Description
本発明は、太陽光等に含まれる赤外線を遮蔽することで衣服内の温度上昇を抑制し、衣服内環境を快適に保つための布帛に関する。 The present invention relates to a fabric for keeping a comfortable environment in clothes by suppressing an increase in temperature in clothes by shielding infrared rays contained in sunlight or the like.
近年、直射日光下で着用しても衣服内の温度上昇を抑制し、衣服内環境を快適に保つための繊維及び布帛に対する要望が強く求められ、種々の技術が検討・開示されている。 In recent years, there has been a strong demand for fibers and fabrics for suppressing temperature rise in clothes even when worn in direct sunlight and keeping the environment in clothes comfortable, and various techniques have been studied and disclosed.
特許文献１には、繊維基布上に酸化チタンなどの不定形無機化合物粒子を含む遮熱膜剤が開示されている。しかし、高い遮熱性を求める場合では十分な隠蔽力、赤外線遮蔽性を得るためには多量の不定形無機化合物粒子を必要とするため、風合い、洗濯耐久性、耐摩耗性に影響があるため限界がある。
特許文献２，３には、合成繊維中に赤外線反射性の無機微粒子、セラミックスを練り込んだ繊維及びそれを製織編してなる遮光体が開示されているが、適用されるのは合成繊維のみであり、また、多量の粒子を添加した場合には、染色性に影響を与えたり、糸強度を低下させる等問題が発生する虞があり、十分な遮熱性が得られにくい。
Patent Document 1 discloses a thermal barrier film agent containing amorphous inorganic compound particles such as titanium oxide on a fiber base fabric. However, when high heat-shielding properties are required, a large amount of amorphous inorganic compound particles are required to obtain sufficient hiding power and infrared shielding properties, so the texture, washing durability, and wear resistance are affected. There is.
Patent Documents 2 and 3 disclose a fiber in which infrared-reflective inorganic fine particles and ceramics are kneaded in a synthetic fiber and a light-shielding body obtained by weaving and knitting it, but only synthetic fibers are applied. In addition, when a large amount of particles is added, there is a possibility that problems such as affecting dyeability and lowering the yarn strength may occur, and it is difficult to obtain sufficient heat shielding properties.
また、特許文献４，５には、熱線反射性の有機微粒子ポリマーをバインダーを用いて繊維表面に固着させた涼感性繊維が提案されているが、熱線の遮蔽能力としては不十分である。 Patent Documents 4 and 5 propose cool-sensitive fibers in which a heat ray reflective organic fine particle polymer is fixed to the fiber surface using a binder, but the heat ray shielding ability is insufficient.
また、特許文献６には、チタン等の熱線反射金属をバインダーで付着させた防暑布帛が開示されているが、その付着面は外側であるため外観、意匠的にも制限されたものであった。 Further, Patent Document 6 discloses a heat-resistant fabric in which a heat ray reflective metal such as titanium is adhered with a binder, but since the adhesion surface is outside, the appearance and the design are limited. .
本発明は、太陽光等に含まれる赤外線を遮蔽することで衣服内温度の上昇を抑制できる遮熱性布帛を提供する。 The present invention provides a heat-shielding fabric that can suppress an increase in the temperature in clothes by shielding infrared rays contained in sunlight or the like.

Further, (3) is characterized in that the fiber fabric in which the glittering metal fine particles and the ceramic white pigment are partially fixed has a heat shielding property of 1 ° C. or higher with respect to the unprocessed fabric (1) or ( The heat-insulating fabric according to 2).
(4) The heat-shielding fabric according to any one of (1) to (3), wherein the glittering metal fine particles are scaly aluminum and the ceramic white pigment is titanium oxide. .
Further, in (5), the heat-shielding fabric according to any one of (1) to (4) is used, and the surface formed by partially fixing the glittering metal fine particles and the ceramic white pigment is arranged inside. It is the clothes characterized by becoming.
本発明によれば、真夏の日差しのような強い赤外線を照射された場合であっても衣服内の温度上昇を抑えることができる繊維製品を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where intense infrared rays like the midsummer sunlight are irradiated, the textiles which can suppress the temperature rise in clothes can be provided.
