Abstract: Disclosed is a nonwoven fabric formed from (i) a nonwoven fabric substrate and (ii) a fluorine-containing polymer adhering to the nonwoven fabric substrate, wherein the fluorine-containing polymer contains:(a) repeating units formed from a fluorine-containing monomer which is alpha-chloro acrylate or alpha-chloro acrylamide containing a fluoroalkyl group, and (b) repeating units formed from a halogenated olefin monomer, and the fluorine-containing polymer is free from repeating units formed from a (meth)acrylate containing a linear or branched hydrocarbon group having at least 18 carbon atoms.

Abstract: Provided is a fluorinated polymer that can impart excellent washing durability and water- and oil-repellency to fibers, said fluorinated polymer having a repeating unit derived from a fluorinated monomer (a) that comprises a first fluorinated monomer (a1) represented by the formula: CH2═C(—X1)—C(═O)—Y1—Z1—Rf1 [wherein X1 represents a halogen atom; Y1 represents —O— or —NH—; Z1 represents a direct bond or a bivalent organic group; and Rf1 represents a fluoroalkyl group having 1 to 20 carbon atoms] and a second fluorinated monomer (a2) represented by the formula: CH2═C(—X2)—C(═O)—Y2—Z2—Rf2 [wherein X2 represents a monovalent organic group or a hydrogen atom; Y2 represents —O— or —NH—; Z2 represents a direct bond or a bivalent organic group; and Rf2 represents a fluoroalkyl group having 1 to 20 carbon atoms].
