Description

編地knitted fabric
　本発明は、編地に関する。 The present invention relates to knitted fabrics.
　表裏二枚の地組織を弾性繊維で接結する編地は、快適な衣料を構成する生地として、アウター衣料、インナー衣料、スポーツ衣料を中心に需要が高まっている。 Knitted fabrics, in which two fabrics, front and back, are joined with elastic fibers, are in increasing demand as fabrics for comfortable clothing, especially for outerwear, innerwear, and sports clothing.
　例えば、以下の特許文献１では、表裏二枚の地組織がタック組織のみの接結糸で結合された立体弾性丸編地であって、該表裏二枚の地組織が非弾性繊維のみで構成され、該接結糸が弾性繊維のみで構成され、該弾性繊維が５～１５コース／１リピートで交編されており、該編地のループ密度が４０～１３０コース／インチ、３５～８０ウェル／インチであり、充填率が５．０～１５．０％以下であり、保温率が２０．０％以上であり、かつ、２．２５ｋｇ定荷重伸長率が、タテ方向で５０～２００％、ヨコ方向で１５０～３００％である立体弾性丸編地が開示されている。 For example, Patent Document 1 below discloses a three-dimensional elastic circular knitted fabric in which two ground weaves on the front and back sides are connected by a binding yarn having only a tuck weave, and the two ground weaves on the front and back sides are composed only of inelastic fibers. The binding yarn is composed only of elastic fibers, the elastic fibers are alternately knitted at 5 to 15 courses/1 repeat, and the loop density of the knitted fabric is 40 to 130 courses/inch, 35 to 80 wells. /inch, the filling rate is 5.0 to 15.0% or less, the heat retention rate is 20.0% or more, and the elongation rate at a constant load of 2.25 kg is 50 to 200% in the vertical direction. A circular knitted fabric with three-dimensional elasticity of 150 to 300% in the weft direction is disclosed.
　また、以下の特許文献２では、表面と裏面の独立した二層の地編地を結合してなる多層構造を有する弾性編地であって、前記二層の地編地が１７～３０００デシテックスのポリウレタン系弾性繊維裸糸のみで結合されている弾性編地が開示されている。 Further, Patent Document 2 below describes an elastic knitted fabric having a multilayer structure formed by combining two independent layers of ground knitted fabric on the front and back sides, wherein the two layers of ground knitted fabric have a density of 17 to 3000 decitex. An elastic knitted fabric is disclosed that is bonded only with bare threads of polyurethane elastic fibers.

　しかし、特許文献１に記載された編地は、弾性繊維が５～１５コース／１リピートで交編しているため、地組織を構成する非弾性繊維のループの自由度が大きくなり、編地の厚みが比較的大きくなる。その結果、特許文献１に記載された編地において、特にインナー衣料やスポーツ衣料等の用途に求められる高い曲げ柔らかさを得ることは困難であった。 However, in the knitted fabric described in Patent Document 1, the elastic fibers are alternately knitted with 5 to 15 courses/1 repeat, so the degree of freedom of the loops of the inelastic fibers that make up the ground structure is increased, and the knitted fabric becomes relatively thick. As a result, in the knitted fabric described in Patent Document 1, it was difficult to obtain high bending softness, which is particularly required for uses such as inner clothing and sports clothing.
　また、特許文献２に記載された編地は、緻密で通気抵抗が大きいため、繊維同士の摩擦が比較的大きくなる。その結果、特許文献２に記載された編地において、特にインナー衣料やスポーツ衣料等の用途に求められる高い曲げ柔らかさを得ることは困難であった。 Furthermore, since the knitted fabric described in Patent Document 2 is dense and has high ventilation resistance, the friction between the fibers is relatively large. As a result, in the knitted fabric described in Patent Document 2, it has been difficult to obtain high bending softness, which is particularly required for uses such as inner clothing and sports clothing.
