PURPOSE: Bedclothes are provided to improve the heat insulating property by filling foaming granules, based on polyolefin-based polypropylene resin and germanium powder, in a space between an upper cover and a lower cover. CONSTITUTION: An upper cover(102) and a lower cover(104) are sewn, and a space is placed between the upper cover and the lower cover. A polyolefin-based polypropylene resin and at least one functional material are mixed to form foaming granules in order to obtain a filler(106). The filler fills the space between the upper cover and the lower cover. The functional material is selected from germanium powder, scoria, and red-clay powder. |