本発明でいう繊維布帛としては、ナイロン６，ナイロン６６で代表されるポリアミド系合成繊維、ポリエチレンテレフタレートで代表されるポリエステル系合成繊維、ポリアクリルニトリル系合成繊維、ポリビニルアルコール系合成繊維や、トリアセテート等の半合成繊維、あるいは、ナイロン６／木綿、ポリエチレンテレフタレート／木綿等の合成繊維と天然繊維の混合繊維からなる織物、編物、不織布等を挙げることができ特に限定されるものではない。 Examples of the fiber fabric used in the present invention include polyamide-based synthetic fibers represented by nylon 6, nylon 66, polyester-based synthetic fibers represented by polyethylene terephthalate, polyacrylonitrile-based synthetic fibers, polyvinyl alcohol-based synthetic fibers, and triacetate. Or a woven fabric, a knitted fabric, a non-woven fabric or the like made of a mixed fiber of natural fibers and synthetic fibers such as nylon 6 / cotton, polyethylene terephthalate / cotton, and the like.
本発明に用いることのできる光輝性金属微粒子としては、赤外線を反射、遮蔽するものであればよく、金、銀、アルミニウム等の単体微粉末が挙げられるが、重量、コスト、加工性の面からアルミニウムが好ましく用いられる。 The glittering metal fine particles that can be used in the present invention are not limited as long as they reflect and shield infrared rays, and include simple powders such as gold, silver, and aluminum. From the viewpoint of weight, cost, and workability. Aluminum is preferably used.
光輝性金属微粒子の粒子径は０．１〜１００μｍであることが好ましく、更に、０．１〜６０μｍであることが好ましい。０．１μｍ未満であると、赤外線が透過しやすくなり、遮蔽性能が低下しやすくなる。１００μｍを超えると洗濯や摩耗により粒子が脱落し易くなる傾向にある。 The particle diameter of the glittering metal fine particles is preferably 0.1 to 100 μm, and more preferably 0.1 to 60 μm. When the thickness is less than 0.1 μm, infrared rays are easily transmitted, and the shielding performance is likely to be lowered. If it exceeds 100 μm, particles tend to fall off due to washing or wear.
また、光輝性金属微粒子の形状としては鱗片状であることが好ましく、そのアスペクト比は１．０〜３．０であることが好ましい。鱗片状にした場合は少ない使用量で優れた赤外線遮蔽性を示す。
しかし、鱗片状アルミニウムを単独で使用した場合、繊維布帛表面の凹凸により鱗片状粒子が整列しにくくなることで、反射性能が低下し赤外線を吸収しやすくなる。この場合、繊維布帛の生地表面温度は高くなり易くなるため好ましくない。
The shape of the glittering metal fine particles is preferably scaly, and the aspect ratio is preferably 1.0 to 3.0. In the case of a scale, excellent infrared shielding properties are exhibited with a small amount of use.
However, when scaly aluminum is used alone, it becomes difficult for the scaly particles to be aligned due to the irregularities on the surface of the fiber fabric, so that the reflective performance is reduced and infrared rays are easily absorbed. In this case, the fabric surface temperature of the fiber fabric tends to increase, which is not preferable.
また、本発明で用いることのできるセラミックス系白色顔料としては、酸化チタン、酸化マグネシウムや酸化亜鉛などの金属酸化物を単独若しくは混合して使用することができるが、屈折率の点で酸化チタンが好ましい。
セラミックス系白色顔料の粒径は２μｍ以下、特に０．１〜１．５μｍのものを使用することが好ましい。２μｍより大きいと比重が重いことにより樹脂液中で沈降等が発生するとともに、固着表面がざらついたり、洗濯や摩耗による脱落等の問題が発生する虞がある。
更に、その形状は鱗片状、略球状、破砕状や不定形状等のものを用いることができる。球状、破砕状、不定形状のセラミックス系白色顔料を用いた場合、コスト、加工性の点のみならず、素材表面の凹凸に影響を受けずに赤外線を乱反射するため生地温度の上昇は低く抑えられるため好ましい。しかし、充分な遮蔽性能を得る為には多量のセラミックス白色顔料が必要となり、風合いが硬くなる虞がある。
Further, as the ceramic white pigment that can be used in the present invention, metal oxides such as titanium oxide, magnesium oxide, and zinc oxide can be used alone or in combination. preferable.
