Description
本発明は、通気性と防透性とを同時に有する織物に関する。 The present invention relates to a fabric having both air permeability and air permeability.
ユニホーム、ブラウス、シャツ、スポーツ用衣服等の用途では、通気性と着用時に肌が透けて見えない防透性とが同時に求められることがある。しかしながら、通気性と防透性とは、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、隣り合う糸条間に空隙ができ、この空隙から肌が透けて充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密度を高くすると、空気の通りが阻害されて通気性が低下してしまう。 In applications such as uniforms, blouses, shirts, and sports clothing, there is a case where both air permeability and anti-permeation property, in which the skin is not visible when worn, are required at the same time. However, breathability and permeability are usually contradictory properties. For example, when the woven / knitting density of the fabric is reduced to obtain air permeability, voids are formed between adjacent yarns, and the skin is transparent through the voids, and sufficient permeability cannot be obtained. Conversely, when the woven / knitting density of the fabric is increased in order to obtain the permeability, the passage of air is hindered and the air permeability is reduced.
上記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、やはり織編密度を上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 the above contradictory characteristics, for example, Patent Literature 1 proposes that a matting agent is sufficiently kneaded into fibers and a fiber structure is formed using the fibers. According to this method, the light transmitted through the fiber itself is scattered by the matting agent, so that the light transmission is improved to some extent. However, since the passage of light from between the yarns is inevitable, there is a problem that the woven / knitting density must be increased and the air permeability is reduced.
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、この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。 On the other hand, Patent Document 2 proposes a woven fabric having a two-layer structure. This two-layer woven fabric is intended to improve antistatic properties and sweat absorption properties by attaching a water-absorbing polymer to the woven fabric. However, it was not satisfactory in terms of permeability and air permeability.
本発明は、上記の背景技術に鑑みてなされたものであって、その目的は、通気性と防透性とを同時に有する織物を提供することにある。 The present invention has been made in view of the above background art, and an object of the present invention is to provide a fabric having both air permeability and air permeability.
前記課題を解決するために本願発明は、６枚メッシュ組織と、平織組織と、経糸４本と緯糸４本が交差しない組織とを含み、経糸および緯糸の少なくとも一部に撚糸を用いたことを特徴としている。 In order to solve the above problems, the present invention includes a six-mesh structure, a plain weave structure, a structure in which four warps and four wefts do not intersect, and uses a twisted yarn for at least a part of the warp and the weft.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, various changes and modifications can be made without departing from the technical scope of the present invention.
FIG. 1 is a view showing a plain weave structure which is one of the weave structures constituting the woven fabric of the present invention, and FIG. 2 is a 4-4 floating structure (warp yarn 4) which is one of the weave structures constituting the woven fabric of the present invention. FIG. 3 is a diagram showing a six-mesh structure which is one of the weaving structures constituting the woven fabric of the present invention.
図４は、図１、図２および図３の織組織から構成される本発明の織物の織組織の一実施形態を示す図である。本発明の織物は、通気性と防透性とを同時に有することを特徴としており、それらの特性について説明する。 FIG. 4 is a diagram showing an embodiment of the woven structure of the woven fabric of the present invention composed of the woven structures of FIGS. 1, 2 and 3. The woven fabric of the present invention is characterized by having both air permeability and air permeability, and the characteristics thereof will be described.
本発明の織物の通気度は、快適性を実感するためにはＪＩＳ １０９６ ８．２７．１ Ａ法（ＪＩＳ２００４年版）に定めるフラジール法にて測定される通気量が６０ｃｃ／ｃｍ２・s 以上あることが好ましく、夏場の高温多湿条件において快適性を得るためには通気量が１００ｃｃ／ｃｍ２・s 以上であり、さらに好ましくは１２０ｃｃ／ｃｍ２・s 以上あればよい。通気量は、高ければ高いほど衣服内と外気の交換が行いやすく快適であるが、逆に通気量が高すぎると織物の隙間が大きいことを意味し、防透性が得られないことがあり、分光透過率の調整と逆方向に、組織、繊維種、織物密度等を調整することより、分光透過率と通気量を両立させることが重要である。 Regarding the air permeability of the woven fabric of the present invention, the air permeability measured by the Frazier method specified in JIS 1096 8.27.1 A method (JIS 2004 version) is 60 cc / cm 2 · s or more in order to feel comfort. It is preferable that the ventilation rate is 100 cc / cm 2 · s or more, more preferably 120 cc / cm 2 · s or more, in order to obtain comfort under high temperature and high humidity conditions in summer. The higher the ventilation rate, the easier it is to exchange the inside and outside of the clothes and the more comfortable it is.On the contrary, if the ventilation rate is too high, it means that the gap between the fabrics is large, and the permeability may not be obtained. It is important to balance the spectral transmittance and the air flow rate by adjusting the tissue, fiber type, woven fabric density, and the like in the opposite direction to the adjustment of the spectral transmittance.
