 mesh screen plate, and is printed twice with the same screen plate to a thickness of about 11 μm.

  The laminated sheet 2 having the back pattern 8 printed on the entire surface is cut into six triangular hat pieces 10 and two crescent-shaped hat pieces 12 as illustrated in FIG. In the collar portion 14, a paper core is inserted and two sheets are put together, the baseball cap 1 is sewn from these hat pieces, and the bottle skin 15 is sewn. In the baseball cap 1, by not providing eyelet holes, when the wearer wears a hat, the thermal effect of the head is enhanced and complete waterproofness is achieved.

  When the baseball cap 1 is put on the wearer's head, on the back side of the hat shown in FIG. 6, hair-growth components are gradually released from the design portion 8a, and far infrared rays are emitted from the design portion 8b. Inside the cap, the temperature rises due to the radiation of far infrared rays, and even if this heat passes through the laminated sheet 2, it is reflected by the surface resin layer 3 to which metal powder is added, and far infrared rays are absorbed throughout the wearer's scalp. It will be applied evenly. Due to the thermal effect of far-infrared radiation and body temperature, the permeability of the released hair-growth component to the hair follicle is enhanced. In addition, negative ions are generated by sweating of the scalp, and when it is put on, the hair-growth components that are close to the wearer's scalp are ionized, and the permeability of each component to the hair follicle increases, thereby improving hair growth and hair-growth effects. Is increased.

  In the laminated sheet 14 shown in FIG. 3, the back pattern 15 on the back side of the sheet has a white pattern portion 16a containing a natural hair-growth component and a red pattern portion 16b containing a far-infrared radiation material mixed in a lattice pattern. Then, it is applied to the surface of the lower resin layer of the sheet by a screen printing method. For example, in the back surface pattern 15, the pattern parts 16 a and 16 b are the same square plane with a side of 10 mm.

  For example, cholesterol is added to the pattern portion 16a as a natural hair restoration component. Cholesterol is a component that has a moisturizing and softening effect, and has a function of hair growth in hair care. Cholesterol is preferably 0.01 to 20% by weight, and more preferably 0.02 to 10% by weight in the resin solution.

  Cholesterol is heated by adding the same amount of hexylene glycol and emulsified in a 5% gelatin aqueous solution having a pH adjusted to 4 to 5 to a particle size of 20 to 30 μm. Next, a 2% gum arabic aqueous solution is added and mixed, and the pH is adjusted again to 4 to 5 while maintaining the water temperature, kept in this state for 60 minutes, and gradually cooled to room temperature. Thereafter, after cooling to 10 ° C. or lower, 25% glutaraldehyde is added for the hardening treatment of the capsule film, and further stirred under cooling to obtain a microcapsule aqueous solution of gelatin film containing cholesterol as a main component. . This aqueous microcapsule solution has a capsule content of 20% and a water content of 80%. To this microcapsule aqueous solution, 30 to 50% by weight of vinyl acetate resin is added, and further, polyvinyl alcohol, white pigment titanium oxide, clay, xylene, dibutyl phthalate, surfactant, and metal salt are added. Using this resin binder, a 200-mesh screen plate is intermittently dispersed and formed on the lower resin layer of the sheet 14, and is printed twice with the same screen plate to a thickness of about 22 μm.

  For example, EM ceramic powder is added to the pattern portion 16b as a far infrared radiation material. 30% by weight of EM ceramic powder is mixed with 70 to 90% by weight of a polyurethane resin solution having a solid content of 20%. To 100 g of this mixed solution, 2 g of silica gel, 5 g of an organic solvent and a black pigment are added and stirred, and further 5 g of isocyanate is added. The pattern portion 16b is dispersedly formed between the pattern portions 16a on the lower resin layer by a 180 mesh screen plate, and is printed twice with the same screen plate to a thickness of about 11 μm.

  As shown in FIG. 7, the laminated sheet 14 is cut into six triangular shapes and two donut shapes, and then the donut-shaped brim portion is put together with two paper cores, around the periphery of the entire periphery. A circular wire 22 is sewn, and a round hat 22 having a collar portion 19 and a donut-shaped collar portion 20 is sewn with a ribbon 18 attached thereto. In the round hat 22, the natural hair-restoring component cholesterol is gradually released to maintain the hair-restoring effect for a long period of time. Further, when the wearer wears a hat, the thermal effect of the head is enhanced, and complete waterproofing is achieved.

  In the laminated sheet 24 shown in FIG. 4, the back pattern 25 on the back side of the sheet is a mixture of a black pattern portion 26 a containing a natural hair-growth component and a black pattern portion 26 b containing a far-infrared radiation material. It is applied to the surface of the lower resin layer by screen printing. For example, in the back surface pattern 25, the pattern portions 26a and 26b are the same multiple concentric circular planes.

  For example, hinokitiol is added to the pattern portion 26a as a natural hair-restoring component. Hinokitiol is mixed with ammonia water and purified water for 30 minutes to obtain a light yellow homogeneous solution.

  An acrylic resin-containing emulsion of 25 to 70% by weight is added to 8 to 20% by weight of a mixed aqueous solution of hinokitiol and ammonia, and further hydroxyethyl cellulose, white pigment titanium oxide, and a surfactant are added. This additive may be a combination of styrene maleic acid copolymer emulsion, low molecular weight polyethylene emulsion, glycol ether, tributoxyethyl phosphate, antifoaming agent, and leveling agent. Using this resin binder which is an acrylic resin emulsion, the pattern portion 8a is intermittently dispersed and formed on the lower resin layer 6 by a 180 mesh screen plate, and is printed twice with the same screen plate. Is about 20 μm.

  For example, tourmaline powder is added to the pattern portion 26b as a far-infrared emitting material. 30% by weight of tourmaline powder is mixed with 70 to 90% by weight of a polyurethane resin solution having a solid content of 20%. To 100 g of this mixed solution, 2 g of silica gel, 5 g of an organic solvent and a black pigment are added and stirred, and further 5 g of isocyanate is added. The pattern portion 26b is dispersedly formed between the pattern portions 26a on the lower resin layer by a 180 mesh screen plate, and is printed twice with the same screen plate to a thickness of about 11 μm.

  As shown in FIG. 8, the laminated sheet is cut into a circular shape, a band shape, and two donut shapes, and then the doughnut-shaped brim portion is put together with two paper cores, and a circular wire is formed around the entire peripheral edge portion. And a hat 34 having a cylindrical portion 30 and a donut-shaped collar portion 32 is sewn with the ribbon 28 attached thereto.
