Abstract: A method for producing ultrafine fibers of the present invention includes forming an electric field between an discharging nozzle from which a raw resin is discharged and a charging electrode which is disposed apart from the discharging nozzle, and supplying the raw resin which has been heated and melted into the electric field from the discharging nozzle to spin the raw resin. The raw resin is a resin mixture which contains a resin having a melting point and an additive, and satisfies a relation (I) below: A/B≥1.0×102  (I) wherein A represents the absolute value (Ω) of electrical impedance of the raw resin at 50° C., and B represents the absolute value (Ω) of electrical impedance of the raw resin at a temperature 50° C. higher than a melting point of the raw resin.

Abstract: A polyester resin composition containing a polyester resin, and a fine cellulose fiber composite having an average fiber diameter of from 0.1 to 200 nm, wherein the fine cellulose fiber composite contains fine cellulose fibers and hydrocarbon groups being connected thereto via an amide bond. The polyester resin composition of the present invention can be worked into a molded article by thermoforming or injection-molding, and is suitably used for various industrial applications, such as daily sundries, household electric appliance parts, packaging materials for household electric appliance parts, and automobile parts. In addition, the fine cellulose fiber composite has high dispersibility against various resins and can exhibit thickening effects, so that it is suitable as various thickeners or the like.
