従来、ダウンジャケット、中綿入りジャケット、防寒服、寝袋、中綿入りふとん、羽毛ふとんなど、側地用織物と中材とで構成される繊維製品は、蓄熱性と軽量性が良好であるため広く使用されている（例えば、特許文献１、特許文献２、特許文献３参照）。
しかしながら、かかる繊維製品において、蓄熱性をさらに高めるためには、側地用織物の目付けを大きくしたり、これらの繊維製品に含まれる中綿やダウンなどの中材の量を増加させる必要性があり、軽量性や着用快適性が損なわれるおそれがあった。
Conventionally, textile products composed of side fabrics and padding, such as down jackets, jackets with batting, winter clothes, sleeping bags, futons with batting, and feather futons, are widely used because they have good heat storage and light weight. (For example, see Patent Document 1, Patent Document 2, and Patent Document 3).
However, in order to further enhance the heat storage in such textile products, there is a need to increase the fabric weight of the side fabrics and to increase the amount of fillings and downs contained in these textiles.

Is provided.
その際、前記マルチフィラメントにおいて、単繊維繊度が１．３ｄｔｅｘ以下であることが好ましい。また、前記マルチフィラメントがポリエステルからなることが好ましい。また、下記式に定義するカバーファクターＣＦが１２００以上であることが好ましい。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
［ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆ

At that time, in the multifilament, it is preferable that the single fiber fineness is 1.3 dtex or less. The multifilament is preferably made of polyester. Moreover, it is preferable that the cover factor CF defined by the following formula is 1200 or more.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
[DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf

本発明によれば、軽量性を損なわずに優れた蓄熱性を有する側地用織物および繊維製品が得られる。 ADVANTAGE OF THE INVENTION According to this invention, the fabric for textiles and textiles which have the outstanding thermal storage property without impairing lightweight property are obtained.
まず、本発明の側地用織物は総繊度８０ｄｔｅｘ以下（好ましくは２０〜５０ｄｔｅｘ、特に好ましくは２０〜３５ｄｔｅｘ）のマルチフィラメントから構成される。
ここで、前記マルチフィラメントの総繊度が８０ｄｔｅｘよりも大きい場合、側地用織物の軽量性が損なわれるおそれがあり、好ましくない。
First, the side fabric of the present invention is composed of multifilaments having a total fineness of 80 dtex or less (preferably 20 to 50 dtex, particularly preferably 20 to 35 dtex).
Here, when the total fineness of the said multifilament is larger than 80 dtex, there exists a possibility that the lightweight property of the textile for side ground may be impaired, and it is unpreferable.
前記マルチフィラメントにおいて、単繊維繊度が１．３ｄｔｅｘ以下（好ましくは０．０００００１〜１．３ｄｔｅｘ）であることが好ましい。該単繊維繊度が１．３ｄｔｅｘよりも大きい場合、繊維間空隙が大きくなり側地用織物を用いて繊維製品を得た際に、蓄熱性が低下するおそれがあり、また、軽量性も損なわれるおそれがある。その際、前記マルチフィラメントはナノファイバーと称される単繊維径１０００ｎｍ以下の超極細繊維であってもよい。
前記マルチフィラメントにおいて、フィラメント数は１０〜１００００本の範囲内であることが好ましい。
In the multifilament, the single fiber fineness is preferably 1.3 dtex or less (preferably 0.000001 to 1.3 dtex). When the single fiber fineness is larger than 1.3 dtex, the inter-fiber gap becomes large, and when a textile product is obtained using the side fabric, the heat storage property may be lowered, and the lightness is also impaired. There is a fear. In this case, the multifilament may be a superfine fiber having a single fiber diameter of 1000 nm or less, called a nanofiber.
In the multifilament, the number of filaments is preferably in the range of 10 to 10,000.
前記マルチフィラメントにおいて、繊維形態は特に限定されず、長繊維（マルチフィラメント糸）でもよいし、短繊維でもよい。なかでも、織物の組織間空隙を小さくして蓄熱性を高める上で、紡績糸のように繊維が凝集しているよりも長繊維（マルチフィラメント糸）のように嵩高であるほうが好ましい。単繊維の断面形状も特に限定されず、丸、三角、扁平、くびれつき扁平、中空など公知の断面形状でよい。 In the multifilament, the fiber form is not particularly limited, and may be a long fiber (multifilament yarn) or a short fiber. Among these, in order to reduce the inter-structure voids of the woven fabric and enhance the heat storage property, it is preferable that the fibers are bulky like long fibers (multifilament yarns) rather than the fibers being aggregated like spun yarns. The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, a constricted flat shape, or a hollow shape.
