Description
本発明は、本発明は主として衣料、帽子、手袋及び履き物などに加工される装身用品の原材料となる皮革に関する。 The present invention relates to leather which is a raw material of clothing accessories processed mainly into clothing, hats, gloves and footwear.
これまで、保温を目的とした衣料用等の布地や皮革加工原材料が各種提案され、提供されている。
それらは、いずれの皮革材においても、その強度的な性能は重要であるが、その上で、断熱性について優れ、且つ軽量化が可能な空気層を如何に効果的に確保するかが最大の課題となっている。
また布地では、例えば大量の空気層が形成され、しかも軽い羽毛を用いたダウンウェアが保温に優れた高級品として珍重されている。
また、毛付きの動物毛皮、発泡性人工皮革、繊維を起毛させた人工皮革なども、その繊維間に抱き込まれる空気によって断熱性を高め保温性の高い素材として各種用途に使用されている。
Up to now, various fabrics and leather processing raw materials for clothing and the like for heat insulation have been proposed and provided.
In any leather material, the strength performance is important, but the most important thing is how to effectively secure an air layer that is excellent in heat insulation and can be reduced in weight. It has become a challenge.
In fabrics, for example, a large amount of air layer is formed, and downwear using light feathers is prized as a luxury product with excellent heat retention.
In addition, animal fur with hair, foamed artificial leather, artificial leather with raised fibers, and the like are used in various applications as materials having high heat insulation and high heat retention by air entrapped between the fibers.
断熱性能を得るための空気自体は、熱伝導率が２０°Ｃで０．０２２ｋａｌ／ｍｈ°Ｃと小さいので優れた断熱性が得られメリットがある。
しかし、空気は気体であるので、身体の動きや体温によって、体積が小さくとも各空隙又は各気泡内に空気移動や循環が発生し、その結果、外気に接する気泡と肌側の気泡との間に温度連絡による熱交換が起こり、外気の影響が肌側に容易に達することになる。
この熱交換は、外気と肌面との温度差が大きいほど、空隙又は気泡内の空気移動や循環が活発化して、外気の温度が肌面に影響し易くなる。
The air itself for obtaining heat insulation performance has a merit that excellent heat insulation can be obtained because the thermal conductivity is as small as 0.022 kal / mh ° C. at 20 ° C.
However, since air is a gas, air movement or circulation occurs in each air gap or each bubble even if the volume is small due to body movement or body temperature. Heat exchange occurs due to temperature communication, and the influence of outside air easily reaches the skin side.
In this heat exchange, the larger the temperature difference between the outside air and the skin surface, the more the air movement and circulation in the voids or bubbles are activated, and the temperature of the outside air tends to affect the skin surface.
他方、例えば、人体では皮下脂肪があり、その皮下脂肪は分解されて熱エネルギーとなるとともにその存在自体の断熱・保温性能によって体温が効果的に保持されることが知られている。
そこで、例えば、その断熱・保温性能を活用して人工皮革にも脂肪を組み込もうとしても、その脂肪は温度が高くなると固形脂肪が液体脂肪となって人工皮革の組織内に溶け出してしまい、人工皮革に応用することには大変に困難である。
また、油脂類は短期間で分解し変質して、腐敗し悪臭を発するなどの難点がある。
このため、これまでそのようなことは提案されることも実施されることもなかった。
On the other hand, for example, it is known that there is subcutaneous fat in the human body, and the subcutaneous fat is decomposed to become heat energy, and the body temperature is effectively maintained by the heat insulation and heat retention performance of the existence itself.
So, for example, even if you try to incorporate fat into artificial leather by utilizing its heat insulation and heat retention performance, if the temperature rises, the solid fat becomes liquid fat and dissolves into the tissue of artificial leather It is very difficult to apply to artificial leather.
In addition, fats and oils are difficult to decompose and change in a short period of time, to rot and to produce a foul odor.
For this reason, this has never been proposed or implemented.
