Abstract
Description
本発明は、衣料用素材に適したポリアミド系高密度編地に関する。 The present invention relates to a polyamide-based high-density knitted fabric suitable for clothing materials.
衣料用素材は年々市場のニーズと素材の組み合わせが非常に複雑になってきている分野である。なかでもアウター用衣料に関しては古くから歴史があり、防風性を重視したラミネート素材や樹脂コーティング素材が広く知られ、高密度繊維構造物で透湿性や防風性に感性も重視する素材へと発展している。
例えば、ポリアミド系繊維を用いた平織物を１０％以上収縮させて、防水・透湿性を有する高密度繊維構造物が提案されている（特許文献１参照）。また、単糸繊度の異なるマルチフィラメントからなる複合糸を用いた、防風機能・撥水機能を兼ね備えた高密度編地が提案されている（特許文献２参照）。また、編地に樹脂コートすることにより、ダウンの吹き出しを防止するとともに、防風性能を兼ね備えたストレッチコート編地が提案されている（特許文献３参照）。
また、近年は着用時の快適性や取扱いの容易さからストレッチ性を有する素材が非常に注目されており、スポーツなどの体を動かす分野以外にも大きな広がりを見せている。
Clothing materials are an area where market needs and material combinations are becoming extremely complex year by year. Among them, outerwear has a long history, and laminated materials and resin coating materials that emphasize wind resistance are widely known, and have developed into materials that emphasize moisture permeability and wind resistance as well as high-density fiber structures. ing.
For example, a high-density fiber structure having waterproof and breathable properties by shrinking a plain woven fabric using a polyamide fiber by 10% or more has been proposed (see Patent Document 1). Further, a high-density knitted fabric having both a windproof function and a water-repellent function using a composite yarn made of multifilaments having different single yarn fineness has been proposed (see Patent Document 2). Further, a stretch-coated knitted fabric has been proposed in which the knitted fabric is coated with a resin to prevent down blowout and also has windproof performance (see Patent Document 3).
In recent years, stretchable materials have attracted a great deal of attention because of their comfort when worn and ease of handling, and they are expanding widely beyond the fields of physical activity such as sports.
しかしながら、アウター素材に関しては、防風性や耐水性の観点から緻密な構造が求められるため、上記のような、ラミネート素材や樹脂コーティング素材の２次加工素材や高密度化した織物が中心であり、編物ではまだ満足のいく素材が得られていない。その理由は、１つは編物の基本構造がループ構造であるからである。編物はこのループ構造が３次元的に重なり形成しているため、直線構造が基本である織物のように緻密な高密度素材とするのが難しい。一部には高密度化した編物も存在するが、高密度化により防風性や耐水性は得られるものの、ストレッチ性のない布帛となる。現在編地単体でストレッチ性と高密度化が両立された素材は非常に難しく、ラミネート加工や樹脂コーティング加工の２次加工を含んだものづくりが中心である（特許文献３参照）。
したがって、本発明は、上記のような問題を解消し、防風性、耐水性、透湿性に優れながら、ストレッチ性を有する衣料用素材に適したポリアミド系高密度編地を提供することをその目的とする。
However, as for outer materials, a precise structure is required from the viewpoint of wind resistance and water resistance, so the above-mentioned secondary processing materials such as laminate materials and resin coating materials and high-density woven fabrics are the main products. Knitting has not yet provided satisfactory materials. One reason is that the basic structure of knitting is a loop structure. Since this loop structure is three-dimensionally overlapped and formed in a knitted fabric, it is difficult to make a dense high-density material like a woven fabric which is basically a linear structure. Some knitted fabrics have a high density, and although the high density provides wind resistance and water resistance, the fabric does not have stretchability. At present, it is extremely difficult to make a knitted fabric that has both stretchability and high density, and the focus is on manufacturing that includes secondary processing such as laminating and resin coating (see Patent Document 3).
Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a polyamide-based high-density knitted fabric suitable for a clothing material having stretchability while being excellent in wind resistance, water resistance, and moisture permeability. And.
