Abstract : Application of hydrodynamic theory to the passage of air through textile fabrics is discussed. Flow-pressure results for a group of fabrics covering a wide range of air permeabilities are recorded and the data analyzed. Laminar flow fiscosity effects as well as increased kinetic energy effects are shown to be operative, and in some instances the flow pattern is shown to exhibit a behavior attributable to the presence of pores of widely differing size in the same fabric. Loss of energy from barrier effects (shock forces) is considered, and the case of flow through multiple layers of fabric is examined. Some estimates of pore size are computed from particular experimental data. (Author)
