Description

本発明は、例えばかつらに用いられる人工毛髪、及びかつらに関する。 The present invention relates to, for example, artificial hair used for wigs and wigs.

従来、かつら等に用いられる人工毛髪の素材としては、PET(ポリエチレンテレフタレート)が広く知られている。このPETは、カールした状態を維持する性質であるカール性、耐久性などに優れている。しかしながら、人工毛髪はあたかも人の地毛であるかのように認識されることが必要であるにも関わらず、PETは、人の地毛にはない光沢を有し、人の地毛であるかのように認識されるものとはいえない。なお、PETである人工毛髪素材にアルカリ減量加工を行い表面に凹凸を設けることで光沢を抑えることはできるが、それでもなお、人の地毛であるかのように認識されるとはいい難い。 Conventionally, PET (polyethylene terephthalate) is widely known as a material for artificial hair used for wigs and the like. This PET is excellent in curl property, durability and the like, which are properties of maintaining a curled state. However, although artificial hair needs to be recognized as if it were human hair, PET has a luster that human hair does not have and is human hair. It cannot be said that it is recognized as such. Although it is possible to suppress the gloss by applying an alkali weight loss process to the artificial hair material which is PET to provide unevenness on the surface, it is still difficult to say that the artificial hair material is recognized as if it were human hair.

なお、芯部及び鞘部の2層構造となっている人工毛髪が知られている(例えば、特許文献1参照)。このような2層構造の人工毛髪は、製造に手間を要する反面、芯部及び鞘部の両方の特性を得られる。 It should be noted that artificial hair having a two-layer structure of a core portion and a sheath portion is known (see, for example, Patent Document 1). Such a two-layered artificial hair requires a lot of labor to manufacture, but on the other hand, it can obtain the characteristics of both a core portion and a sheath portion.

特許4823237号公報Japanese Patent No. 4823237

上述のように、PETからなる人工毛髪は、人の地毛と認識されにくい。一方、PBT(ポリブチレンテレフタレート)又はPTT(ポリトリメチレンテレフタレート)からなる人工毛髪は、風合い(外観、触感など)の点で、PETよりも人の地毛と認識されやすい。しかしながら、PBT又はPTTからなる人工毛髪は、カール性、耐久性などの点では、PETからなる人工毛髪に劣るといえる。 As described above, artificial hair made of PET is difficult to be recognized as human hair. On the other hand, artificial hair made of PBT (polybutylene terephthalate) or PTT (polytrimethylene terephthalate) is more easily recognized as human hair than PET in terms of texture (appearance, touch, etc.). However, it can be said that the artificial hair made of PBT or PTT is inferior to the artificial hair made of PET in terms of curl property and durability.

本発明の目的は、カール性及び耐久性に優れ、且つ、人の地毛であるかのように認識される人工毛髪及びこの人工毛髪を備えるかつらを提供することである。 An object of the present invention is to provide artificial hair which is excellent in curl and durability and which is recognized as human hair, and a wig provided with the artificial hair.

1つの観点では、人工毛髪は、表面に位置する第1の層と、前記第1の層に囲まれた第2の層と、を含む複数層構造を呈し、前記第1の層の主成分は、ポリブチレンテレフタレート又はポリトリメチレンテレフタレートであり、前記第2の層の主成分は、ポリエチレンテレフタレートである。 From one aspect, the artificial hair exhibits a multi-layer structure including a first layer located on the surface and a second layer surrounded by the first layer, and is a main component of the first layer. Is polybutylene terephthalate or polytrimethylene terephthalate, and the main component of the second layer is polyethylene terephthalate.

また、前記人工毛髪において、前記第1の層の主成分は、前記ポリブチレンテレフタレートであるとよい。
また、前記人工毛髪において、前記第2の層は、前記人工毛髪の中心に位置する芯部であるとよい。
Further, in the artificial hair, the main component of the first layer is preferably polybutylene terephthalate.
Further, in the artificial hair, the second layer may be a core portion located at the center of the artificial hair.

別の観点では、かつらは、前記人工毛髪と、前記人工毛髪が植毛されたかつらベースと、を備える。 In another aspect, the wig comprises the artificial hair and a wig base on which the artificial hair is transplanted.