本発明の目的は、ポリアミド系繊維を用いた経編物であり、下記物性を同時に満足することを特徴とするポリアミド系高密度編物によって達成される。
（１）通気度が、２０ｃｃ／ｃｍ２・秒以下
（２）耐水度が、２５０ｍｍＨ２Ｏ／ｃｍ２以上
（３）透湿度が、６０００ｇ／ｍ２・２４ｈ以上
（４）伸長率が、タテ方向・ヨコ方向ともに５％以上である
An object of the present invention is a warp knit using polyamide fibers, which is achieved by a polyamide high-density knit characterized by simultaneously satisfying the following physical properties.
(1) air permeability, 20 cc / cm 2 · sec or less (2) water resistance is, 250mmH 2 O / cm 2 or more (3) moisture permeability, 6000 g / m 2 · 24h or more (4) stretch ratio of, vertical 5% or more in both direction and horizontal direction
また、本発明は、剛軟度が、タテ方向・ヨコ方向ともに１０〜８０ｍｍであることが好ましい。
また、本発明は、編目密度が、４０００個／ｉｎｃｈ２（（２．５４ｃｍ）２）以上であることが好ましい。
Further, in the present invention, the rigidity and softness are preferably 10 to 80 mm in both the vertical direction and the horizontal direction.
Further, in the present invention, the stitch density is preferably 4000 stitches / inch 2 ((2.54 cm) 2 ) or more.
本発明のポリアミド系高密度編物は、防風性、耐水性、透湿性に優れながら、ストレッチ性のある衣料用素材に適した高密度編物である。 The polyamide-based high-density knitting of the present invention is a high-density knitting material that is excellent in wind resistance, water resistance, and moisture permeability, and is suitable for a stretchable clothing material.
以下、本発明を詳細に説明する。
本発明のポリアミド系高密度編地は、ポリアミド系繊維を用いて編成された経編地であり、特定の通気度、耐水度、透湿度及び伸長率を有する。本発明のポリアミド系高密度編地は、編地に含まれるポリアミド系繊維への膨潤・収縮処理を行い、必要に応じて撥水加工を施した編地である。
Hereinafter, the present invention will be described in detail.
The polyamide-based high-density knitted fabric of the present invention is a warp knitted fabric knitted using polyamide-based fibers, and has specific air permeability, water resistance, moisture permeability, and elongation. The polyamide-based high-density knitted fabric of the present invention is a knitted fabric in which the polyamide-based fibers contained in the knitted fabric are swelled and shrunk, and if necessary, water-repellent.
本発明に用いるポリアミド系繊維は、ポリアミド繊維または複合繊維が挙げられる。
ポリアミド繊維とは主鎖の繰り返し単位中にアミド結合を有する重合体で、熱可塑性樹脂であるものをさす。ここでポリアミド繊維としては、例えば、ナイロン４、ナイロン６、ナイロン７、ナイロン１１、ナイロン１２、ナイロン６６、ナイロン６．１０、ポリメタキシレンアジパミド、ポリパラキシリレンデカンアミド、ポリビスシクロヘキシルメタンデカンアミド等及びそれらを成分とするコポリアミド等のポリマーからなる繊維が挙げられる。好ましくは、６ナイロンや６６ナイロン繊維がよい。また、風合いや緻密性を求める点からハイマルチのフィラメントであることが望ましい。
さらに、単糸繊度についても風合いや緻密性を求める点から好ましくは２．５ｄｔｅｘ以下であり、さらに好ましくは１．５ｄｔｅｘ以下である。
また、総繊度は、１１〜１１０ｄｔｅｘが好ましい。総繊度が細いと生地の強度が低下する恐れがあり、総繊度が太いと編立時に編針への負荷が大きく操業性を阻害する恐れがある。さらに好ましくは２２〜８４ｄｔｅｘである。
Examples of the polyamide fiber used in the present invention include polyamide fiber and composite fiber.
Polyamide fiber is a polymer having an amide bond in the repeating unit of the main chain, and refers to a thermoplastic resin. Here, examples of the polyamide fiber include nylon 4, nylon 6, nylon 7, nylon 11, nylon 12, nylon 66, nylon 6.10, polymethoxylen adipamide, polyparaxylylene decaneamide, and polybiscyclohexylmethane. Examples thereof include fibers made of decaneamide and the like and polymers such as copolyamide containing them as components. Preferably, 6 nylon or 66 nylon fibers are preferable. Further, it is desirable to use a high-multi filament from the viewpoint of obtaining texture and fineness.