　上記した先行技術の問題点に鑑み、本発明が解決しようとする課題は、曲げ柔らかさに優れた編地を提供することである。 In view of the problems of the prior art described above, the problem to be solved by the present invention is to provide a knitted fabric with excellent bending softness.

　本実施形態の編地は、緯編地、及び経編地のいずれであってもよいが、好ましくは緯編地であり、また、好ましくはダブル丸編機によって製造される。 The knitted fabric of this embodiment may be either a weft knitted fabric or a warp knitted fabric, but is preferably a weft knitted fabric, and is preferably manufactured by a double circular knitting machine.
　本実施形態の編地は、表の地組織と、裏の地組織とを含む。表の地組織と、裏の地組織とは、非弾性繊維を含み、弾性繊維を含むこともできるが、非弾性繊維のみで構成されることが好ましい。本明細書中、「非弾性繊維」とは、最大伸度が１００％より小さい繊維を意味し、「弾性繊維」とは、最大伸度１００％以上の繊維を意味する。表の地組織と、裏の地組織とに含まれる非弾性繊維は、天然繊維、化学繊維等を用いることが可能であり、特に制限されるものではない。天然繊維としては、綿、麻、絹、羊毛等が挙げられる。また、化学繊維としては、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等のポリエステル繊維、ナイロン６やナイロン６６等のポリアミド繊維、レーヨンやキュプラ、リヨセル等の再生セルロース繊維等が挙げられる。これらのブライト糸、セミダル糸、フルダル糸等任意に選択でき、繊維の断面形状も丸型、楕円型、Ｗ型、繭型、中空糸等任意な断面形状であってもよい。繊維形態についても特に限定されず、原糸、仮撚等の捲縮糸であってもよいが、曲げ柔らかさの観点から原糸の方が好ましい。また、これらの非弾性繊維は、インターレースによる複合や合撚等、複合繊維の形態であってもよい。非弾性繊維の繊度は編地の曲げ柔らかさの観点から１５０ｄｔｅｘ以下が好ましい。 The knitted fabric of this embodiment includes a front ground structure and a back ground structure. The front texture and the back texture contain inelastic fibers and can also contain elastic fibers, but are preferably composed of only inelastic fibers. In this specification, "inelastic fiber" means a fiber whose maximum elongation is less than 100%, and "elastic fiber" means a fiber whose maximum elongation is 100% or more. The inelastic fibers included in the front texture and the back texture can be natural fibers, chemical fibers, etc., and are not particularly limited. Examples of natural fibers include cotton, linen, silk, wool, and the like. Examples of chemical fibers include polyester fibers such as polyethylene terephthalate and polytrimethylene terephthalate, polyamide fibers such as nylon 6 and nylon 66, and regenerated cellulose fibers such as rayon, cupro, and lyocell. These bright yarns, semi-dull yarns, full dull yarns, etc. can be arbitrarily selected, and the fibers may have any cross-sectional shape such as round, oval, W-shape, cocoon-shape, hollow fiber, etc. The fiber form is not particularly limited either, and may be raw yarn or crimped yarn such as false twist, but raw yarn is preferable from the viewpoint of bending softness. Further, these inelastic fibers may be in the form of composite fibers such as interlaced composite fibers or pliable fibers. The fineness of the inelastic fibers is preferably 150 dtex or less from the viewpoint of bending softness of the knitted fabric.