The particle size of the ceramic white pigment is preferably 2 μm or less, particularly 0.1 to 1.5 μm. If it is larger than 2 μm, the specific gravity is heavy, so that sedimentation or the like occurs in the resin liquid, and the fixing surface may become rough, and problems such as washing or falling off due to wear may occur.
Furthermore, the thing of scale shape, substantially spherical shape, crushed shape, indefinite shape, etc. can be used. When spherical, crushed, and irregular shaped ceramic white pigments are used, not only cost and processability, but also irregular reflection on the surface of the material, so that infrared rays are diffusely reflected, so the rise in fabric temperature can be kept low. Therefore, it is preferable. However, in order to obtain sufficient shielding performance, a large amount of ceramic white pigment is required, and the texture may become hard.
上記の欠点を解決し、より高い遮熱性を得るために、赤外線遮蔽性の高い光輝性金属微粒子と赤外線反射能の高いセラミックス系白色顔料を併用することで、繊維布帛の赤外線吸収を極力抑えつつも、高い遮熱性を得ることが可能となる。 In order to solve the above-mentioned drawbacks and obtain higher heat shielding properties, it is possible to suppress infrared absorption of the fiber fabric as much as possible by using a combination of bright metallic fine particles having high infrared shielding properties and ceramic white pigments having high infrared reflecting ability. However, it is possible to obtain a high heat shielding property.
光輝性金属微粒子に対するセラミックス系白色顔料の重量比率については１：０．１〜１０であることが好ましい。１：０．１以下であるとセラミックス系白色顔料に起因する白度や赤外線反射性が十分得られず、赤外線照射時に生地温度が上昇しやすくなる。１：１０以上であると光輝性金属微粒子の赤外線遮蔽性が得らえにくくなるため遮熱性が十分得られない虞がある。 The weight ratio of the ceramic white pigment to the glittering fine metal particles is preferably 1: 0.1 to 10. When the ratio is 1: 0.1 or less, the whiteness and infrared reflectivity resulting from the ceramic white pigment cannot be sufficiently obtained, and the dough temperature tends to increase during infrared irradiation. When the ratio is 1:10 or more, it is difficult to obtain the infrared shielding property of the glittering metal fine particles, so that the heat shielding property may not be sufficiently obtained.
また、本発明においては、光輝性金属微粒子とセラミックス系白色顔料の固着面を肌面（内側）に用いて衣服として使用することが好ましい。光輝性金属微粒子とセラミックス系白色顔料の複合による高い赤外線遮蔽性と赤外線反射性により、赤外線照射面に対して生地を介した反対面に固着したにも関わらず、高い遮熱性を有し、生地温度の上昇も最小限に抑えることが可能となる。また、固着面を肌側に使用することで繊維布帛素材本来の外観、色目に影響を与えることが少なくなり、意匠性が必要とされる衣服用途に広く使用できる。 Moreover, in this invention, it is preferable to use it as clothes using the fixed surface of a glittering metal microparticle and a ceramic white pigment on the skin surface (inner side). High heat-shielding and infrared reflectiveness due to the combination of glittering metal fine particles and ceramic white pigment, the fabric has high heat-shielding properties despite being attached to the opposite surface of the infrared-irradiated surface through the fabric. The rise in temperature can be minimized. Further, by using the fixing surface on the skin side, the fiber fabric material has less influence on the original appearance and color, and can be widely used in clothing applications that require design.