Further, the single yarn fineness is preferably 2.5 dtex or less, and more preferably 1.5 dtex or less from the viewpoint of obtaining texture and fineness.
The total fineness is preferably 11 to 110 dtex. If the total fineness is small, the strength of the fabric may decrease, and if the total fineness is large, the load on the knitting needle may be large during knitting and the operability may be impaired. More preferably, it is 22 to 84 dtex.
本発明に用いる複合繊維は、コンジュゲートファイバ（ＪＩＳ用語にも記載）をさす。詳しくは性質の異なる２種類以上のポリマーを口金で複合した繊維である。本発明においては、ポリアミド系複合繊維として、ポリアミドとポリエステルとの組合せからなるポリアミド系複合繊維が好適である。
ポリアミドとしては、前記ポリマーが挙げられ、ポリエステルとしては、後記ポリエステル繊維に使用されるポリマーが挙げられる。なお、ポリエステルは、水またはアルカリ溶液により溶解しないポリマーが好ましい。
The composite fiber used in the present invention refers to a conjugated fiber (also described in JIS terminology). Specifically, it is a fiber in which two or more types of polymers having different properties are composited with a base. In the present invention, as the polyamide-based composite fiber, a polyamide-based composite fiber composed of a combination of polyamide and polyester is suitable.
Examples of the polyamide include the above-mentioned polymer, and examples of the polyester include the polymer used for the polyester fiber described later. The polyester is preferably a polymer that is insoluble in water or an alkaline solution.
具体的にはポリアミド及びポリエステルが、単一フィラメントの横断面において一方の成分が他方の成分を完全に包囲しない形状で、単一フィラメントの長手方向に沿って接合されているものをいい、具体的には横断面が、サイドバイサイド型の複合繊維、サイドバイサイド繰り返し型の複合繊維、放射型の形状を有する成分と該放射部を補完する形状を有する他の成分からなる複合繊維、放射型の形状を有する成分と該放射部を補完し且つ中心方向に向いたＶ字型の凹部のある形状を有する他の成分と該凹部を補完するＶ字型の形状を有する成分と同じ成分からなる複合繊維、中空部分のあるサイドバイサイド繰り返し型複合繊維等が挙げられる。これらの複合繊維のうち、単糸繊度が０．５ｄｔｅｘ以下の極細フィブリルが得易いという点から、中空部分のある又はないサイドバイサイド繰り返し型の横断面を有する複合繊維、及び横断面が放射型の形状を有する成分のある複合繊維が好適であり、複合繊維製造面では両者の内、繊維断面形態の安定性の点から横断面が放射型の形状を有する成分のある複合繊維が有利である。 Specifically, polyamide and polyester are joined along the longitudinal direction of the single filament in a shape in which one component does not completely surround the other component in the cross section of the single filament. Has a side-by-side type composite fiber, a side-by-side repeating type composite fiber, a composite fiber composed of a component having a radial shape and another component having a shape complementary to the radial portion, and a radial shape. A composite fiber composed of a component, another component having a V-shaped recess that complements the radiating portion and a V-shaped recess facing the center, and the same component as the component having a V-shape that complements the recess, hollow. Examples thereof include side-by-side repeating type composite fibers having a portion. Among these composite fibers, a composite fiber having a side-by-side repeating cross section with or without a hollow portion and a shape having a radial cross section are available because it is easy to obtain ultrafine fibrils having a single yarn fineness of 0.5 dtex or less. A composite fiber having a component having a cross section is preferable, and among the two, a composite fiber having a component having a radial cross section is advantageous from the viewpoint of stability of the fiber cross-sectional morphology.
前記の通り、ポリアミド系複合繊維は、フィブリル化後の単糸繊度が、０．５ｄｔｅｘ以下であることが好ましい。
また、総繊度は、１１〜１１０ｄｔｅｘが好ましい。総繊度が細いと生地の強度が低下する恐れがあり、総繊度が太いと編立時に編針への負荷が大きく操業性を阻害する恐れがある。さらに好ましくは３３〜８４ｄｔｅｘである。
As described above, the polyamide-based composite fiber preferably has a single yarn fineness of 0.5 dtex or less after fibrillation.
