Description

Technical Description Wigs for hair ornaments

The present invention relates to wigs for hair ornaments, such as wigs and false hairs, whose color changes (that is, reversible photosensitivity) depending on the presence or absence of light irradiation such as ultraviolet rays.

Background art

In recent years, it has become popular among young men and women to change the color of their hair to brown, yellow, red, etc. This is to decolorize black hair and dye it in another color of your choice.As your hair grows over time, the parts that grow out of the scalp and grow are black, so they are colored differently from discolored parts. Is noticeable. Therefore, it must be decolorized and dyed again. Therefore, it is expensive and troublesome, and the hair itself is damaged. There is a method of dyeing hair with a special dye, but there is a similar problem because living hair is used. In addition, there are wigs and false hairs that are not natural hairs, such as wigs and false hairs.Some of them are dyed and dyed from the beginning, but all of them are monochromatic and other colors Nothing discolored. As described above, discoloration of natural hair and pseudo-hair requires complicated treatment such as bleaching and dyeing, and discoloration cannot be easily performed. Therefore, there is no known hair whose color can be changed instantaneously.

The present invention has been made in view of the above circumstances, and does not require special treatment at a specialty store such as a beauty salon, and easily changes color depending on the presence or absence of ultraviolet irradiation, wigs, hair, etc. Providing wigs for hair ornaments Is the subject. Disclosure of the invention

In order to solve the above problems, a discolorable hair ornament wig according to the present invention has the following requirements.

(B) The wig is constituted by having at least a part of a photoreversible discolorable pseudo-hair containing a photochromic compound.

(Mouth) Must be large enough to be worn on human hair.

(C) A fastener is attached to a part.

The pseudo hair may be a combination of a photosensitive reversible discolorable pseudo hair and a temperature-sensitive reversible discolorable pseudo hair.

In addition, the pseudo hair may be discolored (color change) as a whole or partially discolored (color change).

And it is preferable that the said stopper has a decoration part, a hairpin part, and a pseudo hair attachment part.

Further, the decorative portion may have a detachable engagement portion with a hairpin, and the stopper and the pseudo hair may be detachable.

The present invention will be described in more detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a hair ornament wig. This wig 1 is a net-like base material 3 on which hair 2 is planted with a stopper 4 attached thereto. The above-mentioned hair 2 is artificial hair made of synthetic resin (fiber) or recycled resin (fiber). is there. Wig 1 is sized to fit on your hair. Wig 1 is not limited to covering the entire hair. The wig may be partially attached as shown in Figs. 2 (a) and (b). Although not shown, these partial wigs 1 are also obtained by implanting artificial hair 2 on a base material 3.

Furthermore, as shown in Fig. 3 (a), a wig with high fashionability is obtained by radially attaching artificial hair 2 for decoration to the tip of pin 5 (stopper and base material). As shown in Fig. (B), the hair is attached with artificial hair 2 for decoration along with long rubber 6 (stopper and base material), or as shown in Fig. (C). For example, there is an artificial hair 2 for decoration attached to the decorative part 3 of 4. This type of wig includes the above example, braid type, long hair type, chignon type, screen type There are various wigs 1 such as torsion type and zigzag type.

In this way, the artificial hair 2 may be attached to the base material 3 in any manner, and is not limited to hair transplantation. The base material itself is not limited to a planar material. For example, it may be a belt-like material, or may also serve as a stopper, as in the base material in FIGS. 3 (a) and (b). Further, the stopper 4 is not particularly limited, and can be freely selected from a hairpin, an amepin, a comb, a knurl, a rubber (ring, string), a string, a wire, a net, and the like.

Next, the simulated hair 2 used in the wig 1 is a photosensitive reversible discoloring material that changes its color by irradiation with light such as ultraviolet rays, as described later in detail. It changes color.

