To analyze the fundamental behavior of a wool assembly in steeping and washing bowls, the author has studied the process in which an assembly floating on a liquid surface begins to sink. The time (t_??_) needed for an assembly to begin sinking has been measured for various values of porosity (Ph) by using distilled water of various temperatures, trichlene and methyl alcohol of a normal temperature and a solution of non-ionic wetting agent of various concentrations (Cp) and of a normal temperature.
The difference in t_??_ between various values of Ph is small if the concentration of the wetting agent is high (dense). The difference in t_??_, however, is high for a low concentration of the wetting agent, the maximum of t_??_ occuring at Ph=80%. The relation between log t_??_ and log Cp is practically linear and had a constant tangent if the porosity degree is fixed at a standard vlaue. When this wetting agent solution is used, the porosity arranged in order from fastest to slowest sinking of scoured wool is Ph=97>95>90>70>75>85>80%.
