Abstract

A textile sleeve having a seamless, circumferentially continuous wall including a textile layer formed of yarns interlaced with one another. The textile layer having an outer surface and an opposite inner surface bounding an enclosed cavity extending lengthwise along a central longitudinal axis between opposite open ends. At least some of the yarns include multifilaments resistant to heat and monofilaments resistant to heat, and a silicone-based coating adhered to the outer surface.

Claims (20)

1 . A textile sleeve for routing and protecting an elongate member, comprising:

a seamless, circumferentially continuous wall, said circumferentially continuous wall including a textile layer having an outer surface and an opposite inner surface bounding an enclosed cavity extending lengthwise along a central longitudinal axis between opposite open ends, said textile layer being formed of yarns interlaced with one another, wherein at least some of said yarns include multifilaments resistant to heat and monofilaments resistant to heat, and a silicone-based coating adhered to said outer surface of said textile layer,

wherein said yarns include warp yarns extending generally parallel to said central longitudinal axis and weft yarns extending generally transversely to said central longitudinal axis, said warp yarns being woven with said weft yarns,

wherein said warp yarns are provided entirely from said multifilaments resistant to heat and said weft yarns are provided including said monofilaments resistant to heat.

2 . The textile sleeve of claim 1 , wherein said weft yarns are provided including said multifilaments resistant to heat.

3 . The textile sleeve of claim 2 , wherein said multifilaments resistant to heat are provided as meta-aramid.

4 . The textile sleeve of claim 2 , wherein said warp multifilaments resistant to heat are provided having a denier between about 100-3000 dtex and said weft multifilaments resistant to heat are provided having a denier between about 50-1000 dtex.

5 . The textile sleeve of claim 4 , wherein said monofilaments resistant to heat are provided having a diameter between about 0.1-0.5 mm.

6 . The textile sleeve of claim 3 , wherein said monofilaments resistant to heat are provided as PEEK.

7 . The textile sleeve of claim 1 , wherein said silicone-based coating includes at least one of a flame retardant and a heat stabilizer.

8 . The textile sleeve of claim 1 , wherein said silicone-based coating has a thickness between about 0.1-3.0 mm.

9 . The textile sleeve of claim 1 , wherein said textile layer is circumferentially continuous and seamless.

10 . The textile sleeve of claim 1 , wherein said textile layer has opposite edges extending lengthwise between said opposite open ends, said opposite edges being in overlapped relation with one another with a seam formed between said overlapped edges, wherein said silicone-based coating is circumferentially continuous and seamless to close off said seam between said overlapped opposite edges.

11 . A textile sleeve for routing and protecting an elongate member, comprising:

a seamless, circumferentially continuous wall, said circumferentially continuous wall including a textile layer having an outer surface and an opposite inner surface bounding an enclosed cavity extending lengthwise along a central longitudinal axis between opposite open ends, said textile layer being formed of yarns interlaced with one another, wherein at least some of said yarns include multifilaments resistant to heat and monofilaments resistant to heat, and a silicone-based coating adhered to said outer surface of said textile layer, wherein said multifilaments resistant to heat are provided as meta-aramid,

wherein said yarns include warp yarns extending generally parallel to said central longitudinal axis and weft yarns extending generally transversely to said central longitudinal axis, said warp yarns being woven with said weft yarns, and wherein said warp yarns include said multifilaments resistant to heat provided having a denier between about 100-3000 dtex and said weft yarns include said multifilaments resistant to heat provided having a denier between about 50-1000 dtex.

12 . The textile sleeve of claim 11 , wherein said weft yarns include said monofilaments resistant to heat provided having a diameter between about 0.1-0.5 mm.

13 . A textile sleeve for routing and protecting an elongate member, comprising:

a seamless, circumferentially continuous wall, said circumferentially continuous wall including a textile layer having an outer surface and an opposite inner surface bounding an enclosed cavity extending lengthwise along a central longitudinal axis between opposite open ends, said textile layer being formed of yarns interlaced with one another, wherein at least some of said yarns include multifilaments resistant to heat and monofilaments resistant to heat, and a silicone-based coating adhered to said outer surface of said textile layer, wherein said yarns include warp yarns extending generally parallel to said central longitudinal axis and weft yarns extending generally transversely to said central longitudinal axis, said warp yarns being woven with said weft yarns, wherein said warp yarns include said multifilaments resistant to heat provided having a denier between about 100-3000 dtex and said weft yarns include said multifilaments resistant to heat provided having a denier between about 50-1000 dtex.

14 . The textile sleeve of claim 13 , wherein said monofilaments resistant to heat are provided having a diameter between about 0.1-0.5 mm.
