が知られている。2. Description of the Related Art One use of fabrics, that is, woven fabrics, knitted fabrics, non-woven fabrics and the like, has heat storage properties (heat retention, cold retention).
Is. As a new attempt to improve the heat storage property, metal is vapor-deposited on a cloth. That is, by using the metal vapor deposition layer on the inside, heat from the human body is reflected on the surface of the fabric to reduce the heat that escapes to the outside to obtain heat retention, while using the metal vapor deposition layer on the outside. In this way, the heat from the sun is reflected on the surface of the cloth, and the heat entering the cloth is reduced, thereby obtaining cold insulation. Oxide ceramics are known as particles that effectively radiate far infrared rays.Coating resin containing ceramics to improve heat retention can be applied to knitted or woven fabrics, or the ceramics can be used as a spinning solution directly or in advance as a solvent. A method is known in which they are dispersed and dispersed and then mixed and spun.

If this concentration is less than 5% by weight, the concentration of the stock solution for spinning is lowered, the spinnability is lowered, and the physical properties of the fiber are lowered. On the other hand, when it exceeds 40% by weight, not only is it difficult to uniformly disperse the heat storage agent (C) due to the increase in viscosity, but also the spinnability is lowered and it becomes difficult to manufacture it industrially easily.
