Abstract
A thermal insulation material for articles of clothing, the material including fibers for providing thermal insulation and fibers for providing a stable structure for the material.
Claims36
A thermal insulation material for articles of clothing, the insulation material comprising:
- a first layer of fabric material for disposition adjacent the body of a wearer;
- a second layer of material adjacent to said first layer of material, said second layer of material comprising electrically conductive nanofibers;
- a third layer of material adjacent to said second layer of material, said third layer of material comprising regular fibers having diameters of greater than one micron;
- and
- a fourth layer of fabric material adjacent said third layer of material;
- wherein said second layer of material, when subject to radiated heat from the body of the wearer, refracts a major portion of the radiated heat back to the body of the wearer;
- and
- wherein said third layer of material provides structural strength to the insulation material.
