【発明の属する技術分野】
本発明は、家庭における洗濯、炊事、園芸作業や、電子部品や精密機器の組み立てなどにおいて好適に使用される作業用手袋に関するものである。
【０００２】
【従来の技術】
従来から家庭用手袋としては一般的に、特許文献１に開示されているように内面に植毛をしたもの、内面をアクリル樹脂でコーティングしたもの、主にゴム材料ではクロリネーション（塩素化処理）したものが利用されている。クロリネーションもしくはアクリル樹脂でコーティングした手袋は、植毛などの脱離が嫌われる作業場で主に使用されている。これらの手袋の装着は抵抗なくスムーズに行なえるが、作業終了後に手袋を脱ごうとするとき、特に手が発汗していると指先を引っ張っただけでは脱げず、手袋の裾から反転させてようやく脱げるというのが常である。そこで、脱ぎ易さを向上させるために１度漬けにより作られた手袋の被膜層に粒子を多く混在させて内面に凹凸を付けた場合は脱ぎ易くはなるが、硬くなって弾力性がなくなり、風合いが悪くなる。内面に粒子を添加したアクリル樹脂のコーティング層を設けた手袋の場合は、アクリル樹脂が低粘度のため、粒子が沈降を起こし、加工できたとしてもアクリル樹脂のコーティング層の肉厚が１μｍ〜３μｍと薄いため、粒子がコーティング層から容易に脱離してしまうという問題がある。

【発明が解決しようとする課題】
本発明はこのような課題を解決するもので、風合いに優れ、脱着性にも優れた作業用手袋を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
この課題を解決するために本発明は、ポリ塩化ビニル製樹脂材料またはゴム材料からなり外側に位置する第１被膜層に重ねて、前記第１被膜層と同じ材料もしくは異なった材料からなり粒子が添加されて１０個／ｍｍ^２〜５０個／ｍｍ^２の凸部を有し内側に位置する第２被膜層を形成し、第２被膜層の内面からの凸部の平均高さが５μｍ〜４０μｍであることを要旨とするものである。
【０００６】
以下、本発明について詳細に説明すると、本発明の作業用手袋は、次のような方法により作られる。先ず、第１の方法にて第１被膜層（表側）がゴム製の手袋を製造する場合は、陶器製の手型を硝酸カルシウム、塩化亜鉛、塩化カルシウムなどの２価金属塩のメタノールもしくは水からなる凝固剤に漬け、引き上げて室温乾燥後にゴムコンパウンドへ浸けて第１被膜層を形成し、６０℃〜８０℃、３〜６分間程度の乾燥を行ない、粒子を混合してあるゴムコンパウンドに浸漬して第２被膜層を形成し、６０℃〜８０℃、３〜６分間程度の乾燥を行なう。その後、アクリル樹脂製エマルジョンに３０秒から２分間浸けてから、約７５℃で１時間、約１２０℃で１時間のキュアをそれぞれ行ない、手袋を反転離型してでき上がる。クロリネーションを行なう場合は、手袋を反転離型してから次亜塩素酸ソーダーの塩酸水溶液に１０秒から２分間程度浸けて乾燥させる。また、凝固法だけでなく感熱法を利用した浸漬加工法もしくは塗布法にて加工することもできる。図１および図２にでき上がった手袋を示しており、１は表側に位置する第１被膜層、２は内側に位置する第２被膜層、３は第２被膜層２の内面から突出する粒子の凸部である。
【０００７】
次に、第２の方法にてポリ塩化ビニル樹脂製の手袋を製造する場合は、陶器製の手型をポリ塩化ビニル樹脂製ペーストへ浸けて第１被膜層を形成し、引き上げてから約２００℃、５〜１０分間程度の乾燥後、粒子を混合してあるポリ塩化ビニル樹脂製ペーストに浸けて第２被膜層を形成し、約２００℃、５〜１０分間程度の乾燥を行なう。その後、アクリル樹脂製エマルジョンに３０秒から２分間浸けて第３被膜層を形成してから約２００℃、１０分間のキュアを行ない、手袋を反転離型してでき上がる。図３にでき上がった手袋を要部拡大して示しており、４は表側に位置する第１被膜層、５は第１被膜層４の内側に位置する第２被膜層、６は第２被膜層５の内面から突出する粒子の凸部、７は第２被膜層５の内側に位置する第３被膜層である。図面からも明らかなように、第３被膜層７の厚みは第１被膜層４、第２被膜層５の厚みに比べて非常に薄く（１μｍ〜３μｍ）、凸部６は第３被膜層７より突出して手袋内面に露出している。このポリ塩化ビニル樹脂製の手袋を製造する場合においても第３被膜層を設けずにクロリネーション処理を行なっても同等に脱着性が向上する。
【０００８】
