Description

織物及び衣類Textiles and clothing
　本発明は織物に関する。詳しくは、軽量であり、十分な強度を有する、伸縮性の高い織物、及びこの織物からなる衣類に関するものである。 The present invention relates to a fabric. Specifically, the present invention relates to a highly stretchable fabric that is lightweight and has sufficient strength, and a garment made of the fabric.
　近年、特にスポーツ用途において伸縮性の高い織物（以下、高伸度織物とする）が伸縮性の高い編物に替わって使用されてきている。織物は編物に比べ素材を軽量化できることが一つの利点である。しかし、高伸度織物をスポーツ用途に使用した場合、破裂強度や引裂強度が十分ではなく、着用時に破損することがあるため、織物をこのような分野に商品展開するには限度があった。 In recent years, fabrics with high elasticity (hereinafter referred to as high elongation fabrics) have been used in place of highly knitted fabrics, particularly in sports applications. One advantage of woven fabrics is that they can reduce the weight of materials compared to knitted fabrics. However, when a high elongation fabric is used for sports applications, the burst strength and tear strength are not sufficient, and the fabric may be damaged when worn, so there is a limit to commercializing the fabric in such a field.
　従来知られている織物の強度を向上させる方法として、例えば織物を構成している糸を太くすることが挙げられるが、この場合、目付が高くなるので編物の替わりに織物を使用するメリットが得られなくなってしまう。目付を低くするために織密度を減少させると、強度が低下するうえに滑脱抵抗力が低下してしまう。織物の強度を向上させる他の方法として織密度を高くする方法があるが、この場合、高い伸縮性が得られなくなり、また、目付も高くなってしまう。 As a conventionally known method for improving the strength of a woven fabric, for example, thickening the yarn constituting the woven fabric can be mentioned. In this case, since the basis weight is increased, the merit of using the woven fabric instead of the knitted fabric is obtained. It will not be possible. When the weave density is decreased to reduce the basis weight, the strength is lowered and the slip resistance is also decreased. As another method for improving the strength of the woven fabric, there is a method of increasing the weave density. In this case, high stretchability cannot be obtained, and the basis weight is also increased.
　高伸度織物に関しては、例えば特許文献１には、ポリウレタンを芯部に持つコンジュゲート糸を使用する方法が開示されている。しかしコンジュゲート糸は強度に欠け、大きな伸縮性を得られにくいため、経方向、緯方向共に伸度が４０％以上の織物を得ることが困難である。また、溶融紡糸のためポリウレタンの融点が低く、特許文献１に記載の織物を使用して衣類を製造する場合において、高温の熱をかけるとポリウレタンが溶け出すおそれがある。そのため、転写プリントや熱転写シート、融着テープ等の使用が困難であるなど、実用上の制約が大きく現実的ではない。 Regarding high elongation fabrics, for example, Patent Document 1 discloses a method of using a conjugate yarn having polyurethane as a core. However, since the conjugate yarn lacks strength and it is difficult to obtain great stretchability, it is difficult to obtain a woven fabric having an elongation of 40% or more in both the warp direction and the weft direction. In addition, since the melting point of polyurethane is low due to melt spinning, when manufacturing a garment using the woven fabric described in Patent Document 1, there is a risk that the polyurethane melts when high temperature heat is applied. Therefore, practical restrictions are large and unrealistic, such as difficulty in using transfer prints, thermal transfer sheets, and fusion tapes.
