Claims
- 1. A gasket for shielding from electromagnetic emissions (EMI), and exhibiting excellent characteristics of recovery, bending, and tangential compression, said gasket comprising:
- a knitted tubular core of monofilament synthetic polymer yarns; and
- a conductive sheath over said tubular knitted core, said sheath being sufficiently conductive to provide shielding from electromagnetic interference.
- 2. A gasket according to claim 1 wherein said conductive sheath comprises a fabric selected from the group consisting of woven fabrics, weft knitted fabrics and warp knitted fabrics.
- 3. A gasket according to claim 2 wherein said conductive sheath comprises conductive yarns.
- 4. A gasket according to claim 3 wherein said conductive yarns comprise metal yarns.
- 5. A gasket according to claim 3 wherein said conductive yarns comprise nonmetallic yarns in which selected yarns are coated with metal.
- 6. A gasket according to claim 1 wherein said knitted core comprises synthetic polymer yarns selected from the group consisting of: polyester, nylon, polyethylene, polypropylene, and combinations thereof.
- 7. A gasket according to claim 1 wherein said monofilament yarns comprise highly oriented, high modulus yarns.
- 8. A gasket for shielding from electromagnetic emissions (EMI), and exhibiting excellent characteristics of recovery, bending, and tangential compression, said gasket comprising:
- a knitted core of monofilament synthetic polymer yarns; and
- a circular warp knitted sheath over said monofilament knitted core, said sheath being sufficiently conductive to provide shielding from electromagnetic interference over a wide range of frequencies.
- 9. A gasket according to claim 8 wherein said sheath is longitudinally stabilized with an interlaced yarn.
- 10. A gasket according to claim 9 wherein said interlaced yarn is a conductive yarn.
- 11. A gasket according to claim 8 wherein said sheath is stabilized by two interlaced yarns that form at least one substantially flat side of said gasket.
- 12. A gasket according to claim 8 wherein said sheath is stabilized by three interlaced yarns that form a substantially triangular cross-section gasket.
- 13. A gasket according to claim 8 wherein said sheath is stabilized by four interlaced yarns that form a substantially square cross-section gasket.
- 14. A gasket according to claim 8 wherein said knitted sheath comprises conductive yarns.
- 15. A gasket according to claim 14 wherein said conductive yarns comprise nonmetallic yarns in which selected yarns are coated with metal.
- 16. A gasket according to claim 14 wherein said conductive yarns comprise metal yarns.
- 17. A gasket according to claim 8 wherein said knitted sheath comprises conductive yarns and polymeric yarns.
- 18. A gasket according to claim 8 wherein said knitted core comprises highly oriented, high modulus yarns.
- 19. A gasket according to claim 17 wherein said polymeric yarns in said knitted sheath comprise monofilament yarns.
- 20. A gasket according to claim 8 wherein said core is warp knitted.
- 21. A gasket according to claim 8 wherein said core is weft knitted.
- 22. A gasket according to claim 8 wherein said conductive sheath further comprises an adhesive for securing said sheath to said core, and for preventing said gasket from fraying when cut to specific lengths.