ここで、本発明でいう防透性とは、光の透過率によって表される。本発明の織物は、波長領域が４００〜７８０ｎｍにおける可視光線の分光透過率が５０％以下であることが重要である。分光透過率が５０％より大きいと織物の隙間が大きく可視光線が通り過ぎるため、衣服とした場合に透け感が大きく感じられる。さらに分光透過率は４０％以下が好ましく、より好ましくは３０％以下である。ただし、分光透過率が５％を下回ると透け感がない代わりに夏物衣料としは重厚感が生じてしまうことがある。 Here, the transparency as referred to in the present invention is represented by light transmittance. It is important that the woven fabric of the present invention has a spectral transmittance of visible light of 50% or less in a wavelength region of 400 to 780 nm. If the spectral transmittance is greater than 50%, the gap between the woven fabrics is large and visible light passes therethrough, so that the sense of sheer feeling is large when the garment is used. Further, the spectral transmittance is preferably 40% or less, more preferably 30% or less. However, if the spectral transmittance is less than 5%, there will be no sense of sheer, but a profound feeling may occur for summer clothing.
分光透過率を調整するためには、繊維の種類、繊度および織物密度を選択すること、すなわち、透過率が低く、かつ太い繊度の繊維を使用すれば光の透過を抑えることができる。また、織物組織としては、同じ織物密度であれば、組織ズレ（メッシュ効果）が大きくなれば、結果として透過しやすくなる。一方、織物密度は高ければ組織ズレを起こしにくくなり、分光透過率を低くすることができる。 In order to adjust the spectral transmittance, the type of the fiber, the fineness, and the density of the fabric are selected. That is, light transmission can be suppressed by using a fiber having a low transmittance and a large fineness. Further, as for the woven fabric structure, if the woven fabric density is the same, if the structure deviation (mesh effect) increases, the woven fabric is easily transmitted as a result. On the other hand, if the density of the woven fabric is high, the misalignment is less likely to occur, and the spectral transmittance can be lowered.
ここで分光透過率とは、分光光度計を用いて測定することができる。分光光度計は光源から出た光を波長ごとに分ける部分（分光部）と、分けた光を試料に当てて光の弱くなる程度を測定する部分（光度計）から構成される。 Here, the spectral transmittance can be measured using a spectrophotometer. The spectrophotometer is composed of a part that separates the light emitted from the light source for each wavelength (spectroscopy part) and a part that measures the degree of weakening of the light by applying the separated light to a sample (photometer).
本発明の織物のカバーファクターは、２０００から２６００の範囲であることが好ましい。カバーファクターが２０００未満では通気性は向上するものの過度に粗な構造となり、透け感が顕著になる。一方、カバーファクターが２６００を超えると透け感はなくなるものの、通気性が不足する。 The cover factor of the fabric of the present invention is preferably in the range of 2,000 to 2,600. When the cover factor is less than 2,000, the air permeability is improved, but the structure becomes excessively rough, and the sense of sheer becomes remarkable. On the other hand, when the cover factor exceeds 2600, the sense of sheerness is lost, but the air permeability is insufficient.
