Description

湿式成膜による樹脂皮膜品及びその製造方法Resin film product by wet film formation and method for producing the same
　　本発明は、表面に滑り止めの部分を有する樹脂を有する湿式成膜による樹脂皮膜品及びその製造方法に関するものである。 The present invention relates to a resin film product by wet film formation having a resin having a non-slip portion on the surface and a method for producing the same.
　従来から、滑り性を改善するために手袋の表面に滑り止めを形成する技術がある。例えば溶剤によってゴムを膨潤させ、その後に収縮させることを利用して手袋の表面に凹凸を付けるものがある。しかしながら、滑り止めが、凸状となるため、滑り止め効果があまり発揮できない。 Conventionally, there is a technique for forming a non-slip on the surface of the glove in order to improve the slipperiness. For example, there is a technique in which the surface of a glove is made uneven by utilizing swelling of a rubber with a solvent and then shrinking. However, since the anti-slip becomes convex, the anti-slip effect cannot be exhibited so much.
　また、ゴムラテックスに気泡を含ませることにより、凹状を形成させた滑り止めもあるが、表面は薄い皮膜ができ、凹状部の数が少なくなってしまうことが問題である。 In addition, there is a slipper that forms a concave shape by including bubbles in the rubber latex, but there is a problem that the surface has a thin film and the number of concave portions is reduced.
　それを改善するために、気泡を含ませたゴムラテックスや合成エマルジョンを、ゲル化させる際に表面に粉粒物を付着させ、固化させた後に除去することによって第一の凹状部と第二の凹状部が組み合わされた、滑り止めを形成する方法が提案されている（特許文献１）。 In order to improve it, the rubber latex or synthetic emulsion containing bubbles is adhered to the surface when gelling, solidified and removed after solidification, and then removed from the first concave portion and the second emulsion. There has been proposed a method of forming an anti-slip in which concave portions are combined (Patent Document 1).
　この方法であれば、粉粒物による第一の凹状部の内面に気泡による第二の凹状部が形成されることによって表面積が増大し、滑り止め効果が発揮できる。しかしながら、天然及び、合成樹脂エマルジョンについてのみに行われているのが現状である。 In this method, the surface area is increased by forming the second concave portion due to the bubbles on the inner surface of the first concave portion due to the granular material, and the anti-slip effect can be exhibited. However, the current situation is only for natural and synthetic resin emulsions.

　従来から、ウレタン等の湿式成膜する樹脂の場合、溶剤を含む樹脂から溶剤を取り除くことによってスポンジ状のフィルム膜を形成している。そのため、通気性が良いフィルムになることが知られている。しかしながら、その表面については凹凸になりにくく、水に濡れると滑りやすいことが問題であった。 Conventionally, in the case of a wet film-forming resin such as urethane, a sponge-like film film is formed by removing the solvent from the resin containing the solvent. Therefore, it is known that the film has good air permeability. However, the surface is difficult to be uneven, and the problem is that it is slippery when wet.
　上記のように天然ゴム、合成樹脂エマルジョンにおいては、表面に凹凸を形成する方法が実現化されているが、ウレタン等の湿式成膜する樹脂の場合には、同様な方法では、粉末状固体を付着させて、乾燥固化させると、内部に気泡が出来ず、表面だけの凹凸が出来てしまうために、困難であった。 As described above, in natural rubber and synthetic resin emulsion, a method of forming irregularities on the surface has been realized. However, in the case of a resin for wet film formation such as urethane, a similar method is used to form a powdered solid. When it was made to adhere and dried and solidified, it was difficult because bubbles could not be formed inside and irregularities only on the surface could be made.

