PROBLEM TO BE SOLVED: To obtain a processing agent for fibrous materials not requiring heat treatment after processing even when using a high-melting hydrophobic resin by dispersing in water containing a specific dispersion stabilizing agent a hydrophobic resin together with an organic solvent able to dissolve the resin. SOLUTION: This processing agent for fibrous materials is obtained by dispersing (A) a hydrophobic resin (e.g. polyethylene wax) such as a thermoplastic resin, a natural resin, rubbers or waxes and (B) an organic solvent (e.g. ethyl acetate) able to dissolve the resin in a weight ratio of (80:20) to (30:70) in water containing (C) a dispersion stabilizing agent comprising (i) at least one selected from the group consisting of a cationic polymer (e.g. a dimethylaminoethyl methacrylate-acrylamide copolymer) having a cationization degree of >=30% and an average molecular weight of >=300,000 and an anionic polymer (e.g. an acrylamide-methacrylic acid copolymer) having an average molecular weight of >=1,000,000, and/or (ii) polyvinyl alcohol having a cationization degree of 70-90% and an average molecular weight of 50,000-300,000 as at least one essential ingredient.
