WATER-AND-OIL REPELLANT COMPOSITION FUNCTIONAL TEXTILE PRODUCT AND PRODUCTION METHOD FOR FUNCTIONAL TEXTILE PRODUCT

摘要

The water and oil repellent composition of the present invention comprises a pyrazole block hydrophobic polyisocyanate aqueous dispersion containing a pyrazole block hydrophobic polyisocyanate represented by the following general formula (I) and a nonionic surfactant, and a foot having a perfluoroalkyl group having 6 or less carbon atoms Contains water and oil components. Formula I In the formula (I) m is an integer of 2 or more, R is a residue other than the m isocyanate groups from the polyisocyanate compound having m isocyanate groups, Z may be the same or different and is a residue other than a hydrogen atom from an active hydrogen-containing compound capable of reacting with an isocyanate group, and at least two of Z's are pyrazole groups represented by the following formula (II). (II) In the above formula (II) n is an integer of 0 to 3, and when n is 1 or more, R ¹ may be the same or different and is an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aralkyl group having 7 to 12 carbon atoms, A carbamoyl group, a phenyl group, -NO ₂ , a halogen atom or -CO-OR ² (wherein R ² is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms).
