Description

Description Self-hair bundle · Hair bundle binding structure and hair bundle · Hair bundle binding method for hair Technical Field

The present invention relates to a method for attaching a fiber bundle for hair, and more particularly, to a method for attaching a fiber bundle for human hair or artificial hair to human hair. Background art

Generally, in order to arbitrarily change the length and amount of hair, a method of attaching a fiber bundle for hair to the hair has been adopted. Hair fiber bundles are called hair extensions, and are made of human hair and those made of synthetic fibers such as polyethylene.

Fiber bundles for human hair made with human hair originally use human hair, so the texture is natural and easy to adjust to the natural hair, and there is little discomfort when it hits the skin. Can be processed. On the other hand, fiber bundles for human hair made of synthetic fibers such as polyethylene are cheaper in price, compatible with the hair color of the seeds, and have little change in quality. Each bundle of bundles and synthetic fiber bundles for hair has advantages, and is selected and used according to the needs of users. The above-mentioned fiber bundles for human hair or artificial hair are attached to the hair and are used when the entire hair is worn longer than the own hair, or when it has a more polymer feel than the own hair. Generally, it is attached by fixing by braiding a part of the hair or by fixing with a metal fitting. Of the methods of attaching hair fiber bundles to hair, fixing by braiding into a part of the hair generally involves attaching the hair fiber bundles by braiding such as three or four braids.

As a general method of attaching a fiber bundle for hair by braiding (the following is a case of four braids), first, several self-hairs within a few millimeters to a centimeter square of the scalp are separated, and the self-hairs Is divided into two on the left and the right.

Then, the fiber bundle for hair is placed near the scalp between the root part of the hair bundle A and the root part of the hair bundle B.

Next, the hair bundles A and B are crossed over the fiber bundle for hair. At that time, the intersection of the hair bundles A and B is arranged on the upper surface of the fiber bundle for hair.

After that, the upper and lower parts of the fiber bundle for hair use the intersection of the hair bundles A and B as fulcrums. As described above, the upper part of the hair fiber bundle and the lower part of the hair fiber bundle are crossed on the crossing part of the own hair bundles A and B. At that time, the upper part and the lower part of the hair fiber bundle are arranged on the upper surface of the cross part of the own hair bundles A and B.

Then, the self-hair bundles A and B are crossed again, and the second crossing portion of the self-hair bundles A and B is arranged on the upper surface of the upper and lower cross portions of the hair fiber bundle. The upper part and the lower part are crossed, and the upper part and the lower part of the hair fiber bundle are arranged on the upper surface of the second crossing part of the hair bundles A and B. Similarly, the above process is repeated several times, and the final intersection is bound with a rubber thread or the like. The above-mentioned attachment method by braiding allows the fiber bundle for hair to be securely fixed to the own hair, and is difficult to remove, and the amount of the fiber is easy to adjust freely. However, there was a problem that the braid was able to be fixed to the own hair reliably, so that during the knitting work, the pull on the own hair was strong and painful. In addition, the braiding technique requires skill, and if it is not possible, it will come off immediately after attaching the fiber bundle for hair, or the braided part will be released. There is also a problem that it takes time to work.

Furthermore, when removing the hair fiber bundle, the hair and the fiber bundle may be tangled, which is painful and may damage the hair. On the other hand, for fixing with the metal fitting, after the annular metal fitting is inserted into the own hair, the hair fiber bundle is passed through the same annular metal fitting, and the hair is sandwiched between the hair fiber bundles and then placed in the metal fitting. This is a method of flattening and fixing the bracket.

This method allows the hair fiber bundle to be attached by one person, and does not require complicated work such as braiding. Can be attached.

For example, the “extension mounting method” disclosed in Japanese Patent Laid-Open No. 2 0 0 4-1 5 6 1 5 7 discloses an extension, a bar for hooking the extension, a ring for fixing the extension, and crushing the ring. This is a method of attaching an extension using a nipper.

The mounting method includes a first step of inserting a bar with a force needle into the ring, a second step of hooking hair into the key needle, a third step of removing the inserted bar from the ring, Insert the par into the ring again and hook the extension into the key needle.Fifth step to remove the inserted bar from the ring. It consists of the sixth step.

Reference: Japanese Patent Laid-Open No. 2 0 0 4-1 5 6 1 5 7 However, the attachment using the metal fittings (rings) as described above has a fixed size, so the amount of fibers in the fiber bundle for hair cannot be adjusted arbitrarily, and the metal fittings are easy to loosen. Therefore, there was a problem that it was easy to remove. Furthermore, since the metal fitting is located near the scalp, there is a sense of incongruity, and there is a problem that the metal fitting rubs with other self hair and the self hair is cut off.

Also, when going to bed, the metal part hits the head, so it may be difficult to sleep or cause pain.

