Description
本発明は、マルチフィラメントまたは紡績糸からなる高密度織物に関し、さらに詳しくは、透過する物質量を制御できる高機能高密度織物に関するものである。 The present invention relates to a high-density fabric made of multifilaments or spun yarns, and more particularly to a high-performance high-density fabric that can control the amount of permeated material.
従来より、ダウンやフェザーなどの先鋭形状物質に対する耐突刺し性能を得るために、高密度織物は種々検討されてきたが、構造上、糸条同士の拘束力が強い平織構造が一般的に使われてきた。しかし、構造上および設備的限界から、織密度を一定の値より高めることは困難であり、織密度を高めると糸条の交錯点に生ずる糸条間の隙間が小さくなるため通気性が低下するなど、物質の透過性の制御には性能的な限界が生じる。この問題に対して、カレンダー加工にて繊維を織物平面方向に広げて糸条間の隙間の大きさを制御する手法、織物にウレタン等の膜をラミネートやコーティングする手法が挙げられる（たとえば、特許文献１参照）。しかし、ラミネートする微多孔膜は通気性さえも著しく低下し、樹脂コーティングでは膜厚ムラにより均一な特性を得ることは難しく、適度な物質透過性があるとは言えない。 Conventionally, various high-density fabrics have been studied in order to obtain puncture-proof performance against sharp-shaped materials such as down and feathers, but a plain weave structure with strong binding force between yarns is generally used. I have been. However, due to structural and equipment limitations, it is difficult to increase the weaving density above a certain value. When the weaving density is increased, the gap between the yarns at the intersection of the yarns becomes smaller and the air permeability decreases. There are performance limitations in controlling the permeability of substances. In order to solve this problem, there are a method of controlling the size of the gap between the yarns by spreading the fibers in the fabric plane direction by calendering, and a method of laminating or coating a film such as urethane on the fabric (for example, patents) Reference 1). However, even the microporous film to be laminated has a significantly reduced air permeability, and it is difficult to obtain uniform characteristics due to film thickness unevenness in the resin coating, and it cannot be said that there is an appropriate substance permeability.
一方、綾織や朱子織などの場合、平織より織密度を高密度化できるが、経糸と緯糸の交錯点が少なければ、先鋭形状物が織物に差し込まれると糸条間のずれが生じやすいため突き抜けやすくなる。また、洗濯等の物理的な揉みや摩擦によって構造は崩れやすいため、物質透過性が変動する。この問題に対して、後加工にて糸を収縮させて織密度を高める手法や、平織と同様にカレンダー加工やウレタン膜等のラミネートやコーティングする手法が挙げられる（たとえば、特許文献２参照）。しかし、加工時の揉みや摩擦により構造が崩れ、物性値のバラツキが増大する。また、平織と同様に微多孔膜ラミネートでは通気性が著しく低下し、樹脂コーティングでは膜厚ムラにより均一な特性を得ることは難しく、物質透過性の制御は困難である。 On the other hand, in the case of twill weave and satin weave, weaving density can be higher than plain weave. It becomes easy. Moreover, since the structure tends to collapse due to physical stagnation and friction such as washing, the material permeability varies. In order to solve this problem, there are a method of shrinking the yarn by post-processing and increasing the woven density, and a method of laminating and coating such as calendering and urethane film as in the case of plain weaving (for example, see Patent Document 2). However, the structure collapses due to stagnation and friction during processing, and the variation in physical properties increases. In addition, as with the plain weave, the air permeability is remarkably lowered in the microporous membrane laminate, and it is difficult to obtain uniform characteristics due to uneven film thickness in the resin coating, and it is difficult to control the material permeability.
本発明は上記背景技術に鑑みなされたものであり、先鋭形状物質の耐突刺し性と各分野で要求される通気性、耐水圧など布帛を通過する物質量を制御できる高機能高密度織物を提供することにある。 The present invention has been made in view of the above-described background art, and provides a high-performance high-density fabric capable of controlling the amount of material passing through the fabric, such as the puncture resistance of a sharp-shaped material and the air permeability and water pressure required in each field. It is to provide.

