Description
この発明は、筆記や描画の際に用いられる化粧用の塗布具に関するものである。
より具体的には、化粧品用の塗布具に関するものであって、それらの製造技術に関するものである。
The present invention relates to a cosmetic applicator used for writing and drawing.
More specifically, the present invention relates to a cosmetic applicator, and relates to a manufacturing technique thereof.
化粧用の塗布具を始めとして、筆記や描画の分野で、種々の塗布具が幅広く使用されている。
これら種々の塗布具については、それぞれ品質の良いものを求めて材質や形状、さらには、その製法についての検討が、常に行われている。
Various applicators are widely used in the fields of writing and drawing, including cosmetic applicators.
About these various applicators, the quality and the quality of each of these applicators and the production method thereof are constantly being investigated in order to obtain high quality products.
かかる塗布具の製造方法としては、例えば、獣毛や合成繊維などを束ねて、筆又はブラシとする方法がある。
また、接着剤で結合した繊維束の先端を、尖鋭形状に研削加工して塗布部材とする方法や、合成樹脂製の多孔質スポンジ状材料を、穂先とする成形品を塗布部材とする方法、さらには、内部にスリット状の毛細管を形成した弾性又は軟質の熱可塑性合成樹脂の押出成形品を、塗布部材とする方法などがある。
As a method for producing such an applicator, for example, there is a method of bundling animal hair or synthetic fiber to form a brush or a brush.
Also, the method of grinding the tip of the fiber bundle bound with the adhesive into a sharp shape to make an application member, and the method using a porous sponge-like material made of synthetic resin as the tip of the molded article, Furthermore, there is a method of using an extruded product of an elastic or soft thermoplastic synthetic resin in which slit-like capillaries are formed inside as an application member.
これらの製法の中でも、接着剤で結合した毛細管力を有する繊維束の先端を、尖鋭形状に研削加工して塗布体（以下、「繊維束芯」とも言う。）とする方法が、特公昭５３−１６７３６号公報（特許文献１）において提案されている。
この方法は、塗布幅のバラツキが少なく、塗布液の流れが均一で、安定した品質の塗布体を多品種、大量に供給することを可能にする方法として、普及している。
しかも、この方法によれば、極めて僅かな樹脂分をほぼ均一に附着させると、先端の非常にしなやかなものとなり、このような繊維束芯はアイライナ用の塗布具としてとして使われることが示されている。
Among these production methods, the method of grinding the tip of a fiber bundle having a capillary force bonded with an adhesive into a sharp shape to form an applied body (hereinafter also referred to as “fiber bundle core”) is disclosed in JP-B-53. -16736 (Patent Document 1).
This method is widely used as a method that allows a wide variety and a large amount of coated bodies with a stable quality with a small coating width variation and uniform coating liquid flow.
Moreover, according to this method, when a very small amount of resin is applied almost uniformly, the tip becomes very supple, and such a fiber bundle core is used as an applicator for an eyeliner. ing.
前記の繊維束芯は、本質的に接着剤で固結されたものであるので硬質であった。
柔らかい感触の塗布体を得るには、ペン芯の材料となる棒状物を後加工で、ある程度研磨加工に耐える程度に強度を持たせる必要があった。
すなわち、ある程度硬い棒状物とする必要があり、後加工によって棒状物の一端を鋭角のテーパー状とすることで、始めてその先端がしなやかになるというものであった。
また、この方法では、棒状物を形成し、切断・研磨という後加工を必要とするものであるので、特に柔らかい化粧用の棒状物は、加工し難いといった欠点があった。
さらに、しなやかな棒状物を研磨加工しようとすると、形状を整形する際に、加工によって繊維がバラケてしまうという問題を有するので、柔軟な繊維束芯からなる塗布具の製法には、必ずしも適したものではない。
The fiber bundle core was hard because it was essentially consolidated with an adhesive.
In order to obtain an application body with a soft feel, it was necessary to give the rod-like material, which is a material for the pen core, sufficient strength to withstand a certain degree of polishing by post-processing.
In other words, it is necessary to make the rod-like object hard to some extent, and the tip of the rod-like object is made to be supple for the first time by making one end of the rod-like object into an acute taper shape by post-processing.
In addition, this method requires a post-processing such as cutting and polishing after forming a bar-like material, and thus has a drawback that it is difficult to process a particularly soft cosmetic bar-like material.
Furthermore, when trying to polish a pliable rod-shaped object, there is a problem that fibers are broken by processing when shaping the shape, so it is not necessarily suitable for a method of manufacturing an applicator made of a flexible fiber bundle core. It is not a thing.
そのため、柔らかい繊維束芯を得る方法が、種々提案されてきている。
例えば、実公平０１−１１５０４号公報（特許文献２）には、核成分としての、単糸繊度が７デニールを超えない極細巻縮ナイロン繊維と、不定形要素を形成する合成樹脂エラストマとからなる、ゴム状の弾力性、柔軟性および復元性を有することを特徴とする繊維束芯を用いることが提案されている。
Therefore, various methods for obtaining a soft fiber bundle core have been proposed.
For example, Japanese Utility Model Publication No. 01-11504 (Patent Document 2) is composed of an ultra-fine wound nylon fiber having a single yarn fineness not exceeding 7 deniers as a core component and a synthetic resin elastomer forming an amorphous element. It has been proposed to use a fiber bundle core characterized by having rubber-like elasticity, flexibility and resilience.
