Description
本発明は、ブラジャーカップ材や肩パット材などの保形材として用いることのできる、伸縮性に優れ、適度な布帛硬度、優れた洗濯耐久性を有すると共に通気性に優れた立体構造経編地に関する。 The present invention is a three-dimensional warp knitted fabric having excellent stretchability, moderate fabric hardness, excellent washing durability and excellent breathability that can be used as a shape-retaining material such as brassiere cup material and shoulder pad material. About.
従来、ブラジャーカップ用素材としてウレタンフォームや不織布と織物や編物等の基布とを積層構造にしたものを、縫製や成型等の方法により立体形状に加工して用いていた。
しかし、ウレタンフォームは保形性、反発性、耐洗濯性に優れているが通気性に乏しく、耐光性が悪く黄変するという問題がある。
また不織布は耐光性、通気性に優れているが、保形性、耐洗濯性が悪く、型くずれ、嵩の減少、毛羽の発生や不織布と基布が剥がれるなどの問題がある。
これらを解決するものとして、特許文献１にはバインダーで固められた不織布成型体のブラジャーカップが開示されているが、バインダーを使用しているため風合いをコントロールすることが難しく、また弾性も不十分で、押圧されて凹んだ場合の反発力はほとんどなく、バインダーの経時的物性変化などもあって好ましいとはいえない。
更に、これらの素材は織物や編物などと積層構造にしなければブラジャーカップ素材としては用いることができず、そのためのラミネート工程が必要であった。
Conventionally, as a material for a brassiere cup, a polyurethane foam or non-woven fabric and a base fabric such as a woven fabric or a knitted fabric are laminated and processed into a three-dimensional shape by a method such as sewing or molding.
However, urethane foam is excellent in shape retention, resilience and washing resistance, but has a problem of poor breathability, poor light resistance and yellowing.
In addition, the nonwoven fabric is excellent in light resistance and air permeability, but has poor shape retention and washing resistance, and there are problems such as loss of shape, reduction in bulk, generation of fluff and peeling of the nonwoven fabric and the base fabric.
As a solution to these problems, Patent Document 1 discloses a brassiere cup of a nonwoven fabric molded body hardened with a binder. However, since the binder is used, it is difficult to control the texture and the elasticity is insufficient. Thus, there is almost no repulsive force when pressed and recessed, and it is not preferable because of changes in physical properties of the binder over time.
Furthermore, these materials cannot be used as a brassiere cup material unless they are laminated with a woven fabric, a knitted fabric or the like, and a laminating process for that purpose is required.
また、最近では、ダブルラッセル素材単体を用いたブラジャーカップ素材も開発されている。しかし、立体形状に形成する場合に湾曲部にシワを生じたりする虞があった。また、重量が重く、風合いが硬く、また、通気性の悪いものが多かった。 Recently, a brass cup material using a single double raschel material has also been developed. However, there is a possibility that wrinkles are generated in the curved portion when the three-dimensional shape is formed. In addition, the weight was heavy, the texture was hard, and there were many things with poor air permeability.
本発明は上述の問題点を解決し、通気性があり、風合いが柔らかく、保形性が良好であって、素材単体でブラジャーカップとして用いることのできる、立体構造経編素材を提供するものである。 The present invention solves the above-described problems, and provides a three-dimensional warp knitted material that is breathable, soft in texture, has good shape retention, and can be used as a brassiere cup by itself. is there.

本発明は、上記の如く、表裏の地組織を連結糸で連結された繊維構造体において、布帛伸度が２０〜５０％、通気度が１５０ｃｃ／ｃｍ２・ｓ以上、布帛硬度が４０〜７０ｍｍであることを特徴とする立体構造経編地であって、通気性があって、風合いが柔らかく、保形性は良好であって、素材単体でブラジャーカップとして用いることのできる立体構造経編地を提供するものである。 As described above, the present invention is a fiber structure in which the front and back ground structures are connected by connecting yarns, the fabric elongation is 20 to 50%, the air permeability is 150 cc / cm 2 · s or more, and the fabric hardness is 40 to 70 mm. 3D structure warp knitted fabric characterized by being 3D structure warp knitted fabric that has air permeability, soft texture, good shape retention, and can be used as a bra cup by itself Is to provide.
