Abstract:
1. A method for treating a textile material in order to provide the textile material with a soft feel, absence of yellowing and good hydrophilicity, the method comprising contacting the textile material, with an aqueous emulsion comprising water, a surfactant and at least one linear, cyclic or three-dimensional polyorganosiloxane of formula (I): in which: (1) the symbols Z, which are identical or different, represent R (2) the symbols R (3) the symbols V, functional groups which are identical and/or different, represent a group containing a sterically hindered piperidinyl functional group or groups selected from: for the groups of formula (II): R 4 is a divalent hydrocarbon radical selected from: linear or branched alkylene radicals having 2 to 18 carbon atoms; alkylene-carbonyl radicals in which the linear or branched alkylene portion contains 2 to 20 carbon atoms; alkylene-cyclohexylene radicals in which the linear or branched alkylene portion contains 2 to 12 carbon atoms and the cyclohexylene portion contains an OH group and optionally 1 or 2 alkyl radicals having 1 to 4 carbon atoms; radicals of formula —R radicals of formula —R radicals of formula —R radicals of formula —R U represents —O— or —NR in which: R the radicals R the radical R for the groups of formula (III): R′ 4 is selected from a trivalent radical of formula: where m represents a number from 2 to 20, and a trivalent radical of formula: where p represents a number from 2 to 20; U′ represents —O— or NR 12 —, with R 12 being a radical selected from a hydrogen atom, a linear or branched alkyl radical containing 1 to 6 carbon atoms; R 5 and R 6 have the same meanings as those given with respect to the formula (II); and (4) the number of units ηSi with no group ranges from 50 to 250, and the number of units ηSi with a group V ranges from 1 to 3 and 0≦w≦10 and 8≦y≦448.
