Abstract:

In order to expand the research approaches of woven fabric design, evaluation and optimization of thermal comfort, a effective method to predict the thermal resistance of fabric was provided.The numerical simulation of heat transfer through fabric in one direction was investigated according to heat transfer theory and fabric?3D models, and the temperature distribution in dynamic heat transfer process was described. A geometric model of plain weave fabric was established based on geometrical structure parameters using microscopic image and slicing techniques . The fabric system was assembled by fabric model and still air model around the yarn. The boundary conditions and the interaction were set according to simulation condition and the numerical solution was calculated by the finite element analysis software ABAQUS.The constant temperature flat test simulating the skin heat lose was conducted to verify the validity of the heat transfer model, the results show that the outside surface temperature from simulations and experiments had a good consistency over the time, the error range between the theoretical thermal resistance and the experimental one is 3.9%, and the two results coincided very well.

Key words: fabric, geometric model, beat transfer, numerical simulation, thermal resistance
