WOVEN MESH FROM BRAIDED NYLON CORD

Abstract

The objective of this program was to develop a woven mesh material using MIL-C-5040, Type I cord and commercial grade, high tenacity nylon yarn in order to achieve a 1000-1200 lb./in. breaking strength in the warp and filling directions and a geometric porosity of 35%, or a permeability of 800-900 cu.ft./sq.ft./min. Binder yarns from 30 denier to 200 denier were evaluated in order to achieve the strongest possible bond between warp and filling cords. Various constructions, ranging from 7 ends and picks of cord to 9 ends and picks of cord, were evaluated to achieve the optimum combination of breaking strength and air permeability. Unusual problems were encountered in weaving the cord because of its bulk and stiffness. Considerable yardage would have to be manufactured in order to determine the commercial practicality of the manufacturing technique. This study demonstrated the feasibility of designing and weaving a fabric using a 100 lb. breaking strength cord in a crimpless weave for use in special types of parachute applications.