　本実施形態の編地は、表の地組織と裏の地組織と連結する接結糸を含む。接結糸は弾性繊維を含み、非弾性繊維を含むカバリング糸等の複合糸であることもできるが、弾性繊維のみで構成されることが好ましい。接結糸に含まれる弾性繊維の組成、及び製造方法は、特に制限されるものはなく、ポリウレタン系又はポリエステル系の弾性繊維であることができ、公知の紡糸方法により製造される。例えば、ポリウレタン系弾性繊維としては、溶融紡糸、乾式紡糸、又は湿式紡糸により製造されたものが使用できる。弾性繊維は、染色加工時のファイナルセット工程の通常処理温度が１４０～１７０℃近辺で伸縮性が損なわないものであることが好ましい。また、弾性繊維としては、特殊ポリマーや粉体添加により、高セット性、抗菌性、吸湿、吸水などの機能性を付与したものも使用可能である。弾性繊維の繊度は編地の曲げ柔らかさの観点から５０ｄｔｅｘ以下が好ましく、より好ましくは１７～４４ｄｔｅｘである。 The knitted fabric of this embodiment includes binding yarns that connect the front ground weave and the back ground weave. Although the binding yarn may be a composite yarn such as a covering yarn containing elastic fibers and inelastic fibers, it is preferably composed of only elastic fibers. The composition and manufacturing method of the elastic fibers contained in the binding yarn are not particularly limited, and they may be polyurethane-based or polyester-based elastic fibers, and are manufactured by a known spinning method. For example, polyurethane elastic fibers manufactured by melt spinning, dry spinning, or wet spinning can be used. The elastic fiber is preferably one that does not lose its elasticity when the normal treatment temperature in the final setting step during dyeing is around 140 to 170°C. Further, as the elastic fiber, it is also possible to use a material that has been given functionality such as high setting property, antibacterial property, moisture absorption, and water absorption by adding a special polymer or powder. The fineness of the elastic fiber is preferably 50 dtex or less, more preferably 17 to 44 dtex, from the viewpoint of bending softness of the knitted fabric.
　本実施形態の編地は、以下の式：
　　　接結糸の編密度＝（１完全組織中の接結糸が編み込まれているコース数）／（１完全組織中の全コース数）
で定義される接結糸の編密度が１／３以上である。ここで、１完全組織とは、編地を構成する編組織の最小繰り返し単位を示す。例えば、図１の組織図の場合、１完全組織中の全コース数は２コース、１完全組織中の接結糸が編み込まれているコース数は２コースであるため、接結糸の編密度は１／１であり、図２の編組織図の場合、１完全組織中の全コース数は８コース、１完全組織中の接結糸が編み込まれているコース数は２コースであるため、接結糸の編密度は１／４である。接結糸の編密度が１／３以上であることで、接結糸によって、表裏二枚の地組織を構成する非弾性繊維のループの自由度が小さくなるため、編地の厚みが小さくなり、編地が曲げ柔らかくなる効果を発揮することができる。接結糸の編密度は、編地の曲げ柔らかさの観点から、１／２以上が好ましく、１／１が最も好ましい。接結糸の編密度１／１は、接結糸が全てのコースに含まれている状態である。 The knitted fabric of this embodiment has the following formula:
Knitting density of binding yarn = (number of courses in which binding yarn is woven in one complete tissue) / (total number of courses in one complete tissue)
The knitting density of the binding yarn defined by is 1/3 or more. Here, one complete structure indicates the minimum repeating unit of the knitted structure constituting the knitted fabric. For example, in the case of the organization chart in Figure 1, the total number of courses in one complete tissue is 2, and the number of courses in which the binding yarn is woven in one complete organization is 2, so the knitting density of the binding yarn is is 1/1, and in the case of the knitting organization diagram in Figure 2, the total number of courses in one complete organization is 8 courses, and the number of courses in which the binding yarn is knitted in one complete organization is 2 courses, so The knitting density of the binding yarn is 1/4. When the knitting density of the binding yarn is 1/3 or more, the degree of freedom of the loops of the inelastic fibers that make up the two fabrics on the front and back sides is reduced by the binding yarn, so the thickness of the knitted fabric becomes smaller. , the knitted fabric can exhibit the effect of bending and becoming softer. The knitting density of the binding yarn is preferably 1/2 or more, most preferably 1/1, from the viewpoint of bending softness of the knitted fabric. A knitting density of the binding yarn of 1/1 is a state in which the binding yarn is included in all courses.
