Abstract: In a method producing a molded article of a composite resin containing base resin and fibers, the composite resin containing a fibrous filler in the base resin and the fibrous filler including natural fibers with a fibrillated part on each end of the fibrous filler in a fiber length direction, the base resin and the fibrous filler are charged into a melt-kneading device. The base resin is melted and the molten base resin and the fibrous filler are kneaded in the melt-kneading device, thereby fibrillating only the ends of the fibrous filler. The obtained composite resin is discharged from the melt-kneading device and formed into a pellet shape, with the molded article of the composite resin produced by molding the pellets.

Abstract: For a fiber compound resin composition, a melt-kneading process is performed together with a base resin 1, a dispersant, etc. without performing a pretreatment through wet dispersion for the purpose of defibration treatment and modification treatment of a fibrous filler 2. As a result, each fiber of the fibrous filler 2 is defibrated from end portions in a fiber length direction, while a dispersant component put in at the same time is more selectively adsorbed to defibrated portions 3 at the end portions defibrated and increased in surface area. As a result, hydrophobization of the defibrated portions 3 is promoted as compared to a non-defibrated portion 4, so that a difference in hydrophobicity is formed in the fiber length direction of the fibrous filler 2. Therefore, even when the fibrous filler 2 is added in large amount, a melt viscosity during molding may be lowered without reducing a strength of a molded article.
