Abstract
Crimp-imbalanced protective fabric is accomplished by varying the levels of yarn crimp within and across a layer or layers of a multi-layer fabric armor system. The method includes developing a crimp in the yarn (utilized for producing a fiber layer) by pulling the yarn through a solution that substantially coats the yarn. The 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 layer or layered to produce a soft armor form.
