Abstract: The present invention relates to a polyester staple yarn for a wet non-woven fabric, and a wet non-woven fabric including the same, wherein the polyester staple yarn is manufactured by using a polymerization catalyst including a titanium-based compound. The polyester staple yarn is superb in terms of dispersibility due to the remarkably low defect formation thereof, and thus, the present invention can provide a wet non-woven fabric having excellent mechanical strength, and a manufacturing method therefor.
