The invention relates to a method for treating fibrous substrates consisting in treating said fibrous substrates with (a) at least one type of oligomer of branched or non-branched C3-C10 alkene with a mean molecular weight Mn of up to 1200 g/mol, (b) at least one emulsifier obtained by copolymerisation of (A) at least one ethylenically unsaturated dicarboxylic acid anhydride derived from at least one type of dicarboxylic acid having from 1 to 8 C atoms, (B) at least one type of branched or non-branched C3-C10 alkene oligomer, at least one type of oligomer with a mean molecular weight Mn of up to 1200 g/mol, (C) at least one alpha - olefin having up to 16 C atoms and (D) optionally, at least one other type of ethylenically unsaturated comonomer and an optional reaction with (E) of at least one compound of general formula 1a, 1b, 1c, or 1d optionally followed by a contact with water, wherein the variables of formulas from 1a to 1d are defined as follows: A<1> is C2-C20 alkylene, R<1> is linear or branched C1-C30 alkyl, phenyl or hydrogen and n is a number other than 1 to 200. |
