ている。2. Description of the Related Art Conventionally, various heat storage members having heat storage properties have been used for clothes worn in an environment where temperature changes are remarkable. Such a member having heat storage properties is generally obtained by spinning a synthetic resin containing a microcapsule containing a microcapsule in which a substance having a melting point around room temperature is applied and fixed to a cloth. There are known fabrics made of woven fibers, that is, fabrics.

る。However, in the case where the conventional microcapsules are applied and fixed on a cloth,
An adhesive is required to fix the microcapsules to the cloth. This adhesive must be used in a large amount in order to exhibit sufficient heat storage and durability, and there is a problem that the texture of the cloth after being applied becomes hard.

し、衣服として良好に機能しないおそれがある。[0004] Further, for example, in order to enhance comfort when wearing clothes, moisture permeability, moisture absorption / release properties, water resistance, and the like are required in addition to heat retention. However, when the microcapsules are applied and fixed on a cloth or the like with an adhesive, the heat retention is improved, but the moisture permeability of the cloth is reduced by the binder, and the cloth may not function well.

れがある。On the other hand, microcapsules are formed in a certain size in terms of structure. As a result, in the case where a fiber obtained by spinning a synthetic resin containing microcapsules is used as a fabric, the particle diameter of the microcapsules is larger than the fiber diameter. For this reason, there is a possibility that cutting, that is, thread breakage may occur during the spinning step or the weaving step into the cloth.
