Description

The present invention relates to a hair extension, and more particularly to a hair extension that employs a novel means for binding hair bundles.

Conventional hair extensions are used to make hair look longer, change hair color, increase volume, etc., and various hair extensions with special knitting methods are provided. Most of these hair extensions employ a method of fixing to their own hair by heat-sealing an extension bundle composed of a plurality of attachment hairs while being wrapped around the user's own hair. Alternatively, there is also a hair extension with a metal tube attached, and such a hair extension adopts a method of adhering to the hair by a seal or an adhesive, although it does not damage the hair. In this way, conventional hair extensions are not a little damaged by heat fusion and adhesion when they are attached, and the removal work becomes complicated, and the hair extensions that have been used once are re-used. There was a problem that it was difficult to use.

In addition, some conventional hair extensions have adopted a method of fixing with a heat-shrinkable tube. However, since the tubular body covered with the heat-shrinkable tube must be heated by an iron when mounting, it takes time and is dangerous to mount, and the removal work is complicated and the hair extension used once is used. There was a problem that it was difficult to reuse.

In order to solve the above problems, there is also a method in which the hair extension bundle is directly tied to the hair and attached without using means such as heat fusion or adhesion, but the thickness of the hair extension bundle is bulky. There is a problem that the hair becomes unnaturally thick bundles, and when the hair is washed, the bundled portion dries poorly, which is unsanitary and may cause a foul odor.

Therefore, in order to solve these problems, as a concrete proposal of the conventional hair extension, for example, it can be attached to the own hair very easily without damaging the own hair, and the binding force of the own hair is high. An "extension" (see Patent Document 1 and Patent Document 2) that is difficult to remove and does not give a sense of discomfort to the user even when lying down has been proposed and has become a known technique. Specifically, it has a main body portion in which hair is bundled and a attachment means for attaching the main body portion to the ground hair, and the attachment means is provided by a string-like body having one end fixed to the main body portion by adhesion. The first loop and the second loop, which are formed and contract by pulling the base end and the tip of the string-like body apart from each other by binding the string-like body, are formed so as to be located at a predetermined distance from each other. It is something that has been done.

However, the proposal of the above "extension" is that by entwining the first loop and the second loop with the own hair, it can be attached without damaging the own hair as compared with the attachment by heat fusion or adhesion. Since the string-like body and the main body are fixed by adhesion, the bonded portion is solidified into a substantially spherical shape with gloss and swells, and the hair is fluttered and the bonded portion is exposed. There was a problem that when it was exposed, it was noticeable and the finish was unnatural.

In addition, as a concrete proposal of conventional hair extensions, it compensates for the disadvantages of hair extensions that are widely used today, eliminates the need for expensive equipment and adhesives, and does not damage the skin and scalp of the practitioner and the practitioner. A "hair extension and hair extension treatment method" (see Patent Document 3) that does not cause skin troubles or burns due to adhesives has been proposed and has become a known technique. Specifically, a thread is provided at the false hair portion and one end of the false hair portion to be tied to the hair for treatment, and the hair is inserted between both ends of the thread and then contracted to cause the hair. A ring portion that can be fixed to the hair is formed.

However, the above-mentioned proposal of "hair extension and hair extension treatment method" is that after binding the thread to the hair, it is necessary to finally cut and dispose of the surplus thread, which is complicated to attach. There was a problem. In addition, since the thread and the false hair portion are connected by adhesion, the bonded portion has gloss and solidifies and swells, and the own hair flutters and the bonded portion is exposed and dewed. There was a problem that it was conspicuous when it was trapped and the finish was unnatural in appearance.

Furthermore, as a specific proposal for conventional hair extensions, "hair extensions" (hair extensions) that can be easily attached to own hair without reducing the actual length of the extension bundle and can shorten the attachment time ( Patent Document 4) has been proposed and has become a known technique. Specifically, it is formed by two or more extension bundles in which a plurality of attachment hairs are bundled and one end thereof is fixed with an adhesive, and a string member in which one ends of the extension bundles are connected to each other. be.

However, in the above "hair extension" proposal, since the extension bundle and the string member are fixed by adhesion, the bonded portion has gloss, solidifies and swells, and the hair flutters. There is a problem that when the bonded portion is exposed and exposed, it becomes conspicuous and the finish becomes unnatural in appearance.

