Description

wig for headgear

technical field

The present invention mainly relates to a kind of headdress wigs such as wigs and small wigs whose color changes due to the irradiation of light such as ultraviolet rays (that is, photosensitive reversible discoloration).

Background technique

In recent years, especially among young men and women, it is popular to change the hair color into brown, yellow, red, etc. This is to decolorize black hair and dye it to another favorite color. As the hair grows, the black hair that grows from the scalp and the dyed part are different in color and stand out. Therefore, it is necessary to decolorize and dye again, which not only costs money and time, but also damages the hair itself. Although there are special dyes for hair dyeing, the same problem also exists because it is used for growing hair.

In addition, there are wigs and wigs as unnatural imitation hair, some of which are dyed from the beginning and then colored again, but they are usually of a single color, and almost never become other colors.

As mentioned above, regardless of whether it is natural hair or imitation hair, troublesome treatments such as decolorization and dyeing are required for discoloration, and discoloration cannot be simply discolored. Therefore, hair that can change color instantly has not been known until now.

In view of the above circumstances, an object of the present invention is to provide a wig for headwear such as a wig, a mini-wig, etc., which can easily change color according to the presence or absence of ultraviolet rays, without requiring special treatment at a specialty store such as a beauty parlor.

Detailed ways

In order to demonstrate this invention in detail, it demonstrates referring drawings.

In Fig. 1, reference numeral 1 denotes a wig for headgear. This wig 1 is a wig in which hair 2 is planted on a net-like base material 3 and equipped with a fixing clip 4. The hair 2 is made of synthetic resin (fiber) or recycled resin. (fiber) made of imitation hair. The wig 1 for a headgear can be set according to the size of the wearing hair.

The wig 1 is not limited to those covering all hair. As shown in Figures 2A and 2B, a partially worn wig is also possible. Although these partial wigs 1 are not shown in the figure, the hair 2 is also implanted on the base material 3 .

In addition, as a high fashion wig, as shown in Figure 3A, the front portion of the pin 5 (fixed clip and base material) is decorated with radial imitation hair 2, along the long wooden comb 6 (fixed clip) in Figure 3B and base material) is equipped with imitation hair 2 for decoration, or as shown in Fig. 3C, the decorative part 3 of hair pin 4 is equipped with imitation hair 2 for decoration. Such wigs include various wigs 1 such as three-braid type, long hairstyle, bun type, spiral type, twist type, zigzag type, etc. in addition to the above-mentioned illustrated examples.

As mentioned above, as long as the imitation hair 2 is installed on the base material 3, it is not limited to hair transplantation. In addition, the base material itself is not limited to be flat, for example, it may also be in the shape of a belt, or as shown in Figure 3A and 3B, it may also have fixing clips. Further, the fixed clip 4 is not particularly limited, and can arbitrarily select hair pins, American pins, comb clips, small hair clips, rubber bands (rings, buttons), buckles, wires, nets, etc.

The imitation hair 2 described below for the above-mentioned wig 1, as described in detail later, is a photosensitive reversible discoloration person that changes color due to light such as ultraviolet rays, that is, changes from one color to another color when illuminated.

The imitation hair 2 may be fully discolored (color change) or partially discolored. When all the colors are changed, the first color may be changed to another color, and the first part of the color may be changed to one color of all. On the other hand, in the case of partial discoloration, as shown in FIG. 4A , a small number of hairs 2 that change in color are mixed with each other and discolored so that all of them can be regarded as a single color. For example, pink hair can be seen mixed with red and white hair. Therefore, in addition to changing red and white to other colors, the white part remains unchanged, and it is also possible to change only the other part to red. In addition, it is also possible that the hairs 2 of different colors are concentrated to a certain extent as shown in FIG. 4B and become discolored. In this case, it is a single color at first, but only a part of it is changed by light irradiation such as ultraviolet rays, or it may be changed to another color from a different color at first. Furthermore, as shown in FIG. 4C, the parts of each hair 2 are different, and may be changed to different colors. In this case, the striped pattern may be formed by irradiation with light such as ultraviolet rays. For example, it may be a single color at first, and the color of a fixed part of each hair 2 may be changed to form a striped pattern when exposed to light, or it may be a striped pattern at first, and another striped pattern may be formed by irradiation with ultraviolet light or the like.

Here, the imitation hair 2 used in the above-mentioned wig 1 includes a fibrous material characterized by containing a photochromic compound. A photochromic compound is a substance that has a function of reversibly changing its color according to light of a specific wavelength such as ultraviolet rays. As the photochromic compound, any of conventionally known compounds can be used without any particular limitation.

Examples include azobenzene compounds, thioindigo compounds, dihydrobromide (jihidropren) compounds, spiropyran compounds, naphthopyran compounds, benzopyran compounds, spirooxine Azine compounds, silver compounds, etc.

On the other hand, various synthetic fibers and regenerated fibers can be mentioned as fibrous substances.

The imitation hair 2 of the present invention contains a photochromic compound, so it changes color when exposed to light such as ultraviolet rays, and returns to its original color after stopping the irradiation, that is, it has the function of photosensitive reversible discoloration.

