Sliver knitted thermal substrate

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.