The applicant has problems such as the danger of the mounting means in the hair extension proposed above and the complicated mounting work, and when the mounting location is exposed after mounting, the portion is conspicuous. Focusing on the problem that it can be an unnatural finish, it can be easily and safely attached to your own hair, and even if the attachment part is exposed, it will be indistinguishable from your own hair and will not look strange. We have developed a hair extension that can realize the feeling, and have come up with the proposal of the "hair extension" in the present invention.

The present invention is a hair extension 10 in which a hair bundle 23 is bound to both end portions 21 of a yarn body 20 having a required length and thickness that is knitted and formed by bundling a plurality of fibers, and the hair bundle 23. Consists of a set of hair bodies 23a having a predetermined length tied to the yarn body 20 in a predetermined knotting method, and the plurality of hair bodies 23a gradually shift the knot position in the yarn body 20 to form the yarn body 20. The biggest feature is that the means of being tied to the end 21 is adopted.
Hereinafter, embodiments of the hair extension 10 according to the present invention will be described with reference to the drawings.

The hair extension 10 according to the present invention is not limited to the examples described below, and is within the scope of the technical idea of the present invention, that is, the range of shapes, dimensions, materials, etc. capable of exhibiting the same effects. It can be changed as appropriate within.

1 and 2 are explanatory views showing an embodiment of the hair extension according to the present invention, FIG. 1 is an overall view, and FIG. 2 is an enlarged view of a main part.
The extension according to the present invention is formed by binding hair bundles 23 to both end portions 21 of a yarn body 20 which is formed by bundling a plurality of fibers and knitting them.

The yarn body 20 is an aggregate of fibers, that is, one in which a plurality of fibers are bundled and knitted (twisted), and is composed of twisted yarns formed by industrially twisting. The number of fibers constituting the yarn body 20 is not particularly limited as long as it is a plurality of fibers, but it is formed by bundling and knitting approximately several to several tens of fibers according to a conventional method. The number of such fibers is preferably determined in consideration of the resistance to the amount of hair bundles 23 to be bound.
The fiber in the present invention is a concept including fine yarn. That is, a fine yarn can be formed as an aggregate of fibers, and the yarn body 20 according to the present invention can be formed as an aggregate of the fine yarns.

The length and thickness of the yarn body 20 are not particularly limited as long as they have the required length and thickness, and an embodiment in which the length is, for example, about 30 mm can be considered. The thickness is determined by the thickness and the number of fibers constituting the yarn body 20, and it is conceivable that the thickness when molded into the yarn body 20 is, for example, about 0.6 to 1 mm.

The material of the yarn body 20, that is, the material of the fiber may be a natural fiber (cotton type), a chemical fiber (polyester type), or a mixed fiber thereof, and is not particularly limited. The material is a fiber cotton yarn containing cotton as a main component, or a blended and blended fiber so that the mixing ratio of cotton is 70% or more, thereby exhibiting a high frictional force on the hair of the yarn body 20. In addition to making it difficult for the restrained self-hair to come off, it becomes easy to dye various colors according to the self-hair.

It should be noted that the material of the thread body 20 may be formed of a stretchable material, for example, a stretchable fiber material such as a stretchable synthetic resin fiber or a synthetic rubber fiber. By adopting such an embodiment, the work of attaching to the head and the work of removing and attaching / detaching can be facilitated, the feeling of tightness at the time of attaching to the own hair can be alleviated, and the binding force to the own hair after attachment can be relaxed. It is also possible to effectively prevent damage to the own hair without biasing the binding force.

The color of the thread body 20 is not particularly limited, but is dyed in the same color as or similar to that of the hair bundle 23 (hair body 23a) so that the attachment location is not conspicuous after being attached to the own hair. Is preferable. Dyeing is performed by using a coloring dye composed of various variations according to a conventional method, and the thread body 20 and the hair bundle 23 (hair body 23a) are the same color or an approximate color according to the user's preference. Can be dyed in. In this way, when the thread body 20 and the hair bundle 23 (hair body 23a) are dyed with the same color or an approximate color, the hair extension generated by the different colors of the thread body 20 and the hair bundle 23 (hair body 23a). It is possible to reduce the discomfort of the appearance of the hair itself, and to make the wearing part inconspicuous by blending the color with the own hair without discomfort, and it is possible to achieve a natural finish.

