6 Claims

1. A composite yarn fabric, obtained by performing 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,

wherein the inorganic multifilament yarns have a mass in a range of 10 to 65 tex,

each of the inorganic multifilament yarns is a bundle of only inorganic monofilaments,

the monofilaments constituting the inorganic multifilament yarns have a fiber diameter in a range of 6.6 to 9.5 μm,

a melt flow rate of a thermoplastic resin constituting the thermoplastic resin yarns is in a range of 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 in a range of 40 to 90% by mass.