　また、特許文献２には、仮撚り加工糸からなる織物に高融点ワックス配合の収束平滑剤を付与することにより織物のストレッチ性を向上させる方法が開示されているが、この方法では、軽量ではあるが、強度は十分ではなく、製織時の織密度が低い上に、仕上げ加工時に高融点ワックスを付与するために、経糸や緯糸同士の間隔が部分的に広くなったり、逆に狭くなったりする欠点があり、いわゆる目ずれの問題がある。上記のように、軽量であり、十分な強度を有する、伸縮性の高い織物は未だ得られていない。 Patent Document 2 discloses a method for improving the stretchability of a woven fabric by adding a convergence smoothing agent containing a high melting point wax to a woven fabric made of false twisted yarn. However, the strength is not enough, the weaving density is low at the time of weaving, and in order to give a high melting point wax at the time of finishing processing, the spacing between the warp and weft is partially widened or conversely narrowed There is a drawback of so-called misalignment. As described above, a highly stretchable fabric that is lightweight and has sufficient strength has not yet been obtained.

　以下、本発明の実施の形態について詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail.
　本発明の織物は、経糸および緯糸として、芯糸と鞘糸を組み合わせてなる糸条、特には後述するように特定の弾性糸を芯糸にして特定の合成繊維からなる鞘糸をカバーリングすることによって得られた芯鞘複合構造の糸条（芯鞘複合糸又はカバーリング糸と称する）を用いて製された織物である。 The woven fabric of the present invention covers as a warp and weft a yarn formed by combining a core yarn and a sheath yarn, and in particular covers a sheath yarn made of a specific synthetic fiber using a specific elastic yarn as a core yarn as described later. This is a woven fabric made by using a yarn having a core-sheath composite structure (referred to as a core-sheath composite yarn or a covering yarn).
　芯糸に鞘糸をカバーリングして組み合わせる方法は、芯糸に鞘糸を巻きつけるカバーリング、エア交絡つまりエア噴射を利用して鞘糸を芯糸に交絡させて巻きつけるエアカバーリング（エア交絡カバーリング）のいずれのカバーリング方法を用いたものでもよい。芯糸に鞘糸をカバーリングして組み合わせる際の芯糸のドラフト率（鞘糸を巻きつける際の芯糸の伸び率）は、織物の使用目的に応じて任意のドラフト率を適宜採用すればよく、一般的にはドラフト率は２．０～４．０である。芯糸に鞘糸を巻きつける際の撚回数は、商品の目的に応じて任意の撚回数を使用すればよく、一般的には撚回数は６００～２０００Ｔ／ｍである。 Covering the core yarn by covering the sheath yarn with the core yarn is a covering that wraps the sheath yarn around the core yarn, air entanglement, that is, air covering that wraps the sheath yarn around the core yarn using air injection (air Any covering method of entanglement covering) may be used. The draft rate of the core yarn when covering and combining the sheath yarn with the core yarn (elongation rate of the core yarn when winding the sheath yarn) can be appropriately selected according to the intended use of the fabric. In general, the draft rate is generally 2.0 to 4.0. The number of twists in winding the sheath yarn around the core yarn may be any number of twists depending on the purpose of the product, and the number of twists is generally 600 to 2000 T / m.
　通常の巻きつけによるカバーリングの好適な加工条件は、下記の通りである。

　　　　　　撚回数　　５００～１６００Ｔ／ｍ Suitable processing conditions for the cover ring by normal winding are as follows.

　　　　　　噴射エア圧　　　　３～８ｋｇ
　　　　　　撚回数　　　　　　６００～２０００Ｔ／ｍ The preferred processing conditions for air covering are as follows.
Processing conditions Core yarn draft ratio 2.0-4.0

　高い伸度を得るため、織物を構成する糸条にコンジュゲート糸やポリトリメチレンテレフタレート繊維、ポリブチレンテレフタレート繊維を使用した糸条（芯鞘複合糸ではないもの）等を用いる方法も考えられるが、前述のいずれの糸条を用いても経方向および緯方向ともに４０％以上の伸度を得ることは困難である。また、コンジュゲート糸は一般的に薄地にした場合に十分な強度を得にくいという問題がある。 In order to obtain high elongation, it is possible to use a yarn (not a core-sheath composite yarn) using a conjugate yarn, a polytrimethylene terephthalate fiber, or a polybutylene terephthalate fiber as a yarn constituting the woven fabric. Even if any of the above-described yarns is used, it is difficult to obtain an elongation of 40% or more in both the warp direction and the weft direction. Further, the conjugate yarn generally has a problem that it is difficult to obtain sufficient strength when it is made thin.
