本発明は、近赤外線に対して優れた遮熱性を有する遮熱性織編物および繊維製品に関する。 The present invention relates to a heat-shielding woven or knitted fabric and a fiber product having excellent heat-shielding properties for near infrared rays.
従来、夏場の炎天下などにおいて、太陽光を遮蔽するために、日傘、カーテン、日よけシートなどの繊維製品が使用されている。そして、かかる繊維製品用の織編物としては、酸化チタンなどの艶消し剤を含有する繊維を用いたものや、織編物表面に光反射性の金属膜を形成したものなどが提案されている（例えば、特許文献１、特許文献２参照）。 Conventionally, fiber products such as parasols, curtains, and sunshade sheets have been used to shield sunlight in the hot weather in summer. As such a woven or knitted fabric for textiles, one using a fiber containing a matting agent such as titanium oxide or one having a light-reflective metal film formed on the surface of the woven or knitted fabric has been proposed ( For example, see Patent Document 1 and Patent Document 2).
しかしながら、艶消し剤を含有する繊維を用いたものでは、紫外線に対しては遮蔽効果があるものの、暑さを感じる近赤外線領域での遮蔽効果は十分とはいえなかった。また、織編物表面に光反射性の金属膜を形成したものでは、工程が複雑になりかつコストアップとなり、実用的ではなかった。 However, a fiber using a matting agent-containing fiber has a shielding effect against ultraviolet rays, but the shielding effect in the near infrared region where heat is felt is not sufficient. Further, in the case where a light-reflective metal film is formed on the surface of the woven or knitted fabric, the process becomes complicated and the cost is increased, which is not practical.
本発明は上記の背景に鑑みなされたものであり、その目的は、近赤外線に対して優れた遮熱性を有する遮熱性織編物および繊維製品を提供することにある。 This invention is made | formed in view of said background, The objective is to provide the heat-insulating woven / knitted fabric and textiles which have the heat insulation outstanding with respect to near-infrared rays.

