Summary: | A production method and production apparatus are provided for nanofiber aggregates produced and stretched into a fine-diameter fibrous shape by spraying a high-temperature, high-pressure gas from gas discharge ports into a polymer solution discharged from a solution discharge port. The nanofiber aggregates are collected into fine-diameter fibers in a high-temperature, high-pressure gas wind force by discharging secondary high-pressure air from high-pressure air blowing discharge ports in an intersecting pattern into a nanofiber flow during production and stretching. Further provided, as an effect, are nanofiber aggregates: having the characteristic that the distribution of fiber diameters thicker than the central fiber diameter and the distribution of fiber diameters thinner than the central fiber diameter are equal or better; and having excellent oil absorption capacity and oil keeping capacity. |
