A method for producing a woven fabric comprises weaving fibers in a warp direction and a weft direction to form a fabric having a top surface and a bottom surface, wherein the warp fibers and weft fibers each comprises one or more filaments of a synthetic polymer having substantially uniform cross-sectional composition. At least a portion of the filaments in the fibers on the top and/or bottom surface of the fabric are then fused together in the presence of a heat transfer liquid or vapor added during the fusing step or added in a prior step of the fabric production process and retained by the filaments. The fusing step produces a treated fabric having a tensile strength in both the warp and weft directions of 1000 N or greater and having, in the absence of any coating, a static air permeability (SAP) of 3 l/dm2/min or lower.