The simulated hair 2 may be one that undergoes a uniform color change (color change) as a whole, or may be one that partially discolors (color change). When the entire color changes, the color initially presented as a whole may be changed to another color, and the color initially partially presented in a different color may be changed to one color as a whole. It may be changed to a color. On the other hand, when the color changes partially, as shown in Fig. 4 (a), the hairs 2 whose colors change are mixed with each other by a small number of hairs. You may do so. For example, red hair and white hair can be mixed to make them look pink. Then, in addition to changing the color of red and white from the other colors, the color of the white portion may not change and only the color of the other portion may change to red. Further, as shown in FIG. 3B, the hairs 2 of different colors may be changed to a certain extent and discolored. In this case, the color is initially a single color, but even if only part of the color changes due to irradiation with light such as ultraviolet light, or if the color is different at the beginning, the color changes to a different unit In things There may be. Further, each hair 2 may be changed to a different color depending on the site as shown in FIG. In this case, a stripe pattern can be formed by irradiation with light such as ultraviolet rays. For example, it may be a single color at first, and when illuminated, the color of the part determined by each hair 2 may be changed so as to become a stripe pattern as a whole, or it may be a stripe pattern from the beginning, and light such as ultraviolet rays Different stripes of different colors may be formed by irradiation.

Here, as the simulated hair 2 used in the wig 1, there can be mentioned a fibrous material characterized by containing a photomouth mix compound. The photochromic compound refers to a substance having a function of reversibly changing color by light of a specific wavelength such as ultraviolet light. As such a photochromic compound, any conventionally known compound can be used, and it is not particularly limited.

Examples thereof include azobenzene-based compounds, thioindigo-based compounds, dihydroprene-based compounds, spiropyran-based compounds, naphthopyran-based compounds, benzopyran-based compounds, spiroxazine-based compounds, and silver-based compounds.

On the other hand, examples of the fibrous substance include various synthetic fibers and regenerated fibers.

By containing such a photochromic compound, the pseudo-hair 2 of the present invention has a photoreversible discoloration property in which the color changes when irradiated with light such as ultraviolet rays and returns to the original color when the irradiation is stopped. It has the function of A more preferred configuration of such a photoreversible discolorable pseudo-hair is a polyolefin fiber containing an organic photochromic compound having a molecular weight of 300 or more. Polyolefin fibers have good processing characteristics, have low toxicity to the human body, which is essential for this type of application, and emit harmful substances such as dioxin when incinerated after disposal. It has various advantages that it is unlikely to do so. However, since the polyrefin fiber itself usually has no polarity, the blooming phenomenon occurs when a polar material such as a photochromic compound is contained. Therefore, in the present invention, this problem has been solved by selectively using an organic photochromic compound having a molecular weight of 300 or more.

Here, the organic photochromic compound refers to an organic compound among the photochromic compounds described above, but does not matter the kind of the compound as long as the molecular weight is 300 or more. However, it is particularly preferable to use at least one compound selected from among spiropyran-based compounds, naphthopyran-based compounds, benzopyran-based compounds, and spiroxazine-based compounds that have a high coloring density upon light irradiation and are rich in color types.

Specifically, for example, the following can be mentioned.

(1) 1,3-Dihydro 1,3,3-trimethyl-6,-(1-pyridinyl) spiro [2H-indole-2,3 '-[3H] naphtho [

2, 1-b] [1, 4] oxazine] (molecular weight 4 11)

(2) 6 '-(2,3-dihydro-1H-indole-1-yl) 1-1,3-dihydro-1,3,3-trimethylspiro [2H-indole-1 2 , 3 '— [3 H] naphtho [2,1-b] [1,4] oxazine] (molecular weight 445)

(3) 1,3-dihydro-1,3,3-trimethyl-1 6 '-(1-pyridinyl) -14- (trifluoromethyl) -spiro [2H-indole-1,2,3 '— [3 H] naphtho [2.1-b] [1,4] oxazine] (molecular weight 479)

(4) 1,3-Dihydro 1,3,3,4,5-pentamethyl-1-spiro [2H-indole-2,3 '-[3H] naphtho [2,1-b] [1 , 4] oxazine] (molecular weight 3 56)

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

(6) 6-Methoxy-1,2,2-diphenyl-1-H-benzopyran (Mw 314)

On the other hand, as the polyolefin fiber, any conventionally known polyolefin fiber can be used, and it is not particularly limited. For example, a wide range of fibers such as polyethylene fiber, polypropylene fiber, and ethylene-propylene copolymer fiber can be employed. These fibers may be partially crosslinked, and may be copolymerized or homopolymerized with acrylonitrile, (meth) acrylic acid, (meth) acrylate, vinyl acetate, styrene, butyl chloride, vinylidene chloride, and the like. It may be mixed.

