Abstract

The present invention provides a glass direct roving which enables the achievement of good glass filament-reinforced thermoplastic resin pellet productivity, while being capable of achieving a good balance between excellent spinnability and good strength of a glass fiber-reinforced resin molded article that is produced using glass filament-reinforced thermoplastic resin pellets. This glass direct roving is configured by bundling a plurality of glass filaments; the filament diameters D of the glass filaments are within the range of from 17.5 μm to 21.5 μm; the number F of the bundled glass filaments is within the range of from 3,000 to 7,000; the mass of this glass direct roving is within the range of from 2,450 tex to 4,000 tex; the ignition loss L of this glass direct roving is within the range of from 0.03% to 0.90%; and the above-described D, F and L satisfy formula (1).

Abstract

The present invention provides a surface-treated glass cloth which is provided with excellent insulation reliability, while having high productivity. A surface-treated glass cloth according to the present invention comprises a surface treatment layer in the surface. The surface treatment layer contains: a first silane coupling agent which contains at least one amine that is selected from the group consisting of primary amines, secondary amines and tertiary amines, while containing no quaternary ammonium cations; a second silane coupling agent which contains at least one quaternary ammonium cation; an organic acid; and a surfactant. The total content of the first silane coupling agent and the second silane coupling agent is from 0.05% by mass to 1.20% by mass relative to the total amount of the surface-treated glass cloth; the ratio of the molar content of the first silane coupling agent to the molar content of the second silane coupling agent is from 1.1 to 10.0; and the content of the organic acid is from 50 ppm to 300 ppm relative to the total amount of the surface-treated glass cloth.
