Description

三層積層体布帛Three-layer laminate fabric
　本発明は、防風性、防水性、透湿防水性に優れ、雨具、登山着、スポーツウェア、作業着などの各種衣料用として好適に用いられる三層の積層体布帛に関するものである。 The present invention relates to a three-layer laminate fabric that is excellent in windproof property, waterproof property, moisture permeability and waterproof property, and is suitably used for various clothes such as rain gear, mountaineering clothes, sportswear, and work clothes.
　従来から防風性や防水性、透湿防水性などが要求される衣料用途向けの布帛として、織物や編物または不織布などの生地の片面にコーティングもしくはラミネートの手段で樹脂フィルムを積層し、要求性能を満たした二層積層体からなる布帛が提案されている。 Conventionally, as a fabric for clothing applications that require windproof, waterproof, moisture-permeable and waterproof properties, a resin film is laminated on one side of fabric such as woven fabric, knitted fabric or nonwoven fabric by means of coating or laminating, and the required performance is achieved. Fabrics consisting of filled two-layer laminates have been proposed.
　しかし、織物や編物または不織布などの生地とフィルムを積層した二層積層布帛の場合、樹脂フィルムが剥離や損傷しやすく、そのため、性能が低下してしまうことや、樹脂フィルムが肌に直接接触した際にべたつき、触感が良くないという問題があった。 However, in the case of a two-layer laminated fabric obtained by laminating a fabric such as a woven fabric, a knitted fabric or a non-woven fabric with a film, the resin film is easily peeled off or damaged. There was a problem that it was sticky and the touch was not good.
　そうした問題を解決するため、織物や編物または不織布などの生地が積層されていないフィルムの面にも、織物や編物または不織布などの生地を積層させて三層の積層体とし、それにより樹脂フィルムの剥離や損傷、べたつきを抑えた布帛が提供されている。 In order to solve such a problem, a fabric such as a woven fabric, a knitted fabric or a non-woven fabric is laminated on the surface of the film, and a fabric such as a woven fabric, a knitted fabric or a non-woven fabric is laminated to form a three-layer laminate. Fabrics with reduced peeling, damage, and stickiness are provided.
　例えば、撥水性ナイロンタフタ、親水性ポリウレタン樹脂で処理された多孔質ポリテトラフルオロエチレン膜（フィルム）およびナイロントリコット編地を積層した三層積層体布帛が提案されている（特許文献１）。 For example, a three-layer laminate fabric in which a water-repellent nylon taffeta, a porous polytetrafluoroethylene film (film) treated with a hydrophilic polyurethane resin and a nylon tricot knitted fabric are laminated has been proposed (Patent Document 1).
　このような三層積層体布帛で裏面として使用する生地には、三層積層体の厚みや目付を増加させないように薄く軽いことや、あるいは肌に接触した際のべたつきを抑えることが求められる。そのために生地表面に編組織上、凹凸構造があるトリコット編地が使用されることが多い。しかし、裏面にトリコット編地を使用する場合、トリコット編地の凹凸構造に面ファスナーのフック側（クラレファスニング（株）製「ＮＥＷ　ＥＣＯ　ＭＡＧＩＣ」）やボタンなどが引っ掛かりやすく、摩耗によって劣化するという重大な問題があった。 The fabric used as the back surface of such a three-layer laminate fabric is required to be thin and light so as not to increase the thickness and basis weight of the three-layer laminate, or to suppress stickiness when contacting the skin. Therefore, a tricot knitted fabric having a concavo-convex structure on the fabric surface is often used. However, when using a tricot knitted fabric on the reverse side, the hook side of the hook-and-loop fastener (“NEW ECO MAGIC” manufactured by Kuraray Fastening Co., Ltd.) and buttons are easily caught on the uneven structure of the tricot knitted fabric, and seriously deteriorates due to wear. There was a serious problem.
　また、可撓性の防水透湿性フィルムに織物が積層されている積層体であって、該織物は平織組織からなりかつ該積層体を繊維製品に加工する際に目止め処理が施される側に積層されていて、該織物を構成する経糸および緯糸のそれぞれのカバーファクターの合計値が７００～１，３００、該経糸および緯糸の繊度が５５デシテックス以下であるという三層積層体布帛が提案されている（特許文献２（段落００５５等参照））。 Also, a laminate in which a woven fabric is laminated on a flexible waterproof and moisture-permeable film, and the woven fabric has a plain weave structure and is subjected to a sealing treatment when the laminate is processed into a textile product. A three-layer laminate fabric is proposed in which the total value of the cover factors of the warp and weft constituting the woven fabric is 700 to 1,300, and the fineness of the warp and weft is 55 dtex or less. (Patent Document 2 (see paragraph 0055, etc.)).
　この三層積層体の布帛は、例えば裏面として織物が使用されていることにより、摩耗による劣化を抑えることができる。しかし、織物は編物より風合いが硬い傾向にあるため、肌面となる裏面に使用することは好ましくない。また、織物はその重量を軽くするために密度を低下させると、外観品位が悪くなり、また風合いがさらに悪くなるという問題がある。 The fabric of this three-layer laminate can suppress deterioration due to wear, for example, by using a woven fabric as the back surface. However, since the fabric tends to be harder than the knitted fabric, it is not preferable to use the fabric on the back surface that is the skin surface. Further, when the density of the woven fabric is lowered to reduce its weight, the appearance quality is deteriorated and the texture is further deteriorated.
