Abstract
A production process for producing a glass fiber fabric that has good smoothness and is excellent in resin impregnation property is provided wherein glass fiber yarns are woven to obtain a glass fiber fabric.
Claims5
A process for production of a glass fiber fabric having silica microparticles adhered thereon in which silica microparticles are attached or fused on glass filament surfaces of a glass fiber fabric to adhere the silica microparticles, comprising:
- an attachment step of immersing the glass fiber fabric in which a sizing agent is attached on the glass filaments, in an aqueous dispersion of silica microparticles to attach the silica microparticles on the glass filament surfaces of the glass fiber fabric;
- a fiber-opening step of providing a fiber-opening treatment to the glass fiber fabric on which the silica microparticles are attached by the attachment step;
- and
- a heating step of heat-treating the glass fiber fabric to which the fiber-opening treatment is provided by the fiber-opening step, to fuse some or all of the silica microparticles attached by the attachment step, on the glass filament surfaces of the glass fiber fabric.