　本実施形態の編地は、ＪＩＳ－Ｌ１０９６－Ａ法（フラジール法）による通気度が７０ｃｍ３／ｃｍ２・ｓ以上であり、好ましくは１００ｃｍ３／ｃｍ２・ｓ以上、より好ましくは１２０ｃｍ３／ｃｍ２・ｓ以上である。通気度が７０ｃｍ３／ｃｍ２・ｓ以上であると、編地は適度に疎な構造となるため、繊維同士の摩擦が減り、編地は曲げ柔らかくなる。通気度を７０ｃｍ３／ｃｍ２・ｓ以上とするためには、表の地組織と裏の地組織が非弾性繊維のみで構成されていること、接結糸が弾性繊維のみで構成されていること、接結糸が表の地組織と裏の地組織とをタック組織のみで接結すること、連結糸に含まれる弾性繊維の繊度が５０ｄｔｅｘ以下であること、又は、表の地組織と裏の地組織とに含まれる非弾性繊維の繊度が１５０ｄｔｅｘ以下であること等、繊維同士の摩擦が増えないように編地を設計することが好ましい。 The knitted fabric of this embodiment has an air permeability of 70 cm 3 /cm 2 ·s or more, preferably 100 cm 3 /cm 2 ·s or more, more preferably 120 cm 3 /cm 2 ·s or more, according to the JIS-L1096-A method (Fragir method). cm2・s or more. When the air permeability is 70 cm 3 /cm 2 ·s or more, the knitted fabric has a moderately sparse structure, which reduces friction between fibers and makes the knitted fabric bendable and soft. In order to achieve an air permeability of 70 cm 3 /cm 2 ·s or more, the front fabric and back fabric should be made of only inelastic fibers, and the binding yarn should be made of only elastic fibers. The binding yarn must connect the front fabric and the back fabric using only a tuck weave, the fineness of the elastic fibers contained in the connecting yarn must be 50 dtex or less, or It is preferable to design the knitted fabric so that the friction between the fibers does not increase, such as by setting the fineness of the inelastic fibers contained in the base structure to 150 dtex or less.
　本実施形態の編地は、接結糸を含むコースの厚みが１．００ｍｍ以下であることが好ましい。編地の前記厚みが１．００ｍｍ以下であれば、編地が曲げ柔らかくなる。 In the knitted fabric of this embodiment, it is preferable that the thickness of the course containing the binding yarn is 1.00 mm or less. If the thickness of the knitted fabric is 1.00 mm or less, the knitted fabric becomes bendable and soft.
　本実施形態の編地は、表の地組織又は裏の地組織に含まれる非弾性繊維の質量に対する、接結糸に含まれる弾性繊維の質量の比の値が０．０２～０．４０であることが好ましく、０．０２～０．２４であることがより好ましく、０．０２～０．１６であることがさらに好ましい。前記比の値が０．１６以下であると、接結糸に含まれる弾性繊維の伸縮性によって表の地組織及び裏の地組織が接近し厚みが小さくなるため、編地が曲げ柔らかくなる。前記比の値が０．０２以上であると、接結糸に含まれる弾性繊維が非弾性繊維の質量に十分に耐えて糸切れしにくい。前記の比の値を０．０２～０．１６とするためには、表の地組織又は裏の地組織に含まれる非弾性繊維の繊度に対する、接結糸に含まれる弾性繊維の繊度の比の値が０．１２～０．７８であること、又は、表の地組織又は裏の地組織に含まれる非弾性繊維の長さに対する接結糸に含まれる弾性繊維の長さの比が０．３５以下であることが好ましい。 In the knitted fabric of this embodiment, the ratio of the mass of the elastic fibers contained in the binding yarn to the mass of the inelastic fibers contained in the front fabric or the back fabric is 0.02 to 0.40. It is preferably from 0.02 to 0.24, even more preferably from 0.02 to 0.16. When the value of the ratio is 0.16 or less, the front ground texture and the back ground texture become close to each other due to the elasticity of the elastic fibers contained in the binding yarn, resulting in a decrease in thickness, making the knitted fabric bendable and soft. When the value of the ratio is 0.02 or more, the elastic fibers contained in the binding yarn can sufficiently withstand the mass of the inelastic fibers, making it difficult for the yarn to break. In order to set the value of the ratio to 0.02 to 0.16, the ratio of the fineness of the elastic fibers contained in the binding yarn to the fineness of the inelastic fibers contained in the front fabric or the back fabric. The value of is 0.12 to 0.78, or the ratio of the length of elastic fibers included in the binding yarn to the length of inelastic fibers included in the front fabric or back fabric is 0. It is preferable that it is .35 or less.

