Description
本発明は雨衣、登山衣、スポーツウェア、作業着等の各種衣料用として用いられる透湿防水性能に優れた極細繊維により形成された繊維構造体を有する透湿防水性生地に関するものである。 The present invention relates to a moisture-permeable and waterproof fabric having a fiber structure formed of ultrafine fibers excellent in moisture-permeable and waterproof performance used for various clothes such as rain clothes, mountaineering clothes, sportswear, and work clothes.
透湿性と防水性をあわせもつ透湿防水性の生地は、身体からの発汗による水蒸気を衣服外へ放出する機能と、雨が衣服内に進入するのを防ぐ機能とを有し、スポーツ衣料や防寒衣料等の素材として使用されている。中でも運動に伴う発汗量の比較的多いスポーツやアウトドア、外部での作業のための衣料用素材として多く用いられており、特に、スキー、スノーボード、アスレチック、登山分野においては、今や必要不可欠な衣料素材となっている。 Moisture-permeable and waterproof fabric that combines moisture permeability and waterproofness has the function of releasing water vapor from sweating from the body to the outside of clothes and the function of preventing rain from entering the clothes. Used as a material for winter clothing. In particular, it is widely used as a clothing material for sports, outdoor activities, and outside work, where sweating is relatively high during exercise, and now it is an indispensable clothing material especially in the skiing, snowboarding, athletic and mountaineering fields. It has become.
このような透湿性と防水性をあわせもった生地として、糸を高密度に織り込んだ高密度織物や、ポリウレタン系樹脂やポリエステル系樹脂、ポリテトラフルオロエチレン樹脂等の重合合成体よりなる樹脂膜を、生地片面にコーティングもしくはラミネートの手段で接着したんものが良く知られている。この中でも特に親水性を高めたポリウレタン系樹脂膜を生地片面に接着したものや、微多孔質のポリテトラフルオロエチレン系樹脂やポリウレタン系樹脂により形成された膜を生地片面に形成したものが、防水性、透湿性などの面で評価され、市場に多く受け入れられている。 As a fabric having both moisture permeability and waterproofness, a high-density woven fabric in which yarns are densely woven, and a resin film made of a polymer composite such as polyurethane resin, polyester resin, or polytetrafluoroethylene resin are used. It is well known that it is bonded to one side of the fabric by means of coating or laminating. Among these, those with a polyurethane-based resin film with improved hydrophilicity adhered to one side of the fabric, and those formed with a microporous polytetrafluoroethylene-based resin or polyurethane-based membrane on one side of the fabric are waterproof. It is evaluated in terms of properties and moisture permeability and is widely accepted by the market.
具体的には親水性を高めたポリウレタン系樹脂膜を形成するため、フッ素編成性ポリウレタンと水不溶性、溶媒可溶性ポリアルキレンオキサイド編成物とを配合する方法（例えば特許文献１参照）等が試みられている。しかしながら、かかる透湿棒水膜は、吸水した場合の膜面の膨潤による触感や耐久性に問題があるし、透湿性も十分なものではない。 Specifically, in order to form a polyurethane-based resin film with increased hydrophilicity, a method of blending a fluorine-knitted polyurethane with a water-insoluble, solvent-soluble polyalkylene oxide knitted product (see, for example, Patent Document 1) has been attempted. Yes. However, such a moisture-permeable rod water membrane has a problem in touch and durability due to swelling of the membrane surface when water is absorbed, and the moisture permeability is not sufficient.
また、微多孔質のポリテトラフルオロエチレン膜を積層した透湿防水生地も開示されている（例えば特許文献２参照）。これらは、耐水、透湿共にすぐれた性能を持つが、風合いが堅く、伸縮性が不十分なため、ストレッチ性が要求される生地への応用が難しい。
また、湿式凝固法により微多孔質のポリウレタン膜をコーティングにより直接生地片面に形成する方法（例えば特許文献３参照）や同方法で形成した微多孔質ポリウレタンフィルムを接着する事による、透湿防水性生地を得る方法（例えば特許文献４参照）が発表されている。しかしながら、これらについても、耐水性。透湿性が十分とはいえない。このように、耐水性、透湿性に優れ、更にストレッチ性をも有する透湿防水生地は得られていないのが現状である。
In addition, a method of forming a microporous polyurethane film directly on one side of a fabric by coating by a wet coagulation method (see, for example, Patent Document 3) or a moisture-permeable waterproof property by bonding a microporous polyurethane film formed by the same method A method for obtaining dough (for example, see Patent Document 4) has been announced. However, these are also water resistant. The moisture permeability is not sufficient. Thus, the moisture permeable waterproof fabric which is excellent in water resistance and moisture permeability and also has stretch properties has not been obtained.
