Abstract
Description
本発明は、着用性に優れ、スポーツ手袋や作業手袋などの手袋に本来求められるグリップ性などの外面側が有する機能を最大限に発揮しうる手袋を提供するものであり、特に、グリップ性が損なわれがちなウェット時においてもその機能性が乾燥と大きな差なく発揮される上、着脱はスムーズに行なえる手袋に関する。 The present invention provides a glove that is excellent in wearability and capable of maximizing the functions of the outer surface, such as grip characteristics originally required for gloves such as sports gloves and work gloves, and particularly, the grip characteristics are impaired. The present invention relates to a glove that can be easily attached and detached while its functionality is not much different from dryness even when it is often wet.
従来より、手袋はウェット時（汗、水などによって濡れた際）に手のひらに接する側の手袋内部の部材と手のひらが滑りやすくあるいはズレやすくなり、グリップ性や作業性などの手袋本来の機能性が低下してしまうといった問題があった。特にグリップ性を重視するスポーツ手袋や作業用手袋などにおいてその問題は顕著であった。
これまでに手袋のグリップ性そのものを向上させる方法としては、例えば、ゴム等の樹脂フィルム製の手袋を使用する方法が採用されていた。しかしながら、着用する手に十分密着していなければ外面側が発揮できるグリップ性は結局は不十分となり、一方着用する手に十分密着している場合はグリップ力は向上するものの手袋の着脱がスムーズに行なえないといった問題が発生していた。また、手のひら側のグリップ性を向上させ、手のひらと手袋との滑りを防止する別の方法として、手袋用部材の表裏両面に小突起物を有するシートを手袋の内側となる面に付着させる方法（例えば、特許文献１。）や、把持側部の少なくとも１本の指と直接接触する内表面に、多数個の弾性体からなる突起が設けられたゴルフ手袋（例えば、特許文献２。）が開示されている。しかし、これらは着用時に手を入れる段階で入れにくさを感じたり、着用中に突起の存在により違和感を感じ、着用感に劣るといった問題点があった。また、特にゴルフ手袋用部材の用途分野においては、手袋の外面側になる面に凹凸や段差を設けた部材の使用自体が手袋に関するルール上から適さない部材である。
Traditionally, when gloves are wet (when wet with sweat, water, etc.), the material inside the glove that comes in contact with the palm and the palm of the glove are slippery or slippery, and the original functionality of the glove, such as grip and workability, is improved. There was a problem of being lowered. The problem was particularly noticeable in sports gloves and work gloves that emphasize grip.
So far, as a method for improving the grip performance of the glove itself, for example, a method using a glove made of a resin film such as rubber has been adopted. However, the grip which can be exhibited on the outer surface side will be insufficient if it is not in close contact with the wearing hand. On the other hand, if it is in close contact with the wearing hand, the grip will be improved, but the gloves can be attached and detached smoothly. There was a problem that there was not. In addition, as another method for improving the grip on the palm side and preventing slipping between the palm and the glove, a method of attaching a sheet having small protrusions on both the front and back sides of the glove member to the inner surface of the glove ( For example, Patent Document 1) and golf gloves (for example, Patent Document 2) in which protrusions made of a large number of elastic bodies are provided on an inner surface that directly contacts at least one finger on the grip side portion. Has been. However, these have problems that it is difficult to put them in at the stage of putting their hands at the time of wearing, or that they feel uncomfortable due to the presence of protrusions during wearing, resulting in poor wearing feeling. In particular, in the field of application of golf glove members, the use of a member having irregularities or steps on the outer surface side of the glove is a member that is not suitable from the rules regarding gloves.
上記のように、従来公知の方法では、手袋の脱着のスムーズ性、手入れ感や着用感を損なうことなく、着用した手との滑りやズレなどを防止することで、特にスポーツ手袋や作業用手袋に代表される手袋に求められるようなグリップ性などの機能性を安定して発揮させ、かつそのズレ防止機能がウェット時においても大きく低下することのないような優れた着用性が実現できないといった課題があった。
本発明は、手袋の着脱のスムーズさおよび手入れ感がよく、かつ着用中に汗で濡れても手袋と手のひらのズレやヨジレが出にくいことで、従来にない良好なグリップ性等の本来の機能性を発揮しうる手袋を提供することを目的とする。
As described above, the conventionally known methods prevent slippage or slippage with the worn hand without impairing the smoothness and care of the gloves and the feeling of wearing, and in particular, sports gloves and work gloves. The ability to stably exhibit the functionality such as grip required as represented by gloves, and the excellent wearability that the displacement prevention function does not greatly decrease even when wet cannot be realized was there.