It should be noted that both ends of the thread body 20 employ a means of providing a knot so that the woven fibers are not unraveled, or, if formed of chemical fibers, partially crimping or heat welding to fix them. It is also preferable.

The hair bundle 23 is bound to both ends of the thread body 20, and is an aggregate composed of a plurality of hair bodies 23a. As a material of the hair body 23a, as a general rule, artificial hair formed of chemical fibers (synthetic resin fibers) is used, and in some cases, human hair can be used as it is. When human hair is used, it is preferable to treat it with a surfactant, wash it, and use it in a state where about 50% or more of the cuticle component remains.

The color of the hair bundle 23 (hair body 23a) is not particularly limited, and is dyed in various colors according to the user's preference, such as matching the color of the own hair or producing a special color. .. At this time, it is preferable that the color of the hair bundle 23 (hair body 23a) is dyed in the same color as or similar to that of the thread body 20 so that the attachment portion is not conspicuous after being attached to the own hair. Dyeing is performed by using a coloring dye composed of various variations according to a conventional method, and the thread body 20 and the hair bundle 23 (hair body 23a) are the same color or an approximate color according to the user's preference. Can be dyed in. In this way, when the thread body 20 and the hair bundle 23 (hair body 23a) are dyed with the same color or an approximate color, the hair extension generated by the different colors of the thread body 20 and the hair bundle 23 (hair body 23a). It is possible to reduce the discomfort of the appearance of the hair itself, and to make the wearing part inconspicuous by blending the color with the own hair without discomfort, and it is possible to achieve a natural finish.

The length of the hair bundle 23 (hair body 23a) is arbitrarily set to a desired length and is not particularly limited, but is generally between about 10 and 50 cm and a plurality of patterns at intervals of 5 to 10 cm. It is molded to the length of.
The number of hair bodies 23a bundled as one hair bundle 23 is not particularly limited and can be appropriately increased or decreased as needed. For example, 50 to 100 hair bodies 23a can be used. One hair bundle 23 is formed by bundling.

The hair extension 10 according to the present invention formed by the above components is formed by binding hair bundles 23 to both end portions 21 of the yarn body 20, in other words, the two hair bundles 23 are the yarn body 20. It is a mode connected via. Regarding the binding mode between the end of the yarn body 20 and the hair bundle 23, the yarn body 20 is composed of a set of hair bodies 23a having a predetermined length tied to the yarn body 20 by a predetermined knot method, and the plurality of hair bodies 23a are the yarn body 20. The knot position is gradually shifted and tied to the end portion 21 of the yarn body 20, and the outline thereof is the mode shown in FIG. In the drawings, the knots are shown in a separated state so that it can be easily understood that the plurality of hair bodies 23a are tied by shifting the knot positions, but in reality, the knots are spaced apart. A plurality of hair bodies 23a are tied together in a state of being adjacent to each other without leaving a space.

By the way, the method of tying the hair body 23a to the yarn body 20 is not particularly limited, and is determined in consideration of both the strong binding property and the complexity of the binding work. That is, when only the strong cohesiveness is considered, the tying method becomes complicated and the tying work becomes complicated. On the contrary, if only the tying work is simplified by the simple tying method, the reliable tying force cannot be exhibited. Is assumed. Therefore, it is desirable to determine a knotting method that can achieve both of these, taking into consideration both the strong cohesiveness and the complexity of the bundling work. FIG. 3 shows an example of a binding method in consideration of the above points regarding how to tie the hair body 23a to the yarn body 20.

When the hair body 23a is tied to the thread body 20, the binding position in the hair body 23a is not particularly limited, but two main modes can be considered. The first is a mode in which the end portion of the hair body 23a is bound to the thread body 20, and the second is a mode in which the substantially central portion of the hair body 23a is bound to the thread body 20.

In the first aspect, by adopting the aspect of binding the end portion of the hair body 23a to the thread body 20, one hair body 23a directly constitutes one hair body 23a in the hair bundle 23. That is, the hair bundle 23 having the same number of hair bodies 23a as the number of tied hairs is formed. By performing such a binding mode at both end portions 21 of the yarn body 20, the two hair bundles 23 are connected via the yarn body 20. The end portion of the hair body 23a that is excessive at the knot is cut off if necessary. Further, the tips of the bundled hair bundles 23 are trimmed as necessary.

