Patent Application
20210235800
The present invention relates to artificial hair, an artificial hair unit, and a method for attaching artificial hair.
One conventional method for changing women's hairstyles is to attach weaving.
When attaching weaving, hair of a user is braided in cornrows, and hung-down-fiber (fiber group) are sewn onto this braided part. Weaving can be therefore attached in accordance with a size of the head of the user, without any concern about misalignment or detachment, allowing fine modifications of parting, weights, and the like.
Since there is only a slight gap in the braided (knitted) part of base hair in the case of attaching the hung-down-fiber, conventionally a sharp needle is used to thread the hung-down fiber itself. Then, the braided part is threaded with a sharp needle to attach the hung-down fiber to the braided part. In this case, the sharp needle is used, and the sharp needle may be mistakenly pierced into a scalp when threading through the braided part of the base hair.
Thus, in recent years, a jig dedicated to threading the braided (knitted) part of the base hair has been developed (for example, Patent Document 1).
Patent Document 1: JP 6312514 B2
However, the jig in Patent Document 1, which has a large diameter at a distal end, is difficult to pass through generally-used hung-down-fiber. Further, when the hung-down-fiber itself is passed through the jig, a sharp needle is used, and the attachment of the hung-down-fiber to the braided part is troublesome.

Within this range, the first linear part 15 is inconspicuous while ensuring sufficient strength.
A maximum diameter of a circle enclosed by an opening of each annular part 20 is preferably 1.5 mm or more and 2 cm or less.
Within this range, the attachment string 5 can be easily passed through and the opening is inconspicuous.
The lower folded part 31 is a part that is folded back in an arc shape from the return connecting part 33 toward the forward connecting part 32.
Each annular part 20 is stretchable in an extending direction, and its length is preferably stretchable to 1.05 times or more with no load applied. That is, a diameter of the opening of each annular part 20 is preferably expandable.
The second linear part 16 is a linear body meandering in the vertical direction similarly to the first linear part 15. The second linear part 16 includes an upper folded part 40, a lower folded part 41, a forward connecting part 42 extending linearly from the lower folded part 41 toward the upper folded part 40, and a return connecting part 43 extending linearly from the upper folded part 40 toward the lower folded part 41.
The second linear part 16 is located entirely above the first linear part 15, and extends while maintaining substantially parallel. That is, in the second linear part 16, the upper folded part 40 is folded back in an arc shape, and the second linear part 16 extends so as to surround each annular part 20 from outside the first linear part 15 when viewed from a front. The upper folded part 40 configures an annular part 21 together with the first fiber group 11 and the second fiber group 12.
As shown in
The upper folded part 50 includes two bent parts 55 and 56 and a connecting part 57 connecting the bent parts 55 and 56. That is, the upper folded part 50 is connected to the return connecting part 53 from the forward connecting part 52 via the bent part 55, the connecting part 57, and the bent part 56. The upper folded part 50 configures an annular part 22 together with the first fiber group 11 and the second fiber group 12.

The fiber bundle 60 is fibers that imitate hair and includes bendable linear fibers.
Examples of fibers configuring the fiber bundle 60 include flame-retardant fibers such as collagen protein fibers, vinyl chloride fibers, vinylidene chloride fibers, acrylic fibers, and flame-retardant polyester fibers, and natural hair such as human hair and animal hair. In particular, as the fibers configuring the fiber bundle 60, KANEKARON (registered trademark) manufactured by KANEKA CORPORATION can be favorably used for its self-extinguishing property, unlikeliness to cause melting and drip, and excellent dyeability and color developing property.
A part around one end of the fiber bundle 60 is folded back a plurality of times and sewn together with the other fiber bundles 60, and this folded part configures the connecting part 61.
The connecting part 61 is a part connecting each fiber bundle 60, and spreads in a plane shape.
Here, a positional relationship of each part of the artificial hair 2 will be described.
As will be described later, the attachment part 10 is partially sandwiched between the fiber groups 11 and 12 and sewn. Specifically, each of the linear parts 15 to 17 is sandwiched between the fiber groups 11 and 12, and is directly sewn and attached thereto.
The first fiber group 11 partially overlaps with the second fiber group 12 when viewed from a front. The fiber bundle 60 of the first fiber group 11 is located between the adjacent fiber bundles 60 and 60 of the second fiber group 12.
As shown in
The linear parts 15 to 17 extend in and out in the longitudinal direction Y from between the fiber groups 11 and 12, and a part of the annular parts 20 to 22 is exposed to outside from the fiber groups 11 and 12. It can be said that the upper folded parts 30, 40, and 50 are external folded parts that are folded outside the fiber groups 11 and 12, and the lower folded part 31, 41, are 51 are internal folded parts that are folded inside the fiber groups 11 and 12.