The total fineness is preferably 11 to 110 dtex. If the total fineness is small, the strength of the fabric may decrease, and if the total fineness is large, the load on the knitting needle may be large during knitting and the operability may be impaired. More preferably, it is 33 to 84 dtex.
前記ポリアミド繊維や複合繊維は長繊維が好適である。合成繊維を短繊維にすることはコストがかかり、編地編成時に風綿の懸念もあるため、長繊維であることが望ましい。 Long fibers are preferable as the polyamide fibers and composite fibers. It is desirable to use long fibers because it is costly to make synthetic fibers short fibers and there is a concern about wind cotton when knitting the knitted fabric.
本発明の高密度編物に含まれるポリアミド系繊維の混率は１５質量％以上とする事が好ましい。本発明では編地を編成したのち、ポリアミド系繊維への膨潤・収縮処理を行う。ここで編地に対しポリアミド系繊維の混率が１５質量％未満の場合には、ポリアミド系繊維の膨潤・収縮処理による高密度化が低下する恐れがある。一方でポリアミド系繊維が高混率の場合は、ポリアミド系繊維への膨潤・収縮処理を行うと非常に高密度化した布帛が得られやすくなる。ポリアミド系繊維の混率に関し、好ましくは２５質量％以上であり、さらに好ましくは５０質量％以上、ストレッチ性が維持されるのであれば１００質量％でも問題はない。 The mixing ratio of the polyamide fibers contained in the high-density knitted fabric of the present invention is preferably 15% by mass or more. In the present invention, after knitting the knitted fabric, swelling / shrinking treatment is performed on the polyamide fiber. Here, when the mixing ratio of the polyamide fibers with respect to the knitted fabric is less than 15% by mass, the density increase due to the swelling / shrinking treatment of the polyamide fibers may decrease. On the other hand, when the polyamide fiber has a high mixing ratio, it is easy to obtain a very high-density fabric by performing the swelling / shrinking treatment on the polyamide fiber. Regarding the mixing ratio of the polyamide fibers, it is preferably 25% by mass or more, more preferably 50% by mass or more, and 100% by mass as long as the stretchability is maintained.
ポリアミド系繊維の混率が１５質量％以上の高密度編物とするにあたって、使用するポリアミド系繊維は、ポリアミド繊維のみまたはポリアミド系複合繊維のみ、またはこれらを組合せてもよく、特に、両者を組合せると、編地の長さ方向・幅方向・厚み方向にポリアミド系繊維が配置された編地が形成されるため、より安定した高密度編物を得やすくなる点で好適である。 In order to prepare a high-density knitted fabric in which the mixing ratio of the polyamide fibers is 15% by mass or more, the polyamide fibers used may be only the polyamide fibers or only the polyamide-based composite fibers, or a combination thereof, and in particular, when both are combined. Since the knitted fabric in which the polyamide fibers are arranged in the length direction, the width direction, and the thickness direction of the knitted fabric is formed, it is preferable in that a more stable high-density knitted fabric can be easily obtained.
また、本発明の目的を損なわない範囲で、ポリアミド系繊維に、ポリエステル系繊維を組合せてもよい。本発明に用いるポリエステル系繊維は、主鎖の繰り返し単位中にエステル結合を有する重合体で、熱可塑性樹脂であるものをさす。ここでポリエステル系繊維としては、例えば、ポリエチレンテレフタレート、ポリテトラメチレンテレフタレート、ポリエチレンオキシベンゾェート、ポリ１，４−ジメチルシクロヘキサンテレフタレート、ポリピバロラクトン等及びこれらを成分とするコポリエステル等のポリマーからなる繊維が挙げられる。 Further, a polyester fiber may be combined with the polyamide fiber as long as the object of the present invention is not impaired. The polyester fiber used in the present invention refers to a polymer having an ester bond in the repeating unit of the main chain, which is a thermoplastic resin. Here, the polyester fiber is made of, for example, a polymer such as polyethylene terephthalate, polytetramethylene terephthalate, polyethylene oxybenzoate, poly 1,4-dimethylcyclohexane terephthalate, polypivalolactone, and copolyester containing these. Fiber is mentioned.