本発明はかかる事情を背景として鋭意検討した結果、達成されたものであり、雨衣、登山衣、スポーツウェア、作業着等の各種衣料用として用いられる優れた透湿性と防水性を兼ね備え、なおかつ風合いに優れた透湿防水性生地の提供を課題とするものである。 The present invention has been achieved as a result of diligent investigation against the background of such circumstances, and has excellent moisture permeability and waterproofness used for various clothes such as rain clothes, mountaineering clothes, sportswear, work clothes, and the texture. It is an object of the present invention to provide a moisture-permeable and waterproof fabric excellent in water resistance.
本発明者らは上記課題を解決するために鋭意研究した結果、遂に本発明を完成するに到った。即ち本発明は、（１）平均繊維径０．０１〜１μｍの極細繊維からなる繊維構造が少なくとも１層基材に積層されてなることを特徴とする耐水度が５０ｋＰａ以上であり、透湿性が８０００ｇ／ｍ２・２４ｈｒ以上、通気度が０．２ｃｃ／ｍ２・ｓ以上の透湿防水性生地、（２）前記極細繊維からなる繊維構造体が、厚み２μｍ〜３０μｍ、破断時の伸び率がタテ方向、ヨコ方向共に５０％以上、２０％伸長時のモジュラスがタテ方向、ヨコ方向共に０．７〜３．０Ｎであるであることを特徴とする（１）に記載の透湿防水性生地、（３）前記極細繊維が、ポリウレタン重合体を主体とする重合体から形成されていることを特徴とする（１）又は（２）記載の透湿防水性生地、（４）前記極細繊維からなる繊維構造体が不織布であることを特徴とする（１）〜（３）いずれかに記載の透湿防水性生地、（５）前記極細繊維からなる繊維構造体が荷電紡糸法により形成された事を特徴とする、（１）〜（４）いずれかに記載の透湿防水性生地、（６）前記極細繊維からなる繊維構造体と生地がラミネートにより接着された事を特徴とする（１）〜（５）いずれかに記載の透湿防水性生地、である。 As a result of diligent research to solve the above problems, the present inventors have finally completed the present invention. That is, the present invention is (1) a water structure having an average fiber diameter of 0.01 to 1 μm and laminated with at least one layer base material, and has a water resistance of 50 kPa or more and moisture permeability. 8000 g / m 2 · 24 hr or more, breathable and waterproof fabric with air permeability of 0.2 cc / m 2 · s or more, (2) The fiber structure comprising the ultrafine fibers has a thickness of 2 μm to 30 μm, and the elongation at break is The moisture-permeable and waterproof fabric according to (1), wherein the modulus when stretched by 50% or more in both the vertical and horizontal directions and 20% is 0.7 to 3.0 N in both the vertical and horizontal directions. (3) The moisture-permeable and waterproof fabric according to (1) or (2), wherein the ultrafine fiber is formed from a polymer mainly composed of a polyurethane polymer, and (4) from the ultrafine fiber. The fiber structure is a non-woven fabric (1) to (3) characterized in that the moisture permeable waterproof fabric according to any one of (1) to (3), (5) a fiber structure comprising the ultrafine fibers is formed by a charged spinning method, 4) The moisture-permeable waterproof fabric according to any one of the above, (6) the fiber structure comprising the ultrafine fibers and the fabric bonded together by lamination, and the permeability according to any one of (1) to (5) Moist waterproof fabric.
本発明の透湿防水性生地は、透湿性、防水性に優れ、なおかつ積層体の優れた柔軟性、伸長特性により風合いにも優れた生地である。そのため、雨衣、登山衣、スポーツウェア、作業着等の伸縮性が要求される各種衣料用の生地として、非常に有用である。 The moisture-permeable and waterproof fabric of the present invention is a fabric excellent in moisture permeability and waterproofness, and also excellent in texture due to the excellent flexibility and elongation characteristics of the laminate. Therefore, it is very useful as a fabric for various clothes that require elasticity such as rain clothes, mountaineering clothes, sportswear, work clothes, and the like.
