A weave pattern and method for weaving that provides stability to high performance fabrics, such as fabrics used for life protection and composite use, is provided. An additional set of yarn may be added in the warp direction, such that there are two sets of warp yarns per fill yarn alternating throughout the structure of the fabric. This second set of warp yarn locks the fill yarns in place, subsequently interlocking and stabilizing the fabric pattern. This stabilization increases tensile strength, tightness, stiffness, and also improves the handling and cutting of the fabric by resulting in decreased fraying and fiber loss during product construction. Also, the fabric maintains proper shape and form due to the 90 degree interlacing of warp and fill yarns. In this way, the fabric may have the enhanced performance characteristics of a looser weave in combination with the enhanced handleability of a tighter weave.

1. A woven fabric comprising: a fill yarn set, a first warp yarn set, and a second warp yarn set woven into a single layer;wherein said first warp yarn set and said fill yarn set are woven into a twill weave pattern; andsaid second warp yarn set interposed within said first warp yarn set, said second warp yarn set interrupting said twill weave pattern to lock said fill yarns into position to prevent fraying when said woven fabric is cut. 2. The woven fabric according to claim 1, wherein yarns of the first warp yarn set and yarns of the second warp yarn set alternate in a ratio. 3. The woven fabric according to claim 2, wherein said ratio is selected from the range of 2:1 to 5:1. 4. The woven fabric according to claim 2, wherein said ratio is selected from the range of 2:1 to 3:1. 5. The woven fabric according to claim 1, wherein said fill yarn set, said first warp yarn set, and said second warp yarn set include fibers selected from a group consisting of aramids, copolymer aramids, ultra high molecular weight polyethylene, glass, quartz, and carbon. 6. The woven fabric according to claim 5, wherein said twill weave pattern is a 2/2 twill weave pattern. 7. The woven fabric according to claim 1, wherein said second warp yarn set is woven into a plain weave pattern, so that said second warp yarns alternate in a repeating over and under pattern with respect to said fill yarns. 8. The woven fabric according to claim 1, wherein the yarns of the first warp yarn set have a first denier and the yarns of the second warp yarn set have a second denier, the first and second deniers being different from one another. 9. The woven fabric according to claim 8, wherein the first denier is in the range of 100-2000, and the second denier is in the range of 50-500. 10. A woven fabric comprising: a fill yarn set, a first warp yarn set, and a second warp yarn set woven into a single layer;wherein said first warp yarn set and said fill yarn set are woven into a basket weave pattern; andsaid second warp yarn set interposed within said first warp yarn set, said second warp yarn set interrupting said basket weave pattern to lock said fill yarns into position to prevent fraying when said woven fabric is cut. 11. The woven fabric according to claim 10, wherein yarns of the first warp yarn set and yarns of the second warp yarn set alternate in a ratio. 12. The woven fabric according to claim 10, wherein said ratio is selected from the range of 2:1 to 5:1. 13. The woven fabric according to claim 12, wherein said ratio is selected from the range of 2:1 to 3:1. 14. The woven fabric according to claim 10, wherein said fill yarn set, said first warp yarn set, and said second warp yarn set include fibers selected from a group consisting of aramids, copolymer aramids, ultra high molecular weight polyethylene, glass, quartz, and carbon. 15. The woven fabric according to claim 10, wherein said second warp yarn set is woven into a plain weave pattern, so that said second warp yarns alternate in a repeating over and under pattern with respect to said fill yarns. 16. The woven fabric according to claim 10, wherein the yarns of the first warp yarn set have a first denier and the yarns of the second warp yarn set have a second denier, the first and second deniers being different from one another. 17. The woven fabric according to claim 16, wherein the first denier is in the range of 100-2000, and the second denier is in the range of 50-500. 18. A woven fabric comprising: a fill yarn set, a first warp yarn set, and a second warp yarn set woven into a single layer;wherein said first warp yarn set and said fill yarn set are woven into a satin weave pattern, and wherein the yarns of the first warp yarn set have a denier in the range of 100-2000, and the yarns of the second warp yarn set have a denier in the range of 50-500;said second warp yarn set interposed within said first warp yarn set, said second warp yarn set interrupting said satin weave pattern to lock said fill yarns into position to prevent fraying when said woven fabric is cut; andwherein said fill yarn set, said first warp yarn set, and said second warp yarn set include fibers selected from a group consisting of aramids, copolymer aramids, ultra high molecular weight polyethylene, glass, quartz, and carbon. 19. The woven fabric according to claim 18, wherein said second warp yarn set is woven into a plain weave pattern, so that said second warp yarns alternate in a repeating over and under pattern with respect to said fill yarns. 20. The woven fabric according to claim 18, wherein yarns of the first warp yarn set and yarns of the second warp yarn set alternate in a ratio selected from the range of 2:1 to 5:1.
