本発明によれば、嵩高性・軽量性などの物性安定性に優れた紡績糸および布帛および繊維製品が得られる。 According to the present invention, a spun yarn, a fabric and a fiber product excellent in physical property stability such as bulkiness and lightness can be obtained.
以下、本発明の実施の形態について詳細に説明する。まず、本発明の紡績糸に含まれる合成繊維について説明する。
まず、前記合成繊維を形成するポリマーとしては特に限定されず、ポリエステル、ナイロン、ポリプロピレン、ポリエチレン、ポリ塩化ビニルなどが例示されるが、なかでもポリエステルが好ましい。
Hereinafter, embodiments of the present invention will be described in detail. First, the synthetic fiber contained in the spun yarn of the present invention will be described.
First, the polymer forming the synthetic fiber is not particularly limited, and examples thereof include polyester, nylon, polypropylene, polyethylene, polyvinyl chloride, and the like. Among these, polyester is preferable.
ポリエステルは、テレフタル酸を主たるジカルボン酸成分とし、エチレングリコール、１，３−プロパンジオール、１，４−ブタンジオール、１，５−ペンタンジオール、１，６−ヘキサンジオールなどのアルキレングリコールを主たるジオール成分とするポリエステルを８０重量％以上、好ましくは９０重量％以上含有するポリエステルであり、該ポリエステルには、本発明の目的を損なわない範囲内で、例えばイソフタル酸、ナフタレンジカルボン酸、ジフェニルジカルボン酸などの芳香族ジカルボン酸成分や上記とは異なる他のグリコール成分を共重合していてもよい。かかるポリエステルとしては、マテリアルリサイクルまたはケミカルリサイクルされたポリエステルや、バイオマスすなわち生物由来の物質を原材料として得られたモノマー成分を使用してなるポリエチレンテレフタレートであってもよい。さらには、特開２００４−２７００９７号公報や特開２００４−２１１２６８号公報に記載されているような、特定のリン化合物およびチタン化合物を含む触媒を用いて得られたポリエステルでもよい。 Polyester includes terephthalic acid as the main dicarboxylic acid component, and diol components as the main alkylene glycol such as ethylene glycol, 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, and 1,6-hexanediol. The polyester contains 80% by weight or more, preferably 90% by weight or more, and the polyester includes, for example, isophthalic acid, naphthalenedicarboxylic acid, diphenyldicarboxylic acid and the like within a range not impairing the object of the present invention. An aromatic dicarboxylic acid component or another glycol component different from the above may be copolymerized. Such polyester may be material-recycled or chemical-recycled polyester or polyethylene terephthalate using a monomer component obtained using biomass, that is, a biological material as a raw material. Furthermore, the polyester obtained using the catalyst containing the specific phosphorus compound and titanium compound which are described in Unexamined-Japanese-Patent No. 2004-270097 and 2004-21268 may be sufficient.
かかるポリエステルの固有粘度（オルソクロロフェノールを溶媒として使用し３５℃で測定）は、通常衣料用布帛素材として使用されるポリエステルと同じ範疇の０．５５〜０．８０の範囲のものが好ましい。また、必要に応じて適宜艶消し剤、制電剤、安定剤などの添加剤またはアルカリ減量により繊維表面に微細孔やフィブリルを形成させることのできる添加剤などを含んでもよい。 The intrinsic viscosity of the polyester (measured at 35 ° C. using orthochlorophenol as a solvent) is preferably in the range of 0.55 to 0.80, which is the same category as the polyester used as a fabric material for clothing. Further, if necessary, an additive such as a matting agent, an antistatic agent and a stabilizer or an additive capable of forming micropores and fibrils on the fiber surface by alkali weight reduction may be included.
