Description

  The present invention relates to a wig, and more specifically, the effect of suppressing the temperature rise between the head of the wig wearer and the wig base is maintained by coating the wig base with a heat conductive compound having thermal conductivity. It relates to a wig that can be obtained.

  Conventionally, wigs are produced by implanting hair such as natural hair or artificial hair on a wig base using, for example, a thin sheet member or a net member. Recently, since comfort at the time of wearing is demanded, it is often made of a net member having excellent moisture permeability. However, even with a wig made of a highly breathable net member, when hair is implanted on the wig base, the heat generated from the scalp cannot be efficiently dissipated when wearing the wig, Stickiness occurred, and it was impossible to wear the wig comfortably. In addition, since heat tends to be trapped between the head and the wig base, it becomes easier for bacteria to propagate, and in order to keep the scalp clean, it is necessary to remove the wig from the head and wash it frequently. Become. Furthermore, if the wig is not washed frequently, the scalp cannot be kept clean, which may contribute to skin diseases. Therefore, for example, it is conceivable to create a wig base using a fiber using a heat conduction function as disclosed in Patent Document 1. Patent Documents 2 and 3 propose wigs using metal oxides or sugar alcohols.

JP-A-6-313267 Japanese Patent No. 2977723 JP 2005-290599 A

  However, the fiber using the heat conduction function of Patent Document 1 is a fiber in which a heat conductive compound is fixed to the fiber with a single layer coating by means of dipping or coating, but this fiber is used as a wig. Therefore, when processed as a wig, the air permeability and heat dissipation may be deteriorated due to the large number of hairs planted in the wig. In addition, there is a concern that sweat and sebum from the scalp accumulate and become dirty, which accelerates the deterioration of the fiber, and the thermal conductive compound is easily peeled off and the durability is inferior. Furthermore, there has been a problem that the effect of suppressing the temperature rise cannot be obtained continuously for a long time only with the layer of the heat conductive compound.

  Moreover, the wig to which the metal oxide of Patent Document 2 is added may cause metal allergy when a substance such as copper oxide or zinc oxide is slightly dissolved by sweat and comes into contact with the skin.

  Furthermore, the wig to which the sugar alcohol of Patent Document 3 is added suppresses the temperature rise by an endothermic reaction that takes heat when the solidified sugar alcohol absorbs moisture and dissolves, so that after the endothermic reaction occurs There is a problem that the effect is not reduced and does not last. When sugar alcohol is included in microcapsules, etc., in order to obtain the effect of suppressing the temperature rise again, the wig is once removed from the head and dried, and the dissolved sugar alcohol in the microcapsule is solidified. Therefore, there is a problem that it takes a lot of time and the effect of suppressing the temperature rise is remarkably reduced when the wig is worn for a long time. Further, when sugar alcohol is attached to the wig base, the mesh of the net member is easily clogged, so that there is a problem that the moisture permeability is lowered and the effect of suppressing the temperature rise is also lowered.

  The present invention has been made in view of the above problems, and is provided with a wig by forming a heat conductive layer on the surface of the wig base, which is coated with a mixture of a heat conductive compound having heat conductivity and a binder resin. It aims at providing the wig which can obtain the effect which suppresses the temperature rise between a person's head and a wig base continuously.

  It is another object of the present invention to provide a wig that can keep the scalp clean even if the wig is worn for a long period of time, while suppressing the amount of sweat and the propagation of various bacteria.

In order to achieve the above-described object, the present invention provides a wig formed by implanting hair on a wig base formed by a net member, and has a thermal conductivity on the outer peripheral surface of a filament constituting the net member. The heat conductive layer which coat | covered the mixture of an organic compound and binder resin was formed .

In order to achieve the above-described object, in one embodiment, in the wig, the heat conduction layer is thicker on the head contact surface side than on the hair planting surface side of the net member forming the wig base. It is formed so that it may become.

