Abstract

PROBLEM TO BE SOLVED: To provide a hair material for a toy, which is made of a core-sheath conjugated fiber having uniform thickness and good appearance.SOLUTION: A hair material for a toy is made of a core-sheath conjugated fiber comprising a core resin and a sheath resin. The core resin comprises a thermoplastic resin A, and a thermoplastic resin B having a chemical composition different from the thermoplastic resin A, and the thermoplastic resin B has a melt flow rate smaller than that of the thermoplastic resin A, and the amount of the thermoplastic resin B mixed is smaller than that of the thermoplastic resin A.

Description

本発明は玩具用毛髪に関する。詳細には、均一で見栄えが良い玩具用毛髪に関する。   The present invention relates to toy hair. More specifically, the present invention relates to toy hair that is uniform and looks good.

従来、玩具用毛髪として、単一の熱可塑性樹脂を用いて溶融紡糸によりマルチフィラメントを得ることが開示されている(例えば、特許文献1参照)。
しかしながら、単一の熱可塑性樹脂からなる毛髪は、適用する樹脂の溶融温度や粘度によっては製造工程で繊維同士の融着を生じて毛髪が得られ難くなる。これを具体的に説明すると、低融点の熱可塑性樹脂を用いる場合、該樹脂の固化温度が低いため、ノズルから紡出した後に冷却を行なうとしても、完全に固化する前にターンロールに達して繊維同士が融着して所望の毛髪が得られ難くなる。
そこで、芯鞘型複合繊維の鞘部に繊維同士の融着を生じ難い樹脂を適用することによって前記問題を解消することができるとしても、芯部の樹脂の選定によって繊維は太い箇所と細い箇所を有する不均一なものになることがあり、このような繊維は複数本を束ねたり、植毛した際、隣り合う繊維同士の太さが異なるため毛並みが揃っておらず、見栄えが悪く商品性に欠けたものとなる。
実開昭59−83932号公報
Conventionally, as toy hair, it has been disclosed to obtain a multifilament by melt spinning using a single thermoplastic resin (see, for example, Patent Document 1).
However, hair made of a single thermoplastic resin may cause fusion of fibers in the manufacturing process depending on the melting temperature and viscosity of the applied resin, making it difficult to obtain hair. Specifically, when using a thermoplastic resin having a low melting point, the solidification temperature of the resin is low, so even if cooling is performed after spinning from the nozzle, it reaches the turn roll before completely solidifying. The fibers are fused together, making it difficult to obtain the desired hair.
Therefore, even if the above problem can be solved by applying a resin that hardly causes fusion of fibers to the sheath part of the core-sheath type composite fiber, the fiber is selected from a thick part and a thin part by selecting the resin of the core part. When bundled or planted a plurality of such fibers, the adjacent fibers are different in thickness, so the fur line is not uniform, and the appearance is poor and the product quality is poor. It will be lacking.

本発明は、前述した玩具用毛髪の不具合を解消するものであって、繊維は太い箇所と細い箇所を有すことのない均一で見栄えの良い芯鞘型の複合繊維により形成された玩具用毛髪を提供しようとするものである。   The present invention eliminates the above-described problems of toy hair, and the toy hair is formed of a uniform and good-looking core-sheath type composite fiber that does not have thick and thin portions. Is to provide.

本発明は、芯部の樹脂と鞘部の樹脂とから構成される芯鞘型複合繊維により形成された玩具用毛髪であって、前記芯部の樹脂は、熱可塑性樹脂Aと、前記熱可塑性樹脂Aとは化学組成が異なる熱可塑性樹脂Bとを含んでなり、前記熱可塑性樹脂Bのメルトフローレートが熱可塑性樹脂Aよりも小さく、且つ、前記熱可塑性樹脂Bの配合量が熱可塑性樹脂Aよりも少ないことを特徴とする玩具用毛髪を要件とする。
更には、前記熱可塑性樹脂Bの融点が熱可塑性樹脂Aよりも高いこと、前記熱可塑性樹脂Aと熱可塑性樹脂Bは共にポリアミド系樹脂であること、前記芯部又は鞘部に可逆熱変色性材料又は光変色性材料を含有してなること等を要件とする。
The present invention relates to hair for toys formed by a core-sheath type composite fiber composed of a core resin and a sheath resin, wherein the core resin is thermoplastic resin A and the thermoplastic resin. The resin A includes a thermoplastic resin B having a different chemical composition, the melt flow rate of the thermoplastic resin B is smaller than that of the thermoplastic resin A, and the blending amount of the thermoplastic resin B is a thermoplastic resin. A toy hair characterized by being less than A is a requirement.
Further, the melting point of the thermoplastic resin B is higher than that of the thermoplastic resin A, the thermoplastic resin A and the thermoplastic resin B are both polyamide resins, and reversible thermochromic property in the core or sheath. It is required to contain a material or a photochromic material.

