Therefore, when wearing a wig, it must be fitted and aligned so that the leading edge of the wig fits in a position corresponding to the user's normal or general hairline. One problem with conventional wigs is that the boundary between the front edge of the worn wig and the user's forehead skin can be easily seen by a third party. And there are cases where things are revealed.

Patent Document 2 discloses a method for preventing the outer edge of the wig base from being exposed.
[0004] 一方、極薄人工皮膚に毛髪を植設したかつらを使用者の前額部のヘアライン対応 位置に接着剤で直接貼着し、頭部とかつらとの境目を自然に見せて生え際を視認し にくくする方法が特許文献 3に開示されている。 特許文献 4にも、極薄人工皮膚を生え際に使用し、頭部とかつらとの境目を自然に 見せて生え際部分を視認しに《する方法が開示されている。 [0004] On the other hand, a hair wig with ultra-thin artificial skin is directly attached to the hairline corresponding position on the user's forehead with an adhesive, and the hairline is shown by naturally showing the boundary between the head and the wig. Patent Document 3 discloses a method for making it difficult to visually recognize. Patent Document 4 also discloses a method of using an ultrathin artificial skin at the hairline to visually show the border between the head and the wig and visually recognize the hairline part.
特許文献 5には、波形を形成した針金状の枠線をかつらの前額部に取り付け、該 枠線にうぶ毛のような柔らか!/、毛髪を植設して生え際が自然に見えるようにする方法 が開示されている。  In Patent Document 5, a wire-like frame line having a corrugated shape is attached to the forehead part of the wig so that the hairline looks natural by planting the hair softly like vellus hair! Is disclosed.

Will be hit. As a result, the shape of the predetermined head shape collapses, and natural feeling cannot be brought about.
[0006] 特許文献 2のかつらにあっては、毛髪を植設した毛髪植設用ネット部分にめくれが 生じてしまうことがある。また、植毛用ネットとかつらベースの固定部分が厚くなつて、 かつらベース外縁部に自然感をもたせることができない。 [0006] In the wig of Patent Document 2, turning may occur at the hair-growing net portion where the hair is implanted. In addition, since the hair fixing net and the fixed part of the wig base are thick, it is not possible to give a natural feeling to the outer edge of the wig base.
V、ずれにしても特許文献 1及び特許文献 2の方法では、かつらベース自体の厚さは 変わらないので、かつらを装着したときに特に前額部の生え際の位置において、力 つらベースに相当な厚みが存在する。従って、前額部の皮膚との間で段差が生じて 、かつらベースの断面部分が視認され易 、傾向にある。  V, the thickness of the wig base itself does not change in the methods of Patent Document 1 and Patent Document 2 even if they are misaligned. There is a thickness. Therefore, there is a step between the forehead skin and the cross-sectional portion of the wig base tends to be visually recognized.
[0007] 特許文献 3では、極薄人工皮膚によって頭部全体を覆うような湾曲状のかつらを作 製しょうとしても、極薄人工皮膚が柔らかすぎるために頭部の湾曲状の型をつけるこ とができないため、装着者の頭部形状に合致するかつらを作製することができない。 特許文献 3に記載の、かつらベース裏面全面に接着層を設け、頭部に直接貼着する 方法では、貼着位置にずれが生じたり、しわが入ってしまうなど、うまく貼り付けること ができないことがあり、その場合、再び貼着し直すことができないといった欠点もあつ た。また、特許文献 3のかつらベースの接着層は、植設した毛髪の基端部をかつらべ ースに固定する第一接着層と、該第一接着層の上に頭部にかつらを貼着させるため の第二接着層とから成るが、この場合、接着層が二層から構成されることからかつら ベースが厚くなる欠点があった。 [0007] In Patent Document 3, even if an attempt is made to make a curved wig that covers the entire head with ultrathin artificial skin, the ultrathin artificial skin is too soft, and thus a curved head lip is attached. Therefore, a wig that matches the shape of the wearer's head cannot be produced. In the method described in Patent Document 3 where an adhesive layer is provided on the entire back surface of the wig base and directly attached to the head, the attachment position may be misaligned or wrinkled. However, there was a drawback that it could not be applied again. In addition, the wig-based adhesive layer of Patent Document 3 includes a first adhesive layer that fixes the proximal end portion of the planted hair to the wig base, and a wig attached to the head on the first adhesive layer. However, in this case, since the adhesive layer is composed of two layers, there is a disadvantage that the wig base becomes thick.
[0008] 特許文献 4の生え際の露見を防ぐ方法では、分髪部にのみ極薄人工皮膚が設けら れており、前額部の横方向のヘアラインには、頭部とかつらの見分けが付かないよう にするための工夫が施されて 、な 、。  [0008] In the method of preventing hairline exposure in Patent Document 4, an ultrathin artificial skin is provided only in the hair-splitting part, and the head and wig are distinguished from each other in the lateral hairline of the forehead part. A device has been devised to prevent it.
[0009] 特許文献 5のかつらでは、生え際における枠線の波形が、突出が大きい場合や先 端部の角度が鋭くなつている場合、頭部力 枠線が浮き上がる高さが想定よりも高く なり、枠線に毛髪を植設するとき枠線に毛髪を卷回して結ぶので、枠線がより露見し やすくなり、かつらの生え際が不自然になる可能性がある。また、枠線の露見を防ぐ ために、うぶ毛のような柔らかい毛髪を植設することが必須となっているが、該枠線に 植設するための毛髪を別に準備しなければならず、毛髪の準備に手間が力かり煩雑 となる。  [0009] In the wig of Patent Document 5, when the waveform of the frame line at the hairline is large and the angle of the tip end portion is sharp, the height at which the head force frame line floats is higher than expected. When hair is planted on the frame line, the hair is wound and tied to the frame line, so that the frame line is more easily exposed and the hairline of the wig may become unnatural. In addition, in order to prevent the exposure of the frame line, it is essential to plant soft hair such as vellus hair, but it is necessary to prepare a separate hair for the frame line, It takes time and effort to prepare hair.
[0010] 本発明は、このような事情を鑑みて創作されたものであり、かつらベースの前額部 の生え際に人工皮膚を設けることによって装着者のヘアラインとかつらとの見分けが 付かないようにし、且つ、装着者の頭部にフィットするかつらを提供することを第 1の 目的としている。本発明の第 2の目的は、上記かつらの製造方法を提供することにあ る。  [0010] The present invention was created in view of such circumstances, and by providing artificial skin on the hairline of the forehead portion of the wig base, it is possible to prevent the wearer from distinguishing between the hairline and the wig. The first object is to provide a wig that fits the wearer's head. A second object of the present invention is to provide a method for producing the wig.

発明の効果  The invention's effect
[0015] 本発明に係るかつら及びかつらの製造方法によれば、かつらベースのフロント部に おいて、装着者の前額部のヘアラインに相当する位置に前縁が位置する人工皮膚と 、このフロント部の後方に位置するリア部において、装着者の頭部に類似したネット型 に成形されたキャップ部材とを連接して組み合わせることで一枚のかつらベースとし ている。このため、かつらベースが装着者の頭部によくフィットし、し力も前額部の生え 際に迷彩効果が高い極薄人工皮膚を繰り返し貼り付け及び剥離することができるか つらを提供することがでさる。  According to the wig and the wig manufacturing method according to the present invention, the artificial skin having the front edge positioned at a position corresponding to the hairline of the forehead portion of the wearer on the front portion of the wig base, and the front In the rear part located behind the part, a cap member formed in a net shape similar to the head of the wearer is connected and combined to form a single wig base. For this reason, it is possible to provide a wig base that fits well to the wearer's head and can repeatedly apply and peel ultrathin artificial skin with a high camouflage effect on the forehead line. I'll do it.
[0016] かつら装着者の前額部の生え際に設ける極薄人工皮膚の表面側に艷消し処理を 施し、さらに極薄人工皮膚の前縁を波形状とすることにより、かつらの露顕が一層防 止されることができる。また、かつらベースに毛髪を植設した後、この人工皮膚の裏面 全面か又は少なくとも前縁を含む端部領域の一部に頭部に極薄人工皮膚部分を接 着させるための接着剤を塗布することによって、前額部の生え際において迷彩効果 をさらに高めることができるかつらを提供することができる。  [0016] The surface side of the ultrathin artificial skin provided at the hairline of the forehead portion of the wig wearer is subjected to a frosting process, and the front edge of the ultrathin artificial skin is wave-shaped to further prevent exposure of the wig. Can be stopped. In addition, after the hair is implanted in the wig base, an adhesive for attaching the ultrathin artificial skin part to the head is applied to the entire back surface of this artificial skin or at least a part of the end region including the front edge. By doing so, it is possible to provide a wig that can further enhance the camouflage effect at the hairline of the forehead.
[0017] 上記接着層は、一方側が人工皮膚の裏面に貫通して植設された毛髪の針足部を 固着する毛髪固定機能を付与されると共に、接着層の頭皮に貼着する側の面が頭 皮への再剥離機能を付与されて ヽる。接着剤が毛髪固定機能と頭皮への再剥離機 能を兼ね備えた一層のみの構成であるので、かつらの厚さを薄くでき軽量になる。 図面の簡単な説明  [0017] The adhesive layer is provided with a hair fixing function for fixing a needle foot portion of hair planted on one side through the back surface of the artificial skin, and is attached to the scalp of the adhesive layer. However, it is given a re-peeling function to the scalp. Since the adhesive has only a single layer structure that has both a hair fixing function and a re-peeling function to the scalp, the thickness of the wig can be reduced and the weight can be reduced.

[0020] 以下、図面を用いて本発明の実施形態を説明する。  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図 1 (A)及び図 1 (B)は本発明の実施形態に係るかつら 1を示す平面図であり、か つら 1のかつらベース la, lbは、かつら装着者の前額部に対応したフロント部とこの フロント部力 頭頂部及び後頭部へと続くリア部の 2つのパートで構成されており、フ ロント部には、極薄人工皮膚 10が配置され、リア部にはネット型 20が配置されていて 、これらは接合部 73で互いに結合されて一体ィ匕されて 、る。  1A and 1B are plan views showing a wig 1 according to an embodiment of the present invention. The wig base la, lb of the wig 1 is a front corresponding to the forehead portion of the wig wearer. This part consists of two parts, the front part and the rear part that leads to the top and back of the head.The ultrathin artificial skin 10 is placed in the front part, and the net 20 is placed in the rear part. These are joined together at the joint 73 and are integrated together.
図 1 (A)のかつらベース laは、毛髪植設の際、分け目を入れるヘアスタイルに適合 するように、使用者の前額部に対応する領域の他にさらに分髪部 Dに対応した位置 にも極薄人工皮膚 10が設けられている。一方、図 1 (B)のかつらベース lbは、ヘアス タイルを所謂オールバックにすることを想定し、使用者の前額部に対応する領域だけ に極薄人工皮膚 10を備えて ヽる。  The wig base la in Fig. 1 (A) is located at the position corresponding to the hair separation part D in addition to the area corresponding to the user's forehead part so as to be compatible with the hair style to be divided when hair is planted. In addition, an ultrathin artificial skin 10 is provided. On the other hand, the wig base lb shown in FIG. 1 (B) is provided with the ultrathin artificial skin 10 only in the region corresponding to the user's forehead, assuming that the hair style is a so-called all-back.
