［産業上の利用分野］
本発明は、遠赤外線放射体、特に遠赤外線放射性のフオ
ームに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to far-infrared emitters, particularly far-infrared emissive foams.
［従来の技術］
近年、遠赤外線放射性のセラミックスを利用した種々の
発熱体が知られている。これらの発熱体の使用態様は、
構造上の見地から次の三種に大別できる。[Prior Art] In recent years, various heating elements using far-infrared emitting ceramics have been known. The usage of these heating elements is as follows:
From a structural standpoint, they can be broadly classified into the following three types.
■セラミックス粉末を、そのままあるいは任意の形状に
焼成等により成型して使用する（特公昭４７−２５０１
０号、特開昭、６１−２１７１１２号）。■ Ceramic powder is used as it is or after being molded into any shape by firing etc. (Special Publication No. 47-2501
No. 0, JP-A-Sho, No. 61-217112).
■セラミツクス粉末を、樹脂板、繊維、織物等の基質表
面上に、樹脂、接着剤等でコーティングして使用する（
特開昭５９−２３２５６０号、特開昭６０−２３９５４
３号、特開昭６１−２２７３８９号）。■ Ceramics powder is used by coating the surface of substrates such as resin plates, fibers, and textiles with resin, adhesive, etc. (
JP-A-59-232560, JP-A-60-23954
No. 3, Japanese Patent Publication No. 61-227389).
■セラミツクス粉末を、繊維実質内に保有させて使用す
る（特開昭６１−１２９０８号）。(2) Ceramic powder is used by being held within the fiber substance (Japanese Patent Application Laid-Open No. 12908/1983).
しかしながら、前記■のごとくセラミックス粉末を焼成

態様に自ずと限界がある。例えば、特開昭６１−２１７

がある。また、■の繊維内部にセラミックス粉末を含有

号からも明らかなように、セラミックス粉末を染色原料
相当に微粉化しなければ紡糸できない。また仮に微粉化
しても、多量の充填は前記同様の曳糸性の観点から制限
があるので、充填量が少なく、十分な発熱効果が期待で
きない。このため、用途も著しく制限される。However, when ceramic powder is fired and molded into tablets or scales as described in (2) above, there are limits to how it can be handled and used. For example, JP-A-61-217
When used in bedding as in No. 112, even if a plurality of tablet-shaped heating elements are placed at arbitrary locations on the futon, a uniform planar heating element cannot be obtained. On the other hand, the ceramic powder coated on a substrate such as fiber or fabric (■)
Although the above-mentioned problem (2) can be solved as a planar heating element, it has the fatal disadvantage of impairing the air quality of the fibers or fabric itself, and there is a risk of peeling when repeatedly bent. In addition, in the case of containing ceramic powder inside the fibers described in (1), the above-mentioned problems of (2) and (2) are solved, but in order to incorporate the ceramic powder into thin fibers, it is necessary to
As is clear from the issue, spinning is not possible unless the ceramic powder is pulverized into a powder equivalent to the raw material for dyeing. Furthermore, even if it is pulverized, filling a large amount is limited from the viewpoint of spinnability as described above, so the amount of filling is small and a sufficient heat generating effect cannot be expected. Therefore, the applications are also significantly limited.
［発明が解決しようとする問題点］
本発明は、前記のごとき問題点を解決した取扱性に優れ

ームを提供することを目的としている。[Problems to be Solved by the Invention] An object of the present invention is to provide a porous far-infrared emitting foam that solves the above-mentioned problems and is easy to handle and has good heat-generating and heat-retaining properties.

％の範囲が実用的である。The far-infrared emitting ceramic powder used in the present invention is mainly made of a mixture of metal oxides such as titanium, zirconium, manganese, nickel, cobalt, lithium, magnesium, calcium, iron, and zinc, silicic acid, and alumina. Zirconia ceramics, titanium ceramics, magnesia ceramics, and other far-infrared emitting ceramics can be used. In particular, when the far-infrared emitting foam of the present invention is used for heat retention by contacting a living body, it emits electromagnetic waves with a peak wavelength of 4 to 50 microns when heated to a temperature close to body temperature, for example, 30 to 37 degrees Celsius. It is desirable to use zirconia-based ceramics that emit radiation. Although it is preferable that the particle size of the ceramic powder be fine, the physical properties of the foam itself will not be impaired even if it is not made as fine as the dyeing raw material as in the case of filling it into fibers. The amount of ceramic powder to be filled cannot be specified because it varies depending on the purpose of use of the foam, but it is approximately 5 to 80
% range is practical.

When foamed, a porous far-infrared emitting foam is obtained in which the ceramic powder is contained within a resin substance forming a three-dimensional network.
充填量にもよるが、セラミックス粉末は、樹脂実質内部
に略連続した筋状に均一に保有される。Although it depends on the filling amount, the ceramic powder is held uniformly in a substantially continuous streak inside the resin substance.

In addition to the warming effect based on this exothermic action, it is presumed that the synergistic effect with the heat insulation and heat retention effect of the foam itself provides an excellent heat retention effect that is different from that of simple textiles, depending on the application.
