Description
本発明は、防透性と通気性とを同時に有する２層構造織物及び該２層構造織物を用いて縫製してなる繊維製品に関するものである。 The present invention relates to a two-layer structure woven fabric having permeation resistance and air permeability at the same time, and a textile manufactured by sewing using the two-layer structure woven fabric.
ユニフォーム、白衣、シャツなどの用途では、着用時に肌が透けてみえない防透性と通気性とが同時に求められている。しかしながら、防透性と通気性とは、通常相反する特性である。例えば、通気性を得るために布帛の織編密度を低くすると、隣りあう糸条間に空隙ができ、この空隙から肌が透けて十分な防透性が得られない。逆に、防透性を得るために布帛の織編組織を高くすると、空気の通りが阻害され通気性が低下してしまう。 In applications such as uniforms, lab coats, shirts, and the like, there is a demand for permeability and breathability that prevents skin from being seen through when worn. However, permeation and breathability are usually contradictory characteristics. For example, if the weaving and knitting density of the fabric is lowered in order to obtain air permeability, a gap is formed between adjacent yarns, and the skin passes through the gap, so that sufficient permeation resistance cannot be obtained. On the other hand, if the weaving and knitting structure of the fabric is made high in order to obtain the permeation resistance, the passage of air is inhibited and the air permeability is lowered.
このような相反する特性を満足させるために、例えば、特許文献１では、繊維中に艶消し剤を十分に練り込み、該繊維を用いて繊維構造体を構成することが提案されている。かかる方法によれば、繊維自身を透過する光線が艶消し剤によって散乱するため、ある程度防透性は向上する。しかるに、糸条間からの光の通過は避けられないため、やはり織編密度をあげざるを得ず通気性が低下してしまうという問題があった。 In order to satisfy such conflicting characteristics, for example, Patent Document 1 proposes that a matting agent is sufficiently kneaded into fibers and a fiber structure is formed using the fibers. According to such a method, since the light beam that passes through the fiber itself is scattered by the matting agent, the permeability is improved to some extent. However, since the passage of light between the yarns is unavoidable, there is a problem that the air permeability is lowered due to the necessity of increasing the woven / knitting density.
他方、特許文献２では、２層構造を有する織物が提案されているが、該２層構造織物は、織物に吸水性重合体を付着させることにより制電性や吸汗性を向上させることを目的とするものであり、防透性及び通気性の点で満足とはいえなかった。
本発明は、上記の背景に鑑みなされたものであり、その目的は、防透性と通気性とを同時に有する２層構造織物、及び該２層構造織物を用いて縫製してなる繊維製品を提供することにある。 The present invention has been made in view of the above-described background, and an object of the present invention is to provide a two-layer structure fabric having both permeation resistance and breathability, and a textile product obtained by sewing using the two-layer structure fabric. It is to provide.
本発明者らは、上記目的を達成するため鋭意検討した結果、各層が織物組織を有する２層構造織物において、肌側に位置する層のカバーファクターＣＦを外気側に位置する層の
カバーファクターＣＦよりも低くし、かつこれらのＣＦを特定の範囲内とすることにより、肌側に位置する層がスペーサーの役割を果たすことにより、防透性と通気性とが同時に得られることを見出し、さらに鋭意検討を重ねることにより本発明に想到した。
As a result of intensive studies to achieve the above object, the present inventors have determined that the cover factor CF of the layer located on the skin side is the cover factor CF of the layer located on the outside air side in the two-layer structure fabric in which each layer has a woven structure. And by making these CFs within a specific range, the layer located on the skin side plays the role of a spacer, so that both permeability and air permeability can be obtained at the same time. The present invention has been conceived through extensive studies.
かくして、本発明によれば「各層が織組織を有する２層構造織物であって、各層のカバーファクターＣＦが互いに異なり、高ＣＦ側の層のカバーファクターＣＦ１が１０００〜２５００の範囲であり、一方、低ＣＦ側の層のカバーファクターＣＦ２が１５０〜１６００の範囲であり、かつ該ＣＦ１とＣＦ２とが下記式を満足することを特徴とする２層構造織物。」が提供される。

0.05 ≦ ((CF2 / (CF1 + CF2)) ≦ 0.45
その際、高ＣＦ側の層の織組織が平組織またはツイル組織であることが好ましい。一方、低ＣＦ側の層の織組織がギシャ組織であることが好ましい。かかる低ＣＦ側の層の厚みとしては、０．１〜５ｍｍの範囲であることが好ましい。また、高ＣＦ側の層および／または低ＣＦ側の層を構成する糸条に艶消し剤が１．０重量％以上含まれているとさらに良好な防透性が得られ好ましい。高ＣＦ側の層および／または低ＣＦ側の層を構成する糸条が撚り数１０００Ｔ／ｍ以下のマルチフィラメント糸条であることが好ましい。さらには、高ＣＦ側の層および／または低ＣＦ側の層を構成する糸条が仮撚捲縮加工糸であると、防透性が向上し好ましい。かかる２層構造織物の通気性としては、５０ｃｃ／ｃｍ２・ｓ以上であることが好ましい。また、防透性としてはΔＬで１２以下であることが好ましい。 At that time, the woven structure of the layer on the high CF side is preferably a flat structure or a twill structure.