In order to achieve the above object, in one embodiment, in any of the above wigs, the thermally conductive compound includes silylated silicic anhydride, cetyl 2-ethylhexanoate, ethylene oxide, and alcohols. It is characterized by being.

In order to achieve the above object, in one embodiment, in any one of the wigs, an antibacterial agent layer formed by mixing an antibacterial agent and a binder resin is further provided inside the heat conductive layer. It is characterized by.

In order to achieve the above-mentioned object, in one aspect, in the wig, the antibacterial agent includes at least one selected from deacetylated chitin, perillaldehyde, thionel, berberine, or aloetin. .

  According to the wig according to the present invention, the heat conductive layer having the heat conductive compound formed on the surface of the wig base captures the heat generated at the head and dissipates it, so-called heat absorption and heat dissipation, so that the wig wearer There is an effect that the temperature rise between the head and the wig base can be continuously suppressed.

  According to the wig of the present invention, the effect of suppressing the temperature rise between the head of the wig wearer and the wig base by changing the thickness of the heat conductive layer between the wig base surface side and the back surface side. Since the effect becomes more prominent and the effect is further sustained, there is an effect that even if the wig is worn for a long time, the wig can be comfortably worn without heat build up between the head and the wig base. .

  Furthermore, according to the wig according to the present invention, by providing the antibacterial agent layer, there is an effect that the amount of sweating and propagation of various bacteria can be suppressed and the scalp can be kept clean.

It is a top view which shows one Embodiment of the wig which concerns on this invention. It is a cross-sectional view of the wig shown in FIG. It is sectional drawing which shows the heat conductive layer and antibacterial agent layer which were formed in the outer peripheral surface of a filament.

  Hereinafter, a preferred embodiment of a wig according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view showing an embodiment of a wig according to the present invention, and FIG. 2 is a cross-sectional view of the wig shown in FIG.

  The illustrated wig 1 is roughly provided with a main body net member 2 processed according to the head shape of the wig wearer and a fastening means for fastening to the head of the wig wearer. It comprises a wig base 1 a formed by a fastening base net member 3 sewn on the peripheral edge of the main body net member 2. The material of the main body net member 2 and the fastening base net member 3 is not particularly limited, but is preferably formed of polyester having excellent shape stability.

  As shown in FIG. 2, the wig base 1 a has a generally bowl-like shape simulating a head shape, and the concave surface side comes into contact with the head when the wig is mounted (hereinafter referred to as “head contact surface side”). 5 ”), and the convex surface side is a surface on which hair is implanted (hereinafter referred to as“ hair implantation surface side 6 ”). The wig 1 is configured by planting natural hair or artificial hair on the wig base 1a by a known method. The main body net member 2 constitutes the entire wig base 1a, the fixing base net member 3 constitutes the entire peripheral edge of the wig base 1a with a predetermined width, and the hair 7 is implanted in the entire wig base 1a. However, in FIG. 1 and FIG. 2, only some net members and hair 7 are shown for convenience.

  The net member 2 for the main body and the net member 3 for the fixing base are formed by knitting monofilaments in a substantially flat surface or by twisting a plurality of monofilaments into a single filament. However, in the wig base 1a, a heat conductive layer 11 is formed by coating the outer peripheral surface of the filament 8 with a mixture of a heat conductive compound having heat conductivity and a binder resin. And in this embodiment, as shown in FIG. 3, the antibacterial agent layer 10 which mixed the antibacterial agent and the binder resin is further formed inside the heat conductive layer 11. Although only one monofilament 8 is shown in FIG. 3 for convenience, the filament 8 may be a single filament formed by twisting a plurality of monofilaments.