さらに、特許第４５３５２２４号公報（特許文献３）では、化粧用塗布具とするための柔らかい感触を与える繊維束芯を、繊維束芯内における接着剤量を意図的に偏在させることによって、使用の際の僅かな応力で繊維束が解れる中心部、すなわち、接着剤量の少ない中心部をもった繊維束芯を得ることにより製造することが開示されている。 Furthermore, in Japanese Patent No. 4535224 (Patent Document 3), a fiber bundle core that gives a soft feel for a cosmetic applicator is used by intentionally unevenly distributing the amount of adhesive in the fiber bundle core. It is disclosed to manufacture by obtaining a fiber bundle core having a center part where the fiber bundle is unwound by a slight stress, that is, a center part having a small amount of adhesive.
一方、化粧品関連の塗布具として、形状が偏平体の塗布体を用いることが、特開昭５９−１３４７０９号公報（特許文献４）、特開昭５７−６４６０７号公報（特許文献５）等に開示されている。
また、市場においても、そのような形状の塗布体を有する塗布具が要望されている。
On the other hand, as a cosmetic-related applicator, use of an applicator having a flat shape is disclosed in JP-A-59-134709 (Patent Document 4), JP-A-57-64607 (Patent Document 5) and the like. It is disclosed.
Moreover, the applicator which has the application body of such a shape is also demanded in the market.
この発明はかかる現状に鑑み、塗布体、特にアイライナやアイブロなどの化粧用としての塗布具として要望されている、偏平状の塗布体であって、しかも柔軟性を有する塗布体を、均一な品質で、工業的に有利な方法で調製する方法を提供すべく検討を行った。 In view of the present situation, the present invention is a flat-shaped application body that is required as an application body for makeup, such as an eyeliner and eyebrows, and has a uniform quality. The present inventors have studied to provide a method of preparing by an industrially advantageous method.
その際に、当然のことであるが、引用文献１，２に示される先端を尖鋭形状とか、たがね形状等に研磨する必要がないこと、柔軟性を持たせることによって生ずる撓みによっても、加工が均一に行えること、鋭角な形状の確保ができること、品質にバラツキが生じないこと、塗布面もしくは筆記面の表面が滑らかであること、さらには、加工による材料の損失等を可及的に抑えることが可能な塗布体を調製方法の検討を行った。 At that time, as a matter of course, it is not necessary to polish the tip shown in the cited documents 1 and 2 into a sharp shape, a chisel shape, etc., also due to bending caused by giving flexibility, Processing can be performed uniformly, sharp shape can be ensured, quality does not vary, the surface of application or writing surface is smooth, and material loss due to processing is as much as possible. The preparation method of the coated body that can be suppressed was examined.
さらに、柔らかい塗布体は、そのまま使うと折れ曲がり易く、塗布し難いという問題が惹起されたとしても、前記課題を避けるために、塗布具から突出させる塗布体の突出長さを短くし、実質的に塗布面（サイド）が少なくなって、使用範囲が狭くなるといった問題や、塗布面が狭いことから塗布具の先端部分が肌に接触してしまい、塗布し難いといった問題も併せて解決すべく検討を行った。 Furthermore, even if the problem arises that the soft applicator tends to bend and is difficult to apply if used as it is, the projecting length of the applicator projecting from the applicator is shortened in order to avoid the above problem. Study to solve the problem that the application surface (side) is reduced and the range of use is narrowed, and that the tip of the applicator comes into contact with the skin because the application surface is narrow, making it difficult to apply. Went.
その結果、繊維束芯の製造において、原料の繊維としてナイロン繊維を用いること、前記ナイロン繊維束を、特定の断面形状からなる空孔を有し、かつ全体を扁平状に成型できる異形のダイを使用して加熱圧縮すること等によって、前記課題を解決できることを見出し、この発明を完成させたものである。
As a result, in the production of the fiber bundle core, using a nylon fiber as a raw material fiber, the nylon fiber bundle has a hole having a specific cross-sectional shape, and a deformed die that can be molded into a flat shape as a whole. The present invention has been completed by finding that the above-mentioned problems can be solved by, for example, heating and compressing.

The material for an applied body can be easily and easily manufactured at low cost.
In the case of cosmetics, since it is used on the skin, a soft writing feeling is obtained, and the porosity of the cosmetic liquid is preferably 60 to 85%.
この発明にかかる塗布体は、得ようとする塗布体の用途に応じて、あらかじめ長辺と短辺の比率の選定、気孔率や圧縮試験による耐折曲げ強度を適切に選択することによって、化粧用ないし筆記用に最適のものとすることができる。
なお、この発明においては、長辺と短辺との比率として２０〜２：１、かつ厚みとして０．５〜１．８ｍｍを選択し、長さ６ｍｍにおける、傾斜２０°の圧縮板での圧縮試験による耐折曲げ強度として５〜１０４．５ｇを選択するので、化粧用に最適である。
The coated body according to the present invention can be made by appropriately selecting the ratio of the long side and the short side, and appropriately selecting the bending strength according to the porosity and the compression test in accordance with the application of the coated body to be obtained. It can be optimized for use or writing.
In the present invention, the ratio of the long side to the short side is selected from 20 to 2: 1, the thickness is selected from 0.5 to 1.8 mm, and the compression is performed with a compression plate having an inclination of 20 ° at a length of 6 mm. Since 5 to 104.5 g is selected as the bending strength by the test, it is optimal for cosmetic use.