[0021] 本発明の実施形態に係る極薄人工皮膚 10は、かつら装着者の前額部に密着する ものであり、かつら装着者の前額部の形状に沿うように、例えば横方向に彎曲して形 成されている。また、ネット型 20も、かつら装着者の頭部の形状に沿うように凸状の湾 曲型が付けられて形成されている。人工皮膚 10の前縁は、かつら装着者の前額の 上部に本来存在するべきヘアラインに相当する位置に位置合わせされて密着される 。人工皮膚 10の裏面には全面に又は少なくとも前縁を含む端部領域の一部に、後 述するように、この人工皮膚 10には剥離不能に接着して毛髪の針足部を固定するが 、頭皮には繰り返して接着及び剥離し得るように加圧接着される接着層 30 (図 2参照 )が設けられている。リア部のネット型 20は例えばポリアミドやポリエステルなどの合成 榭脂の繊維で緻密な格子状に形成されるか、又は自毛を引き出せるよう大きな網目 に形成されていて、表面が浅い皿状に膨出したキャップ部材として構成される。フロ ント部とリア部とは、フロント部の人工皮膚 10の後縁とリア部のネット型 20の前縁とを ライン状に重ね合わさせて接着又は縫着した接合部 73により一体化され、全体とし て、装着者の頭部形状にできるだけ類似する型を有するように形成されている。 [0021] The ultrathin artificial skin 10 according to the embodiment of the present invention is in close contact with the forehead portion of the wig wearer, and is bent, for example, in the lateral direction so as to follow the shape of the forehead portion of the wig wearer. Is formed. The net type 20 is also formed with a convex curve shape along the shape of the head of the wig wearer. The front edge of the artificial skin 10 is aligned and brought into close contact with a position corresponding to the hairline that should originally exist on the upper part of the wig wearer's forehead. As will be described later, the artificial skin 10 is adhered to the artificial skin 10 on the entire back surface or at least a part of the end region including the front edge to fix the needle foot portion of the hair. The scalp is provided with an adhesive layer 30 (see FIG. 2) that is pressure-bonded so that it can be repeatedly bonded and peeled off. The rear net type 20 is a synthetic material such as polyamide or polyester. The cap member is formed in a fine lattice shape with a fiber of rosin, or is formed in a large mesh so that its own hair can be pulled out, and is configured as a cap member bulged into a shallow dish shape. The front part and the rear part are integrated by a joint part 73 in which the rear edge of the artificial skin 10 at the front part and the front edge of the net part 20 at the rear part are overlapped in a line shape and bonded or sewn together. Thus, it is formed so as to have a mold that is as similar as possible to the shape of the head of the wearer.
[0022] 図 2 (A)は、図 1 (B)のかつらベース lbの裏面を示す図であり、フロント部の極薄人 ェ皮膚 10の前縁に沿って、単一層でなるかつら用接着層(以下、適宜、接着層と呼 ぶ) 30が所定の幅でライン状に塗布されている。尤も、図 2 (B)に示すように、極薄人 工皮膚 10の前縁の輪郭に沿って、所定の間隔を置いて散点状に複数の接着層 30 を塗布してもよい。或いは、接着層 30は、極薄人工皮膚 10の裏面全体に塗布されて いてもよい。なお、図 1及び図 2において、かつらベース la, lbにはその表面側に多 数の毛髪が植設されているが、植設した毛髪の図示は省略している。  [0022] FIG. 2 (A) is a view showing the back surface of the wig base lb of FIG. 1 (B), and is a single layer adhesive for wigs along the front edge of the ultrathin human skin 10 in the front part. A layer (hereinafter referred to as an adhesive layer as appropriate) 30 is applied in a line with a predetermined width. However, as shown in FIG. 2B, a plurality of adhesive layers 30 may be applied in the form of dots at predetermined intervals along the contour of the front edge of the ultrathin artificial skin 10. Alternatively, the adhesive layer 30 may be applied to the entire back surface of the ultrathin artificial skin 10. In FIGS. 1 and 2, a large number of hairs are implanted on the surface side of the wig base la, lb, but illustration of the implanted hairs is omitted.
[0023] 図 3は、本発明の実施形態に係る極薄人工皮膚 10の構成を模式的に示す断面図 である。かつらベースのフロント部を構成する極薄人工皮膚 10は、かつら装着者の 前額部に本来存在するべきヘアラインに相当する位置に配置される前縁と頭部後方 に所定幅で広がったほぼ弧状の輪郭を呈しており、極薄人工皮膚材 11と、該極薄人 ェ皮膚材 11に植設される毛髪 12と、接着層 30とから構成されている。  FIG. 3 is a cross-sectional view schematically showing the configuration of the ultrathin artificial skin 10 according to the embodiment of the present invention. The ultra-thin artificial skin 10 that forms the front part of the wig base is a substantially arc-like shape that spreads with a predetermined width on the front edge and the back of the head, which is located at the position corresponding to the hairline that should be originally present on the forehead part of the wig wearer. It is composed of an ultrathin artificial skin material 11, hair 12 implanted in the ultrathin human skin material 11, and an adhesive layer 30.
[0024] 本発明の実施形態に係る極薄人工皮膚材 11は、例えばウレタン榭脂のような軟質 合成樹脂を用いて極薄に形成されており、例えば、厚さが 0. 08mn!〜 0. 12mmに 設定されている。図 1 (A)及び図 1 (B)のかつらベース la, lbにおいては、詳細は後 述する力 フロント部の前縁が波形状に形成されている。  [0024] The ultrathin artificial skin material 11 according to the embodiment of the present invention is formed extremely thin using, for example, a soft synthetic resin such as urethane resin, and has a thickness of 0.008mn! ~ 0.1 It is set to 12mm. In the wig bases la and lb in FIGS. 1 (A) and 1 (B), the front edge of the force front part, which will be described in detail later, is formed in a wave shape.
[0025] 極薄人工皮膚材 11へ植設される毛髪 12は、人毛又は人工毛からなる。図 3に示す ように、毛髪 12は極薄人工皮膚材 11の表面側から裏面に貫通して植設され、再び 極薄人工皮膚材 11の表面側に引き抜くことにより、 V字状又は U字状に植設されて いる。この極薄人工皮膚材 11の裏面に貫通し、裏面側に露出する毛髪部を針足部 1 2Aと呼ぶことにする。なお、このような植設方法を、通常、 V植えと称している。  [0025] The hair 12 implanted in the ultrathin artificial skin material 11 is composed of human hair or artificial hair. As shown in Fig. 3, the hair 12 is implanted through the surface of the ultrathin artificial skin material 11 from the front side to the back side, and is pulled out again to the front side of the ultrathin artificial skin material 11, thereby forming a V-shape or U-shape. It is planted in a shape. The hair portion that penetrates the back surface of the ultrathin artificial skin material 11 and is exposed on the back surface side is referred to as a needle foot portion 12A. This planting method is usually called V planting.
[0026] 次に、本発明の実施形態において、極薄人工皮膚材 11に塗布される接着層 30に ついて説明する。この接着層 30は単一層で成る。単一層で成るかつら用接着層 30 は、一面側が極薄人工皮膚 10の裏面には剥離不能に接着され、一方、他面側はか つら装着者の頭部に再剥離可能に加圧接着され得る特質を持った新規な構造を有 している。この接着層 30の一面側は極薄人工皮膚材 11の裏面に貫通して植設され る毛髪の針足部 12Aを固定する毛髪固定機能を有して剥離不能に人工皮膚材 11 接着されている。上記接着層 30は人工皮膚材 11の裏面全面に形成されてもよぐ或 いは、人工皮膚材 11の裏面にぉ 、て前縁を含む端部領域の一部分にライン状に又 は散点状に形成されてもょ ヽ。 Next, the adhesive layer 30 applied to the ultrathin artificial skin material 11 in the embodiment of the present invention will be described. This adhesive layer 30 consists of a single layer. Single layer wig adhesive layer 30 Has a new structure with the property that one side can be non-peeled to the back of the ultrathin artificial skin 10 while the other side can be pressure-bonded to the wearer's head so that it can be peeled again. Yes. One side of this adhesive layer 30 has a hair fixing function for fixing the needle foot 12A of the hair that is implanted through the back surface of the ultrathin artificial skin material 11, and is attached to the artificial skin material 11 so that it cannot be peeled off. Yes. The adhesive layer 30 may be formed on the entire back surface of the artificial skin material 11, or may be formed on the back surface of the artificial skin material 11 in a line or scattered manner on a part of the end region including the leading edge. It may be formed into a shape.
本発明に係るかつらベースのフロント部は、上記のように、極薄人工皮膚材 11と、 極薄人工皮膚材 11用の単一の層でなる接着層 30と、の 2層構造で構成されている。  As described above, the front part of the wig base according to the present invention has a two-layer structure of the ultrathin artificial skin material 11 and the adhesive layer 30 formed of a single layer for the ultrathin artificial skin material 11. ing.
[0027] 接着層 30についてさらに具体的に説明する。この接着層 30の一面側は、極薄人 ェ皮膚材 11裏面に塗布した接着剤溶液のゲルィ匕反応により、極薄人工皮膚材 11 裏面に化学的結合により接着している。従って、毛髪 12の針足部 12Aは、接着層 30 が極薄人工皮膚材 11へ接着されるときに極薄人工皮膚材 11と接着層 30との間に挟 まれて、同時に極薄人工皮膚材 11裏面に固定される。  [0027] The adhesive layer 30 will be described more specifically. One surface side of the adhesive layer 30 is adhered to the back surface of the ultrathin artificial skin material 11 by chemical bonding by the gelling reaction of the adhesive solution applied to the back surface of the ultrathin human skin material 11. Accordingly, the needle foot 12A of the hair 12 is sandwiched between the ultrathin artificial skin material 11 and the adhesive layer 30 when the adhesive layer 30 is bonded to the ultrathin artificial skin material 11, and at the same time, the ultrathin artificial skin. Material 11 Fixed to the back.