前記マルチフィラメントを形成するポリマーは特に限定されないが、ポリエステル系ポリマーが好ましい。かかるポリエステル系ポリマーとしては、例えば、ポリエチレンテレフタレートやポリトリメチレンテレフタレート、ポリブチレンテレフタレート、ポリ乳酸、ステレオコンプレックスポリ乳酸、第３成分を共重合させたポリエステルなどが好ましく例示される。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、特開２００９−０９１６９４号公報に記載された、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。また、本発明の目的を損なわない範囲内で必要に応じて、艶消し剤、微細孔形成剤、カチオン染料可染剤、着色防止剤、熱安定剤、蛍光増白剤、着色剤、吸湿剤、無機微粒子が１種または２種以上含まれていてもよい。 Although the polymer which forms the said multifilament is not specifically limited, A polyester-type polymer is preferable. Preferred examples of the polyester polymer include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, stereocomplex polylactic acid, and polyester obtained by copolymerizing a third component. Examples of such polyester include material-recycled or chemical-recycled polyester, and polyethylene terephthalate using a monomer component obtained by using biomass, that is, a biological material as a raw material, described in JP-A-2009-091694. May be. 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 2004-2111268 may be sufficient. In addition, a matting agent, a fine pore forming agent, a cationic dye dyeing agent, a coloring preventing agent, a thermal stabilizer, a fluorescent brightening agent, a coloring agent, and a hygroscopic agent as necessary within the range not impairing the object of the present invention. In addition, one kind or two or more kinds of inorganic fine particles may be contained.
前記マルチフィラメントは、例えば以下の製造方法により製造することができる。すなわち、例えば、固有粘度が０．５５〜０．８０の前記ポリエステルなどを、常法により紡糸し、２０００〜４３００ｍ／分の速度で未延伸糸（中間配向糸）として一旦巻き取り、延伸するか、または、巻き取る前に延伸して、総繊度が８０ｄｔｅｘ以下のマルチフィラメントを得る。また、中間配向糸を、１８０〜２００℃に加熱されたヒーターを用いて、弛緩状態（オーバーフィード１．５〜１０％）で熱処理することにより、加熱下で自己伸長性を有する未延伸糸（中間配向糸）としてもよい。さらには、仮撚捲縮加工や空気加工や撚糸などを施してもよい。 The multifilament can be manufactured, for example, by the following manufacturing method. That is, for example, whether the polyester having an intrinsic viscosity of 0.55 to 0.80 is spun by a conventional method, wound once as an undrawn yarn (intermediate oriented yarn) at a speed of 2000 to 4300 m / min, and then drawn. Alternatively, the film is stretched before winding to obtain a multifilament having a total fineness of 80 dtex or less. In addition, the intermediate oriented yarn is heat-treated in a relaxed state (overfeed 1.5 to 10%) using a heater heated to 180 to 200 ° C., so that an undrawn yarn having self-extensibility under heating ( Intermediately oriented yarn). Furthermore, false twist crimping, air processing, twisting, or the like may be performed.

本発明の側地用織物において、前記織物の少なくとも片面上（両面でもよいが、軽量性の点で好ましくは片面のみ）に、赤外線吸収剤を含む樹脂層が積層されている。
ここで、樹脂層に含まれる赤外線吸収剤としては、波長７００〜２０００ｎｍの赤外線領域で１０％以上の吸収率を有する物質であれば特に限定されず、アンチモンドープ酸化錫（ＡＴＯ）やスズドープ酸化インジウム（ＩＴＯ）などの金属酸化物系微粒子、カーボンブラック、有機化合物の赤外線吸収色素などが例示される。特に、優れた赤外線吸収性能を得る上で、また、優れた意匠性を得る上でカーボンブラックが好ましい。また、驚くべきことに、カーボンブラックは制電性をも有している。その際、制電性としては摩擦帯電圧が３５００Ｖ以下（より好ましくは３０００Ｖ以下）であることが好ましい。前記樹脂層に赤外線吸収剤が含まれない場合は、十分な蓄熱性が得られず好ましくない。
In the fabric for side land of the present invention, a resin layer containing an infrared absorber is laminated on at least one side of the fabric (both sides may be preferable, but preferably only one side in terms of light weight).