この発明にかかる塗布具は、前記特質を有する塗布体を使用しているので、特に化粧用具として使用する場合には、使用する塗布体が柔らかな質感のため、肌に使用しても痛くならず快適な肌触り感を得られる。
また、非常に柔らかく肌触りのよい化粧用塗布体として使用する場合や、筆記用などある程度の押圧力を要する場合には、塗布体全体が湾曲ないし折れ曲るおそれもあるので、かかる場合には、塗布体の幅広面に沿って所要長さの支持部材を近接させて配置することによって、塗布面（サイド）部分を残しつつ、湾曲ないし折曲がりを防止することができる。
Since the applicator according to the present invention uses an applicator having the above characteristics, the applicator to be used is particularly soft when used as a cosmetic tool, so that even if used on the skin, it hurts. A comfortable feel can be obtained.
In addition, when used as a cosmetic application body that is very soft and soft to the touch, or when a certain pressing force is required, such as for writing, the entire application body may be bent or bent. By arranging a support member of a required length close to the wide surface of the application body, it is possible to prevent bending or bending while leaving the application surface (side) portion.
この発明の塗布体用素材の製造方法及び塗布体用素材並びに塗布体及び塗布具は、従来の繊維束芯の製造方法を基本とするものである。
前記繊維束芯の原材料としては、ナイロン繊維を使用するものである。
以下、その点を主体として、この発明をより具体的に説明する。
The manufacturing method of the applied body material, the applied body material, the applied body, and the applicator of the present invention are based on the conventional manufacturing method of the fiber bundle core.
As the raw material of the fiber bundle core, nylon fiber is used.
Hereinafter, the present invention will be described more specifically with this point as a main component.
繊維束芯の製造方法は、特許文献１あるいは３に示されるように、連続する多数の繊維を巻き取ったボビン、テンション調整用の送りロール、多数の繊維を加熱して束状にするためのパイプ状ダイを有する加熱ブロック、束状に形成された繊維束に樹脂を含浸させるための樹脂溶液槽、繊維束に含浸した樹脂を硬化させるための熱風乾燥炉、引き取りローラから引き取られる樹脂硬化した繊維束を、所要の長さに切断するためのカッターから構成される製造装置を使用して行うものである。 As shown in Patent Document 1 or 3, the manufacturing method of the fiber bundle core is a bobbin wound up with a large number of continuous fibers, a feed roll for tension adjustment, and for heating a large number of fibers into a bundle shape. A heating block having a pipe-shaped die, a resin solution tank for impregnating a bundle of fiber bundles with a resin, a hot air drying furnace for curing the resin impregnated into the bundle of fibers, and a resin cured from a take-up roller This is performed using a manufacturing apparatus including a cutter for cutting a fiber bundle into a required length.
この発明においては、長手方向に引き揃えたナイロン繊維束を、ボビンから繰り出して送りロールによってテンション調整しながらパイプ状の異形ダイに供給する際、前記ナイロン繊維束をあらかじめ一定の形状に整形し、品質の安定した製品としている。
具体的には、得ようとする最終製品、すなわち、所望の断面形状を有する塗布体の断面形状に対応し、かつ当該断面形状よりも拡大した形状の空孔を有するガイドの空孔を通過させ、ナイロン繊維束を所望の形状に整形する。
In this invention, when the nylon fiber bundle aligned in the longitudinal direction is fed from the bobbin and supplied to the pipe-shaped deformed die while adjusting the tension by the feed roll, the nylon fiber bundle is shaped into a certain shape in advance, The product is stable in quality.
Specifically, it passes through the hole of the guide having the hole corresponding to the cross-sectional shape of the final product to be obtained, that is, the applied body having the desired cross-sectional shape and having a shape larger than the cross-sectional shape. The nylon fiber bundle is shaped into a desired shape.
前記ガイドに設けられる空孔は、最終製品の断面形状に対応し、かつ当該断面形状よりも拡大した形状を有するものであるが、必ずしも最終製品（塗布体）の断面形状に正確に比例する必要はない。
むしろ、次の工程のダイにおける加熱・圧縮成形においての、各方向からの圧縮力の差異に基づいて調整することが望ましい。
The holes provided in the guide correspond to the cross-sectional shape of the final product and have a shape larger than the cross-sectional shape. However, the holes need not necessarily be proportional to the cross-sectional shape of the final product (applied body). There is no.
Rather, it is desirable to adjust based on the difference in compression force from each direction in the heating and compression molding in the die of the next step.
この発明においては、得ようとする塗布体素材が扁平であるため、前記ガイドによってナイロン繊維束をあらかじめ整形しておかないと、次工程であるダイによる所望形状への加熱圧縮成型の際に、中央部に繊維が多く、両端にナイロン繊維が少なく偏在してしまうことがある。
したがって、あらかじめナイロン繊維束を、所望断面形状に整形しておくことで、安定した塗布体素材の製造が行ない易くなる。
In this invention, since the applied body material to be obtained is flat, if the nylon fiber bundle is not pre-shaped by the guide, in the heat compression molding to the desired shape by the die that is the next step, There are cases where there are many fibers at the center and few nylon fibers at both ends.
Therefore, by shaping the nylon fiber bundle into a desired cross-sectional shape in advance, it becomes easy to manufacture a stable coated body material.
例えば、得ようとする塗布体の断面が、長軸方向の長さと短軸方向の長さが３．１ｍｍ×０．９ｍｍの扁平な角丸長方形の場合、前記ガイドに設けられる空孔は、長軸方向の長さと短軸方向の長さが２０ｍｍ×５ｍｍの偏平状の長方形の断面構造を有するものを使用する。 For example, when the cross section of the application body to be obtained is a flat rounded rectangle with a length in the major axis direction and a length in the minor axis direction of 3.1 mm × 0.9 mm, the holes provided in the guide are: Those having a flat rectangular cross-sectional structure with a length in the major axis direction and a length in the minor axis direction of 20 mm × 5 mm are used.