前記第１の方法に使用されるゴム材料とは、天然ゴム、イソプレンゴム、クロロプレンゴム、アクリル酸エステルゴム、スチレン−ブタジエン共重合体ゴム、アクリロニトリル−ブタジエン共重合体ゴム、ウレタンゴム、ブチルゴム、ポリブタジエンゴム、シリコーンゴムなどの単独重合体ラテックスあるいは共重合体ラテックス、１０重量％以下のカルボキシル変性基などを持つ共重合体ラテックスであり、これらをブレンドして、周知の架橋剤、加硫促進剤、老化防止剤、増粘剤、有機や無機の充填剤、可塑剤などを添加したものである。天然ゴムなる語句は、天然ゴム単独だけでなく、天然ゴム−メチルメタクリレート共重合体やエポキシ化変性天然ゴム共重合体（ラテックス）などを包含する。アクリル酸エステルゴムなる語句は、ｎ−ブチルアクリレート、ｎ−ブチルメタクリレート、ｉｓｏ−ブチルアクリレート、ｉｓｏ−ブチルメタクリレート、エチルアクリレート、エチルメタクリレート、２−エチルヘキシルアクリレート、２−エチルヘキシルメタクリレート、ｉｓｏ−プロピルアクリレート、ｉｓｏ−プロピルメタクリレートなどの単独重合体、または共重合体であって、アクリロニトリル、メチルメタクリレート、アリルメタクリレート、Ｎ−メチロールアクリルアミド、アクリル酸、メタクリル酸などを含んだ共重合体を包含する。また、第１の方法に使用されるアクリル樹脂製エマルジョンとは、脱着性をさらに良くするために周知のアクリル系樹脂を主とし、ＮＢＲラテックス、ウレタン樹脂、スチレン樹脂を含み有機、無機粉末を添加した混合エマルジョンである。
【０００９】
また、前記第２の方法に使用される第１皮膜層および第２被膜層の材料であるポリ塩化ビニル製樹脂は、ポリ塩化ビニル樹脂とポリ塩化ビニル−酢酸ビニル共重合体の何れか一方、または両者の混合物を主体とし、周知のフタル酸系、ポリエステル系、アジピン酸系の可塑剤、安定剤、増粘剤、溶剤などを添加したペーストゾルまたはオルガノゾルとしたものを用いる。第２の方法に使用される第３被膜層の材料であるアクリル樹脂製エマルジョンは前記第１の方法に使用されるアクリル樹脂製エマルジョンと同様である。
【００１０】
前記第１皮膜層の肉厚は、実使用に耐えるだけの厚みが必要で１００μｍ〜４００μｍの範囲である。第２皮膜層の厚みは、粒子を添加しているために皮膜強度が弱く硬さが出るので基本的に第１皮膜層より薄くする方が良い。もし肉厚を厚くすると内面に凹凸を出すために粒子の添加部数増加と粒子径の拡大化につながり、柔軟性を損なうので、好ましくは１０μｍ〜５０μｍが良い。添加する粒子は、皮膚との触感が良いものとして角の少ない球状、楕円形が好ましく、材料はウレタン、ＰＭＭＡ、ＰＶＣ、ポリスチレン、セルロースなどの有機物または無機物などを利用でき、平均粒子径は第２皮膜の肉厚より５％〜５０％程度大きなものを選択するのが良い。脱着性とざらつき感は、凸部の高さと単位面積あたりの個数が関与していて好ましい範囲としては、第２被膜層の内面から凸部頂点の平均高さは５μｍ〜４０μｍ、個数は１０個／ｍｍ^２〜５０個／ｍｍ^２が良い。凸部の平均高さが４０μｍ、個数が５０個／ｍｍ^２を超えるとざらつき感が出てきて装着しにくくなる。凸部の平均高さが１０μｍ未満、個数が１０個／ｍｍ^２未満であると、前記従来例と同様に、手袋を脱ごうとするとき、特に手が発汗していると指先を引っ張っただけでは脱げにくいという問題が残る。
【００１１】
このように、ポリ塩化ビニル製樹脂材料またはゴム材料からなり外側に位置する第１被膜層に重ねて、前記第１被膜層と同じ材料もしくは異なった材料からなり粒子が添加されて１０個／ｍｍ^２〜５０個／ｍｍ^２の凸部を有し内側に位置する第２被膜層を形成し、第２被膜層の内面からの凸部の平均高さを５μｍ〜４０μｍとしたことにより、風合いに優れ、脱着性にも優れた作業用手袋を提供することができる。

【表１】