本発明によれば、従来にない織物構造が発現され、先鋭形状物質の耐突刺し性と各分野で要求される通気性、耐水圧など布帛を通過する物質量を制御できる高機能高密度織物が得られる。 ADVANTAGE OF THE INVENTION According to this invention, the high-functional high-density fabric which can control the amount of materials which can pass through cloth, such as the puncture resistance of a sharp-shaped substance, the air permeability required in each field | area, and a water pressure resistance, expresses the textile structure which is not in the past. Is obtained.
以下、本発明の高密度織物について、詳細に説明する。
本発明の高密度織物で用いられる糸の形態は何ら限定されるものではなく、マルチフィラメントや紡績糸が適用されるが、流体の透過性を抑制するにはマルチフィラメントが好ましい。また、マルチフィラメントは仮撚加工の捲縮やエアー加工により嵩高性を有していても良く、通気性や耐水圧を調整する目的として、フィラメント数や繊度、単繊維断面を任意に選択できる。特に、耐水圧を向上させる手段として、フィラメント数の増加やフィラメントの細繊度化が適している。単繊度断面は丸、三角、扁平、中空などの異型断面糸や割繊糸などを用いることも効果的である。糸の材質としては、綿や羊毛、麻のような天然繊維や、ポリエステルやナイロン、アクリルなどの合成繊維、セルロース、レーヨンなどの再生繊維、半合成繊維などのいずれかを選択することができるが、糸物性が比較的安定な合成繊維が好ましい。要求機能に応じて、フッ素、ポリフェニレンサルファイド、アラミドなどの高性能繊維を用いてもよく、２種以上の糸を交織しても問題ない。
Hereinafter, the high-density fabric of the present invention will be described in detail.
The form of the yarn used in the high-density fabric of the present invention is not limited in any way, and multifilament and spun yarn are applied, but multifilament is preferable for suppressing fluid permeability. Moreover, the multifilament may have bulkiness by crimping of false twisting or air processing, and the number of filaments, fineness, and single fiber cross section can be arbitrarily selected for the purpose of adjusting air permeability and water pressure resistance. In particular, increasing the number of filaments and reducing the fineness of the filaments are suitable as means for improving the water pressure resistance. It is also effective to use irregular cross-section yarns such as round, triangular, flat, hollow, or split yarns for the single fineness cross section. The material of the yarn can be selected from natural fibers such as cotton, wool and hemp, synthetic fibers such as polyester, nylon and acrylic, recycled fibers such as cellulose and rayon, and semi-synthetic fibers. A synthetic fiber having a relatively stable yarn physical property is preferable. Depending on the required function, high-performance fibers such as fluorine, polyphenylene sulfide, and aramid may be used, and there is no problem even if two or more kinds of yarns are interwoven.
本発明の高密度織物は、カバーファクタ（ＣＦ）は２７００以上が好ましく、２９００〜４０００の範囲であればより好ましい。カバーファクタは２７００より小さいと、糸条間の隙間が大きくなるため先鋭形状物質が突き抜けやすくなる。一方、カバーファクタは４０００よりも大きいと、糸条間の隙間が小さくなるため物質透過性の低下が起こる。 In the high-density fabric of the present invention, the cover factor (CF) is preferably 2700 or more, and more preferably in the range of 2900 to 4000. When the cover factor is smaller than 2700, the gap between the yarns becomes large, so that the sharp-shaped substance can easily penetrate. On the other hand, when the cover factor is larger than 4000, the gap between the yarns becomes small, and the material permeability is lowered.
カバーファクタ（ＣＦ）は下記式（１）で算出した。 The cover factor (CF) was calculated by the following formula (1).

D WARP is the warp finish weaving density [25.4mm]
F WEFT is the weft actual fineness [dtex],
D WEFT is a weft finish density [lines / 25.4 mm].