そこで、本発明者は、温度や紫外線などに対して物質安定性が高く、自由に変形できる柔軟性をもっている固体素材として、熱伝導率が小さく（０．０２〜０．０２ｋａｌ／ｍｈ°Ｃ程度）且つ熱保持性能（蓄熱性能）の高い物質、即ちシリコーン等のゲル材に着眼した。
ゲル材は元来変形しやすいので大変加工しにくく、また流動性の高いものでは大変扱い難いものと考えられているので、そのような、ゲル材を使用した人工皮革を提案する人はいなかった。
Therefore, the present inventor has a low thermal conductivity (about 0.02 to 0.02 kal / mh ° C.) as a solid material having high material stability with respect to temperature, ultraviolet rays, etc. and having flexibility to be freely deformed. ) And high heat retention performance (heat storage performance), that is, a gel material such as silicone.
Gel materials are inherently easy to deform, so they are very difficult to process, and those with high fluidity are considered to be very difficult to handle, so no one has proposed such artificial leather using gel materials. .
本発明は、このような実情に鑑みてなされたもので、物質安定性が高く、熱伝導率が小さく且つ気体や液体に較べると流動性が殆どなく、また熱保持性能に優れているゲル材を用いることによって、外気との熱交換が起こりにくく保温性・保冷性に優れた衣料などに加工される原材料としての皮革を提供するものである。 The present invention has been made in view of such circumstances, and is a gel material having high material stability, low thermal conductivity, almost no fluidity compared to gas and liquid, and excellent heat retention performance. By using, leather is provided as a raw material that is processed into clothing and the like that are less likely to exchange heat with the outside air and have excellent heat and cold insulation properties.
上記目的を達成するために、本発明は、人工合成皮革４を構成する皮革基材１中に玉状に形成した合成樹脂被膜５で被覆した高分子ゲル材２を含有させて成るゲル材含有皮革であって、
合成樹脂シートの上に玉状に高分子ゲル材２を散布し、その上から溶融合成樹脂を塗布又するか、又はその上に流して、散布した高分子ゲル材２をその溶融樹脂の被膜中に閉じ込めて、その樹脂の硬化を待ち、高分子ゲル材２を、その硬化した樹脂被膜で閉じ込め、さらにその上に溶融合成樹脂皮革基材１を塗布するか又はその上に流して高分子ゲル材２の層を製作し、
たらに、合成樹脂シートの上に前記高分子ゲル材２の散布と前記溶融合成樹脂の塗布又は上に流すことを交互に複数回繰返し、その都度硬化した樹脂被膜で高分子ゲル材２を閉じ込めて溶融合成樹脂皮革基材１を塗布するか又はその上に流して高分子ゲル材２の層を多層に製造したゲル材含有皮革である。
In order to achieve the above object, the present invention includes a gel material comprising a leather base material 1 constituting an artificial synthetic leather 4 and a polymer gel material 2 coated with a synthetic resin coating 5 formed in a ball shape. Leather ,
A polymer gel material 2 is sprayed onto a synthetic resin sheet in a ball shape, and a molten synthetic resin is applied or flown over it, and the polymer gel material 2 thus sprayed is coated with the molten resin. The polymer gel material 2 is confined with the cured resin coating, and the molten synthetic resin leather base material 1 is applied thereon or flown over the polymer gel material 2 while waiting for the resin to cure. Make a layer of gel material 2,
After that, the dispersion of the polymer gel material 2 on the synthetic resin sheet and the application of the molten synthetic resin or the flow over the resin are alternately repeated several times, and the polymer gel material 2 is confined with the cured resin coating each time. Then, the melt synthetic resin leather base material 1 is applied or poured onto the gel material-containing leather produced by multilayering the polymer gel material 2 layer .
また、人工合成皮革４を構成する皮革基材１中に玉状に形成した合成樹脂被膜５で被覆した高分子ゲル材２を含有させて成るゲル材含有皮革であって、
溶融合成樹脂皮革基材中１に玉状に形成した合成樹脂被膜５で被覆した高分子ゲル材２を投入して攪拌混合し、溶融状態で平面上に置くか又は半硬化状態で回転ロールによって、所望の厚さに形成してそのまま前記溶融合成樹脂皮革基材１を硬化させて製造したゲル材含有皮革である。
In addition, a gel material-containing leather comprising a polymer gel material 2 coated with a synthetic resin coating 5 formed in a ball shape in a leather base material 1 constituting an artificial synthetic leather 4,
A polymer gel material 2 coated with a synthetic resin coating 5 formed in a ball shape is put into a melt synthetic resin leather base material 1 and mixed by stirring, and placed on a flat surface in a molten state or by a rotating roll in a semi-cured state. The gel material-containing leather is produced by curing the molten synthetic resin leather base material 1 as it is to a desired thickness .