Further, since the above-mentioned organic photochromic compound usually shows discoloration characteristics between colorless and colored in many cases, such polyolefin fibers are used for various purposes such as further enriching the color variation. Pigments can also be incorporated. In this case, it is preferable to use a dispersant in order to improve the dispersibility of the pigment in the fiber. In particular, it is preferable to use a box type dispersant which does not inhibit the discoloration characteristics of the organic photochromic compound.

Examples of the above pigments include organic pigments, inorganic pigments, fluorescent pigments, phosphorescent pigments, pearl pigments, metallic pigments, gold powders, silver powders, glass powders, samochromic capsule pigments, and perfume-containing microcapsules. The power that can be mentioned is not limited to these.

Examples of wax-based dispersants include polyethylene wax, polypropylene wax, paraffin wax, amide wax, and wax. , Carnauba wax, microcrystalline wax and the like, but are not limited thereto.

As a method for producing the pseudo-hair of the present invention composed of such a photosensitive reversible color-changing polyolefin fiber, any conventionally known method may be used without any limitation. For example, it can be obtained by previously forming each of the above components into a color pellet, or directly mixing with a polyolefin resin as a fiber-forming polymer and melt-spinning using a melt-spinning apparatus. At this time, by changing the shape of the spinneret, the spinning speed or the draw ratio, etc., various cross-sectional shapes (for example, circular, elliptical, star, triangular, gear type, etc.) and thickness (for example, 0. 1 to 500 m).

The artificial hair of the present invention may contain conventionally known various additives in addition to the components described above, if desired.

Examples of such additives include UV absorbers, light stabilizers, extenders, dyes, fluorescent dyes, electoric chromic agents, liquid crystals, UV light emitting pigments, fragrances, flame retardants, and flame retardants. Agents, deodorants, antibacterial agents, preservatives, fungicides, repellents, photocatalysts, etc., but are not limited thereto.

In addition, examples of the configuration other than the above of the artificial hair of the present invention include, for example, a core Z sheath type conjugated yarn containing an organic photochromic compound in the core (Japanese Unexamined Patent Publication No. 4-220281). Gazette). Next, a method for mounting the wig of the present invention will be described. For example, when wearing the wig 1 shown in FIGS. 3 (a) and (b) above, generally, as shown in FIGS. 5 (a) and (b), a part 7 of the hair is Alternatively, it is better to bundle them in a dumpling at a high position on the head as shown in Fig. (B), or to make them like a bonnie tail. Then, the dummy hair 2 is attached to the hair with the fastener 4. To wear. When the wig 1 of FIG. 3 (b) is attached to the hair of FIG. 5 (a), it becomes as shown in FIG. 6 (a), and the wig 1 of FIG. 3 (b) is replaced with the wig 1 of FIG. Fig. 6 (b) when worn on the hair of (b). In either case, the wig may be worn so that it can be recognized as a wig, but it is preferable that the base of the wig 1 be hidden with hair, a bandana, a turban, or the like. Of course, two or more of the above wigs can be attached in combination. Furthermore, the wig shown in Fig. 3 (3) will be described in detail. As shown in Fig. 3 (c), the fastener has a decorative part, a hairpin part and a pseudo hair attachment part. The simulated hair is mounted so as to be wound between the decorative portion and the hairpin portion as shown in FIG. 3 (d), and is fixed by simple locking means such as rubber bands. Further, as shown in FIG. 3 (e), the fixing may be performed by a locking means, or, of course, by an adhesive or the like.

Hairpins as shown in Fig. 3 (f) and (g) have been commercially available. In order to attach the artificial hair to these, as shown in FIG. 3 (f), the decorative portion may be provided with means for engaging with the hairpin portion, and may be detachable. Also, when using a hairpin as shown in FIG. 3 (g), it is sufficient to wrap the pseudo hair around the hairpin portion and lock it with a rubber band or the like as described above.

