CARBONACEOUS FIBER FABRIC, ROLL OF CARBONACEOUS FIBER FABRIC, GAS DIFFUSION LAYER MATERIAL FOR SOLID POLYMER FUEL CELL, METHOD FOR PRODUCTION OF CARBONACEOUS FIBER FABRIC, AND METHOD FOR PRODUCTION OF SOLID POLYMER FUEL CELL
An objective of the invention is to suppress a loosening of strands at both ends of a carbonic fiber woven fabric which is generated as a result of a repetitive rolling and unrolling. ??The present invention is to conduct an anti-loosening treatment of carbonic fiber strand by means of cutting both ends of a carbonic fiber woven fabric consisting of carbonic fiber strand into the serrate or wavy form so that the ratio (t/l) of the transverse length (t) of the woven fabric to the longitudinal length (l) of the woven fabric becomes 0.2 to 5.