この発明の実施例における繊維製手袋の全体構造を示した正面図である。It is the front view which showed the whole structure of the fiber gloves in the Example of this invention. この発明の実施例における繊維製手袋をポリウレタン溶液に浸漬させた状態を示した斜視図である。It is the perspective view which showed the state which immersed the fiber glove in the Example of this invention in the polyurethane solution. この発明の実施例における繊維製手袋にポリウレタン溶液と粉末状固体とを付着させ水に浸漬した状態の一部拡大断面図である。It is a partially expanded sectional view of the state which made the fiber glove in the Example of this invention attach the polyurethane solution and the powdery solid, and was immersed in water. この発明の実施例における手袋から粉末状固体が除去された状態での一部拡大断面図である。It is a partially expanded sectional view in the state from which the powdery solid was removed from the glove in the Example of this invention.
　本実施形態における湿式成膜による樹脂皮膜品は、繊維製生地に、湿式成膜する樹脂をコーティングし、粉末状固体を付着し、その後、湿式成膜すると同時に粉末状固体を除去することにより、その表面に凹凸面を形成したことを特徴としている。 The resin film product by wet film formation in the present embodiment is coated with a resin to be wet film-formed on a fiber fabric, attached with a powdered solid, and then removed by removing the powdered solid simultaneously with the wet film formation. It is characterized in that an uneven surface is formed on the surface.
　ここで、湿式成膜する樹脂とは、水溶性の溶剤に溶かして使用できるものであれば良く、ウレタン樹脂、ナイロン樹脂、塩化ビニル樹脂、アクリル樹脂などの公知の樹脂があり、好ましくは分子量５～１３万のウレタン樹脂がよい。また、これらを混合させたものであっても良い。 Here, the resin for wet film formation may be any resin that can be used by dissolving in a water-soluble solvent, and includes known resins such as urethane resin, nylon resin, vinyl chloride resin, and acrylic resin, and preferably has a molecular weight of 5 ~ 130,000 urethane resin is good. Moreover, what mixed these may be used.
　水溶性の溶剤としては、ＤＭＡＡ（ジメチルアセトアミド）、ＭＥＫ（メチルエチルケトン）等があり、好ましくはＤＭＦ（ジメチルホルムアミド）を用いるとよい。 Examples of the water-soluble solvent include DMAA (dimethylacetamide), MEK (methyl ethyl ketone), etc., preferably DMF (dimethylformamide).
　本発明は、未固化状態の樹脂に粉末状固体を付着し、すぐに上記粉末状固体を除去するようにしている。ここで、粉末状固体とは、特に水溶性のものが良く、例えば塩化ナトリウム、炭酸水素ナトリウム、炭酸ナトリウム、硝酸カルシウム、リン酸ナトリウム、炭酸カルシウムなどの金属塩や、グラニュー糖などの砂糖類、クエン酸、アスコルビン酸などの有機酸等を挙げることができる。また、使用する粉末状固体の粒径によって、凹状部の内径をコントロールすることができる。 In the present invention, a powdery solid is attached to an unsolidified resin and the powdered solid is immediately removed. Here, the powdered solid is particularly preferably water-soluble, for example, metal salts such as sodium chloride, sodium bicarbonate, sodium carbonate, calcium nitrate, sodium phosphate, calcium carbonate, sugars such as granulated sugar, Examples thereof include organic acids such as citric acid and ascorbic acid. Further, the inner diameter of the concave portion can be controlled by the particle size of the powdered solid used.
　また、従来からのエマルジョン樹脂の場合には、粉末状固体を付着し、乾燥固化した後に上記粉末状固体を除去していたが、本実施形態の湿式成膜する樹脂の場合には、樹脂を乾燥固化させると、粉末状固体を取り除くことが困難となり、また、内部が固化してスポンジ状が形成されないという問題があった。 In the case of the conventional emulsion resin, the powdery solid was attached and dried and solidified, and then the powdered solid was removed. When it is dried and solidified, it is difficult to remove the powdery solid, and there is a problem that the inside is solidified and a sponge is not formed.
