中文摘要：

为了研究添加相变微胶囊织物的热特性，基于织物热湿耦合模型，本文发展了一个新的数学模型。模型考虑了多种相变微胶囊与织物的热传递，纤维的吸湿性／放湿性以及热湿耦合作用。模型方程采用控制体积法进行了求解。数值解与实验结果进行了对比，表明了该模型具有满意精度。模拟了相变材料总合量相同，但相变材料布置方式不同的织物在加热过程中的热特性。结果表明，相变微胶囊及其混合物在织物中的布置方式不同，对织物热特性有重要影响。

英文摘要：

To investigate thermal properties of the textile with phase change material （PCM） microcapsules, a new mathematical model is developed based on the coupled heat and moisture transfer model. The heat exchange among the multi-type PCM microcapsules and the textile, the moisture sorption/desorption by the fiber and the interaction between the heat and the moisture are considered in the model. And the governing equations are solved by using the control volume method. Meanwhile, the theoretical predictions are compared with experimental data. The result indicates that the model is satisfactory. Also, the thermal properties of textiles with different PCM distributions and the same PCM total content are simulated. The conclusion shows that the distribution of the PCM microcapsules and their mixture in the textile influences the thermal properties of the textile.
