ABSTRACT:
A raveling-preventing agent for a glass fiber woven fabric, which contains as essential components a reaction product from an epoxy resin having an epoxy equivalent of 150 to 1,000 and a molecular weight of 500 to 2,000 and a hydroxyl group-containing amine compound, and an isocyanate curing agent. The raveling-preventing agent firmly binds glass fibers together and prevents the raveling of edge-forming warp yarns when applied to sectioned marginal portions of a glass fiber woven fabric. Further it is free from swelling in a solvent used in a thermosetting resin varnish.