以下、本発明の実施の形態について詳細に説明する。
まず、フィラメント糸Ａ（以下、「ナノファイバー」と称することもある。）において、その単繊維径（単繊維の直径）が１０〜１０００ｎｍ（好ましくは１００〜９００ｎｍ、特に好ましくは５５０〜９００ｎｍ）の範囲内であることが肝要である。かかる単繊維径を単繊維繊度に換算すると、０．０００００１〜０．０１ｄｔｅｘに相当する。該単繊維径が１０ｎｍよりも小さい場合は繊維強度が低下するため実用上好ましくない。逆に、該単繊維径が１０００ｎｍよりも大きい場合は、近赤外線に対して優れた遮熱効果が得られず好ましくない。ここで、単繊維の断面形状が丸断面以外の異型断面である場合には、外接円の直径を単繊維径とする。なお、単繊維径は、透過型電子顕微鏡で繊維の横断面を撮影することにより測定が可能である。また、単繊維繊度のばらつきが−２０％〜＋２０％の範囲内であることが好ましい。
Hereinafter, embodiments of the present invention will be described in detail.
First, in the filament yarn A (hereinafter, also referred to as “nanofiber”), the single fiber diameter (single fiber diameter) is 10 to 1000 nm (preferably 100 to 900 nm, particularly preferably 550 to 900 nm). It is important to be within the range. When the single fiber diameter is converted into a single fiber fineness, it corresponds to 0.000001 to 0.01 dtex. When the single fiber diameter is smaller than 10 nm, the fiber strength is lowered, which is not preferable for practical use. On the other hand, when the single fiber diameter is larger than 1000 nm, an excellent heat shielding effect with respect to near infrared rays cannot be obtained, which is not preferable. Here, when the cross-sectional shape of the single fiber is an atypical cross section other than the round cross section, the diameter of the circumscribed circle is defined as the single fiber diameter. The single fiber diameter can be measured by photographing the cross section of the fiber with a transmission electron microscope. Moreover, it is preferable that the dispersion | variation in single fiber fineness exists in the range of -20%-+ 20%.
前記フィラメント糸Ａにおいて、近赤外線に対して優れた遮熱効果を得る上でフィラメント数が５００本以上（より好ましくは２０００〜１００００本）であることが肝要である。かかるフィラメント数が５００本未満の場合、近赤外線に対して優れた遮熱効果が得られないおそれがある。また、フィラメント糸Ａの総繊度（単繊維繊度とフィラメント数との積）としては、５〜１５０ｄｔｅｘの範囲内であることが好ましい。 In the filament yarn A, it is important that the number of filaments is 500 or more (more preferably 2000 to 10,000) in order to obtain an excellent heat shielding effect against near infrared rays. When the number of filaments is less than 500, there is a possibility that an excellent heat shielding effect for near infrared rays cannot be obtained. The total fineness of the filament yarn A (the product of the single fiber fineness and the number of filaments) is preferably in the range of 5 to 150 dtex.
前記フィラメント糸Ａの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、織編物の組織間空隙を小さくして近赤外線に対して優れた遮熱効果が得る上で、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、中空など公知の断面形状でよい。また、通常の空気加工、仮撚捲縮加工が施されていてもさしつかえない。 The fiber form of the filament yarn A is not particularly limited, and may be a long fiber (multifilament yarn) or a short fiber. Among them, it is more like long fibers (multifilament yarns) than fibers that are agglomerated like spun yarns in order to obtain an excellent heat shielding effect against near infrared rays by reducing the inter-structure voids of woven and knitted fabrics. It is more preferable that it is bulky. 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, or a hollow shape. In addition, normal air processing and false twist crimping may be applied.
前記フィラメント糸Ａを形成するポリマーの種類としては特に限定されないが、繊維強度や染色堅牢性などの点でポリエステル系ポリマーが好ましい。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。該ポリマー中には、本発明の目的を損なわない範囲内で必要に応じて、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、艶消し剤、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。艶消し剤（酸化チタン）はポリエステル中に含まれていてもさしつかえないが、艶消し剤がポリエステル中に含まれていなくても近赤外線に対して優れた遮熱効果が得られるので、フィラメントＡを容易に製造する上で、艶消し剤（酸化チタン）の含有量はポリエステル重量対比２．５％以下とすることが好ましい。 The type of polymer that forms the filament yarn A is not particularly limited, but a polyester polymer is preferable in terms of fiber strength and dyeing fastness. For example, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, stereocomplex polylactic acid, polyester obtained by copolymerizing the third component, and the like are preferably exemplified. 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 2004-21268 may be sufficient. In the polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent may be added as necessary within the range not impairing the object of the present invention. 1 type (s) or 2 or more types of an agent, a hygroscopic agent, and inorganic fine particles may be contained. A matting agent (titanium oxide) can be included in the polyester, but an excellent heat shielding effect against near infrared rays can be obtained even if the matting agent is not contained in the polyester. In order to produce easily, it is preferable that content of a matting agent (titanium oxide) shall be 2.5% or less with respect to polyester weight.
次に、フィラメント糸Ｂは、艶消し剤をフィラメント糸を形成するポリマー重量対比１．５重量％以上（より好ましくは２．０重量％以上、特に好ましくは２．０〜４．０重量％）含みかつ単繊維径が１０００ｎｍよりも大きいフィラメント糸である。
ここで、フィラメント糸Ｂに含まれる艶消し剤の含有量が１．５重量％未満の場合、近赤外線に対して優れた遮熱効果が得られないおそれがある。
Next, in the filament yarn B, the matting agent is 1.5% by weight or more (more preferably 2.0% by weight or more, particularly preferably 2.0 to 4.0% by weight) with respect to the polymer weight forming the filament yarn. It is a filament yarn which contains and has a single fiber diameter larger than 1000 nm.
Here, when the content of the matting agent contained in the filament yarn B is less than 1.5% by weight, an excellent heat shielding effect against near infrared rays may not be obtained.
また、フィラメント糸Ｂの単繊維径が１０００ｎｍ以下の場合、艶消し剤の含有量が大きいため紡糸が困難になるおそれがある。フィラメント糸Ｂの単繊維径の好ましい範囲は１〜２０μｍである。フィラメント糸Ｂにおいて、フィラメント数および総繊度としては、フィラメント数１０〜２００本、総繊度１０〜３５０ｄｔｅｘの範囲内であることが好ましい。
かかるフィラメント糸Ｂを形成するポリマーとしては、前記フィラメント糸Ａと同様のポリエステル系ポリマーが好ましい。
Moreover, when the single fiber diameter of the filament yarn B is 1000 nm or less, there is a possibility that spinning becomes difficult because the content of the matting agent is large. A preferable range of the single fiber diameter of the filament yarn B is 1 to 20 μm. In the filament yarn B, the number of filaments and the total fineness are preferably in the range of 10 to 200 filaments and the total fineness of 10 to 350 dtex.
As the polymer for forming the filament yarn B, a polyester polymer similar to the filament yarn A is preferable.
本発明の遮熱性織編物において、織編物に含まれる前記フィラメント糸Ａとフィラメント糸Ｂとの重量比としては、（前者：後者）１５：８５〜８０：２０の範囲内であることが好ましい。なお、本発明の遮熱性織編物は、前記フィラメント糸Ａとフィラメント糸Ｂだけで構成されることが最も好ましいが、織編物重量に対して５０重量％以下であれば他の繊維が含まれていてもよい。 In the heat-shielding woven or knitted fabric of the present invention, the weight ratio of the filament yarn A and the filament yarn B contained in the woven or knitted fabric is preferably within the range of (the former: the latter) 15:85 to 80:20. The heat-insulating woven or knitted fabric of the present invention is most preferably composed only of the filament yarn A and the filament yarn B, but other fibers are included as long as it is 50% by weight or less based on the weight of the woven or knitted fabric. May be.
前記フィラメント糸Ａとフィラメント糸Ｂとは、複合糸として織編物に含まれていてもよいし、両者が引き揃えられて含まれていてもよいし、両者が交編または交織されていてもよい。特に、近赤外線に対して優れた遮熱効果を得る上で両者が交編または交織されていることが好ましい。 The filament yarn A and the filament yarn B may be included in a woven or knitted fabric as a composite yarn, or both may be included by being aligned, or both may be knitted or woven. . In particular, it is preferable that the two are knitted or woven in order to obtain an excellent heat shielding effect against near infrared rays.

