Abstract

A textile sleeve for routing and protecting a plurality of elongate members in spaced relation from one another is provided. The sleeve includes a single piece, monolithic wall of interlaced yarn extending lengthwise between opposite ends of the sleeve. The wall includes a plurality of circumferentially continuous, tubular wall sections extending lengthwise between the opposite ends, with adjacent tubular wall sections being fixed in laterally spaced relation from another by an intervening single layer section. At least some of the yarn within each tubular wall section is provided as heat-shrinkable yarn, thereby providing each tubular wall section as being heat-shrinkable from a first, diametrically enlarged assembly state to a second, diametrically constricted state about a corresponding elongate member contained therein.

First claim

What is claimed is:

1. A textile sleeve for routing and protecting elongate members, comprising:
a single piece, monolithic wall of interlaced yarn extending lengthwise between opposite ends of the sleeve, said wall including a plurality of circumferentially continuous, tubular wall sections extending lengthwise between said opposite ends, adjacent tubular wall sections being fixed in laterally spaced relation from another by an intervening single layer section having a plurality of lengthwise extending yarns interlaced with a plurality of circumferentially extending yarns, at least some of said yarn within each said tubular wall section being heat-shrinkable yarn, each said tubular wall section being heat-shrinkable from a first, diametrically enlarged assembly state to a second, diametrically constricted state about a corresponding elongate member contained therein.

2. The textile sleeve of claim 1 , wherein the wall is woven with warp yarns extending lengthwise between opposite ends of the sleeve and fill yarns extending generally transversely to the warp yarns, wherein at least some of said fill yarn is provided as said heat-shrinkable yarn.

3. The textile sleeve of claim 2 , wherein the entirety of the fill yarn is heat-shrinkable yarn.

4. The textile sleeve of claim 2 , wherein the fill yarn includes non-heat-shrinkable multifilament yarn.

5. The textile sleeve of claim 2 , wherein the warp yarns include non-heat-shrinkable multifilaments and/or monofilaments.

6. The textile sleeve of claim 5 , wherein the entirety of the warp yarns include non-heat-shrinkable multifilaments and/or monofilaments.

7. The textile sleeve of claim 1 , wherein the wall is weft knit from weft knit stitches.

8. The textile sleeve of claim 7 , wherein at least some of the weft knit stitches within each tubular wall section include non-heat-shrinkable filaments.

9. The textile sleeve of claim 7 , wherein the entirety of the weft knit stitches within each tubular wall section include heat-shrinkable filaments.

10. A textile sleeve for routing and protecting elongate members, comprising:
a single piece, monolithic wall of interlaced yarn extending lengthwise between opposite ends of the sleeve, said wall including a plurality of circumferentially continuous, tubular wall sections extending lengthwise between said opposite ends, adjacent tubular wall sections being fixed in laterally spaced relation from another by an intervening single layer section having a plurality of lengthwise extending yarns interlaced with a plurality of circumferentially extending yarns, at least some of said yarn within each said tubular wall section being heat-shrinkable yarn, each said tubular wall section being heat-shrinkable from a first, diametrically enlarged assembly state to a second, diametrically constricted state about a corresponding elongate member contained therein, wherein at least one of the plurality of circumferentially continuous, tubular wall sections includes a plurality of separate cavities extending lengthwise in side-by-side relation with one another between the opposite ends, wherein the plurality of separate cavities are separated from one another by a wall of the interlaced yarn.

11. A method of constructing an elongate textile sleeve for routing and protecting a plurality of elongate members in spaced relation from one another, comprising:
interlacing yarn to form a single piece, monolithic wall;
forming the wall including a plurality of circumferentially continuous, tubular wall sections extending lengthwise between the opposite ends;
forming an intervening single layer section having a plurality of lengthwise extending yarns interlaced with a plurality of circumferentially extending yarns between adjacent tubular wall sections to maintain the adjacent tubular wall sections in laterally spaced relation with one another; and
interlacing at least some of the yarn within each tubular wall section as heat-shrinkable yarn, thereby allowing each tubular wall section to be heat-shrunk from a first, diametrically enlarged assembly state to a second, diametrically constricted state about a corresponding elongate member contained therein.

12. The method of claim 11 , further including forming at least one of the plurality of circumferentially continuous, tubular wall sections including a plurality of separate cavities extending lengthwise in side-by-side relation with one another between the opposite ends.

13. The method of claim 11 , further including performing the interlacing by weaving warp yarns extending lengthwise between opposite ends of the sleeve with fill yarns extending generally transversely to the warp yarns.

14. The method of claim 13 , further including weaving the entirety of the fill yarn as heat-shrinkable yarn.

15. The method of claim 13 , further including weaving the fill yarn including non-heat-shrinkable multifilament yarn.

16. The method of claim 13 , further including weaving the warp yarns as non-heat-shrinkable yarn.

17. The method of claim 11 , further including performing the interlacing in a weft knitting process.

18. The method of claim 17 , further including forming at least some of the knit stitches within each tubular wall section from non-heat-shrinkable yarn.

19. The method of claim 17 , further including forming each of the knit stitches within each tubular wall section from heat-shrinkable yarn.

20. The method of claim 12 , further including separating the cavities from one another by a wall of the interlaced yarn.
