Method of treatment of a textile or non-woven substrate to render same water and oil repellent |
摘要 |
The present invention relates to a method of treating a non-woven substrate or textile, comprising the step of applying to said non-woven substrate or textile a fluorochemical composition comprising a fluoropolymer that comprises:(a) between 10 and 97 mole % of units that can be derived from fluorinated monomer selected from the group consisting of monomers according to the general formula: R<SUB>f</SUB>-X-OC(O)-C(R)-CH<SUB>2 </SUB>wherein R<SUB>f </SUB>represents a perfluorinated aliphatic group having 3 or 4 carbon atoms, X is an organic divalent linking group and R represent hydrogen or a lower alkyl group having 1 to 4 carbon atoms; (b) between 3 and 75 mole % of units derived from a chlorine containing comonomer selected from the group consisting of vinylidene chloride, vinyl chloride and mixtures thereof; and (c) optionally further units derived from monomers other than a fluorinated monomer and said chlorine containing comonomers; wherein the amount of units (a), (b) and (c) adding up to 100%, whereby said fluorochemical composition is applied in such amount that the weight of fluoropolymer on said non-woven substrate or textile is not more than 3% by weight based on the weight of said non-woven substrate or textile.