　そのため、湿式成膜すると同時に粉末状固体を取り除くことが重要であることがわかった。したがって、従来技術に比べると、粉末状固体の付着後に乾燥固化することなしに湿式成膜及び粉末状固体を同時に除去することが大きく異なる点である。 Therefore, it was found that it is important to remove the powdery solid simultaneously with the wet film formation. Therefore, compared with the prior art, the wet film formation and the removal of the powdered solid at the same time without drying and solidifying after the adhesion of the powdered solid are greatly different.
　本発明の対象は、湿式成膜による樹脂皮膜品である。湿式成膜による樹脂皮膜品の具体例としては、手袋、靴下、マット、クッション、敷物、ブルクロース、座布団、枕カバー、鞄、バッグの肩紐、荷造り用ベルト等の他、滑り止め作用を与えるための各種の滑り止め材を挙げることができる。また、ふわふわした感触が得られて肌触りが良いため、内面加工等にも使用できる。 The subject of the present invention is a resin film product by wet film formation. Specific examples of resin film products by wet film formation include gloves, socks, mats, cushions, rugs, burgloose, cushions, pillow covers, bags, shoulder straps for bags, packing belts, etc. Various anti-slip materials can be mentioned. Moreover, since a fluffy feel is obtained and the touch is good, it can be used for inner surface processing and the like.
　さらには、湿式成膜した樹脂部分がスポンジ構造であるため、通気性、断熱性・保温性、防音・防振性を持ち、様々な分野にも応用できる。 Furthermore, since the wet-formed resin part has a sponge structure, it has breathability, heat insulation / heat insulation, soundproofing / vibration resistance, and can be applied to various fields.
　以下、湿式成膜による樹脂皮膜品として、手袋基体の表面に樹脂皮膜を形成したサポートタイプの手袋及びその製造方法を例にとって説明する。 Hereinafter, a support type glove in which a resin film is formed on the surface of a glove base as a resin film product by wet film formation and a manufacturing method thereof will be described as an example.
　なお、湿式成膜する樹脂は、手袋の表面全体に設けてもよいし、部分的に設けてもよい。 The resin for wet film formation may be provided on the entire surface of the glove or may be provided partially.
　また、湿式成膜する樹脂は、繊維製生地の表裏面にも成膜することができる。例えば、手袋の内周面にも湿式成膜する樹脂を成膜することにより、手袋を介して強い力で把持したときの手と手袋との滑りを防止することができる。 Also, the resin for wet film formation can be formed on the front and back surfaces of the fiber fabric. For example, by forming a wet film-forming resin on the inner peripheral surface of the glove, it is possible to prevent the hand and the glove from slipping when gripped with a strong force through the glove.
　編布や織布などの手袋基体を手袋型に装着し、湿式用のウレタン樹脂を塗布し粉末状固体を付着させる。粉末状固体としては水溶性粉末であり、直後に水に浸漬して、水溶性溶剤と粉末状個体を同時に除去するようにしている。その後、十分に乾燥を行うことにより、手袋を作成する。 ¡A glove base such as a knitted fabric or a woven fabric is attached to a glove mold, and a wet urethane resin is applied to adhere a powdered solid. The powdered solid is a water-soluble powder, which is immediately immersed in water to remove the water-soluble solvent and the powdery solid at the same time. Then, the gloves are made by sufficiently drying.
　以下、本発明を実施例により更に詳細に説明するが、本発明はこれらに限定されるものではない。 Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.
　（実施例１）
　本実施例では、手袋作成の場合について説明する。まず、図１に示すように、繊維製生地により、小指部、薬指部、中指部、人差指部を順に編み、これら４つの指部に連続して四本胴部を編み、次いで、親指部を編んで、同親指部と上記四本胴部と連続するように五本胴部を編み、最後に袖部を編み込んで、繊維製手袋１１を形成する。 Example 1
In this embodiment, a case of creating gloves will be described. First, as shown in FIG. 1, with a textile fabric, the little finger part, the ring finger part, the middle finger part, the index finger part are knitted in order, and the four torso parts are knitted continuously to these four finger parts, and then the thumb part is The fiber glove 11 is formed by knitting, knitting the five torso parts so as to be continuous with the thumb part and the four torso parts, and finally knitting the sleeve part.