この発明に適用される最も好ましい繊維は、ナイロン繊維である。
ポリエステル繊維の場合は、特に高い気孔率を有する繊維束芯は繰り返し使うと、繊維間を接着している樹脂が剥がれて、バラける傾向が認められる。
The most preferred fiber applied to this invention is nylon fiber.
In the case of polyester fibers, when a fiber bundle core having a particularly high porosity is repeatedly used, the resin bonding between the fibers is peeled off and a tendency to be broken is recognized.
ナイロン繊維束の製造装置としては、公知のものを適用することができる。
使用するダイの材質、ダイによる加熱条件、塗布される熱硬化性樹脂、樹脂溶液の濃度、乾燥炉による乾燥条件等も公知の条件が適用されるが、熱硬化性樹脂として、この発明にとり好ましいものは、イソシアネートとポリオールからなるウレタン系樹脂である。
As a nylon fiber bundle manufacturing apparatus, a known apparatus can be applied.
Known conditions apply to the material of the die to be used, the heating conditions by the die, the thermosetting resin to be applied, the concentration of the resin solution, the drying conditions by the drying furnace, etc., but preferred as the thermosetting resin for this invention A thing is urethane type resin which consists of an isocyanate and a polyol.
ダイによる加熱条件や乾燥炉の温度としては、温度１７０〜２１５℃の温度の範囲がダイによる加熱条件である。
乾燥炉の温度は、通常、温度４０〜２５０℃の範囲で、樹脂溶液に用いられる溶剤の種類や樹脂の濃度により、適宜調整される。
As the heating conditions by the die and the temperature of the drying furnace, the temperature range of 170 to 215 ° C. is the heating conditions by the die.
The temperature of the drying furnace is usually appropriately adjusted in the temperature range of 40 to 250 ° C. according to the type of solvent used in the resin solution and the concentration of the resin.
なお、得られるナイロン繊維集束体による塗布体素材の柔らかさや使用感、さらにはマニキュアなどの塗布料の流出量や保持力などは、繊維の径、繊維の種類と量、合成樹脂の種類とナイロン繊維集束体を接着固定する樹脂量、切削部の長さ、厚さなどにより自由に調節することが可能である。
その際、塗布体用素材とするためには、ナイロン繊維集束体の気孔率が３５〜８５％であることが好ましい。
In addition, the softness and feeling of use of the coated material by the obtained nylon fiber bundling body, as well as the outflow amount and holding power of coating materials such as nail polish, fiber diameter, fiber type and amount, synthetic resin type and nylon The fiber bundling body can be freely adjusted according to the amount of resin to be bonded and fixed, the length and thickness of the cutting part, and the like.
In that case, in order to make it the raw material for application bodies, it is preferable that the porosity of a nylon fiber focusing body is 35 to 85%.
この気孔率が３５％より低くなると、マニキュアなどの塗布液の流出量が減少してカスレが生じ易く、塗布線の色が薄くなるおそれがある。
また、気孔率が８５％より高くなると、構造体の部分が少ないので、形状維持が難しく、形状が不安定になるおそれがある。
When this porosity is lower than 35%, the amount of the coating liquid such as nail polish that flows out tends to be reduced and the coating line is likely to be light.
On the other hand, when the porosity is higher than 85%, there are few structural parts, so that it is difficult to maintain the shape and the shape may become unstable.
特に、化粧用途に用いる場合は、肌に使用するため、軟らかい筆記感が得られ、化粧液の通りがよい６０〜８５％の気孔率であることがより好ましい。
気孔率が６０％より気孔率が低いと、肌に触れた際の感触が硬くなり、粘調な場合が多いメイクアップ用の化粧液の通りが悪くなり易く、十分なフローが得られず、結果としてカスレが生じ易くなる。
なお、ナイロン繊維束の気孔率は、用いられる原料繊維（ナイロン）の総量ないしは合成樹脂の樹脂量により制御される。
In particular, when used in cosmetic applications, since it is used on the skin, a soft writing feeling is obtained, and the porosity of the cosmetic liquid is preferably 60 to 85%.
If the porosity is lower than 60%, the feel when touching the skin becomes hard, the makeup liquid for makeup, which is often viscous, tends to deteriorate, and a sufficient flow cannot be obtained. As a result, blurring tends to occur.
The porosity of the nylon fiber bundle is controlled by the total amount of raw material fibers (nylon) used or the resin amount of the synthetic resin.
かくして得られるナイロン繊維集束体は、塗布体用素材１となるものである。
このナイロン繊維集束体は、所望の断面形状を有した長尺体である。
具体的には、図１に示すような、断面形状が少なくとも横長楕円形ないしは角丸長方形（図１の（ａ））、長方形（同（ｂ））、底辺が長く、高さの低い変形三角形（同（ｄ））もしくは側面視水滴状）同（ｅ））のものが好ましいが、扁平なものであれば前記形状に特定されるものではない。
なお、同（ｃ）に示す塗布体用素材１は、断面が長方形のナイロン繊維集束体の四隅を長手方向に沿って弧状に面取りしたものである。
The nylon fiber bundle obtained in this way is the material 1 for the applied body.
The nylon fiber collecting body, Ru elongate body der having a desired cross-sectional shape.
Specifically, as shown in FIG. 1, a deformed triangle having a cross-sectional shape of at least a horizontally long ellipse or a rounded rectangle (FIG. 1A), a rectangle (FIG. 1B), a long base, and a low height. ((D)) or water droplets in side view) (e)) is preferable, but the shape is not specified as long as it is flat.
