<p>A helical textile (100, 240, 260, 280, 300, 320, 350, 360, 380) with a substantially uniform thickness has circumferential warp fibers (102, 208, 210, 256, 355, 365, 390) defining a radial textile width (281) from a textile inner diameter (202, 250, 268, 368, 282, 304, 326) to a textile outer diameter (204, 252, 266, 366, 284, 302, 328). The circumferential warp fibers (102, 208, 210, 256, 355, 365, 390) extend substantially in a first fiber direction. Weft fibers (104, 212, 214, 216, 218, 220, 222, 254, 262, 264, 362, 286, 287, 288, 289, 310, 312, 322, 324) are inserted in a weft region (325) between the textile inner diameter (202, 250, 268, 368, 282, 304, 326) and the textile outer diameter (204, 252, 266, 366, 284, 302, 328) extend substantially in a second fiber direction along a weft fiber axis (267, 265, 365, 366) having a predefined angle (±, ², A1, A2) with respect to a radial axis (272, 372) greater than zero degrees and less than ninety degrees. Knitted chain stitches (108) secure the weft fibers (104, 212, 214, 216, 218, 220, 222, 254, 262, 264, 362, 286, 287, 288, 289, 310, 312, 322, 324) to the circumferential warp fibers (102, 208, 210, 256, 355, 365, 390), where the knitted chain stitches (108) are knitted across the weft region (325) in a third fiber direction. The circumferential warp fibers (102, 208, 210, 256, 355, 365, 390) and the weft fibers (104, 212, 214, 216, 218, 220, 222, 254, 262, 264, 362, 286, 287, 288, 289, 310, 312, 322, 324) are non-interlaced, thereby forming a helical textile (100, 240, 260, 280, 300, 320, 350, 360, 380) having a substantially uniform thickness from the textile inner diameter (202, 250, 268, 368, 282, 304, 326) to the textile outer diameter (204, 252, 266, 366, 284, 302, 328).</p> |
