Fractal Polyester;Moisture Transfer;Model;Humidity Field
Abstract
The dynamic moisture absorption of fractal polyester was studied at a constant temperature (30 °C) and
humidity (80% RH). The model of heat and moisture transfer was then built based on the heat and
mass transfer theories. Finite element method was used to solve the model. By comparing the moisture
absorption predicted by the mechanism model and the experimental data, we concluded that variations
trend of both were consistent. Besides, fields of temperature and humidity with different thickness of
fractal polyester were predicted and analyzed by this model.