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
は緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。］
In addition, it is preferable that the woven or knitted fabric is a woven fabric having a cover factor CF defined by the following formula of 1200 or more (more preferably 1400 to 5000) because a particularly excellent heat shielding effect is obtained.

一方、島成分ポリマーは、最終的にフィラメントＡを形成するポリマーであり、前記のようなのポリエステルが好ましい。該ポリマー中には、本発明の目的を損なわない範囲内で必要に応じて、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、艶消し剤、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。 On the other hand, the island component polymer is a polymer that finally forms the filament A, and the polyester as described above is preferable. In the polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent may be added as necessary within the range not impairing the object of the present invention. 1 type (s) or 2 or more types of an agent, a hygroscopic agent, and inorganic fine particles may be contained.
上記の海成分ポリマーと島成分ポリマーからなる海島型複合繊維は、溶融紡糸時における海成分の溶融粘度が島成分ポリマーの溶融粘度よりも大きいことが好ましい。また、島成分の径は、１０〜１０００ｎｍの範囲とする必要がある。その際、該径が真円でない場合は外接円の直径を求める。前記の海島型複合繊維において、その海島複合重量比率（海：島）は、４０：６０〜５：９５の範囲が好ましく、特に３０：７０〜１０：９０の範囲が好ましい。 The sea-island composite fiber composed of the sea component polymer and the island component polymer preferably has a sea component melt viscosity higher than that of the island component polymer during melt spinning. Further, the diameter of the island component needs to be in the range of 10 to 1000 nm. At this time, if the diameter is not a perfect circle, the diameter of the circumscribed circle is obtained. In the sea-island composite fiber, the sea-island composite weight ratio (sea: island) is preferably in the range of 40:60 to 5:95, and particularly preferably in the range of 30:70 to 10:90.