[0028] 一方、接着層 30の頭部に当接する面は、頭部へ繰り返し貼着及び剥離可能に、す なわち再剥離可能に加圧接着され得るようになつている。この接着層 30の頭部への 再剥離機能は、上記接着剤のゲル化反応後において発現される。このため、ゲルィ匕 反応終了後の接着層 30は頭部に対しては、常温で、短時間、わずかな力を加える だけで接着できる。即ち、加圧接着できる感圧型接着層 (所謂粘着層)の性質を有し ている。さらに、ゲルィ匕反応終了後の接着層 30は、微量の水や有機溶剤などでその 表面を拭うことにより、頭皮への繰り返し貼着ができる。この繰り返し貼着ができること を、本発明において再剥離機能或いは単に剥離機能と称している。なお、図 3に示 すように、接着層 30の頭皮への接着面には、装着者が手で容易に剥がすことができ る塩ィ匕ビュルシートなどの剥離シート 40を設けておけば好ましい。  On the other hand, the surface of the adhesive layer 30 that comes into contact with the head can be pressure-bonded to the head repeatedly so that it can be repeatedly attached and peeled, that is, re-detachable. This re-peeling function to the head of the adhesive layer 30 is manifested after the gelation reaction of the adhesive. For this reason, the adhesive layer 30 after completion of the Gelby reaction can be bonded to the head at room temperature by applying a slight force for a short time. That is, it has the property of a pressure-sensitive adhesive layer (so-called adhesive layer) that can be pressure-bonded. Further, the adhesive layer 30 after the gelling reaction can be repeatedly attached to the scalp by wiping the surface with a small amount of water or an organic solvent. The ability to repeatedly attach is referred to as a re-peeling function or simply a peeling function in the present invention. As shown in FIG. 3, it is preferable to provide a release sheet 40 such as a salty bull sheet that can be easily peeled off by the wearer on the adhesive surface of the adhesive layer 30 to the scalp. .
[0029] 次に、本発明のかつら用接着層 30の材料について説明する。  Next, the material for the wig adhesive layer 30 of the present invention will be described.
接着層 30の形成に用いられるかつら用接着剤としては、大別すると、ウレタン榭脂 系、アクリル榭脂系、ゴム系が挙げられる。  The wig adhesive used for forming the adhesive layer 30 can be broadly classified into urethane resin, acrylic resin, and rubber.
ウレタン榭脂系のかつら用接着剤は、後述するように、毛髪 12の針足部 12Aを極 薄人工皮膚材 11に固定する接着性が良好であり、且つ、接着層 30と極薄人工皮膚 材 11との間を剥離不能に強接着できる性質を有している。また頭部に貼着する場合 の再剥離性能が良好であり、低皮膚刺激性である。このため、ウレタン榭脂系のかつ ら用接着剤は、本発明の接着層 30を形成するかつら用接着剤として好適に使用す ることがでさる。 Urethane greaves-based wig adhesive is used to connect the needle foot 12A of hair 12 to the pole as described later. The adhesive property for fixing to the thin artificial skin material 11 is good, and the adhesive layer 30 and the ultrathin artificial skin material 11 can be strongly bonded together without being peeled. In addition, it has good re-peeling performance when applied to the head and is low skin irritation. For this reason, the urethane-resin-based wig adhesive can be suitably used as the wig adhesive for forming the adhesive layer 30 of the present invention.
[0030] 一方、アクリル榭脂系の接着剤は、粘着性は優れるが、再剥離性能が弱く皮膚刺 激性も強いことがある。ゴム系は、初期の粘着性は優れているが、時間の経過と共に 再剥離性能が著しく低下する問題がある。  [0030] On the other hand, an acrylic resin-based adhesive has excellent tackiness, but may have poor re-peeling performance and strong skin irritation. The rubber system is excellent in initial tackiness, but has a problem that the re-peeling performance is remarkably lowered with time.
[0031] さらに上記かつら用接着層 30をアクリル榭脂系及びゴム系の接着剤により形成す ると、榭脂自体の硬さから、頭皮に貼着したときに皮膚の動きに追従できず頭部との 密着性が低下して剥離しやすいこと、毛髪 12の針足部 12Aをかつらベース la, lb に固定する接着性が弱いこと、接着層 30とかつらベース la, lbとの間の接着性が弱 く剥離も容易に起こることから、使用に適さない。  [0031] Furthermore, when the wig adhesive layer 30 is formed of an acrylic resin-based or rubber-based adhesive, the hardness of the resin itself cannot follow the movement of the skin when attached to the scalp. Adhesion between the adhesive layer 30 and the wig base la, lb is weak. Adhesion between the adhesive layer 30 and the wig base la, lb is weak. It is not suitable for use because of its weak nature and easy peeling.
[0032] 次に、ウレタン榭脂系のかつら用接着剤を用いて接着層 30を形成する場合につい て、さらに詳しく説明する。  [0032] Next, the case where the adhesive layer 30 is formed using a urethane grease-based wig adhesive will be described in more detail.
ウレタン榭脂系のかつら用接着剤としては、主剤及び硬化剤からなる 2液混合型の 接着剤を好適に使用することができる。主剤はウレタン榭脂を主成分とするポリオ一 ル、硬化剤はポリイソシァネートを主成分とすることができる。これら 2液を混合してゲ ル化反応させ、ゲルィ匕反応終了後にゲルとなるものが好適である。このゲルィ匕はカロ 熱により促進できる。これにより、ゲルイ匕の過程において、硬化剤中に含まれているィ ソシァネートの作用により表面張力などの物理的な結合力だけでなく化学的な結合 力が加わる。このため、極薄人工皮膚材 11と接着層 30との間の接着力と、極薄人工 皮膚材 11とそれに植設した毛髪 12の針足部 12Aとの固着力が著しく向上して、従 来の接着剤による毛止め工程と同程度の固着力が得られる。なお、固着力とは、本 発明の接着層 30において、極薄人工皮膚材 11とそれに植設した毛髪 12の針足部 1 2Aへの接着力と定義し、通常の熱賦活型接着剤による接着力とは、区別するために 用いる。  As the urethane grease-based wig adhesive, a two-component mixed adhesive composed of a main agent and a curing agent can be suitably used. The main agent can be a polyol mainly composed of urethane resin, and the curing agent can be mainly composed of polyisocyanate. It is preferable that these two liquids are mixed and subjected to a gelation reaction to form a gel after completion of the gelling reaction. This gel can be promoted by calo heat. As a result, in the process of gelling, not only a physical bonding force such as surface tension but also a chemical bonding force is applied by the action of the isocyanate contained in the curing agent. For this reason, the adhesion force between the ultrathin artificial skin material 11 and the adhesive layer 30 and the adhesion force between the ultrathin artificial skin material 11 and the needle foot 12A of the hair 12 implanted therein are significantly improved. Adhesive strength comparable to that of a conventional adhesive-carrying process can be obtained. The adhesive strength is defined as the adhesive strength of the ultrathin artificial skin material 11 and the hair 12 implanted on the needle 12 to 12A in the adhesive layer 30 of the present invention, and is based on a normal heat-activated adhesive. Used to distinguish from adhesive strength.
[0033] さら〖こ、 2液混合型ウレタン榭脂系のかつら用接着剤は、反応後にゲル状構造の接 着層、即ち、粘着層となるので、前額部の極薄人工皮膚 10の装着時に頭部の動きに 追従するという優れた反応を示し、頭皮との密着性が低下せずに、十分なかつら粘 着力が発現する。 [0033] Sarakuko, a two-component mixed urethane-resin-based wig adhesive, has a gel-like structure after the reaction. Since it becomes an adhesive layer, that is, an adhesive layer, it exhibits an excellent reaction of following the movement of the head when wearing the ultrathin artificial skin 10 in the forehead, and the adhesion with the scalp is not lowered and sufficient Wig sticking power is developed.
[0034] 次に、植設した毛髪 12の針足部 12aの極薄人工皮膚材 11への固着力を付与する 方法について説明する。この方法は、 2液混合型ウレタン榭脂系のモノマーからなる 接着剤を混合し、この 2液中に艷消しかつらベース la, lbの材質の有機溶剤を少量 添加した接着剤を極薄人工皮膚材 11に塗布し、乾燥することにより実施できる。この ような有機溶剤としては、極薄人工皮膚材 11の材料がウレタンエラストマ一の場合に は、ジメチルホルムアミド(DMF)ゃメチルェチルケトン(MEK)などを使用できる。  [0034] Next, a method for imparting the adhesion force of the needle foot 12a of the implanted hair 12 to the ultrathin artificial skin material 11 will be described. This method involves mixing an adhesive consisting of a two-component mixed urethane-resin-based monomer, and adding a small amount of an organic solvent of the material of the wig base la and lb to this two-component ultrathin artificial skin. This can be done by applying to material 11 and drying. As such an organic solvent, when the material of the ultrathin artificial skin material 11 is urethane elastomer, dimethylformamide (DMF), methyl ethyl ketone (MEK), or the like can be used.
[0035] 接着層 30の毛髪 12の針足部 12Aの固着力及び頭部への粘着力の大きさは、 2液 混合型ウレタン榭脂系のかつら用接着剤の主剤及び硬化剤の混合割合の調整と、 塗工粘度の調整と、 2液混合した後に毛髪 12を植設した極薄人工皮膚材 11に塗布 するまでの静置時間の調整などにより、調節できる。  [0035] The adhesion strength of the hair 12 of the adhesive layer 30 and the needle foot portion 12A of the hair 12A and the adhesive strength to the head are determined by the mixing ratio of the main component and the curing agent of the two-component mixed urethane grease-based wig adhesive. It can be adjusted by adjusting the coating viscosity, adjusting the coating viscosity, and adjusting the standing time until the hair 12 is applied to the ultrathin artificial skin material 11 after mixing the two liquids.
[0036] 本発明の実施形態に係る極薄人工皮膚 10の変形例について図 4及び図 5を参照 して説明する。かつらベースのフロント部において、極薄人工皮膚 10Aは、艷消し極 薄人工皮膚材 15とその裏面に設けた単一の層でなる接着層 30との 2層構造でなり、 単一層でなる接着層 30が艷消し極薄人工皮膚材 15裏面の前縁所定幅または前縁 を含む端部領域の一部分に剥離不能に接着され、毛髪 12の針足部 12Aの固着機 能と頭部への再剥離機能とを有して 、る。  A modification of the ultrathin artificial skin 10 according to the embodiment of the present invention will be described with reference to FIG. 4 and FIG. At the front part of the wig base, the ultrathin artificial skin 10A has a two-layer structure consisting of a matte ultrathin artificial skin material 15 and a single layer adhesive layer 30 provided on the back surface of the wig base. Layer 30 is erased, ultrathin artificial skin 15 Adhered to a part of the end area including the predetermined width of the front edge or the front edge of the back surface in a non-peelable manner, the function of fixing the needle foot 12A of the hair 12 and the head It has a re-peeling function.
[0037] 図 4及び図 5に示すように、極薄人工皮膚 10Aが上記図 1、図 2に示す極薄人工皮 膚 10と異なるのは、極薄人工皮膚材 15の表面に、艷消しのための微細な凹凸部 15 Dが形成され、且つ、艷消し剤 16が添加されていることである。この微細な凹凸部 15 Dは、凹部 15Bと凸部 15Cとからなる。図示の場合、艷消し剤 16は表面側から所定 の領域 15Aまで添加されている力 艷消し剤 16はかつらベース中の任意の領域に 添加すればよい。他の構成は上述の極薄人工皮膚 10と同じである。  [0037] As shown in FIGS. 4 and 5, the ultrathin artificial skin 10A differs from the ultrathin artificial skin 10 shown in FIGS. 1 and 2 above on the surface of the ultrathin artificial skin material 15. That is, a fine uneven portion 15D is formed, and an erasing agent 16 is added. The fine uneven portion 15D is composed of a concave portion 15B and a convex portion 15C. In the case shown in the figure, the decoloring agent 16 added from the surface side to the predetermined region 15A may be added to any region in the wig base. Other configurations are the same as those of the ultrathin artificial skin 10 described above.
