Packing material and packing made of the same

A packing, fabricated by:

• cutting a flexible graphite sheet to a width of less than 5 mm;
• covering the surface of the flexible graphite sheet with fibers;
• impregnating the surface of the fibers with a surface treatment agent selected from graphite powder, silicone oil, rubber-based adhesive or polytetrafluoroethylene to form a knitting thread;
• and twisting or braiding the knitting thread.

A packing material comprising:

• at least one flexible graphite sheet cut to a width of less than 5 mm;
• and fibers covering the flexible graphite sheet, wherein:
• the flexible graphite sheet comprises a laminate of two to ten sheets;
• the covering fibers comprises a material selected from nickel-chromium-iron alloy, nickel-copper alloy, stainless steel, asbestos, ceramics fiber, glass fiber, carbon fiber, cotton, rayon, phenol, Aramid, polybenzimidazole, polytetrafluoroethylene, polyetherimide, polyphenylene sulfite or polyether etherketone;
• the covering fibers are knitted by any one of:
• conduit knitting and tubular weaving;
• the surface of the covering fibers is impregnated with surface treatment material selected from graphite powder, silicone oil, rubber-based adhesive or polytetrafluoroethylene;
• and
• the surface of the covering fibers is impregnated with any one of zinc and sodium nitrate as a corrosion preventive.