　これに対し、特定の弾性糸を芯糸にして特定の合成繊維の鞘糸をカバーリンして組み合わせることによって得られる芯鞘複合構造の糸条を用いることで、経方向および緯方向ともに４０％以上の伸度が得られる上、十分な強度を有する織物を得ることができる。一般に、身体の屈曲による皮膚表面の伸度は約６０％であることから、本発明の織物からなる衣服を着用した場合の着用感を良好にし、かつ着用により適度な緊締力を得るためには、該織物の伸度は４０％以上であることが好ましい。生地の伸度が４０％未満の場合、屈曲時に大きな力が必要となり、身体の自由な運動を阻害するおそれがある。 On the other hand, by using a core-sheath composite yarn obtained by combining a specific elastic yarn as a core yarn and covering and combining a sheath yarn of a specific synthetic fiber, both warp and weft directions are 40%. In addition to the above elongation, a woven fabric having sufficient strength can be obtained. In general, since the elongation of the skin surface due to bending of the body is about 60%, in order to improve the feeling of wearing when the clothes made of the fabric of the present invention are worn and to obtain an appropriate tightening force by wearing, The elongation of the woven fabric is preferably 40% or more. If the elongation of the fabric is less than 40%, a large force is required at the time of bending, which may hinder free movement of the body.
　前記の糸条において、芯糸に使用する繊維は、弾性糸であること、特には染色加工時に十分収縮することのできるポリウレタン繊維であることが求められる。鞘糸に使用する合成繊維については、様々な繊維が使用可能であるが、例えば、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などのポリエステル繊維やナイロン６６、ナイロン６などのポリアミド繊維等の合成繊維、アセテート、トリ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挙げることができ、これらが２種以上組み合わされていてもよい。なかでも、強度面・染色堅牢度面を考慮するとカチオン可染ポリエステルかナイロンが好ましく、強度に優れることからナイロン６６またはナイロン６が特に好ましい。 In the above-described yarn, the fiber used for the core yarn is required to be an elastic yarn, particularly a polyurethane fiber that can be sufficiently contracted during dyeing. Various fibers can be used for the synthetic fiber used for the sheath yarn. For example, synthetic fibers such as polyester fibers such as polyethylene terephthalate and polytrimethylene terephthalate, polyamide fibers such as nylon 66 and nylon 6, acetate, Examples thereof include semisynthetic fibers such as triacetate, and regenerated fibers such as rayon and cupra, and two or more of these may be combined. Of these, cationic dyeable polyester or nylon is preferable in view of strength and dyeing fastness, and nylon 66 or nylon 6 is particularly preferable because of excellent strength.
　本発明の織物を構成する糸条の芯糸の形態は、フィラメント糸であるればよく、モノフィラメント糸であっても、マルチフィラメント糸であってもよい。また、鞘糸の形態は、特に限定されるものではなく、フィラメント糸または紡績糸のいずれであってもよい。フィラメント糸の場合は、生糸、仮撚加工糸、撚糸などのいずれでもよく、またこれらの、混紡、混繊等の手段によって得られる複合糸であってもよい。さらに、鞘糸の単繊維の断面形状についても特に限定されず、丸、三角など公知の断面形状が採用でき、中空部を有するものであってもよい。 The form of the core yarn of the yarn constituting the woven fabric of the present invention may be a filament yarn, and may be a monofilament yarn or a multifilament yarn. The form of the sheath yarn is not particularly limited, and may be either a filament yarn or a spun yarn. In the case of filament yarn, any of raw yarn, false twisted yarn, twisted yarn, etc. may be used, and composite yarn obtained by means of these blends, blends, etc. may be used. Furthermore, the cross-sectional shape of the single fiber of the sheath yarn is not particularly limited, and a known cross-sectional shape such as a circle or a triangle can be adopted, and a hollow portion may be used.