In addition, the material 1 for application bodies shown to the same (c) is what chamfered in the arc shape along the longitudinal direction at the four corners of the nylon fiber focusing body with a rectangular cross section.
前記塗布体用素材の厚みは、０．５〜２．０ｍｍ、より好ましくは０．５〜１．８ｍｍ、さらに好ましくは０．５〜１．５ｍｍのものであって、この範囲内の厚みとすることで、肌への使用時に痛みを与えることがなく、なおかつ適度な弾力を有し、繰り返しの使用に耐えるものとなる。
得られた長尺体の厚みが２．０ｍｍを超えるものは、肌に触れた場合硬く感じるため好ましくなく、０，５ｍｍ以下のものは、塗布体がペラペラのものになり、実用上の強度が得られ難く、使用に耐えられない。
The thickness of the material for the application body is 0.5 to 2.0 mm, more preferably 0.5 to 1.8 mm , and still more preferably 0.5 to 1.5 mm , and the thickness is within this range. By doing so, there is no pain at the time of use on the skin, and it has an appropriate elasticity and can withstand repeated use.
When the thickness of the obtained elongated body exceeds 2.0 mm, it is not preferable because it feels hard when touching the skin, and when the thickness is 0.5 mm or less, the coated body is a tangled one, and the practical strength is low. It is difficult to obtain and cannot be used.
前記塗布体用素材は、長辺の幅が１．５〜３０ｍｍで、短辺の幅が０．５〜２．０ｍｍ、好ましくは０．５〜１．８ｍｍのものであって、その比が２０〜２：１の範囲内のものである。
長辺の幅が３０ｍｍを超えるものは、塗布部が大きくなりすぎて化粧など細かい作業には不向きとなる。
１．５ｍｍ以下のものは、細いので強度が弱くなって使用時に折れ曲がり易く、強度を維持するための支持機構も備え難い。
また、全体が細くなるので、長辺と短辺の異なる線幅の使い分けができるという、この発明の利点が発揮し難くなり、好ましくない。
短辺の幅が２．０ｍｍを超えるものは、使用感が硬くなってくるので、肌への使用時に痛みを与えることがある。
０．５ｍｍ以下のものは、ペラペラで強度が保ちづらく、使用時に折れ曲がり易いので好ましくない。
The coated body material has a long side width of 1.5 to 30 mm and a short side width of 0.5 to 2.0 mm , preferably 0.5 to 1.8 mm , and the ratio is It is within the range of 20-2: 1.
When the width of the long side exceeds 30 mm, the application part becomes too large and is unsuitable for fine work such as makeup.
Those having a thickness of 1.5 mm or less are so thin that the strength is weak and they are easily bent during use, and it is difficult to provide a support mechanism for maintaining the strength.
Moreover, since the whole becomes thin, the advantage of the present invention that it is possible to selectively use different line widths of the long side and the short side is difficult to be exhibited, which is not preferable.
That the width of the short side is more than 2.0mm, since the feeling of use becomes hard, there is possible to give a pain at the time of use to the skin.
Those having a thickness of 0.5 mm or less are not preferable because the strength is difficult to maintain with a slick surface and they are easily bent during use.
この発明においては、塗布体用素材１の条件は、厚みが０．５〜１．８ｍｍで、長辺と短辺の幅の比率が２０〜２：１で、かつ断面形状が、少なくとも横長楕円形ないし角丸長方形、長方形、変形三角形もしくは側面視水滴状のものであることを必須とするものである。
その際、短辺に対して長辺を２０〜２倍とすることによって、短辺の側を使用すれば細い線が、長辺の側を使用すれば太い線を簡単に描くことができ、前記に記載した効果と併せて、使い勝手が非常によく、かつ見た目もスマートな塗布体用素材となる。
In the present invention, the condition of the material 1 for an applied body is that the thickness is 0.5 to 1.8 mm, the ratio of the width of the long side to the short side is 20 to 2: 1, and the cross-sectional shape is at least horizontally long. It is essential to have an elliptical shape, a rounded rectangular shape, a rectangular shape, a deformed triangular shape, or a side-viewed water droplet shape.
At that time, by making the long side 20 to 2 times the short side, if the short side is used, a thin line can be easily drawn, and if the long side is used, a thick line can be easily drawn. In combination with the effects described above, the material for the applied body is very easy to use and looks smart.
長尺体のナイロン繊維集束体からなる塗布体用素材１は、任意の長さにカットして塗布具用の塗布体２とされる。 An applicator material 1 made of a long nylon fiber bundle is cut into an arbitrary length to form an applicator application body 2.
塗布体用素材１をカットして得られた塗布体２の先端は、通常、図２（ａ），図２（ｂ）に示されるようなカットにより生じる単純な形状で用いられる。
その際、用途に応じて、図２（ｃ）〜図２（ｈ）のような形状にすることも、塗布体用素材１の単なる切断もしくは打ち抜き加工により形成することができる。
また、研削加工などを必要としなくても、十分に塗布体として使用することができる。 なお、先端部には、目的に応じて所望の加工を施すことも、当然のことながら可能なものである。
The tip of the application body 2 obtained by cutting the material for application body 1 is usually used in a simple shape generated by the cutting as shown in FIGS. 2 (a) and 2 (b).
In that case, according to a use, it can also form in the shape like FIG.2 (c)-FIG.2 (h) by the simple cutting | disconnection or stamping of the raw material 1 for application bodies.
