The absorptive coefficiency (uptake) of water and several kinds of alcohol was examined after piling towels in a stack using the Larose Method measured with a laser scanning micrometer. This uptake profile was approximately expressed by the same differential equation as the diffusion equation. Using this method, uptake coefficients of β and α were obtained along the vertical and parallel directions to the plane of cloth respectively. The magnitude of these coefficients is a measure of liquid absorbency. As the number of towels in the stack increased, so did the value of β ; however, that of α remained almost constant. Equilibrium uptake was unrelated to the kind of liquid used, and the value decreased. When compared with the same number of towels in the stack, the value of β increased with the lowering of the viscosity of the liquid, but the relationship with α could not be clearly observed. These results were discussed using Poiseuille's law.
