Abstract

A protective textile sleeve for routing and protecting elongate members against impact and method of constructed thereof are provided. The sleeve includes a plurality of yarns interlaced with one another, with the interlaced yarns forming an elongate, circumferentially continuous, tubular wall extending lengthwise along a longitudinal axis between opposite open ends. At least some of the plurality of yarns include tubular yarn having a central cavity extending along the length of the tubular yarn, thereby providing an impact resistant, dual layered wall to the tubular yarn. The sleeve can be constructed in a weaving, braiding or knitting process, wherein the tubular yarn can be interlaced as a woven yarn, braided yarn, or knit yarn, and further, the tubular yarn can be interlaced as an inserted yarn.

First claim

What is claimed is:

1. A textile sleeve for routing and protecting elongate members, comprising:
a plurality of yarns interlaced with one another forming an elongate, circumferentially continuous, tubular wall extending lengthwise along a longitudinal axis between opposite open ends, wherein at least some of said plurality of yarns include tubular yarn.

2. The textile sleeve of claim 1 , wherein said tubular yarn has a tubular braided wall formed by a plurality of filaments braided with one another.

3. The textile sleeve of claim 2 , wherein said plurality of filaments forming said tubular braided wall include a heat-shrinkable filament.

4. The textile sleeve of claim 3 , wherein the entirety of said plurality of filaments forming said tubular braided wall are heat-shrinkable filaments.

5. The textile sleeve of claim 4 , wherein at least some of said plurality of yarns forming said tubular wall are non-heat-shrinkable filaments.

6. The textile sleeve of claim 2 , wherein at least some of said plurality of filaments forming said tubular braided wall are non-heat-shrinkable filaments.

7. The textile sleeve of claim 6 , wherein the entirety of said plurality of filaments forming said tubular braided wall are non-heat-shrinkable filaments.

8. The textile sleeve of claim 7 , wherein at least some of said plurality of yarns are heat-shrinkable yarns.

9. The textile sleeve of claim 1 , wherein at least some of said plurality of yarns are heat-shrinkable yarns.

10. The textile sleeve of claim 9 , wherein the entirety of said plurality of yarns are heat-shrinkable yarns.

11. The textile sleeve of claim 1 , wherein said tubular yarn has an inner surface bounding a cavity having a diameter between about 0.5-10 mm.

12. The textile sleeve of claim 1 , wherein said plurality of yarns are braided with one another.

13. The textile sleeve of claim 1 , wherein said plurality of yarns include warp yarn extending generally parallel to said longitudinal axis and weft yarn extending generally transversely to said warp yarn, said warp yarn and said weft yarn being woven with one another.

14. The textile sleeve of claim 13 , wherein at least some said warp yarn is provided as said tubular yarn and at least some of said warp yarn is provided as non-tubular yarn.

15. The textile sleeve of claim 14 , wherein a plurality of said warp yarn is provided as said tubular yarn in immediately adjacent relation with one another and a plurality of said non-tubular yarn is provided in immediately adjacent relation with one another.

16. The textile sleeve of claim 14 , wherein at least some said weft yarn is provided as said tubular yarn and at least some of said weft yarn is provided as non-tubular yarn.

17. The textile sleeve of claim 13 , wherein at least some said weft yarn is provided as said tubular yarn and at least some of said weft yarn is provided as non-tubular yarn.

18. The textile sleeve of claim 17 , wherein a plurality of said weft yarn is provided as said tubular yarn in immediately adjacent relation with one another and a plurality of said non-tubular yarn is provided in immediately adjacent relation with one another.

19. The textile sleeve of claim 13 , wherein said elongate, circumferentially continuous, tubular wall has a uniform density along its length.

20. The textile sleeve of claim 13 , wherein said elongate, circumferentially continuous, tubular wall has a non-uniform density along at least one of its length and circumference.

21. The textile sleeve of claim 1 , wherein said elongate, circumferentially continuous, tubular wall has a uniform density along its length.

22. The textile sleeve of claim 1 , wherein said elongate, circumferentially continuous, tubular wall has a non-uniform density along at least one of its length and circumference.

23. A method of constructing a textile sleeve for routing and protecting elongate members, comprising:
interlacing a plurality of yarns with one another to form an elongate, circumferentially continuous, tubular wall extending lengthwise along a longitudinal axis between opposite open ends, wherein at least some of the plurality of yarns include tubular yarn.

24. The method of claim 23 , further including providing the tubular yarn having a tubular braided wall formed by a plurality of filaments braided with one another.

25. The method of claim 24 , further including providing the plurality of filaments forming the tubular braided wall including a heat-shrinkable filament.

26. The method of claim 25 , further including providing the entirety of the plurality of filaments forming the tubular braided wall as heat-shrinkable filaments.

27. The method of claim 26 , further including providing at least some of the plurality of yarns forming the tubular braided wall as non-heat-shrinkable filaments.

28. The method of claim 24 , further including providing at least some of the plurality of filaments forming the tubular braided wall as non-heat-shrinkable filaments.

29. The method of claim 24 , further including providing the entirety of the plurality of filaments forming the tubular braided wall as non-heat-shrinkable filaments.

30. The method of claim 29 , further including providing at least some of the plurality of yarns as heat-shrinkable yarns.

31. The method of claim 23 , further including providing at least some of the plurality of yarns as heat-shrinkable yarns.

32. The method of claim 31 , further including providing the entirety of the plurality of yarns as heat-shrinkable yarns.

33. The method of claim 23 , further including providing the tubular yarn having an inner surface bounding a cavity having a diameter between about 0.5-10 mm.

34. The method of claim 23 , further including performing the interlacing via a braiding process.

35. The method of claim 23 , further including performing the interlacing via a weaving process with the plurality of yarns including warp yarn extending generally parallel to the longitudinal axis and weft yarn extending generally transversely to the warp yarn.

36. The method of claim 35 , further including providing at least some of the warp yarn as tubular yarn and providing at least some of the warp yarn as non-tubular yarn.

37. The method of claim 36 , further including weaving a plurality of the warp tubular yarn in immediately adjacent relation with one another and weaving a plurality of the warp non-tubular yarn in immediately adjacent relation with one another.