さらに、人工合成皮革４を構成する皮革基材１中に玉状に形成した合成樹脂被膜５で被覆した高分子ゲル材２を含有させて成るゲル材含有皮革であって、
合成樹脂繊維及び／又は無機繊維と合成樹脂バインダー繊維とからなる皮革基材1と、玉状に形成した合成樹脂被膜５で被覆した高分子ゲル材２とを攪拌混合し、加熱プレスして各繊維同士を結合させ、高分子ゲル材２入り不織布を形成して製造したゲル材含有皮革である。
Furthermore, a gel material-containing leather comprising a polymer base material 2 coated with a synthetic resin coating 5 formed into a ball shape in a leather base material 1 constituting an artificial synthetic leather 4 ,
A leather base material 1 composed of synthetic resin fibers and / or inorganic fibers and synthetic resin binder fibers and a polymer gel material 2 coated with a synthetic resin coating 5 formed into a ball shape are mixed with stirring, heated and pressed to each. This is a gel material-containing leather produced by bonding fibers together to form a nonwoven fabric containing a polymer gel material 2 .
本発明は上記構成であり、皮革基材１中に高分子ゲル材２が封入され、その高分子ゲル材２は、熱エネルギーは出し入れするが、気体に見られるような自由な物質循環・移動が殆どなく、そのため皮革内外への温度の移動、移転を容易にさせない作用を有する。このため、本発明皮革を加工した衣類などを着ると、肌から外気への温度放出が、高分子ゲル材２によって遮断され（断熱機能）、且つ、これまでの気泡（気体）による断熱作用と異なり、高分子ゲル材２内に伝熱された熱量が物質内部に保持され（蓄熱機能）、身体の皮下脂肪と同様に高い保温効果が得られる。それとは逆に、外部が熱くてもその熱さを遮断（断熱機能）し内部を保冷する効果もある。 The present invention has the above-described configuration, and the polymer gel material 2 is enclosed in the leather base material 1, and the polymer gel material 2 is free to circulate and move freely as seen in gas, although heat energy is taken in and out. Therefore, there is an action that does not facilitate the movement and transfer of temperature in and out of leather. For this reason, when a garment processed with the leather of the present invention is worn, the temperature release from the skin to the outside air is blocked by the polymer gel material 2 (heat insulation function), and the heat insulation action by the conventional bubbles (gas) In contrast, the amount of heat transferred into the polymer gel material 2 is held inside the substance (heat storage function), and a high heat retaining effect is obtained in the same manner as the subcutaneous fat of the body. On the contrary, even if the outside is hot, the heat is cut off (insulating function) and the inside is kept cool.
そして、冷たい水中にて使用されるウエットスーツや寒冷地の防寒着に使用すれば、寒冷環境に長時間耐えることができる。また、本発明の皮革を用いて、その他各種の高い保温性能が得られる保温用衣類や保温用の靴下、手袋なども製造が可能となる。
含有された前記高分子ゲル材２は合成樹脂被膜５で被覆されているので漏れ出すことはない。また、ゲル材含有皮革を裁断すると、裁断面から切られた合成樹脂被膜５内のゲル材は外に漏れ出るかもしれないが、その漏れ出る量はごく少量で済み、他のゲル材は漏れ出ることはない。
And if it is used for wet suits used in cold water and winter clothes in cold regions, it can withstand cold environments for a long time. In addition, by using the leather of the present invention, it is possible to manufacture other warming clothes, warming socks, gloves and the like that can obtain various other high heat retaining performances.
Since the contained polymer gel material 2 is covered with the synthetic resin film 5, it does not leak out. Moreover, when the gel material-containing leather is cut, the gel material in the synthetic resin film 5 cut from the cut surface may leak out, but the amount of the leak is very small, and other gel materials leak. Never leave.
