と全く異なるものである。A major feature of the linear body of the present invention is that it has a heat generating portion. Conventionally, organic fibers having infrared radiation are known, but they only emit infrared rays when heated from the outside, and are only used for passive or passive purposes such as heat retention. The linear body of the present invention generates heat when connected to a power source, and as a result emits infrared rays. In other words, the linear body of the present invention self-excited and actively emits infrared rays, and can not only keep warm but also actively heat bodies and objects, and can also freely adjust the intensity of infrared rays as necessary. They differ from conventional passive infrared emitters in that they can also be controlled and regulated.

In the present invention, far infrared rays have a wavelength of 4.5 to 80μ.
It refers to electromagnetic waves of 5 to 20 μm, and the region of 5 to 20 μm is particularly important. Therefore, it is preferable to use particles such as those described above that have a high radiation efficiency of infrared rays having a wavelength of 4.5 to 80 μm at a working temperature of, for example, 40 to 200°C. Taking the radiation ability of a black body as 100 (%), the radiation ability of a particle compared with it is called radiation efficiency (%). In particular, at a temperature (e.g. 40 to 50 degrees Celsius) that does not cause discomfort or burns even when in contact with the human body for a long time, and a wavelength of 4.5 to 4.5 degrees Celsius.
The average infrared radiation efficiency of particles in the 80 μm region is 60%.

(4) indicates a conductor. FIG. 1 shows an example of a concentric core-sheath composite filament, in which an energized heat generating part is the core, an infrared emitting layer is arranged in the sheath part surrounding it, and a covering layer is arranged in the frog outer layer. The electrically conductive heat generating portion of the core may be a metal wire or may be a conductive polymer mixed with a conductive filler.

することも出来る。In other words, if the infrared radiation layer containing many infrared radiation particles is exposed, it tends to cause severe wear and tear damage to the metals and guides of spinning machines, drawing machines, knitting machines, looms, etc. that come into contact with it. In order to prevent this, it is desirable to coat it with a polymer that does not contain or has a small content of abrasive particles. However, since the polymer of the coating layer absorbs infrared rays, the wavelength is 4 to 20 μm.
It is desirable to use a polymer (for example, polyethylene) that has low infrared absorption in this region, and to make the thickness as thin as possible, for example, 10 μm or less, particularly 5 μm or less. Similarly, the coating layer polymer can contain small amounts of infrared emitting particles, for example up to 10%, especially 0.5 to 6%, to enhance its infrared emitting capabilities. On the other hand, after producing a fibrous structure such as a 7M fabric using a linear infrared radiator having a coating layer (3), only the coating layer is dissolved or decomposed and removed to expose the infrared ray emitting layer and improve infrared radiation. You can also do that.

された。When comparing the heating properties of the legs of WHI and WH2, WHI felt warm from inside, while ■2 felt less warm from inside, and WHI was more comfortable. Similarly, a polyethylene bag filled with physiological saline and tofu was placed in place of the human body, and the internal temperature was measured after 15 minutes.
The temperature was 88°C when Swa 1 was used, and 29°C when Swa 2 was used, indicating that the internal heating capacity of WHI is high.

面は第８図のようなものである。Example 2 A mixture of 20 parts of polyamic acid obtained from pyromellitic anhydride and diaminodiphenyl ether, 80 parts of nickel particles with a particle size of 1.1 μm, and 100 parts of dimethylformamide (DMF) was mixed into a spun yarn of meta-aramid fiber (60 parts of dimethylformamide (DMF)). It was impregnated into a hand-paired yarn, dried, and heat-treated (260°C) to harden it. On top of that, 70 parts of polyamic acid, 80 parts of alumina particles with a particle size of 0.8 μm and an infrared emissivity of 80%, 1) MF80
After applying 0 parts of the mixture 8 times and drying at 60°C, further apply polyamic acid solution on the surface and dry it to form a linear heating element YH8.