本発明は、表裏の地組織と該地組織を連結する連結糸からなる繊維構造体であって、好ましくは２枚の針床を有する編機で製造され、ダブルラッセル編機、ダブルジャージー編機によって得られる３層構造編地のことをいうが、本発明の立体構造経編地は、ダブルラッセル編機を用いたものが好ましい。
また、本発明において、立体構造経編地を構成する繊維としては、ポリエチレンテレフタレート等のポリエステル系繊維、ナイロン等のポリアミド系繊維、セルロース系再生繊維、ポリアクリロニトリル繊維、木綿、絹、ウール等の天然繊維等、及びこれらの混繊繊維等が挙げられるが、加熱圧縮成型性、圧縮反発性、耐洗濯性、柔軟性等の点からポリエステル繊維を主体とする構成であることが好ましい。
The present invention is a fiber structure composed of a front and back ground structure and a connecting yarn that connects the ground structure, and is preferably manufactured by a knitting machine having two needle beds, a double raschel knitting machine, a double jersey knitting machine The three-dimensional structure warp knitted fabric of the present invention is preferably one using a double raschel knitting machine.
Further, in the present invention, the fibers constituting the three-dimensional warp knitted fabric include polyester fibers such as polyethylene terephthalate, polyamide fibers such as nylon, cellulose regenerated fibers, polyacrylonitrile fibers, cotton, silk, wool, and other natural fibers. Examples thereof include fibers and the like, mixed fibers thereof, and the like. From the viewpoint of heat compression moldability, compression resilience, washing resistance, flexibility, and the like, a configuration mainly composed of polyester fibers is preferable.
本発明は、表裏の地組織を連結糸で連結された繊維構造体において、特定の布帛伸度、通気度、布帛硬度を同時に有する、胸衣用に適した立体構造経編地素材を見いだしたものである。 The present invention has found a three-dimensional warp knitted fabric material suitable for breast apparel having a specific fabric elongation, air permeability, and fabric hardness at the same time in a fiber structure in which front and back ground structures are connected by connecting yarns. Is.
本発明は、表裏の地組織を連結糸で連結された立体構造経編地において、ＪＩＳ Ｌ １０９６ Ｂ−１法による布帛伸度が、タテ、ヨコ共２０〜５０％であることを必須とする立体構造経編地である。布帛伸度が２０％未満であると身体の形状に沿いにくくなり、５０％より大きくなると、保形性が悪くなる為乳房形状の補正力を発揮できない虞がある。 In the three-dimensional structure warp knitted fabric in which the front and back ground structures are connected by a connecting yarn, the present invention requires that the fabric elongation according to the JIS L 1096 B-1 method is 20 to 50% for both warp and width. It is a three-dimensional warp knitted fabric. If the fabric elongation is less than 20%, it becomes difficult to conform to the shape of the body, and if it exceeds 50%, the shape-retaining ability is deteriorated, so that there is a possibility that the breast shape correction force cannot be exhibited.
また、本発明の立体構造経編地は通気度が１５０ｃｃ／ｃｍ２・ｓ以上であることを必須とするものである。通気度が１５０ｃｃ／ｃｍ２・ｓ未満であると、胸衣用として用いた場合、蒸れを感じる虞があるので好ましくない。 The three-dimensional structure warp knitted fabric of the present invention is required to have an air permeability of 150 cc / cm 2 · s or more. If the air permeability is less than 150 cc / cm 2 · s, it is not preferable because it may cause stuffiness when used for breast clothing.