　また、基布の片面に透湿防水層を積層し、さらにその上に、総繊度が１６デシテックス以下の加工糸を用いてなる布帛Ａを積層した三層構造の透湿防水性布帛が提案されている（特許文献３）。 In addition, a moisture permeable waterproof fabric having a three-layer structure is proposed in which a moisture permeable waterproof layer is laminated on one side of the base fabric, and further, a fabric A using a processed yarn having a total fineness of 16 dtex or less is laminated thereon. (Patent Document 3).
　しかし、この特許文献３に提案されている透湿防水布帛は、軽量性に優れることを特徴とするもので、布帛Ａが織物の場合は風合いに問題があり、編物の場合は引っ掛かりや摩擦により劣化するという物性面の問題がある。 However, the moisture permeable and waterproof fabric proposed in Patent Document 3 is characterized by excellent lightness. When the fabric A is a woven fabric, there is a problem in the texture. There is a physical property problem of deterioration.
　以上のように、裏面の引っ掛かりや摩耗に対する物性と風合いの全てが良いという三層積層体布帛は、いまだ実現されていないのが実状である。 As described above, the actual situation is that a three-layer laminate fabric that has good physical properties and texture against catching and wear on the back surface has not been realized yet.

　本発明の目的は、上述したような点に鑑み、積層体の裏面の引っ掛かりや摩耗に対する物性と風合いの問題を解決し、衣類にしたときに着やすく、動きやすい三層積層体布帛を提供することにある。 In view of the above points, an object of the present invention is to provide a three-layer laminate fabric that is easy to wear and easy to move when it is made into clothes by solving the problems of physical properties and texture against catching and wear on the back surface of the laminate.

　以下、本発明の三層積層体布帛について、図面を用いながら詳細に説明する。 Hereinafter, the three-layer laminate fabric of the present invention will be described in detail with reference to the drawings.
　本発明の三層積層体布帛は、表面層として織物、編物、不織布の群から選ばれる一種を使用し、中層が単一の層をなしている樹脂フィルムであり、裏面層に編糸として３３デシテックス以下の捲縮を有さない合成繊維マルチフィラメント糸条のストレートヤーンが使用されてかつ６．４５ｃｍ2当たりの編目数が５，５００～１２，０００個である天竺組織のシングル丸編地のみを使用し、該シングル編地のシンカーループ面を前記中層との接着面として、前記表面層、前記中層および該裏面層が積層されてなり、該裏面層の平均摩擦係数が０．０５～０．１９であることを特徴とする。 The three-layer laminate fabric of the present invention is a resin film in which one kind selected from the group of woven fabric, knitted fabric and non-woven fabric is used as the surface layer, the middle layer is a single layer, and the back layer is 33 as knitting yarn. Only single round knitted fabrics with a tengu structure with straight yarns of synthetic fiber multifilament yarns having no crimps below decitex and having 5,500 to 12,000 stitches per 6.45 cm 2 The surface layer, the middle layer and the back layer are laminated with the sinker loop surface of the single knitted fabric as the adhesive surface with the middle layer, and the average friction coefficient of the back layer is 0.05-0. .19.
　シングル丸編地は、編目で生地が構成され、図１に示したように、構成糸Ａの連結がルーズに動くことができるため柔らかい風合いとなる。さらにシングル丸編地は、表面（ニードルループ面）が図１に示すように編目の隙間はあるものの平滑な構造であり、裏面（シンカーループ面）が図２に示すように編目の連結部が凸部となる凹凸構造を呈している。裏面層は、後述するように編地面積６．４５ｃｍ2当たりの編目数が５，５００～１２，０００個である天竺組織のシングル丸編地のみで形成されている。 The single circular knitted fabric has a soft texture because the fabric is composed of stitches and the connection of the constituent yarn A can move loosely as shown in FIG. Further, the single circular knitted fabric has a smooth structure with the surface (needle loop surface) having a gap between the stitches as shown in FIG. 1, and the back surface (sinker loop surface) has a stitch connecting portion as shown in FIG. The concavo-convex structure which becomes a convex part is exhibited. As will be described later, the back surface layer is formed only of a single circular knitted fabric with a tengu structure having a number of stitches per knitted fabric area of 6.45 cm 2 of 5,500 to 12,000.
　本発明の三層積層体布帛では、シングル編地の裏面である凹凸構造のある面（シンカーループ面）を接着面として中層の樹脂フィルムと積層する。そのため、積層したときに凸部のみ接着されるため、丸編地の柔らかい風合いを残すことができる。 In the three-layer laminate fabric of the present invention, the surface having a concavo-convex structure (sinker loop surface), which is the back surface of a single knitted fabric, is laminated with an intermediate resin film. Therefore, since only the convex portions are bonded when laminated, the soft texture of the circular knitted fabric can be left.
　なお、従来からの一般的な丸編地では面ファスナーなどに対する物性が悪い、つまり、面ファスナーに引っかかりやすいものであった。その点を改善するため、本発明において積層体布帛の裏面層に使用する生地は、特にシングル丸編地であって、編地面積６．４５ｃｍ2 当たりの編目数が５，５００～１２，０００個のものを使用することが重要である。６．４５ｃｍ2 あたりの編目数とは、２．５４ｃｍ当たりのウエル数と２．５４ｃｍ当たりのコース数を掛け算した値であり、この編目数が多ければ編目の間隔が狭く詰まった生地になり、少なければ編目の間隔が広く粗い生地となる。 In addition, the conventional general circular knitted fabric has poor physical properties with respect to the hook-and-loop fastener, that is, it is easily caught by the hook-and-loop fastener. In order to improve this point, the fabric used for the back layer of the laminate fabric in the present invention is particularly a single circular knitted fabric, and the number of stitches per knitted fabric area of 6.45 cm 2 is 5,500 to 12,000. It is important to use one piece. The number of stitches per 6.45 cm 2 is a value obtained by multiplying the number of wells per 2.54 cm and the number of courses per 2.54 cm. If there are few, it will become a coarse cloth with wide stitch intervals.