And when removing the fiber bundle for hair, it is necessary to deform and remove the metal fittings, which takes time and technology. Disclosure of the invention

The present invention relates to a binding structure of a self-hair bundle, a fiber bundle for hair, and a method for binding a self-hair bundle to a fiber bundle for hair, and a self-hair bundle formed by separating a plurality of self-hairs from a part of the scalp surface. It is a self-hair bundle / fiber bundle bundle for hair, in which the joints of the fiber bundles for hair to be fixed are joined together by winding a tape with an adhesive and an adhesive. And the hair bundle Hair bundles and hair fibers in which the base of the hair and one end of the fiber bundle for hair are bonded via a binder or adhesive, and a tape with adhesive is wrapped around the outer peripheral surface of the bonded portion of both bundles It is a bundle coupling method.

In the self-hair bundle / hair fiber bundle bonding structure and bonding method of the present invention, as the self-hair bundle formed by separating a plurality of self-hairs from a part of the scalp surface, for example, the scalp surface l to 20 mm square The self-hair bundle is made by separating the own hair from the scalp surface of 5 to 15 mm square, and the self-hair bundle and the fiber bundle for hair are combined. The part is formed at a position of 0.5 to 5 cm, preferably 1 to 3 cm from the scalp surface, that is, from the root of the hair bundle. In the present invention, the fiber bundle for hair is a fiber bundle that can be attached to the own hair, such as a fiber bundle for hair composed of human hair, a fiber bundle for artificial hair made of synthetic fibers such as polyethylene, The material is not limited.

And the self-hair in the present invention is hair growing from the scalp, but according to the present invention, for example, the hair increased on the surface of the scissors scalp is used as the self-hair and combined with the fiber bundle for hair. You can also. In the self-hair bundle / hair fiber bundle bonding structure and bonding method in the present invention, the amount of self-hair separated from a part of the scalp surface is not limited, so that it matches the amount of hair fiber bundle to be combined, It is desirable to make a hair bundle by selecting it appropriately and separating it from the scalp. As mentioned above, if the hair is separated from the scalp surface of about 1 to 20 mm square, especially 5 to 15 mm square, and the hair bundle is made, the fiber bundles for hair are naturally bound when finished. This is preferable.

In addition, the pressure-sensitive adhesive tape used in the self-hair bundle / hair fiber bundle bonding structure and bonding method in the present invention is preferably made of cloth or non-woven fabric, and further has elasticity. The tape preferably has a width of 1 to 8 mm and a length of 15 to 50 mm, particularly preferably a width of 2 to 5 mm and a length of 20 to 40 mm.

The adhesive tape made of cloth or non-woven fabric shrinks when washing the eyelids or gets wet with sweat, so the binding between the hair bundle and the fiber bundle for hair becomes stronger and the water repellency is high. It is quick-drying and does not cause discomfort to the wearer.

In addition, the adhesive tape can be either stretchable or non-stretchable, but in the case of a stretchable adhesive tape,

• Because the fiber bundle binding portion for hair is deformed and deforms following the various shapes of the joint portion during binding work, the hair bundle for hair and the fiber bundle for hair are hard to come off, making the binding work easy and The rise is a beautiful joint. Furthermore, in the self-hair bundle / hair fiber bundle bonding structure and bonding method in the present invention, a tape with a pressure-sensitive adhesive having a colored end can be used.

The tape with the pressure-sensitive adhesive colored at the end is a tape with pressure-sensitive adhesive colored at the position that becomes the final edge when wound around the outer peripheral surface of the joint portion. By using this, the end can be easily and easily removed when removing the hair fiber bundle from the hair bundle. The coloring color is preferably white, which is easily recognized during work. In the present invention, the binder or adhesive used for bonding the hair bundle and the fiber bundle for hair is not particularly limited as long as the hair bundle and the fiber bundle for hair can be bonded. For example, polyethylene, polypropylene Such as olefin resins, polyvinyl chloride, polyvinyl acetate, polyamide, polyethylene terephthalate, polyphenylene sulfide, and more preferably keratin resins and gelatin adhesives. Also, resin prepolymers (including a small amount of hardener) can be used. Further, the resin may be a photopolymer resin prepolymer, and the curing operation may be performed by irradiating with ultraviolet rays or visible light instead of the ultrasonic waves. In the self-hair bundle / hair fiber bundle bonding method in the present invention, it is preferable that the binder or adhesive used for bonding the self-hair bundle and the hair fiber bundle is melted or polymerized and cured by a heating means. As a heating means, a heating instrument such as a commercially available ultrasonic welding (adhesion) machine can be adopted, and it is not particularly limited. The ultrasonic welding machine melts or heats a hot-melt resin or thermoplastic resin employed as the binder or adhesive by applying ultrasonic vibration energy.

In particular, the solidified hot-melt resin or thermoplastic resin previously applied to a part of the fiber bundle for hair melts by melting by heating and dissolves in the vicinity of the contact portion between the own hair and the hair fiber. And then solidify by allowing to cool, and the self-hair bundle and the fiber bundle for hair are firmly bonded, so it is possible to work without soiling hands and hair with adhesive etc. rather than using a liquid adhesive, And even if you are not a skilled person, you can work with a reliable connection. Moreover, when using the said heating means, a binding agent and an adhesive can use a thing hardened | cured by heating, and can bind | bond a hair bundle and a fiber bundle for hair firmly.
