Abstract

The invention provides a substrate for inhibiting heat transfer. The substrate includes a textile base layer formed with filamentary members. The substrate also includes a sliver layer having a plurality of staple fibers interlaced with the filamentary members of the textile base layer. The staple fibers of the sliver layer are oriented substantially perpendicular to the base layer. The substrate also includes at least one reflective layer attached to one of the base layer and the sliver layer.

Claims

1. A substrate for protecting a component from one of heat transfer and vibration transfer comprising:

a textile base layer formed with filamentary members; and

a sliver layer having a first plurality of staple fibers interlaced with said filamentary members of said textile base layer and oriented substantially perpendicular to said textile base layer.

2. A substrate for inhibiting heat transfer comprising:

a textile base layer formed with filamentary members;

a sliver layer having a first plurality of staple fibers interlaced with said filamentary members of said textile base layer and oriented substantially perpendicular to said textile base layer; and

at least one reflective layer attached to one of said textile base layer and said sliver layer.

3. The substrate according to claim 2 wherein said at least one reflective layer is attached to said first plurality of staple fibers.

4. The substrate according to claim 2 wherein said at least one reflective layer is spaced from said first plurality of staple fibers.

5. The substrate according to claim 2 wherein said first reflective layer includes a metallic foil.

6. The substrate according to claim 2 wherein said at least one reflective layer includes a first reflective layer attached to said first plurality of staple fibers and a second reflective layer attached to said textile base layer.

7. The substrate according to claim 2 wherein said first plurality of staple fibers of said sliver layer have a denier between about 4 and about 10.

8. The substrate according to claim 2 wherein said first plurality of staple fibers of said sliver layer are further defined as being between about one and about two inches long.

9. The substrate according to claim 2 wherein said first plurality of staple fibers are formed, at least in part, from polyester.

10. The substrate of claim 2 wherein said sliver layer further comprises:

a second plurality of staple captured by said textile base layer.

11. The substrate of claim 2 wherein said first plurality of staple fibers are formed from different materials.

12. The substrate of claim 2 wherein at least some of said first plurality of staple fibers are heat shrinkable.

13. The substrate of claim 12 wherein less than all of said first plurality of staple fibers are heat shrinkable.

14. The substrate according to claim 2 wherein said filamentary members are formed from material selected from a group comprising glass, aramids, and polyester.

15. The substrate according to claim 2 wherein said filamentary members comprise multifilament yarns.

16. The substrate according to claim 2 wherein said textile base layer further comprises:

a plurality of monofilaments laid in with said filamentary members, and being biasable into a predetermined shape for forming said textile base layer.

17. The substrate according to claim 2 wherein said textile base layer has a tubular shape.

18. A method for inhibiting heat transfer comprising:

forming a textile base layer with filamentary members;

interlacing a first plurality of staple fibers of a sliver layer with the filamentary members of said textile base layer oriented substantially perpendicular to the textile base layer; and

attaching at least one reflective layer to one of the textile base layer and the sliver layer.

19. The method of claim 18 further comprising the step of:

defining a density gradient between free ends of the staple fibers and the textile base layer.

20. The method of claim 18 further comprising the step of:

resiliently biasing the textile base layer into a predetermined shape.

21. The method of claim 18 further comprising the step of:

shrinking less than all the staple fibers after formation of the sliver layer.