　すなわち、シングル丸編地は平滑な表面を有しているといっても、編目数が５，５００個未満になると編目の間隔が広くなりすぎるため、面ファスナーなどに引っ掛かりやすくなり物性が悪くなってしまう。編目数を多くすれば編目の間隔が狭くなるため引っかかりなどに対する物性は良くなる（引っかかりにくくなる）ものの、１２，０００個よりも多いと目付が重く肉厚になり過ぎ、積層体布帛全体に与える影響が大きくなってしまう。 That is, even though a single circular knitted fabric has a smooth surface, if the number of stitches is less than 5,500, the interval between the stitches becomes too wide, so that it is easily caught on a hook-and-loop fastener and the physical properties deteriorate. End up. If the number of stitches is increased, the interval between stitches becomes narrow and the physical properties against catching and the like are improved (it becomes difficult to catch). However, if the number is greater than 12,000, the basis weight is too heavy and too thick, giving the entire laminate fabric The effect will be greater.
　編地面積６．４５ｃｍ2 当たりの編目数は、６，０００～１１，５００個の範囲内であることが好ましく、さらに、６，５００～１１，０００個の範囲内であることがより好ましい。 The number of stitches per knitted fabric area of 6.45 cm 2 is preferably in the range of 6,000 to 11,500, and more preferably in the range of 6,500 to 11,000.
　また、２．５４ｃｍ当たりのウエル数は７２個よりも多いことが好ましい。ウエル数とコース数ともに個数が多い方が平滑になり物性に良い影響を与えるが、ウエル数の方が特に影響を及ぼす。ウエル数が少なくなるということは幅方向に引っ張られ編目が広がることになり、図３に示すように隙間Ｄが広がり、表面にも凹凸構造がある生地となってしまうので好ましくない。すなわち、表面にも凹凸構造ができることにより、面ファスナーなどに対する物性が悪くなり、滑らかさも失われてしまうので好ましくない。 Also, the number of wells per 2.54 cm is preferably more than 72. A larger number of both the number of wells and the number of courses results in smoother and better influences on physical properties, but the number of wells has a particular influence. Reducing the number of wells is not preferable because the stitches are stretched in the width direction and the stitches are widened, the gap D is widened as shown in FIG. 3, and the surface has a concavo-convex structure. That is, it is not preferable that the surface has a concavo-convex structure, which deteriorates physical properties with respect to a hook-and-loop fastener and loses smoothness.
　シングル丸編地を構成する編糸は、３３デシテックス以下の合成繊維マルチフィラメント糸であることが重要である。３３デシテックスを越えて太くなると目付が重く肉厚になりすぎ、積層体布帛全体に与える影響が大きくなってしまう。編糸の繊度は２３デシテックス以下４デシテックス以上であることが好ましく、１７デシテックス以下７デシテックス以上であることがより好ましい。 It is important that the knitting yarn constituting the single circular knitted fabric is a synthetic fiber multifilament yarn of 33 dtex or less. If the thickness exceeds 33 decitex, the basis weight is too heavy and too thick, and the effect on the entire laminate fabric is increased. The fineness of the knitting yarn is preferably 23 dtex or less and 4 dtex or more, and more preferably 17 dtex or less and 7 dtex or more.
　該合成繊維マルチフィラメント糸の単繊維繊度は、０．４～１０デシテックスの範囲であることが好ましく、１．２～８デシテックスの範囲であることがより好ましい。単繊維繊度が１０デシテックス以下であることにより裏面の風合いがより柔らかい積層体布帛を得ることができる。単繊維繊度が０．４デシテックス未満になると糸が細すぎるため、引っ掛かりや摩耗に対する物性の悪いものとなってしまう。 The single fiber fineness of the synthetic multifilament yarn is preferably in the range of 0.4 to 10 dtex, and more preferably in the range of 1.2 to 8 dtex. When the single fiber fineness is 10 dtex or less, it is possible to obtain a laminate fabric having a softer back surface texture. If the single fiber fineness is less than 0.4 decitex, the yarn is too thin, resulting in poor physical properties against catching and wear.
　合成繊維は、特に限定されるものではないが、強度、耐久性、加工性、コストの観点からポリエステル繊維またはポリアミド繊維であることが好ましい。 The synthetic fiber is not particularly limited, but is preferably a polyester fiber or a polyamide fiber from the viewpoint of strength, durability, processability, and cost.
