っている。(Conventional technology) It is a type of electromagnetic wave (far infrared rays with wavelengths longer than 2 rays have little absorption attenuation by air, and the human body, which is made up of proteins, fats, carbohydrates, and a large amount of water, is a good absorber of far infrared rays. In addition, far-infrared rays are said to have a deeper penetration power than short-wavelength near-infrared rays, and have properties such as giving a mellow i!lS, and have recently been actively applied to health and medical fields. ing.

が今一つ充分ではない。Oxide ceramics are known as particles that effectively emit far-infrared rays, but ceramics also have excellent heat resistance, and far-infrared heaters and far-infrared cookers are commercialized today. . As for the application of far-infrared rays to fibers, attempts have been made to coat a single object with a resin containing ceramics to increase heat retention, but although such resin treatment is effective in terms of heat retention, it does not damage the fiber itself. It has the disadvantage of having a poor texture. Furthermore, for example, Japanese Patent Application Laid-Open No. 63-42970 proposes a method of impregnating ceramic powder into yarn made of natural or chemical fibers as an improvement in resin processing. However, the texture and softness were not completely improved, and there were also problems with washing resistance due to post-processing. Also, JP-A-63-1524
Although the publication proposes a composite fiber using a powder having far-infrared radiation n·1 characteristics, the far-infrared radiation effect is not quite sufficient.

μm, more preferably 0.4 to 0.7. If the average particle size of the fine powder is less than 0.3 μm, agglomeration tends to occur, making it difficult to achieve uniform fine dispersion even using a dispersion device, and
If it exceeds 10 μm, even if a uniform dispersion state is obtained, it is not preferable for the purpose of the present invention considering the fiber performance.
