Heat and moisture transport properties of multilayer menswear

The main aim of this study is to develop objective measurement method and design a unique measurement device, which simulates the relation between human body and multilayer menswear by taking into consideration air gap between cloth layers, and which is able to make measurement of heat and moisture transport between fabric layers and device skin. For this study the menswear sets were chosen from the market and structural properties of dress materials were determined. The heat transfer comfort properties of every dress materials were measured by Alambeta device and moisture comfort properties were measured by Permatest device in E.Ü. Textile and Apparel Research Application Center. However with those devices it is impossible to observe the heat transport, which is done by convection and moisture transport when it occurs by effect of air and wideness between wear layers. That's why to observe by simulation, heat and moisture transport between human body and apparel by taking into consideration wideness between cloth layers, as original side of this thesis was designed a measurement device. The device was developed by applying different experimental methods. Finally was developed a new experimental method and in continuous regime conditions was observed heat and moisture differences between microclimate and cloth layers. Designed device had been used to make experimental measurements of single and double layer fabric specimes that are taken from the menswear and the findings were compared analytically with the findings from Alambeta, Hot Plate and Permetest devices. Some of the findings were found highly correlated while some others were low correlated. Clothing suits were tested by thermal mannequin and there was observed small differences of little importance in clothing thermal resistance. However between thermal resistance off different types of tested fabrics was found significant differencies. Keywords: Menswear, Thermal and moisture comfort, Multilayer clothing, Device design