Here, the infrared absorber contained in the resin layer is not particularly limited as long as it is a substance having an absorptance of 10% or more in an infrared region having a wavelength of 700 to 2000 nm. Antimony-doped tin oxide (ATO) or tin-doped indium oxide Examples thereof include metal oxide fine particles such as (ITO), carbon black, and infrared absorbing dyes of organic compounds. In particular, carbon black is preferable for obtaining excellent infrared absorption performance and for obtaining excellent design. Surprisingly, carbon black also has antistatic properties. At that time, as the antistatic property, the frictional voltage is preferably 3500 V or less (more preferably 3000 V or less). If the resin layer does not contain an infrared absorber, it is not preferable because sufficient heat storage properties cannot be obtained.
樹脂層に含まれる赤外線吸収剤の含有量としては、樹脂層の樹脂重量対比（固形分比）０．５重量％以上（より好ましくは０．５〜３０重量％）であることが好ましい。赤外線吸収剤の含有量が０．５重量％未満の場合、十分な蓄熱性が得られないおそれがある。 As content of the infrared absorber contained in a resin layer, it is preferable that it is 0.5 weight% or more (more preferably 0.5-30 weight%) with respect to the resin weight (solid content ratio) of a resin layer. When the content of the infrared absorber is less than 0.5% by weight, sufficient heat storage property may not be obtained.
前記樹脂層を形成する樹脂の種類としては、ウレタン樹脂、アクリル樹脂、ポリエステル樹脂、シリコーン樹脂、塩化ビニル樹脂、ナイロン樹脂など公知のバインダー樹脂でよい。また、樹脂の基布に対する付着量は、樹脂固形分基準で基布に対して０．０１〜４０ｇ／ｍ２（より好ましくは５〜３０ｇ／ｍ２）の範囲内であることが好ましい。 As a kind of resin which forms the said resin layer, well-known binder resins, such as a urethane resin, an acrylic resin, a polyester resin, a silicone resin, a vinyl chloride resin, a nylon resin, may be sufficient. Further, the amount of adhesion to the base fabric of the resin is preferably 0.01~40g / m 2 (more preferably 5 to 30 g / m 2) to the base fabric with a resin solids in the range of.
また、かかる樹脂層は織物全面に付着していてもよいが、特開２００３−９６６６３号公報に記載されているように、格子状、飛島状、市松格子状、縞上など、基布の少なくとも片面（好ましくは片面のみ）上に部分的に付着していると、軽量性の点で好ましい。
本発明の側地用織物は例えば以下の製造方法により製造することができる。すなわち、前記の織物に、赤外線吸収剤を含む樹脂配合組成物を付与する。
In addition, the resin layer may be attached to the entire surface of the fabric, but as described in JP-A-2003-96663, at least a base fabric such as a lattice shape, Tobishima shape, checkered lattice shape, stripes, etc. It is preferable in terms of light weight to be partially attached on one side (preferably only one side).
The fabric for side land of this invention can be manufactured with the following manufacturing methods, for example. That is, a resin blend composition containing an infrared absorber is applied to the woven fabric.
その際、かかる配合組成物は水系、溶剤系のいずれで構成してもよいが、加工工程の作業環境上水系の方が好ましい。溶剤としては、トルエン、イソプロピルアルコール、ジメチルホルムアミド、メチルエチルケトン、酢酸エチルなどが例示される。この配合組成物には、エポキシ系などの架橋剤を併用してもよい。さらに、織物本体に対する付着性を向上させる等の目的で適当な添加剤をさらに配合してもよい。 In this case, the blended composition may be composed of either an aqueous system or a solvent system, but an aqueous system is preferable in view of the working environment of the processing step. Examples of the solvent include toluene, isopropyl alcohol, dimethylformamide, methyl ethyl ketone, ethyl acetate and the like. This blended composition may be used in combination with an epoxy-based crosslinking agent. Furthermore, you may further mix | blend a suitable additive for the objective of improving the adhesiveness with respect to a textile main body.
