Crimp-imbalanced fabric systems are accomplished by varying the levels of yarn crimp within a single fabric layer and across layers of a multi-layer fabric system. The method includes developing a crimp in the yarn utilized for producing a fabric layer by optionally pulling the yarn through a solution that substantially coats the yarn. The optionally removable coating has a thickness that ensures a proper amount of crimp in the yarn. The tension in the yarn is controlled the yarn is weaved and a crimp is applied in the yarn. Once the crimp is applied, families of the crimped yarn are utilized as a single layer or multiple layer system to increase performance attributes including enhanced energy absorption.