  Here, the principle that heat does not accumulate between the head even if the wig according to the present invention is continuously worn will be described. When the wig 1 formed by the wig base 1a having the above-described configuration is worn, the heat conductive compound of the heat conductive layer 11 formed on the wig base 1a takes away the heat generated in the head of the wearer ( Heat absorption), the heat taken away is transmitted to the outside of the wig base 1a through the antibacterial agent layer formed by the binder resin to which the heat conductive compound is fixed, and further the antibacterial agent and the binder resin to which the antibacterial agent is fixed. (Heat dissipation action). Since such an operation is performed without intermediate interruption while the wig is being applied, no heat is trapped between the wig base 1a and the head.

  In the case of a structure in which the filament 8 constituting the main body net member 2 and the fastening base net member 3 is directly provided with a heat conductive layer 11 covered with a mixture of a heat conductive compound and a binder resin, heat generated at the head The movement (heat absorption and heat release) can be performed smoothly. That is, in order to effectively obtain the heat absorption and heat dissipation functions, it is necessary that the heat conductive layer 11 be formed on the surface of the wig base 1a so as to be in contact with the head or the outside air. However, when the state of being in contact with the head for a long time like the wig 1 continues, there is a concern that sweat or sebum on the scalp accumulates and dirt and germs grow. Therefore, an antibacterial agent layer 10 formed of a mixture of an antibacterial agent and a binder resin is provided on the outer peripheral surface of the filament 8 constituting the net member 2 for the main body and the net member 3 for the fixing base, and the thermal conductivity is provided thereon. A structure in which a heat conductive layer 11 formed by a mixture of a compound and a binder resin is laminated is preferable. If the head remains in contact with the head for a long time like a wig, the captured heat cannot be efficiently dissipated, and heat accumulates in the wig, increasing the temperature of the gap between the wig and the head. However, it is formed by the filament 8 constituting the net member 2 for the main body and the net member 3 for the fastening base as in the wig 1 according to the present invention, the heat conductive compound, and the binder resin. When the antibacterial agent layer 10 formed by the antibacterial agent and the binder resin is interposed between the heat conductive layers 11, the antibacterial agent layer 10 also serves as a medium for transferring heat. Even if the heat is smoothly transferred to the antibacterial agent layer 10 and the head is in contact with the head for a long time without losing the balance between the heat absorbing action and the heat releasing action, it is difficult for the head to become stuffy or sticky. In addition, since the antibacterial agent is naturally blended in the antibacterial agent layer 10, it is possible to obtain an effect that the propagation of miscellaneous bacteria is suppressed and the wig can be kept in a cleaner state.

  Here, as a heat conductive compound, there exists a mixture of silylated silicic acid anhydride, cetyl 2-ethylhexanoate, ethylene oxide, and alcohol, for example. Specifically, it is a state in which cetyl 2-ethylhexanoate, ethylene oxide, and alcohols are adsorbed on a porous silylated silica having a size of about 5 to 10 nm, and included in microcapsules. As in the conventional type, the heat absorption and heat dissipation functions can be continuously obtained without losing the effect after the microcapsule breaks.

  Further, since the heat conductive compound alone is weak in the fixing force to the filament 8 constituting the main body net member 2 and the fixing base net member 3, the resin serving as a binder for fixing the heat conductive compound to the filament 8 is used. Is required. As resin used as a binder, urethane type resin, acrylic resin, melamine type resin, etc. are good, for example. In consideration of washing durability, adhesiveness, and hydrolysis resistance, urethane resin is preferable. The urethane-based resin used in the wig according to the present invention is a carbonate-based urethane resin obtained by polymerizing diisocyanate and polycarbonate diol. In order to further increase the adhesion force, the urethane resin has a carbodiimide-based crosslinking agent. May be added.