合成繊維の単繊維断面形状として図１に示されているように、繊維軸に対して直交する断面が四角中空であるコアー部と、該コアー部外表面からコアー部中心点に対して放射状に突出し且つ該コアー部の長さ方向に沿って延在する８枚以上（好ましくは８〜１２枚）のフィン部とからなる形状が必要である。まず、コアー部の中空部分の形状は特開２０１０−２７５６６８号の図３に示されているような紡糸口金各吐出スリットを用いることにより、四角中空とすることおよび吐出ポリマー同士の高い貼り合せ性を得ることでき、安定して目的の単糸断面形状をえることができる。なお、図１はフィン部の枚数が８枚のものを例示しているが、本発明において８枚には限定されない。 As shown in FIG. 1 as a single fiber cross-sectional shape of a synthetic fiber, a core portion whose cross section perpendicular to the fiber axis is a square hollow, and radially from the core portion outer surface to the core portion center point The shape which consists of 8 or more (preferably 8-12 sheets) fin parts which protrude and extend along the length direction of this core part is required. First, the shape of the hollow part of the core part is a square hollow by using each spinneret discharge slit as shown in FIG. 3 of JP 2010-275668, and the high bonding property between the discharge polymers. And a desired single yarn cross-sectional shape can be obtained stably. FIG. 1 illustrates an example in which the number of fin portions is eight, but the present invention is not limited to eight.
コアー部中空部分の形状が丸形中空の場合、紡糸時での貼り合せ不良（貼り合わせ部を多くする必要があるため）による単糸断面変形が多発し断糸による工程通過性が著しく低下する。 When the shape of the hollow part of the core part is round and hollow, the single yarn cross-sectional deformation frequently occurs due to poor bonding during spinning (because it is necessary to increase the number of bonded parts), and the process passability due to broken yarn is significantly reduced. .
フィン部については、該コアー部外表面からコアー部中心点に対して放射状に突出し且つ該コアー部の長さ方向に沿って延在する８枚以上のフィン部とからなる形状にすることでマルチフィラメント状態での単糸間の干渉による高い体積排除効果をえることができ目的の空隙形成率をえることができる。
またフィンの個数を８枚以上とすることにより繊維間摩擦係数が低下するので延伸時の毛羽や断糸の発生が少ないという効果がある。
As for the fin portion, a multi-piece is formed by forming a shape including eight or more fin portions that project radially from the outer surface of the core portion to the center point of the core portion and extend along the length direction of the core portion. A high volume exclusion effect due to interference between single yarns in the filament state can be obtained, and the desired void formation rate can be obtained.
Further, when the number of fins is set to 8 or more, the inter-fiber friction coefficient is reduced, so that there is an effect that generation of fuzz and yarn breakage during stretching is small.
また、合成繊維の総繊度としては２０〜４００ｄｔｅｘであることが好ましい。２０ｄｔｅｘ未満であれば嵩高性が不足し、４００ｄｔｅｘを超える場合は風合いが硬くなり好ましくない。好ましくは２０〜２００ｄｔｅｘである。
また、合成繊維は短繊維の集合体でもよいが、フィラメント糸（長繊維）であることが好ましい、特にポリエステルフィラメント糸が好ましい。
The total fineness of the synthetic fiber is preferably 20 to 400 dtex. If it is less than 20 dtex, the bulkiness is insufficient, and if it exceeds 400 dtex, the texture becomes hard. Preferably it is 20-200 dtex.
The synthetic fiber may be an aggregate of short fibers, but is preferably a filament yarn (long fiber), particularly preferably a polyester filament yarn.
その際、単糸数は５０本以下であることが好ましい。単糸数が５０本より大であればフィンを取り付けた事による体積排除効果が十分でなく、目的とする嵩高さ、軽量感を得ることが出来ない。また単糸数が１０本より小となると（マルチフィラメントとしての繊度が小さくなると）繊維の曲げ剛性が高くなり布帛におけるソフト感が低下し好ましくない。好ましくは１０〜５０本である。
前記合成繊維の製造方法としては、特開２０１０−２７５６６８号の図３に模式的に示す吐出形状を有する口金を用いて公知の溶融紡糸、延伸法により行なうことができる。
At that time, the number of single yarns is preferably 50 or less. If the number of single yarns is greater than 50, the volume exclusion effect due to the attachment of fins is not sufficient, and the intended bulkiness and lightness cannot be obtained. On the other hand, if the number of single yarns is less than 10 (if the fineness as a multifilament becomes small), the bending rigidity of the fibers becomes high and the soft feeling in the fabric is lowered, which is not preferable. Preferably it is 10-50.