　次に、図２に示すように、手袋作成型１４に繊維製手袋１１をかぶせ、充填槽１６の中に充填されたポリウレタン溶液１２に浸漬し、ポリウレタン溶液１２を付着させる。ポリウレタン溶液１２は、図２に示すように、繊維製手袋１１の掌部全体に付着させる。ポリウレタン溶液１２から引き揚げたのち、手袋の指先部を下にした状態で垂らすなどして余分な溶液を除去する。 Next, as shown in FIG. 2, the glove making mold 14 is covered with a fiber glove 11 and immersed in the polyurethane solution 12 filled in the filling tank 16 to adhere the polyurethane solution 12. As shown in FIG. 2, the polyurethane solution 12 is attached to the entire palm portion of the fiber glove 11. After pulling up from the polyurethane solution 12, the excess solution is removed by hanging it down with the fingertips of the gloves down.
　ポリウレタン溶液１２は、湿式成膜用ポリウレタン樹脂（固形分３０％）１００重量部、Ｎ，Ｎ’－ジメチルフォルムアミド２００重量部、セル調整剤１重量部及びその他湿式成膜ウレタン樹脂フィルム形成に必要に応じた薬品を混合して作成する。湿式成膜用ポリウレタン樹脂の粘度は５０～５００センチポイズが好ましい。 Polyurethane solution 12 is necessary for forming a wet film-forming urethane resin film, 100 parts by weight of a polyurethane film for wet film formation (solid content 30%), 200 parts by weight of N, N'-dimethylformamide, 1 part by weight of a cell conditioner. Prepare by mixing chemicals according to the conditions. The viscosity of the polyurethane resin for wet film formation is preferably 50 to 500 centipoise.
　次に、繊維製手袋１１に付着したポリウレタン溶液１２部分に、例えば食塩等の粉末状固体を付着させる。すなわち、手袋作成型１４に繊維製手袋１１をかぶせた状態で、水溶性粉末１５を上方からふりかけて、ポリウレタン樹脂部分１３の表面部に水溶性粉末１５を付着させる。 Next, a powdered solid such as salt is adhered to the polyurethane solution 12 portion adhered to the fiber glove 11. That is, in a state where the glove making mold 14 is covered with the fiber glove 11, the water-soluble powder 15 is sprinkled from above to adhere the water-soluble powder 15 to the surface portion of the polyurethane resin portion 13.
　なお、水溶性粉末１５を付着することにより液ダレが止まるので、水溶性粉末１５を付着するタイミングにより、ポリウレタン樹脂の厚みを制御することも可能である。　湿式成膜するポリウレタン樹脂部分１３の厚みは、０．１ｍｍ～２ｍｍであることが好ましい。０．１ｍｍ未満であると、樹脂皮膜が薄いことから手袋本体の保護に欠け、また、２ｍｍを越えると、樹脂皮膜が厚いことから硬くてごわごわした手袋になってしまう。但し、湿式成膜するため、手袋生地にも染み込んで成膜するため、手袋生地が厚い場合には、１ｍｍ以上になることもあり得る。 In addition, since dripping stops by adhering the water-soluble powder 15, it is also possible to control the thickness of the polyurethane resin by the timing of adhering the water-soluble powder 15. The thickness of the polyurethane resin portion 13 to be wet-formed is preferably 0.1 mm to 2 mm. If the thickness is less than 0.1 mm, the protection of the glove body is lacking because the resin film is thin. However, since the wet film formation is performed, the film is soaked in the glove fabric, and therefore, when the glove fabric is thick, the thickness may be 1 mm or more.