After wearing the wig 1 made of the simulated hair 2 having the above structure on the wearer's head, when the wig 1 is irradiated with light of a specific wavelength such as ultraviolet light, the simulated hair 2 becomes blue or red. Changes to various colors such as yellow, green, etc. The color returns to its original color when the light is removed. In this way, the color of the hair 2 changes only depending on whether it is irradiated with ultraviolet light or the like.For example, when the hair goes out from the inside of the building and hits the sun, and when it enters the building from the outside. Then, the color of hair 2 of Twitter 1 changes. This change in color also changes the impression received by the wearer, making it possible to make a makeover on the same day. Also, the color of the decorative wig 1 automatically changes without any special care or treatment, making it extremely easy to handle.

Moreover, there is no hassle of special treatment at a specialty store such as a beauty salon, and the color can be easily changed according to the presence or absence of ultraviolet irradiation, so that the cost is low and the convenience is excellent.

Also, since the hair of the wearer is not directly dyed, it does not damage the hair.

Furthermore, as shown in FIG. 7, the child can use the wig 1 to obtain a sense of unity with the mother or the doll 8 whose hair is discolored. That is, if the mother's hair is green, wear the wig 1 whose color before or after the color changes to green, and if the doll changes color from pink to green, wear the wig 1 that changes color similarly. This gives you a sense of unity with your mother or doll.

On the other hand, the simulated hair 2 can be a part of the simulated hair 2 that reversibly changes from one color to another color due to a temperature change. That is, it may be constituted by combining photosensitive reversible discolorable pseudo-hair, which changes its color depending on the presence or absence of irradiation with light such as ultraviolet rays, and thermosensitive reversible discolorable, pseudo-hair, which changes its color due to temperature change.

In this case, examples of the thermosensitive color-changing material used for the thermosensitive reversible color-changing pseudo hair include an electron-donating color-forming compound (US Pat. No. 3,560,229). Examples thereof include a composition based on a combination of a leuco dye) and an electron-accepting developer (such as funinols), and a three-component composition obtained by adding an organic solvent to these two components. Japanese Patent Publication No. Sho 62-28990 discloses a thermochromic material in which these compositions are encapsulated in so-called microcapsules. Such materials are also preferably used. be able to. Then, these thermochromic materials are converted to polyolefin resin. Alternatively, if the mixture is uniformly mixed with polypropylene, polyamide, or the like, and extruded into a filament-like molded product, the pseudo-hair can be manufactured by thermosensitive reversible discoloration (Japanese Patent No. 2519484). Gazette, Japanese Patent Publication No. 37-18◦, etc.).

The temperature-sensitive reversible discolorable pseudo-hair portion turns blue, green, yellow, red, etc. when heated to a predetermined temperature by heating the dummy hair with a commonly used heating means such as a hair dryer. Are preferred. After the heating is stopped, the discolored state is maintained for a while, and when the temperature of the simulated hair falls below the indicated temperature, the hair returns to the original color again. In addition, if a thermochromic agent that changes color at about body temperature is used, the discolored state can be maintained while the wig 1 is worn. Of course, the pigments described above can be added to such thermosensitive reversible discoloration pseudo hair for the purpose of enriching the color variation.

By combining the photoreversible color-changing pseudo-hair and the thermo-sensitive reversible color-changing pseudo-hair, one part of the pseudo-hair changes its color depending on the presence or absence of light irradiation such as ultraviolet rays, and the other part changes its color depending on the temperature change. You can enjoy complex color changes.

In this case as well, it can be easily discolored at low cost, and since it does not directly discolor the wearer's hair, it does not hurt the hair. The effect of is obtained. Industrial applicability

As described above, the hair ornament wig according to the present invention can be used for the whole or part of the head, and when the wig wearer goes out, for example, and is irradiated with ultraviolet rays, the entire hair Or, it has the effect of partly discoloring gently, returning to the interior as well as returning to the interior.Furthermore, discoloration due to temperature changes. As a result, consumers can enjoy more complex color changes in a much shorter time and at a lower cost compared to the time and cost of dyeing hair at a hair salon.