さらに、前記高分子ゲル材２及び／又は皮革基材１中に、抗菌剤、芳香剤、消臭剤、着色剤、活性炭粉及び／又は粒子、セラミック粉及び／又は粒子、金属粉及び／又は粒子のうち少なくともいずれか１つの添加物を含有させることによって、かびや細菌の繁殖を防ぎ、芳しい香を発散し、体臭などを消臭し、また好みの色に着色し、電磁波を防ぎなどのそれら添加物Ａの特性を付与させることも可能である。 Further, in the polymer gel material 2 and / or the leather substrate 1, an antibacterial agent, fragrance, deodorant, colorant, activated carbon powder and / or particles, ceramic powder and / or particles, metal powder and / or By containing at least one additive among the particles, the growth of mold and bacteria is prevented, the fragrance is emitted, the body odor is deodorized, the favorite color is colored, the electromagnetic wave is prevented, etc. It is also possible to impart the characteristics of the additive A.

Is possible.
さらに、前記高分子ゲル材２及び／又は皮革基材１中に、抗菌剤、芳香剤、消臭剤、着色剤、活性炭粉及び／又は粒子、セラミック粉及び／又は粒子、金属粉及び／又は粒子のうち少なくともいずれか１つの添加物を含有させることもできる。 Furthermore, in the polymer gel material 2 and / or the leather substrate 1, an antibacterial agent, fragrance, deodorant, colorant, activated carbon powder and / or particles, ceramic powder and / or particles, metal powder and / or It is also possible to contain an additive of at least one of the particles.

Some of the manufacturing methods will be described below.
例えば、合成樹脂シートの上に高分子ゲル材２を散布し、その上から溶融合成樹脂を塗布又するか、又はその上に流して、散布した高分子ゲル材２をその溶融樹脂の被膜中に閉じ込めて、その樹脂の硬化を待ち、高分子ゲル材２を、その硬化した樹脂被膜で閉じ込め、さらにその上に溶融合成樹脂皮革基材を塗布するか又はその上に流して高分子ゲル材２が一層であるゲル材含有皮革が製作される。
高分子ゲル材２を多層とするには、例えば、前記高分子ゲル材２の散布と前記溶融合成樹脂の塗布を交互に複数回繰返し、その都度硬化した樹脂被膜で高分子ゲル材２を閉じ込めて溶融合成樹脂皮革基材を塗布するか又はその上に流してゲル材含有皮革を製作することも可能である。
For example, the polymer gel material 2 is sprayed on the synthetic resin sheet, and the molten synthetic resin is applied or flown over the polymer resin material 2 and then sprayed on the polymer resin material 2 in the film of the molten resin. The polymer gel material 2 is confined with the cured resin coating, and a molten synthetic resin leather base material is applied on or flown over the polymer gel material 2 A gel material-containing leather 2 is produced.

It is also possible to produce a gel material-containing leather by applying a molten synthetic resin leather base material or pouring it onto it.
また、溶融合成樹脂皮革基材中に玉状に形成した合成樹脂被膜５で被覆した高分子ゲル材２を投入して攪拌混合し、溶融状態で平面上に置くか又は半硬化状態で回転ロールによって、所望の厚さに形成してそのまま前記溶融合成樹脂皮革基材を硬化させて製造することが可能である。 In addition, the polymer gel material 2 coated with a synthetic resin coating 5 formed into a ball shape is put into a molten synthetic resin leather base material and mixed by stirring, and placed on a flat surface in a molten state or a rotating roll in a semi-cured state. Thus, it is possible to manufacture the molten synthetic resin leather base material as it is by forming it to a desired thickness.
さらに、合成樹脂繊維及び／又は無機繊維と合成樹脂バインダー繊維と、玉状に形成した合成樹脂被膜５で被覆した高分子ゲル材２とを攪拌混合し、加熱プレスして各繊維同士を結合させ、高分子ゲル材２入り不織布を形成することもできる。 Furthermore, the synthetic resin fiber and / or the inorganic fiber, the synthetic resin binder fiber, and the polymer gel material 2 covered with the synthetic resin coating 5 formed in the shape of a ball are stirred and mixed, and heated and pressed to bond the fibers together.
