Abstract

The present invention provides fabrics that have unique chemical, electrical, and thermal properties. The fabrics comprise layers of yarns woven together wherein the yarns further comprise carbon nanotube fibers. These carbon nanotube fibers may be either single-walled or multi-walled carbon nanotubes. The use of carbon nanotube fibers allows the fabrics to insulate, semi-conduct or super-conduct electrical charges. Additionally, the thermal properties of carbon nanotubes allow thermal energy to flow efficiently between the fabric and a heat sink or source. Additional yarns of materials other than carbon nanotubes can be integrated or woven into the fabric to provide other unique properties for the fabric. These fabrics can be layered to form unique garments or structures.

Claims (12)

1. A garment made of fabric, wherein said fabric comprises:

a first layer of yarns woven to form the fabric wherein said yarns comprise at least one carbon nanotube fiber and wherein said carbon nanotube fiber comprise single-walled carbon nanotubes and/or multi-walled carbon nanotubes; and

at least one additional layer of yarns woven together, wherein said first layer comprises yarns of superconductive carbon nanotube fibers that form a Faraday cage and wherein said at least one additional layer of yarns woven together comprise insulating carbon nanotube fibers.

2. The garment of claim 1 , wherein said carbon nanotube fibers comprise insulating, semiconducting, conducting and/or superconductive carbon nanotubes.

3. The garment of claim 1 , wherein said yarns comprise at least one fiber selected from the group consisting of wool, cotton, asbestos, nylon, synthetic and carbon nanotubes and wherein said carbon nanotube comprise insulating, semiconducting, conducting and/or superconductive carbon nanotubes.

4. The garment of claim 1 , wherein said first layer of yarns woven together exhibit the physical, electrical, mechanical, chemical or thermal properties of said at least one carbon nanotube fibers that comprise said yarns.

5. The garment of claim 1 , further comprising a tether electrically coupled to said first layer and wherein said tether shunts electricity flowing within said first layer to ground.

6. The garment of claim 1 , wherein said first layer comprises yarns of carbon nanotube fibers having a high thermal conductivity and wherein said at least one additional layer of yarns thermally insulate said first layer from a wearer.

7. The garment of claim 6 , further comprising a tether thermally coupled to said first layer and wherein said tether shunts thermal energy between said first layer and a heat-sink or heat-source.

8. The garment of claim 1 , wherein said garment comprises a glove, body suit or stockings.

9. The garment of claim 1 , wherein said first layer comprises tightly packed carbon nanotube fibers held together by Van der Walls' forces.

10. The garment of claim 9 , wherein said garment acts as barrier to objects larger than or equal to 1×10–9 meters.
