PURPOSE:To produce a glass fiber excellent in chemical resistance such as alkaline resistance and acid resistance and exhibiting an excellent dispersibility in a wet type process for making a non-woven fabric in spite of its low-cost raw material composed of E glass fiber. CONSTITUTION:This glass fiber is coated with a fiber size containing an epoxy resin, a curing agent for the epoxy resin, an epoxy silane-containing silane coupling agent and a nonionic surfactant such as an ethylene oxide addition product of bisphenol A or a polyethylene glycol fatty acid ester. |
