Abstract

Provided are an artificial hair and an artificial hair unit that are easier to attach to a head of a user, a wig cap, or the like, and a method for attaching the artificial hair. The present invention provides a configuration including at least two fiber groups and an attachment part having a plurality of annular parts. The two fiber groups spread at least in a first direction, where the attachment part extends in the first direction and is sandwiched between the two fiber groups and sewn onto the two fiber groups, and where the plurality of annular parts are exposed to an outside from between the two fiber groups.

First claim

The invention claimed is:

1. A hair attachment comprising:
at least two fiber groups spread in a first direction; and
an attachment part having a plurality of annular parts, wherein the attachment part extends in the first direction,
wherein:
the attachment part includes a flat part,
the at least two fiber groups include a connecting part,
the flat part is sandwiched between the two fiber groups to contact with the connecting part in surface and is sewn onto the two fiber groups,
the annular parts are exposed to an outside from between the two fiber groups,
the attachment part includes a first linear part that configures the annular parts,
the first linear part includes:
an external folded part that is folded outside the at least two fiber groups;
a forward connecting part directed from between the two fiber groups toward the external folded part; and
a return connecting part directed from the external folded part toward between the two fiber groups,

the hair attachment includes a gap closure disposed between the at least two fiber groups, the gap closure filling a gap between the forward connecting part and the return connecting part in the first direction, and
the gap closure is flush with the forward connecting part and the return connecting part.

2. The hair attachment according to claim 1 , wherein the attachment part is a braid or a weaving.

3. The hair attachment according to claim 1 ,
wherein each of the annular parts have an opening, and
wherein the opening encloses a circle having a maximum diameter, wherein the maximum diameter is 1.5 mm or more and 2 cm or less.

4. The hair attachment according to claim 1 , wherein the annular parts are aligned in parallel to the first direction and have an opening facing a direction different from the first direction.

5. The hair attachment according to claim 1 , wherein
each of the annular parts include a linear body, and
the linear body has an arithmetic mean width of 0.5 mm or more and 3 mm or less.

6. The hair attachment according to claim 1 , wherein the plurality of annular parts includes a linear body and is stretchable in an extending direction.

7. The hair attachment according to claim 1 ,
wherein the at least two fiber groups include a first fiber group and a second fiber group,
wherein the first fiber group and the second fiber group each have fiber bundles in which a plurality of fibers are bundled, and
wherein the fiber bundle of the first fiber group are located between the fiber bundles of the second fiber group in the first direction when viewed from a front.

8. The hair attachment according to claim 1 ,
wherein the attachment part includes a plurality of linear bodies, and
wherein the attachment part is attached to the two fiber groups by direct sewing of the plurality of linear bodies onto the two fiber groups.

9. The hair attachment according to claim 1 ,
wherein the first linear part is sandwiched between the two fiber groups and is sewn onto the two fiber groups while meandering,
wherein the first linear part has an exposed part that is exposed to an outside from between the two fiber groups, and
wherein the exposed part of the first linear part is configured to form a plurality of annular parts together with the two fiber groups.

10. The hair attachment according to claim 9 ,
wherein the first linear part comprises:
an internal folded part that is folded inside the at least two fiber groups;
the forward connecting part directed from the internal folded part toward the external folded part; and
the return connecting part directed from the external folded part toward the internal folded part.

11. The hair attachment according to claim 10 , comprising a second linear part extending inside and outside the two fiber groups,
wherein the second linear part is partially disposed between the forward connecting part and the return connecting part outside the first linear part to be substantially flush with the forward connecting part and the return connecting part.

12. The hair attachment according to claim 9 , comprising a second linear part extending inside and outside the two fiber groups,
wherein the second linear part includes an exposed part that is exposed from the two fiber groups, the exposed part being outside the first linear part, the exposed part extending so as to surround the annular parts.

13. A hair attachment unit comprising:
a cap member that comprises a knitted part in which imitation hair is knitted, where the cap member is configured to cover a part or all of a head of a user;
the hair attachment according to claim 1 ; and
an attachment string for attaching the hair attachment to the cap member, wherein the attachment string passes through the annular parts and the knitted part, thereby attaching the annular parts to the knitted part, and
wherein the attachment string is untied when pulled in the first direction.

14. The hair attachment unit according to claim 13 , wherein the attachment string is stretchable in a longitudinal direction.

15. The hair attachment unit according to claim 14 , wherein the attachment string is stretchable up to 1.1 times or more with no load applied.
