Abstract
The moisture adsorption process of fabrics is investigated theoretically and experimentally, as the first step for clarifying the whole process of the dimensional changes due to the moisture adsorption and desorption.
Assuming that the fabric is a flat plate of the homogeneous continuum, the moisture adsorption process of fabrics is calculated by applying a set of equations for moisture adsorption.
In the experiment, the adsorption process of serge and tropical fabrics are examined in which blending ratios of wool, polyester blended yarn are different but the spinning and finishing are the same. After being completely dried, those fabrics are set in a wind tunnel and the moisture adsorption rates are measured in the wind speeds of V=0.15 m/sec and 0.55m/sec.
There is a good agreement between the predicted adsorption and the observed ones. The equilibrium moisture content at V=0.55 m/sec is lower by 1-3% than that at V=0.15 m/sec, and the time for attaining at the equilibrium is shorter.
