Abstract

A jacket for an elongated assembly is disclosed. The jacket, which may be a tubular shape or sheet, comprises a film layer to surround a core member of the elongated assembly, wherein the film layer has a first surface to be arranged abutting the core member in a non-bonded relationship; a braided, woven, or warp-knit layer comprising high-melt filament having a titer from 30 to 800 denier; and a bonding region between the braided, woven, or warp-knit layer and a second surface of the film layer, opposing to the first surface, to adhere at least a portion of the high-melt fibers. The jacket may further comprise an inner film layer in a non-bonded relationship with the film layer.

First claim

What is claimed is:

1. A jacket for an elongated assembly, the jacket comprising:
a film layer configured to surround a core member of the elongated assembly,
wherein the film layer has a first surface and an opposing second surface,
wherein the first surface faces the core member,
wherein the first surface is not bonded to the core member;

a braided, woven, or warp-knit layer comprising a high-melt filament,
wherein the high-melt filament has a titer from 30 to 800 denier; and

a bonding layer positioned between the braided, woven, or warp-knit layer and the second surface of the film layer,
wherein the bonding layer is configured to adhere at least a portion of the high-melt filament to the second surface of the film layer;
wherein the bonding layer does not pass through the braided, woven, or warp-knit layer.

2. The jacket of claim 1 , wherein the jacket is a tubular member or formed by wrapping a sheet to surround the core member.

3. The jacket of claim 1 , further comprising an inner film layer, wherein the inner film layer is to be disposed between the core member and film layer.

4. The jacket of claim 3 , wherein the inner film layer and the film layer are arranged in a non-bonded relationship.

5. The jacket of claim 3 , wherein the inner film layer comprises a fluoropolymer, a polyimide, polyamide, or UHMWPE.

6. The jacket of claim 3 , wherein the inner film layer is a current-limiting insulation and fluid barrier element.

7. The jacket of claim 3 , wherein the inner film layer has a thickness from 0.010 mm to 5 mm.

8. The jacket of claim 1 , wherein the film layer comprises a fluoropolymer, a polyimide, polyamide, or UHMWPE.

9. The jacket of claim 1 , wherein the film layer has a thickness from 0.010 mm to 5 mm.

10. The jacket of claim 1 , wherein the high-melt filament comprises fluoropolymer fibers, polyamide fibers, polyester fibers, UHMWPE, meta-aramids, or para-aramids.

11. The jacket of claim 1 , wherein the high-melt filament having a titer from 45 to 600 denier.

12. The jacket of claim 1 , wherein the bonding layer comprises one or more of a fluorinated ethylene propylene (FEP), perfluoroalkoxy polymer (PFA), or a silicone adhesive.

13. The jacket of claim 1 , wherein the high-melt filament is bonded to the film layer using at least one of plasma or heat.

14. The jacket of claim 1 , wherein the jacket is flexible and has a low force to plastic deformation.

15. The jacket of claim 1 , wherein the braided, woven, or warp-knit layer comprises an outer surface that is resistant to wrinkling when the jacket is assembled with the elongated assembly and bent.

16. The jacket of claim 1 , wherein the jacket has an abrasion resistance of at least 15% greater than the abrasion resistance of a jacket without a bonding layer.

17. The jacket of claim 1 , wherein the jacket has a cut-through resistance higher than the cut-through resistance of a jacket without a bonding layer.

18. The jacket of claim 1 , wherein the jacket has a cut-through resistance at 23° C. of at least 10% greater than the cut-through resistance of a jacket without a bonding layer.

19. A jacket for an elongated assembly, the jacket comprising:
a film layer;
a braided, woven, or warp-knit layer comprising a high-melt filament having a titer from 30 to 800 denier; and
a bonding layer between the braided, woven, or warp-knit layer and the film layer,
wherein the bonding layer is configured to adhere at least a portion of the high-melt filament to the film layer,
wherein the bonding layer does not pass through the braided, woven, or warp-knit layer;

wherein the jacket has abrasion resistance of at least 15% greater than the abrasion resistance of a jacket without a bonding layer.

20. A jacket for an elongated assembly, the jacket comprising:
a film layer;
a braided, woven, or warp-knit layer comprising a high-melt filament having a titer from 30 to 800 denier; and
a bonding layer between the braided, woven, or warp-knit layer and the film layer,
wherein the bonding layer is configured to adhere at least a portion of the high-melt filament to the film layer,
wherein the bonding layer does not pass through the braided, woven, or warp-knit layer;

wherein the jacket has a cut-through resistance higher than the cut-through resistance of a jacket without a bonding layer.

21. The jacket of claim 20 , wherein the jacket has a cut-through resistance at 23° C. of at least 10% greater than the cut-through resistance of the jacket without a bonding layer.

22. An elongated assembly comprising:
a core member comprising:
one or more cables; and
a surrounding layer for enclosing the one or more cables; and

a jacket surrounding the core member,
wherein the jacket comprises:
a film layer configured to surround the core member,
wherein the film layer has a first surface abutting the core member in a non-bonded relationship;

a braided, woven, or warp-knit layer comprising high-melt fibers having a titer from 30 to 800 denier; and
a bonding layer between the braided, woven, or warp-knit layer and a second surface of the film layer,
wherein the bonding layer is configured to adhere at least a portion of the high-melt fibers to the second surface of the film layer
wherein the bonding layer does not pass through the braided, woven, or warp-knit layer.

23. The elongated assembly of claim 22 , wherein the film layer and the surrounding layer are arranged in a non-bonded relationship.

24. The elongated assembly of claim 22 , wherein the one or more cables comprise optical fibers, conductors, coaxial cables, pairs or combinations thereof.

25. The elongated assembly of claim 22 , wherein the surrounding layer is an electromagnetic energy shielding layer.

26. The elongated assembly of claim 25 , wherein the shielding layer comprises a metal braided shield, an aluminized polyimide shield, a polyimide shield, or combinations thereof.

27. The elongated assembly of claim 22 , wherein the surrounding layer is a strength membrane.