　この水溶性粉末１５の付着後、図３に示すように、すぐに繊維製手袋１１を水２０に浸漬させる。水２０に浸漬すると、溶剤としてのジメチルフォルムアミドと水２０との置換作用によりポリウレタン樹脂部分１３がゲル化する。そして、ジメチルフォルムアミドと水２０との置換作用により、ポリウレタン樹脂部分１３に所定大きさの空洞１８が発生する。空洞１８は、図３に示すように、大小異なる大きさを有して複数個が連続したように形成される。 After the water-soluble powder 15 is adhered, the fiber glove 11 is immediately immersed in the water 20 as shown in FIG. When immersed in water 20, the polyurethane resin portion 13 is gelled by the substitution action of dimethylformamide as a solvent and water 20. A cavity 18 having a predetermined size is generated in the polyurethane resin portion 13 by the substitution action of dimethylformamide and water 20. As shown in FIG. 3, the cavities 18 have different sizes and are formed so that a plurality of the cavities 18 are continuous.
　なお、空洞１８の大きさは親水性を調整する添加剤により調整可能であり、上記添加剤を増やせば空洞１８を大きく形成することができる。すなわち、上記添加剤を多く添加することにより、水２０の吸水性が高まり、ジメチルフォルムアミドと水２０との置換が活性されて空洞が大きくなる。しかしながら、空洞が大きくなると、構造が疎になり、強度が弱くなるため、小さい方が好ましい。例えば、空洞の大きさは略数１０μｍ以下である。 The size of the cavity 18 can be adjusted by an additive that adjusts the hydrophilicity. If the additive is increased, the cavity 18 can be formed larger. That is, by adding a large amount of the above additives, the water absorption of the water 20 increases, the substitution of dimethylformamide with the water 20 is activated, and the cavity becomes large. However, when the cavity becomes large, the structure becomes sparse and the strength becomes weak. For example, the size of the cavity is approximately several tens of μm or less.
　また、固形分は、高いほど密になり、低すぎると、粗いスポンジ状となる。そのため、固形分が低すぎると、強度が弱くなるため、５～２０％程度が好ましい。 Also, the higher the solid content, the denser, and if it is too low, it becomes a coarse sponge. Therefore, if the solid content is too low, the strength becomes weak, so about 5 to 20% is preferable.
　また、ジメチルフォルムアミドと水２０との置換作用により、ポリウレタン樹脂部分１３の表面１９は一見フィルム状に平たく形成される。このようにして、繊維製手袋１１の表面にスポンジ状のポリウレタン樹脂部分１３を形成することができる。 Also, the surface 19 of the polyurethane resin portion 13 is formed flat at first glance by a substitution action of dimethylformamide and water 20 at first glance. In this manner, a sponge-like polyurethane resin portion 13 can be formed on the surface of the fiber glove 11.
　また、繊維製手袋１１の表面に付着させた水溶性粉末１５が水２０に溶けるので、図４に示すように、その溶けた部分に凹部１７が生じ、その凹部１７によって容易にポリウレタン樹脂部分１３の表面に凹凸を形成することができる。しかも、凹部１７の内面には満遍なく連続して複数個の空洞１８が形成されている。 Further, since the water-soluble powder 15 attached to the surface of the fiber glove 11 is dissolved in the water 20, as shown in FIG. 4, a concave portion 17 is formed in the melted portion, and the polyurethane resin portion 13 is easily formed by the concave portion 17. Unevenness can be formed on the surface. Moreover, a plurality of cavities 18 are formed uniformly and continuously on the inner surface of the recess 17.
　なお、従来では天然ゴムを使用した場合、乾燥させないでゲル化させたものを水２０につけると未乾燥液が溶け出してしまうことがあるが、湿式成膜する樹脂であるポリウレタン溶液１２を使用した場合には、水２０につけても未乾燥液が溶け出すこともなく、コーティングしたポリウレタン溶液１２は手袋本体から動かない状態となる。 Conventionally, when natural rubber is used, the wet solution may be melted out when the gelatinized without drying is applied to the water 20, but the polyurethane solution 12 which is a resin for wet film formation is used. In such a case, the wet solution does not dissolve even when it is applied to the water 20, and the coated polyurethane solution 12 does not move from the glove body.
