Abstract
The air permeability of special weaves of nylon, orlon, and dacron parachute-type fabrics was determined using a sample 6.05 in. diameter. The permeometer used in the investigation permitted testing the fabric samples at pressure differentials across the cloth as high as 55 in. of water. The 61 experimental cloths woven at the Georgia Inst. of Tech. (GT) were subjected to this test procedure. Air permeability data for the GT-woven fabrics, Bally Ribbon cloths, and 10 fabrics furnished by the Air Force are presented in graphical form as volumetric flow vs static pressure differential across the cloth. The number of ends per in. in warp, picks per in. in the filling, and denier of yarns affected the air permeability of these fabrics. The finishing of the fabrics affected the permeability more than any other variable. Tests to determine the effect of variation of the weave pattern failed to show significant differences on this account.
