PROBLEM TO BE SOLVED: To provide a polyester staple fiber scarcely causing a change in feeling of easily slipping even after washed, by keeping the feeling of easily slipping excellent as well, further scarcely causing entanglement of the fiber of a product, such as a padded mattress after processed, after the product is washed, to say nothing of scarcely causing the entanglement before washed, and therefore optimal for a wadding raw material. SOLUTION: This polyester fiber is coated with a finish which is resinified on a surface of the fiber, wherein the finish contains [A] a carboxy-modified silicone, [B] an amino-modified silicone, and [C] an aminoalkoxysilane as essential components. The polyester fiber is obtained by crimping a polyester fiber, applying the finish to the fiber in an amount of 0.4-0.6 wt%, heat-treating the fiber at 150-160°C, and applying an antistatic agent to the fiber in an amount of 0.1-0.3 wt%.
