Description

【0001】
【発明の属する技術分野】
本発明は、赤外線による暗視・透視撮影が可能なカメラに対し、赤外線を吸収あるいは反射することにより透視を防ぐ性能を有する肌面当接用繊維材料及び衣料に関し、特にスポーツ衣料等の薄地素材といった肌に密着させて着用する衣料に利用される繊維材料とその衣料に関する。
【0002】
【従来の技術】
近年、ビデオカメラの普及に伴い実に多様な機能が付加され、暗闇での撮影、すなわち暗視撮影が可能なものも上市されている。
この暗視撮影の原理は次の通りである。
現在、一般に普及しているビデオカメラのCCDレンズは、可視光線と赤外線、紫外線を捕らえているが、カメラ本体に赤外線と紫外線を吸収するシールドが内蔵されており、このシールドでCCDレンズが捕らえた映像の色彩、色調を補正し、自然に近い映像をファインダーに映し出している。この内蔵されている赤外線を吸収するシールドを除去することで、赤外線での撮影が可能となり、更に可視光線をカットするフィルターを装着すると、色彩識別の情報処理が単純化され、暗闇での素粒子現象が抑えられることで暗闇における暗視撮影が可能となる。
市販されている暗視撮影が可能なビデオカメラは、物理的、電気的に上記の赤外線を吸収するシールドを除去している。また暗視撮影機能を持たないカメラも、容易に暗視撮影可能なカメラに改造することができる。
【0003】
この暗視撮影機能を太陽光の下など赤外線の多い条件下で使用すると、衣料の透視ということにも利用されてしまうことがわかった。これは、赤外線が衣料を直進透過してしまうのに対し、人間の肌には反射され、この反射された赤外線を人間裸体の像として捕らえることにより可能となっていると考えられる。この様に暗視撮影機能は、暗闇での暗視という目的以外に、水着などの肌に密着した衣料を透視し、非人道的な行為に利用される事があり、社会的な問題を生じている。
【0004】
このような赤外線による透視を防ぐには、特に赤外線撮影に使用される780〜1500nmの波長を持つ赤外線を衣料が吸収あるいは反射し、赤外線を肌にまで到達させない、または肌側からの赤外線を衣料の外に出さないようにすることが考えられる。
従来、赤外線吸収あるいは反射能を付与した繊維材料としては、いわゆる迷彩服が知られている。これは、戦場において赤外線による偵察から逃れるために、衣服の赤外線反射率を草木などの自然環境の赤外線反射率に近づける事を目的とし、赤外線波長領域において特定の赤外線吸収能を有する染料、顔料などにより迷彩模様を施したものである(特開平5−132879号公報)。迷彩服はその目的から衣服全面に迷彩模様を有することを必要としているため、風合いが損なわれ、高度の屈曲や伸縮、摩耗に耐えられないばかりでなく、通気性をも阻害するために衣料内の快適性が失われ、スポーツ衣料等に応用することは困難である。
【0005】
また、蓄熱性、保温性を得る目的で、炭化ジルコニウム等の赤外線を吸収する無機物を練り込んだ繊維製品(特開平3−3202号公報)や、また逆に太陽光を遮断し体温の上昇を防ぐ目的として、無機化合物を繊維中に練り込み、または含浸させた素材(特開平5−186942号公報)が開示されている。しかし、炭化ジルコニウム等及び無機化合物は、極めて固い物質であり繊維本来の風合いが損なわれ、また赤外線だけでなく可視光線をも吸収し濃色品しか得られないといった問題がある。
この様に従来技術は、赤外線による透視を防ぐことを目的としておらず、またそれら繊維材料の持つ性能を阻害しないように赤外線吸収能または反射能を付与した、満足できる繊維材料及び衣料は提案されていない。
【0006】
【発明が解決しようとする課題】
本発明は、繊維本来の風合い、性能を損なわず、衣料として使用する場合の意匠性にも影響することなく、赤外線透視撮影を阻止する事を目的とする繊維材料及び衣料を提供するものである。
【0007】
【課題を解決するための手段】
本発明は、赤外線吸収能または赤外線反射能を有する部分を表面積に対して40〜80%偏在させてなる赤外線による透視を防ぐ肌面当接用繊維材料、及び該繊維材料からなる衣料もしくは該繊維材料を部分的に有してなる衣料であり、好ましくはこの赤外線吸収能または赤外線反射能を裏面に有することを特徴とする衣料である。
繊維材料に赤外線吸収能または赤外線反射能を付与するには、近赤外線領域(780〜1500nm)の波長を吸収、又は反射する物質を繊維材料に固着させればよい。
【0008】
