1. A coated glass fiber for reinforcing a rubber, comprising: (i) a glass fiber; (ii) a first coating layer covering the glass fiber, the first coating layer being prepared by a first process comprising the steps of: (a) dispersing a resorcinol-formaldehyde resin and a rubber latex in water to prepare a first coating solution; (b) applying the first coating solution to the glass fiber to form a first precursory layer; and (c) drying the first precursory layer into the first coating layer; and (iii) a second coating layer covering the first coating layer, the second coating layer being prepared by a second process comprising the steps of: (d) dispersing bisallylnadiimide, a rubber elastomer, a vulcanizing agent, and an inorganic filler in an organic solvent to prepare a second coating solution; (e) applying the second coating solution to the first coating layer to form a second precursory layer; and (f) drying the second precursory layer into the second coating layer.