本発明によれば、カール性及び耐久性に優れ、且つ、人の地毛であるかのように認識される人工毛髪及びこの人工毛髪を備えるかつらを提供することができる。 According to the present invention, it is possible to provide artificial hair which is excellent in curl property and durability and is recognized as if it is human hair, and a wig provided with the artificial hair.

図1に示す人工毛髪10は、表面に位置する第1の層の一例である鞘部11と、この鞘部11に囲まれた第2の層の一例である芯部12と、を含む複数層構造を呈する。
FIG. 2 is a process diagram showing a method for producing the artificial hair 10.
A plurality of artificial hairs 10 shown in FIG. 1 include a sheath portion 11 which is an example of a first layer located on the surface and a core portion 12 which is an example of a second layer surrounded by the sheath portion 11. It exhibits a layered structure.

なお、人工毛髪10は、第1の層(鞘部11)と第2の層(芯部12)との間に1つ以上の他の層が設けられていてもよいし、第2の層に囲まれた1つ以上の他の層が設けられていてもよい。 The artificial hair 10 may be provided with one or more other layers between the first layer (sheath portion 11) and the second layer (core portion 12), or the second layer. One or more other layers surrounded by may be provided.

鞘部11の主成分は、例えばPBT(ポリブチレンテレフタレート)である。但し、鞘部11の主成分がPTT(ポリトリメチレンテレフタレート)であってもよい。
芯部12の主成分は、PET(ポリエチレンテレフタレート)である。
The main component of the sheath portion 11 is, for example, PBT (polybutylene terephthalate). However, the main component of the sheath portion 11 may be PTT (polytrimethylene terephthalate).
The main component of the core portion 12 is PET (polyethylene terephthalate).

なお、芯部12は、人工毛髪10の中心に位置するが、必ずしも人工毛髪10と芯部12とが同心円を構成する必要はなく、人工毛髪10の中心に芯部12のいずれかの部分が位置してればよい。 Although the core portion 12 is located at the center of the artificial hair 10, the artificial hair 10 and the core portion 12 do not necessarily form concentric circles, and any part of the core portion 12 is located at the center of the artificial hair 10. It just needs to be located.

図2に示すように、本実施の形態に係る人工毛髪10の製造方法は、原糸である人工毛髪素材を製造する製糸工程S1と、人工毛髪素材にアルカリ減量加工を行うアルカリ減量工程S2と、人工毛髪素材を染色する染色工程S3と、を含む。 As shown in FIG. 2, the method for producing the artificial hair 10 according to the present embodiment includes a yarn making step S1 for producing an artificial hair material which is a raw yarn, and an alkali weight loss step S2 for performing an alkali weight loss process on the artificial hair material. , A dyeing step S3 for dyeing an artificial hair material.

各工程は、任意の公知の種々の手法を用いて行うことができるため、ここでは各工程の概要を説明する。
まず、製糸工程S1では、溶融混合紡糸法にて、PET及びPBTのホモのポリエステルポリマー(材料A)に対し、ジカルボン酸成分としてイソフタル酸、スルホイソフタル酸塩、またジオール成分としてポリエチレングリコール、ポリプロピレングリコール、ポリテトラメチレングリコールなどのポリアルキレングリコールを用い、ジカルボン酸成分及び/又はジオール成分を共重合してなる共重合PETなど(材料B)を少量混合(ペレットでドライブレンド)し、繊維内に材料Bを分散させるとよい。
Since each step can be performed by using any known various methods, an outline of each step will be described here.
First, in the yarn-making step S1, the dicarboxylic acid component is isophthalic acid and sulfoisophthalate, and the diol component is polyethylene glycol and polypropylene glycol with respect to the PET and PBT homopolyester polymer (material A) by the melt-mixed spinning method. , Polyalkylene glycol such as polytetramethylene glycol is used, and a small amount of copolymerized PET or the like (material B) obtained by copolymerizing a dicarboxylic acid component and / or a diol component is mixed (dry blended with pellets) to form a material in the fiber. B should be dispersed.