　本発明の織物を構成する糸条の繊度として、芯糸の繊度は７８ｄｔｅｘ以下であることが求められ、また、鞘糸の繊度は４４ｄｔｅｘ以下であることが求められる。すなわち、前記の繊度を超える繊度の糸を用いた場合、軽量な織物を得ることができないおそれがある。前記芯糸および鞘糸の繊度が小さくなると、十分な強度を得られなくなるおそれがあるので、実施上は、芯糸は繊度２２ｄｔｅｘ以上、すなわち２２～７８ｄｔｅｘの糸が用いられ、鞘糸は繊度１０ｄｔｅｘ以上、すなわち１０～４４ｄｔｅｘ、好ましくは１５～４０ｄｔｅｘの糸、さらに好ましくは２０～３５ｄｔｅｘの糸が用いられる。いずれにしても、前記糸条の総繊度は、使用上の強度確保の点から３０ｄｔｅｘ以上のものとするのが好ましい。 As the fineness of the yarn constituting the fabric of the present invention, the fineness of the core yarn is required to be 78 dtex or less, and the fineness of the sheath yarn is required to be 44 dtex or less. That is, when a yarn having a fineness exceeding the fineness is used, there is a possibility that a lightweight fabric cannot be obtained. If the fineness of the core yarn and sheath yarn is reduced, sufficient strength may not be obtained. Therefore, in practice, a yarn having a fineness of 22 dtex or more, that is, 22 to 78 dtex is used as the core yarn, and the fineness of sheath yarn is 10 dtex. More specifically, a yarn of 10 to 44 dtex, preferably 15 to 40 dtex, more preferably 20 to 35 dtex is used. In any case, the total fineness of the yarn is preferably 30 dtex or more from the viewpoint of securing strength in use.
　本発明の織物は、上記の糸条を後述する組織で製織した織物を、精練、染色等の染色加工工程を経て得られる。 The woven fabric of the present invention is obtained through a dyeing process such as scouring and dyeing a woven fabric obtained by weaving the above-described yarn with a structure described later.
　本発明の織物のカバーファクター（ＣＦ）は２５００～５０００であることが好ましく、２５００～４０００であることが更に好ましい。カバーファクターが２５００未満であると、破裂強度を３３０ｋＰａ以上確保することが難しくなる。カバーファクターが５０００を超えると重くなって、目付が１８０ｇ／ｍ２を超えるおそれがあり、また、伸度を４０％以上確保することが難しくなる。 The cover factor (CF) of the fabric of the present invention is preferably 2500 to 5000, and more preferably 2500 to 4000. If the cover factor is less than 2500, it is difficult to ensure a burst strength of 330 kPa or more. If the cover factor exceeds 5000, the cover factor becomes heavy, the basis weight may exceed 180 g / m 2, and it becomes difficult to secure an elongation of 40% or more.
　本発明における織物のカバーファクターは下記式によって算出される。  
　　ＣＦ＝Ｄ１１／２×Ｍ１＋Ｄ２１／２×Ｍ２
　　　Ｄ１：経糸の総繊度（ｄｔｅｘ）
　　　Ｄ２：緯糸の総繊度（ｄｔｅｘ）
　　　Ｍ１：経糸の密度（本／２．５４ｃｍ）
　　　Ｍ２：緯糸の密度（本／２．５４ｃｍ） The cover factor of the fabric in the present invention is calculated by the following formula.
