본 발명은, (a) 식:CH=C(-X)-C(=O)-Y-Z-Rf [식 중, X는 메틸기를 제외한 1가의 유기기 또는 할로겐 원자이고, Y는 -O- 또는 -NH-이고, Z는 직접 결합 또는 2가의 유기기이고, Rf는 탄소수 1 내지 6의 플루오로알킬기임]로 표시되는 불소 함유 단량체, (b) 할로겐화 올레핀 단량체, 및 (c) 필요에 따라서 사용하는, 불소 원자를 갖지 않고, 적어도 1개의 탄소-탄소 이중 결합을 갖는 비불소 단량체로부터 유도된 반복 단위를 갖는 불소 함유 중합체이며, 불소 함유 중합체의 160℃에 있어서의 동적 점탄성이 100㎩·s 이상이며, 이 불소 함유 중합체를 포함하여 이루어지는, 투습성, 내수성 및 내세탁성이 우수한 투습 방수 포백용 처리제이다. The present invention is a treatment agent for a moisture-permeable fabric having excellent moisture permeability, water resistance and launderability. The treatment agent comprises a fluorine-containing polymer having repeating units derived from: (a) a fluorine-containing monomer represented by the formula, CH2=C(-X)-C(=O)-Y-Z-Rf [wherein, X is a monovalent organic group excluding methyl groups, or a halogen atom, Y is -O- or -NH-, Z is a directly-bonded or divalent organic group, and Rf is a fluoroalkyl group with 1 to 6 carbons]; (b) a halogenated olefin monomer; and (c) a fluorine-free monomer that is used as necessary, does not have a fluorine atom, and has at least one carbon-carbon double bond. The dynamic viscoelasticity of the fluorine-containing polymer at 160°C is at least 100 Pa.s.
