【発明の属する技術分野】
本発明は、かつら、ヘアピース、人形用頭髪等に用いられるアクリル系人工毛髪用繊維に関し、さらには、従来のアクリル系人工毛髪用繊維に比べ、著しく分繊性に優れ、且つヌメリ性のあるソフトな触感と、自然な光沢を有し、櫛通りに優れたアクリル系人工毛髪用繊維に関する。
【０００２】
【従来の技術】
一般にカツラ、ヘアピース、人形用頭髪等に使用される人工毛髪用繊維としては、アクリル系繊維、塩化ビニル繊維、塩化ビニリデン繊維、ポリエステル繊維、ナイロン繊維、ポリプロピレン繊維等がある。これらの人工毛髪用繊維をカツラ、ヘアピース、人形毛髪用途に供する場合、分繊性、光沢、触感・風合い、櫛通り、カール性能の良さ等が品質の主な要求特性となる。これらの特性は勿論、繊維自体の特質にも影響されるが、使用する油剤に負うところが大である。特にこの分野でアクリル系繊維は、その人毛・獣毛ライクな風合いの為に、主要な地位を占めている。しかし、従来アクリル系繊維では、一般的にポリエーテル系油剤等が用いられており、アクリル系繊維の湿式紡糸に際しては、乾燥工程で一本一本の繊維が融着し易く、分繊性が劣るという難点があった（この場合、分繊性が良いというのは１本、１本の繊維が融着せず分離している状態をいう）。分繊性が悪いと櫛の通りが悪かったり、櫛を通した時毛切れの原因になるので、分繊性は人工毛髪用繊維の最重要な品質項目の一つである。
【０００３】
これらの解決のために、例えば繊維中に酢酸セルロースや水酸化アルミニウム、酸化アルミニウム、酸化マグネシウム、および酸化珪素等の艶消し剤を添加する様な方法等が提案されているが、添加量が多いと繊維のガサツキ感が増大し、櫛通り性が悪化したりする傾向にある。また、昨今好まれる様になってきた光沢のある人工毛髪用繊維では、艶消し剤の添加量が多くできないため、良好な分繊性が得られない問題があった。またシリコーン系油剤を単独で使用すると確かに分繊性は向上するが、逆に繊維が滑りすぎ不自然な触感を与え、且つカールが纏まらない問題があった。このように分繊性、触感、櫛通り性、カール性能等の全てを満足できる毛髪用繊維性能を具備したアクリル系人工毛髪用繊維は得られていないのが現状であった。
【０００４】
【発明が解決しようとする課題】
本発明の目的は、従来のアクリル系人工毛髪用繊維に比べ著しく分繊性が良好で、櫛通り性に優れ、且つヌメリ性のあるソフトな触感と自然な光沢を有するアクリル系人工毛髪用繊維を提供することにある。
【０００５】
【課題を解決するための手段】
本発明者らは一般的にアクリル系繊維の柔軟仕上げ剤として使用されるポリアミンポリアミド系油剤に着目し、鋭意検討した結果、湿式紡糸でも本油剤を使用すれば、従来よりも著しく分繊性が良好で、且つヌメリ性のあるソフトな触感を有するアクリル系人工毛髪用繊維が得られる事を見いだした。ポリアミンポリアミド系柔軟剤は、繊維間の摩擦係数を引き下げ、繊維の触感にヌメリ性与え、繊維を柔らかくする作用を有する。しかし、反面、ポリアミンポリアミド系柔軟剤は、プラスティック製の櫛を使用した際に繊維の先端で毛がもつれて櫛が通り難いという重大な問題があった。この為、本発明者らはさらに検討を重ねた結果、シリコーン系油剤を併用することで櫛通り性を改善し、且つアクリル系人工毛髪用繊維の欠点であった分繊性をも改善し、人工毛髪用繊維として理想的なアクリル系人工毛髪用繊維の開発に成功し、本発明に到達した。
【０００６】
本発明者らは、分繊性が良好で、櫛通りに優れ、ヌメリ性のあるソフトな触感と自然な光沢を有するアクリル系人工毛髪用繊維を鋭意検討した結果、油剤としてポリアミンポリアミド系柔軟剤が太デニールのアクリル系湿式紡糸繊維の欠点であった分繊性を著しく改善し、且つヌメリ性のあるソフトな触感を与え、さらにシリコ−ン系油剤を当該ポリアミンポリアミド系柔軟剤に混合せしめることで、櫛通り性、特に櫛を通したときの毛先でのもつれを防止する効果があることを見い出し、本発明を完成するに至った。
【０００７】
すなわち本発明は、ポリアミンポリアミド系柔軟剤（Ａ）を主成分とする油剤に、その固形分に対して０．１〜１０重量％のシリコーン系油剤（Ｂ）を加えた乳化分散液を、繊維乾燥重量に対し固形分で０．０５〜２．０重量％付着してなるアクリル系人工毛髪用繊維である。前記ポリアミンポリアミド系柔軟剤（Ａ）としては、下式（Ｉ）〜（ＸＩ）で表される化合物及び／又はその塩からなる群から選択された少なくとも１種であることが好ましい。

さらには、シリコーン系油剤（Ｂ）がジメチルポリシロキサン、メチルハイドジェンポリシロキサン、アミノ変性シリコーン、エポキシ変性シリコーン、カルボン酸変性シリコーン、ポリエーテル変性シリコーンからなる群の内から選択された少なくとも１種であるのがより好ましい。
【０００８】
【発明の実施の形態】