さらに、布帛硬度は４０〜７０ｍｍである。布帛硬度が４０ｍｍ未満であると風合いが硬くなる虞があり、７０ｍｍより大きくなると柔軟性が大きすぎて乳房形状補正力が十分得られない虞がある。また、本発明の布帛硬度とはＪＩＳ Ｌ １０１８ カンチレバー法にて測定したものである。 Furthermore, the fabric hardness is 40 to 70 mm. If the fabric hardness is less than 40 mm, the texture may be hard, and if it is greater than 70 mm, the flexibility may be too great to obtain a sufficient breast shape correction force. The fabric hardness of the present invention is measured by the JIS L 1018 cantilever method.
また、本発明で用いる連結糸は単糸繊度が３〜６ｄｔｅｘの糸で構成された繊度が３３〜１１０ｄｔｅｘのマルチフィラメント糸を使用することが好ましい。単糸繊度が３ｄｔｅｘ未満であると繊維の強度及び弾性力が弱いため保形性が悪く、コシの無いものになってしまう虞があり、６ｄｔｅｘより大きくなると、連結糸が硬い為繊維構造体の表面に飛び出し触感が悪くなったり、布帛の風合いが硬化し悪くなる虞がある。また繊度が３３ｄｔｅｘ未満であると繊維の弾性が弱いため保形性が悪くなる虞があり、１１０ｄｔｅｘより大きくなると布帛の風合いが硬化し風合いが悪くなる虞がある。連結糸がモノフィラメントであると成型時高温高圧をかけることにより、硬化し柔軟性が損なわれ布帛の保形性、圧縮反発性が悪くなったり、連結糸が地組織面に飛び出る虞があるため好ましくない。 The connecting yarn used in the present invention is preferably a multifilament yarn having a fineness of 33 to 110 dtex composed of a yarn having a single yarn fineness of 3 to 6 dtex. If the single yarn fineness is less than 3 dtex, the strength and elasticity of the fiber are weak, so the shape retention is poor, and there is a risk that it will become stiff. If it is greater than 6 dtex, the connecting yarn is hard and the fiber structure There is a possibility that the surface may protrude to the surface and feel bad, or the texture of the fabric may harden and deteriorate. If the fineness is less than 33 dtex, the shape of the fabric may be deteriorated because the elasticity of the fiber is weak. If the fineness is greater than 110 dtex, the texture of the fabric may be cured and the texture may be deteriorated. When the connecting yarn is a monofilament, it is preferable to apply high temperature and high pressure at the time of molding, because it may be hardened and the flexibility may be deteriorated, and the shape retaining property and compression resilience of the fabric may be deteriorated. Absent.
本発明においては、単糸繊度が３〜６ｄｔｅｘの糸で構成された繊度３３〜１１０ｄｔｅｘのマルチフィラメント糸を連結糸に用いることが好ましく、成型時に高温高圧が加えられても、連結糸が異なる角度で表裏の地組織を連結しているので圧力が分散され連結糸が折れることが少ないので圧縮反発性に優れる。マルチフィラメント糸を用いているため、同繊度のモノフィラメント糸に比べて加熱されても糸が硬化しにくい為布帛の柔軟性が損なわれにくく、また十分な厚み保持性、保形性や圧縮反発性を確保できる。 In the present invention, it is preferable to use a multifilament yarn having a fineness of 33 to 110 dtex composed of a yarn having a single yarn fineness of 3 to 6 dtex as the connecting yarn, and the connecting yarn has different angles even when high temperature and high pressure are applied during molding. Since the ground structures on the front and back sides are connected, the pressure is dispersed and the connecting yarn is less likely to break, so the compression resilience is excellent. Because multifilament yarns are used, the yarns are hard to cure even when heated compared to monofilament yarns of the same fineness, so the flexibility of the fabric is less likely to be impaired, and sufficient thickness retention, shape retention and compression resilience Can be secured.
