IMMERSION LIQUID, PRODUCTION METHOD THEREOF, AND PRODUCTION METHOD OF GLASS FIBER WOVEN FABRIC HAVING POLYMER COATING FILM

摘要

PROBLEM TO BE SOLVED: To provide an immersion liquid for improving bond strength of glass fiber woven fabrics, to provide a production method thereof, and to provide a production method of glass fiber fabrics having a polymer coating film. SOLUTION: There is provided a production method including: (a) the step S23 for immersing a glass fiber woven fabric in an immersion liquid containing a fluorocarbon polymer powder and a fluorinated silicone graft copolymer; (b) the step S24 for drying the immersed glass fiber woven fabric to adhere a connecting film on the surface of the glass fiber woven fabric; (c) the step S25 for covering with a fluorocarbon resin thin film the connecting film adhered on the surface of the glass fiber woven fabric; and (d) the step S26 for thermocompression bonding of the fluorocarbon resin thin film with the connecting film of the glass fiber woven fabric.
