JP7420691B2 - leaf vein extension - Google Patents

Description

The present invention relates to hair extensions that are attached to natural hair for the purpose of giving volume to the hair. More specifically, it relates to a leaf vein-like extension having a leaf vein-like appearance.

Conventional extensions have a metal tube attached to the base end of the hair bundle to be added, and the natural hair is inserted into the metal tube and the tube is crushed to attach it to the natural hair. What it does is known. In addition, a heat-shrinkable tube is coated on the outside of a cylindrical body made of a bundle of hair impregnated with adhesive, and the heat-shrinkable tube is heated with an iron or the like while the natural hair is inserted inside the cylindrical body. By doing so, devices that are attached to natural hair using a shrunk tube and molten adhesive have also been developed.

Patent Document 1 states, ``It can be attached to the natural hair very easily without damaging the natural hair, and it is difficult to remove because it has a high binding force on the natural hair, and moreover, it gives a sense of discomfort to the user even when lying down. The goal is to provide practical hair extensions that do not cause hair loss. The part 7) is embedded in the hair of the main body part 2 and is fixed to the main body part 2 by adhering it together with the hair with a binder.The string-like body 3 also has a part that can be pulled in a direction to separate the proximal end and the distal end. A first loop 5a and a second loop 5b, which are contracted by the first loop 5a and the second loop 5b, are formed so as to be spaced apart from each other by about 2.0 mm.'' Extension (Patent Document 1: Title of the Invention) is disclosed.

JP2011-236541A

The extension according to Patent Document 1 (Patent Document 1: Name of the Invention) is fixed to the main body 2 by embedding a knot (lump 7) in the hair of the main body 2 and bonding it together with the hair with a binder. In short, multiple human hairs are bundled in the same direction, and the 10 mm long base end of the bundle is glued together with a heat-resistant keratin-based binder (so-called keratin bond). Because the artificial hair is tied together, the starting points of the artificial hair are lined up side by side, giving the appearance of artificially increasing hair. In other words, the extensions according to Patent Document 1 It is hard to see that it grows naturally on the human head.

The purpose of the present invention is that it is not necessary to attach an adhesive to the natural hair, and there is no need to use any adhesive at all in the manufacturing process, so that it can be manufactured efficiently, and the starting point of the artificial hair can be Vein-like extensions that can be worn in a natural-looking manner (i.e., can be worn to give the impression that natural hair is growing naturally on a person's head) because their positions can be distributed Our goal is to provide the following.

In order to solve the above problem, the invention described in claim 1 is a method for manufacturing an extension, in which the attachment means for attaching to natural hair is a string-like body , wherein the extension is It is made of fibers with a thickness of 53 d to 10,630 d, and 10 to 30 bundles of human hair are tied to a predetermined length at one end of the string-like body. The 10 to 30 hair bundles are formed by separating and tying, and the 10 to 30 hair bundles protrude from the string-like body alternately to the left and right along the longitudinal direction of the string-like body, with the knot in the middle. A knob is formed on the other end side of the string-like body through which a finger is inserted when pulling the string-like body, and on the side of the hair bundle from the knob, A first loop and a second loop are provided which are contracted by pulling the proximal end and the distal end of the string apart, and each of the hair bundles is formed into the string by the steps (a) to (d) below. It is characterized by being tied to the body .
(a) Step of setting a bundle of 3 to 5 human hairs on the lower side of the string-like body by folding it back once to form a first fold in a substantially U-shape.
(b) Pass one edge of the hair bundle from the lower side of the string-like body to the upper side, and pass the other end edge of the hair bundle from the lower side of the string-like body to the upper side, and then fold the hair bundle into the first fold. , and then folded back to form a substantially U-shaped second fold that protrudes further outward than the first fold. The process of passing the bottom of the tip and passing the top of the string-like body
(c) move one tip of the hair bundle from the outside of the first fold and below the tip of the second fold to the space formed by the second fold and the first fold; The process of pulling both ends of the hair bundle after passing through the inside.
(d) After tying each hair bundle to a string-like body, the position of the knot of the hair bundles is moved along the string-like body and brought together near one end of the string-like body.
Note that the hair in this specification may be human hair or artificial hair such as fiber.

The hair extensions manufactured by the manufacturing method of the present invention have a hair bundle of 3 to 5 hairs, a hair bundle length of 30 cm to 50 cm, and a length between hair bundles of 0. It may be .1 mm to 0.2 mm.