その形態は、単成分繊維、複合繊維等いずれでもよい。また、その形態は、短繊維、長繊維のいずれでもよい。前記のポリアミド系繊維の場合と同様に、合成繊維で短繊維にすることはコストがかかり、編地編成時に風綿の懸念もあるため、長繊維であることが望ましい。 The form may be either a single component fiber, a composite fiber or the like. Further, the form may be either short fiber or long fiber. As in the case of the above-mentioned polyamide fiber, it is costly to make a short fiber with a synthetic fiber, and there is a concern about wind cotton during knitting, so a long fiber is desirable.
本発明のポリアミド系高密度編地は、経編地である。編物はループの連結によって形成された生地であり、編目を形成する方向の違いから経編と緯編に区分することができる。同一糸で見た場合、経編では編目がタテ方向（生地の長さ方向）に形成され、緯編は編目がヨコ方向（生地の幅方向）に形成される。さらに詳しくは、経編では編目を形成する際にタテ方向に移動すると同時にヨコ方向（生地の幅方向）にも編目位置を移動することが可能であるのに対し、緯編（特に丸編）では編目形成はヨコ方向がメインとなる。緯編（特に丸編）でもタック編を利用することでタテ方向（生地の長さ方向）へ同一糸を移動させ生地を形成するは可能であるが、構成される糸の繊度や編機設備により組織の制限があり、また形成する編地の表面感に凹凸が生まれやすい。生地の品位や機能性である防風性、耐水性、透湿性、ストレッチ性を得るには、編地を形成する段階でループの連結をしながら糸同士が３次元的に絡み合う構造を取っていることが望ましく、緯編地よりも経編地の方が優れている。 The polyamide-based high-density knitted fabric of the present invention is a warp knitted fabric. A knitted fabric is a fabric formed by connecting loops, and can be classified into a warp knit and a weft knit according to the difference in the direction in which the stitches are formed. When viewed with the same yarn, in the warp knitting, the stitches are formed in the vertical direction (the length direction of the fabric), and in the weft knitting, the stitches are formed in the horizontal direction (the width direction of the fabric). More specifically, in warp knitting, it is possible to move the stitch position in the horizontal direction (width direction of the fabric) at the same time as moving in the vertical direction when forming the stitch, whereas in the weft knitting (especially the circular knitting). Then, the stitch formation is mainly in the horizontal direction. Even in weft knitting (especially circular knitting), it is possible to move the same yarn in the vertical direction (the length direction of the fabric) to form the fabric by using the tuck knitting, but the fineness of the yarn to be composed and the knitting machine equipment As a result, the structure is restricted, and the surface texture of the knitted fabric to be formed tends to be uneven. In order to obtain the quality and functionality of the fabric, such as windproof, water resistant, breathable, and stretchable, the yarns are three-dimensionally entwined while connecting the loops at the stage of forming the knitted fabric. It is desirable that the warp knitted fabric is superior to the weft knitted fabric.
また、編機については、２８ゲージ以上のハイゲージ編機を使用し、編成することが好ましい。これは目標の編地の諸物性が向上するためである。すなわち２８ゲージ未満の編機を使用して編み立てた場合には、生機の編目密度が小さくなり、ポリアミド系高密度編地を得ることが困難となる。具体的には目標とする通気度やストレッチ性が得られない。このため、好ましくは２８ゲージ以上、さらに好ましくは３２ゲージ以上で編立を行う事が好ましい。 As for the knitting machine, it is preferable to use a high gauge knitting machine of 28 gauge or more for knitting. This is because the physical properties of the target knitted fabric are improved. That is, when knitting is performed using a knitting machine of less than 28 gauge, the stitch density of the raw machine becomes small, and it becomes difficult to obtain a polyamide-based high-density knitted fabric. Specifically, the target air permeability and stretchability cannot be obtained. Therefore, it is preferable to perform knitting with a gauge of 28 gauge or more, more preferably 32 gauge or more.