The synthetic fiber can be produced by a known melt spinning and drawing method using a die having a discharge shape schematically shown in FIG. 3 of JP 2010-275668.
本発明の紡績糸は前記のポリエステル繊維を含むものである。かかる紡績糸は前記のポリエステル繊維からなる短繊維を用いて常法により得られた紡績糸でもよいが、芯鞘構造を有し、かつ前記合成繊維が芯部に配されてなる紡績糸が好ましい。
ここで、鞘成分の短繊維は、は綿繊維（コットン）、麻、羊毛などの天然繊維、レーヨン、キュプラ、アセテートなどの化学繊維、ポリエチレンテレフタレート、ナイロン、アクリル系等の合成繊維のいずれかまたはこれらの組み合わせであってもよい。このうち好ましいのは綿繊維もしくは綿繊維と合成繊維の混紡である。綿繊維は吸水性、吸湿性も高く、肌にも良いからである。
The spun yarn of the present invention contains the polyester fiber. The spun yarn may be a spun yarn obtained by a conventional method using the short fiber made of the polyester fiber, but a spun yarn having a core-sheath structure and having the synthetic fiber arranged in the core is preferable. .
Here, the short fiber of the sheath component is one of a natural fiber such as cotton fiber (cotton), hemp and wool, a chemical fiber such as rayon, cupra and acetate, a synthetic fiber such as polyethylene terephthalate, nylon and acrylic, or A combination of these may also be used. Of these, cotton fibers or a blend of cotton fibers and synthetic fibers is preferable. This is because cotton fibers have high water absorption and hygroscopic properties, and are good for the skin.
前記のような芯鞘構造を有する紡績糸はコアスパン糸とも称され、例えば、特開２０１５−３４３５４号公報の実施例１に記載の方法により製造することができる。
本発明の紡績糸は前記の構成を有するので、嵩高性や物性安定性に優れる。
The spun yarn having the core-sheath structure as described above is also referred to as a core spun yarn, and can be manufactured by, for example, the method described in Example 1 of Japanese Patent Application Laid-Open No. 2015-34354.
Since the spun yarn of the present invention has the above-described configuration, it is excellent in bulkiness and physical property stability.
次に、本発明の布帛は前記の紡績糸を含む布帛である。布帛の組織は特に限定されないが、通常の織機または編機により製編織された織物または編物であることが好ましい。もちろん、不織布や、マトリックス繊維と熱接着性繊維とからなる繊維構造体でもよい。例えば、織物の織組織としては、平織、綾織、朱子織等の三原組織、変化組織、たて二重織、よこ二重織等の片二重組織、たてビロードなどが例示される。編物の種類は、丸編物（よこ編物）であってもよいしたて編物であってもよい。丸編物（よこ編物）の組織としては、平編、ゴム編、両面編、パール編、タック編、浮き編、片畔編、レース編、添え毛編等が好ましく例示され、たて編組織としては、シングルデンビー編、シングルアトラス編、ダブルコード編、ハーフトリコット編、裏毛編、ジャガード編等が例示される。層数も単層でもよいし、２層以上の多層でもよい。さらには、カットパイルおよび／またはループパイルからなる立毛部と地組織部とで構成される立毛布帛であってもよい。 Next, the fabric of the present invention is a fabric including the spun yarn. The structure of the fabric is not particularly limited, but is preferably a woven fabric or a knitted fabric knitted and woven by a normal loom or knitting machine. Of course, a non-woven fabric or a fiber structure composed of matrix fibers and heat-bondable fibers may be used. For example, examples of the woven structure of the woven fabric include a three-layer structure such as plain weave, twill weave and satin weave, a change structure, a single double structure such as a vertical double weave and a horizontal double weave, and a vertical velvet.