ここでカバーファクターは、次式にて表される。
カバーファクター＝Ｎ１（Ｄ１）１／２＋Ｎ２（Ｄ２）１／２
（式中、Ｎ１は経糸密度（本／２．５４ｃｍ）、Ｎ２は緯糸密度（本／２．５４ｃｍ）、Ｄ１は経糸の繊度（ｄｔｅｘ）、Ｄ２は緯糸の繊度（ｄｔｅｘ）をそれぞれ表す。）
Here, the cover factor is expressed by the following equation.
Cover factor = N1 (D1) 1/2 + N2 (D2) 1/2
(In the formula, N1 represents the warp density (book / 2.54 cm), N2 represents the weft density (book / 2.54 cm), D1 represents the fineness (dtex) of the warp, and D2 represents the fineness (dtex) of the weft.)
経糸および緯糸に用いられる糸の総繊度は５６ｄｔｅｘ〜３３０ｄｔｅｘであることが好ましく、単糸繊度は０．７７ｄｔｅｘ〜３．４８ｄｔｅｘであることが好ましい。織物に適切な強度と風合いを付与するためである。単糸の横断面形状は限定されるものでなく、丸型だけでなく、扁平、三角形、Ｙ型、Ｔ型、Ｕ型などの異形、中空糸であってもよい。 The total fineness of the yarns used for the warp and the weft is preferably from 56 dtex to 330 dtex, and the single yarn fineness is preferably from 0.77 dtex to 3.48 dtex. This is for imparting appropriate strength and texture to the woven fabric. The cross-sectional shape of the single yarn is not limited, and may be not only a round shape but also a flat, triangular, Y-shaped, T-shaped, U-shaped or other irregular shape, or a hollow fiber.
本発明の織物を構成する繊維としては、綿や麻等の天然繊維、ウール等の動物繊維、ポリエステルやナイロン等の合成繊維、アセテート等の半合成繊維、レーヨン、キュプラ等の再生繊維などを用いることができる。また、繊維形態も紡績糸やフィラメント等、特に限定されず、各種素材を混紡した紡績糸も使用できる。 As the fibers constituting the woven fabric of the present invention, natural fibers such as cotton and hemp, animal fibers such as wool, synthetic fibers such as polyester and nylon, semi-synthetic fibers such as acetate, and regenerated fibers such as rayon and cupra are used. be able to. The fiber form is not particularly limited, such as a spun yarn or a filament, and a spun yarn obtained by blending various materials can be used.
優れた通気性と防透性を得るうえで、撚り数１８００Ｔ／ｍ以下のマルチフィラメント糸条が好ましい。１８００Ｔ／ｍより高い撚りが施された長繊維や短繊維糸条では、経糸と緯糸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。一方、撚り数が３００Ｔ／ｍより少なくなると、糸の膨らみにより経糸と緯糸の空隙が低下し、通気性が悪化するという不都合がある。 In order to obtain excellent air permeability and permeability, a multifilament yarn having a twist number of 1800 T / m or less is preferable. In a long fiber or a short fiber yarn having a twist higher than 1800 T / m, a void formed by a warp and a weft becomes large, and there is a possibility that permeability may be impaired. On the other hand, if the number of twists is less than 300 T / m, the space between the warp and the weft decreases due to the swelling of the yarn, and the air permeability deteriorates.
本発明の織物は、メッシュ組織による高い通気性と、経糸４本と緯糸４本が交差しない組織（「経糸と緯糸が１本おきに交差する」平織ではなく、「経糸と緯糸のいずれかが他方の上を１本、下を２〜３本通過することを繰り返し、経糸と緯糸の交差する組織点が斜めの文様を形成する」綾織でもなく、「経糸と緯糸どちらかの糸の浮きが非常に少なく、経糸または緯糸のみが表に表れているように見える、交差する組織が最も少ない」朱子織でもなく、４本の経糸と４本の緯糸がそれぞれほぼ等間隔で配置され、この４本の経糸の下に潜り込むように４本の緯糸が配置され、あるいは、４本の緯糸の下に潜り込むように４本の経糸が配置される組織）によって、防透性を得ることができる。 The woven fabric of the present invention has a high air permeability by a mesh structure and a structure in which four warps and four wefts do not intersect (a plain weave in which “a warp and a weft intersect every other”, but “one of a warp and a weft” It repeats passing one line above the other and two or three lines below, and the texture points where the warp and weft intersect form an oblique pattern. Very few, only warp or weft appear to be visible on the surface, least intersecting structure "Not a satin weave, four warp yarns and four weft yarns are arranged at almost equal intervals, respectively. A structure in which four wefts are arranged so as to be sunk under a warp, or four warps are arranged so as to be sunk under four wefts) can provide the waterproofness.