本発明で用いるポリアミドの膨潤剤としては、ベンジルアルコール、フェノール、ギ酸、酢酸、ジメチルホルムアミド、キシレン等のエマルジョンが挙げられ、特にベンジルアルコールのエマルジョンが好ましい。また安定したエマルジョンを維持するため乳化剤を併用するのが好ましい。 Examples of the polyamide swelling agent used in the present invention include emulsions of benzyl alcohol, phenol, formic acid, acetic acid, dimethylformamide, xylene and the like, and emulsions of benzyl alcohol are particularly preferable. Further, it is preferable to use an emulsifier together in order to maintain a stable emulsion.
また、本発明で行うポリアミド系繊維への膨潤・収縮加工については、１００℃以下で行う事が好ましい。膨潤・収縮加工ではポリアミド系繊維に対し、膨潤剤を付与することでポリアミド系繊維は膨潤し、熱が加えられることで繊維自体が収縮する。この際、同一濃度の膨潤剤を使用した場合、温度が高くなるに従い、膨潤と収縮の度合いが大きくなり、高密度化しやすくなる。一方でポリアミド系繊維が溶解するため、従来備えていた繊維としての強度や伸度が低下する。そのため高密度化させながらも繊維としての諸物性を維持することが必要であり、温度が１００℃以下で行う事が望ましく、好ましくは９０℃以下であり、さらに好ましくは８０℃以下である。 Further, the swelling / shrinking processing of the polyamide fiber performed in the present invention is preferably performed at 100 ° C. or lower. In the swelling / shrinking process, the polyamide fiber is swelled by applying a swelling agent to the polyamide fiber, and the fiber itself contracts when heat is applied. At this time, when the swelling agents having the same concentration are used, the degree of swelling and contraction increases as the temperature rises, and the density tends to increase. On the other hand, since the polyamide-based fiber is dissolved, the strength and elongation of the conventional fiber are lowered. Therefore, it is necessary to maintain various physical properties as fibers while increasing the density, and it is desirable that the temperature is 100 ° C. or lower, preferably 90 ° C. or lower, and more preferably 80 ° C. or lower.
ポリアミド系繊維への膨潤・収縮加工後、染色後の最終段階で撥水加工を行う事が望ましい。編地に撥水加工を施す方法としてはディップニップ方式がよく、撥水剤と合わせ、架橋剤、触媒、撥水剤安定剤及び浸透剤を合わせた混合溶液を用いることが好ましい。これらの混合溶液を用いることで、加工後の編地の撥水性能や耐久性の向上が見られるためである。本発明では混合溶液を付与したのち、ドライキュアリングを行う。 It is desirable to perform water repellent treatment at the final stage after dyeing after swelling / shrinking processing on the polyamide fiber. As a method for applying the water-repellent treatment to the knitted fabric, a dip nip method is preferable, and it is preferable to use a mixed solution in which a cross-linking agent, a catalyst, a water-repellent stabilizer and a penetrant are combined with the water-repellent agent. This is because the use of these mixed solutions improves the water repellency and durability of the knitted fabric after processing. In the present invention, after applying the mixed solution, dry curing is performed.
本発明のポリアミド系高密度編地は、通気度が２０ｃｃ／ｃｍ２／ｓｅｃ以下であることが必要である。通気度は生地の表側と裏側で空気が通りやすいかを示す指標である。通気度は高いと空気が通りやすい状態であることを示し、外気を遮ることができておらずアウター素材としての使用は好ましくない。好ましくは通気度が１５ｃｃ／ｃｍ２／ｓｅｃ以下であり、さらに好ましくは１０ｃｃ／ｃｍ２／ｓｅｃ以下である。 The polyamide-based high-density knitted fabric of the present invention needs to have an air permeability of 20 cc / cm 2 / sec or less. Air permeability is an index that indicates whether air can easily pass through the front and back sides of the fabric. High air permeability indicates that air can easily pass through, and it is not possible to block the outside air, so it is not preferable to use it as an outer material. The air permeability is preferably 15 cc / cm 2 / sec or less, and more preferably 10 cc / cm 2 / sec or less.
