초록

This study measured the effect 3D printing products comprised of different materials and shapes on heat trans-fer in clothing to derive fundamental data on thermal comfort among clothing comfort. The variables were three typesof material (EVA foam, TPU-10%, TPU-10%+EVA), two types of shape (without holes, with holes), and two types of cov-ers(without cover, with cover). All samples (12 types) prepared by combining these variables were placed on the hot plateset at 36oC, and the surface temperature was measured at three points for 10 minutes. The surface temperature changewas dependent on the material, shape, and cover of the sample. The sample printed with TPU exhibited higher tem-perature transfer compared to the EVA foam sample after 10 mins. In addition, the temperature transfer was better whenthere were holes, and rate decreased when the sample was covered with fabric. We confirmed that material selection ofthe pad and thermal conductivity of the cover are extremely important in solving thermal stress to the human body causedby functional clothing with protectors. Additionally, as the protector, it is recommended to design the outer shell with apassage, such as a hole, to allow the rapid transfer of heat to the external environment.