  On the other hand, as the antibacterial agent used in the antibacterial agent layer 10, naturally occurring substances that do not adversely affect the scalp, such as allergic reactions, are suitable. It is preferably selected from organic natural antibacterial agents such as In addition, as the substance forming the antibacterial agent layer 10, a substance having flexibility or moisture retention can be used, but the purpose of the present invention is to keep the scalp clean by suppressing the propagation of various bacteria. In order to achieve comfortable wearing of the wig, it is preferable to use an antibacterial substance. In order to fix the antibacterial agent to the filament 8 constituting the net member 2 for the main body and the net member 3 for the fixing base, a resin serving as a binder, for example, polyglycerol polyglycidyl ether, as well as the fixing of the heat conductive compound. Is mixed with lactic acid as a dispersant and fixed to the filament 8.

  The thickness of the antibacterial agent layer 10 formed on the outer peripheral surface of the filament 8 constituting the main body net member 2 and the fixing base net member 3 is preferably in the range of about 0.1 μm to 1.0 μm. When the layer 10 is less than 0.1 μm, since the amount of the antibacterial agent blended in the antibacterial agent layer 10 is reduced, it is difficult to suppress the propagation of germs, and the effect of keeping the wig 1 clean is obtained. There is a risk that it will not be obtained. On the other hand, when the antibacterial agent 10 exceeds 1.0 μm, the texture of the wig base 1a becomes hard, and there is a possibility that the fit feeling at the time of wearing the wig is lowered.

  On the other hand, although the thickness of the heat conductive layer 11 can be changed according to the condition of the wig wearer, it is preferable to form the heat conductive layer 11 differently on the head contact surface side 5 and the hair planting surface side 6. Specifically, the thickness of the head contact surface side 5 is in the range of 2.0 to 6.0 μm, the thickness of the coating layer on the hair implantation surface side 6 is in the range of 1.5 to 4.5 μm, And it is good to make it the ratio of the thickness of the coating layer of the head contact surface side 5 and the hair planting surface side 6 become the range of 1: 0.7-0.8. By making the thickness of the coating layer on the head contact surface side 5 of the heat conducting layer 11 thicker than the thickness of the hair planting surface side 6, more heat generated at the head is captured and captured. This is because heat can be efficiently transferred, so that the balance between the heat absorption effect and the heat dissipation effect is not lost, and it is difficult for the head to become stuffy or sticky.

  When the thickness of the coating layer on the head contact surface side 5 and the hair planting surface side 6 of the heat conductive layer 11 is less than the above thickness range, the heat generated in the head is captured, and There is a possibility that the function of efficiently moving the captured heat may be deteriorated. On the other hand, when the thickness of the coating layer on the head contact surface side 5 and the hair planting surface side 6 of the heat conductive layer 11 exceeds the above thickness range, the texture of the wig base 1a becomes hard, There is a risk that the fit when wearing a wig is lowered.

[Manufacture of wigs]
Next, the manufacturing method of one embodiment of the wig according to the present invention described above will be described.

  First, as a first step, a heat conductive compound and a binder resin are mixed to prepare a heat conductive solution for forming the heat conductive layer 11. The thermally conductive compound is Marble Cool SC50 manufactured by Shoko Chemical Laboratory Co., Ltd., which is a mixture of silylated silicic anhydride, cetyl 2-ethylhexanoate, ethylene oxide, and alcohol, and the binder resin is carbonate. Resamine D-6300 manufactured by Dainichi Seika Kogyo Co., Ltd. is used as the urethane resin, and Resamine D-52 is used as the carbodiimide crosslinking agent. Specifically, after mixing 8.0% by weight of Marble Cool SC50 and 13.3% by weight of Resamine D-6300 with 77.9% by weight of warm water at 40 ° C., Resamine D-52 is added to 0.8%. Add a weight percent to make a thermally conductive solution.