織物への配合組成物の付与手段としては、グラビヤコーテイング法、スクリーンプリント法などの、公知の付与手段を用いることができる。
ここで、前記配合組成物を織物に付与する前および／または後に、織物にカレンダー加工および／または撥水加工を施すと、組織間空隙が小さくなるため、蓄熱性がさらに向上し好ましい。撥水加工としては、例えば、特許第３１３３２２７号公報や特公平４−５７８６号公報に記載された方法が好適である。すなわち、撥水剤として市販のふっ素系撥水剤（例えば、旭硝子（株）製、アサヒガードＬＳ−３１７）を使用し、必要に応じてメラミン樹脂、触媒を混合して撥水剤の濃度が３〜１５重量％程度の加工剤とし、ピックアップ率５０〜９０％程度で、該加工剤を用いて織物の表面を処理する方法である。加工剤で織物の表面を処理する方法としては、パッド法、スプレー法などが例示され、なかでも、加工剤を織物内部まで浸透させる上でパッド法が最も好ましい。なお、前記ピックアップ率とは、加工剤の織物（加工剤付与前）重量に対する重量割合（％）である。また、カレンダー加工の条件としては、温度１３０℃以上（より好ましくは１４０〜１９５℃）、線圧２００〜２００００Ｎ／ｃｍの範囲内であることが好ましい。
As means for applying the blended composition to the woven fabric, known means such as gravure coating method and screen printing method can be used.
Here, it is preferable to apply calendering and / or water repellent treatment to the woven fabric before and / or after applying the blended composition to the woven fabric, because the interstitial voids are reduced, and the heat storage property is further improved. As the water repellent treatment, for example, methods described in Japanese Patent No. 3133227 and Japanese Patent Publication No. 4-5786 are suitable. That is, a commercially available fluorine-based water repellent (for example, Asahi Guard LS-317, manufactured by Asahi Glass Co., Ltd.) is used as the water repellent, and the concentration of the water repellent is adjusted by mixing melamine resin and catalyst as necessary. In this method, the surface of the woven fabric is treated with the processing agent at a pickup rate of about 50 to 90% with a processing agent of about 3 to 15% by weight. Examples of the method for treating the surface of the woven fabric with the processing agent include a pad method and a spray method. Among them, the pad method is most preferable for allowing the processing agent to penetrate into the woven fabric. In addition, the said pick-up rate is the weight ratio (%) with respect to the textile fabric (before processing agent provision) weight of a processing agent. The calendering conditions are preferably a temperature of 130 ° C. or higher (more preferably 140 to 195 ° C.) and a linear pressure of 200 to 20000 N / cm.
さらには、常法の染色加工、起毛加工、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、バッフィング加工またはブラシ処理加工を付加適用してもよい。
かくして得られた側地用織物において、軽量性の点で目付けが１００ｇ／ｍ２以下（より好ましくは３０〜８０ｇ／ｍ２）であることが肝要である。軽量性の点では目付けは小さいほどよいが、目付けがあまり小さくなると蓄熱性が低下するおそれがあるので、３０〜８０ｇ／ｍ２の範囲が好ましい。
In addition, conventional dyeing, brushing, UV shielding or antistatic agents, antibacterial agents, deodorants, insect repellents, phosphorescent agents, retroreflective agents, negative ion generators, and other various types of processing, buffing Processing or brush processing may be additionally applied.
In the side fabric thus obtained, it is important that the basis weight is 100 g / m 2 or less (more preferably 30 to 80 g / m 2 ) in terms of lightness. In terms of light weight, the basis weight is preferably as small as possible. However, if the basis weight is too small, the heat storage property may be lowered, so the range of 30 to 80 g / m 2 is preferable.
また、側地用織物において、通気性が１ｃｃ／ｃｍ２・ｓｅｃ以下（好ましくは０．１〜１．０ｃｃ／ｃｍ２・ｓｅｃ）であることが、蓄熱性の点で好ましい。
かくして得られた側地用織物は、織物の少なくとも片面上に、赤外線吸収剤を含む樹脂層が積層されているので、優れた蓄熱性を有する。また、目付けが１００ｇ／ｍ２以下であるので軽量性にも優れる。
Further, in the side fabric, it is preferable in terms of heat storage that the air permeability is 1 cc / cm 2 · sec or less (preferably 0.1 to 1.0 cc / cm 2 · sec).
The fabric for side land thus obtained has excellent heat storage properties because a resin layer containing an infrared absorber is laminated on at least one surface of the fabric. Moreover, since the basis weight is 100 g / m 2 or less, the weight is excellent.