光輝性金属微粒子とセラミックス系白色顔料は繊維布帛の表面に１０〜８０％の面積比率で固着されることが好ましい。被覆面積が１０％未満であると十分な遮熱効果が得られず、８０％より多いと風合いが堅くなるとともに、特に織物素材の場合では引裂き強度、通気性の低下等の問題が発生する虞がある。 The glittering metal fine particles and the ceramic white pigment are preferably fixed to the surface of the fiber fabric at an area ratio of 10 to 80%. If the covering area is less than 10%, a sufficient heat shielding effect cannot be obtained, and if it exceeds 80%, the texture becomes stiff, and particularly in the case of a woven material, problems such as a decrease in tear strength and air permeability may occur. There is.
光輝性金属微粒子とセラミックス系白色顔料の固着量は乾燥状態で塗布面積あたり０．
５〜５g／ｍ２の範囲にあることが好ましい。０．５ｇ／ｍ２未満では十分な遮熱性が得られず、５ｇ／ｍ２より多い場合には遮熱性については必要量以上となり、性能の向上が見込めないばかりか、コストＵＰ、風合いの硬化、脱落が生じ易くなる等の問題が発生する虞がある。
The fixed amount of the glittering metal fine particles and the ceramic white pigment is 0. 0 per coated area in a dry state.
It is preferable that it exists in the range of 5-5 g / m < 2 >. If it is less than 0.5 g / m 2 , sufficient heat shielding properties cannot be obtained, and if it is more than 5 g / m 2 , the heat shielding properties will exceed the required amount, and not only an improvement in performance can be expected, but also cost increases and texture hardening. There is a risk that problems such as falling off easily occur.
光輝性金属微粒子とセラミックス系白色顔料を固着するための樹脂については ポリウレタン、ポリアクリル、ポリエステル、シリコーン樹脂等が用いられ、特に限定されるものではない。これらの樹脂は単独または複合して使用してもよく、密着性、洗濯耐久性を向上させるために架橋剤を併用してもよい。 As the resin for fixing the glittering metal fine particles and the ceramic white pigment, polyurethane, polyacryl, polyester, silicone resin and the like are used, and are not particularly limited. These resins may be used alone or in combination, and a crosslinking agent may be used in combination in order to improve adhesion and washing durability.
光輝性金属微粒子とセラミックス系白色顔料を繊維布帛に固着させるための樹脂量は光輝性金属微粒子とセラミックス系白色顔料の重量に対して固形分換算にて２〜２０倍であることが好ましい。２倍未満では十分に固着できず、洗濯耐久性、磨耗に対して十分でない。２０倍より多いと風合いが硬くなる等の問題が発生する虞がある。 The amount of resin for fixing the glittering metal fine particles and the ceramic white pigment to the fiber fabric is preferably 2 to 20 times in terms of solid content with respect to the weight of the glittering metal fine particles and the ceramic white pigment. If it is less than 2 times, it cannot be fixed sufficiently and is not sufficient for washing durability and wear. If it is more than 20 times, there is a risk of problems such as a hard texture.

また、捺染方式の場合では、樹脂液粘度を５０００〜５００００ｃｐｓに調整後、５０〜１５０メッシュのスクリーンを用いて捺染を行う。
As a method for fixing the glittering metal fine particles and the ceramic white pigment of the present invention, a gravure coating or a printing method is used.
In the case of the gravure coating method, a powder or dispersion of glittering metal fine particles and ceramic white pigment is dispersed in a resin liquid and adjusted to a viscosity of about 200 to 2000 cps, and then a gravure of 25 to 500 mesh and a depth of 20 to 200 μm. Coating is performed using a roll.
In the case of the textile printing method, after adjusting the resin liquid viscosity to 5000 to 50000 cps, printing is performed using a 50 to 150 mesh screen.

[Comparative Example 3]
Except having changed the resin liquid into the following resin prescription 5 (viscosity 35000 cps), it processed like Example 1 and obtained the heat insulation cloth. The evaluation results are shown in Table 1. As a result of using titanium oxide alone, the infrared shielding effect is lower than that used in combination with scaly aluminum, and as a result, the temperature difference is only 0.9 ° C. relative to Comparative Example 1 and is insufficient as a heat shielding fabric. It was a thing.