Moreover, even if grinding is not required, it can be sufficiently used as an applied body. Needless to say, the tip portion can be subjected to desired processing according to the purpose.
前記塗布体２は、図３に示されるように、通常の方法で、塗布液を含有する中綿３を有する塗布具本体４に取り付けられ、塗布具の筆記部又は塗布部として用いられる。
その際、図８に示すように、断面が長方形（矩形状）の塗布体２を、全体を湾曲させて折れ防止加工を施した塗布体２ａとすることもできる。
さらに、図示しないが、厚みの薄い塗布体２にあっては、複数枚を面方向において積層して筆記部又は塗布部とすることもできる。
As shown in FIG. 3, the applicator 2 is attached to an applicator main body 4 having a batting 3 containing a coating liquid by a normal method, and is used as a writing part or an applicator of the applicator.
In that case, as shown in FIG. 8, the application body 2 having a rectangular cross section (rectangular shape) can be formed into an application body 2a that is curved as a whole and subjected to a break prevention process.
Furthermore, although not illustrated, in the thin application body 2, a plurality of sheets can be laminated in the surface direction to form a writing part or an application part.
＜実施例１＞
繊維の太さが２デシテックス（Ｄｅｃｉ Ｔｅｘ又はｄｔｅｘ）のナイロン繊維を、総量が４，０００ｄｔｅｘになるように、テンション調整しながら集束させてボビンに巻き取った。
そのボビンからナイロン繊維束を引き出し、内寸が長辺２０ｍｍ、短辺５ｍｍの長方形状の空孔を有するガイドの中にナイロン繊維束を引き通し、ナイロン繊維束を扁平な形状に整える。
引き続き、扁平化されたナイロン繊維束を、内寸が長辺３．１ｍｍ、短辺０．９ｍｍの両末端に円弧を有する長方形状の空孔を有するパイプ状のダイ中に引き通し、加熱圧縮成形し、長辺３．１ｍｍ、短辺０．９ｍｍの角丸長方形状のナイロン繊維集束体に仕上げたのち、下記組成の樹脂溶液を収納した樹脂溶液槽内を、オリフィスを介して通過させる。
（樹脂溶液組成）
ウレタン樹脂（イソシアネート＋ポリオール） ６質量％
メチレンクロライド ９４質量％
角丸長方形状を有する樹脂溶液を含浸したナイロン繊維集束体を、温度１３０〜１４０℃に設定した熱風乾燥炉を通過せしめて、溶剤を除去し、樹脂を硬化させる。
得られた角丸長方形状のナイロン繊維集束体は、図１（ａ）のように、断面寸法が長辺３．１ｍｍ、短辺０．９ｍｍで、その内部に７１％の気孔率を有していた。
この角丸長方形状のナイロン繊維集束体（塗布体用素材１）は、塗布体２として用いる際に、単に切断処理だけで、塗布体２とすることができる。
<Example 1>
Nylon fibers having a fiber thickness of 2 dtex (Deci Tex or dtex) were converged while being adjusted in tension so that the total amount was 4,000 dtex, and wound on a bobbin.
The nylon fiber bundle is pulled out from the bobbin, and the nylon fiber bundle is drawn through a guide having a rectangular hole having an inner dimension of 20 mm long side and 5 mm short side, and the nylon fiber bundle is arranged into a flat shape.
Subsequently, the flattened nylon fiber bundle is passed through a pipe-shaped die having rectangular holes having arcs at both ends with an inner dimension of 3.1 mm long side and 0.9 mm short side, and heated and compressed. After being molded and finished into a rounded rectangular nylon fiber bundle having a long side of 3.1 mm and a short side of 0.9 mm, it is passed through an orifice through a resin solution tank containing a resin solution having the following composition.
(Resin solution composition)
Urethane resin (isocyanate + polyol) 6% by mass
94% by mass of methylene chloride
A nylon fiber bundle impregnated with a resin solution having a rounded rectangular shape is passed through a hot air drying oven set at a temperature of 130 to 140 ° C. to remove the solvent and cure the resin.
The resulting rounded rectangular nylon fiber bundle has a cross-sectional dimension of 3.1 mm long side and 0.9 mm short side as shown in FIG. 1A and a porosity of 71% inside. It was.
When the rounded rectangular nylon fiber bundle (applicator material 1) is used as the applicator 2, the applicator 2 can be simply cut.
実施例１では、パイプ状のダイの空孔の形状を、図１（ａ）のように角丸長方形状としたが、少なくとも長方形や変形三角形、側面視を水滴形状などにすることで、図１（ｂ)〜（ｅ）に示すような、孔の形状に合わせた断面形状の塗布体２とすることができる。
なお、加熱圧縮成形器の入り口側のガイドの空孔の形状を、パイプ状のダイの空孔の形状に合わせることによって、ナイロン繊維束がダイ内に入り込み易いように、ナイロン繊維束の扁平度合いを変えることで、所望の品質のナイロン繊維集束体を容易に製造することができる。
In Example 1, the shape of the hole of the pipe-shaped die is a rounded rectangular shape as shown in FIG. 1 (a). It can be set as the application body 2 of the cross-sectional shape match | combined with the shape of a hole as shown to 1 (b)-( e ).
The flatness of the nylon fiber bundle allows the nylon fiber bundle to easily enter the die by matching the hole shape of the guide on the inlet side of the heat compression molding machine with the shape of the hole of the pipe-shaped die. By changing the above, it is possible to easily manufacture a nylon fiber bundle of desired quality.
