Abstract:

Research of numerical simulation of heat and moisture transfer can provide theoretical foundation for the preparation and heat-moisture peoperties evaluation of porous textiles. Based on the heat and moisture transfer through fabrics fabrics was summarized in terms of heat and moisture transfer models, numerical simulation  methods and test methods of fabric heat-moisture transport properties, and the problems existing in the numerical simulation of heat and moisture transfer in fabric were analyzed. Taking into consideration interweave structure characteristics of fabric and the physical properties of the yarn was proposed when coupled geat and moisture transfer model established in three-dimensionl. In addition, the change of material physicalproperties depending on practical application conditions was considered in the process of numerical analysis, heat and moisture transfer numerical model of fabric need further optimize and the improvement of the accuracy.

Key words: fabric, heat and moisture transfer, numerical simulation, heat and moisture coupling
