Abstract
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.
