Clothing and duvet covers for stimulating and promoting blood circulation are also known (Japanese Utility Model Publication Nos. 61-91237 and 61-180045).

射量が低く、その効果も多くは期待できない。By the way, the former health clothing using the far infrared rays is to heat the ceramics at the human body temperature and to radiate the far infrared rays from this, but the temperature range in which the body temperature can be heated, that is, 40 In the temperature range of ℃ or less, the far infrared radiation amount is low, and its effect cannot be expected much.

い。On the other hand, when the artificial electret is used, the amount of electricity necessary for exhibiting a desired action cannot be obtained, and thus a sufficient effect cannot be expected. That is, there is usually a voltage of several tens of mV, the so-called skin potential, between the front and back surfaces of human skin, but in order to have some effect on this skin potential, at least 10 -10 esu in CGS units is required. Energy is needed. However, the polarization charge that can be generated in the conventional artificial electret material is 0.2 to 0.7 eV, that is, 3.2 × 10
Since it is only about −13 to 2.24 × 10 −12 CGS · erg, it has practically no effect on the skin potential.

The charge amount rapidly declines as the temperature rises, and most of the charge amount disappears in the vicinity of 70 to 80 ° C., so that there is a drawback that processing and processing requiring high temperature cannot be performed. Therefore, the spinning dope itself which has been melted by heating cannot be electretized, and the electretized fiber product cannot be dry-cleaned or ironed.

3 ) 3 Si 6 O 18 (O, H, F) 4 ] (where X is Mg, Fe or Li) is a natural mineral with a polarization charge of 2 to 10 eV (3.2 × 10 -12 CGS.erg ~ 1.6 × 10 -11 CGS
erg) and the piezoelectric coefficient is (normal temperature) 5.8 × 10 -8 CGS ・ esu ~ 1.
1 × 10 -7 CGS.esu has been observed.

ている。Pure tourmaline was used as a gem, and now it is also possible to artificially synthesize crystals.
In the present invention, this artificial crystal tourmaline is also included. And tourmaline is a substance that shows electrical characteristics as an electret and has permanent spontaneous electric polarization.
Does not change the polarization vector under the influence of an external electric field. Further, tourmaline shows the strongest electret property among minerals, and a very remarkable far-infrared radiation amount is recognized.
このトルマリンは、粒径２μｍ以下の微粒子に粉砕して
用いることが必要である。これよりも大きい粒径のもの
は、エレクトレットとしての性能を十分に発揮できない
上に、繊維の手触り感がそこなわれ、製品に加工したと
き、品質の劣化を免れない。This tourmaline needs to be used after being crushed into fine particles having a particle size of 2 μm or less. If the particle size is larger than this, the performance as an electret cannot be sufficiently exhibited, and the feel of the fiber is impaired, and the quality is inevitable when processed into a product.
本発明においては、このトルマリン微粒子を、繊維に対

消すおそれがある。In the present invention, it is necessary to fix or contain the tourmaline fine particles in a proportion of 3 to 4% by weight with respect to the fibers. If the amount of this tourmaline is less than this, it will not be possible to give a sufficient stimulation to the skin potential, and if the amount of tourmaline is more than this, the charge between adjacent tourmalines will act to give an apparent charge. May be canceled.
このトルマリン微粒子を繊維に固着させるには、例えば

接着剤を用い、硬化剤により硬化させることによって行
うこともできる。To fix the tourmaline fine particles to the fiber, for example, to an acrylic emulsion as an adhesive, a necessary amount of tourmaline fine particles is mixed in a cross-linking aid, if necessary, and the mixture is applied to the fiber at a predetermined temperature. Heat to cure. It is also possible to use a urethane adhesive instead of this acrylic emulsion and cure it with a curing agent.

ものとなる。Further, in the present invention, when an organic fiber that is used to form a yarn using a spinning dope is selected, the tourmaline fine particles may be directly dispersed in the spinning dope to form an electret fiber. it can. In this case, since the tourmaline is contained inside the fiber, the amount of tourmaline peeled off is extremely small as compared with the case where the fibers are fixed.

れる。Moreover, since the mineral electret mixed in the spinning dope melted at a high temperature exhibits extremely high electret properties, the yarn formed from this spinning dope exhibits an extremely high electric potential. In the formed fiber product, not only the amount of charge is not attenuated by cleaning or the like, but also a high potential can be obtained again by high temperature drying or ironing. Therefore, unlike the conventional artificial electret in which a synthetic resin such as polypropylene is electretized by corona charging, friction treatment, or the like, the inconvenience of being unable to be normally handled with heat treatment is solved.

衝撃が与えられたとき、高次の電流が発生し、皮膚電位
に影響を与えるのに十分な電界を生じる。Action As described above, tourmaline exhibits extremely high polarization charge and piezoelectricity as compared with conventional artificial electrets.Therefore, when fibers containing this are used, when a shock is given due to contact between fibers or other causes, Current is generated, producing an electric field sufficient to affect the skin potential.

のである。The skin potential of the human body is usually several tens of mV, but it is known that this voltage is not constant and fluctuates due to changes in physical condition and exercise amount. In particular, the membrane potential of a cell depends on the osmotic pressure due to the difference in ion concentration between substances inside and outside the cell and the Na
It refers to the potential difference generated inside and outside the cell by active transport by a pump, and the cell membrane potential of nerves and muscles has been observed to be about 50-80 mV. This membrane potential disappears when the cell membrane dies, and on the other hand, when the cell is activated or the cell membrane is stimulated, an active potential is generated in the cell membrane. Then, the excitement of the cell membrane due to this action potential is fed back to the central nerve to regulate the independent nervous system and the motor nervous system.

気的刺激を与えることで、細胞膜の膜電位を活性化させ

が予想され、新陳代謝や血行の循環を促進させるもので
ある。Therefore, the skin potential decreased due to fatigue and aging is externally electrically stimulated to activate the membrane potential of the cell membrane. As a result, it is expected that feedback from the central nervous system is promoted, which promotes metabolism and circulation of blood circulation.
一方、トルマリンは、遠赤外線の放射が認められてい

遠赤外線との相乗効果により、細胞組織を刺激し、この
刺激が細胞膜の膜電位を活性化させ、新陳代謝や血行の
循環を促進させるものである。On the other hand, tourmaline emits far infrared rays. That is, this tourmaline radiates far infrared rays to the skin while applying an electrical stimulus to the skin. However, this radiation amount is weak in a temperature range around body temperature, but it is a sufficient amount to reach the skin from the skin surface to the new skin. Therefore, on the skin surface,
At the same time as giving the above-mentioned electrical stimulus, it emits far-infrared rays, so the polarization charge of tourmaline and piezoelectric power,
By a synergistic effect with far-infrared rays, it stimulates cell tissues, and this stimulation activates the membrane potential of cell membranes, promoting metabolism and circulation of blood circulation.
さらに、トルマリンは、熱するほど高い分極電荷を示
し、かつ、その圧電率も高くなるという、極めて熱に強
い性質がある。そこで、高温で溶融された紡糸原液内に
混入したトルマリンは、極めて高いエレクトレット特性
を示す。Furthermore, tourmaline has an extremely heat-resistant property that it shows a higher polarization charge as it heats up, and its piezoelectric coefficient becomes higher. Therefore, tourmaline mixed in the spinning dope melted at a high temperature exhibits extremely high electret characteristics.
