Description of the Related Art Conventionally, there has been known a three-layer structure cloth in which a batting material is inserted between a front material and a backing for the purpose of improving heat retention in winter clothes and sports clothes. This is intended to improve heat retention by the thickness of the air layer in the batting material. However, if such a three-layer fabric is adopted as a material for winter clothes or sports clothes that require particularly easy movement, there is a problem that the clothes are heavy and bulky when worn, and free movement is hindered. Was.
In recent years, as a method for solving the above problem, vapor deposition of metal on a cloth has been performed. That is, by using the metal vapor deposition layer on the inside, the heat from the human body is reflected on the surface of the fabric to reduce the heat escaping to the outside of the fabric for heat retention. Therefore, there is a problem that the application is limited from the viewpoint of.

There is proposed a composite fiber (JP-A-5-331754) in which a thermoplastic polymer having a melting point and a crystallization temperature close to the body temperature or the outside air temperature is included in the fiber.

It has problems such as liquid seeping out. Further, the latter has a problem that the thermoplastic polymer exudes from the fiber end surface by the heat applied during the production process to the fabric even if the latter is included in the core portion as the core-sheath fiber.

Further, if the melting point is too lower than the ambient temperature, it is sufficient for melting, but the crystallization temperature is also lower than the vicinity of the melting point and the ambient temperature, so that the crystallization temperature cannot be used as latent heat. None of them can achieve the above-mentioned object of the present invention. Further, the temperature falling crystallization temperature is required to be 45 ° C. or lower, and more preferably within the above-mentioned application range for the above reason. Further, the heat of fusion and heat of crystallization of the organic compound are 20 mJ / m.

The cooling crystallization temperature of these organic compounds can be adjusted by containing a crystal nucleating agent, but the present invention is characterized in that the organic compound is supported on a porous body which is also a crystal nucleating agent and kneaded into the fiber. Therefore, the supercooling phenomenon can be prevented. In the present invention, it is important that the organic compound is contained in the fiber in a state of being retained by the porous body described later, but the content of only the organic compound is 1 to 30% by weight, preferably 2 It is preferably contained in the fiber in an amount of ˜20% by weight.

This porous body has an effect of holding the dissolved organic compound in the fiber and not exposing it to the surface of the fiber, and also has an effect of suppressing the heat loss rate during spinning to be small, and the particle size thereof is 0.01 to
A range of 1.0 μm, preferably 0.03 to 0.5 μm is suitable. If the particle size is smaller than 0.1 μm, agglomeration will occur during mixing, and if the particle size is larger than 1.0 μm, the nozzles will be clogged during spinning and the operability will be significantly impaired. The specific surface area of the porous body is 10 m 2 / g or more, preferably 50 m 2 / g or more. When it is 10 m 2 / g or less, the oil absorption is remarkably inferior, and when the organic compound melts, it is not retained by the porous body and appears on the surface, so that the heat resistance is inferior, and when it reaches the fiber surface, the feel is impaired.

When the mixing ratio is large, when the organic compound is melted, it is not completely absorbed by the porous body and is exposed on the fiber surface, impairing the feel of the fiber.
When the mixing ratio is small, the amount of organic compounds kneaded into the fiber is small, so it is preferable to increase the ratio as much as possible.
