Process for the treatment of wool with polyorganosiloxanes

Claim 1

A process for the treatment of fibrous materials which comprises the steps of treating the fibrous materials with a composition containing: a component A selected from the class consisting of polyorganosiloxanes of the general formula ##EQU3## in which n has an average value in the range 1.8 to 2.2, and R represents organic radicals attached to the silicon atoms by carbon-silicon bonds; wherein between 1.0 and 50% of the radicals R consist of one or more organic radicals containing an epoxide group and selected from the class consisting of: 1,2-epoxyethyl; 3,4-epoxycyclohexyl; 6-methyl-3,4-epoxycyclohexyl; 3,4-epoxycyclohexyl-1-ethyl; 9,10-epoxystearyl; 3-(2,3-epoxypropoxyl)propyl; p-(2,3-epoxybutyl)-phenyl; and 3-(3,4-epoxybutyl)cyclohexyl, and the remainder of the radicals R consist of one or more organic radicals selected from the class consisting of alkyl and aryl radicals; selected from the group consisting of: (a) Diamines of the type NH 2 (CH 2 ) n NH 2 , where n is 10 or greater; (b) Amines of the type YNH(CH 2 ) n NH 2 , where n is 2 or greater; and Y is an alkyl radical containing more than 10 carbons; (c) Linear or branched polymers of ethylene oxides or propylene oxides with terminal 2-aminoethyl or 2-aminopropyl either groups or mixtures of said polymers; (d) Di- and higher amines prepared by the reduction of the nitriles of the polymers of unsaturated fatty acids; (e) Products from the reaction of (d) with acrylonitrile which have been subsequently hydrogenated; or an amine component C wherein C is an amine of the type R'''NH 2 or R 2 '''NH wherein R''' is an alkyl or alkenyl group containing twelve or more carbon atoms; or a mixture of components B an C; and allowing the components A and B to react chemically.