　該合成繊維マルチフィラメント糸は、捲縮加工や嵩高加工などの高次加工がされていないストレートヤーンである生糸（なまいと）を使用する。特に、裏地を面ファスナーなどが引っかかりにくく、かつ滑らかな表面にするためには単繊維がバラけにくく集束性の良い糸を使用することが好ましい。中でもストレートヤーンである生糸を使用することが重要なものである。生糸を使用することにより、引っかかりや摩耗に対する物性や衣料にしたときの着用のしやすさ、動きやすさをさらに向上させることができる。なお、ストレートヤーンである生糸とは、製糸段階で集束性をもたせるために圧空の噴射で付与される軽い交絡程度の交絡を持つものをも含む概念である。 The synthetic fiber multifilament yarn is a raw yarn that is a straight yarn that has not been subjected to higher-order processing such as crimping or bulking. In particular, in order to make the lining difficult to catch a hook-and-loop fastener or the like and to have a smooth surface, it is preferable to use a yarn that is easy to bundle and has good converging properties. Among them, it is important to use raw yarn which is a straight yarn. By using raw silk, it is possible to further improve the physical properties against catching and wear, the ease of wearing and the ease of movement when used as clothing. In addition, the raw yarn which is a straight yarn is a concept including the thing which has the entanglement of the light entanglement grade given by the injection of a compressed air in order to give convergence property at the stage of a yarn production.
　シングル丸編地は、編機の選択・編み条件の設定を行い製編し、染色加工でウエル数とコース数の設定に合う条件で染色することにより、目的の編目数に仕上げることができる。 Single circular knitted fabric can be finished to the desired number of stitches by selecting the knitting machine, setting the knitting conditions, knitting, and dyeing under conditions that match the settings of the number of wells and the number of courses.
　編機は、４６ゲージ以上のシングル丸編機を用いて編成することが好ましく、６０ゲージ以上のシングル丸編機を用いることがより好ましい。４６ゲージ未満の編機を使用した場合、目的のウエル数とコース数を得ることができないか、もしくは上述した図３に示した編目の間隙Ｄが広がってしまうことが起きるため引っ掛かりや摩耗に対する物性の良いシングル丸編地を得ることができなくなり好ましくない。編組織は、目付、厚み、表面摩擦係数の低さ、コストを考慮すると天竺組織であることが重要である。 The knitting machine is preferably knitted using a single circular knitting machine of 46 gauge or more, and more preferably a single circular knitting machine of 60 gauge or more. When a knitting machine of less than 46 gauge is used, the desired number of wells and the number of courses cannot be obtained, or the stitch gap D shown in FIG. It is not preferable because a good single circular knitted fabric cannot be obtained. In consideration of the basis weight, thickness, low surface friction coefficient, and cost, it is important that the knitted structure is a tense structure.
　染色加工は、従来から知られている染色方法で加工することができる。 The dyeing process can be performed by a conventionally known dyeing method.
　本発明の三層積層体布帛の表面層に使用する生地は、織物、編物、不織布のいずれか一種である。組織は特に限定されないが、織物としては、平織、綾織、朱子織、ななこ織、急斜文織、よこ二重織、たて二重織などを使用することができ、編物としては、緯編地である平編（天竺）、鹿の子編、リブ編、両面編（スムース）、パール編、ポンチローマ編、ミラノリブ編、ブリスター編など、縦編地であるシングルデンビ編、シングルコード編、シングルアトラス編、ハーフトリコット編、ダブルデンビ編、サテン編などを使用することができ、不織布としては、短繊維不織布、長繊維不織布、乾式不織布、湿式不織布などを使用することができる。 The fabric used for the surface layer of the three-layer laminate fabric of the present invention is any one of a woven fabric, a knitted fabric, and a nonwoven fabric. Although the structure is not particularly limited, plain weaving, twill weaving, satin weaving, Nanako weaving, steep oblique weaving, weft double weaving, warp double weaving, etc. can be used, and weaving as weaving Flat knitting (Tengu), Kanoko knitting, rib knitting, double-sided knitting (smooth), pearl knitting, punch Rome knitting, Milan rib knitting, blister knitting, etc. Atlas knitting, half tricot knitting, double denvi knitting, satin knitting and the like can be used. As the nonwoven fabric, short fiber nonwoven fabric, long fiber nonwoven fabric, dry nonwoven fabric, wet nonwoven fabric and the like can be used.
　また、前記表面層に使用する生地の構成素材は、綿、麻などの天然繊維、ポリエステル繊維、ポリアミド繊維などの合成繊維などから、その積層体布帛が使用される用途に応じて選定することができる。例えば、本発明の三層積層体布帛を強度、耐久性、軽量性などが重視される登山着に使用する場合は、ポリエステル繊維、ポリアミド繊維などから構成された織物を使用することが好ましく、ストレッチ性、軽量性などが重視されるスポーツウェアに使用する場合は、ポリエステル繊維、ポリアミド繊維などから構成された編物を使用することが好ましい。また、該生地に対しては、必要に応じて従来から知られている撥水処理加工、制電処理加工などを施してもよい。 In addition, the constituent material of the fabric used for the surface layer may be selected from natural fibers such as cotton and hemp, synthetic fibers such as polyester fibers and polyamide fibers according to the use for which the laminate fabric is used. it can. For example, when the three-layer laminate fabric of the present invention is used for mountaineering where importance is placed on strength, durability, lightness, etc., it is preferable to use a woven fabric composed of polyester fiber, polyamide fiber, etc. When it is used for sportswear in which importance is placed on performance, lightness, etc., it is preferable to use a knitted fabric composed of polyester fiber, polyamide fiber or the like. In addition, the fabric may be subjected to conventionally known water repellent treatment, antistatic treatment, or the like as necessary.