The present invention has an original function such as a good grip and the like that is unprecedented because it is easy to put on and take off gloves and is easy to care for, and even if it gets wet with sweat while wearing, it is difficult to cause slippage and twisting of the glove and palm. An object is to provide a glove capable of exerting sex.

It is found that it is excellent in the effect of improving the grip property at the time, and furthermore, the surface of the hollow nanosilica particles to be used is surface-modified with a functional group typified by an isocyanate group to impair the tactile sensation when dry The present invention has been found that it can be uniformly present on the surface of the fiber, is excellent in the durability of the grip improvement effect by the hollow nanosilica particles, and is smooth and easy to care at the time of attachment and detachment. .

An example of a method for producing artificial leather suitable for the glove member of the present invention is shown below.
The artificial leather suitable for the glove member of the present invention is a multicomponent fiber obtained by spinning at least two types of polymers having different solubility (a polymer having a single fiber cross-sectional shape as a dispersion medium). A sea-island structure or a multi-core core-sheath structure fiber or an alternating-joint-type split-structure fiber) containing at least two kinds of non-polymers. Polyesters containing aromatic rings such as polyethylene terephthalate, polybutylene terephthalate, etc., nylon-6, nylon-6.6, nylon-6.10.

Furthermore, the mass ratio of the ultrafine fiber entangled body after removal of the removed fiber component and the polymer elastic body is more preferably 35/65 to 90/10. In addition, the polymer elastic body contained in the fiber entangled body may be dot-like or sponge-like (porous), but if it is sponge-like, the texture of the artificial leather obtained is more flexible. It has a feeling of swelling and can impart good tactile sensation and cushioning properties while maintaining lightness.
Next, in order to impart a natural leather-like soft hand and a glove-like hand to the three-dimensional entangled nonwoven fabric, the removal component forming the multi-component fiber phase is dissolved or Separated and removed to obtain a fiber entangled body composed of a bundle of ultrafine fibers. This fiber entangled body is sliced to an appropriate thickness, or without being sliced, a polymer film mainly composed of an elastic polymer is made in advance and bonded, or a polymer solution or dispersion is applied to form a film A polymer coating layer is formed by a method such as heat treatment, and a heat-pressed process, a coloring process, a softening process, and the like are performed as necessary to finish an artificial leather with silver. Alternatively, a fiber raised surface is formed by buffing or the like on the surface and finished into a suede-like artificial leather.
The artificial leather is preferably in the range of an apparent density of 0.25 to 0.75 g / m 3 because it can be easily adapted as a member for gloves.
ここに得た人工皮革は用途に応じて厚さを調節し、型に裁断し、縫製加工する。手袋用部材としては、得られた人工皮革をそのまま1枚物で手袋の裏表を構成する部材としても、手にあたる部材のみとしても、或は他の部材と積層して手袋の表用の部材としても裏用の部材としても特に限定することは無い。
特に、平均繊度０．０００１〜０．７ｄｔｅｘの極細繊維からなる繊維質基材表面が手のひらに接する部材とすることが好ましい。０．０００１ｄｔｅｘ以上とすることで、手袋にしたときの機械物性に優れ、０．７ｄｔｅｘ以下、特には０．３ｄｔｅｘ以下とすることで後述の中空ナノシリカ粒子の付着状態に起因するウェット時のグリップ性、着脱のスムーズさおよび手袋の着用感に優れる点で好ましい。
The artificial leather obtained here is adjusted in thickness according to the intended use, cut into a mold, and sewn. As a member for gloves, as a member for constituting the front and back of the glove as a member constituting the back and front of the glove with one piece of the artificial leather as it is, or as a member corresponding to the hand, or laminated with other members There is no particular limitation on the back member.
In particular, it is preferable that the surface of the fibrous base material made of ultrafine fibers having an average fineness of 0.0001 to 0.7 dtex is in contact with the palm. By making it 0.0001 dtex or more, excellent mechanical properties when used as a glove, 0.7 dtex or less, particularly 0.3 dtex or less, grip properties when wet due to the adhesion state of the hollow nanosilica particles described later It is preferable in terms of excellent smoothness of attachment and detachment and a feeling of wearing gloves.