本発明のポリアミド系高密度編地は、耐水度が２５０ｍｍＨ２Ｏ／ｃｍ２以上であることが必要である。耐水度は生地表面がどれだけの水圧に対し裏面に漏れ出さずに耐えうるかを示す指標である。耐水度が低いと外着として使用した際に、雨により内部へ浸み込みが発生する。好ましくは２５０ｍｍＨ２Ｏ／ｃｍ２以上であり、さらに好ましくは３００ｍｍＨ２Ｏ／ｃｍ２以上である。 The polyamide-based high-density knitted fabric of the present invention needs to have a water resistance of 250 mmH 2 O / cm 2 or more. Water resistance is an index showing how much water pressure the surface of the fabric can withstand without leaking to the back surface. If the water resistance is low, when it is used as an outer garment, it will seep inside due to rain. It is preferably 250 mmH 2 O / cm 2 or more, and more preferably 300 mmH 2 O / cm 2 or more.
本発明のポリアミド系高密度編地は、透湿度が６０００ｇ／ｍ２／２４ｈ以上であることが必要である。透湿度は水蒸気を外に出す性能のことである。透湿度が低いと衣服内で発生した水蒸気が外に逃げず、衣服内は蒸れ感を感じやすい状態となる。好ましくは６０００ｇ／ｍ２／２４ｈ以上である。 Polyamide dense knitted fabric of the present invention, it is necessary that the moisture permeability is 6000g / m 2 / 24h or more. Moisture permeability is the ability to release water vapor to the outside. If the moisture permeability is low, the water vapor generated inside the clothes does not escape to the outside, and the inside of the clothes tends to feel stuffy. It is preferably 6000 g / m 2 / 24h or more.
本発明のポリアミド系高密度編地は、タテ方向の伸長率が５％以上、ヨコ方向の伸長率が５％以上、一方のみではなく両方ともにあることが必要である。ストレッチ性は衣服着用時のつっぱり感を軽減させることが目的である。タテ方向、ヨコ方向ともに１０％以上であることが好ましい。さらに２５％以上であると非常にドレープ性に優れた繊維構造物が得られるため良い。 The polyamide-based high-density knitted fabric of the present invention needs to have an elongation rate of 5% or more in the vertical direction and an elongation rate of 5% or more in the horizontal direction, not only one but both. The purpose of stretchability is to reduce the feeling of tension when wearing clothes. It is preferably 10% or more in both the vertical direction and the horizontal direction. Further, when it is 25% or more, it is good because a fiber structure having very excellent drapeability can be obtained.
本発明のポリアミド系高密度編地は、剛軟度がタテ方向・ヨコ方向ともに１０〜８０ｍｍとする事が好ましい。剛軟度は生地のハリコシを示す指標であり、数値が小さいとよりハリコシ性の少ない素材となる。より好ましくはタテ方向・ヨコ方向ともに１５ｍｍ以上である。 The polyamide-based high-density knitted fabric of the present invention preferably has a rigidity of 10 to 80 mm in both the vertical and horizontal directions. Rigidity and softness is an index showing the elasticity of the fabric, and the smaller the value, the less elastic the material. More preferably, it is 15 mm or more in both the vertical direction and the horizontal direction.

The stitch density is the number of loops within a certain range and is an index showing the densification. More preferably, it is 4500 pieces / inch 2 ((2.54 cm) 2 ) or more.
