Thermal barrier fabric

A garment fabric for conservation of body heat of a wearer, the fabric comprising:

• opposed layers of impermeable material joined together to define at least one closed compartment, said opposed layers including at least one layer comprising a cloth material coated with a fusible silicone;
• a spacer material disposed within the compartment between said layers of impermeable material, said spacer material:
• being substantially coextensive with non-joined portions of said opposed layers of impermeable material;
• having a thickness greater than a thickness of a combination of all layers of the fabric;
• being of a material exhibiting move void space than structural space;
• and
• being bendable and compressible, but having sufficient resistance to compression to maintain separation between said opposed layers;
• wherein
• the compartment being under a vacuum, said compartment having a valve for drawing the vacuum in the compartment.

A heat barrier material for conservation of body heat of a Wearer, the barrier comprising:

• an inner impermeable material layer;
• an outer impermeable material layer;
• a spacer material disposed between said inner and outer impermeable material layers, said spacer material exhibiting more void space than structural space, and being of a thickness greater than a thickness of a combination of all layers of the fabric;
• and
• a reflective layer of material disposed between said spacer and a selected one of said inner impermeable material layer and said outer impermeable material layer;
• said inner and outer impermeable material layers including at least one layer comprising a cloth material coated with a fusible silicone, and
• said inner and outer impermeable material layers being bound to each other along portions thereof outbound of said spacer material and said reflective layer of material to define a closed compartment;
• wherein
• the compartment being under a vacuum, said compartment having a valve for drawing the vacuum in the compartment;
• whereby
• said reflective layer of material reflects body heat back toward a wearer of the barrier material and the vacuum substantially prevents heat transfer through the compartment.

A fabric for obstructing flow of heat therethrough toward a wearer of the fabric, the fabric comprising:

• an inner impermeable material layer;
• an outer impermeable layer of non-melting material;
• a spacer material disposed between said inner and outer impermeable material layers, said spacer material exhibiting more void space than structural space, and being bendable and compressible, but having sufficient resistance to compression to maintain separation between said inner and outer impermeable material layers, said spacer material being of a thickness greater than a thickness of a combination of all layers of the fabric;
• and
• a reflective layer consisting of mylar disposed between said spacer and a selected one of said inner impermeable material layer and said outer impermeable material layer;
• said inner and outer impermeable material layers including at least one layer comprising a cloth material coated with a fusible silicone, and said inner and outer impermeable material layers being bound to each other along portions thereof outbound of said spacer material and said reflective layer of material to define a closed compartment;
• wherein
• the compartment being under a vacuum, said compartment having a valve for drawing the vacuum in the compartment;
• whereby
• said reflective layer reflects heat back toward a source of heat and the vacuum substantially reduces heat transfer through the compartment toward the wearer.

A thermal barrier fabric for enclosures, the fabric being adapted to provide thermal shielding of contents of the enclosures, the fabric comprising:

• an inner impermeable material layer;
• an outer impermeable layer;
• a spacer material disposed between said inner and outer impermeable material layers, said spacer material exhibiting more void space than structural space, and being bendable and compressible, but having sufficient resistance to compression to maintain separation between said inner and outer impermeable material layers, said spacer material being of a thickness greater than a thickness of a combination of all layers of the fabric;
• and
• a reflective layer consisting of mylar disposed between said spacer and a selected one of said inner impermeable material layer and said outer impermeable material layer;
• said inner and outer impermeable material layers being bound to each other along portions thereof outbound of said spacer material and said reflective layer to define a closed compartment, said inner and outer impermeable material layers including at least one layer comprising a cloth material coated with a fusible silicone;
• wherein
• the compartment being under a vacuum, said compartment having a valve for drawing the vacuum in the compartment;
• whereby
• said reflective layer reflects thermal energy back toward a source thereof and the vacuum substantially prevents thermal energy transfer through the compartment.