[0038] かつらベース la, lbを軽量ィ匕するために厚さを薄くする場合には、艷消し効果と頭 部に貼着したときの皮膚の動きへの追従性とを考慮して、艷消し剤 16を艷消し極薄 人工皮膚材 15の表面側にできるだけ浅く添加するのが好ましい。一例として、艷消し 極薄人工皮膚材 15の厚さを 0. 08mm〜0. 12mm程度にする場合には、艷消し剤 16を艷消し極薄人工皮膚材 15の表面側から 0. 03〜0. 035mm程度の深さまで添 加することが好ましい。 0. 03mmよりも浅いと艷消し効果が十分でなぐ 0. 035mm よりも厚いと艷消しされた極薄人工皮膚材 15が硬化し、頭皮の動きに追従し難くなり 好ましくない。 [0038] When reducing the thickness of the wig base la and lb in order to reduce the weight, it is necessary to consider the erasing effect and the ability to follow the movement of the skin when applied to the head. It is preferable to add the decontaminant 16 to the surface side of the artificial skin material 15 as shallow as possible. As an example, erasure When the thickness of the ultrathin artificial skin material 15 is about 0.08 mm to 0.12 mm, the matting agent 16 is erased and the thickness of the ultrathin artificial skin material 15 is about 0.03 to 0.035 mm. It is preferable to add to the depth. If the thickness is less than 03 mm, the erasing effect is not sufficient. If it is thicker than 0.35 mm, the erased ultrathin artificial skin material 15 is hardened and it is difficult to follow the movement of the scalp.
[0039] 艷消し剤 16は各種の無機物粒子が使用できる。この無機物粒子の材料としては、 シリカ、酸化チタン、酸ィ匕アルミニウム、水酸ィ匕アルミニウム、炭酸マグネシウム、炭酸 カルシウム、ゼォライト、硝子の何れかを用いることができる。特に、粒子径が 1〜10 mの粉末状のシリカが好適である。粉末状のシリカは、塗布する適宜な有機溶剤 中に溶解させた熱可塑性エラストマ一重量に対して 5〜25%が望ましい。艷消し剤 1 6として例えば粉末状のシリカを用いれば、被着者の頭皮の色が透けて見えるので、 艷消し極薄人工皮膚材 15と頭部の境目が視認され難くなり、かつら装着時の自然さ が向上する。  [0039] As the matting agent 16, various inorganic particles can be used. As the material of the inorganic particles, any one of silica, titanium oxide, aluminum oxide, aluminum hydroxide, magnesium carbonate, calcium carbonate, zeolite, and glass can be used. In particular, powdered silica having a particle size of 1 to 10 m is suitable. The powdered silica is desirably 5 to 25% based on one weight of the thermoplastic elastomer dissolved in an appropriate organic solvent to be applied. If, for example, powdered silica is used as the erasing agent 16, the color of the scalp of the wearer can be seen through, so it becomes difficult to see the boundary between the erasing ultrathin artificial skin material 15 and the head, The naturalness of the is improved.
[0040] 微細な凹凸部 15Dは、後述するように、ネット状の織物などの細メッシュを用いた転 写により形成することができる。この転写により、艷消し極薄人工皮膚材 15には微細 な凹凸が形成される。この凹凸が皮膚を擬似した模様を呈する。  [0040] As will be described later, the fine uneven portion 15D can be formed by transfer using a fine mesh such as a net-like woven fabric. By this transfer, fine irregularities are formed on the erased ultrathin artificial skin material 15. This unevenness simulates the skin.
[0041] 艷消し極薄人工皮膚材 15の厚さは 0. 08〜0. 12mm程度が好ましい。艷消し極 薄人工皮膚材 15の厚さが 0. 08mmよりも薄い場合は、艷消し極薄人工皮膚材 15の 形態安定性が弱くなつてしまうため、装着中の艷消し極薄人工皮膚材 15が装着者の 頭部形状に合わなくなってしまう。また艷消し極薄人工皮膚材 15の厚さが 0. 12mm よりも厚 、場合は、かつら装着時に頭皮とかつらベースの境目の位置に段差が生じ、 厚みによってかつらベースの断面が目立ち、かつら装着が視認され易ぐさらに装着 時に頭皮の動きにかつらベースが追随できなくなってしまう。  [0041] The thickness of the ultrathin artificial skin material 15 is preferably about 0.08 to 0.12 mm. If the thickness of the erased ultrathin artificial skin material 15 is less than 0.08 mm, the morphological stability of the erased ultrathin artificial skin material 15 will be weakened. 15 will not fit the wearer's head shape. In addition, if the thickness of the erased ultrathin artificial skin material 15 is thicker than 0.12 mm, a step will occur at the boundary between the scalp and the wig base when wearing the wig, and the cross section of the wig base will be conspicuous depending on the thickness. The wig base will not be able to follow the movement of the scalp when it is easily worn.
[0042] 本発明の艷消し極薄人工皮膚材 15によれば、艷消し剤 16及び微細な凹凸部 15 Dによる乱反射により、複合された艷消し効果が発揮される。そして、粉末状のシリカ は透明であり、装着者の頭部の色が透けて見えるので、前額部の極薄人工皮膚 10 Aと頭部の境目が視認され難くなり、かつら装着時の自然さが向上する。  [0042] According to the erasing ultrathin artificial skin material 15 of the present invention, a combined erasing effect is exhibited by the irregular reflection by the erasing agent 16 and the fine irregularities 15D. The powdered silica is transparent and the color of the wearer's head can be seen through, making it difficult to see the border between the ultrathin artificial skin 10 A on the forehead and the head, and when wearing the wig. Will improve.
[0043] 無機物の添加のみでは艷消し極薄人工皮膚材 15が硬くなつたり、所望の光沢が得 られても、添加した無機物の作用により、艷消しされたかつらベース la, lbの色合い が大きく変化して、装着者の頭部の色に近似させることが困難であった力 本発明の 構造にすることによってこのような欠点が解決される。 [0043] With only the addition of an inorganic substance, the frosted ultrathin artificial skin material 15 becomes hard or a desired gloss is obtained. Even if it is applied to the structure of the present invention, it is difficult to approximate the color of the wearer's head because the color of the erased wig base la, lb is greatly changed by the action of the added inorganic substance. By doing so, such a drawback is solved.
[0044] 上記変形例によれば、頭皮の動きに追従し易ぐ且つ、艷消し効果の極めて高い 艷消し極薄人工皮膚材 15を用いることにより、再剥離性を有する前額部の艷消し極 薄人工皮膚 10Aを実現できる。 [0044] According to the above-described modification, the forehead portion having removability is erased by using the ultrathin artificial skin material 15 that easily follows the movement of the scalp and has a very high decoloring effect. Ultra-thin artificial skin 10A can be realized.
[0045] 次に、かつら前額部の前縁に形成する波形形状について説明する。 Next, the waveform shape formed on the front edge of the wig front forehead will be described.
フロント部に設けた艷消し極薄人工皮膚材 15について、さらに迷彩効果を高める ため、フロント部の前縁の少なくとも一部分に、図 1 (A)及び図 1 (B)に示すように、波 形状の切り込みを入れる。  In order to further enhance the camouflage effect, the corrugated ultrathin artificial skin material 15 provided on the front part has a wave shape on at least a part of the front edge of the front part as shown in FIGS. 1 (A) and 1 (B). Make a notch.
この前縁の波形形状は、艷消し極薄人工皮膚材 15を切除することにより形成され る。切除の際に、艷消し極薄人工皮膚材 15の前縁の加工を行う。図 6は、本発明の 実施形態に係る艷消し極薄人工皮膚材 15の前縁に実施する形状加工の模式図で ある。図中の波形形状について、長手方向に対して凸型部分の頂上を頂点 51、両 側の山の間にある谷の底部分を谷間 52と表記する。  The corrugated shape of the leading edge is formed by excising the erased ultrathin artificial skin material 15. At the time of excision, the leading edge of the erased ultrathin artificial skin material 15 is processed. FIG. 6 is a schematic diagram of the shape processing performed on the front edge of the erased ultrathin artificial skin material 15 according to the embodiment of the present invention. Regarding the corrugated shape in the figure, the top of the convex part with respect to the longitudinal direction is expressed as apex 51, and the bottom of the valley between the peaks on both sides is expressed as valley 52.
[0046] ここで、図 7〜図 12は図 6で示した波形形状との比較を行うための模式図である。ま ず、切り込みを波形とする理由は、フロント部前縁の形状を図 7,図 8のような三角形 や四角形等の多角型にすると、頭部にかつらを装着した場合に艷消し極薄人工皮 膚材 15の前縁の突出部分 53がめくれて、かつらの露見につながる可能性がある。こ のため、切り込みの形状は先端部に丸みを帯びている波形が適している。 Here, FIGS. 7 to 12 are schematic diagrams for comparison with the waveform shape shown in FIG. First, the reason why the notch is corrugated is that if the front edge of the front is a polygon such as a triangle or quadrangle as shown in Figs. The protruding part 53 of the leading edge of the skin material 15 may turn over, leading to exposure of the wig. For this reason, a corrugated shape with a rounded tip is suitable.
[0047] 波形形状の寸法は、図 6における頂点 51から谷間 52までの長手方向に対する垂 直方向の長さ、即ち、深さ Aが 1. Omm〜3. Ommとすることが好ましい。深さ Aが図 9に示すように 3. Ommよりも大きいと、かつら装着の際に頂点 51を含んだ突片にめ くれが生じて露見につながる可能性がある。深さ Aが図 10に示すように 1. Ommより も小さいと、前縁を直線状に処理したものと比べて波形の前縁との差がほとんど無ぐ 十分な迷彩効果を持たせることができな 、。  [0047] The dimension of the corrugated shape is preferably such that the length in the vertical direction with respect to the longitudinal direction from the vertex 51 to the valley 52 in FIG. 6, that is, the depth A is 1. Omm to 3. Omm. If depth A is greater than 3. Omm, as shown in Fig. 9, when the wig is attached, the protrusion including the apex 51 may be turned over, leading to exposure. As shown in Fig. 10, when depth A is smaller than Omm, there is almost no difference from the leading edge of the waveform compared to the straight edge processed, so that a sufficient camouflage effect can be achieved. Can not ,.
