A paper-like polyester fiber sheet having enhanced mechanical strength, opaqueness, and resistance to permeation of liquids, gases, and bacteria and a soft touch, including polyester short fibers each having a thickness of 0.1 to 15 denier and a length of 3 to 25 mm and provided with a flat cross-sectional profile having a degree of flatness (a ratio in length of a major axis to a minor axis of the profile) of 2.5 or more. The polyester short fibers preferably exhibited an irreversible spontaneous elongation in hot water at 90°C. |