The linear parts 15 to 17 overlap in the lateral direction X with substantially no gap between the first fiber group 11 and the second fiber group 12.

The forward connecting part 52 and the return connecting part 53 of the third linear part 17 are located between the return connecting part 33 of the first linear part 15a and the forward connecting part 32 of the first linear part 15a. That is, the forward connecting part 52 and the return connecting part 53 of the third linear part 17 fill a gap between the return connecting part 33 of the first linear part 15a and the forward connecting part 32 of the first linear part 15a.
From another point of view, the forward connecting part 42 and the return connecting part 43 of the second linear part 16 function as gap closures that fill the gap between the forward connecting part 32 of the first linear part 15b and the return connecting part 33 of the first linear part 15a adjacent to the first linear part 15b in the lateral direction X. The forward connecting part 52 and the return connecting part 53 of the third linear part 17 function as gap closures that fill the gap between the return connecting part 33 of the first linear part 15a and the forward connecting part 32 of the first linear part 15a.
A part of the second linear part 16 is disposed between the connecting parts 33 and 32 of the first linear parts 15a and 15b adjacent to each other in the lateral direction X outside the first linear part 15, and is substantially flush with the connecting parts 33 and 32.
The end of the third linear part 17 is disposed between the connecting parts 32 and 33 of the first linear parts 15 adjacent to each other in the lateral direction X outside the second linear part 16, and is substantially flush with the connecting parts 32 and 33.
That is, in the linear parts 15 to 17, the connecting parts 32, 33, 42, 43, 52, and 53 configure flat parts 65 and 65 on front and reverse, respectively.
The first linear part 15 and the second linear part 16 are provided so as not to overlap three-dimensionally. On the other hand, in the third linear part 17, exposed parts exposed from the fiber groups 11 and 12 three-dimensionally intersect with the first linear part 15 and the second linear part 16.
The third linear part 17 straddles the openings of the adjacent annular parts 20 and 20. That is, the upper folded part 50 of the third linear part 17 extends such that the connecting part 57 crosses the connecting parts 32, 42, 43, and 33 and three-dimensionally intersects with the connecting part 32, 42, 43, and 33.
The connecting parts 61 and 61 of the fiber groups 11 and 12 sandwich the flat parts 65 and 65 of the attachment part 10. The connecting part 61 of the first fiber group 11 is in surface contact with the flat part 65 on one side of the attachment part 10. The connecting part 61 of the second fiber group 12 is in surface contact with the flat part 65 on the other side of the attachment part 10. The artificial hair 2 is sewn with a thread or the like at an overlapping part of the connecting part 61 and the flat part 65.
As shown in

An outer shape of a cross section of the attachment string 5 is, for example, circular (or elliptical), and an outer diameter of the attachment string 5 is preferably 0.1 mm or more and 6.0 mm or less.
The outer diameter of the attachment string 5 according to one or more embodiments is about 3 mm, which is larger than an outer diameter of a general sewing thread.
A material of the attachment string 5 is not limited, and may be a natural fiber such as silk thread or cotton thread, or a synthetic fiber such as nylon or polyester.
In one or more of the present embodiments, the attachment string 5 is woven into a mesh shape so as to be stretchable and has a tubular shape.
Next, a treatment method (method for attaching the artificial hair 2) recommended when the artificial hair unit 1 is treated to the user will be described.
First, the artificial hair 2 is attached to the cap member 3 with the attachment string 5.
Specifically, as shown in
Subsequently, the intermediate part 80b of the attachment string 5 is hooked by the jig 90 to form a second folded part 81b. The second folded part 81b is passed through a gap 72b of the braided part 71, and through second annular parts 20b, 21b, and then through the first folded part 81a. That is, the second folded part 81b is passed through the first folded part 81a outside the second annular parts 20b and 21b when viewed from the braided part 71.
Subsequently, the intermediate part 80c of the attachment string 5 is hooked by the jig 90 to form a third folded part 81c. The third folded part 81c is passed through a gap 72c of the braided part 71, and through third annular parts 20c and 21c, and then through the second folded part 81b. That is, the third folded part 81c is passed through the second folded part 81b outside the third annular parts 20c and 21c when viewed from the braided part 71.
This is repeated to attach the artificial hair 2 to the cap member 3 with the attachment string 5, and an end of the attachment string 5 is firmly fixed to the cap member 3.
In the artificial hair unit 1 according to one or more embodiments of the present invention, the plurality of annular parts 20 are provided, and the attachment string 5 can path through the annular parts 20. Thus, the artificial hair unit 1 can be safely attached to the head 200 of the user by passing a thread or string through the annular parts 20 and attaching the thread or string to the cap member 3 without passing a sharp needle.
In the artificial hair 2 according to one or more embodiments of the present invention, the attachment part 10, which includes a braid or weaving, can be easily provided.