本発明は、繊維は太い箇所と細い箇所を有すことのない均一で見栄えの良い芯鞘型の複合繊維により形成された玩具用毛髪を提供できる。   INDUSTRIAL APPLICABILITY The present invention can provide toy hair formed of a core-sheath type composite fiber having a uniform and good appearance without having a thick portion and a thin portion.

本発明の玩具用毛髪を構成する芯部の樹脂は、熱可塑性樹脂Aと、前記熱可塑性樹脂Aとは化学組成が異なる熱可塑性樹脂Bとを併用してなる。
前記熱可塑性樹脂としては、ポリアミド樹脂、ポリエステル樹脂、ポリオレフィン樹脂等の熱可塑性樹脂が好適である。
前記ポリアミド樹脂としては、6ナイロン、6,6ナイロン、6,9ナイロン、610ナイロン、11ナイロン、12ナイロン、6−12共重合ナイロン、6,9−12共重合ナイロン、ポリアミドエラストマー等を例示できる。
前記ポリエステル樹脂としては、ポリヘキサメチレンテレフタレート、ポリエチレンテレフタレート、ポリブチレンテレフタレート、飽和脂肪族ポリエステル、ポリエステルエラストマー等を例示できる。
前記ポリオレフィン樹脂としては、低密度ポリエチレン、線状低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、ポリプロピレン−エチレンコポリマー、ポリイソブチレン、ポリブタジエン、エチレン−プロピレンラバー等を例示できる。
前記熱可塑性樹脂のうち、熱可塑性樹脂Aと熱可塑性樹脂Bとを選定して用いるうえで、前記熱可塑性樹脂Bのメルトフローレート(MFR)は熱可塑性樹脂Aよりも小さく、前記熱可塑性樹脂Bの配合量は熱可塑性樹脂Aよりも少なく配合する。
これによって化学組成が異なる熱可塑性樹脂同士を混合して押出成形した際に、生じる押出量が一定せず繊維の寸法が不規則になったり、あるいは規則的に変動するサージングを防止することができる。
繊維の溶融紡糸には、より均一な押出し性が求められるが、MFRの小さい熱可塑性樹脂B(溶融粘度の高い樹脂)の配合量を熱可塑性樹脂Aよりも少なくすることにより、均一に押出しが可能なことを見出した。
なお、MFRの小さい熱可塑性樹脂B(溶融粘度の高い樹脂)の融点が熱可塑性樹脂Aの融点よりも高いと、より安定に押出しが可能となり、繊維の均一性が向上する。
この挙動は熱可塑性樹脂AとBが共にポリアミド系樹脂の場合に顕著であった。
通常、溶融紡糸は樹脂の融点より30℃程度高い温度で行なわれるが、前述のMFRを満たす熱可塑性樹脂AとBを用いると、MFRの小さい樹脂の配合量が少ないため、融点が高くても溶融し易くなり、通常より低い設定温度で溶融紡糸が可能になる。
前記熱可塑性樹脂Aは、繊維を形成する樹脂全量中50質量%以上、好ましくは60質量%以上、より好ましくは70質量%以上配合される。
なお、前記二種類の熱可塑性樹脂A、Bとは別の樹脂を併用して用いることもできるが、前述した不均一な繊維を形成することが無いようにするため、繊維中に10質量%以下の範疇で添加することが好ましい。
The resin of the core part constituting the hair for toy of the present invention is formed by using the thermoplastic resin A and the thermoplastic resin B having a different chemical composition from the thermoplastic resin A in combination.
As the thermoplastic resin, a thermoplastic resin such as a polyamide resin, a polyester resin, or a polyolefin resin is suitable.
Examples of the polyamide resin include 6 nylon, 6,6 nylon, 6,9 nylon, 610 nylon, 11 nylon, 12 nylon, 6-12 copolymer nylon, 6,9-12 copolymer nylon, and polyamide elastomer. .
Examples of the polyester resin include polyhexamethylene terephthalate, polyethylene terephthalate, polybutylene terephthalate, saturated aliphatic polyester, and polyester elastomer.
Examples of the polyolefin resin include low density polyethylene, linear low density polyethylene, high density polyethylene, polypropylene, polypropylene-ethylene copolymer, polyisobutylene, polybutadiene, and ethylene-propylene rubber.
Among the thermoplastic resins, when the thermoplastic resin A and the thermoplastic resin B are selected and used, the melt flow rate (MFR) of the thermoplastic resin B is smaller than that of the thermoplastic resin A, and the thermoplastic resin The blending amount of B is less than that of the thermoplastic resin A.
As a result, when the thermoplastic resins having different chemical compositions are mixed and extruded, the generated extrusion amount is not constant, and the fiber size becomes irregular or the surging that regularly fluctuates can be prevented. .
Fiber melt spinning requires a more uniform extrudability, but by making the blending amount of thermoplastic resin B (resin with high melt viscosity) with a small MFR smaller than that of thermoplastic resin A, uniform extrusion is possible. I found it possible.
In addition, when the melting point of the thermoplastic resin B (resin having a high melt viscosity) having a low MFR is higher than the melting point of the thermoplastic resin A, it becomes possible to extrude more stably and the uniformity of the fibers is improved.
This behavior was remarkable when both the thermoplastic resins A and B were polyamide resins.
Usually, melt spinning is performed at a temperature about 30 ° C. higher than the melting point of the resin. However, when the thermoplastic resins A and B satisfying the MFR described above are used, the blending amount of the resin having a small MFR is small, so that the melting point is high. It becomes easy to melt and melt spinning is possible at a lower set temperature than usual.
The thermoplastic resin A is blended in an amount of 50% by mass or more, preferably 60% by mass or more, more preferably 70% by mass or more, based on the total amount of resin forming the fiber.
In addition, although it can also be used in combination with a resin different from the two types of thermoplastic resins A and B, in order to prevent the formation of the above-mentioned non-uniform fiber, 10% by mass in the fiber. It is preferable to add in the following categories.

