Abstract
Description
【０００１】
【発明の属する技術分野】
本発明は、上着を着用した場合でも顕著な暖房効果が得られ、かつ、実質的な風合いの悪化の少ない光発熱性肌着に関する。
【０００２】
【従来の技術】
従来、繊維製品の保温性を高める方法としては、生地を厚くする、目を細かくする等の方法で生地の断熱性を高め、内部の熱を逃さないようにする方法が一般的であった。また、繊維の内部を中空にして空気の層を形成させることにより体温が外に逃げるのを防ぐ繊維製品も開発されている。これらの方法は、いずれも着用時に体温が外部に逃げるのを防ぐことによる保温効果を利用するものであり、得られる保温性は充分なものではなかった。
【０００３】
これに対して、一方、太陽光を吸収し熱に変えて着衣内部に放散させることで蓄熱性を得ようとする方法が試みられている。地球上に到達する太陽光の放射エネルギーの分布は０．５μｍのいわゆる近赤外線付近にピークがあり、０．３ 〜２．０μｍの波長領域内に全エネルギー量の９５％が集中していることから、近紫外線を熱エネルギーとして効率的に活用できるような光発熱性繊維製品を用いれば、衣類に暖房機能を付与することができる。
【０００４】
このような光発熱性繊維製品としては、例えば、炭化ジルコニウム等の近赤外線を吸収し熱に変換する無機物質を練り込んだ繊維製品が提案されている。また、特許文献１、２には、アミノ系化合物からなる赤外線吸収色素をバインダー樹脂を用いて繊維の表面に付着させた繊維製品が、特許文献３にはインダスレン染料をポリアミド繊維に付着させた繊維製品が開示されている。
【０００５】
光発熱性繊維製品を用いて衣類に暖房効果を付与する場合、最も効率よく暖房効果が体感されるのは、肌に直接接する肌着として用いる場合である。しかしながら、肌着上にシャツ等の上着を着用した場合、透過性に劣る近赤外線が肌着にまで達するエネルギー量が減少し、充分な暖房効果を得ることができない。これを補うために大量の近赤外線を吸収し熱に変換する物質を配合しようとしても、炭化ジルコニウム等の無機物質を練り込んだり、赤外線吸収色素を付着させたりすると生地の風合いが悪化し肌触りが悪くなることから、一定量以上を配合すると肌着としては用いることができなくなるという問題があった。

【発明が解決しようとする課題】
本発明は、上記現状に鑑み、上着を着用した場合でも顕著な暖房効果が得られ、かつ、実質的な風合いの悪化の少ない光発熱性肌着を提供することを目的とするものである。
【０００８】
【課題を解決するための手段】
本発明は、近赤外線を吸収し熱に変換する物質を含有する光発熱性肌着であって、前記近赤外線を吸収し熱に変換する物質は、肌に接する側の面よりも肌に接しない側の面により多く含有されている光発熱性肌着である。
以下に本発明を詳述する。
【０００９】
本発明の光発熱性肌着は、近赤外線を吸収し熱に変換する物質を含有する。
上記近赤外線を吸収し熱に変換する物質としては特に限定されないが、例えば、炭化ジルコニウム、酸化スズ及び金属錯体化合物からなる群より選択される少なくとも１種が好適に用いられる。上記金属錯体化合物としては、例えば、アンチモン固溶酸化スズ、炭化ハフニウム、アンソラキノン系化合物、ナフタロシアニン化合物等が挙げられる。
【００１０】
本発明の光発熱性肌着に用いる繊維生地材料としては特に限定されず、天然繊維、半合成繊維、合成繊維等のいずれの繊維でもよい。上記天然繊維としては特に限定されず、例えば、綿、麻、亜麻、羊毛、絹等が挙げられる。上記半合成繊維としては特に限定されず、例えば、レーヨン、ポリノジック、テンセル等が挙げられる。上記合成繊維としては特に限定されず、例えば、ナイロン等のポリアミド系、ポリエステル系、ポリオレフィン系、ポリウレタン系等の繊維が挙げられる。これらは、それぞれ単独で用いられてもよいし、混紡又は混織されて用いられてもよい。
【００１１】
上記近赤外線を吸収し熱に変換する物質は、肌に接する側の面よりも肌に接しない側の面により多く含有される。これにより、上着を着用することにより肌着に到達する近赤外線のエネルギー量が減少しても、上記近赤外線を吸収し熱に変換する物質の多くが外側にあることから、効率的に熱に変換して優れた暖房効果を発現することができる。一方、肌に接する側の面の含有量を抑えることにより、実質的な肌着の風合いの悪化を最小限に抑えることができる。
【００１２】