以下、近赤外線領域(780〜1500nm)の波長を吸収、又は反射する物質を赤外線遮断剤とする。また肌面当接用繊維材料を単に繊維材料と記載する。
用いられる繊維素材としては特に限定されず、植物繊維や動物繊維などの天然繊維、再生繊維、半合成繊維及び合成繊維などの化学繊維、並びにこれら天然繊維と化学繊維の混紡品、交織品、交編品などがある。
また繊維材料の形態も、織物、編物、不織布など特に限定されるものではない。
【0009】
赤外線遮断剤にはアントラキノン類、フタロシアニン化合物、ナフタロシアニン化合物、クロム、コバルト金属錯塩化合物、ジチオール系金属錯塩化合物、スクアリリウム化合物、イミニウム系化合物等の有機化合物や無機錯体、酸化イッテルビウム、リン酸イッテルビウム等のイッテルビウム化合物、酸化スズ、酸化インジウム等の無機化合物、またはそれらの混合物等があるが、繊維材料に付与した後の風合いなどを考慮すると有機化合物が好ましく用いられる。
また繊維に親和性のない赤外線遮断剤を使用する場合は、バインダー樹脂を使用して固着させる。親和性がある場合は、特にバインダー樹脂を用いる必要はない。
バインダー樹脂は、ポリエステル樹脂、アクリル樹脂、ウレタン樹脂など用いられる赤外線遮断剤との相溶性が良いものを使用すればよい。
【0010】
その固着の形状としては、繊維本来の風合い、性能を損なわないために繊維材料全面に固着させない模様、例えば点、線、格子などとし、赤外線遮断剤を偏在させることが重要であり、繊維材料の屈曲性、伸縮性を阻害しない形状にするのが望ましい。赤外線吸収又は反射能を有する部分とは赤外線遮断剤の固着部分を指しており、表面積に対するその固着部分の面積は40〜80%とする。固着部分の面積が80%以上になると、繊維の持つ織編組織の自由度を束縛し、繊維の風合いに影響を与え、また通気性を阻害することになる。逆に固着部分の面積が40%以下になると、赤外線を透過する面積が大きくなり透視阻止の効果が低減してしまう。この固着形状の例を図1に示す。また、赤外線吸収または反射能の付与は、衣料とした場合、その衣料全面に行う必要はなく、最終製品の形態を加味し、透視を阻止したい箇所にだけ付与させても良い。水着への付与例を図2に示す。
【0011】
赤外線遮断剤の固着の方法としては、繊維材料全面に固着させない方法が採用され、従来の捺染手法、例えばフラットスクリーンプリント法やロータリースクリーンプリント法,ローラープリント法等や、またグラビア法、インクジェット法などがある。
【0012】
この様に、繊維材料に赤外線吸収または反射能を偏在させることで、繊維本来の風合いや屈曲性、伸縮性を損なわず、特にスポーツ衣料に使用する場合、運動への妨げ、胸部や臀部において緊張感や圧迫感を与えずに、赤外線による透視を阻止することが可能となる。
また、赤外線吸収または反射能を有する繊維材料を一部または全面使用して衣料とした場合、赤外線遮断剤の固着面を衣料の表面、あるいは表面と裏面としても良いが、好ましくは裏面、つまり肌側とすることで、衣料の色彩、意匠性を損なうこともない。
【0013】
衣料としては、肌に直接触れて着用する、競技用及びファッション水着、マリンスポーツウェアー、体操着、レオタード、フィットネス着、スポーツウェアー、ゲームウェアー、ブラウス、ポロシャツ、Tシャツ、インナー等の薄地からなる衣料が例示でき、特に肌に密着して着用するものに対しての効果が顕著である。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a fiber material and a garment for skin contact, which have a performance to prevent fluoroscopy by absorbing or reflecting infrared rays with respect to a camera capable of night vision and fluoroscopic photography using infrared rays, and in particular, thin fabric materials such as sports clothing. The present invention relates to a textile material used for clothing that is worn in close contact with the skin and the clothing.