以下、本発明の実施の形態について詳細に説明する。
まず、本発明の２層構造織物において、各層は織組織を有し、かつ各層のカバーファクターＣＦが互いに異なる。そして、高ＣＦ側の層のカバーファクターＣＦ１が１０００〜２５００（好ましくは、１５００〜２３００）の範囲であり、一方、低ＣＦ側の層のカバーファクターＣＦ２が１５０〜１６００（好ましくは、２００〜８００）の範囲である必要がある。さらには、該ＣＦ１とＣＦ２とが下記式を満足する必要がある。
０．０５≦（（ＣＦ２／（ＣＦ１＋ＣＦ２））≦０．４５
（より好ましくは、０．０８≦（（ＣＦ２／（ＣＦ１＋ＣＦ２））≦０．４）
（特に好ましくは、０．１≦（（ＣＦ２／（ＣＦ１＋ＣＦ２））≦０．３）
Hereinafter, embodiments of the present invention will be described in detail.
First, in the two-layer fabric of the present invention, each layer has a woven structure, and the cover factor CF of each layer is different from each other. The cover factor CF1 of the layer on the high CF side is in the range of 1000 to 2500 (preferably 1500 to 2300), while the cover factor CF2 of the layer on the low CF side is 150 to 1600 (preferably 200 to 800). ) Range. Furthermore, the CF1 and CF2 must satisfy the following formula.
0.05 ≦ ((CF2 / (CF1 + CF2)) ≦ 0.45
(More preferably, 0.08 ≦ ((CF2 / (CF1 + CF2)) ≦ 0.4)
(Particularly preferably, 0.1 ≦ ((CF2 / (CF1 + CF2)) ≦ 0.3)
なお、カバーファクターＣＦとは下記式により表されるものである。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
ただし、ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。
The cover factor CF is represented by the following formula.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).
本発明の２層構造織物において、かかるカバーファクターは特に重要である。かかるカバーファクターを有する２重構造織物を、低ＣＦ側の層が内側（肌側）になるように使用すると、肌側に位置する層がスペーサーの役割を果たすため、外部から入光した光が肌と高ＣＦ側の層との間（すなわち、低ＣＦ側の層）に閉じ込められ、優れた防透性が得られる。同時に、カバーファクターが前記の範囲内であれば、通気性が損なわれることがない。 Such a cover factor is particularly important in the two-layer fabric of the present invention. When a double structure woven fabric having such a cover factor is used so that the low CF side layer is on the inside (skin side), the layer located on the skin side acts as a spacer, so that light incident from the outside is not emitted. It is confined between the skin and the layer on the high CF side (that is, the layer on the low CF side), and excellent permeation resistance is obtained. At the same time, if the cover factor is within the above range, the air permeability is not impaired.
ここで、高ＣＦ側の層のカバーファクターＣＦ１が１０００よりも小さいと、織物を構成する糸条間で空隙ができやすく防透性が低下するため好ましくない。逆に、高ＣＦ側の層のカバーファクターＣＦ１が２５００よりも大きいと通気性が低下するため好ましくない。一方、低ＣＦ側の層のカバーファクターＣＦ２が１６００よりも大きいと、高ＣＦ側の層のカバーファクターＣＦ１との差が小さくなり、前記のスペーサー効果が得られにくく十分な防透性が得られず好ましくない。低ＣＦ側の層のカバーファクターＣＦ２が１５０よりも小さいと、低ＣＦ側の層で形成される空気層が保持されにくく、十分なスペーサー効果が得られにくくなるため好ましくない。また、ＣＦ２／（ＣＦ１＋ＣＦ２）が０．４５より大であれば、スペーサー効果が得られず十分な防透性が得られない。逆に、ＣＦ２／（ＣＦ１＋ＣＦ２）が０．０５よりも小さいと製造が困難となるため好ましくない。 Here, when the cover factor CF1 of the layer on the high CF side is smaller than 1000, voids are easily formed between the yarns constituting the woven fabric, and the permeability is not preferable. On the contrary, if the cover factor CF1 of the layer on the high CF side is larger than 2500, the air permeability is lowered, which is not preferable. On the other hand, if the cover factor CF2 of the layer on the low CF side is larger than 1600, the difference from the cover factor CF1 of the layer on the high CF side becomes small, and the above-mentioned spacer effect is difficult to obtain and sufficient permeability is obtained. Not preferable. If the cover factor CF2 of the layer on the low CF side is smaller than 150, the air layer formed by the layer on the low CF side is difficult to be retained, and it is difficult to obtain a sufficient spacer effect. On the other hand, if CF2 / (CF1 + CF2) is larger than 0.45, the spacer effect cannot be obtained and sufficient permeation resistance cannot be obtained. On the contrary, if CF2 / (CF1 + CF2) is smaller than 0.05, the production becomes difficult, which is not preferable.
