PURPOSE:To obtain a fixing agent for preventing fray of woven fabric of glass fiber having firm adhesion, not to make warp at the end fray, having preventing effect on fray by sealing a fray preventing fixing agent to both selvadge parts of woven fabric of glass fiber. CONSTITUTION:Both selvage parts of woven fabric of glass fiber in fixed width are coated with 2-10wt.% of a fray preventing fixing agent such as a water- based urethane resin based on weight of part to be coated of the woven fabric of glass fiber and the fixing agent is cured to give woven fabric of glass fiber having high bond strength, a flexible coating film, excellent solvent resistance and improved fray preventing effect. By this method, thickness of the part to be coated is not changed and uniform and the water-based urethane resin is advantageously used. This fray preventing fixing agent is suitable as a fixing agent for preventing selvadge fray of glass fiber woven by an air jetting weaving machine useful for copper-clad laminate. |
