Test and Evaluationof Thermal Performance of Thermotherapy Textiles and Research Progress of Heat Transfer Mechanism Thereof

From the perspectives of practical application, efficacy evaluation, use safety and thermal comfort of thermotherapy textiles, the research, application and development status of wearable products with functions of hot compress, thermal therapy and other health effects are overviewed. Firstly, thermal therapy products are classified into two types: electric heating and infrared heating, and analysis is made on the current methods of thermal performance test and curative effect evaluation of thermal therapy textiles, andthe impact of different experimental methods on thermal performance prediction are expounded from the advantages and disadvantages of human thermal physiological experiments and animal experiments respectively. Secondly, based on the study of the heat transfer mechanism of wearable thermotherapy textiles, the research status of skin heat transfer model and textile heat transfer model was elaborated, and the application of finite element simulation in human skin tissue and textile heat transfer research was overviewed. Finally, it is pointed out that it should be done to fully and accurately simulate the heat transfer system of human skin and textiles, and establish the evaluation criteria on thermal comfort and treatment safety of wearable thermotherapy textiles.
