Abstract
A composite yarn fabric which can be suitably used as a material of a fiber-reinforced resin molded article is provided. The composite yarn fabric is obtained by weaving using composite yarns as at least one of the warp or the weft, the composite yarns obtained by doubling and twisting inorganic multifilament yarns and thermoplastic resin yarns. The inorganic multifilament yarns have a mass of 10 to 65 tex, monofilaments constituting the inorganic multifilament yarns have a fiber diameter of 6.6 to 9.5 μm, a melt flow rate of a thermoplastic resin constituting the thermoplastic resin yarns is 34 to 100 g/10 minutes, and a ratio of a mass of the inorganic multifilament yarns to a total mass of the composite yarns is 40 to 90% by mass.