以下本発明を具体的に説明する。
本発明の透湿防水性生地は、平均繊維径０．０１〜１μｍの極細繊維からなる繊維構造が少なくとも１層基材に積層されてなり、耐水度が５０ｋＰａ以上であり、透湿性が８０００ｇ／ｍ２・２４ｈｒ以上、通気度が０．２ｃｃ／ｍ２・ｓ以上の透湿防水性生地であることが好ましい。耐水圧が５０ｋＰａ以上であれば、実用上十分な防水性能が確保できる。また、透湿性は８０００ｇ／ｍ２・２４ｈ以上、通気度０．３ｃｃ／ｍ２・ｓ以上であれば衣服として着用して活動時している状態での快適性が高くなる。特に、低発汗時の快適性への効果が大きい。そして、実質的に、透湿防水性を発揮する極細繊維構造体が、平均繊維径０．０１〜１μｍの極細繊維から構成されることにより、透湿防水性を発現する微細孔を形成することができる一方で、従来の透湿防水膜に比して、風合いが格段に向上し、更に欠点の伝播がし難いため実用時の使用期間が延長されるという有利な効果も発揮する。より好ましい平均繊維径は０．０５〜０．８μｍ、更に好ましくは０．１μｍ〜０．５μｍである。
The present invention will be specifically described below.
The moisture permeable and waterproof fabric of the present invention is formed by laminating a fiber structure composed of ultrafine fibers having an average fiber diameter of 0.01 to 1 μm on at least one layer base material, having a water resistance of 50 kPa or more and a moisture permeability of 8000 g / It is preferably a moisture-permeable and waterproof fabric having an air permeability of 0.2 cc / m 2 · s or more and m 2 · 24 hours or more. If the water pressure resistance is 50 kPa or more, practically sufficient waterproof performance can be secured. In addition, if the moisture permeability is 8000 g / m 2 · 24 h or more and the air permeability is 0.3 cc / m 2 · s or more, the comfort in the state of being worn as clothes and active is increased. In particular, the effect on comfort when sweating is low. And the micropore which expresses moisture permeability waterproofness is formed substantially by the ultrafine fiber structure which exhibits moisture permeability waterproofness being comprised from ultrafine fiber with an average fiber diameter of 0.01-1 micrometer. On the other hand, as compared with the conventional moisture-permeable waterproof membrane, the texture is remarkably improved, and further, it is difficult to propagate the defects, so that the useful period of use is extended. A more preferable average fiber diameter is 0.05 to 0.8 μm, still more preferably 0.1 μm to 0.5 μm.
耐水度は、膜厚の調整により上げる事は出来るが、風合いが堅くなる。また耐水度を上げると透湿性、通気性も下がる傾向である。その点も含めて考慮すると、耐水度は５００ｋＰａ以下である事がより望ましい。 The water resistance can be increased by adjusting the film thickness, but the texture becomes stiff. Further, when the water resistance is increased, moisture permeability and air permeability tend to decrease. Taking this point into consideration, the water resistance is more preferably 500 kPa or less.
本発明の透湿防水性基布は、前記極細繊維からなる繊維構造体が、厚みが２μｍ〜３０μｍ、破断時の伸び率がタテ方向、ヨコ方向共に５０％以上、２０％伸長時のモジュラスがタテ方向、ヨコ方向共に０．７〜３．０Ｎであるであることが好ましい。かかる範囲であれば、加工性、実用上必要とされる耐水性・透湿性・強度を損なうことなく、優れた着用時の快適性、特にストレッチ性のある生地が得られるからである。より望ましくはタテ方向、ヨコ方向共に伸度６０％以上、厚み３μｍ〜２５μｍである。 The moisture permeable and waterproof base fabric of the present invention has a fiber structure composed of the ultrafine fibers having a thickness of 2 μm to 30 μm, an elongation at break of 50% or more in both the vertical and horizontal directions, and a modulus at 20% elongation. It is preferable that it is 0.7-3.0N in a length direction and a horizontal direction. This is because, within such a range, excellent wear comfort, particularly a stretchable fabric can be obtained without impairing the workability, water resistance, moisture permeability and strength required for practical use. More preferably, the elongation is 60% or more in both the vertical direction and the horizontal direction, and the thickness is 3 μm to 25 μm.