手袋内面のざらつき感と脱着性については、第２皮膜層に粒子を添加することによって凸部の平均高さと単位面積当たりの個数に関係していて、実施例１のように平均高さが５μｍ〜４０μｍ、個数が１０個／ｍｍ^２〜５０個／ｍｍ^２の範囲であれば、ざらつき感もなく脱着性も優れていることが分かる。特に比較例１に示す粒子無添加に比べると手袋を脱ぐときの脱着性が非常に良い。比較例２では添加粒子の平均粒子径が２０μｍと第２皮膜層の厚みより小さいので表面に現れる凸部が少ないので脱ぐのが容易でない。比較例３では凸部の平均高さが５０μｍと高いためにざらつき感があり装着時に引っ掛かる。比較例４は表面の凸部個数が少ないためにざらつき感、装着時のはめやすさは良いが、脱ぐのが容易ではなかった。比較例５では凸部の平均高さと個数が多く、ざらつき感があり、はめにくいという結果になった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to work gloves suitably used for washing, cooking, gardening work at home, assembling of electronic parts and precision equipment, and the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, household gloves generally have a flocked inner surface as disclosed in Patent Literature 1, an inner surface coated with an acrylic resin, and chlorination (chlorination treatment) mainly of a rubber material. Things are being used. Gloves coated with chlorination or acrylic resin are mainly used in workplaces where detachment such as flocking is disliked. These gloves can be worn smoothly without resistance, but when trying to take off gloves after work is completed, especially if the hand is sweating, pulling on the fingertips will not remove them, but only flip them over from the hem of the gloves. I always take it off. Therefore, if a large amount of particles are mixed in the coating layer of the glove made by dipping once to improve the ease of removal, and the inner surface is roughened, it will be easier to remove, but it will be harder and less elastic, The texture worsens. In the case of gloves provided with an acrylic resin coating layer to which particles are added on the inner surface, the acrylic resin has a low viscosity, so that the particles are settled, and even if the glove can be processed, the thickness of the acrylic resin coating layer is 1 μm to 3 μm. Therefore, there is a problem that particles are easily detached from the coating layer.

[Problems to be solved by the invention]
An object of the present invention is to solve such a problem, and an object of the present invention is to provide a working glove excellent in texture and detachability.
