Abstract
The present invention relates to gland packing materials made from expansive graphite, gland packing made from expansive graphite made from the materials, and a producing method of gland packing made from expansive graphite; braiding thread is a filamentose with winding or twisting a strip laminated sheet that a bundle of sprit fiber is laminated and unified through an adhesive layer so as to be a reinforcing material, and a cord body is constructed by braiding the braiding thread, then a packing is constructed by pressure forming this cord body.
Claims4
A braiding yarn for use in a gland packing comprising a strip laminated sheet, said strip laminated sheet having an expansive graphite sheet and a bundle of opened carbon multifilaments which are adhered to the expansive graphite sheet through use of an adhesive layer,
- wherein said strip laminated sheet is twisted so as to form a first filamentous yarn structure having said open carbon multifilaments positioned on the outer periphery of said first filamentous yarn structured.
