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.

The method includes acquiring information indicating whether or not the measuring tool is held in the component crimping apparatus, and, in the case where the information indicating that the measuring tool is held is acquired, positioning the measuring tool identically as the workpiece, and executing the pressing process on the component to be attached to the measuring tool after the positioning.

Abstract: The invention describes a low tension relax process and corresponding apparatus, wherein a tension gate is incorporated into a relax zone in a yarn production process. The tension gate can be anything that produces a drag on the yarn threadline such as an air drag device, a liquid drag device, or a solid surface contact drag device, or a combination of these. A tension gate is a device which when used in a relax zone has an outlet yarn tension greater than the inlet yarn tension thus creating a tension differential. The tension gate provides a tension differential of at least 5 mg per denier. A relax zone is typical found in a spin-drawing process, a draw-twisting process, a draw-winding process, or a draw-bulking process. The invention describes a yarn making process with a tension gate in the relax zone wherein the tension gate creates a tension differential on said yarn of at least 5 milligrams per denier.