さらに、最初にボビンに巻くナイロン繊維の総量を、３，１４６ｄｔｅｘにして製造すると、得られるナイロン繊維集束体の気孔率は７７％に、またナイロン繊維の総量を６，１５０ｄｔｅｘにして製造すると、得られる繊維集束体の気孔率は６５％となる。
柔らかい使用感で、塗布流量を多くしたい場合は気孔率を高く、硬めの使用感で塗布流量を少なめに抑えたい場合は気孔率を低くする等、用途に応じて適宜気孔率を調整することができる。
また、ナイロン繊維の総量の他にも、樹脂組成や得られるナイロン繊維集束体に接着固定する樹脂量を変えることで、使用感や液のフローを調整することが可能である。
Furthermore, when the total amount of nylon fibers wound around the bobbin is manufactured at 3,146 dtex, the resulting nylon fiber bundle has a porosity of 77%, and when the total amount of nylon fibers is manufactured at 6,150 dtex, The porosity of the resulting fiber bundle is 65%.
It is possible to adjust the porosity appropriately according to the application, such as increasing the porosity when you want to increase the application flow rate with a soft feeling of use, and lowering the porosity when you want to suppress the application flow rate slightly with a harder feeling of use. it can.
In addition to the total amount of nylon fibers, it is possible to adjust the feeling of use and the flow of the liquid by changing the resin composition and the amount of resin that is bonded and fixed to the resulting nylon fiber bundle.
前記のようにして得られた気孔率７１％の角丸長方形状のナイロン繊維集束体を長さ４０ｍｍに切断し、いずれか一方の先端部を、図２（ｇ)のように打ち抜き加工し、塗布体２とした。
その際、打ち抜き加工の型を適宜変更することで、図２（ｃ）〜（ｈ）のように、さまざまな形状の塗布体２とすることができる。
また、加工する方法は、打ち抜き加工に限らず、切断により、さらには端面をカットすることだけで図２（ａ），（ｂ）のようにもできる。
The rounded rectangular nylon fiber bundle having a porosity of 71% obtained as described above was cut into a length of 40 mm, and either one of the tip portions was punched as shown in FIG. Application body 2 was obtained.
At that time, by appropriately changing the punching die, it is possible to obtain the application body 2 having various shapes as shown in FIGS.
Further, the processing method is not limited to the punching process, and can be performed as shown in FIGS. 2A and 2B by cutting and further cutting the end face.
なお、この発明においては、長尺の塗布体用素材１を切断するだけで、あるいは先端部に打抜き加工又はカット処理という簡単な加工を施すことによって、即座に用途に応じた塗布体２が形成されるのであるが、目的に応じて、切削、研磨など周知の方法で加工することも当然のことであるが可能なものである。 In addition, in this invention, the application body 2 according to a use is formed immediately by cut | disconnecting the elongate application | coating raw material 1 or giving a simple process of a punching process or a cutting process to the front-end | tip part. However, depending on the purpose, it is naturally possible to perform processing by a known method such as cutting or polishing.
その後、図２（ｇ）の形状に得られた塗布体２（気孔率７１％）を、図３のように黒色のアイライナ液を含む中綿式のペン形状の塗布具本体４に、先端部が６ｍｍ突出するようにして取り付け、化粧用の塗布具５とした。
この化粧用の塗布具５を使用して肌にラインを書いたところ、塗布体２の厚みが薄いこと、ナイロン繊維特有の吸湿性によりアイライナ液の水分を塗布体が吸収して軟化し、塗布体２が適度に撓んで、非常に肌触りのよい塗布具（アイライナ）となった。
さらに、塗布体２の薄肉である厚み方向に線を引くと細線が描け、厚みのある幅方向に塗布体２を撓ませて線を引くと太線が描け、見た目もスマートな、優れた化粧用の塗布具５が得られた。
Thereafter, the applied body 2 (porosity 71%) obtained in the shape of FIG. 2 (g) is applied to the batting type pen-shaped applicator body 4 containing black eyeliner liquid as shown in FIG. The cosmetic applicator 5 was attached so as to protrude 6 mm.
When this cosmetic applicator 5 is used to write a line on the skin, the applied body 2 is thin, and the hygroscopic property of nylon fibers absorbs the moisture of the eyeliner liquid and softens it. The body 2 was bent moderately, and the applicator (eyeliner) had a very good touch.
Furthermore, if a thin line is drawn in the thickness direction of the coated body 2, a fine line can be drawn, and if the coated body 2 is bent in the thick width direction and a line is drawn, a thick line can be drawn, and it looks smart and has excellent makeup. The applicator 5 was obtained.

得られた塗布体２の先端部を、図２（ａ）のようにカットして、図３のように黒色のアイライナ液を含む中綿式の、ペン形状の塗布具本体４に先端部が６ｍｍ出るように取り付け、化粧用の塗布具５とした。
また、ナイロン繊維をポリエステル繊維に変えた以外は同様の製造方法で、前記と同様に長辺が３ｍｍで、短辺がそれぞれ０．９ｍｍ、１．５ｍｍ、１．８ｍｍ、２．０ｍｍ（対象例６〜９）となるような塗布体２を得て、前記と同様に化粧用の塗布具５とした。

実施例２〜４、対象例５〜９で得られた塗布具５に、図４に示したような荷重測定機６の、２０°に傾斜した圧縮板７を塗布体２の先端が長辺側に折れるように押し当て、ペン先（塗布体２）が折れるまでの最大荷重を測定した。
また、使用感を肌に書いて評価した。その結果を図５と表１に示す。
<Performance evaluation>
For the applicator 5 obtained in Examples 2 to 4 and Target Examples 5 to 9, the tip of the applicator 2 has the long side of the compression plate 7 of the load measuring device 6 as shown in FIG. It pressed so that it might bend to the side, and measured the maximum load until a pen point (application body 2) broke.
