Drying properties of regular and modified acrylic fabrics were studied. A modified acrylic fabric has many micropores in the fiber. The infrared analysis indicates that the regular fabrics have almost the same chemical moieties as the modified, whereas their sorptive behaviours are different each other.
The measurements for drying processes were carried out in a box at 20°C and 63% R. H. All of drying characteristic curves showed convex upward. In the preceding report, the following characteristic equation (1) was proposed for drying process. The decreasing coefficient, k, was determined by the slope of the following equation (2). k became larger in order of wool, cotton, modified acrylic fabric, nylon, regular acrylic fabric. The k value for the modified acrylic fabrics were nearly same as that for cotton. Plots for the free moisture content versus the reciprocal of the decreasing coefficient also gave a straight line.