上記近赤外線を吸収し熱に変換する物質を上記繊維生地に含有させる方法としては特に限定されず、例えば、上記近赤外線を吸収し熱に変換する物質を適当なバインダー物質を含有する水溶液中に懸濁し、この懸濁液中に繊維生地を浸漬した後、乾燥、熱処理を行うことにより固定する方法等が挙げられる。
【００１３】
本発明の光発熱性肌着を製造する方法としては特に限定されないが、例えば、繊維生地に水分を含浸させる工程１と、水分を含有させた繊維生地を、絞り率２０〜２００％に絞って過剰な水分を除去する工程２と、過剰な水分を除去した繊維生地の一方の面を、近赤外線を吸収し熱に変換する物質がバインダー物質を含有する水溶液中に懸濁した懸濁液中に接触させた後、絞り率４０〜３００％に絞る工程３と、近赤外線を吸収し熱に変換する物質が付着した繊維生地を乾燥及び熱処理する工程４とを有する方法等が好適である。
【００１４】
上記方法では、工程１において繊維生地に水分を含浸させた後、工程２において絞り率２０〜２００％に絞って過剰な水分を除去する。好ましくは、絞り率８０〜１２０％に絞って過剰な水分を除去する。この段階で繊維生地は水分をある程度含有している状態にある。
次いで、工程３において、過剰な水分を除去した繊維生地の一方の面を、上記近赤外線を吸収し熱に変換する物質をバインダー物質を含有する水溶液中に懸濁させた懸濁液中に接触させた後、絞り率４０〜３００％に絞る。ここで、繊維生地は水分をある程度含有している状態にあったことから、懸濁液に接触させても急速に近赤外線を吸収し熱に変換する物質を吸い上げることがなく、絞り率４０〜３００％に絞れば、一方の面にのみ重点的に近赤外線を吸収し熱に変換する物質を付着させることができる。好ましくは、絞り率８０〜１６０％に絞る。
なお、本明細書において絞り率とは、繊維生地の重量に対する繊維生地に付着している液体の重量の割合を意味し、例えば、絞り率１００％とは、繊維生地１００ｇに対して１００ｇの液体が付着している状態を意味する。
【００１５】
上記繊維生地に付着させる近赤外線を吸収し熱に変換する物質の量は、上記懸濁液中の近赤外線を吸収し熱に変換する物質の濃度、及び、繊維生地を上記懸濁液に接触させる時間により調整することができる。上記懸濁液中における近赤外線を吸収し熱に変換する物質の濃度としては特に限定されないが、５ｇ／Ｌ以上であることが好ましい。５ｇ／Ｌ未満であると、必要な量の近赤外線を吸収し熱に変換する物質を繊維生地に付着させることができないことがある。上記繊維生地を上記懸濁液に接触させる時間としては上記懸濁液中における近赤外線を吸収し熱に変換する物質の濃度により適宜決定されるものであるが、１０秒以下であることが好ましい。１０秒を超えると、上記懸濁液に接触させた側とは反対の面にまで上記懸濁液が浸透し、一方の面に重点的に近赤外線を吸収し熱に変換する物質を付着させることができないことがある。
また、上記バインダー物質としては特に限定されず、例えば、通常綿に用いられるシリコン系バインダー等が挙げられる。
最後に、工程４において乾燥及び熱処理を行い、近赤外線を吸収し熱に変換する物質を繊維生地に固定する。
【００１６】
このようにして得た一方の面にのみ重点的に近赤外線を吸収し熱に変換する物質を含有する繊維生地を用い、近赤外線を吸収し熱に変換する物質を重点的に含有する側の面が肌に接しない側になるようにして、通常の方法により縫製することにより本発明の光発熱性肌着を作製することができる。
このような本発明の光発熱性肌着を製造する方法もまた、本発明の１つである。
【００１７】
本発明の光発熱性肌着は、肌に接しない側の面に近赤外線を吸収し熱に変換する物質を重点的に含有することにより、上着を着用することにより肌着に到達する近赤外線のエネルギー量が減少しても、効率的に熱に変換して優れた暖房効果を発現することができ、かつ、肌に接する側の面の含有量を抑えられることから実質的な風合いの悪化を最小限に抑えることができる。
【００１８】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a light-heat-generating undergarment capable of obtaining a remarkable heating effect even when wearing an outerwear and having substantially no deterioration in texture.