本発明においては、芯部の樹脂を熱可塑性樹脂Aと、前記熱可塑性樹脂Aとは化学組成が異なる熱可塑性樹脂Bにより形成し、鞘部の樹脂を別の樹脂により構成することができる。

前記繊維(毛髪)は、太さが均一である他、光沢性に富む繊維を得ることができる。
繊維の外径は、30〜200μm、より好ましくは、40〜120μmの範囲であり、30μm未満の径のものは、細すぎて玩具用毛髪として適しておらず、一方、200μmを越えると太くなり過ぎて、毛髪の性状を示し難くなる。
The fibers (hairs) are uniform in thickness, and can provide fibers with high gloss.
The outer diameter of the fiber is in the range of 30 to 200 μm, more preferably in the range of 40 to 120 μm, and those having a diameter of less than 30 μm are too thin to be suitable as hair for toys, while on the other hand, the fiber becomes thicker when exceeding 200 μm. After that, it becomes difficult to show the properties of the hair.

前記玩具用毛髪の芯部又は鞘部には一般顔料、蛍光顔料、可逆熱変色性材料、光変色性材料(フォトクロミック材料)等を添加して種々の色調のフィラメントを得ることもできる。
前記可逆熱変色性材料は、電子供与性呈色性有機化合物と電子受容性化合物と呈色反応を可逆的に生起させる有機化合物媒体の三成分を含む可逆熱変色性組成物をマイクロカプセルに内包させた可逆熱変色性マイクロカプセル顔料が有効である。
前記可逆熱変色性マイクロカプセル顔料は粒子径1〜30μm、好ましくは3〜15μmの範囲のものを適用でき、樹脂中に0.5〜40質量%、好ましくは1〜30質量%含有させる。
0.5質量%未満の配合量では鮮明な熱変色効果を視覚させ難いし、40質量%を越えると過剰であり、消色状態にあって残色が生じることもある。
前記光変色性材料は、スピロオキサジン系化合物、スピロピラン系化合物、ジアリールエテン系化合物等のフォトクロミック化合物が有効である。
なお、前記フォトクロミック化合物はスチレン系オリゴマーに溶解して用いることが好ましく、色濃度を高くしたり、変色感度を調整することができる。
前記スチレン系オリゴマーは重量平均分子量が250乃至4000、好ましくは300乃至4000のものが用いられる。
なお、重量平均分子量は、GPC法(ゲル浸透クロマトグラフ法)により測定する。
前記スチレン系オリゴマーとしては、低分子量ポリスチレン、スチレン−α−メチルスチレン共重合体、α−メチルスチレン重合体、α−メチルスチレンとビニルトルエンの共重合体等が挙げられる。
前記光変色性材料は、マイクロカプセルに内包させた光変色性マイクロカプセル顔料として用いることもできる。
ここで、鞘部に耐熱性の低い可逆熱変色性組成物をマイクロカプセルに内包させた可逆熱変色性マイクロカプセル顔料等を含有させる場合は、鞘部に融点の低い樹脂を使用する必要があるが、紡糸温度が高いと鞘部の繊維同士が融着するため、温度を下げる必要がある。温度を下げた状態で紡糸するために芯部の樹脂が熱可塑性樹脂Aと、前記熱可塑性樹脂Aとは化学組成が異なる熱可塑性樹脂Bとを含んでなり、前記熱可塑性樹脂Bのメルトフローレートが熱可塑性樹脂Aよりも小さく、且つ、前記熱可塑性樹脂Bの配合量が熱可塑性樹脂Aよりも少ないことは重要な要件となる。
General pigments, fluorescent pigments, reversible thermochromic materials, photochromic materials (photochromic materials) and the like can be added to the toy hair core or sheath to obtain filaments of various colors.
The reversible thermochromic material includes a microcapsule containing a reversible thermochromic composition containing three components of an organic compound medium that reversibly causes a color reaction between an electron donating colorable organic compound and an electron accepting compound. Reversible thermochromic microcapsule pigments are effective.
The reversible thermochromic microcapsule pigment may have a particle diameter of 1 to 30 μm, preferably 3 to 15 μm, and is contained in the resin in an amount of 0.5 to 40% by mass, preferably 1 to 30% by mass.