The vein-like extensions described in the present invention can be applied using conventional methods (using a sheet-like sticker, weaving into the roots of natural hair, attaching using ultrasonic waves, small cylindrical beads, etc.). Unlike other methods (such as threading the hair through the hair and fixing it with pliers, etc.), extensions use a string-like body as a means of attaching the hair to the natural hair. Therefore, it can be attached to the natural hair very easily without damaging the natural hair, and it is difficult to remove because the natural hair has a high binding force, and it is practical because it does not cause discomfort to the user even when lying down. extensions can be provided.

In addition, the vein-like extension according to the present invention is formed by tying together hair bundles of a plurality of hairs at a predetermined distance apart from one end of the string-like body. The extension according to Patent Document 1 is formed by bundling about 300 human hairs with a length of about 300 mm, and is integrated by bonding the base end of the bundle with a length of about 10 mm using a binder. Since the hair is formed in one place, the base ends of many hairs are aligned laterally (in one place) when worn, giving an unnatural feeling. In contrast, with the vein-like extensions according to the present invention, the base end of the hair is in a different position when worn, creating a state similar to that of hair growing from the scalp, so the condition of the hair when worn is can be made to feel more natural.

They are an overall view and a partially enlarged view of a leaf vein-like extension. FIG. 3 is an explanatory diagram showing a method for producing leaf vein-like extensions. FIG. 3 is an overall view before attachment of leaf vein extensions. FIG. 2 is an explanatory diagram showing a state in which vein-like extensions are attached to natural hair.

<Structure and manufacturing method of leaf vein extension>
Hereinafter, one embodiment of the vein-like extension 1 according to the present invention will be described in detail based on FIGS. 1 to 4. FIG. 1 is an overall view and a partially enlarged view of a leaf vein-like extension 1 according to the present invention.

As shown in FIG. 1, the vein-like extension 1 according to the present invention is obtained by bundling and tying a plurality of hairs 3 to each location separated by a predetermined length near one end of the string-like body 2. The leaf vein-like extension 1 is characterized by the fact that it is formed, and looks like leaf veins (vascular lines running on the leaf surface) in appearance.

As shown in the enlarged view of FIG. 1, a plurality of hairs 3 (which may be human hair or artificial hair such as fibers) are attached to one end of the string-like body 2 at a predetermined distance apart, as shown in the enlarged view of FIG. ) are tied together (we will explain how to tie them later). The predetermined length (the distance between the center of one knot and the center of an adjacent knot) is usually 1 mm or less, but depending on your preference, you can leave a gap of 1 mm or more, or the width of the gap can be set randomly (0. 5 mm to 1.5 mm). Note that the number of hairs 3 forming one knot 4 is 3 to 5, and the length of the hairs 3 is 30 cm to 50 cm. A knot 4 formed when the hair 3 is tied to the string-like body 2 is tied so as to be approximately in the middle of the hair 3 and movable along the string-like body 2. Further, as shown in FIG. 1, the hair 3 is allowed to flow so as to spread alternately from side to side at each knot 4 around the string-like body 2.

FIG. 2 is an explanatory diagram showing a method for producing the vein-shaped extension 1 (that is, an explanatory diagram showing a method for tying the hair 3 to the string-like body 2 of the vein-shaped extension 1). Note that in this specification, for convenience of explanation, it is unavoidable that the expression is two-dimensional, but the actual work is performed in a three-dimensional space.

First, as shown in FIG. 2(a), hair 3 (3 to 5 hairs tied together) is folded back once and set on the underside of the string-like body 2. When viewed from the tip of the fold, the right tip of the hair 3 is (α), the left tip of the hair 3 is (β), and the tip of the fold is (γ). Start the tying work from this state.

Then, as shown in FIG. 2(b), the right end (α) of the hair 3 is passed from the lower side of the string-like body 2 to the upper side, and the left end (β) of the hair 3 is passed through the string-like body 2. Pass it from the bottom side of the body 2 to the top side, pass the bottom side of (γ), then turn it back (denoted as γ') and pass it under (γ) again, and pass the top side of the string-like body 2. Let it pass.

Furthermore, as shown in FIG. 2(c), the right end (α) of the hair 3 is passed between (γ) and (γ'). By pulling both ends of αβ, a knot is finally formed as shown in FIG. 2(d), completing one tying operation. When actually producing the vein-like extension 1, this operation will be repeated many times. That is, this process is repeated approximately 10 to 30 times at adjacent locations along the string-like body 2. After the hair 3 is tied to the string-like body 2, the position of the knot 4 is freely moved along the string-like body 2 and gathered near one end of the string-like body 2.