本発明の高密度織物において、カバーファクタ（ＣＦ）と式（２）から算出される見かけカバーファクタ（ＣＦａ）との比ＣＦａ／ＣＦが０．５以上０．８以下であることは重要である。ＣＦａ／ＣＦが０．８以上であると、平織りや糸条の交錯点の多い綾織り以外の組織が困難となり、交錯点に生ずる糸条間の隙間が小さくなるため物質透過性が低下する。ＣＦａ／ＣＦが０．５未満の場合、交錯点の少ない組織となるため、先鋭形状物質に対する耐突刺し性が低くなる。上記範囲であれば、先鋭形状物質の突き抜けが抑制でき、且つ適度な物質透過性を確保することができる。 In the high-density fabric of the present invention, it is important that the ratio CFa / CF between the cover factor (CF) and the apparent cover factor (CFa) calculated from the formula (2) is 0.5 or more and 0.8 or less. . When CFa / CF is 0.8 or more, a structure other than a plain weave or a twill weave having many intersecting points of yarns becomes difficult, and a gap between yarns formed at the intersecting points becomes small, so that material permeability is lowered. When CFa / CF is less than 0.5, the structure has few crossing points, so that the puncture resistance to a sharp-shaped substance is lowered. If it is the said range, penetration of a sharp-shaped substance can be suppressed and moderate substance permeability can be ensured.
見かけカバーファクタの算出方法について下記に説明する。 The method for calculating the apparent cover factor will be described below.
図１は、変化組織をもつ織物の拡大写真（１５０倍）であり、図２は、見かけカバーファクタの求め方を説明するために、図１の要部を拡大した模式図である。図２に示すように、経糸および緯糸に平行な線を描いて単位面積の正方形（細線で囲まれた図形）を得、その正方形の内部にある経糸の織構造の山部を数え、その正方形から少しでもはみ出した山部は０．５とする。そのようにして図１の正方形の内部にある山部を数えると、２１（単位数ＣＷＡＲＰ）になる。その単位数ＣＷＡＲＰから２５．４ｍｍ四方の山部の数（ＭＷＡＲＰ）を求める。経糸が緯糸との交錯する点数をｎＷＡＲＰとすると、ｎＷＡＲＰは以下の式（３）のように求められる。 FIG. 1 is an enlarged photograph (150 times) of a woven fabric having a change structure, and FIG. 2 is a schematic diagram in which a main part of FIG. 1 is enlarged to explain how to obtain an apparent cover factor. As shown in FIG. 2, a line parallel to the warp and weft is drawn to obtain a unit area square (figure surrounded by fine lines), and the peak of the woven structure of the warp inside the square is counted. The mountain part that protrudes even a little is 0.5. Thus, if the peak part in the square of FIG. 1 is counted, it will be 21 (unit number CWARP ). The number (M WARP ) of 25.4 mm squares is obtained from the unit number C WARP . When the number of points that warp is interlaced with the weft and n WARP, n WARP is obtained as the following equation (3).
同様に、緯糸の織構造の山部は、図１の正方形の内部にある山部の数（単位数ＣＷＥＦＴ）、２５．４ｍｍ四方の山部の数（ＭＷＥＦＴ）から算出され、緯糸が経糸と交錯する点数ｎＷＥＦＴは以下式（４）のように求められる。 Similarly, the ridges of the weft structure are calculated from the number of ridges (unit number C WEFT ) and the number of ridges 25.4 mm square (M WEFT ) inside the square of FIG. The number n WEFT that intersects with the warp is obtained as shown in the following formula (4).
経糸の実繊度［ｄｔｅｘ］をＦＷＡＲＰ、緯糸の実繊度［ｄｔｅｘ］をＦＷＥＦＴとすると、式（３）、（４）で算出された交錯点数を用いて、見かけカバーファクタ（ＣＦａ）が算出される。 Actual fineness of the warp [dtex] and F WARP, when the actual fineness of the weft yarn [dtex] and F WEFT, equation (3), using the interlaced points calculated in (4), calculates the apparent cover factor (CFa) is Is done.