[0048] 図 6における頂点 51aからそれに隣接する頂点 51bまでの長手方向の長さ Bは 7. 0 mm〜30. Ommに設定するのが望ましい。長手方向の波形の長さ Bが 30. Ommより も大きいと、図 11に示すように、波形状の切り込みを入れずに直線状として処理した ものと変わりが無ぐ迷彩効果を持たせることができない。長手方向の波形の長さ Bが 7. Ommよりも小さいと、前縁の形状は図 12に示すように鋸刃状になって頂点 51を 含む山型部分が突出する形状となるため、装着時にめくれが生じる可能性がある。 [0048] The length B in the longitudinal direction from the vertex 51a to the vertex 51b adjacent to the vertex 51a in Fig. 6 is preferably set to 7.0 mm to 30. Omm. Longitudinal corrugation length B is 30. Omm If it is too large, as shown in Fig. 11, a camouflage effect that is the same as that processed as a straight line without cutting a wave shape cannot be provided. If the length B of the corrugation in the longitudinal direction is less than 7. Omm, the shape of the leading edge becomes a saw blade as shown in Fig. 12, and the chevron including the apex 51 protrudes. Sometimes turning over can occur.
[0049] ここで、人工皮膚の前縁に形成する波形の形状は全て同一でなくてもよぐ特定の 部分において深さやピッチが異なっていてもよい。例えば、図 13はフロント部の境界 線 C1から C2までの範囲において頂点 5 laからそれに隣接する頂点 5 lbまでの長手 方向の長さ B1と、該範囲以外の艷消し極薄人工皮膚材 15の頂点 51 から頂点 5 lb' までの長手方向の長さ B2とを、異なる長さとしたものである。フロント部の前縁 に設ける切り込みの寸法が上記の範囲内であると、フロント部の前縁の所定の位置 にて異なる形状の波形を形成することができる。  [0049] Here, the shape of the waveform formed on the leading edge of the artificial skin may not be the same, and the depth and pitch may be different in a specific portion. For example, FIG. 13 shows the length B1 in the longitudinal direction from the vertex 5 la to the adjacent vertex 5 lb in the range from the boundary C1 to C2 of the front part, and the erased ultrathin artificial skin material 15 outside the range. The longitudinal length B2 from the vertex 51 to the vertex 5 lb 'is a different length. When the size of the notch provided on the front edge of the front portion is within the above range, a waveform having a different shape can be formed at a predetermined position on the front edge of the front portion.
[0050] 波形状の切り込みを入れる部分は、実施例ではフロント部の生え際に設けた極薄 人工皮膚材 11, 15の前縁に形成している力 側部や後頭部等のフロント部以外の 外縁部にも切り込みを入れて迷彩効果を持たせることが可能である。例えば、図 14 に示すかつらベースのネット 20にお 、て、サイド部や後頭部側に波形を形成した場 合にも同様の迷彩効果を持たせることができる。  [0050] In the embodiment, the portion into which the wave-shaped cut is made is an outer edge other than the front part such as the side part and the occipital part of the ultrathin artificial skin material 11, 15 provided at the hairline of the front part. It is possible to give a camouflage effect by cutting the part. For example, the wig-based net 20 shown in FIG. 14 can have the same camouflage effect even when a waveform is formed on the side portion or the back of the head.
[0051] 次に、本発明の実施形態に係るかつらの製造方法について説明する。  [0051] Next, a method for manufacturing a wig according to an embodiment of the present invention will be described.
最初に、極薄人工皮膚材 11の製造方法について説明する。  First, a method for manufacturing the ultrathin artificial skin material 11 will be described.
第 1工程として、予め用意したかつら装着者の頭部形状の雄型 (例えば、石膏型等 )又は予め作られた典型的な頭部形状の幾つかのパターンの中から使用者の頭部 形状に最も類似する雄型を用いて、この雄型に、軟質合成樹脂からなるペレット状の 熱可塑性エラストマ一を有機溶剤に溶解した溶液 (以下、熱可塑性エラストマ一溶液 と呼ぶ)を塗布する。そして、雄型を乾燥して成形することで恰も頭部に近似した極薄 人工皮膚材 11が得られる。熱可塑性エラストマ一は各種適用可能であるが、例えば 、ウレタンエラストマ一が好ましい。必要に応じて防黴剤などを添加してもよい。このよ うにして極薄人工皮膚材 11を製造することができる。  As the first step, the shape of the user's head can be selected from a pre-prepared male shape of the head shape of the wearer (for example, a plaster mold or the like) or several typical patterns of a typical head shape. Using a male mold most similar to the above, a solution in which a pellet-shaped thermoplastic elastomer made of a soft synthetic resin is dissolved in an organic solvent (hereinafter referred to as a thermoplastic elastomer solution) is applied to the male mold. Then, by drying and molding the male mold, an ultrathin artificial skin material 11 that approximates the head of the heel is obtained. Various thermoplastic elastomers can be used. For example, urethane elastomers are preferable. You may add an antifungal agent etc. as needed. In this way, the ultrathin artificial skin material 11 can be manufactured.
[0052] 次に、極薄人工皮膚材 11に施す艷消し処理について説明する。  Next, the erasing process performed on the ultrathin artificial skin material 11 will be described.
第 2工程として、第 1工程で成形した極薄人工皮膚材 11に以下の工程により艷消し を行い、かつら表面に自然な艷消し光沢を付与する。 As the second step, the ultrathin artificial skin material 11 formed in the first step is erased by the following steps: To give the wig surface a natural matte luster.
具体的には、極薄人工皮膚材 11の作製で使用した熱可塑性エラストマ一溶液に 艷消し剤 16となる無機物粒子を添加した溶液を用意する。この溶液を極薄人工皮膚 材 11の表面に塗布して乾燥させる。極薄人工皮膚材 11の厚さが 0. 08-0. 12mm 程度の場合には、この溶液を塗布及び乾燥させたときの艷消し剤 16を含む領域 15 Aの深さを、 0. 03-0. 035mm程度にするのが好ましい。そのためには、塗布する 熱可塑性エラストマ一の粘度を調整すればよい。無機物粒子は各種適用可能である 力 粒子径 1〜: L0 mの粉末状のシリカが好ましぐその添加量は、塗布する溶液中 に溶解させた熱可塑性エラストマ一重量に対して 5〜25%が望ましい。必要に応じて 、艷消し剤 16と共に、紫外線吸収剤や黄変防止のための酸化剤などを添加してもよ い。  Specifically, a solution is prepared by adding inorganic particles to be the anti-fogging agent 16 to the thermoplastic elastomer solution used in the production of the ultrathin artificial skin material 11. This solution is applied to the surface of the ultrathin artificial skin material 11 and dried. When the thickness of the ultrathin artificial skin material 11 is about 0.08-0.12 mm, the depth of the region 15 A containing the defrosting agent 16 when this solution is applied and dried is set to 0.03. It is preferable to be about -0.035 mm. For this purpose, the viscosity of the thermoplastic elastomer to be applied may be adjusted. Various types of inorganic particles can be used. Force Particle size 1 to: L0 m powdered silica is preferred. The amount added is 5 to 25% of the weight of thermoplastic elastomer dissolved in the coating solution. Is desirable. If necessary, an ultraviolet absorber or an oxidizing agent for preventing yellowing may be added together with the anti-fogging agent 16.
[0053] 第 3工程として、第 2工程で表面上に艷消し剤 16が添加された極薄人工皮膚材 11 に細メッシュ状のネットを被せて、極薄人工皮膚材質の溶媒を塗布し、乾燥した後に 細メッシュ状のネットを取り除き、極薄人工皮膚材 11表面に細メッシュにより微細な凹 凸部 15Dを形成する。この工程で使用される細メッシュ状ネットは、上記極薄人工皮 膚材 11に塗布する溶媒に溶解しな 、材料であれば何れでもよ ヽ。例えばかつらべ ース la, lbをウレタン榭脂で形成した場合には、ナイロンを用いることができる。また 、細メッシュ状のネットは、 0. 03〜0. 1mmの糸径で編まれ、 30〜: L00メッシュ(本 Z インチ)程度のサイズが好ま 、。  [0053] As the third step, a thin mesh-like net is placed on the ultrathin artificial skin material 11 to which the decoloring agent 16 is added on the surface in the second step, and a solvent of the ultrathin artificial skin material is applied. After drying, the fine mesh-shaped net is removed, and fine concave and convex portions 15D are formed on the surface of the ultrathin artificial skin material 11 by the fine mesh. The fine mesh net used in this step may be any material as long as it does not dissolve in the solvent applied to the ultrathin artificial skin material 11. For example, when the wig base la, lb is formed of urethane resin, nylon can be used. In addition, the fine mesh net is knitted with a thread diameter of 0.03 to 0.1mm, 30 ~: L00 mesh (Z inch) is preferred.
上記第 2及び第 3工程により、第 1工程で成形した極薄人工皮膚材 11に艷消し処 理を施し、自然な艷消し光沢が付与された艷消し極薄人工皮膚材 15 (図 4参照)を 形成することができる。これにより、艷消し極薄人工皮膚材 15には、無機物粒子を添 カロした艷消し剤添加領域 15A及び微細な凹凸部 15Dの形成による複合された艷消 し処理が施される。  By the second and third steps, the ultrathin artificial skin material 11 molded in the first step is subjected to a erasing process, and a natural frosted gloss is applied to the erased ultrathin artificial skin material 15 (see Fig. 4). ) Can be formed. As a result, the erasing ultrathin artificial skin material 15 is subjected to a combined erasing process by forming the erasing agent-added region 15A with the inorganic particles added thereto and the fine uneven portions 15D.
[0054] 第 4工程として、合成樹脂製のネットを用意し、このネットに装着者の頭部の形状に 合わせた型を付けてネット型 20を得る。詳細は後述するが、合成樹脂製の扁平なネ ット 20に対して、装着者の頭部形状に合わせた型を用いて樹脂加工により成形する なお、ネット型 20の成形工程を第 1工程とし、第 2工程以下で人工皮膚材を成形す る作業を行なってもよ 、ことは勿論である。 [0054] As a fourth step, a net made of synthetic resin is prepared, and a net according to the shape of the wearer's head is attached to the net to obtain a net 20. Although details will be described later, the flat net 20 made of synthetic resin is molded by resin processing using a mold that matches the shape of the wearer's head. Needless to say, the molding process of the net mold 20 may be the first process, and the artificial skin material may be molded in the second and subsequent processes.
[0055] 第 5工程として、作製した艷消し極薄人工皮膚材 15の上に、予め装着者の頭部形 状に合わせたネット型 20を重ね合わせ、所定位置に所定幅で縫着又は接着して極 薄人工皮膚材 15とネット型 20とを接合部 73にて連接して一体ィ匕し、かつらベース la 、 lbを作製する。作製したかつらベースの形状とサイズは、全体として、装着者の頭 部形状にできるだけ類似するように形成されるとフィット感に優れて好まし 、。  [0055] As a fifth step, a net mold 20 that is preliminarily matched with the wearer's head shape is overlaid on the prepared erased ultrathin artificial skin material 15, and is sewn or bonded at a predetermined position with a predetermined width. Then, the ultrathin artificial skin material 15 and the net mold 20 are joined together at the joint 73 to form a wig base la and lb. The shape and size of the wig base produced as a whole is preferred because it has a good fit when formed so as to be as similar as possible to the wearer's head shape.
