Abstract
An insulating liner for an article of clothing includes a first layer, a second layer attached to the first layer, and an insulating layer sealed between the first and second layers, wherein the insulating layer is composed of an aerogel material. The first and second layers can be a PVC foam hermetically sealed about the aerogel material by welding. In a preferred embodiment, the insulating liner is a shoe liner that includes a polyester wearing material adhered to the top layer of PVC foam. A method of forming the insulating liner is also provided.
Claims21
An insulating liner for an article of clothing, comprising:
- a first layer;
- a second layer, said first and second layers each having a thickness of at least 1.5 mm;
- an insulating layer sealed between said first and second layers, wherein said insulating layer comprises an aerogel material in the form of an aerogel carried and supported by a flexible polymeric fibrous material that exhibits resiliency and bulk recovery;
- wherein, said first and second layers are impermeable to air and are hermetically sealed together about the periphery of said insulating layer.
A shoe liner, comprising:
- a first PVC foam layer;
- a second PVC foam layer;
- a wearing material attached to an outer surface of said second layer;
- and
- an aerogel material hermetically sealed between said first and second layers, wherein said aerogel material comprises an aerogel carried by a flexible fibrous substrate, wherein said first and second foam layers and said flexible fibrous substrate together form a compressible structure for said shoe liner that provides cushioning in use.
An insulating liner for an article of clothing, comprising:
- a first layer;
- a second layer;
- an insulating layer that includes:
- a fibrous carrier material in the form of a sheet cut to fit between the first and second layers;
- and
- an aerogel dispersed throughout the fibrous carrier material such that the aerogel is impregnated in and supported by the carrier material;
- wherein said insulating layer is sealed between said first and second layers;
- and
- wherein said insulating layer comprises a compressible layer that exhibits resiliency and bulk recovery;
- wherein, said first and second layers are impermeable to air and are hermetically sealed together about the periphery of said insulating layer.