　本発明の三層積層体布帛の中層は、単一の層をなしている樹脂フィルムであり、該樹脂フィルムは、従来から知られている各種の樹脂フィルムを使用することができる。ここで、「単一の層をなしている樹脂フィルム」とは、一枚のフィルムが、その表面にコーティング加工を施されているもの、あるいは、表面に改質加工をされているものなどを含む。 The middle layer of the three-layer laminate fabric of the present invention is a resin film forming a single layer, and various resin films known in the art can be used as the resin film. Here, the “resin film forming a single layer” means that a single film is coated on the surface or modified on the surface. Including.
　樹脂フィルムの材料としては、例えば、ポリウレタン系樹脂、アクリル系樹脂、ポリ塩化ビニル系樹脂、ポリエステル系樹脂、ポリエチレン系樹脂、ポリプロピレン系樹脂、含フッ素系樹脂、ポリアミド系樹脂、ポリイミド系樹脂などがあり、使用する用途に応じて適宜選択すればよい。厚さは、３～１００μｍであることが好ましく、より好ましくは５～５０μｍである。目付は、３～６０ｇ／ｍ2 の範囲内であることが好ましく、より好ましくは３～５０ｇ／ｍ2 の範囲内である。 Examples of resin film materials include polyurethane resins, acrylic resins, polyvinyl chloride resins, polyester resins, polyethylene resins, polypropylene resins, fluorine-containing resins, polyamide resins, and polyimide resins. And may be appropriately selected according to the intended use. The thickness is preferably 3 to 100 μm, more preferably 5 to 50 μm. The basis weight is preferably in the range of 3 to 60 g / m 2 , more preferably in the range of 3 to 50 g / m 2 .
　例えば、透湿防水性の衣料に用いる場合は、ポリウレタン系樹脂、ポリエステル樹脂、含フッ素系樹脂などからなる透湿防水性フィルムを使用することが好ましい。また、透湿防水性フィルムには湿式製法により製造される多孔質樹脂薄膜と、乾式製法により製造される親水性無孔質樹脂薄膜とに分けられ、それぞれ以下のような特徴に基づいて使い分けるとよい。 For example, when used for moisture-permeable and waterproof clothing, it is preferable to use a moisture-permeable and waterproof film made of polyurethane resin, polyester resin, fluorine-containing resin or the like. In addition, the moisture-permeable and waterproof film can be divided into a porous resin thin film produced by a wet production method and a hydrophilic nonporous resin thin film produced by a dry production method. Good.
　多孔質樹脂薄膜は、その内部に超微細で均一に分散する多数の気孔が、互いに連通した状態で形成されている連続気泡体であって、かつ、その孔幅が略０．３～３μｍのものであることが好ましい。水蒸気の粒径は略０．４ｎｍ程度であり、雨や水の粒径は略０．１～３ｍｍ程度の範囲であるため、気孔の孔幅より粒径の小さい水蒸気は通過し、気孔の孔幅より粒径の大きい雨や水の浸透は阻止できることにより優れた透湿防水性を発揮する。 The porous resin thin film is an open cell body in which a large number of pores that are ultrafine and uniformly dispersed therein are formed in communication with each other, and the pore width is approximately 0.3 to 3 μm. It is preferable. Since the water vapor has a particle size of about 0.4 nm and the particle size of rain and water is in the range of about 0.1 to 3 mm, water vapor having a particle size smaller than the pore width passes through the pores. It has excellent moisture permeability and waterproofness by preventing the penetration of rain and water having a particle size larger than the width.
　また、親水性無孔質樹脂薄膜は、上記した多孔質樹脂薄膜とは異なり連続気泡状の多数の気孔を有しておらず、内部に親水性を有した親水基を持つことにより透湿機能が確保されている。親水性無孔質樹脂薄膜の片面側の水蒸気濃度が上昇すると、薄膜内部の親水基により薄膜内へ水蒸気が取りこまれ、さらに、薄膜内の水蒸気は水蒸気濃度の低い他面側へ移行する。このように親水性無孔質樹脂薄膜は、自己の親水基により水蒸気を通過させることで優れた透湿防水性を発揮する。 In addition, unlike the porous resin thin film described above, the hydrophilic non-porous resin thin film does not have a large number of open-celled pores, and has a hydrophilic group having hydrophilicity inside, thereby providing a moisture-permeable function. Is secured. When the water vapor concentration on one side of the hydrophilic nonporous resin thin film increases, the water vapor is taken into the thin film by the hydrophilic group inside the thin film, and further, the water vapor in the thin film moves to the other surface side where the water vapor concentration is low. Thus, the hydrophilic nonporous resin thin film exhibits excellent moisture permeability and waterproofness by allowing water vapor to pass through its own hydrophilic group.
　本発明において、樹脂フィルムと、織物、編物、不織布から選ばれるいずれか一種の表地およびシングル丸編地である裏地とを積層する手法は、表地または裏地の布帛に直接コーティングする方法や、皮膜（フィルム）を作製し布帛に接着剤などで接着するラミネート法など、従来から知られている製造法を用いて積層することができる。 In the present invention, a method of laminating a resin film and any one kind of outer fabric selected from woven fabric, knitted fabric, and nonwoven fabric and a backing that is a single circular knitted fabric includes a method of directly coating the outer fabric or the fabric of the lining, Film) and can be laminated using a conventionally known manufacturing method such as a laminating method in which the film is adhered to the fabric with an adhesive or the like.