次に、本発明で使用する中空ナノシリカ粒子について詳述する。本発明で用いられる中空ナノシリカ粒子は、緻密なシリカ殻を有するバルーン構造（中空状）の微細粒子であり、中空ナノシリカ粒子は緻密なシリカ殻を有するバルーン構造（中空状）、ナノサイズの分散性に優れたシリカ粒子であり、例えば、特開２００５−２６３５５０号公報、特開２００６−２５６９２１号公報記載の方法により製造される。中空ナノシリカ粒子の一次粒径は５０〜１５０ｎｍである。また、シリカ殻の厚さ（透過型電子顕微鏡（ＴＥＭ））は５〜１５ｎｍ、比表面積（ＢＥＴ法）は１５０〜３００ｍ2／ｇ、細孔容積（水銀圧入法）は９０００〜１３０００ｍｍ3／ｇ、かさ密度は０．０３〜０．０７ｇ／ｍＬおよび殻壁細孔は５ｎｍ以下（ＴＥＭによる直接観察限界以下）であり、好ましくは２ｎｍ以下（ＢＥＴ法）であることが好ましい。さらに、前記中空ナノシリカ粒子の表面が官能基により修飾された表面修飾粒子であることがより好ましい。表面修飾粒子は特開２００７−９９６０７号公報に記載のものが好ましく用いられる。官能基の例としては、イソシアネート基、アルキル基、アリール基、ＵＶ官能基などが挙げられる。ここで言うＵＶ官能基とは、ビニル基、スチリル基、アクリル基など紫外線（ＵＶ）により反応する官能基である。これらの官能基は、本発明を構成する繊維質基材や高分子弾性体として何を選択するかによって適切な官能基が異なるが、例えば繊維質基材にポリアミド樹脂やポリエステル樹脂、高分子弾性体にポリウレタン樹脂を選択した場合は、イソシアネート基が好ましい。このような表面修飾粒子は、ナノサイズのシリカ粒子の分散性を向上する目的で発明されたものであるが、本発明においては、得られる上記した効果が永続的に発揮されることに寄与している。それは、官能基と人工皮革等で代表される基材が反応し、強固にナノシリカが密着するためであると考えている。表面修飾粒子の市販品は、ナノタッチ（登録商標）としてグランデックス（株）から入手可能である。 Next, the hollow nano silica particles used in the present invention will be described in detail. The hollow nanosilica particles used in the present invention are fine particles of a balloon structure (hollow shape) having a dense silica shell, and the hollow nanosilica particles are a balloon structure (hollow shape) having a dense silica shell, nano-sized dispersibility. For example, the silica particles are produced by the methods described in JP-A Nos. 2005-263550 and 2006-256921. The primary particle size of the hollow nanosilica particles is 50 to 150 nm. The silica shell thickness (transmission electron microscope (TEM)) is 5 to 15 nm, the specific surface area (BET method) is 150 to 300 m 2 / g, and the pore volume (mercury intrusion method) is 9000 to 13000 mm 3 / g. The bulk density is 0.03 to 0.07 g / mL and the shell wall pores are 5 nm or less (below the direct observation limit by TEM), preferably 2 nm or less (BET method). Furthermore, it is more preferable that the surface of the hollow nanosilica particle is a surface-modified particle modified with a functional group. As the surface modified particles, those described in JP-A-2007-99607 are preferably used. Examples of functional groups include isocyanate groups, alkyl groups, aryl groups, UV functional groups, and the like. The UV functional group mentioned here is a functional group that reacts with ultraviolet rays (UV) such as a vinyl group, a styryl group, and an acrylic group. These functional groups have different functional groups depending on what is selected as the fibrous base material or polymer elastic body constituting the present invention. For example, a polyamide resin, a polyester resin, or a polymer elastic material is used for the fibrous base material. When a polyurethane resin is selected for the body, an isocyanate group is preferred. Such surface-modified particles were invented for the purpose of improving the dispersibility of the nano-sized silica particles, but in the present invention, they contribute to the permanent achievement of the obtained effects. ing. This is considered to be due to the reaction between the functional group and the substrate represented by artificial leather and the like, and the nanosilica adheres firmly. A commercially available product of surface-modified particles is available from Grandex Co., Ltd. as Nanotouch (registered trademark).
