Abstract:
The objective of this contract was to develop a woven mesh material, using Nomex as the raw material yarn, having a 100 pounds per inch breaking strength in both directions and a geometric porosity of 35 or a permeability of 900-1000 cubic feetminutesquare foot. Twist levels from 5 to 20 turns per inch were evaluated in both warp and filling directions to determine the effect of twist on the permeability. Various constructions and weaves ranging from plain weave to mock leno were used to determine the maximum permeability with the required breaking strength. The mock leno weave was determined to be the most satisfactory to achieve a proper balance of properties. The level of twist affected the air permeability far more dramatically than was expected with the result that a rather high twist was used in the final product. This study demonstrated the feasibility of designing and weaving a fabric from Nomex nylon which would have the properties for use in special type of parachute applications. Author