その分散状態としては、材料Bは人工毛髪素材中で液滴状や筋状態で分布する。人工毛髪素材は、延伸により長針状、筋状に変形される。スルホイソフタル酸塩は、例えば1〜5mol%であり、アルキレングリコールは、例えば3〜15重量%であることが望ましい。 As the dispersed state, the material B is distributed in the artificial hair material in the form of droplets or streaks. The artificial hair material is deformed into a long needle shape or a streak shape by stretching. It is desirable that the sulfoisophthalate is, for example, 1 to 5 mol%, and the alkylene glycol is, for example, 3 to 15% by weight.

また、艶消し剤の一例として、シリカ(SiO)及び酸化チタン(TiO)を含有させるとよい。これらの艶消し剤は、合計1重量%以下で混合されていることが望ましい。更に、芯成分及び鞘成分には上記の艶消し剤の他に、安定剤、紫外線吸収剤、流動改善剤、着色剤などの添加剤を加えることもできる。 Further, as an example of the matting agent, silica (SiO 2 ) and titanium oxide (TiO 2 ) may be contained. It is desirable that these matting agents are mixed in a total amount of 1% by weight or less. Further, in addition to the above-mentioned matting agent, additives such as a stabilizer, an ultraviolet absorber, a flow improver, and a colorant can be added to the core component and the sheath component.

また、あくまで一例であるが、人工毛髪素材の製糸段階では、鞘部11となる部分が占める体積割合が30〜50%で、且つ、芯部12となる部分が占める体積割合が50〜70%であることが望ましい。 Further, as an example only, at the silk-reeling stage of the artificial hair material, the volume ratio of the portion serving as the sheath portion 11 is 30 to 50%, and the volume ratio occupied by the portion serving as the core portion 12 is 50 to 70%. Is desirable.

次に、アルカリ減量工程S2は、人工毛髪素材の表面をアルカリ加水分解する工程であり、例えば、人工毛髪素材を100℃以上に加熱されたアルカリ溶液の中に浸し、アルカリ減量処理を行う。これにより、製造される人工毛髪10の鞘部11の表面に、微細な凹部が形成される。 Next, the alkali weight loss step S2 is a step of alkaline hydrolysis of the surface of the artificial hair material. For example, the artificial hair material is immersed in an alkaline solution heated to 100 ° C. or higher to perform an alkali weight loss treatment. As a result, fine recesses are formed on the surface of the sheath portion 11 of the artificial hair 10 to be manufactured.

最後に、染色工程S3では、上述のようにアルカリ減量加工が行われた人工毛髪素材に黒色、茶色などの任意の色に染色を行う。
図3は、本実施の形態に係るかつら1を示す平面図である。
Finally, in the dyeing step S3, the artificial hair material subjected to the alkali weight loss processing as described above is dyed in an arbitrary color such as black or brown.
FIG. 3 is a plan view showing a wig 1 according to the present embodiment.

図3に示すかつら1は、複数の上述の人工毛髪10と、この人工毛髪10が植毛されたかつらベース20と、を備える。かつら1は、図3に示すようにかつら装着者の頭部のほぼ全体に配置されるかつら1であってもよいし、かつら装着者の頭部の全体又は一部に配置される全頭かつら又は部分かつらであってもよい。 The wig 1 shown in FIG. 3 includes a plurality of the above-mentioned artificial hairs 10 and a wig base 20 on which the artificial hairs 10 are transplanted. As shown in FIG. 3, the wig 1 may be a wig 1 placed on almost the entire head of the wig wearer, or a full-head wig placed on the whole or a part of the head of the wig wearer. Or it may be a partial wig.

かつらベース20は、本体部21と、周縁部22と、分け目部23と、を有する。かつらベース本体部21には、人工毛髪10が植毛されている。なお、図3において、人工毛髪10は、本体部21、周縁部22、及び分け目部23のそれぞれに1本又は2本のみ図示されているが、実際には、例えば密集するようにかつらベース20に植毛される。 The wig base 20 has a main body portion 21, a peripheral portion 22, and a dividing portion 23. Artificial hair 10 is planted on the wig base main body 21. In FIG. 3, only one or two artificial hairs 10 are shown for each of the main body portion 21, the peripheral portion 22, and the dividing portion 23, but in reality, for example, the wig base 20 is densely packed. Hair is transplanted to.