A preferred configuration of photosensitive reversible discoloration imitation hair is polyolefin fiber containing a photochromic compound with a molecular weight of 300 or more. Polyolefin fiber has good processing characteristics, and at the same time, it is necessary for this application, has low toxicity to the human body, and the possibility of incineration after disposal to produce dioxin and other harmful substances is small. Since polyolefin fibers themselves are generally non-polar, blooming occurs when mixed with polar substances such as photochromic compounds. Therefore, the present invention chooses to use organic photochromic compounds with a molecular weight above 300, thereby solving this problem.

Here, the organic photochromic compound is an organic compound among the aforementioned photochromic compounds, and the type is not limited as long as the molecular weight is 300 or more. However, it is particularly preferable to use at least one compound among spiropyran-based compounds, naphthopyran-based compounds, benzofuran-based compounds, or spirooxazine-based compounds that has high color intensity and rich colors when irradiated with light.

Specifically, the following compounds can be mentioned:

(1) 1,3-dihydro-1,3,3-trimethyl-6'-(1-piperidinyl)-spiro[2H-indole-2,3'-[3H]naphtho[2 , 1-b] [1,4] oxazine] (molecular weight 411);

(2) 6'-(2,3-dihydro-1H-indol-1-yl-1,3-dihydro-1,3,-trimethyl-spiro[2H-indole-2,3' -[3H]-naphtho[2,1-b][1,4]oxazine]) (molecular weight 445);

(3) 1,3-dihydro-1,3,3-trimethyl-6'-(1-piperidinyl)-4-(trifluoromethyl)-spiro[2H-indole-2,3 '-[3H]naphtho[2,1-b][1,4]oxazine] (molecular weight 479);

(4) 1,3-dihydro-1,3,3,4,5-pentamethyl-spiro-[2H-indole-2,3'-[3H]naphtho[2,1-b][ 1,4-oxazine] (molecular weight 356);

(5) 3,3-diphenyl-3H-naphtho[2,1-b]pyran (molecular weight 334);

(6) 6-Methoxy-2,2-diphenyl-2H-chromene (molecular weight: 314).

On the other hand, as the polyolefin fiber, any known polyolefin fiber can be used without particular limitation. For example, a wide range of fibers such as polyethylene fibers, polypropylene fibers, and ethylene-propylene copolymer fibers can be used. In addition, these fibers can also be partially cross-linked, and can also be copolymerized with acrylonitrile, (meth)acrylic acid, (meth)acrylate, vinyl acetate, styrene, vinyl chloride, vinylidene chloride, etc. or alone cooperative.

In addition, the above-mentioned polyolefin fibers can be mixed with various pigments to make the above-mentioned organic photochromic compounds, which usually have a color-changing property between colorless and colored, achieve more abundant color changes. Here, in order to improve the dispersion of the pigment in the fiber, it is preferable to use a dispersant. It is most preferable to use a wax-type dispersant that does not inhibit the color-changing properties of the above-mentioned organic photochromic compounds.

Here, the above-mentioned pigments can include organic pigments, inorganic pigments, fluorescent pigments, luminescent pigments, pearlescent pigments, metallic pigments, gold powder, silver powder, glass powder, thermochromic capsule pigments, microcapsules containing fragrances, etc., but are not limited to only is these.

In addition, examples of wax-type dispersants include polyethylene wax, polypropylene wax, paraffin wax, polybenzamide wax, wax, carnauba wax, and microcrystalline wax, but are not limited thereto.

Such photosensitive reversible discoloration polyolefin fibers can be used for the production method of the imitation hair of the present invention, and any method known so far can be used, and there is no particular limitation. For example, the above-mentioned components can be made into colored granules, or they can be directly mixed with the polyolefin forming the fiber aggregate and melt-spun using a melt-spinning device. At this time, by changing the shape of the spinneret, spinning speed or draw ratio, etc., various cross-sectional shapes (such as circular, oval, star, triangle, gear-shaped, etc.) and different thicknesses (such as 0.1 ~50μm) fibers.

In addition, the imitation hair of the present invention may contain conventionally known various additives as necessary in addition to the above-mentioned components.

Examples of such additives include ultraviolet absorbers, light stabilizers, fillers, dyes, fluorescent dyes, electrochromic agents, liquid crystals, ultraviolet light-emitting pigments, fragrances, flame retardants, fireproofing agents, deodorants, antibacterial agents, and preservatives. , antifungal agent, repellent, photocatalyst, etc., but not limited to these.

In addition, the imitation hair of the present invention has a structure other than the above, such as a core/sheath type conjugate yarn containing an organic photochromic compound in the core (JP-A-4-202811).

