WIPO Patent Application WO/2004/029353

Kind Code:

A1

Abstract:

A carbonaceous fiber fabric composed of carbonaceous fiber yarns, characterized in that it has both end portions having been subjected to a treatment for preventing the yarn from being frayed, preferably the side end portions are cut so as to have a saw tooth or wave tooth shape wherein one tooth unit has a ratio (t/l) of the length in the transverse direction (t) to the length in the longitudinal direction (l) of 0.2 to 5, to thereby prevent the yarn from being frayed. The carbonaceous fiber fabric is suppressed in the occurrence of the fray of a yarn in end portions due to repeated rewinding and winding operations.
