| abstract |
The invention relates to a method for treating organic fibres in jet dyeing machines by means of aqueous formulations of aminofunctional organosilicon compounds containing (a) at least one siloxane unit of general formula (I) wherein R is the same or different and represents a monovalent, optionally halogenated hydrocarbon radical comprising 1 to 18 carbon atoms per radical; R<1> is the same or different and represents a hydrocarbon radical comprising 1 to 8 carbon atoms per radical; a represents 0, 1, 2 or 3, b represents 0, 1, 2 or 3, and c represents 1, 2 or 3, provided that the sum of a+b+c is less than or equal to 3; Y represents a monovalent organic radical comprising at least 2 positively charged nitrogen atoms, provided that at least three carbon atoms which can be optionally split or substituted by separate heteroatoms are found respectively between the positively charged nitrogen atoms in radical Y, and provided that the organosilicon compounds contain at least 0.35 wt. % of positively charged nitrogen atoms, and (b) at least one siloxane unit of general formula (II) wherein R, R<1>, a and b have the designation cited above, provided that the sum of a+b is less than or equal to 3. |