  As a second step, an antibacterial agent layer 10 of an antibacterial agent and a binder resin is formed on the filament 8 constituting the main body net member 2 and the fastening base net member 3 of the wig base 1a. As the main body net member 2 and the fastening base net member 3, a monofilament made of polyester having a thickness of 40 to 60 [mu] m and knitted in a loop shape with an interval of 30 [mu] m to 250 [mu] m is used. First, an antibacterial agent solution is prepared by mixing 99.99% by weight of water with 0.5% by weight of deacetylated chitin, 0.5% by weight of lactic acid, and 0.01% by weight of polyglycerol polyglycidyl ether. . Next, after the filament 8 constituting the net member 2 for the main body and the net member 3 for the fixing base is immersed in the antibacterial agent solution, the excess antibacterial agent solution is squeezed out with a mangle, and the minute antibacterial solution at 150 ° C. for 1 minute 30 Dry for 2 seconds.

  As a third step, a heat conductive compound and a binder are applied by applying a heat conductive solution to the net member 2 for the main body and the net member 3 for the fixing base formed with the antibacterial agent layer 10 of the above-mentioned antibacterial agent and binder resin. The heat conductive layer 11 which coat | covered the mixture with resin is formed. First, two male gypsums made by imitating the head shape of a wig wearer are prepared, and the main body net member 2 and the fastening base net member 3 are attached and fixed to each other. Next, the thermal conductive solution prepared in the first step is uniformly applied from above the gypsum mold to which the main body net member 2 and the fixing base net member 3 are attached, and dried at 100 ° C. for 2 hours. Then, heat treatment is performed at 150 ° C. for 10 minutes to form the heat conductive layer 11 on the main body net member 2 and the fixing base net member 3, and then removed from the gypsum. In order to form the heat conductive layer 11 with a thickness of the coating layer on the head contact surface side 5 larger than the thickness on the hair planting surface side 6, the heat conductive solution applied to the filament 8 is below the filament 8. Take advantage of trapping on the side. And the heat conductive layer 11 of desired thickness can be formed by adjusting the coating amount per time, the frequency | count of coating, etc. suitably.

  As a fourth step, the main body net member 2 and the fastening base net member 3 are integrated to produce the wig base 1a. First, after attaching the main body net member 2 to gypsum, the fixing base net member 3 is overlaid. Next, the unnecessary net is cut off after sewing the entire periphery of the wig base 1a from the outer peripheral edge 1 mm inside and the position 20 mm from the outer peripheral edge.

  As a fifth step, the hair 7 is implanted in the wig base 1a. In order to plant the hair 7, first, the wig base 1a is fitted and fixed to the male head-shaped mold. Next, after inserting the scissors needle from the hair planting side 6 of the main body net member 2 and the fixing base net member 3 to scoop up the filament 8, the hair 7 is hooked and tied to the scissors of the scissors needle. The hair 7 to be planted is natural hair or artificial hair, and is planted by connecting a folded portion obtained by folding the central portion of the hair 7 in half with the net member.

(Evaluation method)
〔Temperature measurement〕
2. Use a temperature measuring sensor manufactured by Anritsu Keiki Co., Ltd. in a test chamber set to 25 ° C. and 65% RH, attach the tip of the sensor to the forehead, and then cover the sensor. A test piece cut and collected at 0 cm × 3.0 cm was attached. Next, the temperature change of each test piece was measured while changing the room temperature in the range of 25 ° C to 27 ° C. The above measurement was repeated 5 times, and the average value was calculated. Moreover, after washing each test piece 50 times, the temperature change was measured similarly.
(Moisture permeability measurement)
The temperature and humidity of the test chamber were set to 25 ° C. and 90% RH, and the test piece was left for 48 hours, and then measured according to the cup method according to JIS K7129.
[Laundry test]
After 3 g of shampoo was dissolved in 2 liters of warm water of 30 ° C., the test piece was immersed, and the surface side and the back side of the test piece were uniformly washed for 30 seconds and then drained. Next, the test piece was rinsed again with 2 liters of warm water of 30 ° C. for 30 seconds, and moisture was removed by sandwiching the test piece with a towel, followed by drying at 60 ° C. for 10 minutes with a dryer.