[0002]
[Prior art]
In recent years, with the widespread use of video cameras, a variety of functions have been added, and those capable of shooting in the dark, that is, night-vision shooting, have been put on the market.
The principle of night vision photography is as follows.
Currently, CCD lenses of video cameras that are widely used capture visible light, infrared light, and ultraviolet light, but the camera body has a built-in shield that absorbs infrared light and ultraviolet light, and this shield captures the CCD lens. The color and tone of the image are corrected, and the image close to nature is displayed in the viewfinder. By removing the built-in shield that absorbs infrared rays, infrared imaging is possible, and when a filter that cuts visible light is attached, information processing for color discrimination is simplified, and elementary particles in the dark By suppressing the phenomenon, night vision photography in the dark becomes possible.
A commercially available video camera capable of night-vision photography removes the above-described shield that absorbs infrared rays physically and electrically. In addition, a camera that does not have a night vision shooting function can be easily modified to a camera capable of night vision shooting.
[0003]
It has been found that if this night vision photographing function is used under conditions with a lot of infrared rays such as sunlight, it is also used for seeing through clothing. This is considered to be possible by infrared rays being transmitted straight through the clothing but reflected by the human skin and capturing the reflected infrared rays as an image of a human nude. In this way, the night-vision function can be used for inhumane acts by seeing through clothing that is in close contact with the skin, such as swimsuits, in addition to the purpose of night vision in the dark. ing.
[0004]
In order to prevent such see-through by infrared rays, the clothing absorbs or reflects infrared light having a wavelength of 780 to 1500 nm, which is used particularly for infrared photography, and does not allow infrared rays to reach the skin, or the infrared rays from the skin side are not worn. It may be possible not to go outside.
Conventionally, so-called camouflage clothing is known as a fiber material imparted with infrared absorption or reflectivity. The purpose of this is to bring the infrared reflectance of clothes close to the infrared reflectance of natural environments such as vegetation in order to escape from infrared reconnaissance on the battlefield. Thus, a camouflage pattern is applied (Japanese Patent Laid-Open No. 5-132879). Because camouflage clothing requires a camouflage pattern on the entire surface of the clothing for that purpose, the texture is impaired, not only can not withstand high bending, expansion and contraction, wear, but also in the clothing to inhibit breathability It is difficult to apply to sports clothing and the like.
[0005]
In addition, for the purpose of obtaining heat storage and heat retention, a fiber product (JP-A-3-3202) kneaded with an inorganic substance that absorbs infrared rays such as zirconium carbide, and conversely, the sunlight is blocked to increase the body temperature. For the purpose of prevention, a material (Japanese Patent Laid-Open No. 5-186842) in which an inorganic compound is kneaded or impregnated in a fiber is disclosed. However, zirconium carbide and the like and inorganic compounds are extremely hard substances and have a problem that the original texture of the fiber is impaired, and not only infrared rays but also visible rays are absorbed and only dark products can be obtained.
As described above, the prior art is not intended to prevent infrared fluoroscopy, and a satisfactory fiber material and garment to which infrared absorption ability or reflection ability is imparted so as not to impede the performance of the fiber material is proposed. Not.
[0006]
[Problems to be solved by the invention]
The present invention provides a fiber material and clothing intended to prevent infrared fluoroscopic photography without affecting the original texture and performance of the fiber and without affecting the design properties when used as clothing. .
[0007]
[Means for Solving the Problems]
The present invention relates to a fiber material for skin contact that prevents see-through by infrared rays, in which a portion having infrared absorbing ability or infrared reflecting ability is unevenly distributed in a surface area of 40 to 80%, and clothing or fiber comprising the fiber material It is a garment partially comprising a material, and preferably a garment characterized by having this infrared absorbing ability or infrared reflecting ability on the back surface.
In order to impart infrared absorbing ability or infrared reflecting ability to the fiber material, a substance that absorbs or reflects the wavelength in the near infrared region (780-1500 nm) may be fixed to the fiber material.