[0005]
[Means for Solving the Problems]
In order to solve this problem, the present invention relates to a method of forming a particle made of the same material or a different material as that of the first coating layer on the outer first coating layer made of a polyvinyl chloride resin material or a rubber material. It is added to form a second coating layer having a projection of 10 / mm ² to 50 / mm ² and located inside, and the average height of the projection from the inner surface of the second coating layer is 5 μm to 40 μm The gist is that
[0006]
Hereinafter, the present invention will be described in detail. The working glove of the present invention is made by the following method. First, when manufacturing gloves whose first coating layer (front side) is made of rubber by the first method, a ceramic hand mold is used for methanol or water of a divalent metal salt such as calcium nitrate, zinc chloride or calcium chloride. Immersed in a coagulant, pulled up, dried at room temperature, immersed in a rubber compound to form a first coating layer, dried at 60 ° C. to 80 ° C. for about 3 to 6 minutes, and mixed with a rubber compound containing particles. It is immersed to form a second coating layer, and dried at 60 ° C. to 80 ° C. for about 3 to 6 minutes. Then, after soaking in an acrylic resin emulsion for 30 seconds to 2 minutes, curing is carried out at about 75 ° C. for 1 hour and at about 120 ° C. for 1 hour, respectively. When performing chlorination, the glove is inverted and released, and then dipped in a hydrochloric acid aqueous solution of sodium hypochlorite for about 10 seconds to 2 minutes and dried. Further, not only the solidification method but also a dip processing method or a coating method using a heat-sensitive method can be used. 1 and 2 show the finished glove, wherein 1 is the first coating layer located on the front side, 2 is the second coating layer located on the inside, 3 is the particle of the protruding particles from the inner surface of the second coating layer 2. It is a convex part.
[0007]
Next, in the case of manufacturing polyvinyl chloride resin gloves by the second method, a ceramic mold is dipped in a polyvinyl chloride resin paste to form a first coating layer. After drying at 5 [deg.] C. for about 5 to 10 minutes, the particles are immersed in a mixed polyvinyl chloride resin paste to form a second coating layer, and dried at about 200 [deg.] C. for about 5 to 10 minutes. Thereafter, the film is immersed in an acrylic resin emulsion for 30 seconds to 2 minutes to form a third coating layer, then cured at about 200 ° C. for 10 minutes, and the glove is turned upside down and released. FIG. 3 is an enlarged view of a main part of the finished glove, where 4 is a first coating layer located on the front side, 5 is a second coating layer located inside the first coating layer 4, and 6 is a second coating layer. The protrusions 7 of the particles protruding from the inner surface of 5 are third coating layers located inside the second coating layer 5. As is clear from the drawing, the thickness of the third coating layer 7 is very thin (1 μm to 3 μm) as compared with the thickness of the first coating layer 4 and the second coating layer 5, and the projection 6 is formed of the third coating layer 7. It is more protruding and is exposed on the inner surface of the glove. Even in the case of producing this glove made of a polyvinyl chloride resin, even if a chlorination treatment is performed without providing the third coating layer, the removability is equivalently improved.
[0008]
The rubber materials used in the first method include natural rubber, isoprene rubber, chloroprene rubber, acrylate rubber, styrene-butadiene copolymer rubber, acrylonitrile-butadiene copolymer rubber, urethane rubber, butyl rubber, and polybutadiene. Rubber, a latex of a homopolymer such as silicone rubber or a copolymer latex having a carboxyl-modified group of 10% by weight or less, and blending these to form a well-known crosslinking agent, vulcanization accelerator, An anti-aging agent, a thickener, an organic or inorganic filler, a plasticizer and the like are added. The term natural rubber includes not only natural rubber alone but also natural rubber-methyl methacrylate copolymer and epoxidized modified natural rubber copolymer (latex). The term acrylic ester rubber is n-butyl acrylate, n-butyl methacrylate, iso-butyl acrylate, iso-butyl methacrylate, ethyl acrylate, ethyl methacrylate, 2-ethylhexyl acrylate, 2-ethylhexyl methacrylate, iso-propyl acrylate, iso A homopolymer such as -propyl methacrylate or a copolymer, including a copolymer containing acrylonitrile, methyl methacrylate, allyl methacrylate, N-methylolacrylamide, acrylic acid, methacrylic acid, and the like. The acrylic resin emulsion used in the first method is mainly composed of a well-known acrylic resin in order to further improve the desorption property, and contains NBR latex, urethane resin, styrene resin, and organic and inorganic powders. This is a mixed emulsion.