本発明の高密度織物の織組織は、経糸・緯糸共に浮き本数が４本未満であることが好ましい。例えば図３ａに示す織組織（２／３綾織）であれば、経糸条Ａは緯糸条ｃから緯糸条ｅと交錯する間は布帛下側で浮き糸として存在しており、浮き本数は緯糸条を跨ぐ本数となるため３本となる。また、図３ｂに示す織組織（５枚朱子織）であれば、緯糸条ｂは経糸条Ａから経糸条Ｄと交錯する間は布帛上側で浮き糸として存在しており、浮き本数は経糸条を跨ぐ本数となるため４本となる。４糸条以上同じ側に存在すると直交する糸条との交錯点数が減少するため、洗濯等の揉みや擦過により糸条の位置がずれてしまい、糸条間から先鋭形状物質が突き抜けやすくなる。 The woven structure of the high-density fabric of the present invention preferably has a number of floats of less than 4 for both warp and weft. For example, in the woven structure (2/3 twill weave) shown in FIG. 3a, the warp yarn A exists as a floating yarn under the fabric while it intersects with the weft yarn c to the weft yarn e, and the number of floats is the weft yarn. Since the number crosses the number, it becomes three. In the woven structure (five satin weaves) shown in FIG. 3b, the weft yarn b exists as a floating yarn on the upper side of the fabric while it intersects with the warp yarn A to the warp yarn D, and the number of floats is the warp yarn. Since the number crosses the number, it becomes 4. When four or more yarns are present on the same side, the number of crossing points with orthogonal yarns is reduced, so that the position of the yarns is shifted due to stagnation or rubbing such as washing, and the sharp-shaped substance easily penetrates between the yarns.
また、隣り合う両方の糸条と直交する糸条を挟んで反対側に存在する確率は１５％以上が好ましい。例えば図４ａに示す織組織の糸条ＡのＡ１地点であれば、点線部での断面図は図４ｂとなるが、Ａ１地点で隣接する両側の糸条ＢとＣに対し、直交する１本の糸条Ｄを挟んで反対の位置（Ａは布帛下側、ＢとＣは布帛上側）に存在している。Ａ１地点のような織構造は、糸条Ａと直交する糸条と平行方向の応力に対し、織物構造として最も拘束力が働く構造となる。 Further, the probability of existing on the opposite side across the yarn orthogonal to both adjacent yarns is preferably 15% or more. For example, if it is A1 point of the yarn A of the woven structure shown in FIG. 4a, the cross-sectional view at the dotted line portion is FIG. 4b, but one piece orthogonal to the yarns B and C on both sides adjacent to the A1 point. Are present at opposite positions (A is the fabric lower side, B and C are the fabric upper side). The woven structure such as the point A1 is a structure in which the binding force works most as a woven structure against a stress parallel to the yarn orthogonal to the yarn A.
更には、経糸と緯糸共に織物表面もしくは裏面のどちらか一方に偏って多く存在すると織物のシワやカールの原因となるため、経糸・緯糸ともに直交する糸条の上側に対して下側に存在する比率が６５％以上１５０％以下であることが好ましく、１００％であればより好ましい。図４ａの織組織を用いて算出すると、上側の糸１９箇所、下側の糸３０箇所、上側に対して下側に存在する比率は約１５８％となる。 Furthermore, if both the warp and weft are biased to either the front or back of the fabric, the warp and curl of the fabric will be caused. Therefore, both the warp and weft are on the lower side of the perpendicular yarn. The ratio is preferably 65% or more and 150% or less, and more preferably 100%. When calculated using the woven structure of FIG. 4a, the ratio of the upper 19 yarns, the lower 30 yarns, and the lower side with respect to the upper side is about 158%.
本発明の高密度織物はレピア織機、エアージェット織機、ウォータージェット織機、フライシャトル織機、グリッパ織機から選択されるいずれかで製織することできる。そして、高付加価値を付与できる多色自由交換装置を有した織機、変化組織に対応することが可能なドビー装置を有した織機などは更に好ましく使用することができる。中でも、生産性の高く、製造コストが比較的安価なドビー装置を有するウォータージェット織機が好ましい。 The high-density fabric of the present invention can be woven by any one selected from a rapier loom, an air jet loom, a water jet loom, a fly shuttle loom, and a gripper loom. Further, a loom having a multicolor free exchange device capable of giving high added value, a loom having a dobby device capable of dealing with a changed tissue, and the like can be more preferably used. Among these, a water jet loom having a dobby device with high productivity and relatively low manufacturing cost is preferable.