Next, how to wear the wig of the present invention will be described. For example, when the wig 1 shown in Fig. 3A and 3B is worn, generally a part of the hair 7 is tied to the side or top of the head as shown in Fig. 5A and 5B, or it can be tied into a ponytail. Then imitation hair 2 is fixed with fixing clip 4. When the wig 1 of Fig. 3B is worn on the hair of Fig. 5A, it becomes as shown in Fig. 6A, and when the wig 1 of Fig. 3B is worn on the hair of Fig. 5B, it becomes as shown in Fig. 6B. In any case, it is possible to wear the wig deliberately so that it can be seen, but the base of the wig 1 is preferably worn with hair, a large turban, a small turban, or the like. Of course, the above-mentioned wigs can also be worn in combinations of more than one type of work.

In addition, the wig shown in FIG. 3C will be described in detail. The fixing clip shown in Fig. 3C has a decoration part, a hair pin part and an imitation hair putting on and taking off part. As shown in Fig. 3D, the imitation hair is rolled up between the decorative part and the pin part, and fixed with a simple means such as a rubber band. It can also be fixed as shown in Figure 3E, and of course it can also be fixed with an adhesive.

Also, hairpins like those shown in Figures 3F and 3G have always been commercially available. The imitation hair is installed on the hair pin, which can be designed in the decorative part and the joint means of the hair pin part as shown in Fig. 3F, as long as it is free to wear and remove. Also, when using the hair pin as shown in Fig. 3G, the imitation hair is curled around the hair pin part, and as mentioned above, it is sufficient to fix it with a rubber band or the like.

After the user loads the wig 1 made of the above-mentioned imitation hair 2 on the head, the wig 1 is irradiated with light of a specific wavelength such as ultraviolet rays, and the imitation hair 2 becomes blue, red, yellow, green and other colors. Thereafter, the light irradiation was stopped, and the original color was restored. In this way, the color of the hair 2 changes only by light irradiation such as ultraviolet rays. For example, the color of the hair 2 of the wig 1 changes when it is irradiated with sunlight from inside a building to outside or from outside to inside a building. Due to the change of color, the impression on the user also changes, so the impression can also be changed in the same day.

Also, the color of the ornamental wig 1 can be changed automatically without special maintenance and handling, and it is very easy to use.

In addition, there is no need for the trouble of special treatment at professional shops such as beauty salons, and the color changes simply according to the presence or absence of ultraviolet rays, which is inexpensive and convenient.

Also, the user does not need to directly dye the hair, so it does not damage the hair.

Further as shown in FIG. 7, since the child uses the above-mentioned wig 1, the mother or the toy doll 8 with discolored hair can obtain a sense of unity. That is, if the mother’s hair is green, if she wears a wig that turns green before or after the color change, and the doll also changes from pink to green, then she can also wear a color-changing wig 1 to obtain a sense of unity between the mother or the doll .

Furthermore, a part of the above-mentioned imitation hair 2 may be reversibly discolored according to temperature. That is, it can be composed of photosensitive reversible discoloration imitation hair according to the presence or absence of light irradiation such as ultraviolet rays and temperature-sensitive reversible discoloration imitation hair according to temperature.

At this time, as the temperature-sensitive color-changing material used for imitating hair with temperature-sensitive reversible discoloration, for example, as disclosed in USP3560229, examples include electron-donating color-forming compounds (white pigments) and electron-accepting color-developing agents. Combination of (phenols, etc.) In addition, Japanese Patent Publication No. 62-28990 discloses compositions containing thermochromic materials in so-called microcapsules, and it is also suitable to use these compositions. Therefore, these temperature-sensitive color-changing materials are uniformly mixed with polyolefin resin or polypropylene, polyamide, etc., and extruded into a filament-shaped molded body to obtain temperature-sensitive reversible discoloration imitation hair (Patent No. 2519484 bulletin, special Publication No. 37-180, etc.).

The temperature-sensitive reversible discoloration imitation hair part is preferably heated by daily heating means such as hair dryer to a certain temperature and then the imitation hair can be changed into blue, green, yellow, red and other colors. After the heating is stopped, the discolored state will be maintained, and the temperature will gradually drop below the indicated temperature of the imitation hair, and then the original color will be restored. In addition, if a temperature-sensitive discoloration agent that changes color at the level of body temperature is used, the discoloration state can be maintained when the wig 1 is worn. Of course, pigments can also be added for purposes such as making the temperature-sensitive reversible color-changing imitation hair present rich color changes.

The photosensitive reversible discoloration imitation hair and the temperature reversible discoloration imitation hair can be combined to make some parts of the imitation hair show various color changes according to the presence or absence of ultraviolet light or other parts according to the temperature. You can enjoy complex and varied color changes.

At this time, in addition to simple discoloration at low cost, the user's hair is not directly discolored, so it can obtain effects such as not damaging the hair like photosensitive reversible discoloration imitation hair.

As mentioned above, the headgear wig according to the present invention can be used on the whole head or a part of the head. For example, when the wig wearer goes outdoors and is irradiated with ultraviolet rays, all or part of the hair turns into a bright color, and returns to its original color when it returns indoors. , and further use imitation hair that changes color according to temperature changes, and can be easily fixed with hair pins, etc., so consumers can appreciate complex hair in a short time and at a low price compared with the time and cost of hair dyeing in beauty salons. Changeable color variations.
