Study of Fitting Models on Moisture Sorption Isotherms of Profiled Polyester Fabric

In this paper, the moisture sorption isotherms were measured of the profiled polyester (trefoil-shaped) fabric at different temperature and relative humidity, the influence of the temperature, relative humidity were summarized, and three kinds of commonly were used empirical models of moisture sorption comparing the fitting of experimental data, the suitable profiled polyester empirical model of equilibrium moisture content of fabric were identified. The results showed that with the increase of temperature, weave the equilibrium moisture content rate decreased slightly; with the increase of relative humidity, weave the equilibrium moisture content rate increased, and relative humidity than the temperature has greater effect; the model can agree well with the experimental data.
