Claims
- 1. A gasket structure for shielding against electromagnetic and radio frequency interference, said gasket structure comprising:a core; a first tubular layer formed from a hot melt yarn and having a length and a transverse dimension, said first tubular layer circumferentially and longitudinally enveloping said core; and a second tubular structure formed from a conductive yarn and having a length and a transverse dimension, said second tubular structure being disposed over at least a portion of said first tubular layer; wherein said hot melt yarn forming said first tubular layer adheres said second tubular structure to said core at a plurality of contact points such that fraying of said gasket structure is substantially prevented.
- 2. The gasket structure according to claim 1, wherein said core includes a neoprene sponge.
- 3. The gasket structure according to claim 1, wherein said conductive yarn includes a nylon yarn plated with silver.
- 4. The gasket structure according to claim 1, wherein said first tubular layer is knitted from said hot melt yarn.
- 5. The gasket structure according to claim 4, wherein said knitted first tubular layer is formed by circular knitting.
- 6. The gasket structure according to claim 1, wherein said second tubular structure is knotted from said conductive yarn.
- 7. The gasket structure according to claim 6, wherein said knitted second tubular structure is formed by circular knitting.
- 8. The gasket structure according to claim 7, wherein said conductive yarn includes a nylon yarn plated with tin.
- 9. The gasket structure according to claim 6, wherein said conductive yarn includes a nylon yarn plated with aluminum.
- 10. The gasket structure according to claim 1, wherein said core includes an elastomer foam.
