摘　　要：为了改善防水透湿纳米纤维膜的热舒适性,提高人体穿着的舒适度,采用COMSOL仿真软件,通过有限元法对纳米纤维薄膜进行仿真模拟。仿真模拟计算了透气率和透湿率,最后模拟预测了不同温度下薄膜的透气率和透湿率。结果表明:薄膜透气率和透湿率会随着膜厚度的增加而降低。仿真预测了温度对透气率和透湿率的影响规律:随着模拟温度升高,透气性变差,透湿性变好。In order to improve the thermal comfort of waterproof and moisture permeable nanofibre film and enhance the comfort of human wearing,COMSOL simulation software is used to simulate the nanofibre film by the finite element method.The air permeability and moisture permeability are calculated in the simulation,and finally the air permeability and moisture permeability of the film at different temperatures are predicted.The results show that the air permeability and moisture permeability of the film decrease with the increase of the film thickness.The simulation predicts the law of the influence of the temperature on the air permeability and moisture permeability:the air permeability is getting worse and the moisture permeability is getting better with the increase of the simulated temperature.