　その後、乾燥し、繊維製手袋１１を手袋作成型１４から離型することにより本実施例の手袋の作成を完成させることができる。 Then, drying is performed, and the production of the gloves of this embodiment can be completed by releasing the fiber glove 11 from the glove making mold 14.
　このように、完成させた繊維製手袋１１は、繊維製の生地に、湿式成膜する樹脂をコーティングしており、スポンジ状で表面に凹凸を有する湿式成膜による樹脂皮膜品を得る。このことにより、表面積が大きくなり、優れた滑り止め効果を発揮することができる。また、構造がスポンジ状となり、優れた柔軟性と、優れた通気性、優れた断熱性・保温性、優れた防音・防振性、優れた柔らかな肌触り感を発揮することができる。 As described above, the completed fiber glove 11 is obtained by coating a fiber cloth with a resin for wet film formation, and obtains a resin film product by wet film formation having a sponge shape and unevenness on the surface. As a result, the surface area is increased and an excellent anti-slip effect can be exhibited. In addition, the structure becomes sponge-like, and can exhibit excellent flexibility, excellent breathability, excellent heat insulation and heat retention, excellent sound and vibration insulation, and excellent soft touch.
　本願発明における湿式成膜により形成された樹脂層の方が、従来の天然ゴム・合成樹脂エマルジョンに比べて、表面がやわらかくビロード状であり、クッション材などの製品の保護にも適している。その理由は、従来技術ではゆっくり水分を飛ばすことにより収縮しながら乾燥していくが、本願発明ではＤＭＦを水中で一気に除去するため、微細な空洞ができることによると考えられる。 The resin layer formed by wet film formation in the present invention has a softer and more velvety surface than conventional natural rubber / synthetic resin emulsions, and is suitable for protecting products such as cushioning materials. The reason for this is thought to be that, while the conventional technique dries while shrinking by slowly blowing off moisture, the present invention removes DMF all at once in water, thus forming a fine cavity.
　例えば、本願発明では凹凸の壁の内面にも満遍なく空洞ができており、数１０μｍ以下で小さいものは測定できないほどの微細な構造が形成されている。また、従来技術では固形分が３０－６０％と高いことと、本願発明では固形分が５－２０％と低いことから、固形分の違いもさらに影響していると考えられる。 For example, in the present invention, cavities are evenly formed on the inner surface of the concavo-convex wall, and a fine structure that cannot be measured with a small size of several tens of μm or less is formed. Further, since the solid content is as high as 30 to 60% in the prior art and the solid content is as low as 5 to 20% in the present invention, it is considered that the difference in the solid content is further influenced.
　また、本実施例では、湿式成膜するポリウレタン溶液１２に１回のみ浸漬してコーティングしている。この１回の浸漬により、従来の天然ゴム等の製品に比べて少ない工程で表面にスポンジ状のポリウレタン樹脂部分１３を形成することができる。 Further, in this embodiment, the coating is performed by dipping only once in the polyurethane solution 12 for wet film formation. By this one-time immersion, the sponge-like polyurethane resin portion 13 can be formed on the surface with fewer steps than a conventional product such as natural rubber.
（比較例１）
　次に、手袋作成の場合の比較例１について説明する。比較例１では、上記実施例１と同様に、繊維製手袋を形成した後、手袋作成型１４に繊維製手袋をかぶせ、ポリウレタン溶液に浸漬し、ポリウレタン溶液を付着させる。溶液から引き揚げたのち、手袋の指先部を下にした状態で垂らすなどして余分な溶液を除去する。 (Comparative Example 1)
Next, Comparative Example 1 in the case of creating gloves will be described. In Comparative Example 1, as in Example 1, after forming a fiber glove, the glove making mold 14 is covered with the fiber glove and dipped in a polyurethane solution to adhere the polyurethane solution. After lifting from the solution, remove excess solution by hanging it down with the fingertips of the gloves down.
