満足できるものではなかった。However, although urethane foam used as a cushioning material has not only cushioning properties but also properties such as heat retention and heat insulation, in the end, it only performs this function. That is, although urethane foam configured as pine tresses and the like is used as a material for various articles that are frequently used on a daily basis, it does not have a positive effect on the human body. Therefore, in the past, the functionality of this type of urethane foam as a material was never satisfactory.
それ故、本発明はクツション材等として日常身辺に存在

である。(Means for Solving the Problems) The present invention focuses on the fact that far infrared rays exhibit various excellent characteristics in the medical field, etc., and utilizes the irradiation effect of far infrared rays to achieve the above objectives. This is what we aim to achieve.

が認められている。In other words, the effect that far infrared rays have on the human body has been attracting attention in recent years, but far infrared rays not only exert a thermal effect due to their unique wavelength as electromagnetic waves, but also dilate microvessels in the human body, promote blood circulation, It promotes the normal metabolism of human tissues by having various positive effects on human tissues, such as maintaining the water content of cell fibers, decomposing body wastes such as lactic acid, sterilizing, and activating other cells. It is recognized that it can be performed.

である。The gist of the structure of the present invention is a urethane foam that is mixed with a far-infrared ray emitting material that emits far-infrared rays.
また、上記ウレタンフオームを製造する方法の要旨は、
ウレタンフオームの原料に少なくとも界面活性剤と粉粒

発泡させる点にある。In addition, the gist of the method for manufacturing the above urethane foam is as follows:
The method consists of mixing at least a surfactant and a powdery far-infrared emitting material with the raw material of the urethane foam, and then foaming the raw material.

こととなる。(Function) Therefore, when the above-mentioned urethane foam is applied to cushioning materials such as pinerests, etc., the urethane foam can constantly irradiate the user's body with far-infrared rays, resulting in a thermal effect. In addition, it will promote blood circulation and normal metabolism of human body tissues.

フオームを製造できることとなる。In addition, in the above manufacturing method, since the urethane foam raw material is foamed with the powdered far-infrared emitting material mixed with the urethane foam raw material, the internal structure of the urethane foam inevitably changes. By interposing a far infrared ray emitting material therein, the far infrared ray emitting urethane foam according to the present invention can be manufactured.

線放射材料の混入量を増大できることとなる。Therefore, when mixing the urethane foam raw material and the far-infrared ray emitting material, the greater the ratio of the far-infrared ray emitting material to the urethane foam raw material, the more difficult it is to mix them uniformly due to the difference in specific gravity. This becomes a factor in the generation of cracks during foaming, but the surfactant added during the mixing lowers the interfacial tension of the urethane foam raw material liquid and produces a dispersion effect. As a result, a large amount of far-infrared emitting material can be uniformly mixed into the urethane foam raw material to prevent cranking in the foamed urethane foam, increasing the amount of far-infrared emitting material mixed into the urethane foam. It becomes possible.
（実施例）
以下、本発明の実施例について先ず製造方法の一例から
説明する。(Example) Examples of the present invention will be described below, starting with an example of a manufacturing method.
先ず、ポリウレタンの生成発泡原料の一例としては、ト
リレンジイソシアナート或いは多核ポリイソシアナート
等のポリイソシアナートと、ポリプロピレングリコール
等のポリオールとが適用される。First, as examples of foaming raw materials for producing polyurethane, polyisocyanates such as tolylene diisocyanate or polynuclear polyisocyanate, and polyols such as polypropylene glycol are used.

。Further, as far-infrared emitting material, for example, alumina 50
%, and ceramics containing 30% silica (by weight) are applied, but this far infrared emitting material has a particle size of 30%, for example.
It is a powder formed in units of several micrometers, such as micrometers.

