    The purpose of this study was to evaluate the suitability of a high-strength polyester fabric as a material for air leisure sports, by comparing its physical properties with those of commercially available nylon fabric. In addition, the weatherability during the winter season outdoor exposure test was compared, for evaluation in an actual operating environment, and the degradation behavior after outdoor exposure was examined. The tensile strength, elongation, and tear strength of the polyester fabric having a ripstop structure were found to be sufficient to substitute nylon fabric, which has been used for air leisure sports. Furthermore, the weather resistance test by outdoor exposure indicated that the polyester has excellent weatherability, compared with that of nylon. Compared with that in outdoor weathering, the accelerated weathering of nylon and polyester fabrics leads to a more rapid decrease in the elongation and tensile strength. SEM, spectrophotometry, FT-IR, XRD, and TG analyses showed that the polyester was less degraded than the nylon fabric.