<How to use leaf vein extensions>
FIG. 3 is an overall view of the leaf vein extension 1 before it is attached. The vein-like extension 1 is formed by bundling and tying a plurality of hairs 3 to each end of a string-like body 2 at a predetermined length. As shown in FIG. 3, on the other end side of the string-like body 2, there is a knob 5 with an inner circumference of about 90 mm through which a finger is inserted when pulling the string-like body 2 to bind the string-like body 2. is formed by.

By binding the string-like body 2, the first loop 6 and the second loop 7, which are contracted by pulling the proximal end and the distal end of the string-like body 2 in the direction of separating them, are positioned at a predetermined distance apart. It is formed to do so. The string-like body 2 is made of fibers whose main component is cotton and has a thickness of 53 d to 10,630 d, and the inner circumference lengths of the first loop 6 and the second loop 7 are 5.0 mm to 13 mm. It is adjusted to be .0mm.

FIG. 4 is an explanatory diagram showing a state in which the vein-like extension 1 is attached to the natural hair H. When attaching the vein-shaped extension 1 to natural hair H (that is, the user's own hair), bundle a predetermined amount (approximately 50 hairs) of natural hair H, H, etc., and insert the inside of the second loop 7. After the insertion, the inside of the first loop 6 is inserted (see FIG. 4). In addition, when the natural hair H, H, etc. are inserted through the second loop 7 and the first loop 6, a tool such as a crochet hook can be suitably used.

Thereafter, while grasping the proximal end of one end of the string-like body 2, pull the knob 5 of the string-like body 3 outward. When the string-like body 2 is pulled in this way, the first loop 6 and the second loop 7 are twisted so as to rotate relative to each other while slightly expanding the distance between them, and the first loop 6 and the second loop 7 are twisted so as to rotate relative to each other. The diameter of the loop gradually decreases (that is, the first loop 6 and the second loop 7 contract (see FIG. 4)).

When the first loop 6 and the second loop 7 contract while twisting each other, the natural hair H, H... forms a spiral of about 180 degrees between the first loop 6 and the second loop 7. While drawing, it is held by the first loop 6 and the second loop 7 while being bent to match the unevenness of the string-like body 2 (the unevenness formed by binding). Therefore, the natural hair H, H, . . . passed through the first loop 6 and the second loop 7 is held with an extremely high binding force.

As described above, after the natural hair H, H, etc. are gripped by the first loop 6 and second loop 7 of the string-like body 2, the outer side of the contracted first loop 5a and second loop 5b is By cutting the string-like body 2, attachment to the hair is completed.

<Effects of leaf vein extensions>
Conventional extensions can be broadly divided into two methods: braiding into the natural hair, sheet-like extensions using a sheet-like seal to attach the extensions to the natural hair, and 3mm to 5mm in diameter and 5mm to 15mm in length. There was one in which natural hair and extensions were passed together through a heat-shrinkable tube, and the extensions were attached using the heat-shrinkable tube and adhesive using heat from a hair iron, etc.

Braided hair extensions have stitches, so the part where the hair is braided ends up looking bumpy, which makes it feel uncomfortable in the area where it's attached. Seal extensions don't feel bumpy to the touch, but when removing them, you have to use a special remover or nail polish remover that contains acetone, which can damage the scalp. Another problem is that the mounting strength is weak. In addition, ingredients contained in shampoos, treatments, etc., as well as oil from the scalp, weaken the bond. Furthermore, it is sensitive to heat, so hair dryers and curling irons are also limited.

The vein-shaped extension 1 according to the present invention fundamentally reviews these conventional methods, and is an epoch-making method that is easy to install, has sufficient strength, and does not feel uncomfortable. It is an extension. That is, the vein-like extension 1 is formed by bundling and tying a plurality of hairs 3 at one end of the string-like body 2, separated by a predetermined length. The extension according to Patent Document 1 is formed by bundling about 300 human hairs with a length of about 300 mm, and is integrated by bonding the base end of the bundle with a length of about 10 mm using a binder. However, in such extensions, the hair 3 is formed in one place, so when it is installed, the base ends of many hairs are aligned laterally (in one place), which gives an unnatural feeling. . On the other hand, in the vein-shaped extension 1 according to the present invention, the base ends of the hairs (each hair bundle) 3 are at different positions when worn, so a state similar to that of hair growing from the scalp is created, The condition of the hair becomes more natural when worn.

<Example of changing extension>
The vein-shaped extension according to the present invention is not limited to the aspects of each embodiment described above, and the structure of the string-like body, hair, knot, etc. may be modified as necessary without departing from the spirit of the present invention. It can be changed as appropriate.

Since the vein-like extensions according to the present invention exhibit excellent effects as described above, they can be suitably used as so-called hair extensions for adding volume to hair.
