Abstract

An aramid fabric having excellent adhesion to a polyurethane matrix resin and excellent tensile strength is produced by the method including the steps of: (i) weaving a basket-structured aramid fabric by using aramid yarns as warp and weft yarns; and then (ii) dipping the woven aramid fabric in a sizing agent solution consisting of an aqueous polyurethane resin as a sizing agent and water, followed by squeezing and drying. In the present disclosure, the sizing agent is applied to the woven aramid fabric, thereby effectively preventing the deterioration in weaving efficiency. Further, the aramid fabric is woven in a basket weave, and thus the compactness of the aramid fabric is lowered and the wetting property of the aramid fabric with the polyurethane matrix resin is improved.