本発明のポリアミド系高密度編地の優れている点は、編物でありながら防風性、耐水性、透湿性及びストレッチ性の４つを備えていることである。一般的に編物はループ構造が基本骨格としてあり、織物に比べ密な構造を得にくい素材である。本発明ではポリアミド系繊維を用いて高密度化を行っているが、ポリアミド系膨潤・収縮処理の条件が強いと高密度化した繊維構造物は得られても従来の編物が有するストレッチ性は残らない。これはポリアミド系繊維が膨潤・収縮処理により繊維自身のフィブリル化が進み、従来持っていた諸物性、特に強度や伸度が失われるためである。そこで本発明では、編組織や編条件、ポリアミド系繊維の膨潤・収縮処理に関する研究を重ね、問題解決を行った。すなわち、編地のストレッチ性を残しながら防風性、耐水性、透湿性が得られるよう、編地形成段階において構成する糸同士が３次元に重なる編地構造を構築することにした。具体的には経編地を採用し、構成する糸もフロント糸、バック糸共にポリアミド系繊維が含まれる設計とした。これにより、目標とする防風性、耐水性、透湿性を得るためのポリアミド系繊維の膨潤・収縮処理条件を緩和することが可能となり、ポリアミド系繊維の強度や伸度が維持できるようになった。 The advantage of the polyamide-based high-density knitted fabric of the present invention is that it has four properties of windproofness, water resistance, moisture permeability and stretchability, even though it is a knitted fabric. Generally, knitted fabric has a loop structure as a basic skeleton, and it is a material that is harder to obtain a dense structure than woven fabric. In the present invention, the density is increased by using polyamide fibers, but if the conditions of the polyamide-based expansion / contraction treatment are strong, even if a high-density fiber structure can be obtained, the stretchability of the conventional knitted fabric remains. Absent. This is because the polyamide fiber is swelled and shrunk to become fibrilized, and the conventional physical properties, especially strength and elongation, are lost. Therefore, in the present invention, the problems have been solved by repeating studies on the knitting structure, knitting conditions, and swelling / contracting treatment of polyamide fibers. That is, it was decided to construct a knitted fabric structure in which the yarns constituting in the knitted fabric forming stage are three-dimensionally overlapped so that windproofness, water resistance, and moisture permeability can be obtained while maintaining the stretchability of the knitted fabric. Specifically, a warp knitted fabric was adopted, and the constituent yarns were designed to contain polyamide fibers for both the front yarn and the back yarn. This makes it possible to relax the swelling / contraction treatment conditions of the polyamide fiber in order to obtain the target wind resistance, water resistance, and moisture permeability, and it has become possible to maintain the strength and elongation of the polyamide fiber. ..
本発明のポリアミド系高密度編地に関して、編成した生機の状態での目付が４０〜２００ｇ／ｍ２、最終加工後の高密度編地の状態で１００〜３６０ｇ／ｍ２であることが望ましい。これは生機での目付が低いと、防風性や、耐水性、透湿性を得るために行うポリアミド系繊維の膨潤・収縮処理条件を強くする必要があるためである。ポリアミド系繊維の膨潤・収縮条件を強くすることは、ポリアミド系繊維自身の溶解がより進み、従来の繊維の強度や伸度が低下する恐れがあるため、できるだけポリアミド系繊維の膨潤・収縮処理は条件が抑えることが望ましい。これにより生機の状態での目付は好ましくは５０〜１８０ｇ／ｍ２であり、さらに好ましくは６０〜１６０ｇ／ｍ２である。また最終加工後の高密度編地の状態で好ましくは１１５〜３４５ｇ／ｍ２であり、さらに好ましくは１３０〜３３０ｇ／ｍ２である。 Regarding the polyamide-based high-density knitted fabric of the present invention, it is desirable that the basis weight of the knitted raw machine is 40 to 200 g / m 2 and that of the high-density knitted fabric after final processing is 100 to 360 g / m 2 . This is because if the basis weight in the raw machine is low, it is necessary to strengthen the swelling / shrinking treatment conditions of the polyamide fiber to obtain wind resistance, water resistance, and moisture permeability. By strengthening the swelling / shrinking conditions of the polyamide fiber, the dissolution of the polyamide fiber itself may proceed further and the strength and elongation of the conventional fiber may decrease. Therefore, the swelling / shrinking treatment of the polyamide fiber should be performed as much as possible. It is desirable that the conditions be suppressed. As a result, the basis weight in the raw machine state is preferably 50 to 180 g / m 2 , and more preferably 60 to 160 g / m 2 . Further, it is preferably 115 to 345 g / m 2 in the state of the high-density knitted fabric after the final processing, and more preferably 130 to 330 g / m 2 .
樹脂コーティング加工やラミネート加工は、従来生地自体では得ることができない機能性や素材感を付与するために行うものである。本発明の高密度編地は樹脂コーティングやラミネート加工といった２次加工をせずとも、防風性・耐水性・透湿性・ストレッチ性を有する優れたポリアミド系高密度編地である。 The resin coating process and the laminating process are performed in order to impart functionality and texture that cannot be obtained by the conventional fabric itself. The high-density knitted fabric of the present invention is an excellent polyamide-based high-density knitted fabric having wind resistance, water resistance, moisture permeability, and stretchability without secondary processing such as resin coating or laminating.