CF = D1 1/2 × M1 + D2 1/2 × M2
D1: Total fineness of warp (dtex)
D2: Total fineness of weft (dtex)
M1: Density of warp (main / 2.54cm)
M2: Weft density (main / 2.54cm)
　また、本発明の織物の、経糸および緯糸の総繊度Ｄ（Ｄ１およびＤ２）は下記式によって算出される。  
　　Ｄ＝Ｄｃ／Ｄｆ＋Ｄｓ
　　　Ｄｃ：芯糸の繊度
　　　Ｄｓ：鞘糸の繊度
　　　Ｄｆ：ドラフト率 Moreover, the total fineness D (D1 and D2) of the warp and the weft of the fabric of the present invention is calculated by the following formula.
D = Dc / Df + Ds
Dc: Fineness of core yarn Ds: Fineness of sheath yarn Df: Draft rate
　本発明の織物の組織は、経糸および緯糸の少なくとも一方の糸、好ましくは双方の糸の他方の糸に対する浮き本数（完全組織内の最大の浮き本数）が２～６本となる織組織、言い換えると、経糸と緯糸の交錯点の飛び数が２～６本の織組織であることが求められる。すなわち、平織では片マット組織やマット組織など、綾織、朱子織などが求められる。綾織では２／１綾、２／２綾、３／１綾など、朱子織では破れ朱子、５枚朱子、７枚朱子などのような、交錯点の少ない組織であることが好ましい。また、少なくとも一方の糸の浮き本数が２～６本となる組織であれば、これらの組織を組み合わせた変化組織であっても構わない。 The structure of the woven fabric of the present invention is a woven structure in which the number of floats (the maximum number of floats in the complete structure) of at least one of warp and weft yarns, preferably the other yarns of the two yarns, is 2 to 6, in other words Therefore, it is required that the number of jumps at the intersection of the warp and the weft is 2 to 6 woven structures. That is, in the plain weave, a single mat structure or a mat structure such as a twill weave or satin weave is required. It is preferable to have a structure with few crossing points, such as 2/1 twill, 2/2 twill, 3/1 twill, etc. Further, as long as at least one of the yarns has a number of floats of 2 to 6, a changed structure obtained by combining these structures may be used.
　伸縮性布帛において、高い伸度を得るためには染色加工工程中に大きく収縮させておくことが重要である。つまり、本発明の織物を構成する糸条（芯鞘複合糸）を染色加工工程中に収縮させる、すなわち織物全体を収縮させておくことで、その収縮した分だけ、染色加工後の織物が伸縮するのである。高い強度を得るためにカバーファクターを増大させると、タフタ組織のように、経糸および緯糸の少なくとも一方の糸の浮き本数が１本の組織である場合、経糸と緯糸の交錯点が多い組織であるため、経糸および緯糸の少なくとも一方の糸の浮き本数が２～６本となる組織に比べて染色加工工程中での収縮率が小さくなる。染色加工工程中での収縮率が小さいと、伸度を４０％以上確保することが難しくなる。また、経糸および緯糸の少なくとも一方の糸の浮き本数が７本以上である場合は、カバーファクターを増大させても十分な伸度が得られるが、組織表面に浮き出る糸長が長くなるために織物の耐摩耗性が低下したり、染色加工後に布帛がカーリングを起こし、縫製が困難になったりするおそれがある。 In order to obtain a high degree of elongation in a stretchable fabric, it is important that the fabric is greatly shrunk during the dyeing process. In other words, the yarn (core-sheath composite yarn) constituting the fabric of the present invention is contracted during the dyeing process, that is, the entire fabric is contracted, so that the fabric after the dyeing process is expanded and contracted by the contracted amount. To do. When the cover factor is increased in order to obtain high strength, when the number of floats of at least one of the warp and the weft is one structure, such as a taffeta structure, the structure has many intersections of the warp and the weft. Therefore, the shrinkage rate during the dyeing process is smaller than in a structure in which the number of floats of at least one of the warp and the weft is 2-6. If the shrinkage rate during the dyeing process is small, it is difficult to ensure an elongation of 40% or more. Further, when the number of floats of at least one of the warp and weft is 7 or more, sufficient elongation can be obtained even if the cover factor is increased. There is a risk that the wear resistance of the fabric may be reduced, or that the fabric may curl after dyeing, making sewing difficult.