以下に、本発明をさらに詳しく説明する。本発明のアクリル系人工毛髪用繊維に用いる油剤として使用されるポリアミンポリアミド系柔軟剤（Ａ）は、分子中にアミド基とアミノ基を併せ持つ系統の油剤を指すものであり、好ましいものとしては前記式（Ｉ）〜（ＸＩ）で表される化合物及び／又はその塩からなる群の内から選択される少なくとも１種が好ましい。これらの化合物は、例えば酢酸塩、グリコール酸塩、蟻酸塩、塩酸塩、ジエチル硫酸塩等の形であっても良い。またポリアミンポリアミド系柔軟剤（Ａ）は、これらの化合物単独であっても良いし、２種類以上の混合物であっても良い。
【０００９】
次に、本発明でいうシリコーン系油剤（Ｂ）とは、カチオンタイプのポリアミンポリアミド系柔軟剤（Ａ）と混合可能で、乳化分散性を損なわない物が使用可能であり、例えば、ジメチルポリシロキサン、メチルハイドロジェンポリシロキサン、アミノ変性シリコーン、エポキシ変性シリコーン、カルボン酸変性シリコーン、ポリエーテル変性シリコーン等が挙げられる。中でも油剤の安定性、及び繊維の櫛通り性改善効果の点からジメチルポリシロキサン及びアミノ変性シリコーンがより好ましい。またシリコーン系油剤（Ｂ）の添加量は、全油剤の固形分に対して０．１〜１０重量％、より好ましくは０．３〜５重量％である。前記添加量が０．１重量％未満であると目的とする櫛通り性が得られない傾向がある。また逆に１０重量％を越えると過度に滑りすぎて人工毛髪用繊維として好ましくない傾向になる。
【００１０】
また合成繊維に付与する油剤の付着量は、油剤固形分が繊維乾燥重量に対し０．０５〜２．０重量％であるのが好ましいが、繊維素材や繊維の表面状態などによって、好ましい付着量は異なる。例えば、繊維表面に微少な凹凸が多い場合は、好ましくは０．１〜１．８重量％、さらに好ましくは０．３〜１．５重量％であり、また繊維表面が比較的平滑な場合、好ましくは、０．０７〜１．５重量％、さらに好ましくは、０．１〜１．２重量％である。油剤付着量が前記範囲より少なければ目的とするソフトな触感が得られず、櫛通り性や分繊性の改善効果が不足し、静電気が発生する。また前記範囲より多くなると触感の粘着感が増加して好ましくない上、製造工程で油剤スケールの問題が発生する傾向がある。
【００１１】
さらに、本発明に使用する油剤は、本発明の効果を損なわない限り、前記ポリアミンポリアミド系柔軟剤（Ａ）及びシリコーン系油剤（Ｂ）以外の、他種の油剤との混合物であっても良い。例えば、繊維の収束性やしっとりした風合いを付与し、また静電気の発生を防止する為に通常のポリエーテル（分子量２０００〜１５０００）を油剤の固形分組成で３５重量％以下混合しても良い。但し３５重量％を越えると繊維の粘着感と収束性が過度に強くなり、人工毛髪用繊維として好ましくない。また、本油剤の乳化分散性を向上させるために必要な界面活性剤を発明の効果を損なわない範囲で添加することが出来る。前記界面活性剤としては、例えば下式（ＸII）
【化２３】
【化２４】
【００１２】
油剤の付与方法としては通常の方法が採用可能であるが、凝固−水洗後の膨潤糸条に付与するのが良い。湿式紡糸法で紡糸された膨潤糸条とは凝固・水洗上がりの未乾燥糸条であって、繊維中に多数の空孔を有し、５０〜２００重量％以上の含水率を有する状態の糸条をいう。
【００１３】
本発明でいうアクリル系人工毛髪用繊維に使用するアクリル系共重合体は、アクリロニトリルを３０〜８０重量％含有し、塩化ビニルや塩化ビニリデンなどに代表されるハロゲン含有モノマーの少なくとも１種以上を７０〜２０重量％を含有するものが好ましく、さらにこれらと共重合可能な他のビニル系モノマー、例えばメタリルスルホン酸ソーダ、アリルスルホン酸ソーダ、スチレンスルホン酸ソーダ、アクリル酸、酢酸ビニール、メタクリル酸、アクリル酸アルキルエステル、メタクリル酸アルキルエステルを共重合せしめたものであっても良い。
【００１４】
さらに、本発明に使用するアクリル系人工毛髪用繊維の単糸繊度は１０〜１００デニールが好ましく、より好ましくは１５〜７０デニールである。単糸繊度が１００デニールを越えると、毛髪用繊維としてあまりにも硬すぎて好ましくない。また単糸繊度が１０デニール未満では比較的細繊度のものが使用される人形毛髪としても柔らかすぎて好ましくない。

BACKGROUND OF THE INVENTION
The present invention relates to an acrylic artificial hair fiber used for wigs, hairpieces, doll hairs, and the like. Furthermore, the present invention is significantly superior to conventional acrylic artificial hair fibers and has a softness and sliminess. The present invention relates to a fiber for acrylic artificial hair that has excellent tactile sensation and natural luster and is excellent as a comb.