[0002]
[Prior art]
Conventionally, as a method of improving the heat retaining property of a textile product, a method of increasing the heat insulating property of the cloth by, for example, increasing the thickness of the cloth or making the eyes finer so as to prevent the internal heat from being released. Also, a fiber product has been developed in which the inside of the fiber is hollowed to form an air layer to prevent body temperature from escaping to the outside. All of these methods utilize the heat retention effect by preventing body temperature from escaping to the outside during wearing, and the obtained heat retention is not sufficient.
[0003]
On the other hand, on the other hand, there has been attempted a method of absorbing heat, converting the heat into heat, and dispersing the heat into clothes to obtain heat storage. The distribution of radiant energy of sunlight reaching the earth has a peak near the so-called near-infrared ray of 0.5 μm, and 95% of the total energy is concentrated in the wavelength range of 0.3 to 2.0 μm. Therefore, if a light-generating fiber product that can efficiently utilize near-ultraviolet light as heat energy is used, a clothing can have a heating function.
[0004]
As such a light-generating fiber product, for example, a fiber product in which an inorganic substance such as zirconium carbide that absorbs near infrared rays and converts the heat into heat has been proposed. Patent Documents 1 and 2 disclose a fiber product in which an infrared absorbing dye composed of an amino compound is attached to the surface of a fiber using a binder resin. Patent Document 3 discloses that an indathrene dye is attached to a polyamide fiber. A textile product is disclosed.
[0005]
When a heating effect is imparted to clothing using a light-generating fiber product, the heating effect is most efficiently experienced when it is used as an undergarment that directly contacts the skin. However, when an outerwear such as a shirt is worn on the underwear, the amount of energy that near infrared rays having poor transmittance reach the underwear is reduced, and a sufficient heating effect cannot be obtained. To compensate for this, even if you try to mix a substance that absorbs a large amount of near-infrared rays and converts it to heat, kneading inorganic substances such as zirconium carbide or attaching infrared-absorbing dyes will deteriorate the texture of the fabric and make it feel soft. There is a problem that if it is added in a certain amount or more, it cannot be used as an undergarment.
[0006]
[Patent Document 1] JP-A-8-003870 [Patent Document 2] JP-A-9-255890 [Patent Document 3] JP-A-11-131376
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and has an object to provide a light-heat-generating undergarment capable of obtaining a remarkable heating effect even when wearing an outerwear and having substantially no deterioration in texture.
[0008]
[Means for Solving the Problems]
The present invention is a photothermal undergarment containing a substance that absorbs near-infrared rays and converts it into heat, wherein the substance that absorbs near-infrared rays and converts it into heat is less in contact with the skin than the surface in contact with the skin. It is a light-generating underwear that is more contained in the side surface.
Hereinafter, the present invention will be described in detail.
[0009]
The photothermal undergarment of the present invention contains a substance that absorbs near-infrared rays and converts it into heat.
The substance that absorbs near infrared rays and converts it into heat is not particularly limited. For example, at least one selected from the group consisting of zirconium carbide, tin oxide, and a metal complex compound is preferably used. Examples of the metal complex compound include tin oxide dissolved in antimony, hafnium carbide, ansoraquinone-based compound, and naphthalocyanine compound.
