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