[0002]
[Prior art]
Examples of fibers for artificial hair that are generally used for wigs, hairpieces, doll hair, etc. include acrylic fibers, vinyl chloride fibers, vinylidene chloride fibers, polyester fibers, nylon fibers, and polypropylene fibers. When these artificial hair fibers are used for wigs, hairpieces, and doll hairs, the fineness, gloss, touch, texture, combing, good curl performance, etc. are the main required characteristics of quality. Of course, these properties are affected by the properties of the fiber itself, but it depends largely on the oil used. In particular, acrylic fiber occupies a major position in this field because of its human-like and animal-like texture. However, in conventional acrylic fibers, a polyether oil is generally used. When wet spinning of acrylic fibers, individual fibers are easily fused in the drying process, and the fiber separation property is low. There was a problem that it was inferior (in this case, good separation means that one fiber or one fiber is not fused and separated). If the splitting property is poor, the passage of the comb is bad or the hair is broken when it is passed through the comb. Therefore, the splitting property is one of the most important quality items of the fiber for artificial hair.
[0003]
In order to solve these problems, for example, a method has been proposed in which a matting agent such as cellulose acetate, aluminum hydroxide, aluminum oxide, magnesium oxide, and silicon oxide is added to the fiber. And the feeling of fiber roughness increases, and the combing property tends to deteriorate. In addition, the glossy artificial hair fibers that have become popular recently have had a problem that good splitting properties cannot be obtained because the amount of matting agent added cannot be increased. In addition, when a silicone-based oil is used alone, the splitting property is improved, but there is a problem that the fibers are too slippery and give an unnatural feel and curls are not collected. Thus, the present condition is that the acrylic artificial hair fiber which has the fiber performance for hairs which can satisfy all of fiber separation property, tactile sensation, combing property, curl performance, etc. has not been obtained.
[0004]
[Problems to be solved by the invention]
An object of the present invention is an acrylic artificial hair fiber that has significantly better separability than conventional acrylic artificial hair fibers, has excellent combing properties, and has a soft texture and natural luster with a sliminess. Is to provide.
[0005]
[Means for Solving the Problems]
As a result of diligent study, the inventors of the present invention generally paid attention to polyamine polyamide-based oils that are generally used as softening agents for acrylic fibers. It has been found that an acrylic artificial hair fiber having good and slimy soft feel can be obtained. The polyamine polyamide-based softener has a function of lowering a coefficient of friction between fibers, imparting sliminess to the feel of the fiber, and softening the fiber. However, the polyamine polyamide-based softener has a serious problem that when a plastic comb is used, hair is tangled at the tip of the fiber and the comb is difficult to pass. For this reason, as a result of further investigations, the present inventors have improved combability by using a silicone-based oil together, and also improved the fineness that was a drawback of acrylic artificial hair fibers, The present inventors have succeeded in developing an acrylic artificial hair fiber that is ideal as an artificial hair fiber, and have reached the present invention.
[0006]
As a result of intensive investigations on acrylic artificial hair fibers having good splitting properties, excellent combing, slimy soft touch and natural luster, polyamine polyamide softeners as oils Significantly improves the splitting properties, which are the disadvantages of thick denier acrylic wet-spun fibers, gives a soft and soft feel, and mixes the silicone oil with the polyamine polyamide softener. Thus, the present inventors have found that there is an effect of preventing combing property, in particular, tangling at the hair tips when passing through the comb, and the present invention has been completed.
