A fabric system and manufacturing method for achieving higher fiber crimp in selected fibers to reduce initial fabric modulus (gain higher elongation) in the thread-line direction. The fabric system and method utilizes processing yarns of higher shrinkage than the product reinforcing yarns. The processing yarns are woven together with the reinforcing yarns in various patterns and combinations dependent on the desired fabric characteristics. The fabric is processed thermally or otherwise to impart crimp into the reinforcing yarns by the differential shrinkage of the processing yarns. By adjusting the ratio of reinforcing yarns to processing yarns, a unique set of characteristics in the fabric is created, specifically a lower modulus, higher initial elongation in the thread-line direction of the reinforcing yarn.

A coated, bi-directional substrate design for an aircraft escape slide airbeam, where the longitudinal strength and hoop strength of the substrate and the coating applied thereto are optimized to the application. Less than 45% of the total substrate fiber content is in the longitudinal direction of the substrate, and the longitudinal strength of the substrate is approximately 50% of the hoop strength. The substrate is constructed of nylon, polyester, aramid, para-aramid or liquid crystal polymer fibers, and either polyurethane coatings and adhesives or polyether polyurethane coatings and adhesives. The warp yarns are less than the denier of the fill yarns and are woven in groups of 2 or more yarns to improve the tear strength of the fabric in the warp direction.
