Pore-Size Distribution in Textiles-A Study of Windproof and Water-Resistant Cotton Fabrics

A modified method for evaluating the distribution of pore spaces within a textile fabric, based on the principle outlined in the preceding paper in this series [1], is described. Data are reported for 14 tight fabrics, 6 of which had been treated with a water-repellent finish. The porosities of these fabrics are compared with the results of air- and hydrostatic-permeability measurements.
