A glass fiber material is repeatedly immersed and dried in a sol solution obtained by hydrolyzing an aqueous solution consisting of a gel to form a gel coating of the intended thickness, and then heat-treated at 500 to 1500°C to form a coating. It's a method. This method is suitable for forming a relatively thin coating 1, for example, 0.1 to 1.5 .mu.m, and for cases where it is necessary to process the material glass fiber at a low temperature without substantially changing its physical properties.

得られる。(g) Effects of the invention According to this invention, a coating layer rich in chemical-resistant components is formed on the surface of the glass fiber where chemical resistance is required, and products with significantly improved chemical resistance are generally available. It can be obtained at a lower cost than chemical-resistant glass fiber. Furthermore, by adjusting the thickness of the coating layer, it is possible to produce a product that meets the required chemical resistance. Furthermore, since the glass fiber material does not contain a chemical-resistant component, it is possible to obtain a glass fiber that does not substantially change the physical and mechanical properties of the material itself.
