The design development of a ventilated T-shirt

Thermal comfort is the key issue to be considered when designing a garment. To improve the ventilation of a garment, some designers tend to use functional fabric such as moisture management material, while other may think any possibilities to create certain ventilated details to strengthen this function. To achieve this purpose, putting vents or openings on the garment is one of the popular ways. However, there are few researches explaining how much of this kind of design can contribute to the body ventilation. Too, limited researches have been done to investigate further product development related to this topic. In this study, a ventilated T-shirt is designed. To evaluate its function on body ventilation, a series of experiments are conducted in chamber. During the testing, a sweating manikin named Walter is used to simulate both walking and standing postures of a real person. The testing results provide evidence to show how much this new design can contribute to better heat and moisture transfer between body and ambient environment.