[0010]
The fibrous fabric material used for the photothermal undergarment of the present invention is not particularly limited, and may be any fiber such as a natural fiber, a semi-synthetic fiber, and a synthetic fiber. The natural fiber is not particularly limited, and examples thereof include cotton, hemp, flax, wool, and silk. The semi-synthetic fiber is not particularly limited, and examples thereof include rayon, polynosic, and Tencel. The synthetic fiber is not particularly limited, and examples thereof include polyamide-based fibers such as nylon, polyester-based, polyolefin-based, and polyurethane-based fibers. These may be used alone, respectively, or may be used by blending or blending.
[0011]
The substance that absorbs the near-infrared ray and converts it into heat is contained more in the surface that is not in contact with the skin than in the surface that is in contact with the skin. Thereby, even if the amount of near-infrared energy that reaches the underwear by wearing the outerwear decreases, since most of the substances that absorb the near-infrared rays and convert them to heat are on the outside, the heat is efficiently converted to heat. By converting, a superior heating effect can be exhibited. On the other hand, by suppressing the content of the surface in contact with the skin, it is possible to minimize the substantial deterioration of the texture of the underwear.
[0012]
The method of causing the fiber cloth to contain the substance that absorbs near infrared rays and converts the heat into heat is not particularly limited.For example, the substance that absorbs near infrared rays and converts the heat into heat is contained in an aqueous solution containing a suitable binder substance. A method of suspending and immersing the fiber cloth in the suspension, followed by drying and heat treatment to fix the cloth is used.
[0013]
The method for producing the light-generating undergarment of the present invention is not particularly limited. For example, Step 1 of impregnating the fiber cloth with water and the step of squeezing the water-containing fiber cloth to a squeezing ratio of 20 to 200% are performed. Step 2 of removing the excessive moisture and placing one surface of the fiber fabric from which excess moisture has been removed in a suspension in which a substance that absorbs near infrared rays and converts it into heat is suspended in an aqueous solution containing a binder substance. A method including a step 3 of reducing the drawing rate to 40 to 300% after the contact and a step 4 of drying and heat-treating the fibrous cloth to which the substance that absorbs near infrared rays and converts it into heat is preferably used.
[0014]
In the above method, after the fiber cloth is impregnated with moisture in step 1, excess moisture is removed by squeezing in step 2 to a squeezing ratio of 20 to 200%. Preferably, the excess water is removed by squeezing to a squeezing ratio of 80 to 120%. At this stage, the fiber fabric is in a state of containing some water.
Next, in step 3, one surface of the fiber cloth from which excess water has been removed is brought into contact with a suspension in which the substance that absorbs near infrared rays and converts it into heat is suspended in an aqueous solution containing a binder substance. After that, the squeezing rate is reduced to 40 to 300%. Here, since the fiber dough contained a certain amount of water, even if it comes in contact with the suspension, it does not rapidly absorb near infrared rays and convert it into heat even when it comes into contact with the suspension. If it is reduced to 300%, a substance that absorbs near infrared rays and converts it into heat can be attached to only one surface. Preferably, the aperture ratio is reduced to 80 to 160%.
In addition, in this specification, the squeezing rate means the ratio of the weight of the liquid adhering to the fiber cloth to the weight of the fiber cloth. For example, 100% of the squeezing rate means 100 g of the liquid for 100 g of the fiber cloth. Means the state where is adhered.
[0015]
The amount of the substance that absorbs near-infrared light and converts it into heat, which is attached to the fiber cloth, is the concentration of the substance that absorbs near-infrared light and converts it into heat in the suspension, and the fiber cloth comes into contact with the suspension. It can be adjusted depending on the time to be performed. The concentration of the substance that absorbs near infrared rays and converts it into heat in the suspension is not particularly limited, but is preferably 5 g / L or more. If it is less than 5 g / L, a substance that absorbs a necessary amount of near-infrared ray and converts it into heat may not be able to adhere to the fiber cloth. The time for bringing the fiber cloth into contact with the suspension is appropriately determined by the concentration of a substance that absorbs near infrared rays and converts it into heat in the suspension, but is preferably 10 seconds or less. . If the time exceeds 10 seconds, the suspension penetrates to the surface opposite to the side contacted with the suspension, and a substance that absorbs near infrared rays and converts it into heat is attached to one surface. You may not be able to do it.