本発明の透湿防水性生地に用いる上記極細繊維からなる繊維構造体の素材としては、ポリウレタン系重合体、ポリエステル系重合体、ポリアミド系重合体、アクリル系重合体、シリコン系重合体、ポリオレフィン系重合体、ポリイミド系重合体などが挙げられる。物理特性や水分特性、柔軟性を考慮に入れると、ポリウレタン系重合体がより望ましい。 Examples of the material of the fiber structure composed of the above-mentioned ultrafine fibers used in the moisture-permeable and waterproof fabric of the present invention include a polyurethane polymer, a polyester polymer, a polyamide polymer, an acrylic polymer, a silicon polymer, and a polyolefin polymer. A polymer, a polyimide-type polymer, etc. are mentioned. In consideration of physical properties, moisture properties, and flexibility, polyurethane polymers are more desirable.
本発明の透湿防水性生地に用いる上記繊維構造体の具体的形態としては、編物、織物、不織布の形態が挙げられるが、特に不織布であることが好ましい。不織布であれば、３次元的に微細孔を形成し、柔軟性、風合いにも優れるからである。 Specific examples of the fiber structure used in the moisture-permeable and waterproof fabric of the present invention include knitted fabrics, woven fabrics, and nonwoven fabrics, with nonwoven fabrics being particularly preferred. This is because if it is a non-woven fabric, fine holes are formed three-dimensionally and the flexibility and texture are excellent.
本発明の透湿防水性生地に用いる上記繊維構造体の製造方法は特に限定されるものではないが、荷電紡糸法により紡糸することが好ましい。この方法により従来では製造出来なかったナノサイズの直径の繊維が作る事が可能である。この極細繊維を厚み方向に積層させる事により、防水性、透湿性に優れなおかつ、伸長性にも優れた多孔質積層体を作る事が出来る。これらの多孔質積層体は従来の多孔質膜に比べ、優れた耐水性、透湿性に加え、通気性も得る事が可能である。
複合紡糸法などによりえられた糸を不織布状に積層し、マトリクス層の洗浄処理や割線処理をする事によっても同様の積層体の製造は可能であるが、複雑な工程となり、非常に煩雑でなおかつ高コストとなり、コスト面においても、荷電紡糸法は有利な製造方法である。
Although the manufacturing method of the said fiber structure used for the moisture-permeable waterproof fabric of this invention is not specifically limited, It is preferable to spin by a charge spinning method. With this method, it is possible to produce nano-sized fibers that could not be produced conventionally. By laminating these ultrafine fibers in the thickness direction, a porous laminate having excellent waterproofness and moisture permeability and excellent extensibility can be produced. These porous laminates can obtain air permeability in addition to excellent water resistance and moisture permeability as compared with conventional porous membranes.
It is possible to manufacture the same laminate by laminating the yarn obtained by the composite spinning method into a non-woven fabric, and subjecting the matrix layer to a cleaning process or a split line process, but this is a complicated process and is very complicated. In addition, the cost spinning method is also an advantageous manufacturing method in terms of cost.
また、荷電紡糸法により積層表面に位置する極細繊維がランダムに配向される事により、ポリウレタンの様な粘弾性の高いポリマーの積層体にもかかわらず、表面のタッチがべたつかず滑らかになる効果も確認される。これらの事からも荷電紡糸により形成されたものの方が透湿防水性生地用の積層体としては望ましい。 In addition, the ultrafine fibers located on the surface of the laminate are randomly oriented by the charge spinning method, so that the touch of the surface is not sticky and smooth despite the laminate of polymers with high viscoelasticity such as polyurethane. It is confirmed. Also from these things, the one formed by charge spinning is preferable as a laminate for moisture-permeable and waterproof fabric.
荷電紡糸による積層体の場合、積層状態によっては、摩擦耐久性に劣る場合があるが、その場合においても、積層体を熱プレス処理することにより、改善する事が可能である。この工程は、積層体の状態で行っても良いし、生地に接着させた後に行ってもよい。 In the case of a laminate by charge spinning, depending on the lamination state, the friction durability may be inferior, but even in that case, it can be improved by subjecting the laminate to a hot press treatment. This process may be performed in the state of a laminated body, or may be performed after bonding to the fabric.