[0008]
Hereinafter, a substance that absorbs or reflects a wavelength in the near infrared region (780 to 1500 nm) is referred to as an infrared blocking agent. Further, the fiber material for skin surface contact is simply referred to as a fiber material.
The fiber material to be used is not particularly limited, and natural fibers such as plant fibers and animal fibers, regenerated fibers, semi-synthetic fibers and synthetic fibers such as synthetic fibers, and blends, interwoven products, There are knitted goods.
Further, the form of the fiber material is not particularly limited, such as a woven fabric, a knitted fabric, and a non-woven fabric.
[0009]
Infrared screening agents include organic compounds such as anthraquinones, phthalocyanine compounds, naphthalocyanine compounds, chromium, cobalt metal complex compounds, dithiol metal complex compounds, squarylium compounds, iminium compounds, inorganic complexes, ytterbium oxide, ytterbium phosphate, etc. There are inorganic compounds such as ytterbium compounds, tin oxides and indium oxides, or mixtures thereof, but organic compounds are preferably used in consideration of the texture after being applied to the fiber material.
Moreover, when using the infrared rays shielding agent which does not have affinity with a fiber, it fixes using a binder resin. When there is affinity, it is not necessary to use a binder resin.
As the binder resin, a resin having good compatibility with an infrared shielding agent used such as a polyester resin, an acrylic resin, or a urethane resin may be used.
[0010]
As the shape of the fixing, it is important to make the pattern not to be fixed to the entire surface of the fiber material in order not to impair the original texture and performance of the fiber, for example, a point, a line, a lattice, etc. It is desirable to have a shape that does not hinder flexibility and stretchability. The part having infrared absorption or reflectivity refers to the fixing part of the infrared shielding agent, and the area of the fixing part with respect to the surface area is 40 to 80%. When the area of the fixing portion is 80% or more, the degree of freedom of the woven or knitted structure of the fiber is restricted, the texture of the fiber is affected, and air permeability is hindered. On the other hand, when the area of the fixing portion is 40% or less, the area through which infrared rays are transmitted increases, and the effect of preventing see-through is reduced. An example of this fixed shape is shown in FIG. In addition, in the case of clothing, it is not necessary to impart infrared absorption or reflectivity to the entire surface of the clothing, and it may be imparted only to a location where it is desired to prevent fluoroscopy in consideration of the form of the final product. An example of application to a swimsuit is shown in FIG.
[0011]
As a method for fixing the infrared shielding agent, a method that does not fix the entire surface of the fiber material is adopted, and conventional printing methods such as flat screen printing method, rotary screen printing method, roller printing method, gravure method, ink jet method, etc. There is.
[0012]
In this way, the fiber material has uneven infrared absorption or reflectivity, so that the original texture, flexibility and stretchability of the fiber are not impaired. Especially when used for sports clothing, it impedes exercise and tension in the chest and hips. It is possible to prevent infrared fluoroscopy without giving a feeling of feeling or pressure.
In addition, when a part or the whole of a fiber material having infrared absorption or reflectivity is used as a garment, the fixing surface of the infrared shielding agent may be the surface of the garment, or the front and back surfaces. By setting it as the side, the color and design of clothing are not impaired.
[0013]
Apparel includes clothing made from thin fabrics such as competition and fashion swimsuits, marine sports wear, gym wear, leotards, fitness wear, sports wear, game wear, blouse, polo shirt, T-shirt, inner, etc. This is particularly effective for those that are worn in close contact with the skin.
[0014]
【Example】
Hereinafter, the present invention will be described in detail by way of examples.