　直接コーティングする方法とは、目的に応じた樹脂を布帛の一面に均一な薄膜状に直接塗工し皮膜化（フィルム化）することであり、水中を通過させ皮膜化する湿式と乾燥することによって皮膜化する乾式がある。樹脂を塗工する方法としては、一般的には、ナイフオーバーロールコーティング、ダイレクトロールコーティング、リバースロールコーティング、グラビアコーティングなどがあり、そのコーティング処方を利用し所望の膜厚となるように塗工すればよい。 The direct coating method is to directly apply a resin according to the purpose in a uniform thin film form on one side of the fabric to form a film (film), by passing it through water to form a film and to dry the film. There is a dry type that turns into a film. Generally, there are knife over roll coating, direct roll coating, reverse roll coating, gravure coating, etc., as the method of coating resin. That's fine.
　ラミネート法とは、目的に応じた樹脂を予め皮膜化し、その上に接着剤を塗工して布帛を積層することである。接着剤を塗工する方法としては、一般的にはナイフオーバーロールコーティング、ダイレクトロールコーティング、リバースロールコーティング、グラビアコーティングなどがあり、そのコーティング処方を利用し所望の膜厚、被覆率となるように塗工すればよい。 The laminating method is to form a resin according to the purpose in advance and apply an adhesive thereon to laminate the fabric. In general, there are knife over roll coating, direct roll coating, reverse roll coating, gravure coating, etc., as the method of applying the adhesive, so that the coating formulation can be used to achieve the desired film thickness and coverage. Just apply.
　接着剤は、熱可塑性樹脂接着剤の他、熱や光などとの反応をして硬化する硬化性樹脂接着剤など、従来から知られているものを使用することができる。例えば、ポリエステル樹脂、ポリアミド樹脂、ポリウレタン樹脂、シリコーン樹脂、アクリル樹脂、ポリ塩化ビニル樹脂、あるいはポリオレフィン樹脂などがある。特に、本発明の三層積層体布帛を透湿防水性の衣類に用いる場合は、透湿性の高いものが好ましい。 As the adhesive, conventionally known ones such as a curable resin adhesive that is cured by a reaction with heat or light in addition to a thermoplastic resin adhesive can be used. For example, there are a polyester resin, a polyamide resin, a polyurethane resin, a silicone resin, an acrylic resin, a polyvinyl chloride resin, and a polyolefin resin. In particular, when the three-layer laminate fabric of the present invention is used for moisture-permeable and waterproof clothing, one having high moisture permeability is preferable.
　接着剤による被覆率は、特に限定されないが、高い方が剥離強度は高くなる。例えば、本発明の三層積層体布帛を透湿防水性の衣類に用いる場合、高透湿性の接着剤であれば１００％被覆の全面接着でも問題はないが、透湿性と耐水性の両立を考えると一般的には４０～８０％の被覆率とすることが好ましい。被覆率が１００％の全面接着としたい場合は、ナイフコーターなどを用い、被覆率が４０～８０％とコントロールする場合はグラビアコーターなどを用いて実施することができる。グラビアコーターは、表面にドット状の凹部を彫刻したロールを用い、その凹部に接着剤を入れ樹脂フィルムに転移させて加工する方法であり、凹部の面積および深さ、凹部間の間隔を調整することにより被覆率を自由に設定することができる。 The coverage with the adhesive is not particularly limited, but the higher the peel strength is. For example, when the three-layer laminate fabric of the present invention is used for moisture-permeable and waterproof clothing, there is no problem even with 100% covering of the entire surface if it is a highly moisture-permeable adhesive, but it is compatible with moisture permeability and water resistance. In general, the coverage is preferably 40 to 80%. A knife coater or the like can be used to achieve full coverage with a coverage of 100%, and a gravure coater or the like can be used to control the coverage to 40 to 80%. The gravure coater is a method of processing by using a roll engraved with dot-shaped recesses on the surface and transferring the adhesive to the recesses and transferring it to a resin film, and adjusting the area and depth of the recesses and the spacing between the recesses. Thus, the coverage can be freely set.
　上記の方法を用いて、表面層に織物、編物、不織布の群の中から選ばれる一種を採用し、中層に樹脂フィルムを採用し、裏面層に３３デシテックス以下の合成繊維マルチフィラメント糸条からなり６．４５ｃｍ2 当たりの編目数が５，５００～１２，０００個のシングル丸編地を採用して、図４のように三層に積層して本発明の三層積層体布帛を得ることができる。 Using the above method, the surface layer employs a kind selected from the group of woven fabric, knitted fabric, and nonwoven fabric, the middle layer employs a resin film, and the back surface layer comprises synthetic fiber multifilament yarns of 33 dtex or less. 6. A single circular knitted fabric having 5,500 to 12,000 stitches per 45 cm 2 is adopted and laminated into three layers as shown in FIG. 4 to obtain the three-layer laminate fabric of the present invention. it can.