本発明の透湿防水性生地に用いる上記極細繊維からなる繊維構造体と基材とはラミネート工程により接着される事が望ましい。接着剤をフィルム面に、全面もしくは、グラビア法やロータリー捺染法などにより非全面に均一に塗布し、生地と圧着させ接着する方法がある。極細繊維により形成された繊維構造体の特徴をより生かすためには、接着剤を非全面に均一に塗布した方法を用いる方が、透湿性や風合い面からも望ましい。例えばドット状、格子状に接着剤を塗布することが望ましい。 It is desirable that the fiber structure composed of the ultrafine fibers used in the moisture-permeable and waterproof fabric of the present invention and the substrate are bonded together by a laminating process. There is a method in which an adhesive is uniformly applied to the entire surface of the film or a non-overall surface by a gravure method, a rotary printing method, or the like, and is bonded to the fabric by pressure bonding. In order to make better use of the characteristics of the fiber structure formed of ultrafine fibers, it is desirable from the viewpoint of moisture permeability and texture to use a method in which an adhesive is uniformly applied to the entire surface. For example, it is desirable to apply an adhesive in a dot shape or a lattice shape.
また、極細繊維からなる繊維構造体を接着した後に使用時の耐久性向上の目的で、生地を貼り付けても良い。生地としては、薄地のトリコットや薄地織物が厚みもあがらず、縫製時のシームテープ処理などが行いやすく望ましい。また、同様の目的で、ナノファイバー積層体面に、透湿性ウレタン等によるトップコート層を乗せたり、柄状にウレタンプリントを行ってもよい。 Moreover, you may affix a cloth | dough for the purpose of the durability improvement at the time of use, after adhere | attaching the fiber structure which consists of an ultrafine fiber. As the fabric, a thin tricot or a thin woven fabric does not increase in thickness, and it is easy to perform seam tape processing at the time of sewing. For the same purpose, a top coat layer made of moisture-permeable urethane or the like may be placed on the surface of the nanofiber laminate, or urethane printing may be performed in a pattern.
本発明により得られた透湿防水性生地は防水性を向上する目的で撥水加工を施していても良い。この工程は、生地の段階で行っても良いし、生地にナノファイバーを接着させた後に行ってもよい。 The moisture-permeable and waterproof fabric obtained by the present invention may be subjected to water repellent treatment for the purpose of improving waterproofness. This step may be performed at the fabric stage or after the nanofibers are bonded to the fabric.
本発明の透湿防水性生地に用いる基材としては、織物でも丸編みや経編みの様なニットでもかまわない。織物の場合従来使用されている、透湿防水用の布帛同様、強力や摩耗性に優れた製品を得る事が出来る。また、ニットの場合、素材の持つ伸長性やソフト風合いを損なう事無く、透湿防水性を得る事ができる。 The substrate used in the moisture-permeable and waterproof fabric of the present invention may be woven fabric or knit such as circular knitting or warp knitting. In the case of a woven fabric, it is possible to obtain a product excellent in strength and abrasion as in the case of a moisture permeable and waterproof fabric conventionally used. In the case of knitwear, moisture permeability and waterproofness can be obtained without impairing the stretchability and soft texture of the material.
本発明に用いる基材の素材としては、合成繊維でも天然繊維でもかまわない。生地としての防水性能を考慮すると、合成繊維主体の生地の方が望ましい。合成繊維としては、ポリエチレンテレフタレート、ポリトリメチレンテレフタレート、ポリブチレンテレフタレートなどのポリエステル繊維、ナイロン６、ナイロン６６、などのポリアミド繊維、アクリル繊維、ポリプロピレン、ポリエチレンなどのポリオレフィン繊維、ポリウレタン繊維、ポリイミド繊維などが考えられる。これらの単独もしくは組み合わせにより、作られた生地があげられる。 The base material used in the present invention may be synthetic fiber or natural fiber. Considering the waterproof performance as a fabric, a fabric mainly composed of synthetic fibers is preferable. Synthetic fibers include polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate and polybutylene terephthalate, polyamide fibers such as nylon 6 and nylon 66, polyolefin fibers such as acrylic fiber, polypropylene and polyethylene, polyurethane fibers and polyimide fibers. Conceivable. The dough made by these alone or in combination is raised.