びポリオールに対して均一な状態に混合される。Next, when foam molding urethane foam, polyisocyanate and polyol are mixed with the far-infrared emitting material, water as a foaming agent and a surfactant such as silicone are added to these, and these are molded. Stir and mix in the machine. The surfactant lowers the interfacial tension of the polyisocyanate and polyol to improve dispersibility,
As a result, the far-infrared emitting material is uniformly mixed with the polyisocyanate and polyol.

である。In addition, as a result of this mixing, the polyisocyanate and polyol react to form polyurethane, and at the same time, gas is generated due to the reaction between the isocyanate group and water and the polyurethane is foamed. The urethane foam produced through these steps uniformly contains powdered far-infrared emitting material throughout its interior.

クが発生しないことが確認できた。In addition, in the above manufacturing process, when polyurethane is manufactured without adding a surfactant, the mixing ratio of the foaming raw material for polyurethane and the far-infrared emitting material is too:10 (
However, when the surfactant was added, the distribution density of the far-infrared emitting material became partially large and cracks occurred in some parts of the urethane foam. It was confirmed that cracks did not occur as long as the ratio did not exceed 100,720.

ツション材として好適な使用が行える。The soft urethane foam produced as described above has a far-infrared emitting material mixed throughout its interior, but since this far-infrared emitting material is a fine powder of about 3 μm, its flexibility is low. Elasticity 1: Can be suitably used as a cushion material without impairing elasticity.
また、上記ウレタンフオームから放射される遠赤外線の
人体に対する影響を試験した処、次の様な結果が得られ
た。Furthermore, when we tested the effects of far infrared rays emitted from the urethane foam on the human body, we obtained the following results.

右側に比してかなり高温に加温されている（緑、黄、赤
色に変化するに従って高温である）。In other words, each of the reference photos in the attached sheet is a thermovision photo that displays the temperature distribution and height difference on the surface of the object to be measured in color, but first of all, in the state of the first photo, the temperatures of both hands of the same person are almost the same. However, the left hand was then brought into contact with the far-infrared emitting urethane foam according to the present invention obtained by the above manufacturing method, and the right hand was brought into contact with a general urethane foam containing no far-infrared emitting material for 10 minutes each. As a result, as shown in the second photo, the left side irradiated with far-infrared rays is heated to a considerably higher temperature than the right side that is not irradiated (the temperature increases as the color changes from green to yellow to red).
尚、右側の温度が上昇したのはウレタンフオームの保温
性によるものである。The temperature increase on the right side is due to the heat retention properties of the urethane foam.
この様に、遠赤外線放射材料を混入したウレタンフオー

遠赤外線放射による加温作用が加味されて、その温熱効
果が倍増されるのである。In this way, in the case of urethane foam mixed with a far-infrared radiation material, the heating effect of far-infrared radiation is added to the heat-retaining property that the urethane foam itself inherently has, and its thermal effect is doubled.

に適用した場合にも当然得られるものである。In addition, the far infrared rays irradiated from the far infrared emitting material mixed in the urethane foam exhibit the above-mentioned thermal effect, but when this is applied to cushion materials such as pine tresses or sofas, the pine tresses, etc. Far-infrared rays can be naturally irradiated to the user at all times, and the thermal effect can relieve coldness and the like. Further, such effects can naturally be obtained not only when applied to cushion materials but also when applied to other wall materials, floor materials, etc.

ｍの波長範囲の遠赤外線に於いて顕著となるのである。Furthermore, far infrared rays penetrate not only the surface of the human body but also deep inside the human body tissue, expanding the microvessels of the human body tissue and promoting blood circulation, relieving stiffness in the shoulders and lower back, and further strengthening the tissue structure. In addition to maintaining water content and activating cells to promote metabolism, it also promotes the decomposition of internal wastes such as lactic acid.
Promotes recovery from fatigue. In particular, such an effect is 0.76μ
4 to 20 μm of infrared light in the wavelength range of m to 1000 μm
This is noticeable in far infrared rays in the wavelength range of m.
