织物热湿传递测评及模型研究进展

织物热湿传递性能是影响着装舒适性的重要因素。为指导舒适性面料的开发,需准确测试织物热湿传递性能,明确织物热湿传递机制。因此,文中介绍了稳态条件下织物热传递和湿传递的测试装置及方法,动态条件下常温环境、冷环境及两种环境交换的织物热湿传递测试装置及方法,综述了织物热湿传递的稳态模型和动态模型的发展历程及现有不足。基于目前的研究现状,从测评方法及数学模型两方面对未来研究方向提出展望,即搭建多种环境及运动状态下的织物微气候测评系统,基于微观尺度建立三维织物热湿传递动态模型。

Research Progress of the Heat and Moisture Performance Evaluation and Modeling of Fabrics

The heat and moisture transfer performance of the fabric plays an important role in the clothing comfort. In order to guide the development of comfortable fabrics, it is necessary to accurately measure the heat and moisture transfer performance of the fabric and explicit the heat and moisture transfer mechanism, which were therefore introduced in terms of the measuring devices and methods of heat and moisture transfer in the steady-state condition, as well as the normal temperature environment, the thermal environment and two switching environment in the dynamic-state condition. And the research status and existing shortcomings of the steady model and dynamic model of the heat and moisture transfer were analyzed as well. Based on the current research status, the future research direction was proposed from two aspects including the measurement method and model construction, which was to build the microclimate assessment system of the fabric in various environments and motion states, and to establish the dynamic model of the thermal and moisture transfer of three-dimensional fabric based on the microscale.
