ABSTRACT:
The present invention provides a process for producing a polyamide resin composition, comprising the steps of: impregnating a molten polyamide resin into glass fiber rovings; taking off the polyamide-impregnated glass fiber rovings during twisting thereof to provide a strand; and pelletizing the strand to provide a resin composition, wherein a melt viscosity of the polyamide resin is set to fall within a particular range. According to the present invention, there can be provided a process for producing a glass fiber-reinforced polyamide resin composition excellent in the impregnation of the resin into the glass fiber rovings and capable of offering a molding excellent in mechanical strength and color tone.
