Abstract

Water vapor transfer through a fabric, and subsequently a layered clothing system, directly affects the human body's thermal comfort. Clothing systems are essentially a way of layering clothes together to ensure comfort during outdoor activities. The aim of this study was to investigate the behavior of a clothing system's water vapor transfer to determine a comfortable clothing system combination for outdoor activities. A water vapor transfer rate (WVTR) of 12 three-layer combinations of 100% wool and Coolmax fabrics as the base layer, two polyester fleece fabrics as the mid layer, and three waterproof breathable fabrics as the outer layer was tested. Our results show that when the clothing system was applied, it worked together as a whole with the layers having some noticeable influence on each other; it should be noted that every layer offered varying WVTR degrees. The WVTR of a clothing system is mainly related to the type of waterproof, breathable fabrics used for the outer layer. Therefore, a comparison of the WVTR of the outer layer to the clothing system shows that the exact same trend is followed. The WVTR of the clothing systems is significantly correlated with fabric treatments such as finishes, coatings, and film membranes that are added to the outer layer fabrics.
