    Abstract: A carbon fiber spun yarn, which is a spun yarn of a carbon fiber that has an average (002)-interlayer spacing of 0.340-0.380 nm as measured by X-ray diffraction method, has a specific gravity of 1.55-1.80 as measured by a density gradient tube method, a hydrogen-to carbon atomic ratio (H/C) as measured by elementary analysis of at most 0.1 and contains 3-30 wt. % of carbon fiber having a fiber length of at least 150 mm, wherein the spun yarn has a weight per 1000 m (tex) of 30-150 g, a number of primary twist of 50-400 turns/m and a tensile strength of at least 0.15 N/tex. The carbon fiber spun yarn may be woven to provide a carbon fiber woven fabric suitable as a gas diffuser (electroconductive substrate) of a solid polymer electrolyte fuel cell.

    IPC: D01G27/00

    CPC classification number: D01G15/68

    Abstract: A pitch-based carbon fiber sliver providing a high-strength carbon fiber spun yarn is efficiently produced by providing a pitch-based carbon fiber mat comprising a mass of piled-up pitch-based carbon fibers of which fiber extension directions are aligned preferentially in one direction; and directly subjecting the carbon fiber mat to drawing and carding by means of a carding machine while moving the mat in said one preferential alignment direction. The thus-obtained carbon fiber sliver is drawn and twisted to produce a pitch-based carbon fiber spun yarn containing at least 3 wt. % of fibers having a fiber length of at least 150 mm, a number of primary twist of 50-400 turns/m and a tensile strength of at least 0.10 N/tex.