Based on the wig manufacturing process described above, a wig 1 as shown in FIG. 1 was manufactured under the following conditions.
Wig size:
From the forehead to the back of the head: 18cm
From right to left head direction: 16cm
Area: 288 cm ²
Thickness of head contact surface side: 3.36 μm
Hair planting surface thickness: 2.55 μm

[Comparative Example 1]
The wig of Comparative Example 1 was the same as the example except that no substance adhered to the filament 8.

[Comparative Example 2]
The wig of Comparative Example 2 was the same as the example except that the filament 8 in which the antibacterial agent layer of the antibacterial agent and the binder resin was formed as a single layer was used.

[Comparative Example 3]
The wig of Comparative Example 3 was the same as the Example except that the filament 8 in which only the binder resin layer for the Marble Cool SC50 was formed as a single layer was used.

[Comparative Example 4]
The wig of Comparative Example 4 was the same as the example except that the filament 8 in which only the Marble Cool SC50 was formed as a single layer was used without mixing the binder resin.

〔result〕
As shown in Table 1, the wig of the example was 33.2 ° C. at an initial room temperature of 25.0 ° C., which was slightly higher than that of Comparative Example 1 to which nothing was added. Showed the lowest temperature of 32.8 ° C. for 60 minutes of continuous wear at room temperature, which changed over time. In contrast, the wig of Comparative Example 1 was initially a low temperature of 32.9 ° C., but was 33.8 ° C. after 60 minutes. As a result, the wig of the embodiment suppresses the amount of sweat without causing heat to accumulate between the head and the wig base by continuously suppressing the temperature rise between the head and the wig base of the wig wearer. It was confirmed that the scalp was kept clean and the wig could be worn comfortably. As shown in Table 2, the effect was not changed even when washing was repeated, and the wig could be comfortably worn.

  On the other hand, since the wig of Comparative Example 1 is made using the filament 8 to which no substance is attached, as shown in Table 1, it is more immediately after the pasting than the wig of the Example. The temperature is low and the moisture permeability is excellent as shown in Table 3. However, as shown in Table 1 and Table 2, it becomes impossible to suppress the temperature rise according to the temperature change in the measurement chamber with the passage of time, and heat gradually accumulates between the head and the wig base, The amount of sweat increased, the scalp was kept clean, and the wig could not be worn comfortably.

  Moreover, since the wig of the comparative example 2 produces the wig using the filament 8 in which only the antibacterial agent layer is formed as a single layer, it is possible to suppress the propagation of germs and the like, but the heat conduction layer 11 and the heat generated in the head cannot be captured, so that the temperature rise between the head and the wig base 1a cannot be suppressed, the amount of perspiration increases, and the wig can be worn comfortably. could not.

  In Comparative Example 3, since the wig is produced using the filament 8 in which only the binder resin for forming the heat conductive layer 11 is formed as a single layer, the antibacterial agent, the binder resin, and the heat conduction are prepared. The compound is not attached. Therefore, although heat is released, the heat generated at the head cannot be captured (heat cannot be absorbed), so that the temperature rise between the head and the wig base cannot be suppressed, and the heat accumulates and the amount of sweating increases. In addition, since propagation of germs and the like cannot be suppressed, the scalp was kept clean and the wig could not be worn comfortably.

  In Comparative Example 4, a wig is produced using a filament 8 in which only a heat conductive compound is formed as a single layer. As shown in Tables 1 and 2, the wig is almost the same as Comparative Example 1. As a result, it is considered that the thermal conductive compound alone has a weak adhesion to the filament 8 and the thermal conductive compound is considered to have peeled off from the filament 8, and therefore, according to the temperature change in the measurement chamber over time. The increase in temperature could not be suppressed, heat was trapped between the head and the wig base, the amount of sweat increased, and the wig could not be worn comfortably.

  As described above, the preferred embodiment of the present invention has been described in detail. However, the present invention is not limited to the specific embodiment, and within the scope of the gist of the present invention described in the claims, Needless to say, various modifications and changes are possible.