各層の織物組織としては特に限定されないが、高ＣＦ側の層の織組織としては、平組織、ツイル組織など組織点の多い織組織が、織構造が安定であり防透性の点で好適である。一方、低ＣＦ側の層は、表面層と肌との距離を一定以上に保つスペーサーの役割を果たす層であるため、ギシャ組織（緯糸１本ごとに、隣接の経糸でからみ織りしたもの）が、容易に厚みを持たせることができ好適である。該低ＣＦ側の層の厚みとしては、０．１〜５ｍｍ（特に好ましくは０．５〜２．０ｍｍ）の範囲内であることが好ましい。 The woven structure of each layer is not particularly limited, but as the woven structure of the layer on the high CF side, a woven structure having many structure points such as a plain structure and a twill structure is preferable in terms of the stable woven structure and the permeation resistance. is there. On the other hand, the layer on the low CF side is a layer that acts as a spacer that keeps the distance between the surface layer and the skin at a certain level or more. Therefore, the Gishha structure (one weft entangled with adjacent warps) The thickness can be easily increased, which is preferable. The thickness of the low CF side layer is preferably in the range of 0.1 to 5 mm (particularly preferably 0.5 to 2.0 mm).
前記の高ＣＦ側の層と低ＣＦ側の層とは、高ＣＦ側の層を構成するおよび／または低ＣＦ側の層を構成する糸条により一部連結されている。ここで、高ＣＦ側の層と低ＣＦ側の層とが接着剤などで接着されたもものでは、十分な通気性が得られず好ましくない。 The high CF side layer and the low CF side layer are partially connected by yarns constituting the high CF side layer and / or the low CF side layer. Here, it is not preferable that the high CF side layer and the low CF side layer are bonded with an adhesive or the like because sufficient air permeability cannot be obtained.
本発明の２層構造織物を構成する繊維としては特に限定されず、ポリエステルやナイロンなどの合成繊維、アセテートなどの半合成繊維、レーヨン、キュプラなどの再生繊維、綿や麻などの天然繊維などいずれでもよい。なかでも、繊維強度や取扱いの容易さの点で、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、第３成分を共重合させたポリエステルなどのポリエステル系繊維が好ましく例示される。 The fiber constituting the two-layer structure fabric of the present invention is not particularly limited, and any of synthetic fibers such as polyester and nylon, semi-synthetic fibers such as acetate, regenerated fibers such as rayon and cupra, natural fibers such as cotton and hemp, etc. But you can. Of these, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, and polyester obtained by copolymerization of the third component are preferably exemplified in terms of fiber strength and ease of handling.
かかる繊維の繊維形態も特に限定されず、長繊維（マルチフィラメント糸条）でもよいし、短繊維でもよい。優れた防透性を得る上で、撚り数１０００Ｔ／ｍ以下（より好ましくは撚り数７００Ｔ／ｍ以下または無撚）のマルチフィラメント糸条が好適である。１０００Ｔ／ｍより高い撚りが施された長繊維や撚りが施された短繊維糸条では、経糸と緯糸とで形成される空隙が大きくなり、防透性が損なわれる恐れがある。かかる長繊維に、通常の仮撚捲縮加工が施されていると防透性がさらに向上し好ましい。 The fiber form of such fibers is not particularly limited, and may be long fibers (multifilament yarns) or short fibers. In order to obtain excellent permeation resistance, a multifilament yarn having a twist number of 1000 T / m or less (more preferably, a twist number of 700 T / m or less or no twist) is suitable. In a long fiber with a twist higher than 1000 T / m or a short fiber yarn with a twist, the gap formed by the warp and the weft becomes large, and the permeation resistance may be impaired. When such a long fiber is subjected to a normal false twist crimping process, the permeability is preferably improved.
該繊維の繊度は特に限定されないが、布帛強度や風合いの点や、総繊度で３３〜５００ｄｔｅｘ、単糸繊度で０．３〜６ｄｔｅｘの範囲が適当である。また、単糸の横断面形状も特に限定されるものではなく、通常の丸型だけでなく、扁平、三角、Ｙ型、Ｔ型、Ｕ型などの異型であってもよい。 The fineness of the fiber is not particularly limited, but a range of 33 to 500 dtex for the total fineness and 0.3 to 6 dtex for the single yarn fineness is appropriate. Further, the cross-sectional shape of the single yarn is not particularly limited, and may be not only a normal round shape but also a flat shape, a triangular shape, a Y shape, a T shape, a U shape, or the like.