さらに、経糸４本と緯糸４本が交差しない組織は、４本の経糸の下に潜り込むように４本の緯糸が配置されるか、４本の緯糸の下に潜り込むように４本の経糸が配置されることによって、当該交差しない組織の裏面部（肌当たり面）では４本の緯糸が直接肌に接触することによって、肌面に直接接触する糸本数が少なくなるので、風合いが改善され、清涼感を得ることができる。図５の矢示部分は、直接肌に接触する４本の緯糸で、他の糸との浮きの差を示す拡大図（５００倍）である。 Further, in a structure in which four warps and four wefts do not intersect, four wefts are arranged so as to sunk under four warps, or four warps are sunk under four wefts. By being arranged, the four wefts directly contact the skin on the back surface (skin contact surface) of the non-intersecting structure, so that the number of yarns directly contacting the skin surface is reduced, so that the texture is improved. Refreshing feeling can be obtained. The arrowed part in FIG. 5 is an enlarged view (500 times) showing the difference in float between the four wefts that directly contact the skin and the other yarns.
メッシュ組織（模紗組織）は、組織ズレによりその中心部に隙間（穴あき）ができる組織で、高い通気性が実現できる。その最小組織が６枚メッシュ組織（経糸６本と緯糸６本で構成される）である。メッシュ組織は高い通気性が実現できるが、穴あきのために防透性が劣る。経糸４本と緯糸４本が交差しない組織は、４本の経糸と４本の緯糸がそれぞれ隙間なく並んで配置され、４本の経糸と４本の緯糸が直角に交わるように表裏面に配置される。経糸同士または緯糸同士が隙間なく並んで配置されるため、防透性が優れている。また、染色加工時の熱により経糸および緯糸を構成する繊維が収縮すると、経糸と緯糸が交差していないため、全体として膨らみ、肌当たり面に対してベタ当たり（肌に対して直接接触する糸の面積が大きいこと）が防止されるという効果がある。図４に示すように、６枚メッシュ組織と経糸４本と緯糸４本が交差しない組織が対角線上に配置され、その間を平織組織が埋めることによって、６枚メッシュ組織の隙間（穴あき）により高い通気性を得、経糸４本と緯糸４本が交差しない組織により優れた防透性を得、さらに、組織裏面で肌に接触するのは４本の緯糸であって、肌に接触する織組織の面積が少ないので肌触りがよく、着用時の感触の良好な快適衣料を実現することができる。 The mesh structure (pattern structure) is a structure in which a gap (perforation) is formed at the center due to a structure deviation, and high air permeability can be realized. The minimum design is a six-mesh design (consisting of six warps and six wefts). The mesh structure can realize high air permeability, but has poor permeability due to the perforation. In the structure in which four warps and four wefts do not intersect, four warps and four wefts are arranged side by side without any gap, and four warps and four wefts are arranged on the front and back surfaces so that they intersect at right angles. Is done. Since the warp yarns or the weft yarns are arranged side by side without any gap, the waterproofness is excellent. Also, when the fibers constituting the warp and the weft shrink due to the heat during the dyeing process, the warp and the weft do not intersect, so that they swell as a whole and come into solid contact with the skin contact surface (the yarn that directly contacts the skin). Is large). As shown in FIG. 4, a structure in which the six-mesh structure, four warp yarns, and four weft yarns do not intersect is arranged diagonally, and a plain weave structure fills the space therebetween, thereby forming a gap (perforated) between the six-mesh structure. High permeability is obtained, and excellent waterproofness is obtained by a structure in which four warps and four wefts do not intersect. Further, the four wefts that come into contact with the skin on the back of the tissue are woven fabrics that come into contact with the skin. Since the area of the tissue is small, a comfortable garment having a good touch and a good feel when worn can be realized.