That is, melt spinning is performed using the sea component polymer and the island component polymer. As the spinneret used for melt spinning, any one such as a hollow pin group for forming an island component or a group having a fine hole group can be used. The discharged sea-island type composite fiber (multifilament) is solidified by cooling air, and is preferably wound after being melt-spun at 400 to 6000 m / min. The obtained undrawn yarn is made into a composite fiber having desired strength, elongation, and heat shrinkage properties through a separate drawing process, or is taken up by a roller at a constant speed without being wound once, and subsequently drawn. Any of the methods of winding after passing through may be used. Further, false twist crimping may be performed.

It is preferable to be within a range of ˜170 dtex (preferably 30 to 100 dtex). Here, when the number of filaments of the filament A finally obtained is 500 or more, it is important that the product of the number of islands of the island component and the number of filaments of the sea-island type composite fiber is 500 or more. .
また、艶消し剤を１．５重量％以上含みかつ単繊維径が１０００ｎｍよりも大きいフィラメント糸Ｂを用意する。
次いで、前記海島型複合繊維（フィラメント糸Ａ用マルチフィラメント）とフィラメント糸Ｂとを用いて、さらに必要に応じて他の繊維（弾性繊維やポリエステル繊維など）をも用いて前記のような織編物を製編織する。
Also, a filament yarn B containing a matting agent of 1.5% by weight or more and having a single fiber diameter larger than 1000 nm is prepared.
Next, using the sea-island type composite fiber (multifilament for filament yarn A) and filament yarn B, and further using other fibers (elastic fiber, polyester fiber, etc.) as necessary, the woven or knitted fabric as described above Weaving and weaving.
次いで、該織編物にアルカリ水溶液処理を施し、前記海島型複合繊維の海成分をアルカリ水溶液で溶解除去し、海島型複合繊維を単繊維径が１０〜１０００ｎｍのフィラメント糸Ａとすることにより、単繊維径が１０〜１０００ｎｍでありかつフィラメント数が５００本以上のフィラメント糸Ａと、艶消し剤を１．５重量％以上含みかつ単繊維径が１０００ｎｍよりも大きいフィラメント糸Ｂとを含む織編物を得る。その際、アルカリ水溶液処理の条件としては、濃度３〜４％のＮａＯＨ水溶液を使用し５５〜６５℃の温度で処理するとよい。 Next, the woven or knitted fabric is subjected to an alkaline aqueous solution treatment, and sea components of the sea-island type composite fibers are dissolved and removed with an alkaline aqueous solution, whereby the sea-island type composite fibers are made into filament yarns A having a single fiber diameter of 10 to 1000 nm. A woven or knitted fabric comprising a filament yarn A having a fiber diameter of 10 to 1000 nm and a number of filaments of 500 or more, and a filament yarn B containing a matting agent of 1.5% by weight or more and a single fiber diameter larger than 1000 nm. obtain.

Moreover, it is preferable to apply to the circular knitted fabric because it exhibits a texture with excellent slime feeling.
かくして得られた織編物は、太陽光の近赤外線に対して優れた遮熱性を有する。その理由は、フィラメント糸Ｂに含まれる艶消し剤により近赤外線が反射されると同時に、極細繊維（フィラメント糸Ａ）と、極細繊維間に存在する微小な空気層との界面が多いため入射した近赤外線が反射されるためであろうと推定している。

The woven or knitted fabric thus obtained has an excellent heat shielding property against the near infrared rays of sunlight. The reason is that near-infrared rays are reflected by the matting agent contained in the filament yarn B, and at the same time, there are many interfaces between the ultrafine fibers (filament yarn A) and the minute air layer existing between the ultrafine fibers. It is estimated that this is because near infrared rays are reflected.
Here, the heat shielding property of the woven or knitted fabric is preferably 70% or more by measuring the average reflectance of near infrared rays having a wavelength of 0.78 to 2 μm using “UV3100S MPC-3100” manufactured by Shimadzu Corporation.

In addition, in order to make water-proof pressure 35 cm or more, it can obtain easily by employ | adopting the said woven / knitting structure and density using the said filament yarn A and the filament yarn B.
