Abstract

A textile sleeve for protecting elongate members against EMI and method of construction thereof is provided. The sleeve includes a wall having opposite edges extending lengthwise in generally parallel relation with a longitudinal axis between opposite ends. The opposite edges are configured to overlap one another to bound a central cavity extending between the opposite ends. The wall includes warp filaments, extending generally parallel to the longitudinal axis, woven with weft filaments, extending generally transversely to the warp filaments. The warp filaments include substantially electrically non-conductive multifilaments woven in a plain weave pattern with the weft filaments and electrically conductive members woven with the weft filaments to form a plurality of floats, with each of the floats extending over at least two adjacent ones of the weft filaments.

First claim

What is claimed is:

1. A textile sleeve for protecting elongate members against abrasion and EMI, comprising:
a wall having opposite edges extending lengthwise in generally parallel relation with a longitudinal axis between opposite ends, said opposite edges being configured to overlap one another to bound an enclosed cavity extending between said opposite ends, said wall having warp filaments extending generally parallel to said longitudinal axis woven with weft filaments extending generally transversely to said warp filaments, said warp filaments including substantially electrically non-conductive multifilaments woven in a plain weave pattern with said weft filaments and electrically conductive members woven with said weft filaments, wherein said electrically conductive members form a plurality of floats, with each of said floats extending over at least two adjacent ones of said weft filaments.

2. The textile sleeve of claim 1 , wherein said electrically conductive members are metal-plated.

3. The textile sleeve of claim 2 , wherein said metal-plated electrically conductive members are metal-plated multifilaments.

4. The textile sleeve of claim 3 , wherein said metal-plated multifilaments include metal-plated multifilaments of aramid.

5. The textile sleeve of claim 2 , wherein separate ones of said metal-plated electrically conductive members include a plurality of metal-plated wires.

6. The textile sleeve of claim 5 , wherein said metal-plated wires include metal-plated stainless steel wires.

7. The textile sleeve of claim 5 , wherein said plurality of metal-plated wires each include between about 10-30 metal plated wires.

8. The textile sleeve of claim 2 , wherein said metal-plated electrically conductive members include an outer plating of at least one of copper, nickel and silver.

9. The textile sleeve of claim 1 , wherein said substantially electrically non-conductive multifilaments and said electrically conductive members are staggered with one another in alternating relation.

10. The textile sleeve of claim 1 , wherein said substantially electrically non-conductive multifilaments include aramid multifilaments.

11. The textile sleeve of claim 1 , further including an organic or inorganic coating bonding said warp and weft filaments together.

12. The textile sleeve of claim 1 , wherein said electrically conductive members are woven in a twill pattern.

13. The textile sleeve of claim 1 , wherein said electrically conductive members are woven in a satin pattern.

14. The textile sleeve of claim 1 , wherein said floats face radially inwardly toward the cavity.

15. The textile sleeve of claim 1 , wherein said weft filaments include heat-set filaments biasing said opposite edges into overlapping relation with one another.

16. A method of constructing a textile sleeve for protecting elongate members against abrasion and EMI, comprising:
forming a wall having opposite edges extending lengthwise in generally parallel relation with a longitudinal axis between opposite ends, with said opposite edges being configured to overlap one another to bound a central cavity extending between said opposite ends;
forming said wall by weaving warp filaments extending generally parallel along their full length to said longitudinal axis and terminating at said opposite ends with weft filaments extending generally transversely to said warp filaments; and
weaving said warp filaments including substantially electrically non-conductive multifilaments woven in a plain weave pattern with said weft filaments and including electrically conductive members forming a plurality of floats, with each of said floats extending over at least two adjacent ones of said weft filaments.

17. The method of claim 16 , further including weaving said substantially electrically non-conductive multifilaments and said electrically conductive members in staggered, alternating relation with one another.

18. The method of claim 16 , further including providing said substantially electrically non-conductive multifilaments as aramid multifilaments.

19. The method of claim 16 , further including providing said electrically conductive members as metal-plated filaments.

20. The method of claim 19 , further including providing said metal-plated filaments including metal-plated aramid multifilaments.

21. The method of claim 19 , further including providing said metal-plated filaments including metal-plated wire filaments.

22. The method of claim 21 , further including providing said metal-plated wire filaments including metal-plated stainless steel wire filaments.

23. The method of claim 19 , further including providing said metal-plated filaments including an outer plating of at least one of copper, nickel and silver.

24. The method of claim 16 , further including applying an organic or inorganic coating on said warp and weft filaments to bond said warp and weft filaments with one another.

25. The method of claim 16 , further including weaving said electrically conductive members in a twill pattern.

26. The method of claim 16 , further including weaving said electrically conductive members in a satin pattern.

27. The method of claim 16 , further including forming said floats to face radially inwardly into the cavity.

28. The method of claim 16 , further including heat-setting at least some of said weft filaments to bias said opposite edges into overlapping relation with one another.