In the artificial hair 2 according to one or more embodiments of the present invention, the annular parts 20 are aligned in parallel in the lateral direction X, and the openings face the thickness direction which is a direction intersecting with the lateral direction X. Thus, the attachment string 5 can be passed through each annular part 20 with the artificial hair 2 spread, and the attachment string 5 can be easily passed through each annular part 20.
In the artificial hair 2 according to one or more embodiments of the present invention, the fiber bundle 60 of the first fiber group 11 is located between the fiber bundles 60 of the second fiber group 12 when viewed from a front. It is therefore possible to show an amount of fibers (hair amount) larger than it is.
In the artificial hair 2 according to one or more embodiments of the present invention, the attachment part 10 includes a plurality of linear bodies, and the linear bodies are directly sewn to the fiber groups 11 and 12 to attach the attachment part 10. That is, a base for attaching the attachment part 10 to the fiber groups 11 and 12 is not provided, thereby reducing costs and making a good design.
In the artificial hair 2 according to one or more embodiments of the present invention, the first linear part 15 is sandwiched between the fiber groups 11 and 12 and sewn while meandering, and a part of the first linear part 15 is exposed to outside from between the fiber groups 11 and 12. The exposed part of the first linear part 15 configures each annular part 20 together with the fiber groups 11 and 12. Therefore, each annular part 20 can be configured by one first linear part 15, thereby reducing the costs.
In the artificial hair 2 according to one or more embodiments of the present invention, the second linear part 16 and the third linear part 17 are located between the fiber groups 11 and 12 and function as gap closures that fill the gap between the forward connecting part 32 and the returning connecting part 33. Thus, the second linear part 16 and the third linear part 17 configure the flat part 65 together with the forward connecting part 32 and the return connecting part 33, and the flat part 65 functions as a base for attaching the attachment part 10 to the fiber groups 11 and 12. This facilitates attachment of the fiber groups 11 and 12.
In the artificial hair 2 according to one or more embodiments of the present invention, a part of the second linear part 16 is disposed between the forward connecting part 32 and the return connecting part 33 of the first linear parts 15 adjacent to each other outside the first linear part 15, and is substantially flush with the forward connecting part 32 and the return connecting part 33. This can reduce the thickness of the artificial hair 2 as a whole when the fiber groups 11 and 12 are overlapped with the attachment part 10.
In the artificial hair 2 according to one or more embodiments of the present invention, in the second linear part 16, the exposed part exposed from the fiber groups 11 and 12 is outside the first linear part 15, and the second linear part 16 extends so as to surround each annular part 20 along the first linear part 15. That is, a double structure of the first linear part 15 and the second linear part 16 allows the second linear part 16 to hold the artificial hair 2 with the attachment string 5 by passing the attachment string 5 through the annular parts 20 and 21 even when the first linear part 15 is cut.
In the artificial hair unit 1 according to one or more embodiments of the present invention, in order to attach the artificial hair 2 to the cap member 3, for example, the artificial hair 2 is attached to the cap member 3 and then the cap member 3 is fixed to the head 200 of an operated person, thereby allowing safer treatment.
In the artificial hair unit 1 according to one or more embodiments of the present invention, the attachment string 5 is stretchable in the longitudinal direction, and thus the attachment string 5 extends to prevent an excessive load from being applied to the braided part 71 when the artificial hair 2 is pulled.
In the artificial hair unit 1 according to one or more embodiments of the present invention, the attachment string 5 is untied by releasing an end of the attachment string 5 and pulling the attachment string 5, and thus the artificial hair 2 can be easily attached to and detached from the cap member 3. That is, in the artificial hair unit 1 according to one or more embodiments of the present invention, when it is desired to re-do the sewing, it is possible to easily re-do the sewing as many times as necessary.
In one or more embodiments of the present invention, the artificial hair 2 is attached to the cap member 3 and then the cap member 3 is attached to the head 200, but one or more embodiments of the present invention are not limited thereto. The artificial hair 2 may be attached to the cap member 3 after the cap member 3 is attached to the head 200.
In one or more embodiments of the present invention, the cap member 3 entirely covers the head 200, but one or more embodiments of the present invention are not limited thereto. The cap member 3 may partially cover the head 200.
In one or more embodiments of the present invention, a case has been described where the attachment part 10 is a braid or weaving including three types of linear parts 15 to 17, but one or more embodiments of present invention are not limited thereto. As long as the braid or weaving has the annular parts 20, another form of braid or weaving can also be used as the attachment part 10. For example, as shown in
In one or more embodiments of the present invention, the artificial hair 2 is attached to the cap member 3 and the cap member 3 is fixed to the hair of the head 200 of the user to fix the artificial hair 2 to the head 200 of the user, but one or more embodiments of the present invention are not limited thereto. The artificial hair 2 may be attached directly to the hair of the user.
Although the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that various other embodiments may be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the attached claims.