Moreover, the usability was written on the skin and evaluated. The results are shown in FIG.
この結果から、ポリエステル製の塗布体に比べ、明らかにナイロン製の塗布体の方が、厚みを厚くして行っても硬くなりづらく、柔らかい使用感を実現できる化粧用の塗布具として、好適なものであることが分かった。 From this result, it is clear that the nylon coated body is harder to be hardened even when the thickness is increased, and is suitable as a cosmetic applicator that can realize a soft feeling of use compared to the polyester coated body. It turned out to be a thing.
塗布体２が肌に接することを考えると、最大荷重が５〜１５０ｇが好ましく、１０５ｇ以下がさらに好ましい。より好ましいのは、最大荷重が１５〜８０ｇのものである。
最大荷重が１５０ｇを超えるものは硬いので、使用時に肌に痛く、化粧用としては好ましくない。最大荷重が５ｇ以下の場合には、塗布体がペラペラで使用できない。
Considering that the application body 2 is in contact with the skin, the maximum load is preferably 5 to 150 g, and more preferably 105 g or less. More preferably, the maximum load is 15 to 80 g.
Those whose maximum load exceeds 150 g are hard, so they hurt the skin during use and are not preferable for cosmetic use. When the maximum load is 5 g or less, the coated body cannot be used with a slick surface.
なお、筆記具用途として筆記インクを塗布する塗布体とするならば、最大荷重が１５０〜１０，０００ｇまでのものが適度な強度を有し、筆記具用ペン先としては好ましい。
最大荷重が１５０ｇ以下は、筆記用具としては柔らかすぎ、１０，０００ｇを超えるものは気孔率が低く成り過ぎ、インクが円滑に流れ出ない。
In addition, if it is set as the application body which apply | coats writing ink as a writing instrument use, a thing with a maximum load of 150-10,000g has moderate intensity | strength , and it is preferable as a pen tip for writing instruments.
When the maximum load is 150 g or less, the writing instrument is too soft, and when it exceeds 10,000 g, the porosity is too low and the ink does not flow out smoothly.
＜実施例１０＞
実施例１と同様の方法で、ナイロン繊維の総量を３，１４６ｄｔｅｘにして、気孔率７７％の塗布体２を得た。
これを、図３に示すように、黒色のアイライナ液を含む中綿式のペン形状の塗布具本体４に、先端部が６．５ｍｍ出るように取り付け、化粧用の塗布具５とした。
この化粧用の塗布具５を使用して肌にラインを書いたところ、実施例１の塗布体２より気孔率が高くなっているため、きわめてソフトな使用感の化粧用の塗布具５が得られた。
<Example 10>
In the same manner as in Example 1, the total amount of nylon fibers was changed to 3,146 dtex to obtain a coated body 2 having a porosity of 77%.
As shown in FIG. 3, this was attached to a batting type pen-shaped applicator main body 4 containing a black eyeliner solution so that the tip portion would be 6.5 mm, and a cosmetic applicator 5 was obtained.
When a line was written on the skin using this cosmetic applicator 5, the porosity was higher than that of the applicator 2 of Example 1, so that the cosmetic applicator 5 having a very soft feeling was obtained. It was.
ところが、塗布体２がきわめてソフトなため、少し力を入れて化粧料を塗布すると、塗布体２の根元（塗布具本体４の口部付近）から折れ易いことが気になる場合がある。
そのような場合には、塗布具本体４の口部に、図６のような塗布体２の両側面（長辺側）を支持する、中央部に塗布具２を挟持するスリットを有する支持機構８を取り付けることが好ましい。
図６では、塗布体２の塗布具本体４の口部からの突出長さが６．５ｍｍで、支持機構８の長さを３．５ｍｍとしている。
However, since the application body 2 is very soft, there is a case where it is easy to break from the root of the application body 2 (near the mouth of the applicator main body 4) when applying cosmetics with a little effort.
In such a case, a support mechanism having a slit for holding the applicator 2 at the center, which supports both side surfaces (long sides) of the applicator 2 as shown in FIG. 8 is preferably attached.
In FIG. 6, the protrusion length of the applicator 2 from the mouth of the applicator main body 4 is 6.5 mm, and the length of the support mechanism 8 is 3.5 mm.
この支持機構８は、図６で示したような塗布体２の両側面に配置することに限らず、図７で示すように、塗布具本体４の口部に固定するための取付部を有する断面Ｌ字状の一枚の板状体で構成し、その垂直面を前記塗布体２の片側面に近接させて配置させることでも同様の効果を得ることができので、その構成については、塗布体２の折れ曲がりを防止できるものであれば、特段の制限はない。 The support mechanism 8 is not limited to being disposed on both sides of the applicator 2 as shown in FIG. 6, and has an attachment portion for fixing to the mouth of the applicator main body 4 as shown in FIG. 7. It is possible to obtain the same effect by arranging a single plate-like body having an L-shaped cross section and placing the vertical surface close to one side surface of the application body 2. There is no particular limitation as long as the body 2 can be prevented from bending.
前記支持機構８を使用すれば、塗布体２が根元から折れ難く、なおかつ本願発明品特有のきわめて柔らかい使用感を両立することが可能となる。 If the support mechanism 8 is used, the applied body 2 is difficult to break from the base, and it is possible to achieve both a very soft feeling of use unique to the product of the present invention.
