The present invention provides a moisture-permeable waterproof fabric excellent in moisture permeability, water resistance and washing resistance. The present invention provides a fluorine-containing treatment agent for a moisture-permeable waterproof fabric, comprising: a fluorine-containing polymer having a repeating unit derived from the following (a) to (c), and the fluorine-containing polymer is at 160 ° C The dynamic viscoelasticity is 100Pa. s or more, the formula (a): CH2=C(-X)-C(=O)-YZ-Rf is a fluorine-containing monomer [wherein, X is a monovalent organic group or a halogen atom other than a methyl group. , Y is -O- or -NH-, Z is a direct bond or a divalent organic group, Rf is a fluoroalkyl group having 1 to 6 carbon atoms, (b) a halogenated olefin monomer, and (c) as needed A non-fluorine monomer which is free of fluorine atoms and has at least one carbon-carbon double bond. |
