Claim Text:
1. A helical textile having a substantially uniform thickness comprising: a plurality of circumferential warp fibers defining a radial textile width from a textile inner diameter to a textile outer diameter, the plurality of circumferential warp fibers extending substantially in a first fiber direction; a plurality of weft fibers inserted in a weft region between the textile inner diameter and the textile outer diameter and extending substantially in a second fiber direction along a weft fiber axis, the weft fiber axis having a predefined angle between ten and eighty degrees with respect to a radial axis; and a plurality of knitted chain stitches securing the plurality of weft fibers to the plurality of circumferential warp fibers; wherein the plurality of circumferential warp fibers and the plurality of weft fibers are non-interlaced, thereby forming a helical textile having a substantially uniform thickness from the textile inner diameter to the textile outer diameter; and wherein at least one of the plurality of weft fibers extends only partially between the textile inner diameter and the textile outer diameter.