本発明の高密度織物の通気度は、用途に応じて適宜選択することができる。例えば、ダウンジャケット側地に用いる場合は、１ｃｃ／ｃｍ・ｓｅｃ以上あれば 着用時のムレ感を抑制することができる。上記通気度の測定は、ＪＩＳ Ｌ１０９６Ａ法 フラジール形法によるものとする。 本発明の高密度織物の耐水圧は、用途に応じて適宜選択することができる。特に、衣料用側地に用いる場合は、３００ｍｍＨｇ以上あれば軽度の雨でも側地裏側へ濡れがなく着用できる。上記耐水圧の測定は、ＪＩＳ Ｌ１０９２耐水度試験（静水圧法） Ａ法（低水圧法）によるものとする。 The air permeability of the high-density fabric of the present invention can be appropriately selected depending on the application. For example, when used on the down jacket side, the stuffiness when worn can be suppressed if it is 1 cc / cm · sec or more. The measurement of the said air permeability shall be based on JIS L1096A method fragile type method. The water pressure resistance of the high-density fabric of the present invention can be appropriately selected depending on the application. In particular, when used for clothing side ground, if it is 300 mmHg or more, it can be worn without getting wet on the back side of the side even in light rain. The measurement of the water pressure resistance is based on the JIS L1092 water resistance test (hydrostatic pressure method) A method (low water pressure method).
本発明の高密度織物の好適な衣料品の事例として、フィッシング、登山衣などのアウトドアウェア、スキーウェア、アスレチックウェア、ゴルフウェアなどのスポーツウェア、カジュアルウェア、レインコート、ユニフォーム、屋外作業衣などがあるが、特にダウンジャケットやウィンドブレーカーの側地がより好ましい事例として挙げられる。ダウンジャケット側地であれば、先鋭形状物質であるダウンやフェザーに対する耐突刺性が高いため抜けを抑制でき、且つ通気性が１ｃｃ／ｃｍ・ｓｅｃ以上と高いためムレ感を低減することができる。ウィンドブレーカー側地であれば、耐水圧が５００ｍｍＨｇ以上と高いため防風性に優れた生地として提供できる。 Examples of suitable clothing of the high-density fabric of the present invention include outdoor wear such as fishing, mountaineering clothes, sportswear such as ski wear, athletic wear, golf wear, casual wear, raincoats, uniforms, outdoor work clothes, etc. In particular, a down jacket and a windbreaker side are more preferable examples. If it is a down jacket side place, since it has high puncture resistance against down and feathers, which are sharp-shaped substances, it can be prevented from coming out, and the air permeability is as high as 1 cc / cm · sec or more, so that the feeling of stuffiness can be reduced. If it is a windbreaker side land, since the water pressure resistance is as high as 500 mmHg or more, it can be provided as a fabric excellent in windproof properties.
本発明の高密度織物の好適な繊維製品の事例として、さらに布団や枕などの寝装側地、テント地、傘地、帽子、手袋などが挙げられる。寝装側地であれば、衣料用途の事例と同様に、綿や羽毛などの先鋭形状物質を保温材として用いた場合でも、高耐突刺性により保温材の抜けを抑制でき、さらには、高通気性を有するためムレを防ぐことができる。 Examples of suitable textile products of the high-density fabric of the present invention include bedding side areas such as futons and pillows, tents, umbrellas, hats, gloves and the like. In the case of bedding-side land, as in the case of apparel applications, even when a sharp-shaped material such as cotton or feather is used as the heat insulating material, it is possible to prevent the heat insulating material from falling out due to its high piercing resistance, Due to the air permeability, stuffiness can be prevented.
本発明の高密度織物の好適な産業用繊維製品の事例として、防護服、安全保護具、フィルター材などが挙げられる。防護服、安全保護具であれば、有刺植物や蜂の針、刃物などの先鋭形状物質が身の回りに存在しうる環境において、突刺されによる怪我の防止や装着時のムレ感を抑制でき、且つ引裂強度が高いため先鋭形状物質の引掛りによる生地の裂けを防ぐことができる生地として活用できる。さらに、フィルター材としては透過させる物質量を任意に変更できる利点を有する。 Examples of suitable industrial textile products of the high-density fabric of the present invention include protective clothing, safety protective equipment, filter materials and the like. Protective clothing and safety protective equipment can prevent injuries caused by piercing and suppress stuffiness when worn in environments where sharp-shaped substances such as barbed plants, bee needles, and blades can exist around you Since the tear strength is high, it can be used as a fabric that can prevent the fabric from tearing due to the catch of a sharp-shaped material. Further, the filter material has an advantage that the amount of substance to be transmitted can be arbitrarily changed.