　次に、繊維製手袋に付着したポリウレタン溶液部分に水溶性粉末を付着させ、７０℃３０分乾燥固化させる。乾燥後、水２０に浸漬し、水溶性粉末を溶解除去する。比較例１では、その後、乾燥し、離型することにより表面に凹凸のある手袋が作成できる。なお、ポリウレタン溶液は、実施例１の場合と同様である。 Next, water-soluble powder is adhered to the polyurethane solution portion adhered to the fiber glove, and dried and solidified at 70 ° C. for 30 minutes. After drying, it is immersed in water 20 to dissolve and remove the water-soluble powder. In Comparative Example 1, a glove having irregularities on the surface can be created by drying and releasing from the mold. The polyurethane solution is the same as in Example 1.
　この方法では、表面には凹凸のある滑り止めが出来たものの、ごわごわとした風合いの悪い手袋となった。これは、粉末状固体を付着した後に乾燥固化することによってポリウレタン樹脂部分１３中のＤＭＦが蒸発して、湿式成膜する前に固化してしまい、十分な空洞ができなかったためである。すなわち、ポリウレタン樹脂部分１３の表面部は、粉末状固体を除去したことによって凹凸となるが、ポリウレタン樹脂部分１３の下層部は固化してしまい、ポリウレタン樹脂部分１３全体がスポンジ状とならずに、上記のようなごわごわした手袋となる。 】 Although this method was able to prevent slipping with irregularities on the surface, it became a glove with a rough texture. This is because the DMF in the polyurethane resin portion 13 is evaporated and solidified before wet film formation by drying and solidifying after adhering the powdery solid, and sufficient cavities were not formed. That is, the surface portion of the polyurethane resin portion 13 becomes uneven due to the removal of the powdered solid, but the lower layer portion of the polyurethane resin portion 13 is solidified, and the entire polyurethane resin portion 13 does not become sponge-like, It becomes such a stiff glove as above.
　以上のことから、本発明の方法よれば、湿式成膜によって出来た空洞によるミクロな構造のスポンジ状の部分と、粉末状固体による、数１００μｍ程度の凹凸が組み合わされた、優れた滑り止め効果を発揮することができると共に、優れた柔軟性と、優れた通気性、優れた断熱性、優れた防音・防振性、優れた柔らかな肌触り感を発揮することができる手袋及びフィルムを作成することが可能であることがわかる。 From the above, according to the method of the present invention, an excellent anti-slip effect in which a microscopic sponge-like portion due to a cavity formed by wet film formation and irregularities of about several hundred μm due to powdered solids are combined. Create gloves and films that can exhibit excellent flexibility, excellent breathability, excellent heat insulation, excellent sound and vibration resistance, and excellent soft touch. It can be seen that it is possible.
　本発明の湿式成膜による樹脂皮膜品は、表面の凹凸によって表面積が広くなるため、滑り止め効果の必要な繊維製生地に使用できる。また、湿式成膜による樹脂皮膜品は、スポンジ状の構造を有するため、通気性、断熱性・保温性、防音・防振性・柔軟性を必要とする用途にも使用できる。さらには、製品を保護する目的として果樹収穫等にも適している。 The resin film product by wet film formation of the present invention has a large surface area due to surface irregularities, and therefore can be used for fiber fabrics that require a non-slip effect. In addition, since the resin film product by wet film formation has a sponge-like structure, it can be used for applications that require air permeability, heat insulation / heat insulation, soundproof / vibration resistance / flexibility. Furthermore, it is also suitable for harvesting fruit trees for the purpose of protecting the product.