基材に前記中空ナノシリカ粒子およびまたは表面修飾粒子を付着させる方法としては、グラビア塗布方式やスプレー塗布方式、ナイフ塗布方式、バーコーター方式等、表面に選択的に付着させる方法と、含浸・乾燥して繊維質基材の厚み方向の全層に付着させる方法がある。中空ナノシリカ粒子は、メタノール、エタノール等の脂肪族アルコール類、ｎ−ヘキサン等の脂肪族炭化水素類、トルエン、キシレン等の芳香族炭化水素類、アセトン、メチルエチルケトン（ＭＥＫ）、メチルイソブチルケトン（ＭＩＢＫ）等のケトン類などの有機溶剤や、水に分散させた分散液として用いる。付着方法は自由に選択することが出来るが、グラビア塗布が表面選択塗布であり、グラビアメッシュや塗布回数を自由に調整できるため所望の塗布量が得やすく、好ましい。
前記分散液の中空ナノシリカ粒子の固形分濃度は１〜１０質量％であることが好ましい。濃度が低すぎると塗布時に基材内部へ過剰に浸透してしまい、一方、濃度が濃すぎると塗布時に一次粒子の状態で存在する中空ナノシリカ粒子が急激に減少してしまうので、前記好ましい濃度範囲を外れると目的とする表面での存在状態が得られにくくなる。また、乾燥後（溶剤除去後）の基材表面上への塗布量が、０．０２〜０．８ｇ／ｍ２になるように塗布するのが好ましい。より好ましい塗布量は、０．０５〜０．５ｇ／ｍ２である。
なお、前記中空ナノシリカ粒子は、本発明の手袋の手のひらに接する部材の少なくとも手のひら側表面に付着していることが必須であるが、手の甲に接する部材の少なくとも手の甲側表面に付着させることが、ウェット時の着脱性がスムーズとなり、着用性やウェット時のグリップ性がより優れる点で好ましい。
以上のようにして得られた手袋は、ウェット時にも良好なグリップ性があり、スポーツ手袋や作業手袋に好適である。
Examples of the method for attaching the hollow nanosilica particles and / or the surface-modified particles to the substrate include a gravure coating method, a spray coating method, a knife coating method, a bar coater method, a method of selectively attaching to the surface, and impregnation / drying. There is a method of adhering to all layers in the thickness direction of the fibrous base material. Hollow nanosilica particles include aliphatic alcohols such as methanol and ethanol, aliphatic hydrocarbons such as n-hexane, aromatic hydrocarbons such as toluene and xylene, acetone, methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK). It is used as an organic solvent such as ketones or a dispersion liquid dispersed in water. Although an adhesion method can be selected freely, gravure coating is surface selective coating, and a gravure mesh and the number of coatings can be freely adjusted, so that a desired coating amount can be easily obtained, which is preferable.
The solid content concentration of the hollow nanosilica particles in the dispersion is preferably 1 to 10% by mass. If the concentration is too low, it will excessively penetrate into the substrate during coating, while if the concentration is too high, the hollow nanosilica particles present in the state of primary particles during coating will rapidly decrease. If it is off, it will be difficult to obtain the desired state of existence on the surface. Moreover, it is preferable to apply | coat so that the application quantity on the base-material surface after drying (after solvent removal) may be 0.02-0.8 g / m < 2 >. A more preferable coating amount is 0.05 to 0.5 g / m 2 .
It is essential that the hollow nanosilica particles adhere to at least the palm side surface of the member that contacts the palm of the glove of the present invention, but it is wet to adhere to at least the back side surface of the member that contacts the back of the hand. It is preferable in that the attachment / detachment at the time becomes smooth, and the wearability and the grip property when wet are more excellent.
The gloves obtained as described above have good grip properties even when wet, and are suitable for sports gloves and work gloves.