なお、前記の繊維中には、微細孔形成剤、カチオン可染剤、着色防止剤、熱安定剤、蛍光増白剤、艶消し剤、着色剤、帯電防止剤、吸湿剤、無機微粒子等が１種又は２種以上含まれていてもよい。特に、艶消し剤が１．０重量以上（好ましくは、１．５〜３．５重量％）含まれていると、防透性がさらに向上し好ましい。 In the fibers, there are micropore forming agents, cationic dyes, anti-coloring agents, heat stabilizers, fluorescent whitening agents, matting agents, coloring agents, antistatic agents, hygroscopic agents, inorganic fine particles, and the like. 1 type or 2 or more types may be contained. In particular, when the matting agent is contained in an amount of 1.0% or more (preferably 1.5 to 3.5% by weight), the permeation resistance is further improved.
本発明の２層構造織物において、高ＣＦ側の層を構成する繊維と低ＣＦ側の層を構成する繊維が同じであってもよいし異なっていてもよいが、製造の容易さの点で同じであることが好ましい。 In the two-layer fabric of the present invention, the fibers constituting the high CF side layer and the fibers constituting the low CF side layer may be the same or different, but in terms of ease of manufacture Preferably they are the same.
本発明の２層構造織物は、１ビームまたは２ビームを有する通常の織機を用いて、各層を構成する糸条が一部互いに交錯するよう連結させて２層構造織物を製織し、その際、各層のカバーファクターを前記の特定範囲内とすることにより容易に製造することができる。 The two-layer structure fabric of the present invention is woven into a two-layer structure fabric by using a normal loom having one beam or two beams, and the yarns constituting each layer are partially connected to each other. It can be easily manufactured by setting the cover factor of each layer within the specific range.
かくして得られた２層構造織物を、低ＣＦ側の層が内側（肌側）に位置するように使用すると、外部から高ＣＦ側の層を透過して入光した光は肌で反射された後、低ＣＦ側の層のスペーサー効果により、肌と高ＣＦ側の層との間（すなわち、低ＣＦ側の層）に閉じ込められ優れた防透性が得られる。かかる防透性としては、ＪＩＳ Ｚ ８７２９−１９９４、Ｌ＊ａ＊ｂ＊表色系において、供試織物を白色板上に載置したときのＬ＊値（Ｌ＊ ｗと記す）と、それと黒色板上に載置したときのＬ＊値（Ｌ＊ ｂと記す）との差ΔＬ（＝Ｌ＊ ｗ−Ｌ＊ ｂ）で１２以下（より好ましくは５〜１１）であることが好ましい。さらには、高ＣＦ側の層と低ＣＦ側の層のカバーファクターが前記の範囲内であると通気性が損なわれることもない。かかる通気性としては、５０ｃｃ／ｃｍ２・ｓ以上（より好ましくは、６０〜５００ｃｃ／ｃｍ２・ｓ、特に好ましくは７０〜１００ｃｃ／ｃｍ２・ｓ）であることが好ましい。 When the two-layer structure woven fabric thus obtained was used so that the low CF side layer was located on the inner side (skin side), the light transmitted through the high CF side layer from the outside was reflected by the skin. After that, due to the spacer effect of the low CF side layer, it is confined between the skin and the high CF side layer (that is, the low CF side layer), and excellent permeability is obtained. As such permeation resistance, in JIS Z 8729-1994, L * a * b * color system, L * value (denoted as L * w ) when the test fabric is placed on a white plate, The difference ΔL (= L * w− L * b ) from the L * value (denoted as L * b ) when placed on a black plate is preferably 12 or less (more preferably 5 to 11). Further, if the cover factor of the high CF side layer and the low CF side layer is within the above range, the air permeability is not impaired. The air permeability is preferably 50 cc / cm 2 · s or more (more preferably 60 to 500 cc / cm 2 · s, particularly preferably 70 to 100 cc / cm 2 · s).
かかる２層構造織物には、アルカリ減量加工や常法の染色仕上げ加工が施されてもよい。さらには、常法の吸水加工、撥水加工、起毛加工、紫外線遮蔽あるいは制電剤、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤、マイナスイオン発生剤等の機能を付与する各種加工を付加適用してもよい。 Such a two-layer fabric may be subjected to alkali weight loss processing or conventional dye finish processing. Furthermore, functions such as conventional water absorption processing, water repellency processing, brushed processing, ultraviolet shielding or antistatic agent, antibacterial agent, deodorant agent, insect repellent agent, phosphorescent agent, retroreflective agent, negative ion generator and the like are added. Various processing may be additionally applied.
