Twenty-four differently constructed samples of nylon cloth in the desired weight range wore woven, finished and tested. A special mathematical study of the relationship between air permeability at 12 inch of water pressure differential and at higher pressure differentials was made. This discloses that a linear relationship in these values exists when plotted on full logarithmic graph paper.