平均繊度０．０１ｄｔｅｘのナイロン−６極細繊維の繊維束からなる繊維絡合体の内部に多孔質状ポリエステル系ポリウレタンが含有された厚さ０．５ｍｍの繊維質基材の片面を＃４００のサンドペーパーで起毛し、スエード調人工皮革を得た。得られたスエード調人工皮革をウインス染色機を用いて含金染料で黒色に染色し、スエード調人工皮革１を得た。一方、官能基変性のない一次粒径が５０〜１５０ｎｍ、シリカ殻の厚さ５〜１５ｎｍおよび殻壁細孔２ｎｍ以下の中空ナノシリカ粒子を２％含有する均一なＭＥＫ分散液を調整した。この分散液を前記スエード調人工皮革の非立毛面に１５０メッシュのグラビアロールを用いて塗布し（塗布量：中空ナノシリカ粒子０．２ｇ／ｍ２）、１３０℃に設定した熱風乾燥機内で乾燥させることで、中空ナノシリカ粒子が非立毛面に付着したスエード調人工皮革２を得た。このスエード調人工皮革２の中空ナノシリカ粒子付着面のドライ時、ウェット時の動摩擦係数を測定したところ、ウェット時に高い動摩擦係数を示した。その結果を表１に示す。なお、摩擦係数の測定には摩擦感テスターＫＥＳ−ＳＥ（カトーテック株式会社製）を使用し、１ｍｍ／ｓｅｃ、荷重５０ｇにて測定した。ウェット時の摩擦係数は、スエード調人工皮革を２４時間蒸留水に浸漬し、取り出した後にろ紙で余分な水分を拭き取って測定した。また、スエード調人工皮革２の中空ナノシリカ粒子付着面を、手のひら側の部材においては手のひらと接する面とし、手の甲側の部材においては手の甲と接する面としてゴルフ手袋を縫製し、１０人のパネリストにて着用試験を行った結果、手を入れる際にはサラサラとして手入れ感が良く、汗をかいてくると密着性が増して手袋がよじれずに安定したスウィングができ、手袋を脱ぐ際にも脱ぎやすいという評価が多かった。
Example 1
# 400 sandpaper on one side of a 0.5 mm thick fibrous base material containing a porous polyester-based polyurethane inside a fiber entanglement made of a bundle of nylon-6 ultrafine fibers with an average fineness of 0.01 dtex To raise suede-like artificial leather. The obtained suede-like artificial leather was dyed black with a metal-containing dye using a Wins dyeing machine to obtain a suede-like artificial leather 1. On the other hand, a uniform MEK dispersion containing 2% of hollow nanosilica particles having a primary particle size without functional group modification of 50 to 150 nm, a silica shell thickness of 5 to 15 nm and shell wall pores of 2 nm or less was prepared. This dispersion is applied to the non-raised surface of the suede-like artificial leather using a 150 mesh gravure roll (coating amount: hollow nanosilica particles 0.2 g / m 2 ) and dried in a hot air dryer set at 130 ° C. Thus, the suede-like artificial leather 2 in which the hollow nanosilica particles adhered to the non-raised surface was obtained. When the dynamic friction coefficient was measured when the hollow nanosilica particle adhering surface of the suede-like artificial leather 2 was dry and wet, it showed a high dynamic friction coefficient when wet. The results are shown in Table 1. The friction coefficient was measured using a friction tester KES-SE (manufactured by Kato Tech Co., Ltd.) at 1 mm / sec and a load of 50 g. The coefficient of friction when wet was measured by immersing suede-like artificial leather in distilled water for 24 hours, removing the excess moisture with a filter paper after removal. In addition, the surface of the suede-like artificial leather 2 on which the hollow nanosilica particles are attached is a surface in contact with the palm of the palm side member, and a golf glove is sewn as a surface in contact with the back of the hand on the back side member. As a result of the wearing test, when you put your hands in, it feels good as a smooth, and when you sweat, you can improve the adhesion and stable swing without twisting the gloves, easy to take off when you take off the gloves There were many evaluations.
実施例２

The obtained suede-like artificial leather was dyed brown with a disperse dye using a circular dyeing machine to obtain a suede-like artificial leather 3. On the other hand, it contains 2% of surface modified particles obtained by surface modification of hollow nanosilica particles having a primary particle size of 50 to 150 nm, a silica shell thickness of 5 to 15 nm and shell wall pores of 2 nm or less with an isocyanate group by the method described in the above document. A uniform aqueous dispersion was prepared. This dispersion is applied to the non-raised surface of the suede-like artificial leather using a 150 mesh gravure roll (coating amount: hollow nanosilica particles 0.2 g / m 2 ) and dried in a hot air dryer set at 130 ° C. Thus, the suede-like artificial leather 4 in which the hollow nanosilica particles adhered to the non-raised surface was obtained. The dry and wet dynamic friction coefficient of the suede-like artificial leather 4 adhering surface of the hollow nanosilica particles was measured in the same manner as in Example 1, and showed a high dynamic friction coefficient when wet. The results are shown in Table 1. In addition, the hollow nanosilica particle adhering surface of the suede-like artificial leather 4 is a surface in contact with the palm of the palm-side member, and a work glove is sewn as a surface in contact with the back of the hand of the member on the back of the hand. As a result of the wearing test, when putting a hand, it was easy to feel as smooth, and when sweating, it was highly evaluated that the adhesion increased and the tool was easy to grip.