[0015]
[Processing example 1]
Kyasorb IRG-002 (Imminium, manufactured by Nippon Kayaku Co., Ltd.) as an infrared absorber for knitted tricot fabric (weight per unit: 100 g / m 2 ) of polyester yarn (44 dtex / 36f) 80% and polyurethane yarn (44 dtex) 20% Water dispersion 0.1%, acrylic binder resin Primal HA-8 (made by Nippon Acrylic Chemical Co., Ltd.) 10.0%, and primal ASE-60 (made by Nippon Acrylic Chemical Co., Ltd.) 0.2% as a thickener The coating solution was coated on one side in a polka dot pattern with a gravure roll, and dried and fixed at a temperature of 130 ° C. for 2 minutes. In addition, the area ratio of the adhesion part in a coating part was changed to 0 to 100% (solid conversion adhesion amount: 0.1-1.8 g / m < 2 > versus cloth). The diameter of the polka dots was 3 mm or less. Further, the area ratio of 0% here means an unprocessed product, and the area ratio of 100% means that the entire surface is uniformly coated. (Figure 3)
[0016]
[Processing example 2]
Using the same fabric as in Processing Example 1, after dyeing light green by dip dyeing, 0.1% aqueous dispersion of Kayasorb IR-750 (anthraquinone, manufactured by Nippon Kayaku Co., Ltd.) as an infrared absorber, original paste (sodium alginate) A treatment solution of 60% and 10% urea was fixed on the surface after printing on one side by screen printing, followed by treatment with superheated steam at 170 ° C. for 2 minutes. Then, after the treated cloth was washed, a processed cloth was obtained. Note that the area ratio of the fixed portion was changed in the same manner as in Working Example 1.
[0017]
[Test Example 1]
Infrared transmittance measurement test About the work cloths of Working Examples 1 and 2, the infrared transmittance at a wavelength of 1000 nm was measured using a Hitachi spectrophotometer U-3410 equipped with an integrating sphere. With respect to the transmittance at a fixed part area ratio of 0% (unprocessed), the transmittance was less than half when the fixed part area ratio was 40% or more. The results are shown in FIG.
[0018]
[Test Example 2]
Infrared radiography test In order to confirm the actual fluoroscopy prevention effect, a video camera capable of infrared radiography was used. After creating a leotard wearing the work cloth of Processing Examples 1 and 2 with the fixing surface of the infrared absorber as the back surface, a woman wears it, and a Sony Corporation (product name: Handycam TRV9) video camera capable of infrared photography The photo was taken with the night vision function activated. The photographing was performed under sunlight with a large amount of infrared irradiation.
The criteria for this test are as follows.
◎: Not seen through at all ○: Blurred shadow is visible, but chest and flesh cannot be confirmed △: Breast and flesh can be confirmed, but difficult to see ×: See through
[Table 1]
Figure 0004080106
As shown in Table 1, it can be seen that the effect of preventing see-through is obtained at an area ratio of 40% or more.
[0020]
[Test Example 3]
Sensory evaluation In order to confirm the functionality of the garment of the present invention, a leotard was made with the processed fabrics of Processing Examples 1 and 2, and an actual wearing test was conducted by 10 women. The leotard dressing used in this test was produced only with a work cloth having a fixed partial area ratio of 40 to 100%, in which the effect of preventing fluoroscopy was obtained in Test Example 2 (infrared imaging test). Further, the fixing surface was arranged to be the back surface of the leotard.
The evaluation items and criteria for this test are as follows.
<Stretchability>
◎: good, ○: normal, △: somewhat difficult to move, ×: difficult to move <pressure>
◎: Not at all, ○: Normal, △: Some feeling of pressure, ×: Some feeling of pressure <sampling>
◎: Not at all, ○: Normal, △: Slightly steamed, ×: Steamed <Overall evaluation>
◎: Good without feeling uncomfortable, ○: Normal, △: Somewhat uncomfortable, ×: Uncomfortable strongly inappropriate
[Table 2]
Figure 0004080106
As shown in Table 2, the evaluation with a smaller fixed portion area ratio is high, and there is comfort. A 100% coated product is not suitable as clothing because the original performance and texture of the fiber are impaired.
[0022]
【The invention's effect】
Clothing that has infrared absorption or reflection ability unevenly distributed on the skin contact fiber material and has the fiber material over the entire surface or a part thereof does not impair the original texture, flexibility and stretchability of the fiber, and is used especially for sports clothing. In this case, it is possible to prevent the infrared fluoroscopy, which has become a social problem in recent years, without hindering exercise and giving a sense of tension or pressure in the chest or buttocks.
Further, by imparting infrared absorption or reflectivity to the back surface, that is, the skin side, it is possible to obtain clothing that does not impair the color and the design.
