(57) [Abstract] [Problem] Excellent mechanical stability, dilution stability, compounding stability, and stability over time, does not generate oil spots on fiber materials, and has durable water repellency and waterproofness. , A fiber treatment agent capable of imparting flexibility, smoothness, wrinkle resistance, and compression recovery. SOLUTION: The fiber treating agent of the present invention comprises an organosiloxane (I), a graft crossing agent (II), (I) and (II). Polyorganosiloxane polymer (III) obtained by polycondensation in a proportion of 0.02 to 20% by weight with respect to the total amount of components (III) 1 to In the presence of 90 parts by weight (solid content) of the aqueous dispersion, (a) an alkyl group (meth) acrylic acid alkyl ester having 1 to 10 carbon atoms (19.5 to 99.5% by weight), (b) an ethylenically unsaturated carboxylic acid Polyorganosiloxane emulsion obtained by polymerizing 99 to 10 parts by weight of a monomer component (IV) consisting of 0.5 to 50% by weight of an acid and 0 to 80% of another copolymerizable monomer (IV). Is the main ingredient. |
