| 摘 要： | 由热量通过纺织品传递的基本规律入手 ,建立了描述热量通过纺织品传递的理论模型 ,利用有限元分析方法完成了相应的理论计算 ,并通过实验对理论分析结果进行验证。分析过程中针对纯棉织物 ,由织物外层表面温度及一定时间内总的热量损失等入手 ,从理论及实验 2个方面阐述了织物层数、人体与织物之间的空气层、织物间空气层在不同的环境温度下对热量传递的影响。

| Abstract: | Theoretical equations were given to describe heat transfer process through textile system on the basis of physical laws of heat transfer.Theoretical achievements were obtained using finite element method and verified by experimental test.Influence of fabric layers,air layer between human body and fabric,air layer between fabrics on heat transfer through textile system was studied by taking into account the outer|surface temperature and the total heat loss at a certain period of time. |

| Keywords: | layer surface temperature heat flux heat loss finite element |