[0009]
Further, the polyvinyl chloride resin as the material of the first coating layer and the second coating layer used in the second method is one of a polyvinyl chloride resin and a polyvinyl chloride-vinyl acetate copolymer, Alternatively, a paste sol or an organosol containing a phthalic acid-based, polyester-based, or adipic acid-based plasticizer, a stabilizer, a thickener, a solvent, or the like as a main component is used. The acrylic resin emulsion used as the material of the third coating layer used in the second method is the same as the acrylic resin emulsion used in the first method.
[0010]
The thickness of the first coating layer is required to be sufficient for practical use, and is in the range of 100 μm to 400 μm. Basically, the thickness of the second coating layer is preferably smaller than that of the first coating layer because the addition of the particles results in a low coating strength and high hardness. If the thickness is increased, irregularities are formed on the inner surface, which leads to an increase in the number of added particles and an increase in the particle diameter, and impairs flexibility. Therefore, the thickness is preferably 10 μm to 50 μm. The particles to be added are preferably spherical or elliptical with small corners so as to have a good touch with the skin. The material may be an organic or inorganic substance such as urethane, PMMA, PVC, polystyrene, or cellulose. It is better to select a film about 5% to 50% larger than the thickness of the film. The detachability and the roughness are preferably related to the height of the projections and the number per unit area, and the average height of the tops of the projections from the inner surface of the second coating layer is 5 μm to 40 μm, and the number is 10 pieces. / Mm ² to 50 pieces / mm ² are good. If the average height of the projections is more than 40 μm and the number of the projections exceeds 50 / mm ² , a feeling of roughness appears and it becomes difficult to attach the projections. When the average height of the projections is less than 10 μm and the number is less than 10 / mm ² , when the gloves are to be taken off similarly to the conventional example, the fingertip is simply pulled when the hand is sweating. Then, the problem that it is difficult to take off remains.
[0011]
In this way, particles made of the same material or a different material as the first coating layer are added to the outer first coating layer made of a polyvinyl chloride resin material or a rubber material, and 10 particles / mm are added. By forming a second coating layer having a projection of ² to 50 / mm ² and located on the inner side, and setting the average height of the projection from the inner surface of the second coating layer to 5 μm to 40 μm, It is possible to provide a work glove which is excellent and has excellent detachability.

[Table 1]

The roughness of the inner surface of the glove and the removability are related to the average height of the projections and the number per unit area by adding particles to the second coating layer. It can be seen that if the number is in the range of from 40 μm to 40 μm and the number is in the range of from 10 pieces / mm ² to 50 pieces / mm ² , the removability is excellent without roughness. In particular, the detachability when removing the glove is very good as compared with the case where no particles are added as shown in Comparative Example 1. In Comparative Example 2, since the average particle diameter of the added particles is 20 μm, which is smaller than the thickness of the second coating layer, there are few projections appearing on the surface, so that it is not easy to remove. In Comparative Example 3, since the average height of the projections was as high as 50 μm, there was a feeling of roughness, and the projections were caught during mounting. In Comparative Example 4, since the number of convex portions on the surface was small, the feeling of roughness and ease of fitting at the time of mounting were good, but it was not easy to remove. In Comparative Example 5, the average height and the number of convex portions were large, resulting in a feeling of roughness and difficulty in fitting.
