A STUDY OF THE EFFECTS OF FABRIC GEOMETRY VARIABLES ON AIR PERMEABILITY

Abstract

A series of specially designed nylon parachute fabrics was selected to represent extremes in cloth construction and to demonstrate fundamentals of fabric geometry. By means of a somewhat unusual test arrangement it was possible to indicate the relationship of fabric geometry to air permeability at several pressure differentials. Through the process of establishing the ratio of total fabric area to interstice areas data were obtained on yarn widths as they lie in the cloth. These data were obtained on a variety of twist constructions and will provide a knowledge and background of design data for present application and future studies in this area.
