In this paper, we compared the temperature and relative humidity changes for silk fabrics with polyester fabrics and got GM(1,P) relation models respectively between maximum fabric temperature change, maximum relative humidity change at outer still air layer and relative fabric character parameters. Furthermore, by comparing the objective experiments with subjective wear trials, it is found that the amounts of the change rate of fabric temperature and relative humidity at outer still layer are the most important factors which influence clothing comfort in dynamic moisture transfer condition. The more the changes of temperature and R.H., the more the mugginess and the thermal sensation.展开更多
