摘要

A nonlinear convection equation is present for coupled heat and moisture transfer of fabric, emphasizing on the influence of local thermal equilibrium. state, the physical properties of boundary condition, fiber type of sandwich material. By using the Crank-Nicolson method to analyze the conservation equations, explore the process of coupled heat and moisture for multi-layer fabric to determine the influence of property of batting. Selected polyester and viscose as experimental batting, comparing the results of simulation, changes trend of polyester is faster in the, same time stability is relatively poor, so viscose batting is better in heat and moisture comfort.
