Abstract

Heat transfer in clothing can be influenced by posture change of the human body and garment pattern design. In this study, the volume of the air gaps and the contact area were investigated for different arm postures of a thermal manikin using a three-dimensional body scanner, and the effect of garment pattern design was analyzed. Furthermore, the local thermal insulation of different body parts of the thermal manikin was tested for six kinds of arm postures when the manikin was dressed in various experimental garments. Both arm postures and garment styles had a strong effect on the local air gap distributions. The air gap volume decreased, and the contact area increased with the growth of protraction angles of arms. The human tests also indicated that the range of arm motion was improved, and better flexibility was perceived compared with the original style. A significant positive correlation between thermal insulation and air gap volume (r = 0.753, p < 0.001) was found.

手臂姿势和服装风格对局部活动和隔热的影响
人体姿势的变化和服装图案的设计会影响服装的传热。本研究利用三维人体扫描仪对热人体模型不同手臂姿势下的气隙体积和接触面积进行了研究,并分析了服装图案设计的影响。此外,在人体穿着不同实验服装时,测试了人体不同部位在六种手臂姿势下的局部绝热性能。手臂姿势和服装风格都对局部气隙分布有很强的影响。随着臂伸角的增大,气隙体积减小,接触面积增大。人体测试还表明,手臂的运动范围得到了改善,与原来的风格相比,人们感觉到了更好的灵活性。保温隔热与气隙体积呈显著正相关(r = 0.753, p < 0.001)。