By adopting the first binding mode, it is possible to align the directions of the cuticles even when human hair is used for the hair body 23a. Then, the hair bundle 23 becomes a part of the yarn body 20 and is integrated, and the hair extension 10 in which the hair bundle 23 is firmly bound without falling off from the yarn body 20 is completed.

In the second aspect, by adopting the aspect of binding the substantially central portion of the hair body 23a to the thread body 20, one hair body 23a is folded back at the knot, and the second hair body 23a in the hair bundle 23 is used. That is, the hair bundle 23 having twice the number of tied hair bodies 23a is constructed. At this time, the positions of the thread body 20 and the hair body 23a are adjusted so that the substantially central portion of the hair body 23a is a knot with the thread body 20. By performing such a binding mode at both end portions 21 of the yarn body 20, the two hair bundles 23 are connected via the yarn body 20. The tips of the bundled hair bundles 23 are trimmed as necessary.

By the way, in the second aspect described above, since the hair body 23a is bound to the thread body 20 in a state of being folded back at a substantially central portion, the direction of the cuticle when human hair is used as the hair body 23a. It should be noted that one side becomes reverse hair at the turning point.
Further, in the second aspect described above, the length of the hair bundle 23 (hair body 23a) is substantially halved by folding back the hair body 23a at a substantially central portion, in other words, the desired hair. In order to obtain the length of the bundle 23, it is necessary to obtain the hair body 23a having twice the length by folding it back in the middle.

By adopting the second binding mode, the hair bundle 23 (hair body 23a) is folded back at a substantially central portion, so that the hair bundle 23 having twice the number of tied hair bodies 23a is configured. For example, 50 hair bodies 23a can be used to finally form a hair bundle 23 composed of 100 hair bodies 23a. In this way, since the number of hair bodies 23a is doubled by folding back, it is possible to reduce the amount of hair bodies 23a used, facilitate the bundling work, and shorten the time as compared with the conventional product. A feeling of volume can be produced even after mounting. Then, the hair bundle 23 becomes a part of the yarn body 20 and is integrated, and the hair extension 10 in which the hair bundle 23 is firmly bound without falling off from the yarn body 20 is completed.

Regarding the binding position (knot position) of the hair body 23a in the thread body 20, when all of the plurality of hair bodies 23a are bound at the same position of the thread body 20, the plurality of knots overlap at the binding position and the hair extension 10 Will be thicker than expected. On the contrary, it is conceivable to bind the hair bodies 23a with a large space between the knots so that the knots do not overlap, but then only a small number of hair bodies 23a are tied within a limited range at the end of the yarn body 20. It can be easily assumed that this will not be possible. Therefore, while shifting the binding position of each hair body 23a in the thread body 20 little by little, the plurality of hair bodies 23a are placed in the thread body 20 so that the knots are adjacent to each other without any gap. It is preferable to take a mode of binding to a plurality of places. In this way, at both ends 21 of the yarn body 20, the plurality of hair bodies 23a gradually shift the binding position (knot position) in the yarn body 20 and are tied to the end portion of the yarn body 20. It is possible to produce a natural voluminous feeling and a feeling of wearing at the time of wearing, and to create a natural finish. in fact

The hair extension 10 according to the present invention having the above configuration is attached to the own hair by using the portion of the thread body 20 and binding the hair extension 10 to a predetermined amount of the own hair. The specific method of connecting the thread body 20 and the own hair is not particularly limited, and the thread body 20 is firmly attached by a single knot or other inseparable knot and a method that does not come off.

As described above, the hair extension 10 according to the present invention can be easily and safely attached to the own hair by using the thread body 20 without using means such as heat fusion or adhesion, and can be attached to both ends of the thread body 20. Since the hair bundles 23 are tied together, the two hair bundles can be attached at the same time, which contributes to shortening the attachment time. It can realize a feeling of wearing, and can be easily and neatly removed, and contributes to the reuse of the hair extension 10 after removal.

Since the hair extension according to the present invention does not use metal or adhesive, it can be safely used by people with an allergic constitution to them, and can be used as a general purpose hair extension. In addition to the mode, it can be used as a partial wig for thinning hair and alopecia, and can be used as a hair extension for pets and dolls, and can be applied to a wide range of applications. Therefore, the industrial applicability of the "hair extension" according to the present invention is considered to be extremely large.
