あった。[Problems to be Solved by the Invention] However, in the above-mentioned prior art, the temperature of the flowing air when spray coating the latent heat storage material with the resin for preventing dye bleeding is high enough to cause a phase transition of the latent heat storage material impregnated with the granules. This is often carried out at a temperature higher than that temperature, and as a result, the latent heat storage material melts and oozes out onto the surface of the granular material, resulting in poor adhesion of the oozing prevention resin to the surface of the granular material, making it difficult to prevent oozing from occurring properly. There was a problem in that film formation was inhibited.

樹脂の皮膜が形成できる。When spray coating the surface of a granular material impregnated with a latent heat storage material in flowing air to prevent the latent heat storage material from seeping out, the resin melted due to the temperature of the flowing air and oozed onto the surface of the granular material. The latent heat storage material is absorbed by the oil absorbing material mixed with the granules, making it easy for the oozing prevention resin to adhere to the surface of the granules, so the oozing prevention resin of the latent heat storage material adheres to the surface of the granules. This makes it easier to coat and form a good seepage-preventing resin film.
