Description of the Related Art Heat-retaining heat-generating fabrics that require heat retention and heat generation generally include a method of kneading ceramics into fibers, a method of adding ceramics (zirconium carbide, etc.) or a metal to a coating agent or a laminate resin, or the like. Various methods of keeping a heat by attaching a heating agent to fabric have been proposed.
For example, as a method of kneading ceramics or metal into fibers, a method of manufacturing a fiber product disclosed in JP-A-63-105107 or far-infrared radiation fibers for mites as described in JP-A-7-331584 may be used. There has been proposed a method of kneading ceramics and metal that emits light. However, these methods have drawbacks in that the strength of the raw yarn is reduced by kneading the ceramics and metal, and the ceramics and metal are colored. As a method of adding ceramics (zirconium carbide or the like) or metal to a coating agent or a laminating resin, see Japanese Patent Application Laid-Open No. Sho 60-1
No. 62641, a sheet material having an excellent heat retaining effect, a coated fabric disclosed in JP-A-63-35887,
No. 83579, such as cloth or paper products coated with ceramics. However, these are excellent as windproof materials because they impart a film to the cloth, but have the disadvantage that the feeling of the film remains on the cloth. A method of keeping a heat by adhering a heating agent to a fabric is disclosed in JP-A-62-187.
No. 782 and Japanese Patent Application Laid-Open No. 1-503632 disclose a method utilizing a thermal change at the time of a phase change of a substance. However, these methods involve complicated manufacturing steps,
Deterioration in performance and change in hand due to washing are disadvantages.
