    Abstract: Textiles substrates, e.g., cotton fabrics, are conditioned to impart good feel and hydrophilicity thereto, by impregnating same with an effective conditioning amount of a polydiorganosiloxane containing, per mole, at least two structural units of the formula:XR.sub.a SiO.sub.(3-a)/2in which X is a radical: ##STR1## R' is a linear or branched C.sub.2 -C.sub.8 alkylene radical; R" is a hydrogen atom or a C.sub.1 -C.sub.6 alkyl radical; the radicals R, which may be identical or different, are each a phenyl radical, a 3,3,3-trifluoropropyl radical or an alkyl radical having from 1 to 4 carbon atoms; a is either 1 or 2; n is a number ranging from 1 to 10; and t is 0 or 1.

    Abstract: The invention concerns a method for extracting by electrodialysis a compound comprising at least amine functions capable of protonation from a liquid medium. More particularly it concerns a method for extracting, and separating at least the monomers comprising amine functions capable of protonation from a liquid medium derived from the hydrolysis of polyamides. The method of extraction from a liquid medium consists in subjecting to protonation the amine function(s) of the compounds to be extracted by adjusting the pH of the medium and in separating the compounds by passing them through a cationic membrane under the effect of an electric current. The invention is particularly applicable in processes for the chemical stabilisation of polyamides such as the PA 66 PA 6.
