Abstract
An insulating liner for an article of clothing includes an insulating layer including an aerogel material and having opposite sides with passages extending therebetween, and a cover encapsulating the insulating layer. The cover includes vent holes aligned with the passages of the insulating layer, and has portions that extend into the passages of the insulating layer from the opposite sides of the insulating layer, with the portions having vent holes therethrough and being sealed about the periphery of the vent holes. A valve may be provided with the liner to allow gas to be withdrawn or expelled from the liner. Methods of forming the insulating liner(s) are also provided.

An insulating liner for an article of clothing, comprising:
- an insulating layer comprising a dust generating aerogel composite that includes a fibrous substrate carrying an aerogel material, said insulating layer having opposite sides with a plurality of passages extending therebetween;
- and
- a cover hermetically encapsulating said insulating layer and including a plurality of vent holes aligned with said plurality of passages of said insulating layer, said cover having portions that extend into said plurality of passages of said insulating layer from said opposite sides of said insulating layer, with said portions having vent holes therethrough and being sealed about the periphery of said vent holes.
An insulating liner for an article of clothing comprising:
- an insulating layer comprising a dust generating aerogel composite that includes a fibrous substrate carrying an aerogel material, said insulating layer having opposite sides with a plurality of passages extending therebetween;
- and
- a cover hermetically encapsulating said insulating layer and including a valve to allow gas within said liner to pass therethrough.
A method of forming an insulating liner for an article of clothing, comprising the steps of:
- providing at least one insulating layer comprising a dust generating aerogel composite that includes a fibrous substrate carrying an aerogel material, said aerogel composite having a plurality of passages therethrough;
- providing first and second sheets of an impermeable polymeric material;
- encapsulating said at least one insulating layer between said first and second sheets;
- cutting said first and second sheets to a desired shape;
- and
- forming a plurality of vent holes through said first and second sheets at said plurality of passages.
A method of forming an insulating liner for an article of clothing, comprising the steps of:
- providing at least one insulating layer comprising a dust generating aerogel composite that includes a fibrous substrate carrying an aerogel material, said aerogel composite having a plurality of passages therethrough;
- providing a cover of an impermeable polymeric material;
- encapsulating said at least one insulating layer within said cover;
- cutting said cover to a desired shape;
- providing a valve in said cover;
- and
- displacing gas from within said insulating liner through said valve to reduce gas pressure therein.