周縁部22は、本体部21とは異なる部材から形成されているか、或いは、本体部21を折り返すことで形成されている。分け目部23は、例えば、合成樹脂からなる人工皮膚により形成されている。また、分け目部23は、本体部21を刳り貫いた部分に配置されているか、或いは、本体部21上に重なるように配置されている。 The peripheral edge portion 22 is formed of a member different from that of the main body portion 21, or is formed by folding back the main body portion 21. The dividing portion 23 is formed of, for example, an artificial skin made of a synthetic resin. Further, the dividing portion 23 is arranged in a portion formed through the main body portion 21, or is arranged so as to overlap the main body portion 21.

なお、本実施の形態では、本体部21、周縁部22、及び分け目部22が設けられたかつらベース20を一例として説明しているが、かつらベース20は、本体部21のみからなるかつらベースや、その他のかつらベースであってもよい。 In the present embodiment, the wig base 20 provided with the main body portion 21, the peripheral portion 22, and the dividing portion 22 is described as an example, but the wig base 20 is a wig base composed of only the main body portion 21. , Other wig bases may be used.

以上説明した本実施の形態では、人工毛髪10は、表面に位置する第1の層の一例である鞘部11と、この鞘部11に囲まれた第2の層の一例である芯部12と、を含む複数層構造を呈する。また、鞘部11の主成分は、PBT又はPTTであり、芯部12の主成分は、PETである。そのため、PBT又はPTTを主成分とする鞘部11が人工毛髪10の表面に位置することで、風合い(外観、触感など)の点で、鞘部11がPETからなる場合よりも人の地毛と認識されやすくなる。また、PETを主成分とする芯部12が人工毛髪10の内部に位置することによって、芯部12がPBTやPTTからなる場合よりも、カール性、耐久性などを高めることができる。更には、鞘部11がPBT又はPTT、特にPTTを主成分とする場合、PETを主成分とする芯部12のカールに追従して変形しやすくなり、この点でもカール性を高めることができる。 In the present embodiment described above, the artificial hair 10 has a sheath portion 11 which is an example of a first layer located on the surface and a core portion 12 which is an example of a second layer surrounded by the sheath portion 11. It exhibits a multi-layer structure including and. The main component of the sheath portion 11 is PBT or PTT, and the main component of the core portion 12 is PET. Therefore, since the sheath portion 11 containing PBT or PTT as the main component is located on the surface of the artificial hair 10, in terms of texture (appearance, touch, etc.), the sheath portion 11 is made of human hair as compared with the case where the sheath portion 11 is made of PET. It becomes easy to be recognized. Further, since the core portion 12 containing PET as a main component is located inside the artificial hair 10, the curl property, durability and the like can be improved as compared with the case where the core portion 12 is made of PBT or PTT. Further, when the sheath portion 11 contains PBT or PTT, particularly PTT as a main component, it easily deforms following the curl of the core portion 12 containing PET as a main component, and the curl property can be enhanced in this respect as well. ..

よって、本実施の形態によれば、カール性及び耐久性に優れ、且つ、人の地毛であるかのように認識される人工毛髪10及びこの人工毛髪10を備えるかつら1を提供することができる。 Therefore, according to the present embodiment, it is possible to provide an artificial hair 10 which is excellent in curl property and durability and is recognized as if it is human hair, and a wig 1 provided with the artificial hair 10. it can.

また、本実施の形態では、表面に位置する第1の層(鞘部11)に囲まれた第2の層の一例が、人工毛髪10の中心に位置する芯部12である。そのため、PETを主成分とする芯部12によって、人工毛髪10のカール性、耐久性などを十分に高めることができる。 Further, in the present embodiment, an example of the second layer surrounded by the first layer (sheath portion 11) located on the surface is the core portion 12 located at the center of the artificial hair 10. Therefore, the curl property, durability, and the like of the artificial hair 10 can be sufficiently enhanced by the core portion 12 containing PET as a main component.
