Helical textile with uniform thickness

1. A helical textile having a substantially uniform thickness comprising:

circumferential warp fibers defining a radial textile width from a textile inner diameter to a textile outer diameter;

non-interlaced radially aligned weft fibers of varying lengths to maintain constant textile thickness, the warp fibers and weft fibers not crimped together; and

non-reinforcing binding yarns securing the warp fibers to the weft fibers with chain stitches knitted across the radial textile width, thereby forming a helical textile.

2. The textile of claim 1 , wherein

the warp fibers form layers and are circumferentially parallel to each other within the same layer, and

the weft fibers form layers and are radially parallel to each other within the same layer.

3. The textile of claim 2 , wherein alternating warp layers and weft layers are stacked to form a helical textile.

4. The textile of claim 1 wherein the weft fibers of different lengths are arranged so that one end of each weft fiber is at the outside diameter of the helical textile.

5. The textile of claim 1 , wherein the warp and weft fibers are selected from the group consisting of carbon, graphite, glass, and ceramic.

6. A helical textile made by a process comprising the steps of:

providing a warp knitting machine having at least one conical take-up roll;

adjusting weft insertion to insert weft fibers in a repeating pattern of varying lengths;

warp knitting a helical textile having circumferential warp fibers, a non-interlaced radially aligned weft, and substantially uniform textile thickness, the helical textile defining a radial textile width from a textile inner diameter to a textile outer diameter; and

securing the weft fibers to the circumferential warp with chain stitches knitted across the radial textile width.

7. The helical textile of claim 1 , wherein the weft fibers comprise individual fibers extending from the textile outer diameter towards the textile inner diameter.