Measurement was performed according to the JIS-L1096-A method (Fragir method) to determine the amount of air passing through the test piece per unit area and unit time.
（３）編地の厚み（ｍｍ）
　接結糸を含むコースにおいて編地を緯方向に裁断し、観察サンプルを作製した。無緊張状態の前記観察サンプルを平台に両面テープで貼り付け、固定した。その後マイクロスコープ（キーエンス社製ＶＨＸ－６０００）を用いて、接結糸を含むコースの断面を編み終わり側から撮影した。撮影した画像において、図３のように、表の地組織の頂点が接する直線と裏の地組織の頂点が接する直線が平行になるよう２本の直線を描いた。これら２本の直線間の距離を編地の厚みとした。 (3) Thickness of knitted fabric (mm)
The knitted fabric was cut in the weft direction in the course containing the binding yarn to prepare observation samples. The observation sample in a stress-free state was attached and fixed on a flat stand with double-sided tape. Thereafter, using a microscope (VHX-6000 manufactured by Keyence Corporation), a cross section of the course including the binding yarn was photographed from the knitting end side. In the photographed image, two straight lines were drawn so that the line where the apex of the front ground texture touches and the line where the apex of the back ground texture touch are parallel, as shown in Figure 3. The distance between these two straight lines was defined as the thickness of the knitted fabric.
（４）編地の曲げ剛性（ｃＮ・ｃｍ２／ｃｍ）

　曲げ剛性は、値が小さいほど、編地が柔らかさに優れる。本実施例においては、曲げ剛性が０．０１８０ｃＮ・ｃｍ２／ｃｍ以下であれば曲げ柔らかいと判断し、さらに０．０１００ｃＮ・ｃｍ２／ｃｍ以下であれば、曲げ柔らかさに優れると判断した。 (4) Bending rigidity of knitted fabric (cN・cm 2 /cm)
Measurement is performed using a KES-FE2-AUTO-A automatic pure bending tester manufactured by Kato Tech Co., Ltd. A knitted fabric cut to a width of 20.0 cm and a length of 20.0 cm is used as a test piece. Place the test piece on the sample stand so that the cut part in the warp direction of the knitted fabric is at the back of the sample stand, insert the test piece to the back until the sample insertion position confirmation lamp lights up, and check the bending stiffness in the weft direction of the knitted fabric (editing). Measure the hardness of the knitted fabric when it is folded to create a crease in the warp direction. In this example, the measurement sensitivity was set to 4.0 gf·cm/10V, but it may be adjusted as appropriate in the range of 4.0 to 50.0 gf·cm/10V depending on the bending rigidity of the test piece. It's okay. In the testing machine, the bending stiffness when the knitted fabric is bent upward and the bending stiffness when bent downward are measured, and the average value thereof is used. The test is conducted on three test pieces and the average thereof is calculated. Incidentally, since the unit of the test machine is output as gf·cm 2 /cm, this is multiplied by 0.980665 to convert into cN·cm 2 /cm.
As for the bending rigidity, the smaller the value, the more excellent the softness of the knitted fabric. In this example, if the bending rigidity was 0.0180 cN·cm 2 /cm or less, it was determined that the material was bending soft, and if it was 0.0100 cN·cm 2 /cm or less, it was determined that it was excellent in bending softness.
