Outline of Final Research Achievements

In this study, an attempt to design comfortable clothing based on the optimization of clothing ventilation was examined. First, to gain an understanding of the physical phenomena of the formation of clothing ventilation, heat transfer and flow analyses were conducted using multi-point temperature and humidity measurements and the PIV method. Because clothing is of course for humans, its usability was evaluated using a motion capture system for human dynamics, and the overall wearer’s comfort evaluation method was established. As an example for practical clothing applications, a prototype was prepared, and its effect on clothing ventilation and comfort was verified using subjects. A design methodology for comfortable clothing based on the optimization of clothing ventilation was developed.

Academic Significance and Societal Importance of the Research Achievements

被服は着衣者の人体温熱状態や快適性に大きな影響を持ち，また着衣・着装を変化させることで即効性をもってこの微空間を着衣者好みに創り上げることができる．一方で衣服気候形成に関わる物理的メカニズムは非常に複雑現状の被服設計は経験則や被験者評価に基づくものも多く，換気の工夫が快適被服設計に生かされていない．本研究では，快適被服設計を実現するために，換気による物理的な衣服気候形成の理解にとどまらず，被服素材特性，人体の形態や動作，生理機能と被服・外環境の関係性を理解し，また同時に被服機能に関する物理を被服構成に反映する被服学の知見など横断的に整理を行い，機能的な被服を提案可能とした．