When the blending amount is less than 0.5% by mass, it is difficult to visually recognize a vivid thermochromic effect. When the blending amount exceeds 40% by mass, the amount is excessive, and a residual color may be generated in a decolored state.
Photochromic compounds such as spirooxazine compounds, spiropyran compounds, and diarylethene compounds are effective as the photochromic material.
The photochromic compound is preferably used by dissolving in a styrene-based oligomer, and the color density can be increased or the color change sensitivity can be adjusted.
The styrene oligomer has a weight average molecular weight of 250 to 4000, preferably 300 to 4000.
The weight average molecular weight is measured by GPC method (gel permeation chromatography).
Examples of the styrene oligomer include low molecular weight polystyrene, styrene-α-methylstyrene copolymer, α-methylstyrene polymer, α-methylstyrene and vinyltoluene copolymer, and the like.
The photochromic material can also be used as a photochromic microcapsule pigment encapsulated in microcapsules.
Here, when a reversible thermochromic microcapsule pigment in which a reversible thermochromic composition having low heat resistance is encapsulated in microcapsules is contained in the sheath, it is necessary to use a resin having a low melting point in the sheath. However, if the spinning temperature is high, the fibers in the sheath part are fused together, so the temperature needs to be lowered. In order to perform spinning at a reduced temperature, the core resin comprises a thermoplastic resin A and a thermoplastic resin B having a different chemical composition from the thermoplastic resin A, and the melt flow of the thermoplastic resin B It is an important requirement that the rate is smaller than that of the thermoplastic resin A and the amount of the thermoplastic resin B is less than that of the thermoplastic resin A.

更に、汎用の各種可塑剤、例えば、フタル酸系、脂肪族二塩基酸エステル系、リン酸エステル系、エポキシ系、フェノール系、トリメリット酸系等を配合して柔軟性を付与したり、加工性、物性等を改善するために、炭酸カルシウム、炭酸マグネシウム、酸化チタン、タルク等を添加することもできる。   Furthermore, general-purpose plasticizers such as phthalic acid, aliphatic dibasic acid ester, phosphoric acid ester, epoxy, phenol, trimellitic acid, etc. In order to improve the properties and physical properties, calcium carbonate, magnesium carbonate, titanium oxide, talc and the like can be added.
