PROBLEM TO BE SOLVED: To provide a method of simply and efficiently producing, at a low cost, polyethylene staple fibers which are hardly charged with electrostatic electricity, have excellent dispersibility, and are especially suitable for being compounded with rubbers. SOLUTION: This method of producing the polyethylene staple fibers is characterized by melt-spinning polyethylene to form the undrawn fibers, heating and drawing the undrawn fibers, simultaneously imparting a small amount of an oiling agent to the polyethylene fibers formed by the heating and drawing treatments by the use of an oiling agent-imparting means, and then cutting the oiling agent-imparted polyethylene fibers. A mode that the oiling agent- imparting means is a coating roller, a mode that the adhesion amount of the oiling agent is 3 to 35 wt.% based on the total amount, a mode that the oiling agent contains an oil and water in amounts of 1.5 to 33.5 wt.% and 1.5 to 33.5 wt.%, respectively, based on the polyethylene, and so on, are preferable. |