第 6工程として、艷消し極薄人工皮膚材 15と合成樹脂製のネット型 20に毛髪 12と なる人毛または人工毛を、それぞれ所定の方法により植設する。  As a sixth step, human hair or artificial hair to be the hair 12 is implanted in a predetermined method on the erased ultrathin artificial skin material 15 and the synthetic resin net mold 20.
[0056] 第 7工程では、毛髪 12を植設した艷消し極薄人工皮膚材 15の裏面に接着層 30を 形成する。接着層 30は、艷消し極薄人工皮膚材 15の裏面にある毛髪 12の針足部 1 2Aを艷消し極薄人工皮膚材 15に固定する機能と、頭部に貼着する機能を兼ね備え た接着剤を塗布し、乾燥させること〖こより形成することができる。この接着剤の塗布方 法としては、スプレー法や刷毛を用いた方法が使用できる。  [0056] In the seventh step, the adhesive layer 30 is formed on the back surface of the erased ultrathin artificial skin material 15 in which the hair 12 is implanted. The adhesive layer 30 has the function of erasing and fixing the needle feet 1 2A of the hair 12 on the back of the erased ultrathin artificial skin material 15 to the ultrathin artificial skin material 15 and the function of sticking it to the head. It can be formed by applying an adhesive and drying it. As a method for applying the adhesive, a spray method or a method using a brush can be used.
[0057] ここで、かつら用接着層 30の具体的な形成工程について説明する。  Here, a specific process for forming the wig adhesive layer 30 will be described.
最初に、毛髪 12を植設したかつらベース la又は lbを裏返してかつら装着者の頭 部形状雄型に固定する。この頭部形状雄型は、例えば、熱硬化性のエポキシ榭脂か ら形成される。次に、かつら用接着剤モノマーと有機溶剤を混合攪拌する。このかつ ら用接着剤モノマーとしては、イソシァネートを主成分とした物とポリオールを主成分 とした物の 2種類を用いることができる。必要に応じて、艷消し極薄人工皮膚材 15の 溶剤を加えても良い。  First, the wig base la or lb with the hair 12 implanted is turned over and fixed to the head shape male mold of the wig wearer. The male head-shaped mold is formed from, for example, a thermosetting epoxy resin. Next, the wig adhesive monomer and the organic solvent are mixed and stirred. Two types of adhesive monomers for wigs can be used: those based on isocyanate and those based on polyol. If necessary, a solvent for the erasing ultrathin artificial skin material 15 may be added.
[0058] この溶液を常温で所定時間静置して反応を進めて、かつら用接着剤溶液とする。こ こで、所定時間静置は、混合攪拌した上記溶液中の分子同士の架橋反応をある程 度進ませるために行う。次に、上記の所定時間静置した接着剤溶液を、艷消し極薄 人工皮膚材 15の裏面にハケで所望の厚みになるよう塗布し、常温以上の加熱温度 で所定時間乾燥させ、乾燥後、室温まで冷却することにより、接着層 30を形成するこ とができる。所望の厚さの接着層 30を得るために、上記接着剤溶液の塗布及び加熱 による乾燥を繰り返してもよ 、。 [0059] なお、艷消し極薄人工皮膚材 15と接着層 30との間の接着力と、艷消し極薄人工皮 膚材 15とそれに植設した毛髪 12の針足部 12Aとの間の接着力は、常温以上の加熱 速度で所定時間乾燥させるゲルイ匕の過程において発現する。 [0058] This solution is allowed to stand at room temperature for a predetermined time to proceed with the reaction to obtain a wig adhesive solution. Here, the standing for a predetermined time is performed in order to advance the crosslinking reaction between the molecules in the mixed and stirred solution to some extent. Next, the adhesive solution that has been allowed to stand for a predetermined time described above is applied to the back surface of the ultrathin artificial skin material 15 to a desired thickness by brushing, dried at a heating temperature of room temperature or higher for a predetermined time, and after drying The adhesive layer 30 can be formed by cooling to room temperature. In order to obtain an adhesive layer 30 having a desired thickness, application of the adhesive solution and drying by heating may be repeated. [0059] It is to be noted that the adhesive force between the erased ultrathin artificial skin material 15 and the adhesive layer 30 and between the erased ultrathin artificial skin material 15 and the needle foot portion 12A of the hair 12 implanted therein Adhesive strength develops in the process of gelling that is dried for a predetermined time at a heating rate of room temperature or higher.
[0060] 上記第 7工程により、本発明のかつら用接着層 30を形成し、フロント部の極薄人工 皮膚 15を作製することができる。さらに、かつら用接着層 30には、かつらを装着する 前の保護のために剥離用シート 40を設けてもよい。  [0060] Through the seventh step, the wig adhesive layer 30 of the present invention can be formed, and the ultrathin artificial skin 15 of the front portion can be produced. Further, a release sheet 40 may be provided on the wig adhesive layer 30 for protection before the wig is attached.
[0061] 第 8工程として、極薄人工皮膚材 15とネット 20の不要なはみ出し部分を切除する。  As an eighth step, unnecessary protruding portions of the ultrathin artificial skin material 15 and the net 20 are excised.
この切除の際に、艷消し極薄人工皮膚材 15の前縁の波形形状加工を行う。上記ェ 程を経てかつら 1が完成する。  At the time of this resection, the corrugated shape processing of the leading edge of the erased ultrathin artificial skin material 15 is performed. Wig 1 is completed through the above process.
ここで、上記かつらベースに対して毛髪を植設する第 6工程、人工皮膚の裏面に接 着層 30を形成する第 7工程、並びに人工皮膚及びネット型の不要なはみ出し部分を 切除する第 8工程は、この順序で作業を遂行する必要はなぐ何れの工程を先行し て行なってもよいことは明らかである。例えば、第 8の切除工程を第 5の接合部形成 工程の次に行なってもよい。或いは、植毛工程又は接着層形成工程を最後に行なう ことちでさる。  Here, the sixth step of implanting hair on the wig base, the seventh step of forming the adhesive layer 30 on the back surface of the artificial skin, and the eighth step of cutting off unnecessary protruding portions of the artificial skin and the net type Obviously, the process may be preceded by any process that does not need to be performed in this order. For example, the eighth excision step may be performed after the fifth joint formation step. Or, it can be done by performing the flocking process or the adhesive layer forming process last.
[0062] 本発明の実施形態に係るかつら 1は、単一層でなる接着層 30を使用することを特 徴としている。このため、従来の 2層構造の接着層をもったかつらにおける毛髪の針 足部の固着機能を有する第 1の接着層と、頭部への貼着機能を有する第 2の接着層 の機能を、単一層でなる接着層 30により実現することができる。これにより、フロント部 力 極薄人工皮膚材 11, 15及び単一層でなる接着層 30の簡単な構造で構成できる  [0062] The wig 1 according to the embodiment of the present invention is characterized by using a single-layer adhesive layer 30. For this reason, the functions of the first adhesive layer having the function of fixing the needle foot of the hair in the wig having the conventional two-layered adhesive layer and the function of the second adhesive layer having the function of sticking to the head are provided. It can be realized by an adhesive layer 30 composed of a single layer. As a result, the front part can be configured with a simple structure of the ultrathin artificial skin material 11, 15 and the single adhesive layer 30.
[0063] 単一層でなる接着層 30の厚さは、毛髪 12の針足部 12Aを固着できる程度でよぐ 例えば植設する毛髪 12の太さが 0. 08〜0. 09mmであれば 0. 05mm程度で済む ので、フロント部を軽量ィ匕することができる。 [0063] The thickness of the adhesive layer 30 made of a single layer is sufficient so that the needle foot portion 12A of the hair 12 can be fixed. For example, if the thickness of the hair 12 to be implanted is 0.08 to 0.09 mm, it is 0. Since only about 05 mm is required, the front part can be made lighter.
[0064] 頭部側に貼着する側の接着層 30は再剥離性を有し、接着層 30を水や有機溶剤で 洗うだけで粘着力が回復して繰り返し使用ができる。このため、低コストなかつら 1を 実現することができる。 [0064] The adhesive layer 30 on the side to be attached to the head side has removability, and the adhesive strength is recovered simply by washing the adhesive layer 30 with water or an organic solvent, so that it can be used repeatedly. For this reason, a low-cost wig 1 can be realized.

Drying was performed. Furthermore, a urethane elastomer solution having a lower concentration than that of the urethane elastomer solution is applied on the gypsum mold and dried at a heating temperature of 60 ° C. for 30 minutes, so that the thickness is about 0.07 mm. Artificial skin material 11 was produced.
[0066] 第 2工程として、ウレタンエラストマ一を DMF及び MEKに溶解させ、防黴剤を添カロ した溶液に、さらに、艷消し剤 6となる粉状シリカ(平均粒径 3. 1 μ m〜4. : L m)と、 紫外線吸収剤と、酸ィ匕防止剤とを添加して、艷消し用溶液を作製した。シリカの重量 は、ウレタンエラストマ一重量に対して、約 8%であった。この艷消し用溶液を極薄人 ェ皮膚材 11に塗布し、加熱温度 60°Cで、 2〜4時間程度乾燥させた。  [0066] In the second step, urethane elastomer is dissolved in DMF and MEK, and a solution obtained by adding an antifungal agent to powdered silica (average particle size 3.1 μm to 4 .: L m), an ultraviolet absorber, and an acid-proofing agent were added to prepare an erasing solution. The weight of silica was about 8% with respect to 1 weight of urethane elastomer. This erasing solution was applied to an ultrathin skin material 11 and dried at a heating temperature of 60 ° C. for about 2 to 4 hours.

Then, a mixture of MEK and DMF, which are solvents of the ultrathin artificial skin material 11, in a predetermined ratio was applied and dried at 100 ° C. for 4 hours. After drying, the stocking net was removed, and fine irregularities 21D were formed on the surface of the ultrathin artificial skin material 11. The diameter of the net for stockings was 0.05 mm, and the mesh was about 50 mesh (Z inch).
[0068] このようにして、ウレタン榭脂からなる極薄人工皮膚材 11の表面に、艷消し剤 16を 含む領域 15Aと凹凸部 15Dとを形成し、艷消し極薄人工皮膚材 15を製造した。艷 消し極薄人工皮膚材 15の厚さは、艷消し剤 16を含む領域 15Aにおいて 0. 03-0. 035mm程度増加して、全体の艷消し極薄人工皮膚材 15の厚みが 0. 09-0. 11m m程度の厚さとなった。  [0068] In this way, the region 15A including the decoloring agent 16 and the uneven portion 15D are formed on the surface of the ultrathin artificial skin material 11 made of urethane coagulation, and the ultrathin artificial skin material 15 is produced. did.厚 The thickness of the erased ultrathin artificial skin material 15 increased by about 0.03-0.035mm in the region 15A containing the eraser 16, and the total thickness of the erased ultrathin artificial skin material 15 was 0.09. -0. Thickness of about 11mm.