　本発明の織物の目付は１００～１８０ｇ／ｍ２であることが好ましい。目付が１００ｇ／ｍ２未満であると、スポーツ衣料の実用に耐える織物を得るのが難しくなり、１８０ｇ／ｍ２を超えると本発明の目的である軽量な織物を得られなくなる。 The basis weight of the fabric of the present invention is preferably 100 to 180 g / m 2 . If the basis weight is less than 100 g / m 2 , it will be difficult to obtain a fabric that can withstand practical use of sports clothing, and if it exceeds 180 g / m 2 , the lightweight fabric that is the object of the present invention cannot be obtained.
　本発明の織物の特徴は、軽量でありながら、強度が高いことにある。織物がスポーツ衣料の実用に耐えるために引裂き強度は１０Ｎ以上、破裂強度が３３０ｋＰａ以上であることが好ましい。本発明は、織物の組織と、織物を構成する糸の繊度と密度、すなわち、カバーファクターを上記の範囲にすることにより、軽量であって十分な強度を有する、高伸度織物が得られるのである。 The feature of the fabric of the present invention is that it is lightweight but has high strength. It is preferable that the tear strength is 10 N or more and the burst strength is 330 kPa or more so that the fabric can withstand practical use of sports clothing. In the present invention, a high-strength fabric having a light weight and sufficient strength can be obtained by setting the fabric structure and the fineness and density of the yarn constituting the fabric, that is, the cover factor, within the above range. is there.
　また、本発明の織物の滑脱抵抗力は４ｍｍ以下であることが好ましい。滑脱抵抗力が４ｍｍを超えると、織物がスポーツ衣料の実用に耐えることができなくなる。 Moreover, it is preferable that the sliding resistance of the fabric of the present invention is 4 mm or less. If the sliding resistance exceeds 4 mm, the fabric cannot withstand the practical use of sports clothing.
　また、本発明の織物には、本発明の目的が損なわれない範囲内であれば、通常の染色仕上げ加工だけでなく、アルカリ減量加工、吸水加工、撥水加工、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。 In addition, in the woven fabric of the present invention, as long as the purpose of the present invention is not impaired, not only ordinary dyeing finishing processing, but also alkali weight reduction processing, water absorption processing, water repellent processing, ultraviolet shielding or antistatic agent, Various processes that provide functions such as antibacterial agents, deodorants, insect repellents, phosphorescent agents, retroreflective agents, and negative ion generators may be additionally applied.
　さらに、本発明の織物には、必要により各種の後加工を施して付加価値を高めることができる。たとえばプリント加工、加熱エンボス加工やパンチング加工によって所望の模様を施してもよい。さらに混紡、交織などの手段で第３の繊維を混用し、編成後に第３の繊維を薬品の捺染等によって部分的に除去し模様を出す、いわゆるオパール加工を施して、模様のある美しい織物にしてもよい。 Furthermore, the textile fabric of the present invention can be subjected to various post-processing as necessary to increase added value. For example, a desired pattern may be formed by printing, hot embossing, or punching. Furthermore, the third fibers are mixed by means of blending, interweaving, etc., and after the knitting, the third fibers are partially removed by chemical printing or the like to create a pattern. May be.
　本発明の織物は、軽量であり、十分な強度と優れた伸縮性を併せ有しているために、たとえば、水着、フィットネスウエア、レオタード、スパッツなどのスポーツ衣類、ガードル、ショーツ、ボディスーツ、シャツなどの肌着類などに好適に用いることができる。 The woven fabric of the present invention is lightweight, and has both sufficient strength and excellent stretchability. For example, sports clothing such as swimwear, fitness wear, leotards, spats, girdle, shorts, body suits, shirts It can be suitably used for underwear such as.