また、本発明の地組織のループ数は８５０〜１４００個／吋２であることが好ましく、特に１０００〜１３００個／吋２であることが好ましい。本発明のループ数とは、立体構造経編地の地組織のコース数／吋×ウエル数／吋より求められる。ループ数が８５０個／吋２未満であると布帛の圧縮反発性、保形性が悪くなる虞があり、十分な強度が得られない虞がある。１４００個／吋２より多くなるとループの隙間が少なくなり布帛が硬くなったり重くなる虞があり、また伸縮性及び柔軟性が損なわれる虞があるので好ましくない。
In addition, the number of loops in the ground structure of the present invention is preferably 850 to 1400 pieces / 吋2 , particularly 1000 to 1300 pieces / 吋2 . The number of loops of the present invention is determined from the number of courses of the texture of the three-dimensional warp knitted fabric / 地 × number of wells / 吋 . If the number of loops is less than 850 / 吋2 , the fabric may have poor compression resilience and shape retention, and sufficient strength may not be obtained. There are 1400 pieces / inch becomes larger than 2 when a possibility that the gap is reduced fabric loop is heavy or hardened, and because stretchability and flexibility is likely to be impaired undesirably.
また、本発明の繊維構造体の連結糸の本数は１７００〜２８００本／吋２であることが好ましく、特に２０００〜２６００本／吋２が好ましい。連結糸が１７００本／吋２未満であると圧縮反発力、保形性が損なわれる虞がある。また、２８００本／吋２より多くなると布帛の伸縮性が損なわれたり、柔軟性が損なわれる虞がある。連結糸の本数は連結糸に使用している糸の単糸数×ループ数（本／吋２）×２で求められる。 Further, the number of connecting fibers of the fiber structure of the present invention, it is preferable, in particular from 2,000 to 2,600 pieces / inch 2 is preferably from 1,700 to 2,800 pieces / inch 2. If the number of connected yarns is less than 1700 / 吋2 , the compression repulsion force and shape retention may be impaired. On the other hand, if the number is more than 2800 pieces / 吋2, the stretchability of the fabric may be impaired or the flexibility may be impaired. The number of connected yarns is obtained by the number of single yarns used for the connected yarns × number of loops (number of yarns / 吋2 ) × 2.
また、布帛の厚みは２〜６ｍｍが好ましい。厚みが２ｍｍ未満であると保形性が悪くなり、圧縮反発性が損なわれたり、透けやすくなるなどの問題が発生する虞がある。また６ｍｍより厚くなると布帛が重くなったり、風合いが悪くなる虞がある。 Further, the thickness of the fabric is preferably 2 to 6 mm. If the thickness is less than 2 mm, the shape-retaining property is deteriorated, and there is a possibility that problems such as loss of compression resilience and easy penetration. Moreover, when it becomes thicker than 6 mm, there exists a possibility that a fabric may become heavy or a texture may worsen.
また、本発明の繊維構造体の重量は２５０〜３５０ｇ／ｍ２であり、好ましくは２８０〜３３０ｇ／ｍ２の範囲が好ましい。２５０ｇ／ｍ２未満であると反発力、保形性が損なわれる虞があり、３５０ｇ／ｍ２より重くなると柔軟性が損なわれる虞がある。 Moreover, the weight of the fiber structure of this invention is 250-350 g / m < 2 >, Preferably the range of 280-330 g / m < 2 > is preferable. If it is less than 250 g / m 2 , the resilience and shape retention may be impaired, and if it is heavier than 350 g / m 2 , the flexibility may be impaired.
上述の糸構成、及びループ密度、及び連結糸本数などの構成をとることにより、本発明の布帛伸度、通気度、布帛硬度を有する、積層構造にしなくても素材単体で胸衣に適した立体構造経編地を得ることができるのである。 By adopting the above-described yarn configuration, the loop density, the number of connected yarns, and the like, the material has the fabric elongation, air permeability, and fabric hardness of the present invention, and is suitable for breast clothing as a single material without a laminated structure. A three-dimensional warp knitted fabric can be obtained.