　さらに本発明の三層積層体布帛は、その裏面層の平均摩擦係数μが０．０５～０．１９の範囲内にあることが重要であり、特に平均摩擦係数μが０．０７～０．１８の範囲であることがより好ましい。平均摩擦係数μとは、摩擦の大きさを示し、数値が小さいほど摩擦は少なく滑りの良い生地であるということである。平均摩擦係数μを０．１９以下にすることにより、滑りが良くなり、着用しやすく動きやすくするという裏地の特性をより発揮することができ、また、滑りが良いことにより面ファスナーやボタンなどに擦れても、傷つきにくいものとなる。一方、０．０５未満になると滑りが良くなりすぎるため、縫製時にパーツがずれやすくなるなど加工性が低下してしまうので好ましくない。 Furthermore, it is important that the average friction coefficient μ of the back layer of the three-layer laminate fabric of the present invention is in the range of 0.05 to 0.19, and particularly the average friction coefficient μ is 0.07 to 0.00. A range of 18 is more preferable. The average friction coefficient μ indicates the magnitude of friction, and the smaller the value, the less the friction and the better the slip. By making the average friction coefficient μ 0.19 or less, slipping is improved, and it is possible to demonstrate the characteristics of the lining which makes it easy to wear and easy to move. Even if rubbed, it becomes hard to be damaged. On the other hand, if it is less than 0.05, the slipping is too good, so that the workability is lowered such that parts are easily displaced during sewing, which is not preferable.
　ここで、平均動摩擦係数μとはＫＥＳ（Kawabata Evaluation System）風合いシステムの表面試験機により縦方向と横方向の動摩擦係数を測定し、平均した値である。衣類にした場合、一方方向に動くわけではないため、縦方向と横方向の動摩擦係数を平均した値で評価をしている。 Here, the average dynamic friction coefficient μ is a value obtained by measuring the longitudinal and lateral dynamic friction coefficients with a surface tester of a KES (Kawabata Evaluation System) texture system and averaging them. When clothing is used, it does not move in one direction, so the evaluation is based on the average value of the dynamic friction coefficients in the vertical and horizontal directions.
　本発明の三層積層体布帛は、その裏面層の平均表面粗さが７μｍ以下であることが好ましく、５μｍ以下であることがより好ましい。平均表面粗さとは、生地表面の凹凸構造の差を示し、数値が大きいほど凹凸の差があることになる。７μｍを越えると表面の凹凸構造の差がありすぎるため、面ファスナーなどに引っ掛かりやすく物性が悪くなってしまう。また、手で触れたときざらざらしていると感じるようになってしまう。平均表面粗さの下限は０．８μｍ程度までである。 The average surface roughness of the back layer of the three-layer laminate fabric of the present invention is preferably 7 μm or less, and more preferably 5 μm or less. The average surface roughness indicates a difference in the uneven structure on the surface of the fabric, and a larger numerical value indicates a difference in unevenness. If it exceeds 7 μm, there is too much difference in the concavo-convex structure on the surface, so that it is easily caught on a hook-and-loop fastener and the physical properties are deteriorated. Also, when you touch it with your hand, you will feel it is rough. The lower limit of the average surface roughness is about 0.8 μm.
　ここで、平均表面粗さとはＫＥＳ風合いシステムの表面試験機により縦方向と横方向の表面粗さを測定し、平均した値である。衣類にした場合、一方方向に動くわけではないため、縦方向と横方向の表面粗さを平均した値を求めて評価をしている。 Here, the average surface roughness is a value obtained by measuring the surface roughness in the vertical direction and the horizontal direction with a surface testing machine of a KES texture system and averaging the measured values. In the case of clothing, it does not move in one direction, so evaluation is performed by obtaining an average value of surface roughness in the vertical and horizontal directions.
　本発明の三層積層体布帛に使用するシングル丸編地は、カバーファクター（ＣＦ）が４００～９００の範囲であることが好ましく、４５０～８５０の範囲であることがより好ましい。カバーファクターは下記の式にて算出することができる。
　ＣＦ　＝　｛　√Ｔ　×　Ｗ　｝＋　｛　√Ｔ　×　Ｃ　｝
　ＣＦ：　カバーファクター
　Ｔ　：　構成糸の繊度（デシテックス）
　Ｗ　：　生地のヨコの長さ２．５４ｃｍあたりのウエル数
　Ｃ　：　生地のタテの長さ２．５４ｃｍあたりのコース数
　カバーファクターが４００未満になると編地密度が低くなり過ぎるため、引っ掛かりや摩耗に対する物性や滑りが悪くなり、９００を越えると編地密度が高くなり過ぎるため、目付が重く積層体布帛全体に与える影響が大きくなってしまう。 The single circular knitted fabric used for the three-layer laminate fabric of the present invention preferably has a cover factor (CF) in the range of 400 to 900, and more preferably in the range of 450 to 850. The cover factor can be calculated by the following formula.
CF = {√T × W} + {√T × C}
CF: Cover factor T: Fineness of the component yarn (decitex)
W: Number of wells per 2.54 cm length of fabric width C: Number of courses per 2.54 cm length of fabric length When the cover factor is less than 400, the knitted fabric density becomes too low. If the physical properties and slippage are deteriorated and the knitted fabric density exceeds 900, the knitted fabric density becomes too high, so that the weight per unit area is heavy and the influence on the entire laminate fabric is increased.
　本発明の三層積層体布帛は、全体の目付が５０～１５０ｇ／ｍ2 の範囲であることが好ましく、６０～１４０ｇ／ｍ2 の範囲であることがより好ましい。１５０ｇ／ｍ2 を越えると衣類にしたときにかなり重くなり着心地が悪くなるので、用途によって好ましくない場合が多い。５０ｇ／ｍ2 未満になると、軽すぎるため、引裂強度などが弱くなり衣類にしたときに傷みやすいものになってしまうことから、用途面で好ましくない場合がある。 The total weight of the three-layer laminate fabric of the present invention is preferably in the range of 50 to 150 g / m 2 , more preferably in the range of 60 to 140 g / m 2 . If it exceeds 150 g / m 2 , it will be quite heavy when worn and uncomfortable, so it is often undesirable depending on the application. If it is less than 50 g / m 2 , it is too light, so that the tear strength and the like are weakened, and it becomes easy to be damaged when it is made into clothing, which may be undesirable in terms of use.
