Abstract: This paper reports a new methodology for design of clothing to achieve thermal functional performance by application of numerical simulations. The method is based on the mathematical models developed to describe the processes of coupled heat and moisture transfer inside clothing and numerical simulation programs. With this method, the thermal functional performance of clothing can be designed from selection of textile fibers, garment fabrics as well as garment constructions. The main design processes consist of: 1) construct virtual clothing; 2) select textile materials; 3) carry out numerical simulation; and 4) critical analysis of thermal functional performance of the clothing. As an example, a two-layer clothing system with four designs of clothing constructions are simulated, three with different types of waterproof fabric are selected as outer layer versus one with open structure. By analyzing the result of the numerical simulation for the four designs, we find that garments with different waterproof fabric have significant difference in the dynamic distribution of temperature, water vapor concentration, water content in fiber and liquid water condensation in clothes, indicating their thermal functional performances are different. This example has shown that the numerical simulation can be an effective design tool for the thermal functional apparel products development.