The binder material is not particularly limited, and includes, for example, a silicon-based binder that is usually used for cotton.
Finally, in step 4, drying and heat treatment are performed, and a substance that absorbs near infrared rays and converts it into heat is fixed to the fiber cloth.
[0016]
Using the fiber fabric containing a substance that absorbs near infrared rays and converts it to heat only on one side obtained in this way, the side that mainly contains a substance that absorbs near infrared rays and converts it to heat The light-generating undergarment of the present invention can be produced by sewing the surface so that the surface is not in contact with the skin by an ordinary method.
Such a method for producing the photothermal undergarment of the present invention is also one of the present invention.
[0017]
The light-generating underwear of the present invention, by mainly containing a substance that absorbs near-infrared light and converts it into heat on the side not in contact with the skin, is a near-infrared ray that reaches the underwear by wearing the outerwear. Even if the amount of energy is reduced, it can be efficiently converted to heat to achieve an excellent heating effect, and since the content of the surface in contact with the skin can be suppressed, substantial deterioration of the texture can be achieved. Can be minimized.
[0018]
【Example】
Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples.
[0019]
(Example 1)
The 100% cotton knitted fabric was immersed in water and squeezed with a padder at a squeezing ratio of 80%. One surface of the dough is brought into contact with a suspension in which 0.5% of tin oxide fine particles are suspended in an aqueous solution containing 1% of a binder (Vinetex S200L: manufactured by Daiwa Chemical Industry Co., Ltd.) for 0.5 seconds. Immediately after that, it was squeezed using a padder at a squeezing rate of 100%. Thereafter, the fabric was dried at 100 ° C. for 5 minutes, and further subjected to a heat treatment at 140 ° C. for 3 minutes to produce a light-heat-generating underwear cloth.
[0020]
(Comparative Example 1)
The 100% cotton knitted fabric is immersed in a suspension in which 0.5% of tin oxide fine particles are suspended in an aqueous solution containing 1% of a binder (Vinetex S200L: manufactured by Daiwa Chemical Industry Co., Ltd.). After drying at 5 ° C. for 5 minutes, heat treatment was further performed at 140 ° C. for 3 minutes to prepare a light-heating underwear cloth.
[0021]
(Comparative Example 2)
As a raw material, 100% cotton knitted fabric was used after bleaching.
[0022]
The following evaluation was performed on the cloth for underwear obtained in Example 1 and Comparative Examples 1 and 2.
[0023]
(1) Evaluation of Tin Oxide Adhesion Amount on Fabric The surface of the fabric (the surface treated with tin oxide) and the back surface (the tin oxide was not acted on) were measured for the amount of Sn element using a fluorescent X-ray analyzer. ) And the amount of tin oxide adhering to the entire dough was measured.
The results are shown in Table 1.
[0024]
[Table 1]
(2) Evaluation of Light Heating Function The fabric was turned upside down, and a shirt made of 50% white cotton and 50% polyester was put on the cloth. A 500 W reflex lamp was placed at a position at which the distance from the fabric was 50 cm, and light was irradiated over the shirt so that the fabric temperature was about 40 ° C. or less (sunlight level in autumn and winter). The light was turned off 10 minutes after the start of irradiation, and the temperature of the dough was measured by a temperature sensor attached to the back of the dough until 20 minutes later.
The temperature change during this time is shown in FIG.
[0026]
From Table 1, it can be seen that the light-emitting fabric obtained in Example 1 and the light-emitting fabric obtained in Comparative Example 1 had almost the same amount of tin oxide as a whole, but Comparative Example 1 did not. Although the amount was almost the same on both the front surface (the surface where tin oxide was applied) and the back surface (the surface where no tin oxide was applied), in Example 1, more tin oxide adhered to the front surface than the rear surface. Was.
Also, from FIG. 1, the light-emitting fabrics obtained in Example 1 and Comparative Example 1 both had a higher dough temperature than the untreated fabric, but in particular the light-emitting fabric obtained in Example 1 A heating effect higher than that of the light-emitting fabric obtained in Comparative Example 1 was obtained.
[0027]