　本発明の三層積層体布帛は、厚さが０．０８～０．６ｍｍの範囲であることが好ましく、０．１～０．５ｍｍの範囲であることがより好ましい。０．６ｍｍを越えると厚すぎるため、衣類にして着用したときに動きにくいものとなってしまうので用途面で制約が生ずる。０．０８ｍｍ未満になると薄すぎるため、引裂強度などの物理特性が低下し衣類にしたときに傷みやすく好ましくない。 The thickness of the three-layer laminate fabric of the present invention is preferably in the range of 0.08 to 0.6 mm, and more preferably in the range of 0.1 to 0.5 mm. If it exceeds 0.6 mm, it is too thick, and it becomes difficult to move when worn as a garment. If it is less than 0.08 mm, it is too thin, and physical properties such as tear strength are lowered, and it is not preferable because it is easily damaged when it is made into clothes.
　また、本発明の三層積層体布帛は、裏面層の摩擦係数の平均偏差が０．０２７以下であることが好ましく、０．０２３以下であることがより好ましい。摩擦係数の平均偏差とは、摩擦係数の変動を示し数値が大きくなるほど、ざらつきを感じるようになる。摩擦係数の平均偏差が０．０２７を越えるとざらつきが大きくなり過ぎるため、手で触れたり、着用したときに不快に感じるようになってしまう場合がある。 In the three-layer laminate fabric of the present invention, the average deviation of the friction coefficient of the back layer is preferably 0.027 or less, more preferably 0.023 or less. The average deviation of the friction coefficient indicates the fluctuation of the friction coefficient, and the larger the value, the more the roughness becomes felt. When the average deviation of the coefficient of friction exceeds 0.027, the roughness becomes too large, which may make the user feel uncomfortable when touched or worn.
　ここで、摩擦係数の平均偏差とはＫＥＳ風合いシステムの表面試験機により縦方向と横方向の摩擦係数平均偏差を測定し、平均した値である。衣類にした場合、一方方向に動くわけではないので、縦方向と横方向の摩擦係数の平均偏差を平均した値で評価をする。 Here, the average deviation of the friction coefficient is a value obtained by measuring the average deviation of the friction coefficient in the longitudinal direction and the transverse direction with a surface testing machine of the KES texture system. When clothing is used, it does not move in one direction, so evaluation is made by averaging the average deviations of the friction coefficients in the vertical and horizontal directions.
　本発明の三層積層体布帛は、平均曲げ剛性が０．８～１８ｇｆ・ｃｍ2／ｃｍの範囲であることが好ましく、０．１～１５ｇｆ・ｃｍ2／ｃｍの範囲であることがより好ましい。平均曲げ剛性とは、生地の曲げ硬さを示し数値が小さいほど柔らかい生地となる。平均曲げ剛性が１８ｇｆ・ｃｍ2／ｃｍを越えると生地が硬くなりすぎるため、衣類にして着用したときに動きにくいものとなってしまう。０．８ｇｆ・ｃｍ2／ｃｍ未満になると生地が柔らかくなりすぎるため、引裂きや破裂などの強度が低下し、衣類に適さないものとなってしまう。 The three-layer laminate fabric of the present invention preferably has an average bending stiffness in the range of 0.8 to 18 gf · cm 2 / cm, and more preferably in the range of 0.1 to 15 gf · cm 2 / cm. . The average bending stiffness indicates the bending hardness of the fabric, and the smaller the value, the softer the fabric. If the average bending stiffness exceeds 18 gf · cm 2 / cm, the fabric becomes too hard, and thus it becomes difficult to move when worn as clothing. If it is less than 0.8 gf · cm 2 / cm, the fabric becomes too soft, so that the strength such as tearing or rupture is lowered, and it becomes unsuitable for clothing.
　ここで、平均曲げ剛性とはＫＥＳ風合いシステムの純曲げ試験機により縦方向と横方向の曲げ剛性を測定し、平均した値である。衣類にした場合、一方方向に曲げる力が働くわけではないため、縦方向と横方向の曲げ剛性を平均した値を評価している。 Here, the average bending stiffness is an average value obtained by measuring the bending stiffness in the vertical direction and the horizontal direction with a pure bending tester of KES texture system. In the case of clothing, since the bending force in one direction does not work, the average value of the bending rigidity in the vertical direction and the horizontal direction is evaluated.

In addition, each physical property in an Example is measured with the following method.
(1) Number of stitches per 6.45 cm 2 The number of stitches was calculated by multiplying the number of wells per 2.54 cm of the knitted fabric and the number of courses. In the measurement, the number of wells per 2.54 cm and the number of courses of the flatly placed dough were counted, and each of five locations was measured, and the average value was obtained by rounding off the decimal point.

A 20 × 20 cm test piece is applied with a tension of 20 gf / cm in an environment of 20 ° C. × 65% RH, and a sample of 50 gf is applied to a contact member in which a 0.5 mmφ piano wire is wound on 10 × 5 × 5 mm. And is moved horizontally at a constant speed of 0.1 cm / second, and the coefficient of friction (MIU) is measured.
