服装织物层热湿传递机理模型

MECHANISM MODEL ON HEAT AND MOISTURE TRANSFER IN FABRIC

以服装的织物层为考察对象,基于织物层内部的多孔介质特点,依据表征性体积单元的概念,应用连续介质的分析方法,考虑织物层热湿传递过程中的相变、吸湿、解吸等作用,以及质量、动量、能量三大守恒定律,建立了能够反映织物层温度场、湿分浓度场及气相总压场变化规律的三场机制模型。

A new theoretical model which could be used to derive the distribution of temperature, moisture and total press in fabrics is proposed in this thesis. The classical conservation theories of mass, energy and momentum are combined with the geometrical, physical features of fibers, yarns, and fabrics in order to get the mathematical descriptions of the transport phenomena in a volume unit including phasechange, absorption/ desorption processes etc.
