Abstract:

To explore the influence of wind and body movement on clothing insulation, firstly, thermal convection between human body and environment was pointed out and the fact that wind and body movement have significant influence on clothing insulation was clarified based on theory analysis and existing research data. Then, the test methods of dynamic thermal is sulation, including human test and thermal manikin test, were summarized. Qualitative analysis of resultant insulation indicates that the thermal is sulation of clothing tends to decline under wind and body movement. Also, the influence of wind and body movement put on thermal resistance is weakened gradually with the increase of wind and body movement. Lastly, prediction models of dynamic insulation values were summarized according to different types of clothing. Future research on prediction model for clothing dynamic insulation will make breakthrough in optimizing the correction model and local dynamic insulation.
