摘要

b "composition, method of providing resistance to dirt and resistance to stains for acid dyes to a substrate of fiber and fiber of polyamide, polyester,Polyolefin or wool " d , the present invention relates to a terpolymer which has units of formula (I), in which X is a radical (C ~ 2 - 10 ~ alkyl.C ~ 6 - 12 ~ arila or C ~ 4 - 12 ~ alcu00f3xi; D is about 3 to 50; R is a radical fluoroalquila R ~ F ~ - (a) ~ V ~ ((b) ~ W ~ -; R ~ F ~ is a linear or branched aliphatic radical fully fluorinated and optionally intErrompido by at least one oxygen atom; a is a radical selected from divalente only ~ 2 ~ n (R '') -, - con (R '') -, - S - or so ~ 2 ~ -.Where R '' is h or a radical C ~ 1 - 6 ~ alkyl; B is a linear hydrocarbon radical divalente - C ~ t ~ H ~ 2T ~ -, in which t is 1 to 12; y is a radical divalente ch ~ 2 ~ -; u, V and W are,Independently from each other, zero or 1; R 'is hydrogen or methyl; and it is about 0.05 to about 10; m is hydrogen.Alkali metal or ammonium; and (f) is about 5 to about 40; and its use to provide resistance to dirt and stain resistance by acid dyes to fiber substrates.