[0069] 第 4工程として、ネット型 20に成形する前のネット部材を装着者の頭部形状に成形 するために、頭部形状の石膏型 61の上にネット部材を張り樹脂加工を行う。図 15は 、頭部形状の石膏型 61の上にネット部材を張り、固定用針具 62を用いて固定した状 態の側面図である。  [0069] As a fourth step, in order to form the net member before being molded into the net mold 20 into the shape of the wearer's head, the net member is stretched on the head-shaped gypsum mold 61 and subjected to resin processing. FIG. 15 is a side view of a state in which a net member is stretched on a head-shaped plaster mold 61 and fixed using a fixing needle tool 62.
[0070] 樹脂加工は、図 15のように用意したかつら装着者の頭部形状の石膏型 61にナイ口 ン製力 なるネット部材を張って固定した後、そのネット部材の上力 熱硬化性ウレタ ン榭脂溶液を塗布し、加熱温度 100°Cで 8時間乾燥させて成形し、ネット型 20を得た [0070] Resin processing is carried out by fixing a net member, which is a lip maker, to a gypsum mold 61 of the head shape of the wig wearer prepared as shown in FIG. Ureta The resin was applied and dried at a heating temperature of 100 ° C for 8 hours to form a net mold 20.
[0071] 次に、石膏型 61からネット型 20を剥がして超音波加工を行った。超音波加工とは、 ネット型 20を構成する糸が交差する部分を超音波と加圧によって溶着し、交差する 部分を固定する処理である。超音波加工を行った際、成形したネット型 20の形が崩 れてしまうと後述する第 5工程に支障が生じる。そこで、石膏型 61の上に超音波加工 を行ったネット型 20を前額部、後頭部、左右側頭部の位置に合わせて張って固定し 、熱硬化性ウレタン榭脂溶液をその上力 塗布し、加熱温度 100°Cで 4時間乾燥さ せて成形を行った。 [0071] Next, the net mold 20 was peeled off from the gypsum mold 61, and ultrasonic processing was performed. The ultrasonic processing is a process in which the intersecting portions of the net 20 are welded by ultrasonic waves and pressure, and the intersecting portions are fixed. If the shape of the molded net mold 20 breaks down during ultrasonic processing, the fifth process described later will be hindered. Therefore, the net type 20 that has been ultrasonically processed on the gypsum mold 61 is stretched and fixed in accordance with the positions of the forehead, occipital region, and left and right side of the head, and a thermosetting urethane resin solution is applied to it. Then, it was molded by drying at a heating temperature of 100 ° C for 4 hours.
本実施例ではネット部材としてナイロン製ネットを用いたので、熱硬化性ウレタン榭 脂溶液による樹脂加工後に超音波加工及び再成形処理工程を行った力 これはナ ィロンの吸水性が高いために寸法安定性が悪ぐまた頭部形状に成形した形状が崩 れ易いので、それを防止するためである。ナイロン製以外のネットの場合は、吸水性 が高く寸法安定性が良好なので、熱硬化性ウレタン榭脂溶液による樹脂加工だけで ちょい。  In this example, since a net made of nylon was used as the net member, the force of ultrasonic processing and re-molding process after resin processing with thermosetting urethane resin solution. This is due to the high water absorption of nylon. This is to prevent the stability from being deteriorated and the shape formed into the head shape to be easily broken. Non-nylon nets have high water absorption and good dimensional stability, so it is only necessary to process the resin with a thermosetting urethane resin solution.
なお、成形に用いたネット部材の糸径は 220Dであり、メッシュは 25メッシュ程度 (本 Zインチ)であった。成形に用いるネット部材は頭部形状の型を付けることができる素 材であればよぐ糸径ゃメッシュの数値は適宜変更可能である。  The net diameter of the net member used for molding was 220D, and the mesh was about 25 mesh (this Z-inch). As long as the net member used for forming is a material that can be provided with a head-shaped mold, the value of the thread diameter and mesh can be changed as appropriate.
[0072] 第 5工程として、前記第 1〜第 3工程で作製した艷消し極薄人工皮膚材 15を下に、 第 4工程で作製した成形済みのネット型 20を上にして重ね合わせる。図 16は、前記 第 1〜第 3工程で作製した石膏型 61にセットした艷消し極薄人工皮膚材 15の上から 、前記第 4工程で作製したネット型 20を重ねた状態を示す側面図である。そして、重 ね合わせた艷消し極薄人工皮膚材 15とネット型 20を所定の位置に所定の幅で接着 し、一体化する。 [0072] As the fifth step, the erased ultrathin artificial skin material 15 produced in the first to third steps is placed on the bottom, and the molded net mold 20 produced in the fourth step is overlaid. FIG. 16 is a side view showing a state in which the net mold 20 produced in the fourth process is overlaid on the erased ultrathin artificial skin material 15 set in the plaster mold 61 produced in the first to third processes. It is. Then, the superposed ultrathin artificial skin material 15 and the net mold 20 are bonded to a predetermined position with a predetermined width and integrated.
[0073] ここで、艷消し極薄人工皮膚材 15とネット型 20を一体ィ匕する処理について説明す る。  [0073] Here, the process of integrating the erased ultrathin artificial skin material 15 and the net mold 20 together will be described.
先ず、図 17に示すように、艷消し極薄人工皮膚材 15の接合部 73となる境界線に 沿ってそのフロント側に幅 3mmのマスキングテープ 74を貼る。次に、図 16及び図 18 に示すように、艷消し極薄人工皮膚材 15の上にネット型 20を重ねて所定の位置に 合わせる。そして、図 19に示すように、マスキングテープ 75, 76をネット型 20の上に 接合部 73の境界線に沿って接合部 73を挟むように貼る。図 20は図 19の A— 線 断面図である。マスキングテープ 74を前頭部側の境界線に沿って予め貼る理由は、 艷消し極薄人工皮膚材 15に一体ィ匕溶剤が付着して、艷消し極薄人工皮膚材 15の 美観を損ねてしまうのを防止するためである。 First, as shown in FIG. 17, a masking tape 74 having a width of 3 mm is pasted on the front side along the boundary line that becomes the joint 73 of the erased ultrathin artificial skin material 15. Next, Fig. 16 and Fig. 18 As shown in Fig. 4, the net mold 20 is superimposed on the erased ultrathin artificial skin material 15 and adjusted to a predetermined position. Then, as shown in FIG. 19, masking tapes 75 and 76 are pasted on the net mold 20 so as to sandwich the joint 73 along the boundary line of the joint 73. FIG. 20 is a cross-sectional view taken along line A— of FIG. The reason for applying masking tape 74 in advance along the border on the frontal side is that the integrated ultra-thin artificial skin material 15 adheres to the integrated ultra-thin artificial skin material 15 and damages the aesthetic appearance of the ultra-thin artificial skin material 15 This is to prevent it from falling out.
[0074] 艷消し極薄人工皮膚材 15とネット型 20とを一体ィ匕させるために、ウレタンエラストマ 一を DMF及び MEKに溶解させ、防黴剤を添加して作製した一体ィ匕用溶剤を、接 合部 73に塗布し、加熱温度 60°Cで 30分間乾燥させた。次に、ウレタンエラストマ一 を DMF及び MEKに溶解させ、防黴剤を添加した溶液に、さらに、艷消し剤 16となる 粉状シリカ(平均粒径 3. 1 μ m〜4. 1 m)と、紫外線吸収剤と、酸化防止剤を添加 した艷消し用溶液を、一体化溶剤を塗布した位置に塗布し、加熱温度 60°Cで 2時間 乾燥させた。シリカの重量は、ウレタンエラストマ一重量に対して、約 21%であった。 一体化後、図 21、図 22のように、艷消し極薄人工皮膚材 15に位置する不要なネット 部材 20a (図 19参照)を切除する。  [0074] In order to unite the ultrathin artificial skin material 15 and the net mold 20, the urethane elastomer was dissolved in DMF and MEK, and an antifoaming agent prepared by adding an antifungal agent was used. Then, it was applied to the joint 73 and dried at a heating temperature of 60 ° C. for 30 minutes. Next, the urethane elastomer is dissolved in DMF and MEK, and the solution added with the antifungal agent is further mixed with powdered silica (average particle size: 3.1 μm to 4.1 m) as the antifoaming agent 16. Then, an erasing solution containing an ultraviolet absorber and an antioxidant was applied to the position where the integrated solvent was applied and dried at a heating temperature of 60 ° C. for 2 hours. The weight of silica was about 21% based on one weight of urethane elastomer. After the integration, an unnecessary net member 20a (see FIG. 19) located on the erased ultrathin artificial skin material 15 is excised as shown in FIGS.
[0075] 艷消し極薄人工皮膚材 15とネット型 20との接合部 73は、縫着によって形成するこ ともできる。先ず、図 16及び図 23に示すように、艷消し極薄人工皮膚材 15の上にネ ット型 20を重ねて所定の位置に合わせる。次に、図 23に示した接合部 73^ に沿つ てナイロンフィラメント糸によって手縫いによる仮縫 ヽを行、、石膏型 61から艷消し極 薄人工皮膚材 15とネット型 20とを剥がす。  [0075] The joint 73 between the ultrathin artificial skin material 15 and the net 20 can also be formed by sewing. First, as shown in FIG. 16 and FIG. 23, a net mold 20 is overlapped on the erased ultrathin artificial skin material 15 and is adjusted to a predetermined position. Next, along the joint 73 ^ shown in FIG. 23, a hand-sewn temporary sew is performed with nylon filament thread, and the ultrathin artificial skin material 15 and the net mold 20 are peeled off from the gypsum mold 61.
仮縫いを行った接合部 73' に沿って、ナイロンフィラメント糸を用いてミシンによる 本縫いを行う。本縫い後、最初に仮縫いを行った部分に残っているナイロンフィラメン ト糸を抜いて取り除く。  Along the joint 73 'where the temporary sewing was performed, a sewing machine is used for sewing with nylon filament thread. After the main sewing, remove the nylon filament thread remaining in the part where the temporary sewing was performed first.
ここで、ナイロンフィラメント糸の糸径は 50dxのものを使用した。ミシンによる本縫い を行うためのナイロンフィラメント糸は、接合部の露見を防ぐため、ネット型 20の色に 合わせて露見しない色を選択し、且つ、艷が発生しないものを用いるのが望ましい。 仮縫 ヽに使用するナイロンフィラメント糸はミシンによる縫製後に取り除く工程がある ため、艷消し極薄人工皮膚材 15及びネット型 20との見分けがつくような色が付いて いるものを用いることが好ましい。一体化後、図 24及び図 25のように、艷消し極薄人 ェ皮膚材 15に位置する不要なネット部分 20a (図 23参照)を切除する。 Here, a nylon filament yarn having a diameter of 50 dx was used. For the nylon filament thread for performing the main sewing with the sewing machine, it is desirable to select a color that does not expose in accordance with the color of the net type 20 and to prevent wrinkles from occurring in order to prevent the exposed portion of the joint from being exposed. Nylon filament thread used for temporary sewing ヽ has a process to be removed after sewing with a sewing machine, so it has a color that can be distinguished from erased ultrathin artificial skin material 15 and net type 20 It is preferable to use what is. After the integration, as shown in FIGS. 24 and 25, the unnecessary net portion 20a (see FIG. 23) located on the erased ultrathin skin material 15 is cut off.
