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.
Abstract: There is provided herein a woven sailcloth having a weight of at least about 6 and comprising warp yarns and fill yarns and having a 1% warp of at least about 80 and/or a warp efficiency of at least about 13, wherein the fill yarns are pre-crimped, and wherein the warp yarns and the fill yarns are weaved in a plain weave in which the ratio of fill yarn count to warp yarn count is about 1.1:1 to about 1.8:1 and the ratio of warp yarn density to fill yarn density is about 1.2:1 to about 1.9:1. There is also provided herein sails made from the sailcloth and a method for making the sail.

Abstract: A method of weaving industrial textiles to a single warp platform, and textiles made thereby. The method comprises identifying optimal fabric characteristics for selected uses to determine groups of suitable fabrics; selecting a first group, identifying fabric properties for optimal characteristics, and identifying optimal properties for warp yarns to be used for all fabrics in the group; selecting a structure type and weave design for each fabric of the group; providing a loom with selected shedding options and installing warp yarns having the identified optimal properties. Thereafter, each fabric in the group can be woven without changing the warp yarns, simply by identifying properties for weft yarns to correspond with the weave design of the respective fabric, setting the loom accordingly and weaving the fabrics as required, adjusting only the weft parameters between successive fabrics, resulting in increased efficiency of manufacturing and avoiding time consuming warp changes between fabrics.

Abstract: Fabric structures having two connection segments and an expansion segment between the two connection segments are provided. The fabric structure includes ground yarns that form a sheath, binder yarns, elongation yarns surrounded by the sheath, and lateral yarns. In the expansion segment, at least some of the lateral yarns are interwoven with the elongation yarns to connect the elongation yarns laterally with the sheath. Heat treatment of the expansion segment shrinks the length of the elongation yarns during manufacture. The sheath does not substantially shrink from the heat treatment relative to the elongation yarns and gathers together in an accordion-like arrangement. A tensile load applied to the fabric structure stretches the elongation yarns and unfolds the gathered sheath. The high strength sheath supports the tensile load when completely unfolded, while the elongation yarns absorbs energy as the fabric structure stretches or elongates.

Abstract: A method for fabricating multilayer fabrics having a prescribed integration pattern and an apparatus of implementing same. In one embodiment, the method include the steps of providing a plurality of winding yarn carriers arranged in a multilayer structure along a first direction and configured such that each winding yarn carrier is operably movable with respect to one another along a second direction that is perpendicular to the first direction, forming a plurality of crossover points of the winding yarns by moving at least one winding yarn carrier along the second direction according to the integration pattern, transporting the binder yarns through the plurality of winding yarn layers at predetermined locations along the first direction, and locking the binder yarns in place, pushing the binder yarns toward the fell of the multilayer fabrics, and taking up the formed multilayer fabrics.