[0007]
That is, the present invention relates to an emulsified dispersion obtained by adding 0.1 to 10% by weight of a silicone-based oil (B) to a solid content of an oil whose main component is a polyamine polyamide-based softening agent (A). It is a fiber for acrylic artificial hair formed by adhering in a solid content of 0.05 to 2.0% by weight with respect to the dry weight. The polyamine polyamide softener (A) is preferably at least one selected from the group consisting of compounds represented by the following formulas (I) to (XI) and / or salts thereof.

Further, the silicone oil (B) is at least one selected from the group consisting of dimethylpolysiloxane, methylhydridepolysiloxane, amino-modified silicone, epoxy-modified silicone, carboxylic acid-modified silicone, and polyether-modified silicone. More preferably.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail. The polyamine polyamide-based softening agent (A) used as an oil used for the acrylic artificial hair fiber of the present invention refers to a system of oils having both an amide group and an amino group in the molecule. Preference is given to at least one selected from the group consisting of compounds represented by formulas (I) to (XI) and / or their salts. These compounds may be in the form of, for example, acetate, glycolate, formate, hydrochloride, diethyl sulfate and the like. The polyamine polyamide softener (A) may be a single compound or a mixture of two or more.
[0009]
Next, the silicone-based oil agent (B) referred to in the present invention can be mixed with the cation type polyamine polyamide-based softening agent (A) and can be used without impairing the emulsifying dispersibility. For example, dimethylpolysiloxane , Methyl hydrogen polysiloxane, amino-modified silicone, epoxy-modified silicone, carboxylic acid-modified silicone, polyether-modified silicone, and the like. Of these, dimethylpolysiloxane and amino-modified silicone are more preferable from the viewpoint of the stability of the oil agent and the effect of improving the combability of the fiber. Moreover, the addition amount of a silicone type oil agent (B) is 0.1 to 10 weight% with respect to solid content of all the oil agents, More preferably, it is 0.3 to 5 weight%. When the addition amount is less than 0.1% by weight, the desired combing property tends to be not obtained. On the other hand, if it exceeds 10% by weight, it tends to be unsatisfactory as a fiber for artificial hair because it slips excessively.
[0010]
The amount of the oil agent applied to the synthetic fiber is preferably 0.05 to 2.0% by weight of the oil solid content with respect to the fiber dry weight. Is different. For example, when there are many minute irregularities on the fiber surface, preferably 0.1 to 1.8% by weight, more preferably 0.3 to 1.5% by weight, and when the fiber surface is relatively smooth, Preferably, it is 0.07 to 1.5 weight%, More preferably, it is 0.1 to 1.2 weight%. If the amount of oil agent attached is less than the above range, the desired soft tactile sensation cannot be obtained, and the effect of improving the combing property and separation property is insufficient, and static electricity is generated. On the other hand, if it exceeds the above range, the adhesive feeling of the tactile sensation increases, which is not preferable, and the problem of oil scale tends to occur in the production process.
[0011]
Furthermore, the oil agent used in the present invention may be a mixture with other types of oil agents other than the polyamine polyamide-based softener (A) and the silicone-based oil agent (B) as long as the effects of the present invention are not impaired. . For example, normal polyether (molecular weight 2000 to 15000) may be mixed in an oil solid content composition of 35% by weight or less in order to impart fiber convergence and moist texture, and to prevent generation of static electricity. However, if it exceeds 35% by weight, the stickiness and convergence of the fiber become excessively strong, which is not preferable as a fiber for artificial hair. Further, a surfactant necessary for improving the emulsifying dispersibility of the present oil agent can be added within a range not impairing the effects of the invention. Examples of the surfactant include the following formula (XII)

[0012]
As a method for applying the oil agent, a normal method can be adopted, but it is preferable to apply it to the swollen yarn after coagulation and washing with water. The swollen yarn spun by the wet spinning method is an undried yarn that has been solidified and washed with water, and has a number of pores in the fiber and a moisture content of 50 to 200% by weight or more. Article.
[0013]
The acrylic copolymer used in the acrylic artificial hair fiber referred to in the present invention contains 30 to 80% by weight of acrylonitrile, and contains at least one halogen-containing monomer typified by vinyl chloride or vinylidene chloride. Those containing ˜20% by weight, and other vinyl monomers copolymerizable therewith, such as sodium methallyl sulfonate, sodium allyl sulfonate, sodium styrene sulfonate, acrylic acid, vinyl acetate, methacrylic acid, A copolymer of acrylic acid alkyl ester and methacrylic acid alkyl ester may also be used.
[0014]
Furthermore, the single yarn fineness of the acrylic artificial hair fiber used in the present invention is preferably 10 to 100 denier, more preferably 15 to 70 denier. When the single yarn fineness exceeds 100 denier, it is not preferable because it is too hard as a fiber for hair. If the single yarn fineness is less than 10 denier, the doll hair having a relatively fine fineness is too soft, which is not preferable.
