PROBLEM TO BE SOLVED: To provide a polybenzasol fiber textile usable for application requiring not only stability to external stress, heat resistance and flame retardancy, but also uniformity of the textile. SOLUTION: The polybenzasol fiber textile is obtained by using a polybenzazole fiber in which the projection rate (%) of each cross section of each monofilament in the polybenzazole multifilament is at least 75% as warp and/or weft yarns. In another aspect, the polybenzazole fiber textile is obtained by using the polybenzazole monofilament fiber in which the fiber cross section is the projecting cross section as the warp and/or weft yarn. The projection rate is expressed by the formulation: the projection rate (%) = ä(the number of fibers having the projecting cross sections)/(the number of the component multifilaments)}×100.