[0076] 第 6工程として、かつら装着者の頭部形状雄型に第 1〜第 5工程によって作製した かつらベースを固定し、艷消し極薄人工皮膚材 15並びにネット型 20にナイロン製の 人工毛髪 12の 1本又は数本をまとめて折り返して、艷消し極薄人工皮膚材 15には V 植えで植設し、ネット型 20にはネットを構成する糸と毛髪 12を結びつけて植設した。 V植えとは、図 3に示すように毛髪 12を極薄人工皮膚材 11の表面側力も裏面に貫通 して植設し、再び極薄人工皮膚材 1 1の表面側に引き抜くことにより、 V字状または U 字状に植設するものである。ネット型 20及び接合部 73に毛髪を植設する方法は、紐 などの結び方で公知のひばり結び、巻き結びを行う。  [0076] As the sixth step, the wig base produced by the first to fifth steps is fixed to the head-shaped male mold of the wig wearer, and the artificial ultrathin artificial skin material 15 and the net mold 20 are made of nylon. One or several of the hairs 12 are folded back together, and the wiping ultrathin artificial skin material 15 is planted by V planting, and the net type 20 is planted by tying the yarns and hairs 12 constituting the net. . As shown in Fig. 3, V planting is performed by planting hair 12 with the surface side force of ultrathin artificial skin material 11 penetrating the back side and pulling it out to the surface side of ultrathin artificial skin material 11 again. It is to be planted in a letter or U shape. As a method of planting hair in the net mold 20 and the joint 73, a known method of tying and tying knots is used.
[0077] 第 7工程として、毛髪 12を植設した艷消し極薄人工皮膚材 15の裏面に接着層 30 を形成する。具体的には、毛髪を植設したかつらベース la又は lbを裏返してかつら 装着者の頭部形状雄型にセットする。  [0077] As a seventh step, an adhesive layer 30 is formed on the back surface of the erased ultrathin artificial skin material 15 in which the hair 12 is implanted. Specifically, the wig base la or lb on which the hair is planted is turned over and set on the head-shaped male mold of the wig wearer.
図 2 (A)、図 2 (B)に示すような人工皮膚の前縁の所定幅 a或 、は前縁の一部 β に接着層 30を形成する場合、接着層 30を形成しない部分に植設した毛髪の針足部 12Aを艷消し極薄人工皮膚材 15の裏面に固定するための毛止め用ウレタン溶液を 所定回数塗布し、加熱温度 60°Cで所定時間乾燥した。その後、人工皮膚の前縁の 所定幅 α又は前縁の一部 ι8に接着層 30を形成する。接着層 30を形成する幅は、 1 . 0cm以上であればよい。このような場合の極薄人工皮膚 10Bの断面は図 26に示す ようになる。毛髪 12の針足部 12Aがウレタン溶液 50により艷消し極薄人工皮膚材 15 に固定され、このウレタン溶液 50の上に接着層 30が塗布されている。  When the adhesive layer 30 is formed on the predetermined width a of the leading edge of the artificial skin as shown in Fig. 2 (A) and Fig. 2 (B) or on a part β of the leading edge, the portion where the adhesive layer 30 is not formed is formed. The needle foot part 12A of the implanted hair was erased and a urethane solution for hair fixing for fixing to the back surface of the ultrathin artificial skin material 15 was applied a predetermined number of times and dried at a heating temperature of 60 ° C. for a predetermined time. Thereafter, the adhesive layer 30 is formed on the predetermined width α of the front edge of the artificial skin or a part ι8 of the front edge. The width for forming the adhesive layer 30 may be 1.0 cm or more. The cross section of the ultrathin artificial skin 10B in such a case is as shown in FIG. The needle foot 12A of the hair 12 is erased by the urethane solution 50 and fixed to the ultrathin artificial skin material 15, and the adhesive layer 30 is applied on the urethane solution 50.
[0078] 艷消し極薄人工皮膚材 15裏面の全面に接着層 30を形成する場合は、図 3及び図 4に示すように、毛止め用ウレタン溶液 50を塗布せずに接着層 30を形成する。毛止 め用ウレタン溶液 50を塗布しな ヽ理由は、接着層 30が毛髪の針足部 12Aの固着機 能を有しており、接着層 30を形成することにより艷消し極薄人工皮膚材 15裏面の全 面に植設した毛髪の針足部 12Aが全て固着されるからである。  [0078] The ultrathin artificial skin material 15 When the adhesive layer 30 is formed on the entire back surface, as shown in FIGS. 3 and 4, the adhesive layer 30 is formed without applying the anti-hair urethane solution 50. To do. The reason for not applying the hair-blocking urethane solution 50 is that the adhesive layer 30 has a function of fixing the needle foot 12A of the hair, and the ultra-thin artificial skin material that disappears by forming the adhesive layer 30. This is because all the needle feet 12A of the hair planted on the entire back surface are fixed.
[0079] 接着層 30を形成するための接着剤は、主剤と硬化剤とからなる 2液混合型ウレタン 榭脂系接着剤モノマーと、艷消し極薄人工皮膚材 15の溶剤である DMFと、を混合 したものを用いた。主剤としてはウレタン榭脂を主成分とするポリオール、硬化剤とし ては、ポリイソシァネートを主成分とした。上記 2液混合型ウレタン榭脂系接着剤の主 剤と硬化剤と溶剤である DMFとを混合撹拌した。この溶液を、室温で約 1〜2時間静 置し反応を進めた。静置後の溶液の粘度は、 2000〜3000cps程度が適当であった 。この接着剤の溶液を、艷消しかつらベース la、 lbの裏面にハケ塗りし、 80°Cで 10 〜15時間乾燥させ、乾燥後室温まで冷却した。このようにして、約 0. 05-0. 2mm の接着層 30を形成した。 [0079] The adhesive for forming the adhesive layer 30 is composed of a two-component mixed urethane oleaginous adhesive monomer composed of a main agent and a curing agent, DMF, which is a solvent for the erasing ultrathin artificial skin material 15, Mixed What was done was used. The main component is a polyol mainly composed of urethane resin, and the curing agent is mainly a polyisocyanate. The main component of the two-component mixed urethane-resin adhesive, the curing agent, and DMF as a solvent were mixed and stirred. This solution was allowed to stand at room temperature for about 1 to 2 hours to proceed the reaction. The viscosity of the solution after standing was suitably about 2000 to 3000 cps. The adhesive solution was brushed on the back of the erasing wig base la, lb, dried at 80 ° C. for 10-15 hours, and then cooled to room temperature. In this way, an adhesive layer 30 of about 0.05-0.2 mm was formed.
[0080] 第 8工程として、ネット型 20の不要な部分を切除する。また、かつらの輪郭を形成す る外縁部 72に沿って艷消し極薄人工皮膚材 15のはみ出し部分を切除する。切除の 際に、艷消し極薄人工皮膚材 15の前縁の形状処理を行う。形状の寸法について、 図 6のように頂点 51からそれに隣接する谷間 52までの長手方向に対する垂直方向 の長さ Aは 2. Omm程度、頂点 5 laからそれに隣接する他の頂点 5 lbまでの長手方 向の長さ Bは 10. Omm程度となる波形状とした。  [0080] As an eighth step, unnecessary portions of the net mold 20 are cut off. Further, the protruding portion of the ultrathin artificial skin material 15 is cut off along the outer edge portion 72 that forms the outline of the wig. At the time of resection, shape processing of the leading edge of the erased ultrathin artificial skin material 15 is performed. Regarding the dimensions of the shape, the length A in the vertical direction from the vertex 51 to the adjacent valley 52 as shown in Fig. 6 is about 2. Omm, the length from the vertex 5 la to the other adjacent vertex 5 lb The length B in the direction is about 10. Omm.

The D direction is the frontal direction of the wig, the front part is provided with an ultrathin artificial skin material 15 and the rear part is provided with a net-type 20 material. The material 15 and the net mold 20 are joined. In addition, an adhesive layer 30 is formed on the front edge of the artificial skin material 15, and the corrugated shape is processed.
[0082] 本実施例では、艷消し極薄人工皮膚材 15の上にネット型 20を重ね合わせて一体 化しているため、接合部 73では図 27のように、ネット型 20が艷消し極薄人工皮膚材 15の上に重なるように一体ィ匕されているが、図 29のように、艷消し極薄人工皮膚材 1 5が上になり、ネット型 20が下となるように一体ィ匕して作製することも可能である。  [0082] In this embodiment, the net type 20 is superposed and integrated on the erased ultrathin artificial skin material 15, so that the net type 20 is erased and ultrathin as shown in FIG. It is integrated so that it overlaps with artificial skin material 15, but as shown in Fig. 29, it is integrated so that the erased ultrathin artificial skin material 15 is on the top and the net type 20 is on the bottom. It is also possible to make it.
[0083] 上記実施例におけるかつら 10の接着層 30に対する、かつらベース la, lb及び毛 髪 12の針足部 12Aの固着強度を調べた。かつらベース la, lbと接着層 30との接着 力は、 180gf/mm2程度あった。毛髪 12の針足部 12Aと、接着層 30との固着力は 、 lOgfZmm2程度であった。 [0083] The adhesion strength of the wig base la, lb and the needle foot portion 12A of the hair 12 to the adhesive layer 30 of the wig 10 in the above example was examined. The adhesive strength between the wig base la, lb and the adhesive layer 30 was about 180 gf / mm 2 . A needle foot portion 12A of the hair 12, the fixing strength between the adhesive layer 30 was 2 about LOgfZmm.
また、かつらベース la, lbと接着層 30との接着力を、人の手による引き剥がしによ る方法で調べたところ、かつらベース la, lbから接着層 30は容易には剥がれず、剥 離不能に接着されていることが分力つた。さらに、かつらベース la, lbと毛髪 12の針 足部 12Aとの固着力を、毛髪 12の人手による引き抜きによる方法で調べた。毛髪 12 の針足部 12Aのかつらベース la, lbへの接着は、かつらベース la, lb及び接着層 30との接着力よりは弱いが、毛髪 12をブラッシングしても抜け落ちることは無く充分 な固着力を有することが分かった。 In addition, the adhesive strength between the wig base la, lb and the adhesive layer 30 can be removed by manual peeling. As a result, it was found that the adhesive layer 30 was not easily peeled off from the wig base la, lb, and was adhered in a non-peelable manner. Furthermore, the adhesive strength between the wig base la, lb and the needle foot 12A of the hair 12 was examined by a method of manually pulling out the hair 12.
